Service Details

Service Information and Scope

Problem / Need

Inconsistent quantities across drawings, budgets, and procurement documents make comparison difficult and create omissions or duplication. Without clear measurement rules and references, figures may also be used beyond the level of certainty supported by the source information.

Scope of Work

Review the available drawings and documents, define measurement scope and rules, establish the work breakdown, perform quantity takeoff, and prepare or review a Bill of Quantities with assumptions, exclusions, and references. Outputs can support budgeting or tender documentation from a quantity perspective but do not guarantee final construction cost.

Deliverables

  • Drawing and scope review log

  • Quantity takeoff by work section

  • BOQ with item structure and units

  • Assumption and exclusion register

  • Quantity comparison or checking report where required

Process

We confirm scope, drawing revisions, and intended use; agree measurement rules and work breakdown; measure quantities with source references; conduct completeness and reasonableness checks; and issue the BOQ with limitations and items requiring confirmation as the design develops.

Suitability

Suitable for owners, contractors, estimators, procurement teams, and project teams preparing budgets or tenders, checking third-party quantities, or reconciling quantity information across multiple drawing packages.

Frequently Asked Questions

Common Questions About This Service

What is the difference between BOQ and QTO?
QTO is the process of measuring and compiling quantities from design information. A BOQ organizes those quantities into work items, units, and a structure suitable for estimating, procurement, or contract use.
Can quantities be taken off from incomplete drawings?
Yes, to the extent supported by available information. Assumptions, exclusions, and uncertainty must be stated clearly, with quantities updated when revised design information becomes available.
Does the BOQ include material and labour rates?
Pricing support can be scoped separately where suitable sources and conditions are available. The core QTO/BOQ service focuses on item and quantity integrity and does not guarantee final construction cost.
Can you review an existing BOQ?
Yes. The review may cover the full document or selected risk areas, checking drawings, measurement rules, quantities, and differences together with the assumptions that may explain them.
