Every price starts with how much there is.
Before anyone can price a building or a road, someone has to work out how much of it there is. On a traditional tender the client or consultant does it. On design and build, functional tenders and early involvement, the contractor does, from drawings, specifications and the model, at whatever maturity the design has reached.
01
Scope read in parts
Quantities taken off one drawing while a specification or addendum changes them somewhere else.
02
Take-off takes up time
Manual measurement and structuring absorb the days that should go to pricing and strategy.
03
Hard to check
No fast way to review an estimate against the full document set, or against how you priced a similar job before.
Everything the estimate needs, mapped to how you work.
Volve follows the estimating workflow, from the quantities in the drawings to the review before the number goes out. Each step structures the scope, does the reading and shows its source, so the judgement stays with your team.
Quantities extracted and structured by work package and discipline
Take-off checked against the drawings and the model
Each figure linked to its source drawing or specification
Scope organised into work packages for your project type, such as earthworks, concrete and steel
Requirements and quantities held against each package
Clarifications raised before they turn into pricing risk
Surface scope that is not yet reflected in the price
Flag quantities that differ from the drawings or model
Check valuations against the contract baseline and changes
From tender documents to a traceable BoQ.
Measure and count what is there. Estimate and flag what isn’t. You decide how each gap closes.
Measured: taken off the drawings or model, traced to the sheet
Counted: items counted from schedules or drawings
Conditional: measurable once an open point is answered
Not quantified: needs your input or an assumption
What estimators ask Volve to do.
Tasks from a normal tender week. Every answer comes with its source.

Top 7 quantity gaps in construction tenders

Checklist
How to check a bill of quantities
Ten checks before you trust the numbers, whoever produced them.
Insight · the method
How Volve builds a traceable bill of quantities
Four kinds of quantity, and who closes each gap.
Numbers you can defend
Every quantity shows the drawing or clause it came from.
The same method every time
Your package structure, standard and checks on every tender.
Time back for judgement
The take-off is done. The team’s hours go to the missing quantities, rates, risk and price.
One use case, several roles.
Estimating, commercial and bid teams work from the same structured scope and the same numbers. Findings and sign-offs are shared and traceable, so the estimate the bid team builds is the one the project team inherits.
Estimators
Build the estimate on structured quantities, each one traced to its source drawing or clause.
Quantity surveyors & commercial
Review coverage and valuations against the documents, and see what an addendum has changed.
Bid & procurement
Price the bid and compare supplier offers against the same structured scope.
Within the same day, we have a first version of all major quantities taken off the client material.
