Maintenance Specification 2 General Requirements

Issue 2: WORKING PBC-01 ‘Bay Roads’ MS 1

1 1. General Requirements

1.1 Contract Description

The scope of the PBC-01 ‘Bay Roads’ includes the provision of all products and services associated with the planning and delivery of network maintenance activities for the combined Western Bay of Plenty District Council (WBoPDC) and Transit New Zealand (Transit) roading networks in the Western Bay of Plenty region. The WBoPDC network comprises approximately 712km of sealed and 330km of unsealed road including 125km of urban road with a speed limit of 70 kph or less. Transit’s roading network length consists of approximately 122km of State Highway including approximately 8km of urban State Highway with a speed limit of 70 kph or less.

The PBC is a single contract which will replace existing road management and maintenance contracts in the Western Bay of Plenty region. The PBC seeks to maximise the skills, expertise, innovation and systems of the roading industry to provide better outcomes and thus better value for money.

Fundamental to the concept of performance based contracting is the need for a cooperative approach by the contracting parties. The conditions of contract seeks to remove the traditional adversarial relationship between Principal, consultant and contractor.

To achieve the objectives of compliance monitoring within the PBC environment the Contractor implements its own compliance monitoring system to monitor its performance and to demonstrate compliance with Performance Criteria throughout the term of the PBC sufficient to stand scrutiny under review by the Superintendent or those nominated by the Superintendent. The output from the Contractor’s compliance monitoring system does not provide a direct input into the non compliance system based on the issue of non compliance notices by the Superintendent (refer Maintenance Specification Clause 5.4).

Certain data collection required by the Contractor for compliance demonstration is identified as to be collected via an independent data collection contract jointly commissioned by the Principal and the Contractor (refer Maintenance Specification Clause 3.1.1). The Contractor’s demonstration of compliance resulting from the data output from the data collection contract and specifically required Contractor’s inspections will provide a direct input into a non compliance system

The Superintendent will also review the Contractor’s systems, procedures and records and may inspect the Assets. The Principal may contract, at its cost, with an independent party to conduct formal inspections of the Contractor’s performance, annually or as otherwise required by the Superintendent. The Superintendent’s reviews and Superintendent commissioned inspections and reviews will provide a direct input into a non compliance system.

The PBC is a lump sum contract. The tendered lump sum includes all costs to: • bring the Assets to the contracted standard



1 • provide all inspections (other than the Principal’s cost component of the

jointly commissioned data collection contract) • manage the integrity of the Assets through a cost effective long term

maintenance strategy; and • provide identification, programming, prioritization and delivery of

maintenance services necessary to achieve specified Performance Criteria

Monthly payments will be made to the Contractor for the Services throughout the term of the contract, in accordance with Basis of Payment Clause 2.1. Payment is independent of actual works and services provided but may vary within specified margins to reflect the Contractor’s performance in specific areas and subject to other adjustments provided for in the Contract Documents.

Innovation is strongly encouraged under the PBC. The Contractor is expected to develop innovative ways of providing the Services and achieving the Performance Criteria.

A risk is an uncertain event which when it occurs, may have a material effect on the extent of the Services to be performed by the Contractor or on the cost to the Contractor of performing the Services. The Principal is seeking to achieve price certainty with regard to the PBC. In this regard the Principal seeks to allocate risks to the party best able to manage it. Except where explicitly stated to the contrary in Appendix A1.1 the Contractor bears all risk in the lump sum tendered price.

1.1.1 Services

The Services include the provision of all products and services required to achieve the Performance Criteria and other requirements as set out in the Contract Documents. This includes, but is not limited to:

1.1.3 Contract Outcomes

The Principal’s overall objective to provide a safe and efficient network with the highest level of availability to road users and which satisfies stakeholder expectations is underpinned by the following eight outcomes.

The outcomes are:

a) Safety – Foster a network for road users and to support innovation in the development of techniques that: • manage traffic safely



1 • provide road users with realistic perceptions of danger • provide consistent, safe and forgiving road environment with no surprises for

road users • provide a safe working environment for maintenance and construction

c) Environment and Aesthetics - To avoid, remedy or mitigate, as far as possible, the adverse effects of road maintenance and construction activities and road use on the environment

d) Asset Management - Optimise long term road maintenance to achieve desirable long term condition and mitigate against the effects of traffic growth

e) Preventive Maintenance - Protect the long term reliability of the road network by proactive and innovative preventive maintenance

f) Contract Delivery - Use a systems approach to deliver the Services within the lump sum

g) Culture - Encourage a co-operative environment for all parties involved in the contract to achieve the necessary outcomes

h) Services - Improve reliability of travel, minimise travel disruptions and keep road users informed.

1.1.4 Specific Requirements

The Performance Criteria which underpin the outcomes are described in Maintenance Specification, Sections 22 – 55 inclusive. They include the:

a) Management Performance Measures, (see Maintenance Specification, Section 22)

b) Key Performance Measures, (see Maintenance Specification, Section 33)

c) Operational Performance Measures, (see Maintenance Specification, Section 44)

d) Compliance Monitoring, (see Maintenance Specification, Section 55)

1.2 Limit of Works

Appendix A5 sets out the Carriageway Sections, as defined in the RAMM database, within the Limit of Works at year 0 of the Contract for the PBC-01 ‘Bay



1 Roads’ comprising the combined WBoPDC and Transit roading networks in the Western Bay of Plenty region.

The road network on Matakana Island and that within the Tauranga City Council region are not included within the Limit of Works.

As is identified within the risk allocation in Appendix A1.1 the Limit of Works may expand over the duration of the of the PBC with additional Assets in the form of subdivisional roads and associated assets, earth retaining structure and bridges.

For the purposes of this Contract the lateral Limit of Works is the legal road reserve boundaries as defined in Terralink’s Terraview Version 4 except where:

a) for road groups 1 and 2 an existing fence line lies within the road reserve boundary, the Limit of Works shall be defined by the fence line

b) for road groups 1 to 7 the existing road is located only partly within the legal road reserve, the Limit of Works shall be defined by the existing fence line, the top of a cut batter or toe of a fill batter, whichever is of greater offset from the road centreline but extending to and inclusive of drainage and/or stabilising berms and the inlet or outlet structures of any culverts under the road.

Appendix A1.2 lists the land entry agreements that have been made for access into adjoining properties to complete routine maintenance work. The Contractor must comply with the specific requirements of each agreement.

