Design team appointed for preliminary planning and design for St Mary’s Hospital redevelopment

With the support of the New Hospital Programme, Imperial College Healthcare is beginning the next phase of redevelopment planning work for St Mary’s Hospital which, along with the Trust’s Charing Cross and Hammersmith sites, is included in the 40 new hospitals the government has committed to build by 2030.

This involves awarding contracts to companies to undertake the first stages of design brief and planning work, including feasibility studies for various options and phasing and a high-level masterplan for the whole site (RIBA 0-1 stages). The work is due to be completed by May 2022 when the Trust also expects to have more clarity on next steps following feedback on the strategic outline case it submitted to NHS England/New Hospital Programme in September 2021.

The following companies have been appointed to deliver RIBA 0-1 stages design brief and planning:

  • HOK - lead architect
  • Ramboll – civil and structural engineering
  • AECOM – mechanical and electrical engineering (MEP), BREEAM (sustainability assessment) and cost management consultants
  • ETL - healthcare planning
  • Gardiner & Theobald - project management

In addition, AHMM has been appointed master planning architect, subcontracted to HOK.

The design team comprises the ‘preferred bidders’ for the subsequent stages of the St Mary’s redevelopment (RIBA 2-7), determined through a tender process in 2020. The appointments for RIBA 2-7 are still subject to agreeing contracts and further funding.

Related planning is also underway to broaden involvement – and facilitate co-design – with staff, patients, local communities and other stakeholders for all three of Imperial College Healthcare’s sites included in the New Hospital Programme.
