PROJECTS

Dedicated freight corridor from Vaitarna to Utran (Approx. 200 KMs) is a part of Western corridor being commissioned by DFCCIL. This section is located along Vasai – Bharuch Section of Mumbai Central – Vadodra Route of Western Railway. The entire proposed DFC alignment in this section is located on east side of existing Indian Railway (Western Railway) track and runs adjacent to the existing IR Track except near Valsad, Dhanu Road and Surat where the DFC has planned on a detour to avoid the congested areas in these cities. The broad scope, is to design and construct 54 (Fifty four) important and Major bridges on the proposed new double line DFC track between Vaitarna station and Utran station of Western Railway. Forty seven bridges are all to be constructed adjacent to existing Western Railway bridges on the parallel alignment while seven bridges fall on detour. Accordingly, the design of bridges in parallel section has to take care of adjacent bridge being on the upstream side.

Delhi has developed practically like a twin city across the River Yamuna. The area towards the East of River Yamuna has high residential density while employments are mostly available across the river on the Western side. This results in very large volumes of vehicular traffic across the river. Presently there are seven bridge/barrages connecting the two sides of the river. With the Shantivan bridge at Geeta Colony the nos. of links across the river will rise to eight. However, centrality of the I.P Barrage and Nizamudin Bridge results in very heavy movement of vehicular traffic along these two corridors. The nos. of traffic lanes available across the river are already inadequate to carry even the present level of activity. The objective of this assignment is to have aesthetically pleasing, technically sound, durable and economically viable, connection corridor between East Delhi and Ring Road Near WHO office. The alignment passes through the unoccupied land behind CNG station, DJ\1RC sub-station and IP Bus Depot. An innovative construction technique such as Extradosed Bridge over River Yamuna has been contemplated. Extradosed Bridge form has the advantage of entailing a comparatively shorter pylon yet a distinct structural form. In terms of cost, this form maintains a good optimum between Cable Stayed Bridge and Precast Segmental Bridge.

Delhi Metro Phase 2:Central Secretariat to Gurgaon Corridor - Underground Stations & Tunnel

The project comprises of 4 nos. underground stations and tunnels between ch.21150.80m to 24600.00m. The stations are at Race Course, Jorbagh, INA and AIIMS. All the stations are proposed to be constructed by cut and cover method. 800mm thick Diaphragm walls are proposed to be installed for “top down” method of construction. The length of each station is 318m & width is 21m including 20m workshaft areas of both ends for launching & retrieval of Tunnel Boring machines. The stations consist of island platform with trains on both sides. The clear span for the roof slab is 20.65m

Delhi Metro Phase 2: Central Secretariat to Badarpur Corridor - Underground Stations & Tunnel

The project consists of tunnel and 3 nos. stations between km. 0.684 to km. 6.100. The three stations (Khan Market length239m & width 20m, JLN Stadium length 300m & width 20m and Jangpura length 285m & width 20m ) under construction are in extremely difficult and sensitive areas. The stations are to be constructed generally by “bottom-up” construction. The Jangpura station is located below the flowing waters of the Nallah Drain, and will be constructed by “top-down” techniques. The launching and retrieval shafts are a part of the station structure except near Udyog Bhawan where a full-fledged 60m long launching shaft is to be installed in rock which is sloping both transverse to as well as along the alignment.