1.2.1 Road Groups

Each Carriageway Section within the Limit of Works is categorised as within a road group from 1 to 7. This categorisation is primarily based on the function and/or traffic exposure of the Carriageway Section under consideration in accordance with the following:

State Highway Carriageway Sections within the Limit of Works are either categorised as within road group 1 or road group 2. State Highway north of Paengaroa are categorised as road group 1 including State Highways 2 and 29. State Highway south of Paengaroa are categorised as road group 2 including State Highway 2 and 33. As the State Highways categorised as road group 1 typically have a higher exposure to traffic than those categorised as road group 2 they are generally required to be maintained to a relatively higher standard as per the respective Performance Criteria.

Unless otherwise negotiated by the Management Board, the road grouping of the State Highway Carriageway Sections are fixed for the duration of the Contract.

WBoPDC local road Carriageway Sections within the Limit of Works are categorised as within a road group from 3 to 7. This categorisation is in accordance with the Average Daily Traffic (ADT) being the statistical mean of averaged daily traffic counts from the three calendar years prior (refer Table



1 1.2.1) as taken from the RAMM Carriageway Table. Consequently, individual local roads may comprise various Carriageway Sections of differing road group classification. In line with changes in ADT, the road group categorisation of any Carriageway Section may also change within the duration of the PBC. Note that the ADT will be updated annually in line with traffic count data collected through the Jointly Commissioned Data Collection Contract in accordance with Maintenance Specification Clause 3.1.1. In the event that a Carriageway Section is re-categorised, the Contract Standard for the affected road groups will remain fixed and no change will be negotiated to the lump sum.

For example a Carriageway Section originally categorised as road group 4 will change to road group 3 with an ADT rise from 450 to 550. In this event regardless of the existing condition of the Carriageway Section at the time of re-categorisation, the Contract Standards associated with the road groups 3 and 4 will remain fixed and the lump sum will not be renegotiated.

Table 1.2.1: Road Grouping

Road Group Average Daily Traffic (ADT)

3 ADT ≥ 500 4 200≤ADT<500 5 100≤ADT<200 6 30≤ADT<100 7 ADT<30

For a full description of road groups 3 to 7 refer to the WBoPDC document Asset Management Plan clause 6.3.1.

1.2.2 Sub-Group

As identified in AppendixA5 each Carriageway Section is further categorised into sub-groups for Performance Criteria specification. Both the Contract Standard for Key Performance Measures and the Contract Standard and Response Time for Operational Performance Measures may be assigned for individual road groups and/or sub-groups as defined in the Contract Documents.

Each Carriageway Section categorised as road group 1 to 7 are further sub-grouped as either located within an urban or rural area. For the purposes of this Contract urban areas are those where the posted speed limit is 70km/hr or less. All other areas are rural areas. For the definition of certain Performance Criteria each Carriageway Section within road groups 3 to 7 are further sub-grouped by function (collector, residential,



1 industrial), and/or its community area and the terrain through which it passes (level, hilly, mountainous). The sub-group categorisation of each Carriageway Section within road groups 3 to 7 are available within the RAMM database. Carriageway Sections within road groups 1 and 2 which are within urban areas are also further sub-grouped into the community area through which they pass.

1.2.3 Entities Comprising the Principal Statutory Responsibility

The entities comprising the Principal have a statutory responsible for all Assets associated with their respective road networks in accordance with the following:

Transit is responsible for all Assets associated with Carriageway Sections categorised as within road groups 1 and 2 with the exception of Assets, associated with Carriageway Sections in urban areas, which are located outside of the kerb lines or where no kerb line or equivalent exists outside of:

i) 1.0m outside of the invert of the existing surface water channel, of whatever form or

ii) 5.0m beyond the edge of seal

whichever is greater.

The WBoPDC is responsible for all Assets associated with Carriageway Sections categorised as within road groups 3, 4, 5, 6 and 7 in addition to Assets associated with Carriageway Sections categorised as within road groups 1 and 2 in urban areas for which Transit has been identified as not responsible above. At intersections the definition of responsibility shall be as set out in the Transit State Highway Control Manual.

1.3 Handover and Handback

The existing network maintenance and management contracts include provision for total responsibility to be transferred to the Contractor on the Commencement Date with a requirement for one calendar months notice to the incumbent consultants and contractors, with the exception of the current Limited Access Road declarations listed in Appendix A1.3 which will be completed by the incumbent consultant.

The Principal will be responsible for negotiating with all incumbent contractors and consultants regarding handover of the Assets to the Contractor.

The incumbent network maintenance contractor utilises various equipment and material including:

a) temporary signs and signals



1 b) fencing

c) miscellaneous tools and materials

Any such equipment or material that is the property of the Principal will be made available to the Contractor within two weeks of the Commencement Date at no charge.

The Contractor shall ensure continuity of all temporary works that are provided to mitigate a safety hazard.

All temporary signs, signals and fencing in the Contractors possession that are being used to provide the Services at the completion of the Contract shall become the property of the Principal. No payment for such equipment and materials will be made to the Contractor.

1.4 Ownership

Although ownership of the Assets remains with the Principal, the Contractor is encouraged to develop a sense of ‘ownership’.

The Contractor is expected to proactively assume responsibility on the Principal’s behalf for the implementation of the Principal’s policies, particularly in the areas of information management, network controls and safety. This includes being accountable for the content and accuracy of Annual Plans and forward capital works programmes .

The Contractor shall pursue a strategy of proactive preventive maintenance to minimize safety hazards and to minimize potential capital works needs due to lack of maintenance.

The Contractor shall maintain a responsibility for ensuring safety, good public relations and compliance with the Principal’s standards in areas of the network where other consultants are concurrently working. Generally, the Contractor will raise any concerns initially with the other consultant, but, in urgent situations, the Contractor shall take immediate action to ensure public safety or protect the Principal’s interests. The Principal will enter into separate professional services contracts for services which do not fall within the Services, some management related professional services, and for the implementation of some aspects of the National Roading Programme. Those contracts may include, but are not limited to the activities excluded from the Services as described in Maintenance Specification, Clause 1.1.11.1.1.



1 1.5 Cost Recovery

The Contractor is responsible for the day to day management of network control as described in the Maintenance Specification. The cost of these activities is included in the lump sum.

Where the Principal would normally be entitled to recover its costs in respect of any network control activity, the Contractor may attempt to recover its costs for performing these activities from parties other than the Principal.The Principal shall be under no obligation to assist in such cost recovery other than to provide the Contractor with delegated authority to seek recovery.

Cost recovery for damage to Assets shall be treated in accordance with Conditions of Contract Clause 1.5.12.

1.6 Preventive Maintenance and Minor Safety Works

Proactive preventive maintenance and minor safety works are considered to be in the best interests of both the Principal and the Contractor.

