Location: Thames Valley – Hybrid, with site and office visits across the region
We are looking to appoint an experienced Senior Estimator to join our Infrastructure team, supporting the delivery of wastewater projects across the Thames Water region.
As a key member of our pre-construction team, you will lead the preparation of competitive and commercially robust tenders, combining strong civil engineering and MEICA estimating knowledge with a practical understanding of project delivery. You will work closely with design, commercial, operational and supply chain teams to develop buildable, cost-effective solutions and support a seamless handover into delivery.
This is an excellent opportunity to play an important role in securing and shaping complex water infrastructure projects, typically ranging from £1m to £30m.
Key Duties
- Lead the preparation of accurate, auditable estimates and cost plans, including first-principles build-ups, preliminaries, indirect costs, risk, opportunities and contingency.
- Manage material and subcontract enquiries across civils, MEICA, process equipment, pipelines, temporary works and specialist operations, undertaking detailed quotation analysis and supply chain negotiations.
- Work collaboratively with design and delivery teams during ECI and two-stage tenders, reviewing drawings and models, challenging buildability and identifying value engineering opportunities.
- Develop tender strategies that consider programme, construction methodology, live asset interfaces, outages, over-pumping, health and safety, carbon and whole-life cost.
- Present tenders at settlement and provide a structured handover to delivery teams, clearly communicating the estimate basis, assumptions, procurement strategy, risks and opportunities.
