Turnaround Times for Glazing Shop Drawings: What to Expect
Last Updated: October 23, 2026
Quick Summary
Most glazing shop drawings take two to six weeks from receipt of complete design documents to approved status, with drawing production often the shortest part and review cycles consuming the rest. A mid-rise curtain wall package of 50-150 openings typically runs four to six weeks, while curved or bespoke façades of 100+ openings commonly land at six to ten weeks.
- Standard window wall packages under 50 openings draft in one to two weeks.
- First review by the consultant or architect takes five to fifteen business days.
- Aim to resubmit markups within five business days to avoid adding days to the program.
- Lock window and door schedules before drawing production starts to prevent rework.
- Split large packages so standard window wall review runs parallel to curved façade review.

Why Glazing Shop Drawing Turnaround Decides Your Program
Glazing shop drawings are the fabrication-ready documents that translate an architect's design intent into buildable window, door and façade details.
Ask any project manager what derails a façade program and you'll hear the same answer. It's rarely the glass itself.
At BluePrint Facade, we produce these drawings daily for window wall, curtain wall and curved window systems.
Below, we break down realistic turnaround windows, the full approval timeline, and the practical steps that keep a drawing package moving.
Typical Turnaround Times for Glazing Shop Drawings
Most glazing shop drawing packages take between two and six weeks from receipt of complete design documents to approved status. The drawing production itself is often the shortest part. Review cycles consume the rest.
Treat any single number as a rough guide only. A standard window schedule on a low-rise building moves faster than a curved façade with structural glazing and custom framing.
By Project Type and Package Size
Here's how turnaround typically breaks down across common project profiles:
| Project Type | Package Size | Production Time | Full Approval Cycle |
|---|---|---|---|
| Standard window wall, low-rise | Under 50 openings | 1-2 weeks | 3-4 weeks |
| Mid-rise curtain wall | 50-150 openings | 2-3 weeks | 4-6 weeks |
| Curved or bespoke façade | 100+ openings | 3-5 weeks | 6-10 weeks |
| Multi-building package | 200+ openings | 4-6 weeks | 8-12 weeks |
Small, repeatable packages move quickly because the detailing is familiar. Curved window design is the opposite. Every radius, mullion transition and glazing thickness needs individual attention, and that time is hard to compress.
The Shop Drawing Approval Timeline, Stage by Stage
The full approval timeline runs through six stages, from document receipt to final approved drawings. Each stage has a realistic duration, and skipping the front-end checks pushes delay into the review cycle instead. The critical distinction most guides miss is that only stages two and three sit in the fabricator's control. Stages four and five belong to the reviewer, and they are where the calendar usually stretches.
Stage 1: Document receipt and review (2-5 days). The fabricator checks that architectural drawings, specifications and the window schedule are complete and consistent. A complete intake at this stage is the single biggest predictor of a short total timeline. If the window schedule is still being revised, stop here rather than drafting against a moving target.
Stage 2: Drawing production (1-4 weeks). Elevations, section cuts, dimensions and opening schedules are drafted against the design intent. Duration scales with opening count and system complexity: a standard window wall package under 50 openings typically drafts in one to two weeks, while a curved or bespoke façade with 100+ openings commonly takes three to five weeks. Custom framing, structural glazing and non-standard mullion transitions each add drafting days that cannot be compressed by working faster.
Stage 3: Internal quality check (2-4 days). A second set of eyes catches dimension conflicts and missing details before submission. This is the cheapest delay in the whole program, a day spent here routinely saves a full review cycle of five to fifteen business days.
Stage 4: First review by the consultant or architect (5-15 business days). This is where most programs slip. Reviewer workload drives the timeline more than drawing quality.
Stage 5: Revision cycle (3-10 days per round). Markups are addressed and resubmitted. Two rounds is normal; three signals a coordination problem upstream. The total revision time is multiplicative, not additive: two rounds at seven days each adds a fortnight to the program, and each round also re-enters the reviewer's queue for another five to fifteen business days. A package that needs three review cycles can easily consume six to eight weeks in review alone, regardless of how fast the drawings were drafted.
Stage 6: Approval and release to fabrication (1-2 days). Final drawings are stamped and issued for production. Keep this short by having the fabrication order and glass procurement ready to release the moment approval lands.
A realistic total for a mid-rise curtain wall package of 50-150 openings is therefore four to six weeks: roughly two to three weeks in production and internal check, plus two to three weeks across the first review and one revision round. A curved or bespoke package of 100+ openings commonly lands at six to ten weeks once two revision rounds are allowed for. The Australian Building Codes Board sets the performance framework these drawings must satisfy, so build compliance checking into stage two rather than discovering gaps at review.
Glazing Shop Drawing Submission Requirements That Prevent Rework
Complete submission packages get approved faster. That sounds obvious, but incomplete submittals are the single most common cause of a rejected first review.
A submission that survives first review typically includes:
- Fully dimensioned elevations and section cuts for every system
- An opening schedule listing every window and door with sizes and types
- Glazing and framing specifications, including glazing thickness and performance data
What most guides miss is the deviation register. Reviewers spend less time on a drawing that openly states where it departs from the specification. Hidden changes get caught eventually, and they cost a full revision cycle when they do.
Window Schedule Coordination: The Hidden Driver of Delay
Window schedule coordination is the discipline of keeping the architectural schedule, the shop drawings and the fabrication order aligned.