As part of the interactive tender process, facilitated variation benchmarking sessions will be undertaken. The objective of these sessions is to address aspects of the PBC, which may be subjective with respect to the Services under the lump sum, to align all parties on the issue of variations and to ensure alignment within the lump sum and risk allocation. Where the outputs of the variation benchmarking sessions do not clearly establish responsibility for a particular item of preventive maintenance or minor safety work, responsibility shall be allocated in keeping with the intent of the variation benchmarking for other items of preventive maintenance or minor safety works as appropriate.

Timely effective measures focused on minimising consequential damage, safety hazards, inconvenience to motorists and future costs, are strongly encouraged by the Principal. It is envisaged such work may include clearing culvert inlets and outlets, gravity retention walls, horizontal drainage of slips, diverting of surface water away from areas of instability, soil conservation planting, grassing down, toe weighting, the use of geogrid and geotextiles, rip rap protection, in stream channel works, relocating or adding new signs, backdrop planting to curves, relocation of obstructions, addition of new pavement markings and like measures.

For road groups 1 and 2 the Contractor shall maintain a comprehensive list of preventive maintenance opportunities, prioritised using objective criteria, which shall periodically be referred to the Principal including where appropriate justification reports for separate funding for a decision where the preventative maintenance is considered outside of the lump sum.



1 For road groups 1 and 2 the Contractor shall maintain a comprehensive list of minor safety works prioritised using objective criteria which shall be included in the Safety Management and Intervention Plan and referred to the Principal including where appropriate justification reports for separate funding for a decision where the minor safety work is considered outside of the lump sum.

For road groups 3 to 7 the Contractor shall assess and implement preventive maintenance and minor safety work strategies to achieve Performance Criteria. All such preventive maintenance and minor safety work is included within the lump sum.

1.7 Incident Response

The Contractor is required to provide a 24 hour, seven day a week timely Incident Response service.

Emergency Works other than Incident Response and resulting from a risk allocated to the Principal in Appendix A1.1 shall be treated as additional works in accordance with Maintenance Specification, Clause1.8.

1.8 Additional Works

Additional works shall be Directed in accordance with Conditions of Contract Clause 1.7.2.4 such that nothing in the Contract prevents the Principal from engaging another contractor to perform work or services, which if carried out by the Contractor, would require a variation of the Services.

The Contract provides discretion to the Superintendent with respect to the execution of additional works by the Contractor up to a total cost of $400,000 on road groups 1 and 2 and $75,000 on road groups 3 to 7. To this extent where the Superintendent assesses a benefit exists to the Principal, which may take the form of:

• expedited work

• increased efficiency and/or

• reduced administration costs.

the Superintendent may at his sole discretion Direct additional works which do not form part of the Services.

The $75,000 and $400,000 limits may be adjusted by the Principal at the end of years 3 & 6 of the Contract period. The Principal’s decision as to any revised level for additional works will be final.

1.9 Other Contractors

Contractors may be working within the Limit of Works at various times. This work may include capital works projects, installation of services, etc including activities at the time of handover.

1.9.1 Current Contracts

Appendix A1.4 lists the: a) Carriageway Sections under the control of other contractors as at the

Commencement Date b) the type of work c) due date of completion of the contract and/or period of defects liability d) contact person and contact numbers.

1.9.2 Maintenance Responsibility

The Contractor is required to manage all activities within the Limit of Works to the extent that it is necessary to ensure the safe and efficient movement of traffic at all times, and that the quality of the Assets are not compromised by the activity or inactivity of others.

The presence of other contractors does not relieve the Contractor of its obligations to maintain the Assets according to the Contract Documents, unless the presence of other contractors directly affects the Services where the Contractor will not be responsible for the maintenance of:

a) those Assets included within the limits of a capital works contract being undertaken within the Limit of Works under another contract between the date of possession of site and the date of practical completion of those other contracts.

b) any assets which have been upgraded as a capital work under other contracts and, for the time being, are the maintenance responsibility of another contractor between the date of practical completion and the end of the defects liability period of those other contracts.

A joint inspection, conducted by the Superintendent and the Contractor on practical completion of other contracts performed within the Limit of Works or for other Assets to be added to the Limit of Works, will identify any particular maintenance or omission responsibilities of the other contractor that may exist at the date of practical completion. The Contractor will be responsible for ongoing day to day and periodic maintenance to any assets that lie within the limit of works



1 of other contracts between the date of practical completion and the end of the defects liability period of those other contracts.

A joint inspection, conducted by the Superintendent and the Contractor at the end of the defects liability of other contracts, will identify any particular maintenance or omission responsibilities of the other contractor that may exist at the end of the defects liability period. The Contractor will not resume responsibility for the Assets in question until the identified reasonable responsibilities of the other contractor are discharged, but only to the extent that such responsibilities have not been discharged.

1.10 Additional Assets

For road groups 1 and 2, the lump sum will be adjusted for any significant additions to or deletions from the Assets for example of the order of highway lighting gantry, made from time to time during the term of the Contact, in accordance with the Conditions of Contract.

For the road groups 3 to 7, except as limited by the Conditions of Contract and the risk allocation identified in Appendix A1.1, the Contractor is responsible within the lump sum for all additional Assets created by itself and others during the term of the contract, including the following: a) Development works and capital improvement works carried out by the

Contractor as part of the Services b) New subdivision roads and associated road related assets constructed by

others c) Improvements to any of the Assets carried out by the Principal or its agents d) New assets, including roads, bridges and other road asset items constructed

by the Principal or its agents

The Contractor will be given the opportunity to comment on the standard of any new asset being constructed by others, at the appropriate times during the design and construction of the new assets.

1.14 Publications and Standards

In addition to this Maintenance Specification unless specified otherwise the standard specifications listed in Appendix A1.6 and publications listed in Appendix A1.7 form part of but are not reproduced in the Contract Documents.

If there is any ambiguity or contradiction between this Maintenance Specification and any publication or standard specification, this Maintenance Specification will take precedence.

1.14.1 Resource Consents

The Contractor will be responsible for the annual charges and all other costs associated with resource consents other than those resource consents related to capital works and maintenance projects on road groups 1 and 2.

The Contractor will be responsible for renewal of the resource consent as may be necessary for continued execution of the Services. The Contractor will be



1 responsible for all costs associated with such renewal or procurement except as specified in Conditions of Contract, Clause 1.11.6.3.

The Contractor must comply with the conditions of such resource consents and the requirements of Appendix A2.2.6.

1.15 Electricity

The Contractor will be responsible for all costs and charges associated with the supply of electricity to all relevant Assets and electricity consumed by the Assets.

