What should be included in the first MEP schedule of values?

Include separate lines for submittals, shop drawings or VDC, mobilization if contract-allowed, procurement if the billing procedure allows it, stored materials where permitted, and future installation lines by system.

Can an MEP subcontractor bill submittals and VDC before field installation starts?

Yes, when the contract structure supports it and the work has been performed. Bill those items as completed deliverables with logs, transmittals, or issued-package records that match the schedule-of-values line.

What backup is usually needed for off-site stored materials?

Common backup includes invoices, itemized material records, photos, storage-location details, and any contract-required insurance, ownership, receipt, or lien-related documents.

Should stored materials be billed in the same line as installation labor?

No. Separate lines make the billing package easier to review because the GC can distinguish purchased or stored material from installed work.

How to Structure the First MEP Pay Application Before Field Work Starts

Key takeaways

Separate pre-installation work, procurement, stored materials, and installation into distinct schedule-of-values lines.
Every billed line should have backup that matches the schedule of values.
Stored materials should be billed with project-specific, traceable documentation.
Submittals, shop drawings, and VDC are billed best as completed deliverables backed by logs and transmittals.
A first pay application is easier to review when the package follows the same order as the schedule of values.

Structure the first MEP pay application with separate schedule-of-values lines for submittals, shop drawings or VDC, mobilization if contract-allowed, procurement, stored materials, and field installation. Support each billed line with matching backup so the GC can trace the amount to completed work or purchased material.

A first pay application is easier to review when early document work, procurement activity, and stored materials are not mixed into one installation line. Procore's invoicing and commitment documentation reflects the same core workflow: scheduled values, line items, and supporting records need to align.

Separate early work from installation

Use different schedule-of-values lines for pre-installation work, stored materials, and field installation. That structure gives the reviewer a clear path from the continuation sheet to the backup.

Keep the first billing tied to the contract's billing categories and support requirements. If the contract recognizes mobilization, stored materials, or procurement-related billing, show those items on their own lines instead of burying them inside a broad installation value.

A simple review standard works well:

What work was completed?
What material was purchased or stored?
What document supports the amount?
Where does that amount sit in the schedule of values?

Include reviewable line items in the first draw

The first schedule of values should include only early work that can be documented and reviewed. For many MEP scopes, that means separating document-phase work, procurement activity, stored materials, and installation.

A practical first-draw structure can include:

Submittals and product data
Shop drawings or VDC coordination
Mobilization or startup, if the contract includes it as a billable category
Major equipment procurement, if the billing procedure allows it
Off-site stored materials, if the contract allows billing before delivery
On-site stored materials, if material has already arrived and the contract allows it
Field installation by system, even if those lines remain at zero in the first draw

For review clarity, break future installation into system-based lines instead of a single umbrella line when the contract and billing format support that approach.

Bill submittals, shop drawings, and VDC as completed deliverables

Bill pre-installation work against completed deliverables, not against a vague overhead line. The pay app should show what was submitted, issued, or coordinated during the billing period.

Useful backup for submittals can include:

A submittal register
Transmittal records
A list of submitted, returned, or resubmitted packages
Product data or related package identifiers that match the project workflow

Useful backup for shop drawings or VDC can include:

A drawing or model issue log
Revision dates
Coordination issue records
Issued packages tied to the billed line item

For mobilization or startup, bill against the contract line and keep the backup specific to startup activity. That keeps mobilization from becoming a catch-all category for unrelated early costs.

Support stored materials with traceable records

Stored-material billing should be backed by records that tie the billed line to identified material and its storage location. The first draw is stronger when the continuation sheet, invoice support, and material records match.

Stored-material backup can include:

Vendor or manufacturer invoices
Itemized material lists or packing information tied to the billed amount
Photos of the material or equipment
The storage location
Insurance records, if required by the contract or billing procedure
Ownership, title-transfer, receipt, or lien-related records, if required by the contract

Check the subcontract billing exhibit, any flow-down billing requirements, and the GC's billing checklist before the first submission. Procore's commitment and prime contract documentation and prime contract tools overview reflect how billing records are commonly organized around contract values and supporting documentation.

Organize the package in schedule-of-values order

Arrange the entire billing package in the same order as the schedule of values. A reviewer should be able to move line by line without re-sorting the file set.

A clean first-draw package usually includes:

A cover sheet noting any unusual early-billing items
The pay application form and continuation sheet
One backup section for each billed line item, in the same order as the schedule of values
A stored-material appendix for invoices, photos, and related records
A short note for pending items that are not being billed in the current period

Documents are prepared within the contractor's established review and approval workflow.

Before submission, reconcile the same numbers across the pay app, the schedule of values, procurement records, and support files.

Avoid mixing categories in the first draw

The first draw is harder to approve when cost categories are mixed or the backup does not trace cleanly to the billed line. Keep the structure simple and documentable.

Common problems include:

One broad startup or mobilization line that covers unrelated costs
Stored materials billed inside installation lines
Coordination or submittal billing with no log or transmittal support
Material claims that are not clearly identified to the project
Backup files sent in random order
Pending change amounts mixed into base-contract billing when the billing procedure does not support that approach

If you want to tighten this workflow before the next draw, Tribuild can discuss project-administration support for one upcoming project and help align the schedule of values, procurement backup, and billing package.
