Manuals

Manuals play a key role in disseminating the trail bridge technology (survey, design and cost estimate) and its implementation modalities. It also help to standardized the processes and approaches of trail bridge program. NINTEEN of such manuals and guidelines are already developed and is in the use by the trail bridge building agencies. These manuals have facilitated the process of devolution of trail bridge program to the local bodies. As the trail bridge program is slowly evolving as a sub-sector, a couple of more new manuals/guidelines are already in the developing stages. It is expected that these efforts will help streamline the trail bridge sub-sector programs in the country as a whole.

The maximum span is 32 meter. The standard designs are included for 16, 20, 24, 28 and 32 meters span.


5. Social Organizational Support Manual

The main objective of this Manual is to capacitate Local Bodies such as DDCs/NGOs in social and organizational aspects of the Community Trail Bridge Program so as to be able to extend the right level of support to bridge User Committees to build Short Span Trail Bridges. 

This Manual, defines nine steps, starting from the identification of the need of the bridge through to the Final Inspection and formation of the Bridge Maintenance Committees.

 

6. Quality Control Manual

The Quality Control Manual consist all technical specifications of services, goods and works of trail bridges, quality control as well as quality assurance procedures for both SSTB and LSTB bridges.

This also includes quality assurance documents, inspection procedures and inspection formats/checklists.

7. Manual for Consulting Services

This manual provides guidelines for the bidding process and contract management of procurement of engineering services for LSTB bridges. It includes standard bidding documents for engineering services for LSTB bridges, i.e., Bid documents for 1. Socio-economic studies, 2. Detail engineering survey and design, 3. Construction supervision and quality control, and 4. Third party technical audit. The Manual includes ToR and job descriptions for each engineering service.
