CCS has awarded a new agreement for offsite construction, which aims to support the public sector to innovate, drive efficiency and continue to work towards their CNZ targets

The Offsite Construction Solutions (RM6184) agreement reflects continuous Modern Methods of Construction (MMC) innovations and will broaden the premanufactured building solution provision currently available to public sector buyers through CCS agreements. It will have an increased scope to include more MMC categories, specifically 2D panelised structural systems and panelised external building retrofits, as specified within the new MMC Definition Framework.

The agreement will continue to align with the policies outlined in the Construction Playbook on offsite construction adoption. It replaces our Modular Buildings Agreement, which closes on 1 April 2023. It has been designed to assist all public sector customers, with a specific focus on the health, housing, education, justice and defence sectors.

In a bid to help the public sector to continue to meet their carbon net zero targets, a specific lot (Thermal Efficiency Upgrades) has been introduced to address the increasing demand to retrofit existing estate portfolios with thermally efficient external systems.

The new agreement aims to build on the progress made on making it easier for small and medium-sized enterprises to become suppliers. It includes 29 suppliers, 18 (62%) of which are SMEs. 

The agreement will run for 4 years with the possibility of a 3-year extension and there is no maximum duration for call off contracts

John Welch, Deputy Director – Construction, Crown Commercial Service says:

This new framework will support the public sector in the design, delivery and commissioning of a whole range of offsite construction projects in the coming years, including social housing, new schools and hospital extensions. These projects, and the many more which will come, have the potential to improve services and the lives of millions of people.  

It is yet another example of how CCS is helping the public sector to support the government’s construction strategy and further supports the recently published refresh of the Construction Playbook with its MMC guidance note.
