Common minimum standards

'Government Construction: Common Minimum Standards for procurement of the built environments in the public sector' is generally referred to as the Common Minimum Standards (CMS), although the Government Construction Strategy proposes that it should be renamed the Government Construction Standards.

The CMS can be downloaded in full from the Gov.uk website.

The CMS summarises existing government policy on construction. It states that central government construction projects (including departments, executive agencies and the non-departmental public bodies for which they are responsible) should be carried out '…with full reference to the CMS'. Where public projects have been devolved to the wider public sector, reasonable measures should be taken to ensure that the CMS are adopted.

The CMS is quite short at just 17 pages. It includes guidance on:

Before the CMS was published, the Office of Government Commerce (OGC) produced a great deal of guidance about best practice in procurement and project management. OGC has now been absorbed into the Cabinet Office, and OGC guidance has been archived, however, much of the guidance in the CMS mirrors the procedures set out in the OGC Gateway Review Process, and OGC guidance is referenced in the CMS.

Similarities between the OGC Gateway Review process and the CMS include:

Requiring that projects undertake OGC Gateway Review risk profile assessments and the OGC Gateway Review process (or similar approved process).
Requiring collaboration and the early appointment of an integrated supply team.
Proposing that contract routes other than PPP (public private partnership) / PFI (private finance initiative), design & build, prime contracting and framework arrangements …should not be used unless it can be clearly shown that they offer best value for money.
Proposing the use of the PAS 91 (Publicly Available Specification) standard pre-qualification questionnaire.
Proposing the development of an output-based specification.

The CMS also includes references to:

The principles set out in the Government Construction Strategy.
Fair payment practices.
The Green Book (the government framework for the appraisal and evaluation of policies, programmes and projects).
A requirement to collect and analyse health & safety data.
A requirement for contractors to be registered with a good neighbour scheme.
A requirement to assess buildability, functionality, maintainability, sustainability and future flexibility when assessing designs.
A requirement to comply with the Protocol for the Care of the Government Historic Estate.
A requirement to follow the procedures set out in Achieving Excellence in Construction Procurement Guide 11: Sustainability.
A requirement to take account of the Government Buying Standard for construction. This requires the adoption of an environmental assessment process. Where BREEAM (Building Research Establishment Environmental Assessment Method) is used, new projects should achieve an ‘excellent’ rating, and refurbishment projects with a value over £500k should achieve at least a ‘very good’ rating.
A requirement to procure timber in accordance with the governement’s timber procurement policy.
A requirement to fall within the upper quartile of energy performance for that building type.
A requirement to take account of resilience to climate change.
