Job description

Overview

Bouygues Travaux Publics is specialized in civil engineering and engineering structures and is a world leader in land use planning and sustainable infrastructure construction. The Civil Works Alliance is recruiting a Senior Estimator for the Marine and Tunnelling team to take a lead role on one of the UK\'s most nationally significant infrastructure programmes – Sizewell C.

You\'ll bring strategic commercial thinking, technical depth and the leadership experience needed to help shape a project that will deliver clean, reliable energy to 6 million homes for the next 60 years. This is a senior commercial position with real influence, responsible for building robust, transparent cost models that inform major decisions across planning, design, procurement and delivery.

Responsibilities

• Leading on high-value, first-principles estimates for major work packages, aligned with SZC\'s strategic estimating approach
• Interrogating design proposals, identifying risks and commercial opportunities, and shaping value-driven outcomes
• Overseeing inputs across planning, procurement, commercial and delivery to produce coherent, assured pricing submissions
• Acting as a senior point of contact for internal and external assurance, commercial reviews and client discussions
• Building estimating models using Candy and Cost X, and aligning deliverables to AACE estimating class principles
• Supporting the ongoing development of estimating frameworks, governance and cost maturity across the alliance
• Coaching, mentoring and developing junior team members, and contributing to capability building across the function

Experience and Competencies Required

You\'ll have a strong track record delivering complex estimates for major civil or infrastructure projects, ideally in a Tier 1 contractor environment, and be fully confident working in a collaborative, multi-partner setting. You\'re commercially sharp, methodical, and experienced in aligning estimates with programme-level risk, delivery strategy and schedule. You should be comfortable representing estimating at a senior level, influencing procurement direction or supporting stakeholder assurance.

Experience with Candy, Cost X, and AACE estimating classifications is highly desirable, and professional chartership (e.g. RICS, CICES, ICE, CIOB) is a strong advantage.

This is a rare opportunity to help shape a legacy project that will transform how we power the UK. You\'ll be joining a delivery team backed by the collective strength of Balfour Beatty, Bouygues Travaux Publics and Laing O\'Rourke, bringing together world-class expertise with a shared purpose.
