This presentation summarizes the construction of a highway bridge over the Sali River in Bankura District, West Bengal. The 172.24 meter long and 12 meter wide bridge has a carriageway of 7.5 meters and is supported by pile foundations and RCC girders. It consists of 2 abutments and 6 piers founded on 112 piles. Safety aspects of the project are highlighted. The presenters acknowledge the guidance provided by the site engineer and team from MACKINTOSH BURN LTD., who are supervising the construction of the bridge.

8. PILE FOUNDATION
Pile foundation is required when the soil bearing
capacity is not sufficient for the structure to
withstand. Pile foundations are capable of taking
higher loads than spread footings.

9. BEARING
A bridge bearing is a component of a bridge which typically
provides a resting surface between bridge piers and the bridge
deck. The purpose of a bearing is to allow controlled movement and
thereby reduce the stresses involved.
The Elastomeric bearing allows the deck to translate and rotate, but
also resists loads in the longitudinal, transverse and vertical
directions.Elastomeric Bearing at the site

12. PRELIMINARY SURVEY
BENCHMARK: G.T.S BENCH MARK TAKEN FROM SONAMUKHI -- DURGAPUR ROAD OF
D.V.C CANAL BRIDGE ON TOP OF EAST SIDE WING WALL OF VALUE - 196 FT. OR 50.780 M
 With the respect of D.V.C canal benchmark a new benchmark is set up near the site
of 50.24 m RL
 The instruments used to determine reduced level include Optical Levelling
instruments like Automatic Level, Levelling Staff and Tripod stand RL of a survey
point is determined by Height of Instrument method.

13. SAFTEY ASPECTS
 A firm, well supported walking platform should be used while
working at heights to ensure safety
 TMT rods should been stacked properly
 Availability of Hand gloves, safety helmets, safety belts and safety
shoes
 Caution boards should be provided
 Fire extinguishers should be provided on site

14. ACKNOWLEDGEMENT
We can conclude that there is difference between the theoretical and practical work done. As
the scope of understanding will be much more when practical work is done. As we get more
knowledge in such a situation where we have great experience doing the practical work.
I express our ineptness and gratitude to our site engineer of MACKINTOSH BURN LTD. for his
guidance, support and care taken by him in helping us to complete the project work
successfully. I am thankful to his team members for their support and guidance throughout the
period of project.
