Terms of Reference (TOR)
1. Project Objectives
The construction of the Koh Tao Community Waste Management Center (Waste Bank) is executed under the support of the MA-RE-DESIGN project with the primary objective of promoting marine and coastal conservation through the following:
- To support the goal of reducing the volume of plastic and solid waste leaking into the marine and coastal ecosystems surrounding Koh Tao.
- To develop a Circular Economy by constructing standardized infrastructure for comprehensive waste management.
- To accommodate and promote the Extended Producer Responsibility (EPR) mechanism via a practical reverse logistics system on the island.
- To serve as a sustainable waste management learning center on Koh Tao, providing opportunities for the community and various organizations to visit and study its operations.
2. Scope of Work and Construction Details (Minimum Requirements)
The contractor shall design and construct the facility/usable areas with the following minimum sizes and engineering specifications:
2.1 Site Preparation & Grading
- As the actual construction site is situated on a hillside, the contractor must conduct on-site surveys and assess the necessary land grading (Cut and Fill) to achieve a level ground surface that is stable, strong, and safe enough to support the building structure, operational yard, and heavy truck traffic.
2.2 Front Office & Reception
- Office: A minimum area of 12 sq.m. to accommodate two employee workstations and a customer reception seating area.
- Shop Area: A minimum area of 9 sq.m. for product display shelves.
- Learning Center / Multipurpose Room: A minimum area of 16 sq.m.
- Architectural Requirements: The wall adjacent to the “Sorting Area” must utilize extra-wide folding or sliding doors (using a top-hung or flush track system to prevent tripping hazards) to allow the space to be opened widely, providing flexibility for large groups of visitors and allowing carts to pass through smoothly.
2.3 Operations & Sorting Area
- Waste Sorting Area: An open, spacious area utilizing a Heavy-Duty Concrete Floor (reinforced concrete), designed to allow forklifts to enter, exit, and operate safely without subsiding or cracking.
- Waste Baler Area: A designated space for installing 1 waste baler machine, requiring a Vibration-Damping Foundation, along with dedicated electrical connections and a separate breaker appropriately sized for the machinery.
- Packaging Management Area: A designated space for installing a packaging washing machine, including an area for storing cleaned and ready-to-use packaging.
2.4 Storage & Support Area
- General Storage: A minimum area of 9 sq.m.
- Indoor Waste Storage (Sorted/Baled): An indoor storage space that is well-ventilated to prevent musty odors.
- Restrooms: A total of 3 rooms, categorized as follows:
- 1 Female restroom
- 1 Male restroom
- 1 Staff restroom (which must include a dedicated shower area for employees)
2.5 Access & Circulation
The entry and exit routes must be clearly separated into 2 distinct sides:
- Front: Designated for customers, the general public, and visitors to the learning center.
- Rear: Designated for staff and must be designed wide enough to accommodate large trucks entering to collect baled waste for export off the island.
2.6 DRS Area & Environmental Management
Because the project site is located on an island, the contractor must strictly prioritize wastewater management, especially in the operational area of the Deposit Return System (DRS), with the following minimum requirements:
- DRS and Packaging Washing Area: The area for installing the packaging washing machine and storing cleaned packaging must feature a Trench Drain with steel grating covers to trap large pieces of solid waste, and the wastewater must flow into a Grease Trap & Sedimentation Tank to filter out grease and debris before discharging into the treatment system.
- Restrooms and Shower Area (Total of 3 rooms): Must be equipped with an underground prefabricated Septic Tank, calculating the capacity to adequately handle usage, ensuring waste is treated to standard levels before seeping into the soil to prevent any negative impact on the environment and ecosystem of Koh Tao.
2.7 Electrical & Lighting Systems
The contractor must design and install an electrical system that meets safety standards for operations as follows:
- Control System and Wiring: Must install a standardized Main Distribution Board (MDB) and the entire system’s electrical wiring must be routed through conduits to ensure safety and protect against moisture and operational hazards.
- Lighting System: Must design and install appropriate lighting fixtures for each specific area, ensuring illumination is sufficient for safe operations (especially in the sorting zone and machinery operation zone).
- Plug Outlets: Must be adequately installed and distributed around the building to provide sufficient power points for the convenient connection of electrical devices in various areas.
3. Proposal Submission
Bidders must submit the following documents for consideration:
- Lay-out Plan: Demonstrating the arrangement of various zones according to the requirements, along with the traffic routing (for forklifts and trucks).
- Bill of Quantities (BOQ): Itemizing the details of material costs and labor costs, which must include the logistics and transportation costs to Koh Tao.
- Timeline (Work Plan): Specifying the timeframe from the start of design, construction, through to the handover of the work.
- Need to be submitted Within 28 March 2026
- Please submit all required documents via email to kewalint@wwf.or.th and procurement@wwf.or.th with the subject line “Quotation: Construction of the Koh Tao Community Waste Management Center (Waste Bank)”
