Ramp-Up-North Project
Regional Afghan Municipalities Program for Urban Populations (RAMP UP) is to createeffective, responsive, democratic, transparent, and accountable municipalgovernance in the nine provinces that comprise the International Security Assistance
Forces (ISAFs) Regional Command North.
RAMP UP North (RU-N) will:
1. increase the capacity of the Government of the Islamic Republic ofAfghanistan (GIRoA) municipal officials,
2. markedly improve the delivery of municipal services to citizens in targetmunicipalities, and
3. Increase municipal capacity to enable, support, and sustain economic growth.As a result of the RAMP UP North project, Afghan citizens will receive betterservices, understand the responsibilities of municipal leaders, play an active
role in the municipal decision-making process, and see local governancestructures as legitimate.
SAR-E-PUL Post Flood Assistance Subproject
On May 19, 2012 in Sar-e-Pul city, flash floods triggered by torrential rains gave wayto forceful flood water rising to a height of nearly five meters (16 feet), damaging thecitys main flood protection and retaining wall, located just about six kilometers (justunder 4 miles) from the city center, causing the destruction of many of the citysinfrastructure systems inclduing roads, bridges, canals and houses. The flood,reportedly the worst in 80 years, killed 22 people.
The Municipality government of the city conducted a flood damage assessment and
made a request to USAID/RU-N to investigate the ecological impact of this. RU-Nengineers liaised with the Municipality and together developed a rehabilitation planto build back better and improve the following infrastructure:
1. Irrigation Canal running through the city
2. Gravel road streets and roadside ditches
3. Street box culverts
4. Pedestrain concrete footbridge
5. Vehicle bridge
Also under consideration was the building of the capacity of the Municipalitysconstruction department through staffing, supplies and training programs.
B. Subproject Overview
Identification
Based on a review of this rahabilitation plan, the activities designed forreconstruction works under this subproject shall include the following:

1) The cleaning and dredging of the citys main canal and reconstruction ofdamaged sections of stone masonry canal linings and canal intake walls
2) The repairs of 6 kilometers of existing gravel roads
3)The repairs of 10-20 box culverts along the roads or streets of the city
4) The reconstruction of destroyed pedestrain footbrdige
5) The reconstruction of destroyed vehicle bridge
6) The provision of capacity building and technical assistance activities
Legal, Regulatory and Permitting requirements
All legal, regulatory and permitting requirements for this subproject have beenquestioned, obtained and approved. See Appendix 1.0.
Based on the information and data gathered, the subproject feasibity and risks, scopeof work for design and construction as well as claims, change, and documentationshave been identified and evlauted. See Appendix 1.0.
This subproject did not procure design services as the size and complexities of theinfrastructure under the subproject is small to medium in size; sufficient enough touse the expertise of RU-N in-house engineering deprtment and the technicalassistance of the Sar-e-Pul Municipality/MRRD/NABDP-North.
However, to determine the question of design liability it would have been moreeffective to hire the services of a design firm as well as an independent design reviewservice provider. On the other hand this would have been a bit complicated owing to
the fact that the design firm, in oder to be held liable for design defects or failures,would have had to be given full management authority of the subproject sites andchange and reject orders to all works performed within the limits of the designs,thereby putting the role of DAI/RU-N engineering team as only site monitors.
Project staff
The subproject staffing has been organizaed to include the following personnel:
Project Management Capacity Building Advisor
Public Works Advisor
GIS Specialist
Hydrologist
Engineers Engineering Clerk
Subproject Level Risk Screening
After the review of the results of the legal and regulatory survey for infrastructure,the subproject level risk screening was conducted and the subproject risk wasestimated to be very significant and required a risk mitigation plan.

