Balfour, Cintra, Plenary vie for Colorado road PPP

The second phase of a $310m effort to upgrade and widen US Route 36 in Colorado has lured Balfour Beatty, Cintra and Plenary Group. A RFP can be expected by August.

The latest chapter of a $310 million project to renovate US Route 36 in Colorado has garnered strong private sector interest from consortia comprising Balfour Beatty Capital, Cintra and Plenary Group.

‘Phase 2’ of the undertaking – named the US 36 Managed Lane/Bus Rapid Transportation Project – is a projected public-private partnership (PPP). The Colorado Department of Transportation (CDOT) conceived the project to relieve traffic congestion brought on by “rapid population growth”.

CDOT and its High Performance Transportation Enterprise (HPTE) office issued a request for qualification (RFQ) for Phase 2 in February, attracting interest from:

– Accelerate 36 Consortium, teaming Atkinson Construction, Balfour Beatty Capital, Portugal-based Brisa, Edgemoor Infrastructure and Real Estate, Parsons Brinckerhoff and Scotiabank;

– Denver Access Partners, a consortium of AZTEC Engineering Group, Cintra, Ferrovial Agroman and Lawrence Construction;

– Plenary Roads Denver, partnering Ames Construction, Goldman Sachs Group, Granite Construction, HDR, Plenary Group and Transfield Services;

– US 36 Development Partners, a consortium of Atkins, Bank of Tokyo-Mitsubishi UFJ, Isolux Corsan, Terracare Associates and THB Advisory.

CDOT said a bidder shortlist should be announced in May, with a request for proposals (RFP) slated for mid-August.

The second phase of the US Route 36 project followed a prior design-build mandate, awarded last month to an Ames/Granite joint venture. The crux of the project is a widening of US Route 36 between Boulder, Colorado, and Denver, where the interstate highway is a four-lane, outmoded thoroughfare.
