Glass orders checked lite by lite against approved shop drawings, before your project manager releases them.

A glass order lists lites by mark: width, height, make-up, treatment, coating surface, spacer and quantity. Someone builds it from the approved shop drawings and field sheets, often as openings get measured, and sends it to the fabricator. Reorders for breakage and lites waiting on a dimension run through the same log.

In the test, AI reads copies of those orders, drawings and field sheets and drafts a check sheet: each lite compared with the approved drawing and the field dimension for size, make-up, tempering, safety marking, coating surface and spacer color, plus a list of reorders and lites still waiting on a dimension. Nothing is released, changed or sent. Your reviewer compares each sheet with what your project manager flagged, and with any lite that later came back wrong.

Treatment can't be undone. The Consumer Product Safety Commission's standard for architectural glazing, 16 CFR Part 1201, defines tempered glass as glass that cannot be cut, drilled, ground or polished after treatment without fracture. So a line that reaches the fabricator with the wrong dimension is fixed only by making the lite again. One fire-rated glass maker's guide spec tells the glazier to verify openings by field measurement before fabrication and to confirm those dimensions on the shop drawings. The draft compares each order size with the approved drawing and the latest field sheet, and lists any lite with no field dimension instead of assuming one.

A make-up is several fields, and the surface matters. The University of Houston's glazing section writes insulating units by overall thickness, lite thickness, outdoor and indoor lite, interspace and coating surface: second or third surface on one low-E type, second only on another, fourth surface on ceramic spandrels. Its glazing schedule has to use the drawing's own designations. New York's 2024 master spec offers twelve perimeter spacer options, from black or bronze anodized aluminum to stainless steel covered in polypropylene, some in a color the architect selects. Both sections can require roll-wave distortion parallel to the bottom edge as installed, and New York's notes say to verify the sizes can be made that way. The draft reads every field separately and marks any line where the order's designation, surface, spacer or orientation differs from the drawing.

Marks are code requirements attached to a line. Section 2403.1 of the International Building Code, in the 2021 edition Seattle adopted, has each pane carry the maker's mark for type and thickness, omitted only with approval and an affidavit from the glazing contractor. Tempered glass needs a permanent mark, acid etched, sand blasted, ceramic fired, laser etched or embossed, while tempered spandrel gets a removable paper marking. The National Glass Association's paper FB11-06 says permanent marks should sit where bite, gasket or sealant won't hide them, and a Safety Glazing Certification Council label carries its number, the standard and category, nominal thickness and a letter for certified size. Houston also wants certified insulating units marked on a spacer or on one lite. The draft notes which lites the drawing calls for safety glazing and what the order says about marking.

Safety and fire glass add their own rules. Under 16 CFR 1201, a door with any single piece over 9 square feet takes Category II, and one with none over 9 can be Category I; New York's spec simply asks for Category II wherever safety glazing is indicated. The same rule has organic-coated glass tested from one side labeled GLAZE THIS SIDE IN. New York's section 08 88 13 wants a fire-rated lite's label to show the test standard, whether it can go in doors or openings, the hose-stream result, the 450 degree temperature-rise limit and the rating in minutes. Laminates are often not symmetrical, the NGA paper notes, so a removable label says which face goes inside. None of this is legal or engineering advice; what a lite must be stays with your project manager and the design team.

What your reviewer will watch: size on field-measured lites, make-ups that changed between the approved drawing and the order, tempering and marks on lites the drawing calls for safety glazing, coating surface and spacer color, reorders that repeat the first mistake, and lites released while still waiting on a dimension. The NGA paper adds that fabricators' removable labels list size, make-up, weight, customer name and purchase order, which gives a way to trace a delivered lite back to its line.

Once your reviewer says yes, new orders get the same check for about 30 days, before anything goes to the fabricator.

Your project manager releases every order. The sheet lists what differs; deciding what to change, hold or release stays with that person.

Your reviewer keeps comparing live sheets with what your team catches. The live job's fixed price comes before signing, the next job is priced on its own, and monthly support follows.
