Start with the section’s two drawing notes: confirm that the finish schedule, partition types, and reflected ceiling plans show the location and extent of each type of veneer plaster and the control joints, and that the partition types give the thickness of the gypsum base and backing board for every application. Then check that the one- or two-coat choice is made the same way in both places the issued Section 09 26 00 asks for it, that the framing, head-of-wall, door jamb, and blocking details suit a thin, hard finish that cracks with its substrate, that rated walls and shaftwalls cite designs that include the veneer plaster, and that the schedule lets the building be closed in and conditioned before plastering.
Assemble the review package
Gather the finish schedule and room finish legend, the partition type sheet with board types, layers, and framing, the floor plans with partition tags and rated walls, the reflected ceiling plans with plaster ceilings, soffits, and access panels, the interior elevations and casework drawings with wall-hung cabinets, counters, monitors, and grab bars, the door schedule with frame types and any wide, paired, or shielded doors, the head-of-wall and partition-to-structure details, the life safety plan with rated assembly design numbers, the shaft and stair enclosure details, any masonry or concrete walls scheduled for plaster, the mechanical schedule for temporary heat and ventilation, and the issued Section 09 26 00 with Sections 06 10 00, 09 22 00, 09 29 00, 09 90 00, and 01 33 00 where they are issued. Follow one plastered corridor wall from its framing and base through its joints, openings, and finish coat before assuming the others match.
WBDG publishes UFGS 09 26 00: Veneer Plaster as a public guide-specification reference (accessed November 11, 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 |
|---|---|---|
| Extent, types, and finish schedule | Opening drawing note (location and extent of each type of veneer plaster and of control joints) + General Requirements (extent and location as shown) + Finish Coat note (smooth-troweled by default; texture pattern to be named if wanted) + Venetian plaster note (mockups, applicator experience, environmental controls, protection) + finish schedule, room finish legend, partition types, and reflected ceiling plans | Does every room, wall, and ceiling scheduled for veneer plaster appear on the finish schedule with a type the section can identify, are the plastered ceilings and soffits on the reflected ceiling plans as well as the walls, is a texture named where the schedule shows one, since the section assumes a smooth finish, and where Venetian or decorative plaster is scheduled, has the specifier added the mockup, applicator, and protection requirements the note asks for, since the section as printed has none? |
| One-coat or two-coat, and the second bracket | General Requirements note and bracket (one-coat or two-coat) + Application of Gypsum Veneer Plaster bracket (one-component or two-component; minimum thickness for each) + Base Coat note (delete base coat for one-component) + Gypsum Veneer Plaster (finish coat strength bracket) + Steel Framing note (abuse) + finish schedule and abuse zones | Has the specifier made the same choice in both brackets, since General Requirements speaks of a one- or two-coat system and the Application article and Base Coat note of a one- or two-component system, is the Base Coat article deleted only where one coat is kept, and does the choice follow the note, which points to two coats where physical abuse matters, for the corridors and high-traffic rooms the drawings mark for impact? |
| Gypsum base, backing board, thickness, and substrates | Materials note (drawings show the thickness of base and backing board for all applications) + Gypsum Backing Board brackets (regular, foil-backed, water-resistant, mold-resistant, abuse-resistant, glass-mat, Type X; square edges for the first ply) + Gypsum Base (non-combustible test; abuse-resistant option) + Application of Gypsum Base (wallboard allowed as base ply; adhesive except where the rating prohibits it) + Application note (masonry and concrete substrates) + opening description note (not in showers or very humid rooms) + partition types | Does each partition type give the thickness and type of base and backing board, as the note requires, are moisture-resistant backing boards kept only for rooms the opening note does not rule out for veneer plaster, does the gypsum base product data show the non-combustibility test the article names, and where masonry or concrete walls are scheduled for plaster, has the specifier added the conditioning and bonding treatment the note says those substrates need? |
| Framing, deflection, and isolation from the structure | General Requirements (metal framing specified in this section; wood framing under Section 06 10 00 as an option) + Steel Framing note (isolate partitions from the structural frame; strengthen for heavy wall-hung loads) and article (stud spacing; applied loads) + Partition Framing System (transverse load and deflection; stud thickness by facing; metric load printed in an undefined unit) + Special Framing + Section 09 22 00 where issued + head-of-wall and partition-to-structure details | Which section governs framing behind veneer plaster where Section 09 22 00 is also issued, since this section says the framing is specified herein, do the head-of-wall and partition-to-column details isolate the partitions from the structural frame, as the note advises, has the specifier corrected the metric transverse load in Partition Framing System, which is given in a unit that does not exist, and where wood framing is allowed, do the details and fasteners match it? |
| Door jambs, openings, blocking, and wall-hung items | Wall Openings (anchorage of frames; doubled jamb studs; heavy-door bracket; inch-pound jamb stud thickness that does not express its metric value) + Blocking (blocking for mounted equipment; nothing anchored to the plaster alone) + Ceiling Openings (support members for access panels, lights, and air devices; “minimum support specified herein”) + door schedule, interior elevations, casework and equipment drawings, and reflected ceiling plans | Is the jamb stud thickness in Wall Openings corrected so the metric and inch-pound values describe the same stud, and is the heavy-door bracket filled in for the wide, paired, and shielded doors on the door schedule, are blocking locations shown or scheduled for every cabinet, counter, monitor, rail, and grab bar on the elevations, and since Ceiling Openings refers to minimum support for furring that no article of this section specifies, which section sets the support for plaster ceilings and their openings? |
