1. INTRODUCTIONThe UNDP Tsunami Recovery Waste Management Programme (TRWMP) is tendering up tofive contracts for construction services for various TRWMP supported solid wastemanagement engineered landfill facilities in Aceh Province, and Nias Island, NorthSumatra Province, which are summarised as follows:• Construction of up to four district landfills in Aceh from the following list of eightshortlisted sites:o Sabang island - Lok Batee (LB);o Pidie - Cot Padang Lila, km23 (CPL);o Lhokseumawe/Aceh Utara - Alue Alim 1 & 2 (AA); ando Bireuen – Cot Bukeet (CB)o Aceh Jaya - Lhok Bot, Calang;o Aceh Barat- Pasie Aceh;o Nagan Raya- Alue Le; ando Simeulue Island - Suak Buluh.• Construction of one district landfill in Gunung Sitoli, Nias.This TOR details the services required and the scope of works, in order to allowprospective bidders to prequalify for the future tender for works. The document isorganised as follows:• Section 2 provides background information on the TRWMP and prior works completedfor the waste management facilities listed above.• Section 3 details the scope of works required from the Construction Contractor.2. BACKGROUND2.1 UNDP’S TSUNAMI WASTE MANAGEMENT PROGRAMME (TRWMP)The Tsunami Recovery Waste Management Programme (TRWMP) was conceived to provide acoordinated, pragmatic response to the public health and environmental concerns associatedwith both tsunami/earthquake debris and municipal solid waste (MSW) management duringthe rehabilitation and recovery of Aceh and Nias following the 2004 earthquake and tsunami.The short term aims of debris clearance and creating immediate temporary employment havelargely been completed and are now superseded by the longer term goals of buildingcapacity in government and developing sustainable waste management systems that willbenefit the environment through the collection, recovery, recycling and/or safe disposal ofMSW whilst incorporating cost recovery through the promotion of waste managementrelatedlivelihoods. This shift in focus is reflected, in the PADII and PADII.2 (Available uponrequest) documents, through the revised Programme Development Objective (PDO):‘To improve and sustain the environment of Aceh and Nias through; (a) strengthening thecapacity of local government to conduct effective efficient collection, recovery and disposalof municipal and tsunami waste; (b) rehabilitation of critical waste managementinfrastructure; and (c) supporting local enterprises in the creation of livelihoodsopportunities in recovery, processing and recycling of waste, and clearance andrehabilitation of tsunami impacted agricultural land.’27


The TRWMP commenced operation in March 2005 and is being executed by the UnitedNations Development Programme (UNDP) through the Aceh Emergency Response andTransitional Recovery (ERTR) Programme in partnership with the Rehabilitation andReconstruction Agency (Badan Rehabilitasi dan Rekonstruksi - BRR) and is currently beingimplemented through partnership with local government sanitation departments in thirteendistricts including Kota Banda Aceh, Aceh Barat, Nagan Raya, Pidie, Aceh Jaya, Aceh Besar, Niasand Nias Selatan, Lhokseumawe, Aceh Utara, Bireuen, Sabang, and Simeulue.ObjectivesIn September 2010 the MDF approved an extension to the TRWMP for Phase III which willextend the Programme up to June 2012. The TRWMP extension has been designed to achievethe following objectives in line with the revised PDO given above:1) To provide government with financial and technical support to continue to build capacity,clear residual tsunami waste in rural areas, complete the development of sustainablemunicipal waste management systems and expand the geographic coverage to otherdistricts in Aceh.2) To promote waste management livelihoods so that the economic benefits from recyclingare derived in NAD-Nias and minimise the waste volume going to landfills.3) The detailed evaluation, design and construction supervision of permanent districtlandfills, including a regional sanitary landfill facility for KBA/ Aceh Besar, with BRR toprovide funds for construction.4) Effective and efficient management, monitoring and oversight of the overall programmeon behalf of the MDF donor partners.This Prequalification concerns part of Component 3 above covering the construction of fourdistrict landfills in Aceh, and one landfill in Nias.2.2 STRATEGY FOR DEVELOPMENT OF PERMANENT DISPOSAL FACILITIESPrior to the tsunami, disposal of MSW was simply down a hillside, into rivers or the sea or, atbest, in open dumpsites, often located in close proximity to residential areas or the coast, withlittle or no environmental controls, presenting hazards to both public health and theenvironment. Some sites were also directly impacted by the tsunami (e.g. Gampong Jawa inKBA, and Sigli). The Master Plan for the rehabilitation of Aceh recognized that coastal sitesshould be relocated and environmental controls improved. In the 2-3 years before newsanitary landfills could be constructed there was an urgent need to provide interim facilities toaccept MSW and residual tsunami-derived wastes in a manner that would not significantlyimpact the environment. The project included a 2 stage rehabilitation of Gampong Jawadumpsite in Banda Aceh, with an interim landfill expansion suitable to provide storagecapacity until the new regional landfill at Blang Bintang was completed. An additional 10emergency/ temporary engineered landfills have been constructed. These facilities havelimited lifespans (6 months to 2 years) and new permanent facilities are required if a return tothe former unsanitary practices is to be prevented. The need for new, permanent, sanitarylandfill facilities is also reinforced by the new GoI Waste Management Law uu18, 2008, whichspecifies that all open dumps should have a plan for closure or upgrade to sanitary landfillstatus within one year, and this plan must be executed within five years. Whilst governmentpartners have received on the job training in landfill construction and operation, they remain28