After the screening, the subproject activities are anticipated to include the following:
1) The cleaning and dredging of 19.6 kilometers of the existing canal andreconstruction of 50 meters of stone masonry canal linings and 12 metersreinforced concrete canal intake wall.The scope was modified to include only30m of stone masonry canal lining because 30m of the lining repairs was done
by another agency UNODC.
2) The repairs/resurfacing of 2.6 kilometers of existing gravel roads including2640 meters roadside ditches and construction of eight (8) units of RCC boxculverts
3) The reconstruction of 44.5 meters of stone masonry canal linings orretaining/protection wall near the footibridge
4) The reconstruction of a 20 meters span pedestrain reinforced concretefootbrdige
5) The reconstruction of a 16 meters span reinforced concrete vehicle bridge
6) The construction inspection and testings of structural components of theabove activities
7) The provision of capapcity building and technical assistance to theConstruction Department of the Sar-e-Pul Municipality
The DAI/RU-N engineering team provided the design and construction plans for thecanal, roads, and culverts respectively, and the Sar-e-Pul Municipality through theMRRD/NABDP-North provided the design and construction plans for the flood wall,footbridge and vehicle bridge respectively. DAI/RU-N will provide capacity buildingtraining including project management and construction management under thissubproject to Sar-e-Pul Municipality engineering department.
See Appendix 3.0 for the Subproject Level Risk Screening Form and Risk Register.
The construction is scheduled for six months beginning July 2012 and endingDecember 2012, which is unrealistic owing to the fact that in Sar-e-Pul the wintercomes in early December reducing all possibilities of conducting construction works,such as pouring concrete (a major component for all activities), which requires theconcrete remain in the formworks for at least 28 days to properly cure and obtain fullstructural intergrity, and ends early March, thereby actually requiring the subprojectduration to be from July 2012 to June 2013 (approximately 12 months) .
The subproject delivery strategy shall be to procure the construction services in a
design-bid-build approach with Sar-e-Pul Municiaplity serving as infrastructure owner,technical support team and facilitator/coordinator, RU-N serving as overallconstruction manager and private construction company(s) serving as constructionservice providers.
The anticipated social, public and environmental issues have been identified andmitigated against after conducting an environmental screening of all activities underthis subproject. See Appendix 2.0 for Environmental Screening Checklist andMitigation Measures Plan

Design Studies and Research
To carry out the execution procedures and manage this subproject infrastructure,various design studies and research options were reviewed and evaluated to considerthe design options that will define or influence the nature and extent of the ultimate
design for reconstruction of the infrastructure under the subproject.
Most of the design studies avalaible were obtained and made part of the scope ofwork required by the RU-N engineering department to form part of the final designdocuments before award of construction services.
The infrastructure owner, Sar-e-Pul Municipality, through the MRRD/NABDP provideddesigns and design review for the rcc footbridge, flood wall and rcc vehicle bridge,because of their complexities, whereas, the canal dredging and linings and roads andculverts have been design by RU-N and reviewed by the engineering director andproject management capapcity building advisor of RU-N.
After a review of the various surveys and research data available from USAID, theGIRoAs Ministries of Rural Rehabilitation and Development, Public Works andAgriculture, Sar-e-Pul Municipality, and the various implementing partners inAfghanistan, the following types of possible design studies have been considered:

Environmental Mitigation and Local Environmental Law:
An environmental screening was conducted and all issues and concerns andassociated mitigation measures thereof have been compiled and approved. SeeAppendix 2.0 for Environmental Screening Checklist and Mitigation Measures Plan.
Social Issues:
All stakeholders have been identified (Sar-e-Pul Municipality government infrastructure owner) and all other social issues have been included in the mitigationand monitoring plan. See Appendix 2.0 for Environmental Screening Checklist andMitigation Measures Plan.
Coordination with Infrastructure Owner:
The Sar-e-Pul Municipality owns all infrastructures under the subproject and there areno conflict concepts of the ownership. The works are coordinated with theinfrastructure owner, who supports the subproject concept, design and operationsrequirements.
However, the infrastructure owner does not have the capacity (personnel andbudget) to maintain and operate the infrastructures after the subproject is handedover; or the means to decommission the infrastructures after its useful life iscompleted.
It is also not clear if coordinating donors or the provincial government will providethis assistance. However, RUN will provide project management and constructionmanagement capacity building training to personnel available in the municipality soas to ensure some amount of sustainability can take the life span of theinfrastructures to not less than 15 years.
Technical Considerations:
It is agreed the infrastructure owner will be required to carry out the followingresponsibilities:
Agree in writing with Confirmation Scope of Works
Agree with technical design by way of signing technical design and coveringall design liabilities
Attend inspections and sign certificates and punchlists, etc.
Sign handover document and take ownership of the property whenconstruction is complete
The infrastructures are priority subproject in the Sar-e-Pul city municipality masterplans, and the need-to-rebuild analysis has been completed. The existing sites are
appropriate for the infrastructures; the solution best-fit for the identified problems;the needs independently verified; the estimated impact and beneficiaries verified;the requirements clearly defined and analyzed and are realistic; and the functionalrequirements and users acceptance criteria verified.
The subprojects costs and schedule limits have been defined, agreed to anddocumented. There are no significant data missing.

