The project consists of design of roads for 25km in a hilly terrain. The scope of Spectrum includes topographic survey , geotechnical investigations, geometric design, pavement design for left bank & right bank approach roads in hilly terrain to middle Vaitarna dam including major & minor bridges and CD works, preparation of tender documents and assisting M.C.G.M. in tender evaluation.
The Project consists of PSC "I" girder type Super Structure with Open & pile Foundation. Total Length of the flyover is 715 m. The Super Structure consists of three (or four) spans continuous units. Each span comprises of 6 Paralel girders. Each girder has 3 Pre-cast RCC segments stitched together by pre stressing.
Project involves design of the flyover of 1040 m total length with pre cast segmental construction for superstructure. The superstructure consists of 19.7 m overall width for 2 carriageways of 8.75m width each and have fish belly shaped box girders, constructed using overhead launching girder. Typical unit consists of three or four continuous units of 40m each.
Project involves planning & design of Skywalks in city of Navi Mumbai, at various railway stations. The responsibility includes traffic survey, analysis, short listing the sites, topographic & geotechnical surveys, finalizing the layouts & widths, general arrangement and detail engineering of the skywalk. The first skywalk being taken up at Kharghar has a Cable stayed structure spanning across the Sion-Panvel Highway. The Services also includes preparation of tender, specifications, and periodic visits to sites.
The bridge consists of two swinging arm of length 27m each, with 18.5 long steel cantilever ends towards center. The back portion towards abutment is in RCC and resting on 3.0 m dia rotating bearing. The bridge is designed for IRC Class A loads. The steel portion consists of two longitudinal built up girders of depth 1.4m at center and 1.9 m at fixed end. The transverse girders with depth 900mm are placed at 2.7 m c/c. The deck is with steel trough and asphalt fill.
The project involves three flyovers on Thane-Ghodbunder road having 4 lanes carriage way, 17.2 m width and continuous span of 4 x 30m and 5 x 30m. The flyover consist of precast segmental fish belly shaped box girder superstructure on architecturally shaped RCC piers over pile foundations while open foundations are adopted for abutments.
