The objective of the guide is to provide advice on successful implementation of any large construction contracts related to public health engineering works. The following key steps must be adhered to, to ensure a successful outcome to the contract management process: 1) Planning the full contract document, 2) Procurement - Selection of contractors through tender process, 3) Implementation - Advice and supervision during the implementation phase and 4) Completion – Supervising the handover process. It is essential that the person managing the contract process, not only follows the key process steps, but also liaises closely with the project technical team, the logistics team, the Oxford logistics team and the Oxford PHE Advisory team.This Technical Brief provides an introduction to contracting out PHE works and the subsequent management of such contracts for engineers, logisticians and project managers.
