Start with the opening notes of the issued Section 08 51 23: confirm that the project location is not one where the notes rule out steel windows, then check that the window schedule, elevations, and details give each window’s size, type, ventilator swing, anchorage, mullions, special glass, and screens, and that only the window type articles drawn are kept. Then check that fire-rated windows are located and labeled, that security windows are identified, that the thermal, windborne debris, and antiterrorism blanks are filled in from the energy, wind, and security criteria, and that operators for high or grouped windows are drawn, with motorized operators on the electrical drawings.
Assemble the review package
Gather the window schedule and window type elevations, the building elevations, the head, jamb, sill, and mullion details, the wall sections showing sub-frames, stools, casings, and the masonry or concrete openings, the code analysis and life safety plans marking fire-rated walls and opening protectives, the security plans identifying storage areas that need security windows, the energy compliance documents, the structural wind criteria and windborne debris region, the antiterrorism criteria and standoff distances, the electrical drawings for motorized operators, the design analysis with the climate zone and environmental severity classification, and the issued Section 08 51 23 with Sections 08 81 00 and 09 90 00, plus Section 08 51 13 if aluminum windows are also used. Trace one operable window type from its schedule row through its details, operator, and performance values before assuming the others match.
WBDG publishes UFGS 08 51 23: Steel Windows as a public guide-specification reference (accessed November 3, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Location and corrosion limit | Opening designer note + design analysis climate zone and environmental severity classification + Section 08 51 13 | Does the design analysis place the project in a humid climate zone or a corrosive severity class where the opening note says not to use steel windows, and if so, has the architect recorded how the fire-rated or security windows that the notes say must be steel will be handled, with the other windows moved to aluminum under Section 08 51 13? |
| What the drawings must show | Opening designer note on drawings + Shop Drawing Information article + window schedule, elevations, and details | Does the set give each window’s size and type, any sub-frames, casings, or stools, the hardware, ventilator size, location, and swing, fixed sash details, the anchoring method with clip, anchor, screw, and fastener types, non-structural mullion and cover details, special glass locations, and insect screen locations, as the note lists? |
| Window types and weight classes kept | Window Types article and its designer note + Awning, Casement, Continuous, Fixed, Horizontally Pivoted, Projected, and Security Windows articles + window schedule | Is each type on the schedule matched by a kept type article with one weight class chosen where the article offers Standard Intermediate, Heavy Intermediate, or Heavy Custom, are unused type articles deleted, as the note directs, and does the unit description list the sub-frames, mullions, casings, screens, or storm units the details show? |
| Fire-rated windows | Fire Rated Windows article and its designer note + Installation article + life safety plans + code analysis + Section 08 81 00 | Are fire-rated windows located on the drawings, as the opening note asks, with the rating class for each one taken from the rated wall or opening on the life safety plans, is the bracketed NFPA 80 and NFPA 101 installation sentence kept when they are used, and is the glass in those windows coordinated with the fire-rated glazing in Section 08 81 00? |
| Security windows and forced entry | Security Windows article and its designer note + forced entry option in the Test Report Requirements article + security plans + elevations | Are security windows identified at the warehouses and storage rooms the note describes, with a finish matching any adjoining aluminum windows, is the forced entry test report kept only where those windows are used, and if detention windows are needed, has the section been modified as the note says, since detention use is not covered? |
| Thermal, wind, and debris criteria | Thermal Performance, Structural Performance, Mullion and Transom Bar Wind Load Tests, Windborne-Debris-Impact Performance, and Mullions and Transom Bars articles + energy compliance documents + structural wind criteria | Are the SHGC and U-factor blanks filled in from the energy compliance documents and coordinated with the glass in Section 08 81 00, is the mullion wind load paragraph kept or deleted as its note directs for the site’s wind, and if the windborne debris paragraph is kept, do the drawings classify which windows need basic or enhanced protection? |
| Antiterrorism and blast design | Antiterrorism Performance Requirements, Computational Design Analysis Method, Dynamic Design Analysis Method, Standard Airblast Test Method, Engineer’s Qualifications for Blast Design, Design Data Requirements, and Provisions for Glazing articles + security criteria | If the security analysis identifies an explosive threat, is one validation method kept with its load and hazard rating blanks filled in by an engineer experienced in blast design, does the structural analysis say whether blast or windborne debris governs, and if no threat applies, are the blast, forced entry, and antiterrorism paragraphs removed, as the notes direct? |
| Operators, anchors, finish, and screens | Special Operators, Pole Operators, Extension Crank Operators, Mechanical Operators, Anchors, Anchors and Fastenings, Window Finish, and Screens articles + elevations + electrical drawings + Section 09 90 00 | Are the number and location of extension crank operators shown, are mechanical operators for continuous rows or high windows drawn with their power unit, shafting, and supports, with motorized operators on the electrical drawings, does the anchor option kept match the masonry or concrete opening detailed, is a shop primed or factory finish chosen with field coats in Section 09 90 00, and is the screen type chosen? |
Worked example: a rated stair window and clerestory windows with no operators
Illustrative example: a two-story vehicle maintenance building has projected steel windows in the shop bays, a high continuous row of windows along the clerestory, and one window in a fire-rated stair enclosure wall. The window schedule gives type marks and sizes but no weight class, the issued Section 08 51 23 keeps every window type article and the full antiterrorism article with its blanks empty, the stair window is not identified as fire-rated on the schedule or elevations, and the clerestory windows show no operators on the elevations or the electrical drawings, although the Continuous Windows article keeps motorized operation.
Ask the architect to add the weight class to each schedule row, delete the unused type articles, identify the stair window as fire-rated with the class the enclosure needs, and coordinate its glass in Section 08 81 00. Ask the security engineer to confirm whether an explosive threat applies so the antiterrorism paragraphs are filled in or removed, and ask the architect and electrical engineer to show the clerestory operators, their power unit, and their circuit, or to change the article to manual operation.
Avoid a false conflict
Section 08 51 23 covers standard steel window units. Glass and glazing are specified in Section 08 81 00 and the glazing guide, field painting in Section 09 90 00 and the painting guide, and aluminum windows in Section 08 51 13 and the aluminum window guide, motorized operators belong on the electrical drawings and in Division 26, and the section does not cover detention windows, so check those before calling a requirement missing. Its notes say that windows needing a UL fire rating and security windows must be steel, and also that steel windows should not be used in humid or corrosive locations, so the choice between the two window sections is a design decision for the architect. The current guide section cites the SWI Steel Window Specifications, AAMA/WDMA/CSA 101/I.S.2/A440, NFPA 80, NFPA 101, ASTM E1996, ASTM F2248, and UFC 4-010-01; confirm the editions your project invokes with the architect, the security engineer, and the authority having jurisdiction.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
Where Groundbook fits
Groundbook’s drawing and specification review helps investigate potential disagreements in the documents you supply. Include the relevant specification sections and drawing references, then verify the cited evidence with the responsible reviewers before acting on a finding.
