Concept and order-of-magnitude estimates
Early-stage cost ranges built from comparable projects and elemental rates, with the principal cost drivers identified.
Quantities & Cost
Cost Estimation
Order-of-magnitude estimates at concept, detailed estimates at tender, and cost-to-complete forecasts during execution — each with assumptions and exclusions stated openly.
Overview
Why this matters on your contract
An estimate without stated assumptions is not an estimate, it is a number. The value of a cost figure lies almost entirely in knowing what it includes, what it excludes, what it assumes about scope and market conditions, and how much contingency sits inside it.
We produce estimates at whatever definition the project has reached — from concept, where the answer is a range with clear drivers, to a fully measured tender estimate. During execution we maintain cost-to-complete forecasts so that overruns are identified while there is still time to respond, rather than discovered in the final account.
What you receive
- Estimate workbook with elemental and item-level summaries
- Written basis-of-estimate stating scope, assumptions, exclusions and contingency
- Cash flow projection across the contract period
- Sensitivity analysis on the principal cost drivers
- Periodic cost-to-complete updates during execution
Scope
What the service includes
Every element below is covered as standard. Anything outside it is quoted separately and agreed before we begin.
Detailed tender estimates
Fully measured estimates built from drawings, quantities and analysed rates, item by item.
Preliminaries and indirect costs
Site establishment, supervision, plant standing, insurance, bonds and overhead built up explicitly rather than applied as a blanket percentage.
Cost-to-complete forecasting
Periodic forecast of final cost based on actual expenditure, committed cost and remaining work.
Value engineering
Systematic review of high-cost elements for alternatives that preserve function while reducing cost, each option quantified.
Cost comparison and option studies
Side-by-side costing of design or method alternatives so decisions are made on numbers rather than intuition.
Our Approach
How we do this differently
01
Assumptions are written down
Every estimate is accompanied by a basis document. Six months later, nobody has to reconstruct what the number meant.
02
Contingency is stated, not buried
You can see exactly how much risk allowance sits in the figure, which means you can make an informed decision about carrying it.
03
Forecasts arrive while they are useful
Cost-to-complete is updated on a fixed cycle, so an emerging overrun surfaces with time left to act on it.

+977 1 4538 720At concept, typically within plus or minus twenty to twenty-five percent, and we say so explicitly. Accuracy improves as design definition improves; presenting an early estimate as precise would be misleading.
Yes, using elemental rates and comparable project data, with the assumptions made for undefined scope stated clearly so they can be revisited as the design develops.
If the contract period warrants it, yes — as a separately identified allowance rather than absorbed into the rates, so it remains visible and can be tested against the actual contract escalation mechanism.