1.16 Stockpile and Disposal Areas

1.16.1 Principal’s Areas

Appendix A1.8 and A1.9 lists the stockpile and disposal sites respectively which may be used by the Contractor. The use and management of stockpile areas is to be undertaken in accordance with the Council document Use and Management of Stockpile Areas as issued to Tenderers.

In general, these areas must be maintained to a condition no worse, including the avoidance of the introduction of noxious weeds and pests, than that existing at the Commencement Date. The incumbent network maintenance contractor will be given, with the notice of termination, one month in which to remove its materials from the stockpile sites. After such notice has expired the ownership of the stockpile material will pass to the Contractor.

1.16.2 Other Areas

The Contractor:

a) is responsible for locating, gaining legal entry to, establishing, maintaining access and drainage, controlling work and reinstatement of other stockpile and disposal areas

b) must notify the Superintendent of the location of all disposal sites and, prior to their use, must submit copies of any resource consent(s) required for these areas

c) must provide written evidence that the conditions have been fulfilled



1 1.17 Underslip Minimum Repair Standard (Road Groups 3 to 7)

The Contractor is required to repair any underslip which occurs on road groups 3 to 7 to a minimum width of 0.3m from the outside of the original edge of the seal or carriageway (prior to the slip) plus an additional width determined in accordance with Table 1.17. The objective of the additional width is to take into account environment factors associated with the Carriageway Section including terrain, width, road group and speed zone. The repair is to be completed at grade with the existing seal.

For the derivation of the additional width the terrain type, existing width, road group and speed zone are taken from the RAMM carriageway table current at the time of the underslip. The number of metres underwidth are determined as the difference between the required width, determined in accordance with the WBoPDC Subdivision and Development Code of Practice, and the existing width.

The additional repair width is determined as the maximum width from Table 1.17 from the four environmental factors.

The Contractor may incur a lane rental charge in accordance with Basis of Payment, Clause 3.1.2.

0.5m 0.3m 0.0m

The following example is provided for the avoidance of doubt. Where an underslip has occurred at a road segment categorised as:

• mountainous terrain • 0.5m underwidth • road group 4 • 80km/hr speed zone

From Table 1.17 the additional width is determined as 0.5m required as a result of the mountainous terrain being greater than the 0m required for the 0.5m underwidth, the 0.3m for the road group 4 and the 0.3m for the 80km/hr speed zone. The total repair width required from the outside edge of the original seal or carriageway (prior to the slip) is therefore the minimum 0.3m plus the additional 0.5m (total 0.8m).

1.18 WBoPDC Call Centre

For the duration of the Contract the WBoPDC will operate a call centre and computerised service request system. A direct digital access link to the WBoPDC system will be provided for the Contractor’s use at no rental cost. The Contractor shall use the services of the WBoPDC call centre to register service requests for any aspect of the roading system associated with road group 3 to 7 and shall maintain the service request system as operated by the WBoPDC.

1.19 Corporate Documentation

All corporate documentation produced by the Contractor shall boldly display the WBoPDC call centre 0800 number as the number to be used to register complaints on the roading system and shall have the WBoPDC and Transit logos displayed more predominantly than that of the Contractor.

Maintenance Specification 1 Key Performance Measures


3 3. Key Performance Measures

3.1 Definitions

Key Performance Measures reflect the overall condition of both the primary (pavement) and secondary (bridges, drainage and minor structures, carriageway lighting, rural bus shelters and footpaths) Assets and the overall safety performance of the maintained network. The Contractor must comply with the following Key Performance Measures.

Contract Standard, in respect of Key Performance Measures, means the minimum standard that the Contractor must demonstrate compliance with at specific times throughout the Contract. Unless stated otherwise within the Tender Documents, all required data for compliance demonstration shall have been collected by no later than 28 February of each year and interpreted by the Contractor and compliance demonstration presented to the Management Board by no later than 30 June of that same year. To 28 February 2003 duplication of data collection associated with the benchmarking surveys (refer Maintenance Specification Clause 5.2.2) for the purpose of compliance demonstration shall not be required.

Where N/A is denoted in any table within Maintenance Specification, Section 3 the Contractor is not required to demonstrate compliance at the end of the identified year of the Contract.

3.1.1 Jointly Commissioned Independent Data Collection Contract

For the purpose of collection of relevant data to benchmark Contract Standards, in accordance with Maintenance Specification Clause 3.2, and to permit the Contractor to demonstrate compliance with Key Performance Measures listed in Table 3.2, within two months of the Commencement Date an independent data collection contract is to be jointly commissioned by the Principal and the Contractor.

(PBC03.13):

Mr Peter Clark of WBOPDC is appointed Engineer to Contract 2/02 – 0056/594 Data Collection Contract (DCC-01 Bay Roads).

Mr Dave McDougall is appointed Engineer’s Representative with all the powers of the Engineer, with the exception of dispute resolution as covered by 6.3.3(a) NZS 3910, but including the responsibilities of 6.3.3(b).

The entities to the Principal and the Contractor shall be severally liable under the jointly commissioned independent data collection contract (DCC).

The objective of the DCC is to encourage joint ownership and to avoid unnecessary repetition of the collected data. All processing, interpretation and presentation of the data required to demonstrate compliance with relevant Key Performance Measures shall be the responsibility of the Contractor. The



3 Superintendent may engage others to carry out parallel data processing and interpretation.

Tenderers will be offered the opportunity to comment on draft DCC tender documents prepared by the Principal. The duration of the DCC will be based on a 3+1+1 basis. The Principal will process the DCC tender closing prior to the award of the PBC. On award of the PBC the Contractor will participate in the tender evaluation for the DCC.

The administration of the DCC is to be directed by the Management Board. At their first meeting the Management Board shall select a project manager to manage the DCC on a day to day basis. It is anticipated that the Contractor’s Representative will be the project manager. All services provided by the Contractor in the evaluation, management and administration of the DCC shall be included in the lump sum.

Direct costs associated with the DCC shall be shared on a 50:50 basis between the Principal and the Contractor. The Contractor’s share of costs shall be provided for as a provisional sum within the Schedule of Prices.

The data collection listed in Table 3.1.1 shall be completed through the DCC. The frequency of the data collection shall be sufficient to permit the demonstration of compliance with all relevant Performance Criteria.

All other data collection required by the Contract Documents shall be the responsibility of the Contractor.

3.2 Key Performance Measure Year 0 Benchmark

The Contract Standards for Key Performance Measures listed in Table 3.2 are subject to adjustment to benchmark the condition of the Assets at year 0 in accordance with Maintenance Specification, Clause 5.2.2.



