What this trade needs you to recognise
Your starting focus is removal boundaries, protection, disposal and retained work. Before taking responsibility for an issue, show your reviewer that you can trace quantities to the documents, distinguish measured work from allowances and explain unresolved scope.
Day 1 / Set up a controlled handoff
Agree the project code, work package, delivery date, region, units, time zone and named reviewer. Confirm software access using your own authorised account. Use one shared drawing register and one current estimate folder. Keep working copies separate from issued estimates.
Request demolition plans, existing-condition records, surveys and specifications. Record revisions and addenda individually. If a required document is missing, log it before measuring. Access to a folder does not mean its contents are the current tender set.
Day 2 / Map the scope before the takeoff
Write an inclusion list and a list of interfaces with other trades. Link each material or assembly to its schedule or specification reference. Mark unclear boundaries as questions with an owner and deadline. The reviewer should be able to see what you intend to price before you build a large workbook.
Day 3 / Make the quantities traceable
Separate removal quantities by material and location. Mark retained elements, protection zones, salvage and disposal streams. Record what has and has not been observed.
Use consistent item codes and units. Keep the measured quantity separate from waste or other adjustments so another estimator can reproduce the calculation. Save marked plans and identify the drawing reference on each worksheet group.
Day 4 / Price the defined scope
Clarify hazardous-material surveys, isolations, temporary support, occupancy, dust controls and disposal requirements with the responsible specialists. Unknown hazards must not be priced as confirmed ordinary waste.
Use current supplier quotes, agreed company rates or another explicitly approved pricing source. Record the source, date, currency, delivery assumptions and expiry. Show labour basis, allowances and unresolved figures separately. Never turn a calculator’s planning range into a supplier quote.
Day 5 / Review a supervised assignment
Practice brief: A selective strip-out with retained partitions, separate disposal streams and one revised removal boundary.
Use an authorised training or redacted project set. Submit marked plans, quantities, pricing sources, assumptions, exclusions and open RFIs. Check demolition against retained work, review access and protection, and list survey or isolation information still needed. The reviewer records corrections and decides which responsibilities can be delegated next; finishing a checklist alone is not approval to issue a tender.
Choose how the work will be delivered
- App only: use the existing ballpark calculator to explore a planning scenario. Its output is not a completed trade takeoff.
- App plus human: include the app assumptions in a brief for an experienced estimator to review against documents.
- Human only: brief an estimator directly and agree the takeoff method, workbook format, review and issue process.
Compare the three service routes and request scope review. Availability, fees, turnaround and the responsible estimator are confirmed before work is agreed.

Before registration
Prepare relevant past estimating experience and a redacted example of work you may share. Start your EyeSpyR review, then follow the estimator admission steps. A submitted reference remains unverified until checked. No automatic verification or immediate work allocation is promised.
