Defining estimation strategies, assumptions, allowances, exclusions and risk‑adjusted pricing
Driving value engineering and cost optimisation throughout the proposal lifecycle
Ensuring governance, audit readiness and executive‑level sign‑off of all estimates
Supporting structured handover of estimates to delivery teams post‑award

What You’ll Bring
An engineering, quantity surveying or construction management background
8–10+ years’ experience in cost estimation within water, wastewater, civil or infrastructure sectors
Proven leadership of complex, multi‑disciplinary tenders from concept through submission
