Offsite Construction Solutions (RM6184) replaces the Crown Commercial Service’s (CCS) Modular Solutions Framework, which closes on 1 April 2023.
The new framework, which opened on 24th January, is designed to cover a broader range of manufactured and prefabricated building systems and components, specifically 2D panelised structural systems and panelised external building retrofits.
It has been designed for use by all public sector clients to promote the standardisation of building design across government property but it has a specific focus on the health, housing, education, justice and defence sectors.
The agreement runs for four years with the possibility of a three-year extension.
Of the 29 firms on the list across six lots , 18 (62%) are described as SMEs – small or medium-sized enterprises.
There six lots are:
- Built estate including education
- Healthcare
- Residential
- Justice
- Defence
- Thermal efficiency upgrades.
Lot 6, thermal efficiency upgrades, has been introduced to address the increasing demand to retrofit property with thermal improvements.
John Welch, deputy director for construction at the Crown Commercial Service, said: “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.â€
