Senior Estimator

Building a sustainable tomorrow

We are currently looking for experienced Senior Estimators to join our established Social Infrastructure, Nuclear and Defence pre‑construction team. This business unit covers a diverse portfolio including regional civil engineering projects, flood defence schemes, water and wastewater frameworks, near‑shore marine works, and nuclear and defence infrastructure. As we continue to secure new opportunities across these sectors, this recruitment represents an exciting opportunity to strengthen our capabilities and build on the knowledge and experience within the team.

No two opportunities are the same. From early‑stage budget pricing and Early Contractor Involvement (ECI) contracts through to complex competitive tenders and major infrastructure projects, you will have the opportunity to influence projects throughout their development lifecycle and play a key role in shaping winning solutions. You will join an experienced pre‑construction team bringing together estimating, planning, design management, commercial and operational expertise.

Working closely with project teams, clients, design partners and supply chain organisations, you will help develop safe, buildable and value‑driven solutions for clients across a diverse range of infrastructure opportunities within the Social Infrastructure, Nuclear and Defence sectors.

• Liaising with clients, designers, consultants, quantity surveyors and wider third‑party stakeholders.
• Preparing and administering tender documentation, correspondence, supply chain enquiries and quotations.

• Preparing first‑principles cost estimates using Candy estimating software.
• Participating in bid preparation, review sessions and tender settlement meetings.
• Producing tender summaries, risk and opportunity registers, and communicating estimate details at review and handover stages.
