Brownfield Cost Estimating

Brownfield projects demand precision. Complex interfaces, live facilities, and constrained working environments mean that inaccurate estimates quickly translate into cost, schedule, and safety risk.

Genesis helps clients make confident capital investment decisions through reliable, transparent, and execution-focused cost estimating. From life extension and modification projects to major facility upgrades, we help clients understand the true cost of their options before committing capital.

Every brownfield modification is unique. Access constraints, constructability challenges, shutdown requirements, logistics, and operating conditions all materially impact cost and schedule. Genesis brings deep brownfield insight to ensure these realities are built into every estimate — not discovered later.

The result: better investment decisions, optimised execution strategies, and reduced risk.

Prove in Practice

• Supported life extension investment decisions for a mature offshore asset.
• Evaluated brownfield tie-in options using a consistent estimating basis.
• Improved cost confidence for facility modification projects in constrained operating environments.

Real‑world insight, built into every estimate

Experienced estimators apply informed assumptions and challenge incomplete project data to ensure practical, credible estimates.

Genesis cost estimates go beyond quantities and unit rates. We incorporate:

• Constructability and access limitations
• Shutdown and integration considerations
• Environmental and operational constraints
• Local execution and work practices

We estimate the project that will actually be executed, not simply the scope shown on a drawing.

Our estimating approaches are tailored to the maturity, complexity, and risk profile of each project, ensuring the right level of detail at the right time.
