Micro-piles were chosen because basement with its limited by height could be accessed ...

Our bridge comprises of 5 Nos. steel plate girders, each of 61.4m length and 60.8m c/c of bearings + 225mm thk concrete deck slab. Overall Bridge width is 11.15m. Each girder weighs 140 tons including all the steel work. Deck cross section comprises of 5 plate girders at 2125mm c/c with two cantilevered ...

For existing buildings where limited or no information is available we have used 'reverse' engineering approach i.e. to take inventory of existing structure, assess its condition and estimate residual load carrying capacity. Then modify/strengthen the structure as dictated by additional load requirements. ...
