Commercial MEP Takeoff Deliverables
Know what to ask for in your estimating package. This guide explains workbook fields, drawing references and scope notes for mechanical, electrical and plumbing bids.
What belongs in an editable quantity workbook?
Agree the required fields before takeoff starts. A quantity-only workbook lists measured work; a priced estimate adds the cost inputs and calculation basis included in the proposal.
| Field | Purpose | Review question |
|---|---|---|
| System, location and cost code | Keep floors, phases and bid packages separate. | Can your team reconcile the totals to its bid form? |
| Description, size and material | Distinguish specification and installation differences. | Are assemblies with different materials or joint methods separate? |
| Quantity and unit | Retain counts, lengths, areas and weights as separate measurements. | Are allowances shown separately from measured quantities? |
| Drawing and revision reference | Trace the line item to the document issue reviewed. | Can a reviewer find the source sheet and relevant addendum? |
| Pricing and labor inputs | Record the agreed quote, rate or allowance basis when pricing is included. | Which inputs are contractor supplied, and which need confirmation? |
Marked-up drawings and scope notes
Request a consistent color legend and system separation for marked-up PDFs. The scope notes should identify reviewed documents, included systems, exclusions, unresolved questions and revision limits. A drawing reference supports review; it does not replace the design team's drawings or the contractor's final bid check.
