1. Purpose

This document is intended to function as both a specification and a guideline and to ensure that all utility crossings within the railway corridor underneath or above ‘at grade’ and ‘elevated’ rail track are designed, installed, renewed and maintained to agreed standards, regulations and legislation under safe working arrangements.

This document is provided for use by government authorities, consultants, contractors and developers intending to propose or carry out work in the vicinity of the railway corridor whether it be above, below or adjacent to the corridor as defined within the Qatar Gazette notice 2014 and as contained within the MMUP policy plan for Qatar.

The aim of this document is to eliminate or reduce risks to the safety and operation of the Railway and to avoid compromising the feasibility of further future development within the railway corridor.

This document is for technical and construction guidance. Since it is not possible to cover all site conditions and scenarios in these, projects, schemes and activities have still to be examined on a case by case basis.

1.1 Background and Law

Law No. (1) of 2013 which is exempting Qatar Rail of some provisions related to the expropriation and regulation of rights over certain public and private properties, Article (5) states “The Minister shall, in coordination with the Company (Qatar Rail), issue a decision determining the Project’s Protection Zones.” The alignment has been amended under the direction of the Minister and has been officially incorporated, refer to MMUP Policy Plan No. 195080/2015 (No. 178249/2015) and subsequent following revisions.

In October 2014 the ‘Law 10 0f 2014’ was introduced in Qatar which exempts all rail activities, including activities in the Railway Protection Zones, from the jurisdiction of MMUP.

This means that Qatar Railways Company is the authorizing and permitting authority.

2. Work and Risk Management

2.1 Overall

It is important to plan, execute and control the works throughout all phases. The effort involved in

managing a risk should be commensurate with the magnitude of the risk.

The developer is expected to demonstrate to Qatar Railways Company that the risks associated

with the scheme have been identified and controlled.




2.2 Working Personnel

Competent Contractor

All works shall be carried out by a contractor or subcontractor pre-qualified, competent and

approved by the respective bodies and authorities. Proof of such qualification or approval may be

requested by Qatar Rail.

Future Railway

It may be pointed out that any 3rd

party asset located within the Critical Zone can only be accessed

by complying with special railway access requirements.

International regulations and guidelines dictate a strict control regime and state that without

appropriate technical knowledge and experience working near a live railway line cannot be

permitted.

Untrained personnel working or operating plant near a live railway will not be able to identify the

risks of working near a live railway, and will therefore not be able to recognise and avoid the

inherent dangers of the live railway, the electrified railway overhead power lines and related

threads. These personnel are termed ordinary persons.

The work within the defined Critical Zone (fence line plus 5 meters) can only be carried out by

personnel who have been trained. These personnel are termed accredited personnel.

2.3 Safe Work Method (Method Statement / Risk Assessment)

Qatar Railways Company requires the applicant to provide a method statement and risk assessment

for all works involved.

The safe work method statement (SWMS) shall provide a detailed description of the work to be

carried out. For high-risk construction work the railway organisation may require more details to be

provided.

An accompanying risk assessment is expected at task level.

A separate package describing the ‘emergency response plan’ shall be submitted to Qatar Rail. Qatar

Rail will always require sight of this, and will often wish to comment.

The process of risk assessment and control is made up of the following steps:

Identify the hazards

Assess the risk(s) to the health and safety of persons from the hazards

Use appropriate control measures to eliminate or control the risk(s)

Monitor and review the control measures to ensure on-going safety




2.4 Reporting of Accidents, Incidents and Near Misses

Qatar Railways Company requires the applicant to provide a clear description of the arrangements for reporting accidents, incidents and near misses. The applicant shall identify responsible contact persons and contact details.

2.5 Information, Instruction, Training, and Supervision

Any person which is part of the work to be carried out should have received appropriate health and safety training, instruction and on-going work related training. This becomes even more important and mandatory when working near or on a future live railway. Employers must provide appropriate supervision and should recognise their supervisor’s role in the management of the risks and the protection of employees.

