Introduction to the Framework

This framework has been developed to provide an efficient, value for money procurement route for local authorities, social landlords and other public sector bodies for the offsite development of new residential buildings using modern methods of construction (MMC).

This framework agreement can be used for:

  • General housing
  • Apartments (including student accommodation and care homes)
  • Adaptive pods
  • Room on the roof projects
  • Temporary accommodation
  • Enhanced energy performance and net zero carbon projects
  • Groundworks for offsite projects

Our vision for the framework

This framework is designed to support WPA Clients to increase the use of Modern Methods of Construction (MMC) in delivering their housing programmes.

  • Meeting the ‘Gold Standard’
  • Promoting early collaboration between Clients and Appointed Companies
  • Bringing Clients together for aggregation of demand
  • Delivery of Net Zero Public Sector Buildings standard to support public bodies in meeting their net zero commitments for their new build projects.
  • Increased use of Pre-Construction Service Agreements (PCSAs)

Want to adopt modern
methods of construction?

The MMC definition framework provides a new
regularised terminology for ‘Modern Methods
of Construction’ used in home-building.

Well-being of Future Generations

The Well-being of Future Generations Act gives us the ambition, permission and legal obligation to improve our social, cultural, environmental and economic well-being.

The Well-being of Future Generations Act requires public bodies in Wales to think about the long-term impact of their decisions, to work better with people, communities and each other, and to prevent persistent problems such as poverty, health inequalities and climate change. Welsh Procurement Alliance is mindful to ensure that the Future Generations Act obligations are embedded into all our activity.

With the Well-being Goals in mind, WPA is committed to providing our clients with competitively tendered Framework Agreements for building works, goods and services and to delivering tangible social value and community benefits that meet local and regional needs. WPA work with our clients and appointed companies to ensure that wherever possible projects delivered using our frameworks leave a social legacy.