| Control joints, beads, and curved surfaces | Control Joints note (locations on the drawings; spacing limits for walls, restrained ceilings, and ceilings with perimeter relief; joints at the wings of L, U, and T ceilings) and article (one-piece products for veneer plaster) + Corner Bead, Casing Bead, and Control Joints (coated steel, or vinyl or anodized aluminum options) + Curved Surfaces (bending radii; bonding agent where base is dampened) + reflected ceiling plans, interior elevations, and curved wall details | Are the control joints drawn on the elevations and ceiling plans, as the note asks, at spacings within its limits and at the wings of shaped ceilings, do they align with joints in the framing and the structure and with door frames, is one bead and joint material chosen where the bracket offers several, and do the curved walls and soffits on the plans have radii the gypsum base can be bent to? |
| Rated assemblies, shaftwalls, and vapor retarders | Fire Resistive Construction note (details must follow tested designs; veneer plaster added to a rated gypsum board design) and bracket (design numbers indicated, UL or FM listings) + Gypsum Backing Board and Gypsum Base (Type X options) + Shaftwall Framing System and Cavity Shaftwall System (tested designs; manufacturer’s instructions) + Application of Gypsum Base (no adhesive where the rating prohibits it) + Vapor Retarder materials and installation articles + life safety plan, rated partition types, shaft details, and exterior wall sections | Does every rated partition and shaftwall that receives veneer plaster cite a tested design number on the partition types or life safety plan, does that design include the base, backing board, and framing the section specifies, is the Fire Resistive Construction bracket kept where any rated wall is plastered, and where a vapor retarder is kept, do the exterior wall sections show which face it goes on and which of the three options the section allows is intended? |
| Close-in, temporary conditions, sequence, and submittals | Scheduling (weathertight; heating, ventilating, and air-conditioning operating, or an approved plan to maintain conditions; plaster before finish flooring and acoustical ceilings) + Environmental Requirements note and article (temperature range before, during, and after plastering; shielded air devices; ventilation; window openings; screening) + Delivery and Storage + Submittals (product data for base and plaster; recycled content; installation instructions) + Materials (powder-driven fasteners only with written approval; miscellaneous items approved before use) + construction schedule and mechanical startup | Does the construction schedule close in and condition the plastered areas before plastering and keep them conditioned for the cure the section requires, are temporary heat and ventilation planned where the permanent system will not run in time, and since the approved environmental plan, the written approval of powder-driven fasteners, and the approval of miscellaneous items have no submittal item, has the specifier added them to the list or to Section 01 33 00? |
Worked example: a clinic corridor with two system brackets, no control joints, and a jamb stud that does not add up
Illustrative example: a clinic renovation schedules veneer plaster on the main corridor walls and the ceiling of the waiting room, with stretcher traffic along the corridor and wall-mounted monitors and handrails on both sides. The finish schedule shows the corridor as abuse-resistant, but the partition types give no base or backing board thickness, the interior elevations show no control joints along a long run of corridor wall, and the reflected ceiling plan shows the L-shaped waiting room ceiling with none at its wing. The issued Section 09 26 00 keeps two coats in General Requirements but keeps the one-component bracket in the Application article, keeps the metric and inch-pound jamb stud values as printed, keeps Section 09 22 00 for framing alongside its own framing articles, and keeps the Fire Resistive Construction bracket though the rated corridor walls on the life safety plan cite gypsum board designs with no plaster.
Ask the architect to add base and backing board thicknesses to the partition types, to draw the control joints on the corridor elevations and at the wing of the waiting room ceiling, to show blocking for the monitors and handrails, and to confirm that the rated corridor designs allow the added plaster. Ask the specifier to set the Application bracket to the two-component system so it agrees with General Requirements, to correct the jamb stud and transverse load values, to name one section for the framing behind the plaster, and to add submittal items for the environmental plan and any powder-driven fasteners, and confirm with the contractor that temporary heat and ventilation will hold the conditions the section sets before, during, and after plastering.
Avoid a false conflict
Section 09 26 00 covers veneer plaster over special gypsum base on steel framing, with its own framing articles and a bracketed option for wood framing. Gypsum board without plaster follows Section 09 29 00 and the gypsum board guide, framing and furring issued separately follow Section 09 22 00 and the non-structural metal framing guide, conventional gypsum plaster on lath follows Sections 09 23 00 and 09 22 36, exterior cement plaster follows Section 09 24 23 and the cement stucco guide, and painting follows Section 09 90 00, so check those before calling a requirement missing. Some of the section’s own wording needs resolving before it is compared with the drawings: General Requirements and the Application article choose the system with different terms, coats and components; the jamb stud thickness in Wall Openings and the transverse load in Partition Framing System are misprinted in one of their units; Ceiling Openings refers to support for furring that no article specifies; and the environmental plan, powder-driven fasteners, and miscellaneous items need approvals that have no submittal item. Ask the specifier which wording the project intends before treating a difference as a design conflict.
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.