In practice, this is where late decisions hurt most. A client changes a door type in week three, the schedule updates, but nobody tells the fabricator.
Coordination habits that hold the timeline:
- Lock the window and door schedules before drawing production starts
- Run a line-by-line comparison of schedule against drawings before every submission
- Route any design change through one nominated coordinator, not three separate email threads
The National Construction Code ties performance requirements to the specific systems in your schedule, so a schedule change can carry compliance consequences.
Shop Drawing Revision Management and Review Cycles
Shop drawing revision management is the process of logging, addressing and resubmitting reviewer markups without losing track of versions. Good revision control is the difference between two clean cycles and five messy ones, and because each cycle re-enters the reviewer's queue, the difference is measured in weeks, not days.
A workable revision system needs four things:
- A revision number on every sheet, incremented on each resubmission
- A markup response sheet that answers every reviewer comment in writing
- A single current-issue set, with superseded drawings clearly marked
- A revision log shared with the general contractor and project manager
How Review Cycles Compound the Schedule
Fabricator drafting time and architect or engineer review time are separate schedule dependencies, and conflating them is the most common estimating error. A single review round typically consumes five to fifteen business days in the reviewer's queue. Your own markup turnaround adds three to ten days per round on top. So the total revision time is roughly:
(reviewer days + your markup days) × number of rounds
Two rounds at an average of ten reviewer days and five markup days each is thirty business days, six working weeks, before approval. Three rounds pushes it to nine weeks. This is why a package that drafts in two weeks can still miss a twelve-week program if the reviewer is slow or the markups are heavy.
A simple way to estimate and communicate this: build a milestone tracker with five columns, drawing number, revision, date submitted, reviewer response due, and date returned. Populate the reviewer response due date from the consultant's stated review window at kickoff. When the returned date slips past the due date, you have evidence to escalate rather than a vague complaint. Share the tracker with the general contractor so the schedule reflects the reviewer's actual performance, not an assumed one.
Shortening the Revision Cycle
Reviewer response time is the variable you can't control. What you can control is how fast you turn a markup around and how much you give the reviewer to comment on. Aim to resubmit within five business days. Every day a markup sits in your own queue is a day added to the program.
Practical levers that shorten the cycle:
- Answer every comment in writing on the response sheet. Reviewers who can see their comments addressed are less likely to reopen closed items.
- Batch related markups into one resubmission. Sending three partial resubmissions creates three queue entries and three response windows.
- Flag deviations openly. A deviation register that states where the drawing departs from the specification saves a round that would otherwise be spent discovering it.
How to Shorten Turnaround Without Cutting Corners
You can compress glazing shop drawing turnaround without sacrificing accuracy, but only by front-loading the work. Speed comes from fewer revision cycles, not faster drafting.
The levers that actually work:
- Submit a complete package the first time. Fewer gaps mean fewer review rounds.
- Pre-agree the drawing standard with the reviewer. A five-minute call on sheet format and detail level saves a rejection.
- Use a specialist documentation partner. Familiarity with Alspec, Capral and Darley systems removes the learning curve on every package.
That last point matters more than most teams expect. A fabricator drafting an unfamiliar system spends days on details a specialist already knows. At BluePrint Facade, we build every package around the specific product system and the reviewer's expectations.
Frequently Asked Questions
How long do glazing shop drawings take to prepare?
Preparation time depends on package size and complexity. A small standard window wall package with a complete window schedule can be drafted in roughly one to two weeks. A larger curtain wall or curved window package with engineering input typically runs three to six weeks before the first submission. These figures assume design documents are complete and the window schedule is coordinated. Missing dimensions, unresolved design intent or late product selections push drafting back before a single line is drawn, so confirm inputs before booking a program date.
What factors affect glazing shop drawing turnaround times?
The main factors are package size, system complexity, and the completeness of design documents. Curved window walls, structural glazing and bespoke framing need more detailing and engineering sign-off than standard window walls. Approval speed matters just as much: a reviewer who returns marked-up drawings within five working days keeps a project moving, while a two-week review cycle per revision quickly consumes the program. Late decisions on glazing thickness, finishes or hardware also restart parts of the drawing package, so locking selections early is the single biggest lever.
How can project teams reduce shop drawing revisions?
Most revisions trace back to inputs, not drafting errors. Run a window schedule coordination check before submission so every opening, dimension and hardware set matches the elevations and specifications. Confirm design intent on interfaces, such as how glazing meets cladding and structure, in writing. Submit a complete package with elevations, section cuts, opening schedules and glazing specifications rather than partial sets. Finally, agree a review cycle with the contractor up front and consolidate reviewer comments into one marked-up set, so revision management stays to one or two rounds instead of four.
How do approval delays affect glazing fabrication and installation?
Fabrication cannot start until drawings are approved, so every day lost in review moves the production slot and the installation sequence. Aluminium systems are cut and assembled to approved dimensions, and glass is ordered to approved glazing thickness and sizes. A delayed approval therefore pushes the whole chain, risking out-of-sequence work on site and premium rates for compressed fabrication. Building a realistic approval timeline into the project schedule, with contingency for at least one revision cycle, protects both on-time completion and cost control.
Façade programs rarely fail on the glass. They fail on documentation sitting in a queue while the site waits. If your next package needs drawings that clear review the first time, BluePrint Facade can help. We produce façade and glazing shop drawings for window wall, curtain wall and curved window systems, with technical documentation built around the product systems you specify. Submit your project details and we'll confirm a realistic turnaround for your package.