After conducting a subproject level risk screening (see Appendix 3.0) the subprojectactivities are considered very significant but not high-risk. A risk register (seeAppendix 4.0) has been developed and mitigation measures and monitoring plans inplace to manage and response effectively to identified and new risks respectively.
Sustainability:
The infrastructure under this subproject plays a massive role in Sar-e-Pul city and
helps support the peoples way of life, and the world around them, both the natural
environment and communities, increasing the need for sustainability more important
to individuals, organisations, communities and the government. Given the scale and
impact of the infrastructure and the physical assets involved there is a real need for
sustainability to become part of the way the citys physical asset operates.
In order to achieve real sustainability in this subproject infrastructure and assets, it is
necessary to incorporate sustainability (economic, social, environment) with
associated measures, metrics and indicators, across all of the key areas and at allphases of a subproject's or asset's life.
Therefore in designing and planning for construction for the activities under thissubproject, the following parameters have been considered and incorporated into thedesign and construction plans of the subproject and infrastructure:
Management & Governance - management systems , procurement & purchasing ,
climate change adaptation
Resources - energy & carbon, water, materials
Emissions, Pollution & Waste - discharges (into the air, land & water), land (usage,
conditioning etc), waste
Ecology - functional level and state of ecosystems, biodiversity
People & Places community health, well being & safety, natural & cultural
heritage, stakeholder participation, urban & landscape design
Innovation - pioneering initiatives, methods, processes, procedures, technologies
etc that assist market transforming towards a more sustainable approach.
The goals for activity sustainability has been defined and measured and areachievable. The plans to meet and optimize these goals have been developed
through a capacity building training program for the municipalitys engineeringdepartment.
Design Professional
There exist in Afghanistan no system of licensure and registration for engineeringand design professionals. However, because of the size and technicalities of thissubproject, the design and construction is corroborated with the Sar-e-PulMunicipality and its technical support team from the Ministry of Rural Rehabilitation

and Development National Area Based Development Program North. Sar-e-PulMunicipality will take professional and design liability coverage for the subproject.
Construction & Construction Management
There are available experienced local constructors for construction of this subproject.
However the Defense Based Act insurance is not required. Notwithstanding, allbidding offerers and/or subcontractors are required to provide the necessaryinsurance and their failure to do so can result in possible loss of their subcontract.
Local constructors will not require training to effectively bid on this subproject.However, all required site-specific queries and conditions applicable to specifications,etc. has been clarified in the RFPs and pre-bid site conferences.
RU-N engineers (Site Inspectors) will be responsible for construction inspection dailyon behalf of the project. All site locations are stable; all sites are open access, and onsite activities can be monitored regularly.
The equipment to use will be tested for design standard and specificationcompliance; and the constructor will be required to adhere to all site health andsafety requirements stipulated in the subcontract.
There is no sufficient time to complete the subproject infrastructure constructionworks, as there is approximatley 2-3 months of heavy winters (December-February)that will possibly halt all site construction activities. There will also not be enoughtime to accommodate winter period and restart and complete and closeoutafterwards, as the project is for only six months beginning July and ending December2012. However, there could be a realistic possibility for no-cost extension to thisactivity.
Quality Assurance & Quality Control:
There is adequate capacity and resources in the province and region respectively toassure quality of the subproject activity. An independent testing agency will beresponsible for all quality control.
The design and construction services for this subproject can be procured within thecurrently approved project code.
The subproject complies with the clients requirements for feasibility studies,research and reviews. DAI/RU-N has put in place a quality management plan thatfocuses on the following:

IBC (International Building Code) for safety, structural, and fire and life safetyprovisions covering seismic engineering provisions, innovative constructiontechnology, and the latest industry standards in material design
NAISC (North American Industrial Classification System) for Dredging (e.g.,canal, channel, ditch, waterway)
Activity Infrastructure Design
The canal underwent an accelerated eutrophication due to the flash flooding in June2012. Therefore there was an increase in vegetation, which had not been removedover the years. And now that the canal is to undergo mechanical dredging andcontruction works there will be more disturbances to the canal flow and water levelcontrols.
Based on the intended purpose of this activity, the general design critiera includingminimum loads, flows or volumes, dimensions, capacities and sizes have beenconsidered and developed. The design consideration includes the following:
1) Potential Environmental Impacts and Mitigation Measures
Location of construction camps
erosion and sedimentation control conditions
situation of fuel storage, refuelling and machinery maintenance
dust prevention
construction waste and debris management
health, safety and public protection measures
nuisance and other inconvenience Issues
monitoring
1) Permits and Legal considerations
permits obtain by the infrastructure owner/Sar-e-Pul Municipality
disposal of dredge materials indicated by the Sar-e-Pul municipalty

