Definition

Scope of work (SOW) is the written description of what is included in the contract—tasks, deliverables, materials, and boundaries. It defines what the contractor will do (and by implication what is excluded). Clear scope reduces disputes; scope creep is when work is added without a formal change order.

Why It Matters

Ambiguous scope leads to “I thought that was included” disputes. A well-defined SOW supports accurate estimating, change order management, and progress measurement. Contractors should tie their estimate and schedule of values to the SOW so billing and completion tracking align with the contract.

Field Example

SOW: “Furnish and install interior paint for Areas A and B per spec 09 91 00; two coats; owner-supplied color. Excludes trim and ceilings.” When the owner asks for ceilings, that’s out of scope—handled as a change order. The SOW makes the boundary clear.

Calculation / Formula (if applicable)

Not applicable. Scope is descriptive. It can be broken into line items or phases for billing (schedule of values) and for tracking completion.

Software Application

Store or link SOW document to the job. Optionally break scope into phases or SOV line items for billing and progress. When change orders are created, reference what is in vs. out of scope. Use scope as the basis for job budget and progress completion %.

Tooltip Version

Scope of work is the written description of what’s included in the contract; it defines the boundary so extras are handled as change orders.
