Aecom will perform the design check of the cable-stayed bridge including the complex cable arrangement and major marine foundation works. URS Scott Wilson will undertake the check of all aspects of the works, excluding the cable-stayed bridge, but including the abutments and approach viaducts to the main crossing and all roadworks and land-based structures. The independent design check of all aspects of the project has been stipulated by Transport Scotland.
The Forth Replacement Crossing is being procured by Transport Scotland through a design and build contract awarded to the Forth Crossing Bridge Constructors (FCBC) consortium of Dragados, Hochtief, American Bridge and Morrison Construction.
The main crossing across the Forth consists of a cable-stayed bridge, with the three ‘mono’ towers and two main spans of 650m each, and approach viaducts connecting the bridge to the two abutments. It will stand to the west of the existing Forth Road Bridge, which is itself west of the Forth Bridge.
Aecom director, transportation, Richard Cooke said: “The Aecom and URS Scott Wilson joint venture brings a proven collaborative track record to the Forth Replacement Crossing project team. Our combined technical expertise, in addition to Aecom’s early project involvement at feasibility stage and URS Scott Wilson’s extensive regional experience provides a synergy that will deliver significant client benefits.”
Alan Frew, URS Scott Wilson director, major roads Scotland and Ireland, added: “Having been involved in the tendering processes for this iconic scheme over many years, we are delighted to continue our close relationship with Aecom in the crucial design checking role. This is a world-class scheme that requires world-class contributions from all involved. We are convinced that our joint venture brings together the complete range of competencies and skills required to deliver on our commitments to the scheme and continues the strong relationship between Aecom and URS Scott Wilson."
