Tilbury Douglas is proud to be a framework contractor on one of the UK’s largest public sector frameworks.
Benefits of using this framework
The CCS Construction Works and Associated Services (CWAS) agreement is a pan government framework which can be used by all public sector bodies to build offices, schools, hospitals, universities, prisons and housing.
The flexible contract structure is designed to provide solutions for varying customer requirements. It includes advanced, innovative contract arrangements, allowing customers to procure programmes of work as self-managed sub-alliances.
The framework is arranged in 11 lots of varying levels of complexity and value, including general construction and specialist market areas e.g., high rise, maritime, airfields and demolition.
All commonly used procurement routes, tendering methods, payment arrangements and standard forms of contract are available.
Key focus of this framework: Supporting government policies & strategies
The framework supports the implementation of government policies and strategies including BIM, lifecycle cost, prompt payment, project bank accounts, early contractor involvement (ECI) and Social Value.
It also aligns suppliers and customers in achieving agreed success measures for each lot. Advanced alliance facilities are included to increase the potential for consistency, efficiency, improved value and lessons learned through integration and collaboration.
