SNV Netherlands Development Organisation
Terms of Reference
Design of Medium Size Biogas Digester and Writing of Construction Manual
1. Background
SNV is a non-profit international development organization, established in 1965 in the Netherlands. SNV works in the sustainable agriculture, renewable energy, and water, sanitation and hygiene sectors. Services within the renewable energy sector include domestic biogas, biofuels and improved cookstoves with a focus on providing clean energy for cooking. SNV's work in biogas in Indonesia, since 2009 under the partnership with Hivos, has focused on supporting the establishment of domestic biogas plants that convert manure produced at the household level into combustible methane gas that can be used for cooking and lighting lamps. The overall goal is to develop a sustainable biogas sector where local companies market and install biogas plants as well as provide after sales services. This systems approach also involves strengthening organizational and institutional capacities in local level and optimizing cooperation between the private sector, government, and end users.
SNV is currently looking to establish a presence in Indonesia in its own right and is undertaking preparatory work. With the financial support of EEP Indonesia and SNV, we will be conducting a pilot project with local partners to examine the potential of Medium Scale Biogas Project in Central Kalimantan. 10 medium size digesters will be constructed at community cattle sheds with the gas produced distributed to nearby households for cooking and lighting.
The overall objective of the project is to develop and test a reliable biogas design appropriate for the Indonesian context and design the necessary operation and management system for a community digester.
The project promotes development of a robust and cost effective medium scale biogas sector that improves access to clean and sustainable energy sources by households in Indonesia. About 10 units will be set up as pilots in Central Kalimantan.
One of the key activities of the projects is to design and develop an appropriate medium size digester suitable for the Indonesian context. For this purpose, SNV wants to engage a suitable consultant for the development of the biogas design and prepare a construction manual including Bill of Quantities for the digester.
2. Objectives
The main objective of the assignment is to design and develop a suitable fixed dome design for a 50m3 digester for cattle dung.
3. Scope of Work
The scope of the assignment is as follows:

2. Objectives
The main objective of the assignment is to design and develop a suitable fixed dome design for a 50m3 digester for cattle dung.
3. Scope of Work
The scope of the assignment is as follows:
- Design of fixed dome digester of 50m3 size which is strong enough in earth quake prone areas,
- Develop detailed construction manual for the purpose of mason training
- Prepare bill of quantities and estimated price of the digester
4. Approaches and Methodology
The Consultant should outline the detailed approach and methodology for carrying out this assignment. The methodology shall include a desk study and review of relevant literature related to the project. There are many types of digesters being used in the region and those designs should be critically reviewed. If necessary, consultation and inputs should be received from the experiences of biogas experts from other countries. Based upon the review of designs and consultations, the consultant shall formulate the design specifications which shall be finalized in agreement with SNV. While designing the digester, the following parameters should be taken into consideration:

Based upon the review of designs and consultations, the consultant shall formulate the design specifications which shall be finalized in agreement with SNV. While designing the digester, the following parameters should be taken into consideration:
- Cattle dung based
- Suitable for earth prone areas,
- Low cost as far as possible
- User friendliness
- 100% gas tightness
- Longer life and less maintenance required
- Efficient for maximum gas production
5. Expected Output
- Clear design with working drawing
- Detail construction manual with step by step process and illustrations both in English and Bahasa Indonesia
- Detailed and realistic bill of quantities
The drawings should be preferably developed using an AutoCAD. Three
copies of final design specifications and drawings with detail
measurement calculations, three copies of construction manual each in
English and Bahasa Indonesia, one copy of bill of quantities and an
electronic copy (in CD) of all documents must be submitted to SNV. The
reports must be prepared and performed in a professional way by adhering
to strict quality standards.
6. Work Schedule
The project will be implemented tentatively from the third week of March 2013 and expected to completed before 15th April 2013. The consultant shall provide a detailed work schedule for implementation of the assignment. This will be finalised in conjunction with SNV.
7. Team Composition
The team should be composed of :
