The Rewa Bridge project was a design-build contract undertaken for the Government of Fiji Public Works Department. It involved the construction of a 425m long, four-lane bridge in Nausori, Fiji. Abutment and pier foundations consisted of 204, 610mm diameter steel tube piles driven to depths of 50m.
The bridge site is situated on the western fringes of a large deeply eroded river valley, with the depth to rock ranging from 13m at the western abutment to 80m at the eastern abutment. We developed an alternative foundation design in conjunction with Fletcher Construction which involved the use of driven steel tube piles in place of bored cast in-situ concrete piles.
The geotechnical design challenges included use of both end bearing and friction piles, liquefiable sands beneath the abutments and full scale pile load testing.
Valued at $FJD34 million, this project was completed in 2006 and in 2007 was the recipient of an ACENZ Gold Merit award.
