Check audio-visual system specifications against drawings

An audio-visual specification’s excluded scope of work can leave floor boxes, cutting and patching, or a rack’s grounding path to another trade without anyone confirming those trades actually picked it up. Review the AV package against the disciplines it depends on before treating the equipment list as complete.

Trace each AV-equipped room from its system description into the equipment list, then compare the excluded scope of work against the electrical and structural drawings, and confirm cybersecurity coordination and grounding before treating the AV package as coordinated.

Assemble the review package

Gather the AV drawings and equipment list, the room-by-room system description narrative, electrical plans for AV device power and floor boxes, structural backing details for wall- or ceiling-mounted equipment, and the issued audio-visual systems specification. This guide specification is intentionally general; review whether the project team edited the system description and equipment list for the actual rooms shown, rather than leaving generic placeholder language in the issued set.

WBDG publishes UFGS 27 41 00: Audio-Visual Systems as a public guide-specification reference (accessed September 26, 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.

Eight specification-to-drawing checksSwipe or scroll sideways to read all columns.
CheckSources to compareQuestion to resolve
Excluded scope of workSpecified excluded scope (cutting/patching, painting, floor boxes) + electrical and general-construction drawingsWhere the AV specification excludes floor boxes, cutting and patching, or finishes, do the electrical or architectural drawings actually assign that work to another section rather than leaving it unassigned?
Room-by-room system descriptionAV drawings + specified system description narrative for each room typeDoes every AV-tagged room have its own edited system description and equipment list, rather than relying on the specification’s generic conference-room example left unedited?
Independent system designer triggerProject complexity + specified ANSI/INFOCOMM 2M and ANSI/BICSI 001 design requirementWhere the project needs project-specific AV design services, was that design actually produced by a qualified system designer with the specified CTS-D certification, rather than the unedited guide-specification language standing in for a design?
Cybersecurity coordinationAV network requirements + specified coordination with Section 25 05 11 Cybersecurity for Facility-Related Control SystemsDoes the issued document set actually include a cybersecurity coordination reference for the AV network, rather than leaving that coordination point unaddressed?
Grounding and shieldingAV rack locations + specified rack grounding stud/bus bar and Division 26 bonding requirementDo the electrical drawings show the grounding electrode and bonding path the AV rack’s grounding stud and bonding jumper depend on at each rack location?
Mounting, rigging, and seismic restraintAV device locations + specified mounting and seismic restraint requirementDo the structural or architectural drawings show backing and any required seismic bracing at each wall-mounted display or ceiling-hung device location shown on the AV drawings?
Personnel certification requirementsSpecified Project Manager and Lead Installer certification listWere the specified personnel certifications (CTS, CTS-I, CTS-D, RCDD, RTPM, PMP) actually edited to the certifications relevant to this project’s system, rather than left as the full unedited list?
Warranty and live-support timingSpecified warranty period and live-support technician hours + project commissioning scheduleWhere live on-site support is specified around a first scheduled use date, does that date actually align with the project’s commissioning and occupancy schedule?

Worked example: a recessed outlet without its power source

Illustrative example: the specification’s conference room description calls for a wall-mounted display with an in-wall storage box recessing a surge-protected power outlet, and the AV drawings show this arrangement in a training room. The electrical drawings do not show a dedicated receptacle at the same recessed-box location, so the AV package assumes a power source the electrical package has not actually provided.

Confirm the recessed box location against the electrical drawings, add the missing receptacle if it was not carried through, and recheck the same box location for low-voltage AV cabling pathway coordination before closing the item.

Avoid a false conflict

This specification is written as a general template; a room-specific requirement not edited into the system description or equipment list can be missed even though the general AV language is present in the issued set. Do not assume a generic paragraph was updated for the actual room without checking the drawings.

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.

Questions, answered

FAQs

What should an audio-visual system document review compare?

Compare the excluded scope of work against other trades, the room-by-room system description, the independent-designer trigger, cybersecurity coordination, grounding and shielding, mounting and seismic restraint, personnel certification requirements, and warranty and live-support timing.

Does this checklist confirm the AV system meets its acoustic or video performance intent?

No. It is a document-consistency review confirming the drawings and specification describe a matching, edited system design for each room. Actual performance verification and acceptance testing remain with the responsible AV designer and commissioning agent.

Why does the excluded scope of work matter for an AV review?

The specification deliberately excludes items such as floor boxes, cutting and patching, and finishes so another trade can pick them up; if the electrical or architectural drawings do not actually assign that excluded work, it can go unbuilt.