2.6 Preparation for Work to Commence

Careful planning and preparation is an essential step to ensure that work is done safely. When

preparing for the commencement of work all controls indicated in the risk assessment(s) and safe

work method statement(s) must have been put in place and no new hazards exist, or have been

created.

Preparation should include:

nature of the work planned and ways of dealing with changes as the work proceeds;

assessment of effect when installing under track crossings on track settlement and determination of safe working methods;

the need to monitor any movement of other adjacent infrastructure by survey, during and after installation, and preparation of a structures monitoring plan (if applicable);

the possible hazards and risks associated with the work;

consultation with the relevant railway organisation

communication and interaction between workers on the site;

training, qualifications and competency of workers;

Checking the operation of plant and equipment, including the operation of limiting devices (i.e. slew restrictors);

proximity of persons, cranes, mobile plant, material and tools to overhead catenary lines and the railway.

specific instructions for employees;

workplace access and egress;

emergency procedures, including first aid, evacuation, and rescue; and

environmental factors




2.7 Programme of Works / Development

Risks arise where there is inadequate time to properly plan and execute the works. Qatar Rail will expect and request an initial programme to be developed at an early stage taking into account any comments from Qatar Rail. As planning, design, and work progresses, this initial programme must be further developed / updated by the applicant and transforms into an Implementation Programme. Qatar Rail shall be provided for review and comment with the latest Implementation Programme on a regular basis. This can be done by regular meetings or transmittal (as required and adequate to the work).

2.8 Notification and Permission of Commencement of Works

Qatar Rail shall be notified in due time about the commencement date and completion date of all works or activities in the Rail Protection Zone – no later than twenty-eight (28) calendar days prior commencement. The nature, type and scope of works and the program for preparation and implementation shall be clarified in detail prior to the notice of commencement. The ‘Notice of Commencement’ from the applicant shall contain a list of all previous submitted documents. Once the completeness and correctness of the ‘Notice of Commencement’ has been assessed, Qatar Rail will issue ‘Permission to Commence Work’, in writing.

2.9 Safe Working Practices

Safety management systems, procedures and working practices that identify and minimise risks to the safety, operation or maintenance of the proposed work, the railway, and persons involved, shall be developed and implemented. This is the key control measure and Qatar Rail will pay particular attention to it.

2.10 Buried Services / Services Search

A service search shall be undertaken by the applicant to identify any existing services that may be affected by the proposed installation.

The full survey shall be undertaken to ascertain the existence, location and nature of services.

The applicant shall contact all service/utility providers and obtain As-Built information.

A ‘Permit to Dig’ procedure shall be introduced and issued before excavation or driving objects into the ground.

Note that such a procedure may also be required before surcharging the ground.

Should any unknown unexpected service be discovered or uncovered, work in the vicinity of the service shall stop, ownership established, and both Qatar Railways Company and the owner of the service informed. Appropriate precautions for protection shall be taken prior to restarting work. The degree of existing protection provided to services can vary. Therefore Qatar Railways Company services shall not be interfered with or moved unless authorised by the Qatar Rail.




2.11 Request for Information (RFI)

Any request for Qatar Railways Company asset information such as structural or network information shall be made to the Qatar Rail and copied to other parties as required, who will interrogate the records database and supply an index of the data found, together with the terms for acquiring it.

2.12 Responsibility of Applicant

It is the developer’s (applicant) and utility owner’s, if delegated the designer’s or contractor’s responsibility, to obtain all data related to the proposed works including all necessary permits and to provide a fully functional and integral design. Apart from complying with this document, this includes, but is not limited to

carrying out site investigation

geotechnical investigation

topographical surveys

hydrological investigation and assessment

assessment of existing structures/building/facilities

establishing site boundaries, Railway Corridors and Rail Protection Zone’s

Obtaining utility data

coordination and agreement with all involved parties

land and property owners or leaseholders

statutory undertakers and other public services and utility owners

carrying out the works in accordance with all relevant standard, codes, regulations and guidelines

producing and distributing all relevant data before, during and after the works

2.13 Authorised and Competent Person

It is the responsibility of the developer (applicant) and utility owners, if delegated the designer or contractor, to provide people who are authorised, trained and competent to do the works. If requested by Qatar Railways Company, the applicant shall provide the relevant certification(s), where applicable ‘professionally licensed and insured’ certifications.




