What is a scope of work in construction?

A scope of work is the written description of what one party will supply and do on a job. For a subcontractor it also states what is excluded.

Where a scope of work comes from

On a bid, no single page gives a subcontractor its scope. The scope is built from several sources. The estimator reads them all and writes the result into the proposal. The subcontract then sets the final version.

  • The spec sections for the trade.
  • The drawings, schedules and notes.
  • Division 01 and the conditions of the contract.
  • The addenda.
  • The general contractor's bid invitation or scope sheet.

What a clear scope states

  • Inclusions. Each item you supply and install, by spec section.
  • Exclusions. Items you do not carry, named plainly.
  • Clarifications. Assumptions you made where the documents were unclear.
  • Documents. The drawing dates and the addenda your price is based on.
  • Alternates, unit prices and allowances, each as its own line.
  • Terms. How long the price holds, and what you need from others.

Where scope gaps come from

A scope gap is work that no trade carried. Gaps form at the edges between trades. Structural support for hung equipment is a common one. So are power connections, blocking in walls, floor sleeves and final cleaning. The spec can say one trade provides the item while the drawing says by others.

How to write your scope for a bid

  1. List what your spec section requires.
  2. Find each item on the drawings and note where the two differ.
  3. Read the related sections your section names.
  4. Decide what you carry at each edge with another trade.
  5. Write your inclusions, exclusions and clarifications in plain words.
  6. Compare your list with the general contractor's scope sheet.

Scope in your proposal and scope in the subcontract

Your proposal states what you priced. The subcontract can state something broader, such as all work in a section per plans and specs. Compare the two before you sign. Raise each difference in writing.

Takeoff Tool lists what your section requires. It flags where the spec and the drawings disagree.
