Our Services


By adopting and adapting & using the State of the Art New Technology with Innovative Engineering Concepts / Techniques in Constructing Bridges, we have adopted technology to suit the individual requirement of each Bridge site. We have developed a Special Expertise in Bridge Design, Construction and Rehabilitation – by deploying qualified and motivated personnel, supported by latest High - End Computers, State of the Art Computerized Machinery and Testing Equipments etc. Our Engineers have Extensive Expertise and Experience coupled with inhouse availability of equipments and instruments available which has enabled the Construction of Chenab Bridge at Akhnoor in Jammu & Kashmir, which was lying incomplete for the last 30 Years till the work was entrusted to us on 28th April. 2006. This Bridge has been Designed and Constructed as 280 mtr long ( 60 m x 2 + 160 m central span ) cantilever PSC Box section continuous bridge supported on 2 Nos of Piers and 2 Nos of Abutments on Well Foundations. The construction of this Longest Prestressed Concrete Span of 160 M, using the heaviest bearings (23 nos weighing 47. 10 MT and maximum capacity 4000 MT ) ever used in any Bridge , concreting 2 (4 m each) pairs of segments sequentially within 24 hours; shortest time cycle of 06 days (for each segment) which was consistently achieved for the construction of each segment has created a landmark in the construction of Bridges.
