An accurate site survey and quantity takeoff are the preconditions of a sound budget and a fair tender in electrical works. Missing quantities come back during execution as scope growth and contract disputes; inflated quantities load the investor with unnecessary cost. This study establishes the true quantity of the work at work-item level and in a verifiable form.
Miratek carries out takeoff work not only from drawings but, where needed, together with a site survey. Cable routes, containment systems, panel layouts, and room schedules are verified in place; differences between the drawings and the site are reflected in the takeoff. Deliverables are handed over in a format directly usable in the tender file, the budget study, and progress payment control.
Prepared by an engineering team that is also active on the contracting side, the takeoffs account for the real consumption rates encountered in execution. That keeps the gap between estimate and actuals to a minimum.

How We Work
Document Review
Drawings, room schedules, and technical specifications are reviewed to define the takeoff items.
Site Survey
Routes, installation conditions, and differences between the drawings and the site are identified in place.
Quantity Takeoff
All work items are measured from drawing and survey data and calculated item by item.
Check and Verification
Takeoffs are cross-checked; critical items are verified by a second reviewer.
Survey Summary and Handover
The quantity schedule and survey summary are delivered in a format usable in budgeting and tender processes.
Scope of Work
- Work-item quantity takeoff from electrical drawings
- Site survey and as-is condition assessment
- Room schedule and drawing consistency check
- Preparation of survey summaries and item code definitions
- Pre-tender takeoff verification and second opinion service
- As-built record and progress payment quantity control during execution
Frequently Asked Questions
Is the takeoff produced only from drawings?
The takeoff from drawings is the baseline, but for existing buildings and renovation works a site survey is essential. If route and room differences between drawing and site are not reflected in the takeoff, scope growth during execution becomes inevitable. On critical projects the two methods are therefore used together.
We already have a takeoff — can you check it?
Yes. The existing quantity schedule is reviewed item by item, missing or duplicated items are identified, and a variance report is prepared. This check matters especially before tender, so that bids can be compared on a sound basis.
Can the takeoff deliverables be used in the progress payment process?
They can; because the quantity schedules are prepared with item codes and unit definitions, they can be compared directly with the executed work at each progress payment period. On request, as-built record and progress payment quantity control throughout execution is also included in the service.
