Winners announced for £2bn OSHA MMC Framework & PMO

Congratulations to the successful Suppliers & PMO team


The Off-Site Homes Alliance (OSHA), an alliance currently consisting of 23 Housing Associations and Local Authorities, has revealed the volumetric and panelised home manufacturers that have won a place on its new £2billion MMC framework.

The national construction framework for volumetric (CAT 1) and panelised (CAT 2) Modern Methods of Construction (MMC), will look to support Housing Associations and Local Authorities to deliver off-site homes, with the objective of developing 10,000 homes per year through the increased use of  MMC technology. The framework will also be supported by a specialist team of commissioned MMC experts across many disciplines, via an OSHA Project Management Office. The Project Management Office will be managed by specialist construction consultancy Cast Consultancy, who were successful in their bid to provide the PMO operational services to support members with project delivery. 

The framework will be administrated by Great Places Housing Group on behalf of OSHA with the successful firms supplying homes initially to its 23 members and to future new Registered Providers and Local Authority partners of the alliance. The existing OSHA Project Director (Mike Ormesher) will continue in the role currently in place, but also now acting as facilitator between the OSHA Framework, new PMO and supply chain and client partners, involved in the collaboration.

A total of 13 supply partners were successfully selected, based on their technical competence, price and commitment to social value. The successful bidders were:

  • Cast Consultancy

Social value pledges, including apprenticeships, work experience opportunities and volunteering hours were proposed by all suppliers and through a collaborative approach OSHA will be seeking these pledges to be applied on every new development.

Commenting on the announcement, Matthew Harrison Chief Executive of OSHA member Great Places Housing Group, said: “We’d like to congratulate the suppliers who have been awarded a place on the OSHA MMC framework, and Cast Consultancy for their appointment to manage the project management office. The framework was scoped following extensive feedback from our Alliance partners, and we look forward to working with the successful suppliers, Cast Consultants and manufacturing partners to realise our development ambitions of delivering much-needed affordable homes.” 

“We were pleased with the response from the market and to receive high-quality proposals and substantial social value pledges for our communities. The new MMC framework and PMO will ensure we, and our peer organisations, have tried and tested partners to help us to deliver our extensive development programmes and our collective ambitions to tackle the housing crisis.”

The MMC framework will run from February 2023 – February 2027.
