The Royal National Orthopaedic Hospital will detail its plans at a bidders’ open day next Thursday at the Stanmore site.

The Enquirer understands the scheme has caught the eye of Balfour Beatty, Skanska, Bouygues and Laing O’Rourke. Also rolling up will be Sir Robert McAlpine, Interserve, Kier, Vinci and Bovis Lend Lease.

The hospital trust wants to build a new 124 in-patient ward along with imaging department, landscaping as well as café and retail facilities.

Interested bidders have until February 21 to request information on the 15,000 sq m scheme with the trust due to name a preferred bidder at the beginning of 2013 with work on site starting later that year.

Information can be requested by calling Steve Turner, PFI Project Director on tel: 020 8909 5105.

Meanwhile, a much larger PFI hospital scheme is also set to be advertised later this spring which has attracted the interest of Spanish firms FCC and Dragados.

The £370 million hospital in Smethwick will be called the Midland Metropolitan Hospital after a public vote to give it a new name was held last year.

An outline business case for the scheme is being looked at now by officials at the Treasury and the health department but health secretary Andrew Lansley has OK’d Sandwell and West Birmingham NHS Trust’s plans to buy up land to build the new hospital.

Trust bosses want to open the new hospital, which will have 666 beds and run across 80,000 sq m, by 2016.

In 2008, FCC became the first Spanish firm to land a PFI hospital contract in the UK when it pipped Skanska and Balfour Beatty to the £267 million deal at Enniskillen in Northern Ireland.
