About the Role
This role seeks a self-motivated candidate to manage engineering projects end-to-end across Thames Water’s operational sites and estate. You will manage all aspects of each CAPEX project, including initial scoping, competitive tendering, contractor procurement, site setup and inductions, health and safety inspections, commissioning, training, and handover to operations teams. The internal job title for this role is ‘Project Engineer’ within the Capital Maintenance Project Team.
You will manage and deliver a portfolio of Mechanical, Electrical, and ICA projects, typically valued between £100,000 and £1 million per project. You will be individually responsible for multiple live projects simultaneously, with additional projects in scoping and tendering phases. You will develop innovative and modern solutions to operational problems, improving site efficiency and delivering value for money.
Working closely with operations teams and contractors, you will scope, define, and cost cost-effective, low-risk solutions. You will oversee a zero-compromise health and safety policy, undertaking monthly audits, and ensure construction complies with in-house policies, wider industry standards, and CDM regulations.
Collaboration with delivery partners and contractors is essential to ensure schemes are delivered on time. You will maintain compliance with Asset Standards, British and International Standards, and professional codes of conduct. Financial forecasting and reporting on the value of work done (VOWD) will be part of your responsibilities.
You will draft, vet, and approve pre-construction information, project programs, risk assessments and method statements (RAMS), and construction phase plans (CPP). You will oversee commissioning, training, and handover of completed projects, ensuring all completion documents, including test certificates, operation and maintenance manuals, health and safety files, and as-constructed drawings, are available and handed over to operations teams.
This is a key role contributing to Thames Water’s mission to build a better future for customers, communities, people, and the planet.
