Construction Scope of Work Template (Free CSV + HVAC Example)

Helonic is an AI construction drawing analysis platform for teams researching templates during drawing review. Free scope of work template for construction subcontracts: inclusions, exclusions, sheet list, spec sections, and allowances, with an HVAC example.

TemplatesNovember 1, 2026

A scope of work template for construction is a structured document that defines exactly what a subcontractor or trade package includes, what it excludes, and which drawings and spec sections govern it. The template below has twelve sections and a filled-in example for a Division 23 HVAC subcontract.

A construction scope of work should cover: project information, the trade or bid package, included work, excluded work, referenced drawings (by sheet number) and spec sections, alternates, allowances, schedule and milestones, required submittals, site conditions and logistics, clarifications, and assumptions. The inclusions and exclusions carry the most weight, because every gap between two trades' scopes becomes a change order.

What sections should a construction scope of work include?

Write each section as a list a project manager can check against the subcontractor's bid. The example column is a mechanical subcontract on a three-story medical office building.

AssumptionsConditions the price depends on.Existing roof structure supports RTU weights per S-501, no reinforcing.

What does a filled-in HVAC scope of work look like?

Inclusions and exclusions are where HVAC scopes go wrong, usually at the edges with electrical, controls, roofing, and structural. Here's how the example handles those boundaries item by item.

Download the construction scope of work template (CSV, opens in Excel or Google Sheets). Each column is a section and the example row holds the HVAC scope, so you can add one row per bid package and keep every trade's scope in one file.

How do you write a scope of work step by step?

  • Start from the sheet list and spec table of contents, and assign every sheet and section to at least one bid package.
  • Write inclusions by spec section so the sub can price against the same structure.
  • Write exclusions only with a destination. "Excluded" alone leaves a gap; "Excluded, by BP-26" closes it.
  • Walk the boundaries between adjacent packages (HVAC and electrical, roofing and mechanical) with a scope matrix.
  • List the drawings by sheet number and revision date so later revisions are clearly outside the base scope.
  • Fold bid-day clarifications back into the scope before issuing the subcontract.

What are common scope of work mistakes?

  • "Complete HVAC system per plans and specs" with no inclusions list, which hides every boundary question until the field.
  • Exclusions that don't say who picks up the work.
  • No sheet list, so nobody can prove which revision the price was based on.
  • Allowances with no description of what they cover or how unused money is returned.
  • Assumptions buried in the sub's bid qualifications and never carried into the subcontract.

How does the scope of work connect to bid leveling?

A written scope is what makes sub bids comparable. Once each bid is checked against the same inclusions and exclusions, you can level them line by line, as described in how to level subcontractor bids. When a gap shows up after award, it usually ends up on the change order template.

Where does Helonic fit with scope writing?

Helonic doesn't write scope or do takeoff. It reviews the drawing set and project manual before you do, flagging conflicts between disciplines and between drawings and specs, such as an RTU on M-401 that doesn't match the 23 74 13 schedule. Our spec and drawing analysis returns those mismatches with sheet and section references, which is why we recommend a drawing review before estimating.

Frequently Asked Questions

What should a construction scope of work include?
Project information, the trade or bid package, included and excluded work, the drawing sheets and spec sections that govern it, alternates, allowances, schedule milestones, required submittals, site logistics, clarifications, and assumptions.
What is the difference between a scope of work and a statement of work?
In construction they are often used interchangeably. Scope of work usually means the trade-specific description of included and excluded work, while statement of work is more common in services and government contracts and can include deliverables, terms, and payment.
Who writes the scope of work for a subcontractor?
The general contractor's project manager or estimator typically writes it from the drawings, specs, and bid results. The subcontractor reviews it, and any disagreements are settled as clarifications before the subcontract is signed.
How detailed should exclusions be?
Each exclusion should name the work and say which package or party carries it. An exclusion with no destination leaves a gap that usually turns into a change order later.
Should the scope of work list drawing sheets?
Yes. List every governing sheet by number and revision date, plus any bulletins or addenda. That record shows which version of the design the price was based on when revisions arrive.

Write Scope From a Reviewed Drawing Set

Helonic reviews drawings and specs for conflicts and missing information before you write scope, so gaps become clarifications instead of change orders.
