Estimator – Cost Intelligence (Water Sector & Major Infrastructure)
Cumming Group is an international project and cost management consultancy delivering innovative solutions in construction, real estate, and infrastructure. Through collaboration, transparency, and performance excellence, we support some of the UK’s most respected clients across regulated utilities and major capital programmes.
The Role
We are looking for an Estimator to join our Cost Intelligence team, supporting water-sector and major infrastructure projects. This role provides an opportunity for an experienced estimator to contribute to the development of early-stage cost estimates on complex, regulated infrastructure programmes.
The role spans both detailed and higher-level estimating activities requiring a strong understanding and practical experience of top-down and cost-intelligence-led estimating approaches, and an ability to apply these appropriately alongside traditional methods.
Key Responsibilities
- Prepare quantities and cost build-ups from drawings, specifications, and early design information.
- Support the development of capital cost estimates for water and major civil infrastructure projects across feasibility, options, and pre-tender stages.
- Apply asset-based Cost Breakdown Structures (CBS) to structure, normalise, and benchmark estimates.
- Interpret designs in line with the relevant level of CBS for pricing.
- Carry out technical and commercial appraisal of subcontractor and supplier quotations.
- Produce analytical estimates, including assessment of construction plant, temporary works, and delivery methodology.
- Use estimating software and Excel-based cost models to prepare accurate and auditable estimates.
- Contribute to top-down and parametric estimating where appropriate, using cost intelligence and historical outturn data.
- Support cost risk and uncertainty analysis, including contingency and optimism bias considerations.
- Support day-to-day delivery on Cost intelligence projects.
- Support knowledge capture, cost intelligence development, and sector initiatives.
- Ensure compliance with client governance, company policies, and quality standards.
- Commit to professional development and continuous improvement.
