Sirsi Circle Flyover, Bangalore
The 2.5km elevated flyover is the longest and first urban viaduct of its type in India. The Consultancy was responsible for the design and construction technology of both the permanent and temporary works, which included the deck segment erection gantry and the planning of the 2.4ha precasting yard. The deck units carry a dual carriageway each 7 m wide separated by a central median, and are precast using the long-line match-casting technique and erected span by span with an overhead steel erection gantry 100m in length. the work for the contractor proved to be challenging and exiting departure from more conventional forms, which have hitherto prevailed on the sub-continent. Construction progressed at the rate of approximately one span every five days and the viaduct completed safely within a short period of time.

The Second Narmada bridge linking Mumbai and Ahmedabad consists of 13 main spans of 96.2m with 4.63km of approach roads and was built in a record period of 32 months. The box girders were built using the precast segmental method of construction and launched using a purpose designed steel truss. The two lane deck consists of a 7.5m wide carriageway with 1.5m wide footpaths on either side and is located 29m downstream adjacent to the existing bridge.
