Construction Submittals: The Complete Guide to Types, Process, and Approval

What are construction submittals?

A submittal is any documentation the contractor must furnish to demonstrate that the work will comply with the contract documents — most often the project specifications. It is a verification step: the design team gets a structured chance to confirm that what the contractor plans to buy and build aligns with the design intent before any money is committed to fabrication or installation. Catching a mismatch on paper costs a review cycle; catching it after a custom assembly is fabricated costs real money and real schedule.

Because the specific requirements vary from job to job, "submittal" is a broad umbrella rather than a fixed category. What has to be submitted, and when, is spelled out section by section in the specifications, which is why reading the spec carefully — and organizing the package to match it — matters so much.

Types of construction submittals

Most submittals fall into three familiar categories, with additional items layered on for larger or public projects.

• Shop drawings — contractor-, subcontractor-, or fabricator-prepared drawings that translate the design into the detail needed to fabricate, assemble, and install a component. They show how the builder intends to execute the design, not the design itself.
• Product data — manufacturer cut sheets and specification sheets for the proposed products, marked up to identify the exact model, options, finishes, and performance ratings being furnished and to show conformance with the spec.
• Samples and mockups — physical examples of materials, finishes, or assemblies that establish the tangible standard the installed work will be judged against.
• Other required submittals — federal work under the FAR and many large private jobs add safety plans, project schedules, coordination drawings, engineering calculations, warranties, and closeout documents.

The submittal process, step by step

The workflow is a loop that repeats for every required item until it is approved. Understanding each hand-off is the key to keeping it moving.

• Prepare — the subcontractor or supplier compiles the shop drawings, product data, or samples the spec requires, and marks them up to show the exact products being furnished.
• Submit — the general contractor reviews for completeness, stamps its own approval to confirm it has coordinated the item, logs it on the submittal register, and forwards it to the design team.
• Review — the architect or engineer of record reviews for conformance with the design concept and the contract documents, then returns the item with an action stamp.
• Return and act — an approved item moves to procurement and fabrication; a "revise and resubmit" or "rejected" item goes back to be corrected and run through the loop again.
• Distribute — approved submittals are logged and distributed so the field, procurement, and the record set all reference the same confirmed selections.

Who is responsible for construction submittals?

Preparing and furnishing submittals is the contractor's responsibility. The prime contractor, with its subcontractors and suppliers, compiles the drawings, gathers the product data, and provides the samples — and because it controls the means and methods of construction, it remains responsible for the accuracy and completeness of what it submits, including dimensions, quantities, and field conditions.

The design team's review is deliberately narrower: it checks for conformance with the design concept and the information in the contract documents, not for construction accuracy. An architect's stamp approves the design intent; it does not transfer responsibility for field accuracy away from the contractor. Keeping that boundary clear prevents a great deal of misplaced expectation when an issue surfaces later.

What the review stamps mean

The design team returns each submittal with an action that tells the contractor whether it can proceed. Exact wording varies by firm, but the intent is consistent.

• Approved / No Exceptions Taken — proceed; the submittal conforms.
• Approved as Noted / Reviewed as Noted — proceed, but incorporate the reviewer's marked corrections; a resubmittal is usually not required.
• Revise and Resubmit — do not proceed; correct the noted items and submit again for another review.
• Rejected — the submittal does not conform; a new submittal is required.
• For Record Only / Not Reviewed — logged for the record, typically because review of that item is not the design team's responsibility.

Managing submittals without the bottleneck

Two tools keep the process under control. The submittal register (or submittal log) lists every required submittal with its spec section, responsible party, and current status, so nothing falls through the cracks. The submittal schedule sequences those items against long-lead procurement, so the submittals that gate the longest lead times get prepared and approved first.

The failure mode is almost always the same: a critical submittal is prepared late or bounces through extra review cycles, and by the time it is approved, the fabrication window has slipped. Establishing both the register and the schedule at the start of the project — and protecting the long-lead items — is what keeps a paperwork step from turning into a construction delay.

How Submittal.app speeds this up

The concepts are simple; the execution is where teams lose hours. Assembling a submittal package traditionally means hunting down the right manufacturer cut sheets, matching part numbers by hand, reading the spec line by line to check conformance, and formatting everything into a clean, reviewable document — repeated across dozens of spec sections, where one transposed catalog number can trigger an avoidable rejection and another review cycle.

Submittal.app's Submittal Builder is an AI agent that takes on that grind: it reads a schedule or spec section, locates the correct cut sheets and product data, matches part numbers, compares the proposed products against the specification, flags deviations, and assembles a formatted, review-ready package — cover page, table of contents, organized documents — in minutes instead of days. Because the same confirmed catalog numbers carry through from spec to submittal to quote to purchase order, the details stay consistent across the whole procurement chain. It is free to start at user.submittal.app/signup/builder.