3 The Key Performance Measure benchmarking adjustment shall be determined as follows: a) the Management Board agree the benchmark value b) the benchmark value shall replace the Year 0 value c) each of the Year 1 to 10 values shall be adjusted so as to maintain the same

numerical difference in value from the Year 0 value

Compliance demonstration is not required at year 1 (by 30 June 03) for Key Performance Measures identified in Table 3.2 as subject to benchmarking adjustment. Where in Maintenance Specification Section 3 a year 1 Contract Standard is provided for a Key Performance Measure which is subject to benchmarking adjustment the value provided is not contractual but provides a representation of the required trend in performance. Demonstration of compliance for years 2 to 10 is as per Key Performance Measures which are not subjected to adjustment through benchmarking.

The following examples are provided for the avoidance of doubt:

The Contract Standard for Roughness Mean NAASRA Key Performance Measure for road group 1, sub-group ‘All’ is defined in the Tender Documents as follows;

As the Roughness Mean NAASRA Key Performance Measure is identified in Table 3.2 as subject to benchmarking adjustment, a benchmark value of 67 is determined through the DCC high speed data collection (completed by 28 February 2003) and accepted by the Management Board. In this event the following would become the Contract Standard;

In the event that alternative values specified in the Contractor’s tender are accepted for any Key Performance Measure and become the Contract Standard then they shall be subject to the same benchmark adjustment process.

As per the previous example however where the Contractor’s tender offers to reduce the Roughness Mean NAASRA Key Performance Measure in road group



3 1, sub-group ‘All’ to 66.5 by Year 10 based on the initial Year 0 value of 69 as follows.

66.5

Again a benchmark value of 67 is determined by the DCC high speed data collection (completed by 28 February 2003) and accepted by the Management Board. In this event the Year 0 value becomes 67 and the Year 10 value becomes 64.5 as follows;

66.0 65.75

65.5 65.25

65 64.75

64.5

In this example the Contractor would not be required to demonstrate compliance with the year 1 (30 June 2003) Contract Standard of 66.75. However, prior to 28 February 2004 a further DCC high speed data collection survey shall have been implemented. From the data collected the Contractor shall be required to interpret and present to the Management Board by 30 June 2004 that compliance has been achieved with the year 2 value of 66.5 and similarly for years 3 to 10.

All other Contract Standards not identified in Table 3.2 are fixed criteria and are not subject to adjustment based on the results of any benchmark survey.

An example of a Key Performance Measure which is not identified in Table 3.2 as subject to benchmarking adjustment is the Percent with Skid Resistance < Threshold Level Key Performance Measure. Where the Contractor’s tender offers no change to the Percent with Skid Resistance < Threshold Level – Category 1, road group 1, sub-group ‘All’ from that required by the Tender Documents the Contract Standard is as follows;

Contract Standard – Maximum % with Skid Resistance < 0.45 Road

For this Key Performance Measure the Contractor is required to demonstrate a reduction in Skid Resistance from the year 0 value of 12.5% to the year 1 value of 0.5% by the completion of the DCC high speed data survey completed prior to 28 February 2003. This is a contractual requirement such that compliance must be demonstrated to the Management Board by 30 June 2003.

3.4.3 Requirement to Treat Surface Texture

Contract Standard - For road groups 1 and 2, with • chipseal, or any surface where steady reduction of the

macro texture is a normal consequence of the aging of the surface ; or

• asphaltic concrete or other surfaces where the macro texture remains essentially constant, and the site has a crash history

where the Texture values generated from the DCC high speed data collection survey are less than the Threshold Level specified in Table 3.4.2.1 and Table 3.4.2.2 for urban and rural roads respectively, the road shall be treated such that; • it shall be made safe and • within 2 months of delivery of the DCC high speed data

survey the surface shall be treated to bring the Texture of the surface above the 0.7mm for urban and 0.9mm for rural roads

Treatments to the road surface texture should generally be long term repairs. Where a treatment is not expected to last for at least 12 months, a monitoring programme shall be implemented by the Contractor to ensure additional maintenance is carried out as soon as the surfacing falls below 0.7mm for urban and 0.9mm for rural roads. Where a new surfacing layer is placed the aggregate shall have a PSV as required by Transit specification T/10.

Where the road can not be successfully repaired due to weather constraints a sign shall be erected to make the road safe. In this event the surfacing must be repaired and the sign removed by the following first of November.

Maintenance Specification 1 Operational Performance Measures


4 4. Operational Performance Measures

4.1 Definition

Operational Performance Measures reflect the road users expectation about the network’s day to day serviceability. . For each Operational Performance Measure the Contractor must comply with both Contract Standard and Response Time Performance Criteria separately as defined below. The Contractor is required to develop and implement a compliance monitoring system in accordance with Maintenance Specification, Clause 5.3.1 to ensure that both Contract Standards and Response Times are being achieved.

Contract Standard, in respect of an Operational Performance Measure, means the standard the Contractor is required to comply and report compliance with at all times, regardless of whether defects have been programmed for repair within the Response Time or not. The objectives of the Contract Standard are to ensure that a measurable level of Service is maintained which reflects the road users day to day serviceability expectations on a network wide basis, and to permit auditing of the Contractors performance by the Superintendent.

Response Time means the time in which the Contractor must rectify any particular instance of a defect regardless of compliance being achieved with the Contract Standard. Unless specifically requested otherwise by the Superintendent, the Contractor is required to report compliance with Response Times only for Incident Response.

The Superintendent may choose to perform a Superintendent’s review with respect to the Contractors Response Times, for example, by recording the route position of potholes and repeating the inspection later to determine if those specific potholes have been repaired and whether the Contractor has achieved the Response Time.

Notwithstanding any of the Response Times specified within the Contract Documents, if any defect or problem arises that constitutes a potential safety hazard, the defect or problem shall be rectified as soon as possible but within 24 hours.

Within the Operational Performance Measure Clauses 4.2 to 4.21 any reference to a standard specification or publication other than those listed in Appendix A1.6 and A1.7 respectively are for purposes of terminology definition or the definition of an identified output standard or measurement convention. The Contractor is not required to comply with the methodology specified in any such standard specification or publication other than those listed in Appendix A1.6 or A1.7 respectively.

The control and maintenance types referred to in the above Appendices are:

a) Type 1 Control – all vegetation must be maintained between a minimum height of 40mm and a maximum height of 90mm. This standard applies to nominated areas, including shoulders, medians, traffic islands and highway verges within urban areas.

b) Type 2 Control – all vegetation must be maintained between a minimum height of 40mm and a maximum height of 150mm. This standard applies to rest areas.

c) Type 3 Control – all vegetation must be maintained between a minimum height of 60mm and a maximum height of 200mm. This standard applies to rural state highways.