2.14 Communication, Co-operation and Coordination

Other Stakeholder

The contractor and/or applicant is required to fully coordinate their design and works with all relevant stakeholders that may impact works performed within the Rail Protection Zone but accepted by Qatar Rail independently. The NOC submittal shall include an acknowledgement / confirmation and/or Non-objection from the stakeholders by the ‘notifier’ that they have coordinated their works with all relevant stakeholders prior to notifying Qatar Rail and retain responsibility for this coordination and not in any way transfer risk to Qatar Rail for this coordination.

Qatar Rail

It is recommended to coordinate and discuss the proposal and all related interfaces before and during the application process with Qatar Railways Company. We recommend requesting a pre-application meeting which gives Qatar Rail the opportunity to review the draft application and provide guidance to the applicant of suggested changes and potential issues with the proposed project. This allows the applicant an opportunity to update the application prior to submittal so a better final application can be submitted which in turn reduce the number of information requests during the official review of the project. A pre-application meeting is recommended, without a pre-application meeting Qatar Rail cannot stand by its twenty-eight (28) calendar day goal for the issuance of permits. In order to have a pre-application meeting the applicant should submit an agenda and the 80% application at minimum two (2) weeks prior to the meeting with the Technical Interface team of Qatar Rail. The agenda should include:

items applicant wishes to discuss at the meeting

list of people attending

preferred meeting location

estimated meeting duration Regular communication and coordination shall be established (as required) during the construction process until the final close out of the project.

2.15 Recordkeeping

All data, records, reports, documentation, construction plans, and calculations required under this permit shall be available during normal business hours for inspection and copying by Qatar Rail, state, or local regulatory agencies and their authorized representatives, for a minimum of five (5) years from the date of recording unless otherwise required by Qatar Rail or another applicable law.

2.16 Maintenance of Utilities

It is the Utility Owner’s sole responsible for his utilities to carry out routine maintenance, renewal,

changes, adjustments, revitalization, replacement, repairs and emergency actions unless otherwise

coordinated and agreed with the Railway Company.




For any of the above mentioned activities, if within Qatar Rail Protection Zone (RPZ), the owner of

the utility has to apply for a permit from Qatar Railways Company.

For the inspection and maintenance of utilities located within the Rail Protection Zone the Utility

Owner shall submit an Inspection and Testing Plan to Qatar Railways Company.

Every owner of a utility installed under a railway or within the RPZ shall at all times maintain their

assets in good working order and condition, so that:

the safety of railway operations is not threatened in any manner;

the safety of the public, including the lives, well-being and health of people is safeguarded; and

the environment is protected

2.17 Protection of Rail Infrastructure

All work carried out on or near railway lines shall require special protective measures to be implemented to prevent damage to the rail assets. These measures shall be considered at an early stage of the work proposals and submitted with method statement/risk assessment at the time of NOC application. Where required by Qatar Rail, protective measures shall be designed, constructed, maintained and removed on completion all as directed by Qatar Rail. Protective measures shall consider the following as a minimum:

track substance;

excavation at the base (toe) of railway embankments, that might lead to destabilisation and

failure of the embankment;

excavation in the vicinity of overhead wiring structure footings as well as overhead electrical

lines (i.e. catenary lines, transmission lines);

disturbance to drainage systems over railway cuttings that might lead to failure of the cutting

slopes or fouling of the tracks below;

undercutting of the base of railway cuttings,

damage to railway drains and disturbance to the flow of storm water runoff;

damage to train examination or staff walkway areas;

excavation adjacent to building, bridges or other structures that might undermine or

destabilize the foundations;

damage to above ground railway equipment, e.g. signalling infrastructure;

damage to other existing underground services

Excavation in the vicinity of structure footings are therefore not permitted unless documented engineering advice and approval are obtained from Qatar Rail. No excavation shall be made below the base of the footings of any structure (for example bridges, retaining walls and station platforms) without prior analysis of structure stability with respect to the effects of the excavation.

