1 THE PROCUREMENT OF A CONTRACTING FIRM TO REHABILITATE AND IMPROVE THE VEHICLE MAINTENANCE WORKSHOP FOR THE CITY OF BAALBEK UNDER THE INTEGRATED SOLID WASTE MANAGEMENT FOR BAALBEK CAZA PROJECT FOR UNITED NATIONS DEVELOPMENT PROGRAMME Project Name : Integrated Solid Waste Management for Baalbek Caza Project ID : Type of Contract : Procurement of Civil Works and Goods 1. BACKGROUND Baalbek-Hermel Mohafazat includes more than 50 villages and houses more than 275,000 capita during the winter season, a value that increases to 500,000 capita during the summer season based on election population database available at the municipality of Baalbek (MEEA, 2011). The area lacks the existence of a modern sanitary landfill. The bulk of the waste generated from the different towns and villages of the Cazas of Baalbek and Hermel are disposed of in open dumps. The latter have been surveyed to count more than 50 MSW dumps (ELARD, 2011). As far as the Municipality of Baalbek is concerned and since the early 1970s, the waste generated has been dumped in the hilly Kayal site within two of the quarry sites that were exploited by the Romans as sources of stones for building their temples and monuments. The Baalbek municipality was in urgent need for a solution for its SWM issue especially with the significant amounts of additional solid waste associated with the Syrian refugees in that area. The Ministry of Environment (MoE) with UNDP undertook the preparation of a revised Master Plan for the Integrated Solid Waste Management (ISWM) in Baalbek and Hermel cazas. The Master Plan assessed the quantities of waste produced in relation to the recently increased population (because of Syrian refugees) and its composition; it also addressed the existing infrastructure of MSW collection and transport. In essence, the Master plan tackled the needs of the different elements of the ISWM facilities: 1. An existing Sorting and Composting facilities managed by the Office of the Minister of State for Administrative Reform (OMSAR) and funded by the European Union (EU); 2. An existing Biogas Production Plant executed by COSV through EU funding; 1

2 3. An Engineered sanitary landfill, in addition to such supporting facilities as administration building, a weighbridge, a control room, etc. that will constructed by OMSAR through EU funding; 4. The rehabilitation and upgrading of the secondary collection system (fleet of collection trucks, pickups, sweepers, etc.) that will be implemented by MoE through UNDP ; 5. The rehabilitation and improvement of the existing maintenance workshop, as well as other technical facilities that support the efficient operation of the MSW collection equipment. 6. The expected running cost of the various components. According to the Master Plan, the Ministry of Environment (MoE) through UNDP will be implementing the secondary collection system, in addition to the setting up of the needed infrastructure and capacity building at the municipality. One of the main scopes, and that forms the subject of this bid, is the rehabilitation and improvement of the Baalbek maintenance workshop, as well as other technical facilities that support the efficient operation of the MSW collection equipment. The direct beneficiaries of the project are the inhabitants of the caza of Baalbek, the union of municipalities of Baalbek, and the MoE. Indirect benefits will extend to the national level given that environmental benefits affect all citizens of the country. 2

3 2. EXISTING CONDITIONS OF THE PROPOSED LOCALE 2.1 Definition of the Limit of Intervention The building or locale made available by the municipality of Baalbek for future use as a maintenance workshop for the refuse collection vehicles was originally constructed as a slaughterhouse. It was, however, never being used for this purpose. Figure 1 below shows a top view snapshot of the existing building. Figure 1. The existing building In its current status, the building is being used by the municipality as a storage facility for stocking products procured by the municipality or storing items that are owned by the municipality and not being used. The existing building consists of three adjacent halls separated from each other by small corridors. Figure 2 below shows the current zoning layout of the existing building. It shall be noted that the dimensions of the various highlighted areas are indicative in nature and do not reflect the exact dimensions of each partition. 3

5 2.2 Survey of the Existing Building A topographic survey was undertaken for the zone of the existing building that will be rehabilitated and redesigned for future use as a maintenance workshop. The survey has been simplified in the form of the layout shown below which will be used throughout the report as an illustrative tool in support of the various technical descriptions. Figure 4. Baalbek workshop survey 2.3 Building Structure The main components of the existing building are made up of concrete. The frame consists of reinforced concrete columns, beams and slabs. The load bearing columns are separated from each other by approximately 5.5m as shown in Figure 5 below. The depth and nature of the building s foundations are unknown. However, considering the building height and the geological formation around the site, it was assumed that the foundations are shallow in depth. As for the interior and exterior walls, they are made of cinderblocks. 5

6 Figure 5. Different views of the Baalbek maintenance workshop hall interior The structural elements described earlier can be observed in the above photos which were taken from inside hall 1. Four rows of vertical columns as the main load bearing elements of the structure, the roof and floor slabs and the horizontal beams supporting the roof slab. As shown in the photos, the roof slab is sloped with the south western side approximately 1.25m higher than the north eastern side. It has therefore a slope of approximately 4.12 or 7.20%. This, however, does not apply to the whole building, in fact the rooms, offices, and toilets on the north western and south western sides of hall 1 have a lower and level roof at 2.93m from the floor. In general, the building structure seems to have retained its physical integrity. 6

