The following Trade Specifications must be read in conjunction with all other Contract documentation including; Tender Letter, General Terms, Conditions of Contract for Works, Labour Only and Purchase Orders, General Construction Notes (England & Wales), Suppliers and Sub Contract Works - Customer Charter and the Company's Occupational Safety, Health & Environmental Management System.
Our aim is to enable our sub-contractors and suppliers to access key Commercial information such as Terms & Conditions, Trade Specification, etc. online as soon as they are updated and revised. We hope that this will ensure that our supply chain is always fully informed as quickly as possible.
Whilst available online, this information is also available from the Commercial Departments at our Divisional offices and will form part of any contract we place (as set out in the Order).
Please be aware that bogus web sites seeking fees for the chance of working with major contractors exist.
