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. Eighteen 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 main objective of this Manual is to capacitate Local Bodies such as Palikas/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.
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.
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. The Manual also prescribes standard service charges for respective engineering services.

The course includes preparation of construction materials such as stone dressing; preparation of aggregates etc. and construction works such as concreting and masonry works and bridge erection.
The training is conducted through practical works by building a demonstration model bridge, hence the popular name “Demonstration Model Bridge Training (DMBT)”. The training is based on demonstration and learning by doing technique.
This Routine Maintenance Manual has been prepared with the view of imparting knowledge and know-how to Bridge Wardens, Bridge Inspectors, Bridge Maintenance Committees, Technicians of Palikas and local communities on how to maintain trail bridges so as to increase their longevity.
Picture illustrations have been used extensively along with brief summaries to make it reader friendly.
This Manual on Comprehensive Monitoring comprises of all safety and quality control aspects for both new as well as existing bridges; the detailed roles of Palikas, LBS/DoLI; and the use of Private Sector for Monitoring and Inspection.
The Manual covers Planning of bridges collectively and the Implementation of individual bridges. The Manual is based on the premise that the Palika/Province will monitor / inspects a random sample of bridges. The Manual has been disseminated through the IoE to prospective private sector Monitors / Inspectors. This Manual has been drafted in consultation with the National Vigilance Center.