4 d) Type 4 Control – all vegetation must be maintained between a minimum

height of 100mm and a maximum height of 400mm. This standard applies to sight benches on rural state highways and large vegetated areas.

e) Type 5 Control – this standard applies to the control of vegetation around edge marker posts, signs, sign posts, bridge end and culvert markers, culvert ends, headwall, guardrails, sight rails, surface water channels, kerb and channel, weighpits, side drains, culvert waterways bridge abutments and rest area furniture.

The extent of control is described in Clause 3.6 of the Transit’s C21 Standard Specification.

All sealed surfaces and unsealed trafficable shoulders must be vegetation free at all times. For all other surfaces where Type 5 Control is applied, Vegetation Free or Near Vegetation Free means all vegetation is controlled so:

i) The maximum vegetation height of 100mm is not exceeded

ii) The method of control: does not result in vegetation burn off or the creation of potential

burn off maintains the free flow of water to discharge points prevents mechanical damage to roadside furniture such as

signs, marker posts, guardrails etc enables missing or damaged roadside furniture such as marker

posts, signs etc to be readily identified

f) Type 6 Control – For road groups 1 and 2, this standard applies to the control of all plant pests within the Limit of Works including stockpile sites. For road groups 3 to 7, this standard applies to the control of all plant pests within stockpile sites and rest areas. Although the responsibility for control of plant pests within the road reserve, on the road frontage of private property rests with the occupiers of the adjoining land.

g) Type 7 Maintenance – this standard applies to the maintenance of gardens, planted areas and street trees. Appendix A4.4 details the specific requirements that apply to this Contract.

h) Type 8 Control – all vegetation must be maintained between a minimum height of 100mm and a maximum height of 1000mm. This standard applies to group 4 roads where there are no edge marker posts.

i) Type 9 Maintenance – this standard applies to the main street areas of Te Puke and Katikati. Footpaths, parking areas and hard surfaces must be vegetation free. Edges around all structures, gardens, footpaths, kerblines and



4 trees must be maintained and the vegetation shall be trimmed flush with the edges.

j) Type 10 Control – this standard applies to the control of vegetation on pedestrian walkways. The footpath edges and pedestrian envelope must be clear of vegetation to a height of 2.0m.

The vegetation control and maintenance areas are referred to in Appendices A4.2 and 4.3.

Note that while specific Contract Standards and Response Times for vegetation control are not prescribed for road groups 5 – 7 in rural areas, the Contractor shall allow to control vegetation as necessary in order to comply with the Operational Performance Measures associated with visibility of signs, edge marker posts, sight rails, intersections and the like.

Within the period nominated in the Contractor’s tender, the Contractor shall perform a 100% benchmarking inspection of all Assets associated with Operational Performance Measures within the Limit of Works to establish existing Defect levels and the extent to which the Assets comply with the Operational Performance Measures.

The Superintendent may, at his discretion, conduct or engage others to perform a parallel inspection.

Within one month of completion of the Operational Performance Measure benchmarking inspection the interpreted results shall be presented to the Management Board in the form of a Benchmarking Report in accordance with Appendix A2.1.3. The Management Board shall satisfy itself as to the accuracy and validity of the results and shall then decide the period within which the Contractor shall bring the condition of the Assets into full compliance with the Operational Performance Measures and any Contract Standards that apply to any staging in that period. The Management Board shall take note of the Principal’s requirement to limit this period and shall only set it above six months where such a timeframe would be unachievable.



5 With respect to Operational Performance Measures non-compliance Notices shall only be issued in the benchmarking period if the Contractor fails to comply with safety related Response Times or agreed staging requirements (see Maintenance Specification, Clause 5.4).

5.3 Compliance Monitoring

To achieve the objectives of compliance monitoring within the PBC environment there are two components to the system being the:

• Contractor’s compliance monitoring system and

• Superintendent’s review system

Contractor’s Compliance Monitoring System

The Contractor must develop, implement and manage a compliance monitoring system that:

a) objectively assesses their compliance with all Performance Criteria

b) monitors and reports compliance with all Performance Criteria, and

c) ensures appropriate corrective actions are developed, implemented, actioned and verified.

The Contractor’s compliance monitoring system must describe the process for assessing compliance for each of the Performance Criteria including:

a) the personnel responsible for: • implementing and managing the system • completing the compliance assessment

b) the inspection methodology to be used to demonstrate the satisfaction of Performance Criteria in accordance with Maintenance Specification Clause 5.3.3

c) assessing, determining and demonstrating the percentage compliance with the Contract Standard specified for each of the Performance Criteria, where appropriate

d) recording and reporting results

e) developing and implementing appropriate corrective actions

f) making all information available to permit the Superintendent to perform reviews of the system.

Other than where identified within the Contract Documents the Contractor’s inspections and compliance monitoring system do not provide a direct input in to the non-compliance system as described in Maintenance Specification Clause



5 5.4. As such a non compliance identified by the Contractor will not necessarily attracted a non compliance Notice in accordance with Maintenance Specification Clause 5.4 where the Contractor’s non compliance resolution has effectively addressed any systematic or procedural shortfall.

Superintendent’s Review System

The Superintendent will review the Contractor’s systems, procedures and records to determine their effectiveness in ensuring that the Contract Standards, Response Times and Delivery Times are being achieved.

In addition to the compliance demonstration required for Key Performance Measures in accordance with Maintenance Specification Clause 5.3.2 the Superintendent’s reviews will provide direct input into the non compliance system described in Maintenance Specification Clause 5.4.

Superintendent’s reviews may concentrate on areas where the Contractor’s compliance monitoring system has identified a systematic failure however the Superintendent may review the Contractor’s procedures and work activities and may conduct specific Asset inspections at any time.

The Superintendent’s reviews will in no way limit the Contractor’s responsibility to develop, implement and manage a Contractor’s compliance monitoring system.

5.3.1 Management Performance Measures

For each Management Performance Measure, delivery of the Services in accordance with the Contract Standards and Delivery Times is required for compliance. Compliance is required in respect of each discreet deliverable.

The Contractor shall develop and implement a Contractor’s compliance monitoring system which reports the timeliness of deliverables for each Management Performance Measure.

The Superintendent’s review will include the standard and timeliness of deliverables, and may be undertaken by the Superintendent or others engaged by the Superintendent for this purpose.

5.3.2 Key Performance Measures

The Contractor shall demonstrate compliance with Key Performance Measures in accordance with Maintenance Specification Section 3. This will provide a direct input in to the non-compliance system as described in Maintenance Specification Clause 5.4



5 5.3.3 Operational Performance Measures

The Contractor shall develop and implement a Contractor’s compliance monitoring system which reports achievement of Contract Standards and Response Times for each Operational Performance Measure.

