How to Create and Manage a Construction Submittal Schedule

You’re six weeks into a commercial build. The structural steel is ready to go. The fabricator’s been standing by. And then someone checks the submittal log and realizes the shop drawings are still sitting with the engineer of record because nobody set a hard review deadline, and nobody followed up. Three weeks of float, gone. The schedule absorbs the hit. The owner asks questions. And when you dig into the postmortem, it always comes back to the same thing: the submittal schedule wasn’t built tight enough, and nobody owned the tracking.

That’s what this guide is about. Not a high-level overview of what submittals are you already know that. This is about how to build a submittal schedule that’s actually sequenced against your construction schedule, how to assign real accountability at every handoff, and what to look for when your Excel log stops being enough.

Why the Submittal Schedule Is the Most Underbuilt Document in Preconstruction

Most GCs know they need a submittal schedule. Fewer treat it with the same rigor they give the CPM schedule or the budget. That’s a costly oversight because a poorly sequenced submittal process is one of the most reliable ways to push your substantial completion date. The submittal schedule does three things: it identifies every required submittal for the job per the contract, locks in when each one gets delivered, and gives the whole team a shared timeline for the review and approval process.

But here’s the part nobody says out loud enough on AIA contracts, not having a submittal schedule also strips your ability to claim time and money when a design team review drags past a reasonable window. Without it, the architect has no contractual obligation to respond within any specific timeframe, and you have no ground to stand on when arguing that the delay cost you schedule days. The submittal schedule isn’t just a project management tool. It’s a contractual protection mechanism. Treat it like one.

How to Build a Construction Submittal Schedule 

Start with the spec book 

The submittal schedule lives or dies on how thoroughly you pull items from the project specifications. On a mid-size commercial project, you’re typically looking at 200–600 individual submittal register items by the time you’ve done a complete pull. That number surprises a lot of teams the first time they do it right. Most project engineers are solid on the obvious divisions structural, mechanical, electrical. The misses happen in the supporting divisions: specialty coatings, acoustic treatments, access control systems, elevator finishes. Every spec section that includes a “Submittals” paragraph is generating required items. Work through all of them before you declare the log complete.

Sequence submittals against the construction schedule 

This is where most submittal schedules fall apart. Teams build the submittal log and then try to slot it into the project schedule as an afterthought. The sequence should run the other way: start with your need-on-site dates, work backward through fabrication lead times and review windows, and set submittal due dates that give you actual buffer.

Long-lead items need to drive the front end of your schedule. If your structural steel has a 14-week fabrication lead time and the frame is scheduled to start in week 10, that shop drawing submittal needs to go out in week one not when the kick-off meeting wraps up in week three. Submittals on the critical path get prioritized above everything else. That’s not a preference, it’s a rule.

Calculate review windows honestly and plan for one resubmittal round

Standard review windows run 10–14 business days for most submittals. Complex mechanical or structural items often need 21 days, especially when routing through multiple reviewers. Here’s what catches teams: most schedules account for one clean approval and nothing else.

In reality, for anything involving custom fabrication or detailed shop drawings, a resubmittal round is normal, not exceptional. A rejected curtain wall submittal that requires redesign coordination and a full re-review cycle can eat four to six weeks before you get a stamp. Build that round into the schedule as a planned event not a contingency buried in the float.

Also worth pushing for wherever your contract allows: parallel review. Sending a submittal package to the architect and structural engineer simultaneously rather than sequentially can shave 10–14 days off a single approval cycle. On a complex project with dozens of interdependent packages, that adds up to real schedule recovery.

Put names on every line not just company names

The biggest accountability failure in submittal tracking is vagueness. “MEP Sub responsible” means nobody is responsible. When you’re building out your schedule, name the actual contact at each firm who owns preparation, the person at your office running the GC review, and the specific reviewer at the design team who’ll be stamping it.

When something goes overdue and it will you want to be picking up the phone and calling a person, not composing a “following up on the submittal” email to a generic project inbox.

Get written sign-off from the design team before construction starts

Once the schedule is finalized, get the architect and key consultants to formally acknowledge it. That acknowledgment becomes your documentation if a design-team delay later triggers a schedule impact claim. Without it, you’re in a he-said-she-said conversation with no paper trail and a frustrated owner wanting to know why the project is behind.

What a Functional Submittal Log Actually Looks Like

The submittal log is the live tracking document that sits underneath the schedule. Every entry should carry at minimum: spec section number, submittal description and type, priority level, responsible subcontractor, GC submittal manager, design-team reviewer, required submission date, required approval date, and current status. Here’s a sample reflecting what this looks like on a mid-rise commercial project:

The log is only useful if it’s current. Make it a standing agenda item at every project meeting not a document that gets refreshed when something breaks.

