Job Description

We are looking for a Project Manager to lead the procurement of a significant main works package for an upcoming "design and build" construction project, with potential to grow into a future role on the main construction works.

As the Project Manager, you will support the Preconstruction and Design Lead in the procurement and onboarding of the main works contractor, and other supporting subcontract packages, for the design and build of a significant new facility. These activities will need to ensure that successful procurement of contractors takes into consideration that the works will be taking place in a highly regulated environment, in close proximity to a number of key stakeholders and must ensure that the successful companies are competent to operate in this environment. You will manage the input of specialist stakeholders and commercial colleagues to ensure a transparent and fair tender process, ensuring compliance with public sector procurement best practice.

This role is based remotely, with some flexibility on when and how often visits to site are made. The role is primarily a full-time role, but this can be discussed. Candidates must be able to obtain security clearance.
