the project is in the heart of delhi, as a private sector execution on a build-own-operate & transfer (boot) basis at a cost of rs. 40600 lakhs (main project). the toll plaza project alone costs about rs. 1400 lakhs. it features a 'state of the art' 27 toll lanes set-up with 19 toll booths covered by a 6 metre (average) high canopy of 300 m x 16 m. it has a tunnel serving the toll collectors and its entire equipment, which links the buildings of the plaza to the individual booths and further to the canopy. the plaza's life lines, i.e. data cables, electrical and telephone lines, ventilation ducts and plumbing network are all housed in this 200 m. tunnel running orthogonal to the traffic above.
the buildings were segregated functionally into four blocks; the administration office building and toll management block, which receives the tunnel and monitors the entire plaza activity took centre-stage. the maintenance block is strategically placed to monitor the plaza and opens to a maintenance yard. the third block of point - of - sales is operationally placed on the service lane in proximity to the main building. the substation and the police booth (not built) were positioned at the end of the service road, away from the main masses. the area is guarded by retaining walls towards the bund road. also, the plaza was proposed (not built) as a connected sequence of building bound by a central wall, encompassing the plaza and focusing it to the booths which are the nodes where the toll is collected. the entire built up area is about 25,000 sq. feet. archohm's scope of work included the total conceptual design, architectural and interior works, detailed engineering i.e. structural, electrical, plumbing, air-conditioning and ventilation systems' design. it also included complete design calculations, proof checks, preparation of tender documents ic. formulation of technical specification and bills of quantities for all disciplines, advice and assistance to the client in placement of orders for the contractors as well as materials, consultant supervision at the site and witness of the commissioning tests.