2.18 Liability

The Utility Owner, its successor, or assignee shall assume all risk and liability for accidents and damages that may occur to persons or property on account of their works and actions associated




with the installation of all utility crossings, and shall indemnify and hold Qatar Rail harmless form any and all costs, liabilities, expenses, suits, judgments, comments or damages to persons or property or claims of any nature whatsoever arising out of or in connection with the approval, permit, or the operation and performance thereunder by the utility, its agents, employees or subcontractors. In this regard, it is further understood and agreed that the utility may be required to obtain insurance coverage as determined by Qatar Rail.

The Utility Owner agrees that if liability insurance is required, it will file with the designated office, prior to granting of the license, “Certificates of Insurance” or other evidence to show the appropriate insurance is carried.

The Utility Owner is responsible for any subcontractor to be knowledgeable of the guidance and to require all work to be in compliance with this guidance. Subcontractors must carry a liability policy unless the subcontractor is covered by the Utility Owner’s insurance.

A4 Inflammable substances like petroleum, oil, gas, etc. non-pressurized / pressurized

RCC, steel pipes Box culvert, portal structure preferred

3.4 Method of Construction

The installation of pipes and cables can be done by using ‘open cut’, ‘jacking’, ‘augured’,

‘directional-bored’ or ‘tunnelling’ – methods as practicable.

For utility crossings the applicant shall propose the construction method.

The method of construction should be chosen following the hierarchy:

I. All rail crossing executed prior the construction of a railway may be crossed by open cut and

sleeving methods.

II. All existing railway lines may be crossed only by trenchless crossing methods such as micro

tunnelling or horizontal directional drilling methods as approved by Qatar Rail.

III. Frame structures, box culverts or tunnels may be used for excessive loading conditions as

approved by Qatar Rail.

Depending on the particular site conditions, alternative methods for installing underground services

under tracks within the rail corridor include:

Cased auger boring: this method is suitable where precise accuracy is not crucial;

Laser-guided micro-tunnelling: this method uses a laser-guided vacuum borer head with

articulated positive steering;

Pipe jacking: pipe jacking methods are generally suitable for larger pipe diameters and can be

employed up to a distance of one hundred (100) metres. Accuracy in alignment is achieved by

using a laser beam. For jacking through non-cohesive soil where the pipe can be advanced

ahead of excavation, removal of soil in the pipe shall only proceed to within one pipe diameter

behind the leading edge of the pipe. Generally, excavation shall proceed not more than fifty

(50) mm ahead of the leading end of the pipe before the pipe is jacked forward;




Directional drilling: this process is surface launched and can be tracked down to a depth of over

one hundred (100) metres below the surface. Services can typically be laid up to a distance of

one thousand (1,000) metres in a single bore. Advantages include elimination of trenching and

associated excavation and shoring costs, greater safety, no disruptions to rail traffic and less

delays owing to unfavourable weather conditions.

Tunnel boring: this method typically employs a steel cylinder equipped with a hydraulic

excavator in the front. Extracted material is removed with an auger or conveyor and a liner

plate is installed in the rear section as the borer progresses forward. Using this method, tunnel

up to two thousand four hundred (2,400) mm in diameter can be installed in granular soil.

Trenching: trenching with rail baulks or temporary tunnelling under the tracks is permitted in

exceptional circumstances only. This method may necessitate a complete closedown of the

track.

Trenching is also permitted for services running along the rail corridor and not crossing under a

track or access road, subject to the technical requirements and review by Qatar Rail.

The following requirements shall apply to these construction methods:

Jetting under the railway will not be permitted. This does not prohibit the use of boring or

driving techniques which use water to only remove cuttings and does not permit the water to

remove material outside the designed bore dimensions. In all cases where water is used, the

discharge shall be captured and disposed of or otherwise controlled such as not to violate the

State of Qatar’s water quality regulations.

