The Enquirer understands that the award was confirmed on Monday to firms left in the race and Carillion has now made a Stock Exchange announcement.
Five firms were on the original shortlist which was whittled down to three at the start of this month.
Carillion was left to battle it out with Laing O’Rourke and Brookfield after Lend Lease and Sir Robert McAlpine fell by the wayside.
Carillion has now bagged the deal marking a stunning return for the contractor on major central London building projects.
Turner & Townsend is project manager on the £350m first phase known as Circus West.
Work will involve construction of a mix of 866 apartments with a blend of offices, shops, community and cultural spaces designed by Ian Simpson Architects and de Rijke Marsh Morgan.
The main block will vary in height from 8 storeys at its southern end, rising to 18 storeys and then reducing to 12 storeys at its northern end.
The second block will be 8 storeys high. Extensive hard and soft landscaping is included as part of the Phase 1 works.
Carillion will start on the site this summer with work scheduled for completion in 2016.
Carillion Chief Executive, Richard Howson, said: “We are delighted to have been selected as the preferred bidder for this prestigious project, which I believe reflects Carillion’s reputation for delivering high-quality, value for money projects.
“We look forward to working in partnership with the Battersea Power Station Development Company to deliver this iconic project that will make a major contribution to the transformation of this historic site.
“This takes the total value of new orders and probable orders for Carillion in 2013 to some £2.6 billion and demonstrates the benefits of our strategy in construction services of focusing on national projects.”
Chief Executive of Battersea Power Station Development Company, Rob Tincknell, said: “This will be one of the largest construction contracts to be awarded in recent history and, on behalf of the Battersea Power Station shareholders, we are delighted it will go to an award-winning British firm.
“The first phase of any redevelopment is an important statement of the qualities that will govern the entire project and for that reason we took a lot of time selecting the contractor.
“After a great deal of consideration, we believe Carillion is best placed to deliver the ambition, precision and rigour that people rightly expect from a scheme which will flank a building as famous and distinguished as Battersea Power Station.
“Battersea Power Station is the last central London regeneration project of its sort and over the course of the redevelopment it will generate 15,000 new jobs, 3,500 new homes and the restoration of the historic Power Station.”
