There are a number of agreements and contracts for the appointment of consultants from the leading providers ACE, JCT, NEC, and RIBA.
Appointments refer primarily to the situation where the client contracts designers (such as architects, landscape architects, engineers, specialist designers, specialist contractors, etc.), or other consultants (such as cost consultants, independent client advisers, site inspectors, project managers, client representatives, etc.).
On publicly-funded projects, the consultant team will often be contracted along with the main contractor as part of a complete 'integrated supply team', and so appointments may be restricted to independent client advisers and project managers.
