Isolux Corsan and Plenary Group are squaring off for a $312 million deal to ‘develop’ a public-private partnership (PPP or P3) involving US Route 36 in Colorado, according to the High-Performance Transportation Enterprise (HPTE).
The HTPE, a Colorado Department of Transportation (CDOT) office dedicated to surface transportation, said ‘Plenary Roads Denver’ and ‘US 36 Development Partners,’ a consortium including Isolux, responded to a request for proposal (RFP) published last August.
The HTPE in May 2012 shortlisted Plenary, US 36 Development Partners and ‘Denver Access Partners,’ a consortium teaming Cintra Infraestructuras, Ferrovial Agroman, Lawrence Construction Company and AZTEC Engineering Group.
Denver Access Partners did not respond to the RFP. A fourth team, ‘Accelerate 36 Consortium,’ including Balfour Beatty Capital, Edgemor Infrastructure and Real Estate, Brisa, Atkinson Construction, Parsons Brinckerhoff, and Scotiabank, were not issued the RFP.
The Plenary Group consortium comprises Ames Construction, Granite Construction, HDR, Transfield Services, and Goldman Sachs Group.
In addition to Isolux toll road unit Isolux Infrastructure, Kiewit Infrastructure Company, Atkins, Terracare Associates, and Bank of Tokyo-Mitsubishi UFJ make up US 36 Development Partners.
The winning bidder will design, build, finance, operate and maintain a 50-year toll road concession of a 24-mile span of US Route 36 in Colorado.
The HTPE is expecting to announce its ‘preferred proposer’ in April.