For all boring and jacking installations under main and passing tracks a geotechnical study will

need to be performed to determine the presence of granular material and/or high water table

elevation, at the sole expense of the applicant.

When unstable soil conditions exist, boring or tunnelling operations shall be conducted in such a

manner as not to be detrimental to the live railroad being crossed.

Jacking/boring pits shall be located a minimum of ten (10) metres from the nearest bridge,

culvert, track switch, building or other major structure.

If excessive voids or too large a bored hole is produced during casing or pipeline installations, or

if it is necessary to abandon a bored or tunnelled hole, prompt remedial action should be taken

by the Utility Owner.

All voids or abandoned holes caused by any kind of boring or jacking are to be filled by pressure

grouting as advised by current standards, codes, regulations.

Installation procedures and equipment details shall be submitted to Qatar Rail for review and

approval.

3.5 Geotechnical Survey

For proposed under track crossings, an assessment shall be made of the geotechnical conditions and the material through which the service is to be installed. If existing information is unavailable or is not to the satisfaction of Qatar Rail, it may be necessary to undertake testing on site by means of boreholes and trial holes, or any other applicable method.




The geotechnical conditions shall constitute one of the basic criteria to dictate the most suitable installation method.

The geotechnical assessment shall consider the effect of the proposed installation on the track, overhead wiring structures and other infrastructure, including effects form changes in the water table.

Any application by a third party (non-rail party) to install an under track crossing shall be accompanied by a geotechnical investigation / report prepared by a qualified geotechnical engineer.

The geotechnical investigation for the proposed under track crossing shall as a minimum include (but not restricted to) the following:

boreholes or test pits in regular, representative intervals along the proposed scheme;

boreholes or test pits at entry and exit points to a minimum depth of one (1) meter below the

base of the proposed excavation entry/exit points;

boreholes or test pits at the toe of the embankment;

on either side of the line to a minimum depth of one (1) meter below the base of the proposed

utility invert. For double track lines, an additional borehole or test pit shall be carried out in

between the tracks, if feasible. For multi-track lines, additional boreholes or test pits shall be

carried out as required by Qatar Rail.

For live railway lines:

These requirements are applicable only with the interruption of the traffic or very careful low velocity traffic as permitted by Qatar Rail.

The geotechnical report for the proposed under track crossing shall as a minimum included (but not be restricted to) the following: The geotechnical reports must be separated as follows:

a) the proposal of any geotechnical investigation and method statement of execution,

b) the factual report including all the results of completed investigations,

c) the geotechnical interpretive report (GIR) which include the evaluation of all the data existing

and/or additional. This report should include a recommendation for the suitable installation

method(s),

d) the Geotechnical Design Report which will include in detail all the required assumptions and

analyses to check against any predictable geotechnical risk from (subsidence during the utility

crossing construction, the long term effects coming from the installation, the stability of the

structure), the ground loading on the utility structure, etc.

e) site description and results of investigation;

f) any accurately surveyed cross section along the utility crossing alignment showing current

ground surface, rail levels (QND 95), rail positions, position of proposed utility crossing, existing

underground services, borehole or trial pit information and correlation lines of substance layers

between boreholes or trial pits, and any other relevant information;

g) prediction of possible ground subsidence during the utility crossing installation, especially if

non-cohesive soils are present;

h) recommendation for the most suitable installation method;




i) an assessment as to whether a geotechnical is required to be in attendance during construction to monitor and / or report any suspect ground conditions and / or ground movement or suspected ground anomalies to the anticipated ground conditions.

3.6 Hydrology

The applicant shall carry out a hydrology is of the movement, distribution, and quality of water in a particular area, including the hydrologic cycle, water resources and environmental watershed behaviour. Any adverse effect on the railway shall be indicated and measures shall be taken to maintain the existing system and ensure safe operation of all surrounding and related facilities and assets.