dependent on TRWMP support in many districts and more training is required prior to TRWMPexit.Where long term feasibility and sustainability can be justified, the programme aims to providelong term solutions to waste recycling through the livelihoods programme and waste disposalvia permanent (15+ yrs) district or regional landfills, well designed to minimise operationalcosts and environmental impact.The intent is for UNDP to use its comparative advantage in all the districts in which it operatesto supervise the feasibility and design of permanent facilities in all districts. Whilst chargingfor waste collection may be required to subsidise operation of larger facilities, the smaller sitesare expected to be operated without fees provided the district governments can secure theirbudget entitlement. The feasibility of the use of the clean development mechanism (CDM) togenerate Certified Emissions Reductions (CERs) or carbon credits to subsidise operation is alsoto be considered.The TRWMP exit strategy can be considered complete once government partners cansustainably operate the adopted waste management systems without TRWMP support(estimated 6 months from start of operation of new landfills), have all facilities and equipmentrequired, and have secured sufficient budget from the district/provincial government tooperate and maintain the system.2.3 LOCATIONS OF TRWMP ACTIVITIESThe Tsunami Recovery Waste Management Programme covers thirteen districts, selected onthe basis that they were most heavily impacted by the tsunami/ earthquakes; Kota Banda Aceh(KBA), Aceh Barat, Nagan Raya, Pidie, Aceh Jaya, Aceh Besar, Bireuen, Lhokseumawe, Aceh Utara,Sabang, Simeulue, Nias & Nias Selantan. Letters of Agreement (LoAs) with the districtgovernments provide for technical support from UNDP and funds for administrative staff,temporary workers and operating equipment/ supplies. (See Figure 1.

2.4 BACKGROUND TO THE DEVELOPMENT OF DISTRICT LANDFILLSBackground information and studiesAs part of the TRWMP programme for permanent sanitary landfill developments across the thirteenprogramme districts, TRWMP commissioned Meinhardt (2008-9) to conduct evaluation, site search, prefeasibilitystudies and concept designs for 12 sites.The studies outline the district waste management strategies for the next 15 years, and providesconceptual designs for the new sanitary landfills including preliminary drawings. These documents areto form a starting point for the consultant in developing landfill options and detailed engineeringdesigns, however, assumptions or standards based on these studies alone without further study orverification will not absolve the design consultant of responsibility for design decisions.Details of the information available from this work is given in Table 1.0. TRWMP sought funding fromthe MDF to complete the design and construction of sanitary landfills across all districts, whererequired. However due to funding constraints the number of landfills moving forward to the next stepof Detailed Engineering Design has been reduced to ten (including Blang Bintang and Nias), See Table2.0. TRWMP will seek counterpart government funding to complement the available MDF funding,ensuring government buy-in and enabling as many of the shortlisted ten sites to be constructed aspossible. TRWMP consultants are completing Detailed Engineering Designs (DEDs), including technicalspecifications, and bill of quantities (BOQs), sufficient to go to tender for construction for the remainingeight district sites on the shortlist. These consultancy contracts also include construction supervisionfor five of the landfills (Nias Island, Teluk Belukar (TB), Sabang Island - Lok Batee (LB); Pidie - Cot PadangLila, km23 (CPL); Lhokseumawe/Aceh Utara - Alue Alim 1 & 2 (AA); Bireuen – Cot Bukeet (CB)) wheregovernment counterpart funding has already been obtained.TRWMP has had a longstanding working relationship with the district government sanitationdepartments (Dinas Kebersihans), formalized through Letters of Agreement (LOAs). Post disaster,TRWMP provided assistance to Dinas’ with clearing tsunami and earthquake waste, and restarting solidwaste management services by providing O&M assistance and constructing interim engineeredlandfills. TRWMP is now providing long term training and capacity building assistance and,infrastructure support through the construction of long term sanitary landfills in selected districts. Thedistrict Dinas staff have been involved in every stage of the site search and planning process for thenew sanitary landfills. They will also be involved, as the client and ultimate beneficiary, in the decisionmaking process for the detailed engineering designs and construction supervision. District staff will beexpected to form a ‘shadow construction supervision team’ (the Shadow team). The Shadow team willconsist of Dinas staff members selected for their technical qualifications and experience, and directfuture involvement in the landfill operation and extension. The Shadow team will work alongside theConstruction Supervision Consultant (CSC) team, leaning from them the important aspects ofsupervision, quality assurance, construction methodologies and operation and maintenance. TheShadow team will have the authority to jointly sign off works with the guidance of the CSC team, butwill not have the right to stop or amend the works, or in any way direct the construction contractor.31