5.3.3.1 Inspection Methodology

Within two months of completion of the Operational Performance Measure benchmarking inspection, in accordance with Maintenance Specification 5.2.3, the Contractor shall present to the Management Board an inspection procedure for each Operational Performance Measure proposed to demonstrate compliance with Contract Standards at any time throughout the duration of the PBC.

The Management Board shall satisfy itself to the extent that the proposed inspection procedure will satisfactorily demonstrates compliance with Contract Standards for each Operational Performance Measure and shall decide the inspection methodology to be adopted. The following is provided as a guide to the Management Board:

Where an Operational Performance Measure Contract Standard depends on a percentage non-compliance, for example ‘no defects shall exist within 95% of the total number of 100m sections’ the inspection methodology for compliance demonstration as part of the Contractor’s compliance monitoring system or Superintendent’s reviews may be based on any of the following inspection methodologies:

a) 100% Asset inspection of the total population: Under this inspection methodology the Management Board shall decide the frequency at which a 100% Asset inspection of the total population is undertaken. Following the 100% inspection of the total population the requirement for the demonstration of compliance with the specified minimum Contract Standard (CS%) is:

%% CSP ≥ …………………………….………….. Equation (a) where Z = the total number of units in the population z = the total number of units inspected that have no Defects

P% = total population % compliant = 100xZz

The following example is provided for the avoidance of doubt: For Shoulder Potholes the Contract Standard is defined for road groups 1 and 2 as ‘95% of all 100m sections shall be without Defect’ so that CS% = 95%.



5 As, at the time of the inspection, there is 122km of road group 1 and 2 the total number of 100m sections in the population Z = 122 x 10 = 1,220. From equation (a) the requirement for the demonstration of compliance becomes:

%95100220,1

≥xz

and rearranging for z:

159,1220,195.0 =≥ xz

In this case, compliance with the Contract Standard means that at least 1,159 of the 1,220 - 100m sections, all of which have been inspected, shall have no Defects in terms of Shoulder Potholes at each inspection.

b) Statistically Significant Asset Sample

Under this inspection methodology the Management Board shall decide the size of a randomly selected sample from the total population, which the Management Board considers will represent satisfactorily the total population. The Management Board shall also decide the frequency at which the inspection of the sample is undertaken.

The requirement for the demonstration of compliance with the specified minimum Contract Standard (CS%) is then determined in accordance with equation a) above by substituting the sample population % properties for the total population properties. The following example is provided for the avoidance of doubt: Continuing from the example in a) for Shoulder Potholes the Management Board decides that a randomly selected 40km of road group 1 and 2 is a statistically significant sample to represent the total population such that the total number of 100m sections in the sample population Zs = 40 x 10 = 400. From equation (a) the requirement for the demonstration of compliance becomes:

%95100400

≥xzs

and rearranging for zs the total number of units inspected that have no Defects:

38040095.0 =≥ xz



5 In this case, compliance with the Contract Standard means that at least 380 of the 400 randomly selected 100m sections inspected have no Defects in terms of Shoulder Potholes.

c) Statistical Inference from Asset Sample

Using statistical inference the % compliance of the total population (P%) is estimated from the % compliance derived from a randomly selected sample from the total population (Ps%).

Under this methodology the Management Board shall decide the size of a randomly selected sample from the total population, however the sample is not necessarily required to be statistically significant. The Management Board shall also decide the frequency at which the inspection of the sample is undertaken.

As the sample properties generally do not exactly represent the properties of the total population a sampling error is considered. The larger the sample size the smaller the sampling error becomes and subsequently the closer the sample will represent the total population.

Through setting an upper and lower bound confidence limit to Ps%, it is possible to predict to a level of confidence, that P% falls within the bounds of Ps% +/- confidence interval. For the purpose of compliance demonstration an 85% confidence limit shall be used to set the width of the confidence interval.

For the Contractor’s compliance monitoring system to demonstrate that P% is greater than %CS the lower bound of the 85% confidence limit must be shown to be above the % CS such that the criteria for compliance demonstration becomes:

%%85% CSCLPS ≥− ………………………….….. Equation (b)

where ZS = the total number of units in the sample zS = the total number of units inspected that have no Defects

PS% = sample % compliant = 100xZz

S

85% CL = the 85% Confidence LevelS

SS

ZPPx %)100%(44.1 −

=

and 1.44 is a constant which results from the assumptions of 85% confidence and the normal distribution of Defects over the total population.

The following examples are provided for the avoidance of doubt:



5 Continuing from the example in a) for Shoulder Potholes a sample of 200 of the 100m sections (ZS) are randomly selected from the total population of 1,220 sections. As a result it is found that 193 sections (zS) have no Defects in terms of Shoulder Potholes. From the sample results the % compliant (PS%) is determined as:

%5.96100200193% == xPS

and the 85% Confidence Level (CL) as:

%87.1200

)5.96100(5.9644.1 =−

=xx

From equation (b) the criteria for the demonstration of compliance:

%95%63.94%87.1%5.96 <=−

is not achieved so that compliance has not been demonstrated in this case. To illustrate the effect of increasing the sample size to reduce sampling error now consider the scenario where the sample size is doubled to 400 sections (XS) and the resulting % compliant (PS%) is as previously at 96.5% due to 386 sections (xS) found to have no Defects in terms of Shoulder Potholes. The 85% CL becomes:

%32.1400

)5.96100(5.9644.1 =−

=xx

and from equation (b) the criteria for the demonstration of compliance becomes:

%95%18.95%32.1%5.96 >=−

Clearly compliance has been demonstrated in this case.

Where the inspection procedure relies on statistical inference, a sufficient sample to permit the assumption of a normal distribution of Defects over the total population is required.

Under the Superintendent’s review to demonstrate non-compliance of the total population from a random sample using statistical inference the upper bound of the 85% CI must be below the % CS such that the criteria for non compliance demonstration becomes:



5

%%85% CSCLPS ≤+ ……………………….…..….. Equation (c)

The following examples are provided for the avoidance of doubt: Continuing from the example in a) for Shoulder Potholes the Superintendent randomly selects 200 of the 100m sections (ZS) from the total population of 1,220 sections where his review finds that 193 sections (zS) have no Defects in terms of Shoulder Potholes.

From the sample results the % compliant (PS%) is determined as:

%5.96100200193% == xPS

and the 85% CL as:

%87.1200

)5.96100(5.9644.1 =−

=xx

From equation (c) the criteria for the demonstration of non-compliance becomes:

%95%37.98%87.1%5.96 >=+

In the previous example (with the same zS and ZS) the Contractor was unable to demonstrate compliance, but the Superintendent’s review has not conclusively demonstrated that the total population is non compliant. In this case a non-compliance Notice would not be issued.

