The Defence Infrastructure Organisation has given a new 2013 award date for its £400m National Capital Framework, with ten firms invited to tender.
Previously, the deadline for the contract award was given as May 2014.
The DIO says it intends to award places before the end of 2013 and run for an initial four years, with a potential extension of up to three years.
A clutch of major firms were invited to tender on the shortlist:
The framework will comprise the design and build of construction projects worth up to £50m.
Up to five companies will take part in competitions for individuals projects.
The framework, which is aimed at delivering construction projects across the UK defence estate, forms part of the Next Generation Estate Contracts programme.
It is planned to operate alongside six regional capital works frameworks for projects valued below £12m.
The framework can be used on any site across the UK estate, and has an estimated value of between £250m and £400m.
Evaluation criteria include supply chain management, quality assurance, sustainable development, health and safety, and Government Construction Strategy issues.
All contractors will also be required to use systems that meet UK government BIM requirements, and to observe Fair Payment Practices.
Project bank accounts will be set up “where decided appropriate on a project by project basis.”
Tenders are due to be returned by mid-February next year.
Tenderers have also been provided with a demonstration construction project, and will be evaluated on their proposed approaches to the project’s delivery.
NGEC head Steve Rice said: “Changes to UK military basing arrangements are expected to generate requirements for new capital works in the years ahead, and it is vital these are met flexibly and cost-effectively, enabling us to provide a Defence estate which meets military needs and supports our Armed Forces.
“Early in the NGEC programme our research determined that framework arrangements were the best mechanism to achieve this, and I am delighted that we have such a strong field of companies in the competition.”
NGEC Capital Works Frameworks projects manager Jon Wooden said: “This national framework is designed to deliver a range of potential major construction projects to support the Defence frontline.
“We are determined to ensure firstly that all companies involved in the tendering process have a full and robust understanding of the potential demand, and secondly that we use the evaluation process to identify the best providers to meet that demand.”
