Drawing volume and completeness
Sheet count, schedules, details, specifications, legibility and revisions affect the review. Identify the current drawing issue and missing information rather than mixing superseded sheets into the set.
Estimating Fees, Project Scope & Revisions
Know what you are ordering before your bid deadline. The project proposal defines the estimating work, deliverables, fee and proposed delivery milestones.
How an Estimating Fee Is Determined
A small drawing set with dense piping can require more takeoff effort than a larger set with repetitive rooms. Floor area alone does not describe the work. Send the current documents and requested systems so the fee can reflect the scope. This guide explains what to compare in a proposal; it is not a published fixed-price schedule.
Compare Quantity-Only and Priced Estimating Scope
The package name alone does not define the included work. Use these questions when reviewing your proposal.
| Item | Quantity takeoff | Priced estimating support |
|---|---|---|
| Measured quantities | Confirm systems, units and drawing references. | Confirm the same quantity boundaries before pricing. |
| Material costs | Your team normally adds or supplies prices. | Identify supplier quotes, pricing dates and allowances requested. |
| Labor | Do not assume labor hours or wage inputs are included. | Confirm hours, crew rates, burdens and productivity assumptions. |
| Equipment and indirect costs | Specify any equipment quantities needed. | Identify rentals, freight, taxes, subcontractors and indirect-cost allowances. |
| Final tender | Your team prices and assembles its bid. | Your team reviews assumptions, margins and supplier scope before submitting. |

What to Send for a Useful Proposal
- Current drawings, specifications, equipment schedules and issued addenda.
- The requested trades, project location and building or facility type.
- Bid deadline, time zone and desired time for your internal review.
- Any required workbook template, cost codes, alternates or scope exclusions.
- Supplier quotations or company labor/pricing inputs you want considered.
Use the project enquiry form to send your details and optional drawings. For a large set, include an accessible plan-room or shared-folder link in your message. Check the sharing permissions before sending; do not send portal passwords through the form.
Addenda, Revisions and Corrections
A revision should identify the drawing issue, affected sheets and requested changes. New equipment, another floor, an added trade or a changed design can require additional takeoff work. Ask how that work affects the fee and delivery milestone. Keep a correction to the originally agreed scope distinct from an expanded scope; the proposal and project agreement govern the response.
Before authorizing a revision, confirm whether you need a replacement workbook, quantity-delta schedule, updated marked-up sheets or a complete repriced estimate. This avoids comparing totals based on different drawing sets.
Pricing Basis and Contractor Review
A priced estimate should make the source and date of its important inputs visible. Material budgets are different from firm vendor quotes. Labor benchmarks are different from your crew's historical productivity. Where information is unavailable, identify the assumption or allowance instead of treating it as a confirmed supplier cost.
Review equipment quotations for scope, exclusions, delivery and validity. Confirm taxes, freight, waste, access constraints and the final overhead/profit calculation with your own team. An estimate supports a bid decision; it does not guarantee an award or the final installed cost.
Review the Deliverables Before Ordering
The deliverables guide shows illustrative workbook and markup layouts. These are not presented as completed client bids. Compare the format with your own estimating workflow and confirm the actual files included in your proposal. Read the methodology for the published document-review and measurement approach.
Estimating requests can cover plumbing, HVAC, ductwork, mechanical piping or electrical. Confirm any combined package rather than assuming every trade is included.