7 2.4 Building Interior Layout Hall 1 Figure 6. Baalbek workshop survey Hall 1 Hall 1 has an area of approximately 326.7m 2 (18.06m x 18.07m). It integrates as a main feature a large u-shaped concrete workbench/workstation which consumes the bulk of the available space. Access to this hall is ensured through a door at the northern corner of the building (top left corner of the red area). The entrance is fitted with a roll down shutter. This hall has window openings on the north-western and the south-eastern walls fitted with single-glazed, hinged and sliding windows from the inside and some with a grill from the outside. The exact position and sizes of the windows can be determined from the survey. The electrical and water supply to the hall is provided through exposed electrical and water distribution networks consisting of wires and pipes along the walls (see Figure 7). In terms of finishing materials, the following is observed: - The floor consists of poured concrete; - The walls, ceiling, and columns are covered with white paint; - The workstation is covered with white ceramic tiling. In general, the finishing materials are not in good conditions. The paint is peeling due to dampness and some water leakage through the structure. This is particularly apparent on the ceiling and in some parts of the wall. Additionally, the hall is filled with clutter and unused or unwanted items which need to be removed from the site before any rehabilitation works can be initiated. 7

9 This room is used by the municipality as a storage area. With dimensions of 3.21m width and 6.06m length, it has an area of 19.45m 2. The walls are 2.84m high and do not extend to the ceiling. Accessibility to this room is assured. It has a single-glazed sliding window protected by a grill from the outside. Because this room is not directly connected to the ceiling, its walls do not show any signs of dampness. Figure 9. Interior and exterior views of Room Corridor 1 Figure 10. Baalbek workshop survey Corridor 1 Hall 1 is separated from the rest of the building by a corridor which is 1.96m wide and 15.4m long (30.18m 2 ) in dimensions. It is accessible from the eastern part of the building by a 3m wide opening in the wall. A similar opening was originally present on the wall separating Corridor 1 from 9

10 Hall 1; however this door has been condemned. Another door is available on the south-western wall (bottom of the blue area); it gives access from outside the building. As is the case with the rest of the building, the corridor is also filled with unused items that need to be removed from the site before any rehabilitation works can be initiated. Although the paint in this corridor seems in better condition than the pain in Hall 1, there are still signs of water dampness. Figure 11. Interior views of corridor Other Interior Partitions Figure 12. Baalbek workshop survey Other Interior Partitions Other components of the building, located on the north-western side of the building, include an office, an electrical room, and a room containing a fuel tank. 10

11 The existing office is currently used for administrative tasks, it contains a desk, chairs, drawers for storage and other items including, similarly to the rest of the rooms and halls in the building, clutter and unused items which need to be removed. The electrical room contains control panels and other equipment related to the buildings electrical system. The fuel tank room contains a fuel tank used for the backup generator. Similarly to the rest of the building these rooms show heavy signs of dampness, especially on the walls of the electrical room. The electrical room Figure 13.

A vehicle washing & cleaning station which will be needed to clean the refuse collection vehicles before entering the workshop and before leaving if needed. It needs to be equipped with a high pressure water jet, such as the one presented in the Figure 19 below. Figure 19. High pressure water jet b. A Storage area for the spare parts; c. An office for use by the workshop Management and administration team; d. A record keeping and archiving area. 3.2 Workshop Layout The part of the existing building which was dedicated by the Baalbek municipality for the development of a maintenance workshop was altered and redesigned to accommodate all the functions defined in the previous section. The proposed workshop layout is as illustrated in Figure 20 below. 17

18 Figure 20. Main alterations to the Baalbek workshop The layout of the workshop integrates the following main zones: Main Workshop Hall The workshop hall is where all the bulk of the vehicles maintenance works will take place and will be equipped accordingly taking into consideration such criteria as: i. Vehicle width 2.5m ii. Height clearance 4.5m iii. Pit dimensions W: 1.2m; L: 5.0m; D: 2.0m iv. Workbench / work station H: 1.2m; W: 0.9m The vehicle width and height clearance should be taken into consideration when designing traffic pathways within the workshop as well as in the design of its access points. The pit will allow workers access underneath the vehicle to perform some of the maintenance tasks such as oil changing. It should therefore be designed to comfortably fit a worker taking into consideration the width and length of the truck. The workbench has to be high enough to accommodate work while standing up and large enough to fit relatively large vehicle s parts and tools. It should also be made from durable material capable of withstanding heavy loads. Tool panels should also be fitted on the walls to keep the tools within reach of the workers. 18

19 Office The administration office will be used by the workshop management team. It will be equipped with a desk and its chair, drawers and shelves for storing and filing recent documents. It will also be equipped with a computer and a copy machine. The supply of furniture for the office is beyond the scope of the workshop rehabilitation. Storage and Archiving Area A storage area will be dedicated for the storage of the spare parts. A part of that area will be equipped with storage cabinets suitable for storing documents over a long period of time and protecting them against dust and moisture. The supply of such cabinets along with any shelves that might be needed for the storage of the spare parts is beyond the scope of the workshop rehabilitation. Wash Station A washing station dedicated for washing the vehicles will be introduced. 3.3 Brief Description of the Anticipated Planned works The planned rehabilitation works consist of either alterations of specific components of the existing building or addition of new components. The bulk of the rehabilitation works fall under civil and structural works. As for the mechanical, electrical and plumbing systems, they already exist. Limited works are needed. A brief description of the anticipated works is presented in the Table 2 below. Further details are comprehensively elaborated in the drawings included in the volume II of the Tender Documents. The technical specifications and the corresponding price schedules of the works are provided in volumes III and Section 7 respectively. It is highly recommended that bidders visit the site to familiarize themselves with the existing conditions. 19