Now consider if six months following the previous audit the Superintendent performs another random 200 sample inspection however as a result of this audit only 183 sections (zS) are found to have no Defects in terms of Shoulder Potholes. From the sample results the % compliant (PS%) is determined as:

%5.91100200183% == xPS

and the 85% CL as:

%84.2200

)5.91100(5.9144.1 =−

=xx

From equation (c) the criteria for the demonstration of non-compliance becomes:

%95%34.94%84.2%5.91 <=+



5 In this case the Superintendent’s review has demonstrated the total population to be non compliant and a non-compliance Notice would be issued.



5 5.4 Non-Compliance System

5.4.1 System Description

The system is based on non-compliance Notices which may be issued by the Superintendent in two forms:

a) major non-compliance Notice

b) minor non-compliance Notice

Prior to issuing a major non-compliance notice the Superintendent must present the circumstances under which the non-compliance Notice is to be issued to the Management Board.

Following such presentation the process to be followed defining the requirements for issue of the major non-compliance Notice shall be as defined by the major non-compliance issue flow-chart in Appendix A7.1.

A non-compliance Notice can only be closed by the Superintendent. The Contractor must demonstrate, to the satisfaction of the Superintendent, that the conditions required to close the non-compliance Notice have been fulfilled.

The number and status of both types of non-compliance Notice shall be reported at every meeting of the Management Board.

The issue of a non-compliance Notice shall take no account of the of the outcome of any performance deduction made in accordance with Basis of Payment Clause 3.3.

The Principal may, at its sole discretion, terminate the Contract if:

a) five major non-compliance Notices are open at any time; or

b) a Key Performance Measure for which a major non-compliance Notice has been issued in accordance with Maintenance Specification Clause 5.4.2 c) is not met within twelve months of the issue of the major non-compliance Notice; or

c) as provided for elsewhere in the Contract.

5.4.2 Major Non-Compliance

The following describes the circumstances in which a major non-compliance Notice may be issued and closed out:

a) Multiple minor non-compliance Notices



5 • Issued – at any time when a total of ten minor non-compliance Notices,

whether related or not, are open.

Following the issue of such a major non-compliance Notice, any further minor non-compliance Notices that are issued shall contribute towards another major non-compliance Notice regardless of whether any of the ten minor non-compliance Notices making up the preceding major non-compliance Notice have been closed out.

• Closed out – when all ten minor non-compliance Notices comprising the major non-compliance Notice have been closed out and the Performance Criteria to which those minor non-compliance Notices relate have been maintained for one year.

b) Failure to complete Benchmarking Surveys

• Issued – when the Contractor has failed to complete the benchmarking surveys identified within the timeframes specified in Maintenance Specification Clauses 5.2.2 and 5.2.3.

An additional major non compliance Notice may be issued for every two months a benchmarking survey has not been implemented following this issue of the initial major non compliance Notice.

• Closed out – when the Contractor has presented the results of the benchmarking survey to the Management Board, for which the initial major non compliance Notice was issued, and the Management Board has accepted the results.

c) Failure to meet Key Performance Measures

• Issued – when the Contractor has failed to meet a Key Performance Measure by a margin greater or equal to that listed in Table 5.4.1.

Separate major non compliance Notices may be issued for individual Contract Standards specified for road group/sub-groups. For example if for the Roughness – Mean NAASRA Key Performance Measure the Contract Standard is not achieved by a margin greater than the specified tolerance of 2 NAASRA for both road group 1, sub-group all and for road group 6 & 7, sub group urban the Superintendent may issue two major non compliance Notices following consultation with the Management Board.

• Closed out – when the Contractor has demonstrated to the satisfaction of the Superintendent that the Key Performance Measure has been met, sustained and verified in accordance with the close out requirements



5 identified in Table 5.4.1 and for the avoidance of doubt not merely brought back within the tolerance.

5.4.3 Minor Non-Compliance

A minor non-compliance Notice may be issued in the following circumstances:

a) Failure to meet Management Performance Measures

• Issued – when the Superintendent determines that the Contractor has failed to comply with a Management Performance Measure Contract Standard or Delivery Time.

Separate minor non-compliance Notices may be issued for each occasion of late delivery and for each instance of non compliance with the Contract Standards, for any meeting, report or management plan or for any quality control, asset management, planning, network control or communications function.

A separate minor non-compliance Notice may be issued for every month the Management Performance Measure remains in non-compliance.

• Closed out – when the Contractor’s compliance monitoring system and any audits performed by the Superintendent indicate that the Management Performance Measure is met.

b) Failure to meet Key Performance Measures

• Issued – when the Contractor has failed to meet a Key Performance Measure by a margin less than the tolerance listed in Table 5.4.2. A minor non-compliance Notice may be issued in respect of a Key Performance Measure for which a major non-compliance Notice is already open.



5 Separate minor non compliance Notices may be issued for individual Contract Standards specified for road group/sub-groups.

• Closed out – when the Contractor has demonstrated to the satisfaction of the Superintendent that the Key Performance Measure has been met, sustained and verified in accordance with the close out requirements identified in Table 5.4.2 and for the avoidance of doubt not merely brought back within the tolerance.

c) Failure to meet Operational Performance Measures

• Issued – when the Superintendent demonstrates, by inspection of the Assets, that the Contractor has failed to comply with a Contract Standard or Response Time of an Operational Performance Measure.

In the event of continuous non-compliance with respect to a Contract Standard, a separate minor non-compliance Notice relating to a particular Operational Performance Measure may be issued two months after the preceding minor non-compliance Notice relating to the same related Operational Performance Measure.

In the event of continuous non-compliance with respect to Response Time, a separate minor non-compliance Notice relating to a particular Operational Performance Measure may be issued if from the date of the proceeding minor non compliance Notice (relating to the same Operational Performance Measure) the Response Time is again exceeded prior to the Defect being rectified.

• Closed out – when the Contractor’s compliance monitoring system and any inspections performed by the Superintendent indicate that the Contractor has complied with the related Operational Performance Measure for a continuous period of six months.

d) Failure to Rectify System Failure

• Issued – when the Superintendent determines, by inspection of the Contractor’s Compliance monitoring system that a systematic correction has not been implemented to remedy a self determined non compliance.

In the event of continuous non-compliance, a separate minor non-compliance Notice relating to a particular system failure may be issued two months after the preceding minor non-compliance Notice relating to the same related systematic failure.

• Closed out – when the Contractor’s has remedied the systematic failure.
