At a recent reception at the House of Commons the JCT launched two new suites of products: The 2011 Edition of the Joint Contracts Tribunal (JCT) standard form suite of contracts and A new Public Sector Supplement tailored specifically for public sector clients and their contract administrators that can be used in conjunction with JCT contracts in the procurement of public sector projects. JCT contracts are used extensively throughout the industry – on four out of five of all building projects in the UK. The 2011 Edition updates the 2005 edition and includes the changes needed to accommodate the revisions to the Construction Act that come into effect on 1st October. The Public Sector Supplement is the first of its kind, is free of charge and contains: - Provisions to ensure alignment with the Government’s Fair Payment Guidelines. - A model clause authorising disclosures by public sector clients in accordance with the Freedom of Information Act 2000 and the Government’s Transparency Policy.
