Schedule of values in a construction contract

A lump-sum construction contract states a total price, but progress payments need a way to connect that total to work completed over time. The schedule of values breaks the contract sum into priced work items. It gives the contractor and the party reviewing payment applications a common structure for tracking what has been completed and what amount is being requested. That is its purpose.

What the schedule contains

A schedule of values usually lists scopes or activities and the value assigned to each. Depending on the contract, it may also show approved changes, work completed in prior periods, work completed during the current period, materials suitably stored, total earned to date, retainage, previous payments, and the current amount due. The total scheduled values should reconcile with the contract sum, including executed changes as the contract requires.

Line items need enough detail to support review without making the schedule unwieldy. A single line for every dollar of the contract gives little information. Hundreds of tiny items may make measurement and review difficult. The right breakdown follows the work, the contract's payment requirements, and the documentation the reviewer needs. The total must reconcile.

How it connects to a pay application

For each billing period, the contractor updates the schedule to show the value of work put in place and any eligible stored materials. The reviewer compares the request with field progress, required supporting records, prior applications, and the contract. If accepted, the approved amount becomes part of the progress payment calculation after applicable retainage, previous payments, and other contract adjustments.

The schedule is a billing framework, not independent authorization to change the scope or price. A new item or revised amount should be supported by the contract's change process. The contractor should preserve a clear trail from an executed change to the updated contract sum and schedule.

A simple example

Suppose a contractor divides a $500,000 contract into site work, foundations, structure, enclosure, and interior finishes. Each line receives a value that reflects its share of the contract. In a later application, the contractor reports percentages or quantities completed by line, along with supporting records. The reviewer can compare the claimed foundation progress with inspections and installed work instead of judging the entire $500,000 contract as one undivided task.

The figures in the schedule do not mean that every dollar assigned to a line has been earned or should be paid immediately. Payment depends on actual progress, acceptable stored materials if permitted, contract requirements, review, and any retainage or other deductions.

Front-loading and other problems

Front-loading occurs when early line items are assigned values disproportionate to the work or cost expected at that stage, so the contractor seeks more money early than the progress justifies. A schedule that is materially front-loaded can expose the owner to loss if work stops after early payments. Review whether values are reasonable against the scope, estimate, procurement commitments, and sequence of work.

• Line-item values do not add up to the contract sum or omit an executed change.
• A broad item combines unrelated scopes and makes progress difficult to verify.
• The application claims work that has not been installed, accepted, or measured as the contract requires.
• Stored materials are billed without the records, protection, or ownership evidence required by the agreement.
• Prior payments, retainage, or approved deductions are missing from the current calculation.
• The schedule changes from one application to the next without an approved basis or reconciliation.

How the schedule differs from related documents

A schedule of values allocates the contract price for progress billing. A project schedule shows the planned timing and sequence of activities. A cost estimate predicts the contractor's costs or bid price. A pay application is the request for payment for a particular period, often prepared using the schedule of values. Retainage is an amount withheld under the contract; it is not a separate work item or a substitute for measuring progress.

Review checklist

1. Check the contract's required submission and payment format before preparing the schedule.
2. Confirm the scheduled values reconcile with the signed contract sum and approved modifications.
3. Use scopes that can be measured and supported in the field.
4. Compare billed progress with inspections, quantities, delivery documents, and other required records.
5. Apply retainage, previous payments, and adjustments according to the contract.
6. Keep each revision traceable to an executed change or documented correction.

For exam questions, connect the schedule of values to progress billing: it divides the lump sum into work items so completed work can be measured and payment requests reviewed. Do not confuse it with the project schedule, and do not treat the allocated value as proof that the work has been performed.