Overall depth allowances
Designed overdepth
Mandatory maximum dredged depth
5) Overwidth dredging considerations
dredging to excess width to provide advance maintenance to compensatefor silting or sloughing of side slopes
Profitability use of dredging materials for landfills, etc
Environmental considerations including control of discharge, control ofdisturbed sediment in dredged area, and polluted sediments
6) Dredging methods
Selection of method (mechanical or manual) based on capacity anddepth considering the character of materials to be handled, weight, andcohesion; and loadings on the barge and their effect on stability andstructural strength.
7) Canal Linings
efficient use of land and water resources
type of strata
conveyance of water, uniform flow and control of seepage
surface type and resistance and command area and optimal section ofthe canal
average velocities, existing slope conditions
cost structure
8) Canal Intake
overall hydrologic, environmental, geotechnical and economic factors
water availability
bathymetry and sediment transport
environmental regulations and climatic conditions
constructability and initial and maintenance dredging requirements
operation and maintenance
Based on the listed design considerations, the following scope of works wasdeveloped:
1. Use of manpower (skilled and unskilled) to remove floating organic materials, etcfrom the canl linings, slopes and water to achieve maximum allowable flow andcontrol
2. Use of machineries (excavator, loader, dump trucks) to remove sediments andmud from canal floor to improve water floor and water level efficiency to achieveoverall depth and width allowances
17

3. Use of machineries and skilled and unskilled manpower to demolish and removedamaged canal linings and intake walls and reconstruct stone masonry linings andreinforced concrete intake respectively to ensure water is conveyed uniformlywithout seepage, etc.
4. The works is designed to be completed within 60 (sixty) working days including 30
(thirty) days for manual works and 60 (sixty) days for mechanical dredging andreconstruction works
The technical designs were developed and reviewed and approved by theinfrastructure owner (Municipality authorities of Sar-e-Pul). See Appendix 5.0 forDesign Review Log.
Construction permit for the design and construction of the subproject has beengranted or authorized by the appropriate permitting authorities.
The canal dredging and protection walls subproject design has been thoroughlyreviewed with several feedbacks provided by the infrastructure owner and projectclient. The infrastructure owner and project client have approved the subproject
activity documents.
Activity Construction and Construction Management
The procurement strategy and solicitation type and method was discussed with theGrant, Subcontract and Compliance Manager and approved by the COP. Technicalspecifications and requirements, including estimates, are complete, accurate, andrealistic. The design and bidding information respectively are well defined andrealistic enough for bidders to prepare realistic and responsible technical and costproposals.
Considering the options appropriate for the construction of this subproject, theacquisition strategy applied is the Design-Bid-Build (DBB) delivery method. This canal
dredging and construction subcontract type shall be Firm Fixed-Price Purchase Order.This strategy outlines the fitting risk sharing, incentives for performance, and reducespotential cost overruns, etc. The selection method is sealed bidding and the lowestprice technically acceptable.
The private sector has the capacity for understanding the requirements, estimatingcost and times, handling the value of procurement envisaged, and managing within afirm fixed price subcontract agreement.
The procurement officer has been supported with the requisition process. The noticesfor solicitation have been released, bid evaluation committee established and bidsreceived, opened and evlauted and offerer selected for subcontract. The Subcontracthas been signed and pre-construction conference and kickoff completed and the
subcontractor issued the Notice to Proceed.
Construction had to be delayed for 10 days due to the construction of one section ofthe works (20m stone masonry canal lining) by another contractor from anotherpartner (UNODC). It has been difficult to determine where the fault for this originated,but it has been concluded that due to defaults in field coordination between the Sar-e-Pul Governor and Mayor and RU-Ns Municipality team may be the reason thereoffor this setback. However, the problem was resolved by reducing this portion ofworks from within the total value and scope of works of RU-N Sub-contractor for thisactivity.