Deferred Submittals: The Schedule Risk Nobody Talks About

A deferred submittal is one the design team explicitly allows to be submitted after permit issuance usually because the specialty system can’t be fully designed until the base building scope is locked. Fire suppression layouts, post-tensioning designs, and complex glazing systems commonly fall here.

The trap is that teams treat deferred submittals like they’re genuinely low-priority. They’re not. A deferred submittal for a building automation system might not be contractually due until month four but if it comes back rejected and requires a full redesign cycle, you’ve just moved your occupancy date. Nobody’s happy about that conversation.

Track every deferred submittal with identical rigor to your standard log. Set a hard internal deadline that gives you real buffer before the affected scope starts. And get formal written confirmation from the A/E that the item is officially deferred not just a verbal acknowledgment from a coordination call.

When the Spreadsheet Stops Working

For projects under 150 submittals with a tight team, a well-maintained Excel log can hold up. Once you’re north of that multiple subs, parallel review chains, concurrent packages the manual process starts creating risk.

The core problem isn’t the spreadsheet itself. It’s that spreadsheets don’t notify anyone. They don’t flag when an item is overdue. They don’t tell you whether the version the architect is reviewing matches what the sub submitted last Tuesday. And when a review stalls, figuring out where exactly it got stuck still at the sub, sitting in your internal queue, or parked with the design tea requires email archaeology that nobody has time for mid-project.

The features worth prioritizing when you’re evaluating platforms:

Automated notifications — reviewers get flagged when items are assigned or overdue. Nothing sits waiting because someone missed an email chain.

Parallel review routing — the ability to send a submittal package to multiple reviewers simultaneously and track each response independently.

Version control — every revision and markup tied to a specific reviewer and date. Everyone is always working off the current document.

Schedule integration — submittal milestones and construction milestones in the same system, so a slipped approval date automatically surfaces as a schedule risk rather than staying buried in a separate tracker.

Custom status fields — “Approved as Noted,” “Revise and Resubmit,” and whatever else your contract language requires, mapped to your actual workflow.

The right platform doesn’t just log submittals. It connects approvals directly to your procurement process so when a shop drawing gets stamped, the next step in your material ordering workflow triggers automatically, without a project engineer manually bridging the gap.

The Mistakes That Actually Cause Schedule Delays

Starting the submittal list too late: The list should be pulled and the schedule drafted within 7–14 days of contract award. Teams that wait until the project kick-off meeting have already burned their buffer on anything with a 12-plus week lead time.

Scheduling based on old lead times: Custom switchgear, specialty glazing, and long-lead mechanical equipment have been running 16–28 weeks across many markets. If you’re building your submittal schedule around what lead times looked like a few years ago, you’re going to get surprised call your vendors before you finalize the schedule.

Treating resubmittals as rare events: For complex shop drawings, one resubmittal round is the norm. Building your schedule as if every item will sail through on first submission is optimistic in a way that costs you real schedule days.

Not running submittals as a standing agenda item: When submittal status only gets reviewed after something breaks, it’s already too late to recover the schedule cleanly. Keep it on the weekly meeting agenda it takes 10 minutes and catches problems while they’re still manageable.

Keeping communication siloed: Subcontractors typically have limited visibility into the broader submittal plan. GCs who share the full schedule with their subs and hold a regular submittal coordination meeting across trades catch interdependencies before they become delays. The architect often wants to review adjacent systems simultaneously. If two different subs are responsible for those systems and don’t know about the timing coordination, someone’s going to miss it.

If your submittal tracking is still managed through email threads, delays are almost inevitable.

Frequently Asked Question

What’s the difference between a submittal log and a submittal schedule?

The submittal log is the master tracking document —very required submittal, its current status, revision history, and responsible parties. The submittal schedule is the timeline layer: when each submittal needs to be submitted, reviewed, and approved, tied to the actual construction schedule. In practice, a well-built submittal log incorporates schedule columns so both functions live in the same document.

When should the GC build the submittal schedule?

Right after contract award, before construction starts within 7–14 days of award. Any delay creates pressure on long-lead procurement and reduces your contractual leverage if design-team delays later cause schedule impact.

What is a deferred submittal and how should it be handled?

A deferred submittal is one the design team allows to be submitted after permit issuance, typically for specialty systems that can’t be fully designed until the base building scope is set. It should be tracked with the same rigor as standard submittals, with formal written acknowledgment from the A/E and a hard deadline tied to when the affected scope is scheduled to start.

What happens if a submittal gets rejected?

The contractor prepares a revised submittal addressing the reviewer’s specific comments and resubmits through the same approval chain. The resubmittal starts a new review clock which is exactly why building at least one resubmittal round into your schedule is a baseline practice, not optional.

What’s a submittal package and when does it make sense?

A submittal package groups closely related submittals into a single transmission. An electrical contractor might submit a light fixture package covering all interior fixture types rather than routing 25 individual items through the approval chain separately. Packages reduce administrative load for reviewers and work best when the items are interdependent and need to be evaluated together.
