Introduction to the Framework

SWPAs Offsite Project Integrator framework can be used by local authorities, housing associations and other social landlords to find the vital technical support they need to deal with the unique challenges, associated with the integration of offsite projects including volumetric, panelised, high-rise and turnkey building systems and to make your offsite project a success.

This framework can be used interpedently for MMC projects, or alongside our two MMC construction frameworks – Offsite Construction of New Homes (NH2) for residential projects and Modular Buildings (MB2) for non-residential developments.
