Quantity Surveying & Construction Cost Services


Bank Drawdown & Cost to Complete Reporting

We provide accurate, independent assessments of work completed and forecast costs to support bank funding releases and financial oversight. These reports are trusted by lenders and essential for staged finance arrangements.

Construction Cost Studies & Estimates

Our detailed cost estimates give you clarity and confidence at the planning stage. From high-level feasibility budgets to detailed trade-by-trade costings, we help you make informed decisions before work begins.

Feasibility Studies

Understand the true potential of your project before committing. Our feasibility studies examine cost, risk, and viability to ensure your investment aligns with market and project realities.

Cash Flow Forecasting & Reporting

We prepare realistic and reliable cash flow forecasts to help you manage financial planning over the lifecycle of your project. Stay ahead of cost pressures and avoid budget surprises.

Cost to Complete Reports

Know where your project stands. Our cost to complete reports provides an updated view of remaining expenditure, identifying any variances and allowing you to act early to mitigate overruns.

Procurement, Contract & Claims Support


Tender Management & Tender Analysis

We prepare comprehensive tender and contract packages, oversee the tendering process, and conduct detailed comparisons and evaluations of bids. This ensures you select the right contractor at the right price.

Review of Extension of Time Claims

Disputes over delays can be costly and disruptive. We offer an independent review of extension of time claims, providing transparent analysis to support fair outcomes for all parties.

Final Account Review & Negotiation

As your project concludes, we ensure all accounts are accurately settled. Our final account reviews help close out costs cleanly and efficiently, with professional negotiation support where needed.

Planning & Programming


Critical Path Programming

Project timing is everything. We create and monitor critical path schedules to ensure all elements of your build are properly sequenced and achievable — helping to avoid costly delays.

Scope of Work Development

Clear documentation is essential to successful delivery. We help define your project’s scope in detail, providing contractors and consultants with a clear understanding of expectations, deliverables, and responsibilities.
