A pre-construction services agreement (PCSA) is used to appoint a design and build contractor to carry out services before entering into a formal building contract. A PCSA is sometimes referred to as a pre-construction agreement (PCA) and is used in two-stage tendering to obtain further design input, buildability advice, technical advice and detailed costs information from a prospective contractor.

A PCSA is a formal agreement to provide specified services (and sometimes to carry out specific works) and is not a letter of intent.

This PCSA is drafted on the basis that the parties intend to use an amended form of the JCT Design and Build Contract 2016 edition (DB 2016). However, the parties may adapt it for use with other building contracts and it requires extremely minor amendments for use with JCT Design and Build Contract 2011 edition (DB 2011).
