Chief Estimator – Water & Sewer Infrastructure
We are seeking an experienced Chief Estimator to lead the cost planning and tendering function for major water and sewer infrastructure projects. This role will oversee the preparation of accurate, commercially sound estimates for complex civil construction works, including pipelines, pump stations, treatment facilities, reservoirs, drainage networks and associated utilities. You will provide senior leadership across the estimating process, ensuring submissions are competitive, compliant and aligned with project delivery requirements.
Key responsibilities include managing end-to-end estimating activities from early contractor involvement and concept design through to final tender submission. You will review drawings, specifications, scopes of work and contract documentation; develop detailed cost plans, bills of quantities, rates and construction methodologies; and obtain and assess supplier and subcontractor quotations. The role will involve identifying commercial risks, exclusions, assumptions and value-engineering opportunities, while working closely with project managers, engineers, planners, procurement teams and senior leadership. You will also mentor estimators, establish consistent estimating processes, contribute to bid strategy and present estimates and recommendations to internal stakeholders.
Applicants should have substantial estimating experience within water, sewer, utilities or heavy civil infrastructure, together with a strong understanding of construction methods, resource planning, materials, plant, subcontractor engagement and relevant contract conditions. A proven track record of leading successful tenders for major infrastructure projects is essential. You will need excellent analytical, negotiation and communication skills, strong commercial awareness and the ability to interpret technical information and manage multiple deadlines. Proficiency with estimating, scheduling and document management software is expected, along with a relevant qualification in quantity surveying, construction management, engineering or a related discipline. The successful candidate will be proactive, highly organised and confident working in a collaborative, deadline-driven environment.