Activity Infrastructure Design
During the flood in Sar-e-Pul city gravel roads absorbed so much water on the steepparts and the road camber to shed water become poor, allowing water to remain onthe road, creating maximum potential for damage from washouts. This water causedincreased damage all along the roadway.
Also the roads were easier to damage because of the long absence of gradingthereby becoming steep, creating no flow of water from the roads. Coupled with this,vehicles caused movement of gravels due to braking and wheel spinning action.
Based on the intended purpose of this activity, the general design critiera, the trafficloads and volumes, driving surface crowning, shoulder area slopes direction, drivingsurface edges, ditch, capacities and basic shape of the cross section, and seives forgrade, sub-base, base and surface aggregate have been considered and developed.
The design consideration includes the following:
1) Potential Environmental Impacts and Mitigation Measures
Location of construction camps
erosion and sedimentation control conditions
drainage features

Activity Identification:
During the initial assessment no flood wall was considered as the flow control ofthe stream was considered satisfactory with no harm to the footbridge.However, after another assessment by the Sar-e-Pul tevhnical support teamfrom MRRD/NABDP-North, it was observed that soil near and around theexisting proposed wing wall of the proposed footbridge would overtime becomeunstable by any increase in the water flow and level and would thereforebecome an active force to the footbridge wing wall. To resolve this there isrequired the construction of a wall to retain the soil and also control the waterflow from flowing behind the wing wall of the footbridge.
The flood/retaining wall will be located near the proposed reinforced concretefootbridge in Chamray, Sar-e-Pul city.
The wall shall be 44.5 meters long and 8m high. It shall be constructed usingunskilled workers at the following location:

Based on the listed construction inspection and test considerations, the followingscope of works was developed:
1. The inspection of slump test procedures, processes and specimen for roads,side ditch and culverts rehabilitation Works, footbridge reconstruction works,flood Protection wall reconstruction works and vehicle bridge constructionworks
2. The implementation of field and laboratory test, and recording and reportingfor roads, side ditch and culverts rehabilitation Works, footbridgereconstruction works, flood Protection wall reconstruction works and vehiclebridge construction works
The technical spcifications were developed by DAI/RU-N engineering department andreviwed by DAI/RU-N engineering director and project management capacity buildingadvisor respectively, and approved by the infrastructure owner (Municipalityauthorities of Sar-e-Pul). See Appenmdix 5.0 for design Review Log.
Permit to conduct construction inspection and test of the subproject infrastructureshas been granted or authorized by the appropriate permitting authorities.
The construction inspection and test procedures, processes and specifications andstandards have been thoroughly reviewed with several feedbacks provided by theinfrastructure owner and project client. The subproject activity documents have been
approved by the infrastructure owner and project client.
Activity Construction and Construction Management
The procurement strategy and solicitation type and method was discussed with theGrant, Subcontract and Compliance Manager and approved by the COP. Technicalspecifications and requirements, including estimates, are complete, accurate, andrealistic. The design and bidding information respectively are well defined andrealistic enough for bidders to prepare realistic and responsible technical and costproposals.
Considering the options appropriate for the construction of this subproject, theacquisition strategy applied is the Design-Bid-Build (DBB) delivery method. This
construction inspection and testting subcontract type shall be Unit Price paymentPurchase Order. This strategy outlines the fitting risk sharing, incentives forperformance, and reduces potential cost overruns, etc. The selection method issealed bidding and the lowest price technically acceptable.
The private sector has the capacity for understanding the requirements, estimatingcost and times, handling the value of procurement envisaged, and managing within afirm fixed price subcontract agreement.

7/29/2019 1. Sar-PFA Infrastructure Management Report
51/59
In an attempt to test DAIs draft infrastructure management manual (IMM) the Sar-e-Pul Post flood Assistance Subproject implemented by DAI/RU-N program applied themanuals phases, procedures, work instructions, and forms and template todetermeine its workability and value especially for infrastructure field work carriedout by the organization.
Overall the manula has been useful, but its lack of basic engineering considerationsfor design, estimation and construction applications, yet understandable as DAI is notan infrastrure design and construction company, still lacks the provisions such asquality management and change management, core to engineering management,and its integration with professional project management practives.Having considered this, it is also important to note that much assistance did comefrom the grant, subcontract and compliance department as well as the programdepartment, suffocient enough to support, assist and guide the infrastructuremanagement department in project management.
During the implementation of this subproject the key issues was about quality and
change management, which the manual does not address, but must be providedunder a coaching or training program continuously in project life time to enable theengineers managing infrastructure subprojects to effectively manage cost, time,resources, risk and quality in an integrated subproject life cycle managementapproach.
The IMM is basic and valuable in providing immediate impact of engineers inunderstanding the fundamentals of managing infrastructure subprojects, not onlyunder DAI, but anywhere else required. The manual provides the guidance andpractical applications suitable to construction management and project managementfor such architecture, engineering and construction activities.