3.7 Monitoring and Site Inspection

Casings may be required for the following conditions:

a) to provide access for maintenance personal

b) as an expediency in the insertion, removal, replacement or maintenance of a carrier line crossing or other locations where it is necessary in order to avoid open trench construction

c) as protection for carrier lines from external loads or shock either during or after construction of the railway assets that mandate ‘heavy loading’ conditions

d) as a means of conveying leaking fluids or gases away from the area directly beneath the travelled way to a point of venting or drainage

e) jacked or bored installations of coated carrier lines will be contained within a casing unless assurance is provided to the railway organisation that there will be no damage to the protective coating

f) to prevent any potential settlements that may be happened in case of pipe leakage or pipe damage.

Suitable bridging, Reinforced Cement Concrete slabs (RCC) or other appropriate measures as approved by Qatar Rail shall be used to protect existing dry carriers which by reason of shallow bury or location makes them vulnerable to damage from the developer’s construction or maintenance operations. Existing dry carriers may be permitted to remain in place without further protective measures if… a) they are of adequate depth

b) they do not conflict with any Qatar Rail utility, construction or asset

c) the utility owner and Qatar Rail mutually agree that the lines can remain

d) all assets remain structurally sound and operationally safe

e) providing a future sleeve/ R.C pipe to ensure future replacement or for future use/expansion.

Existing wet carriers shall require suitable protection or diversion protection (like portal frame or secant piles with protection slab) refer to the above table. Exception: On request of the applicant and for simple configurations for dry carriers (i.e. concrete surrounding proposals) may be permitted by Qatar Rail.

4.7 Clearance to Structures

Pipelines and cable routes shall have a minimum clearance to railway structures and facilities as

follows, unless otherwise agreed with Qatar Rail. The measurement shall be taken from the closest

point between the structure and the utility.

Major rail disaster narrowly averted after two huge construction drills burst through tunnel wall

Train driver noticed water pouring down onto the roof of his train Train sent to investigate stopped just as drills penetrated tunnel ahead

Published: 20:56 GMT, 8 March 2013 | Updated: 00:51 GMT, 9 March 2013

Rail staff averted a possible major disaster today when two huge construction drills came through a tunnel wall on a major commuter route.

The driver of a train from Moorgate in London to Welwyn Garden City in Hertfordshire saw muddy water pouring on to the roof of his 10.02am First Capital Connect (FCC) train north of Old Street station.

He reported the incident and all rail services were stopped. Two construction drills came through the tunnel of the route from Moorgate to Welwyn Garden City.

A Network Rail (NR) mobile operations manager went to investigate the problem on board a special empty train from Moorgate at 11.05am.

As the train approached at low speed, two large piling drills came through the skin of the tunnel of the Moorgate to Finsbury Park Northern City line. The train stopped in time but the driver was left shaken.

The rail route, used by two million City workers every year, was closed for the incident to be investigated and for repairs to be carried out.




The incident happened north of Old Street on the Northern City line from Moorgate to Finsbury Park.

British Transport Police visited an office construction site above the line and the Rail Accident Investigation Branch were notified. FCC managing director Neal Lawson said: 'This was a serious incident that could have ended very differently had it not been for the vigilance and prompt reporting and actions of our drivers.

'We carry two million people a year on the Northern City Line and whoever is responsible for this must be held to account.

'Meanwhile, we have published details of alternative travel arrangements and are urging our passengers to check www.firstcapitalconnect.co.uk for the latest news but the line will be out of action for the rest of the day at least.'

NR said specialist tunneling contractors had been sent to the scene to assess the damage. NR route managing director Phil Verster said: 'Our engineers are on site assessing the damage and we will restore the railway as soon as possible but unfortunately the line will remain closed for the rest of the day.'

During tonight’s peak, FCC services were ran in and out of King’s Cross or Finsbury Park instead of Moorgate. Just two services had to be cancelled but six had to start from Alexandra Palace.

The line is normally closed at the weekend and engineers will be working to reopen it in time for Monday morning’s service.

Two large piling drills came through the tunnel of the Moorgate to Finsbury Park Northern City line. Read more:
