Architect-Ready CAD Checklist for AV Equipment Concealment

Architect-ready deliverables for concealed AV

Concealing AV without compromising performance or serviceability starts in CAD, not the field. This checklist is for architects, tech-savvy builders, and specification writers who need build-ready AV drawings.

• Show device locations on plan views and reflected ceiling plans so sightlines and mount coordinates are clear.
• Provide elevations and cabinet details that guarantee equipment depth, ventilation, and long-term service access.
• Include equipment schedules and bills of materials that specify models, power needs, and connectivity.
• Supply signal flow and wiring diagrams that trace every path back to the head end or equipment room.
• Deliver CAD and BIM files at LOD 300 or higher for clash detection and coordination.

Coordinate early in Schematic Design, Design Development, and Construction Documents to avoid costly field changes. We focus on pathway routing, millwork integration, sightlines, and systems verification so technology stays hidden yet serviceable. AVIXA lists the essential deliverables above. For a phase-by-phase checklist, see our pre-construction AV deliverables architects actually need.

Which CAD files, LOD, and BIM families to request for concealment coordination

Want AV that disappears but stays serviceable in the finished space?

Ask for DWG for 2D plans, RVT plus parametric RFA families for BIM, and exportable PDFs for team review. DWG remains the industry standard for 2D construction drawings according to Autodesk.

Provide Revit project files and custom .rfa families with accurate geometry and metadata so components behave in BIM tools. RVT and RFA files are the expected formats for BIM projects, per Autodesk Revit guidance.

Match Level of Development to the design phase so concealment is coordinated early and avoids field changes. Use LOD 200 at Schematic Design, LOD 300 for Design Development and Construction Documents, and LOD 350–400 for complex fabrication and millwork. These LOD definitions follow industry practice from BIMForum.

When you supply families, include dimensions, power and heat-dissipation metadata, and service-access notes. Also add visibility parameters and mounting clearances so architects can check sightlines, ventilation, and access in elevations and RCPs.

• Provide floor plans and reflected ceiling plans showing exact device locations to verify sightlines and mount coordinates.
• Deliver elevations and millwork details that document equipment depth, ventilation, and access panels for serviceability.
• Include equipment schedules and bills of materials that list model, dimensions, power, and connectivity for trade coordination.
• Supply signal-flow and wiring diagrams that trace every path back to the head end and link into the master drawings.
• Export Revit families (.rfa) with metadata and a DWG export plus a printable PDF set for bidding and review.

Deliver this package at LOD 300 for most construction documents and up the detail level for custom concealment. That approach keeps the design clean and prevents costly rework on site.

Construction-ready callouts, cutouts, and blocking architects can drop into CAD

Want drawings you can paste straight into construction documents so AV stays invisible and serviceable? Start with precise plan and reflected ceiling coordinates, not loose notes.

Show exact X/Y offsets from finished walls and gridlines for speakers, displays, cameras, and projectors. Call out relationships to lighting, HVAC diffusers, and sprinklers so trades avoid conflicts. Reflected ceiling plans are critical for this coordination, per Autodesk on RCPs.

• Plan views with mount coordinates and furniture sightlines so screen centers and speaker arrays align with seating.
• Reflected ceiling plans that locate ceiling speakers, projectors, and mounts relative to lighting and sprinklers.
• Elevations and millwork details that specify exact cutouts, tolerances, access panels, and ventilation paths.
• Soffit, attic, and wall sections showing cavity depths, mounting boxes, and required clearances for recessed devices.
• Equipment-rack elevations, schedules, and signal-flow diagrams linking power, data, and low-voltage pathways.

Framing, blocking, and mounting callouts

Specify structural blocking for displays and heavy mounts in your millwork notes. A common integrator standard is a 4 by 4 foot plywood panel centered at the mount for large displays.

Show rigid mounting for ceiling projectors using a 1.5 inch NPT pipe anchored to structure. Detail the anchor point and the service clearance for lamp or module replacement.

Call out conduit and raceway sizes in plan and section details. Specify 1 to 1.25 inch conduit for AV runs and a 12 inch separation between power and data to limit interference.

Ventilation, clearances, and service positions

Document thermal management in millwork notes rather than leaving it to the field. Specify a target internal operating temperature below about 85 degrees Fahrenheit and require airflow calculations based on total BTU load, per APC guidance.

Show intake and exhaust locations, use perforated panels or louvered doors, and call for blanking panels in rack elevations. Provide 2 to 3 feet of clear working space in front of and behind racks for safe service access.

For motorized screens and lifts, draw both the "store" and "service" positions in elevations and sections. Label each position, show the service-access envelope, and note required clearance for removal and maintenance.

When you hand off CAD, embed equipment model dimensions, power and heat metadata, and service-access notes in families. For practical guidance on wiring and equipment-room coordination, see our detailed guide at How to plan low-voltage wiring for custom homes.

Conduit, Separation, and Spare Capacity to Show in CAD

Worried hidden wiring will block a duct or a beam during construction? Make CAD the place you solve those problems, not the field.

Start by calling out conduit sizes, sleeve locations, and plenum status on plan and section views. Show whether a space is plenum and which cable jacket is required so trades buy the right materials up front.

Key CAD callouts for pathways and separation

• Annotate conduit inside diameter and fill percentage so installers know pull capacity and which cable types fit.
• Mark sleeve locations through structure and coordinate them with the structural model to avoid late drilling.
• Label plenum versus non-plenum routing and require CMP or metal conduit where air handles return, so code is clear.
• Note minimum separation from power for unshielded data cables, and where shielded cables or metallic barriers are required.
• Over-provision conduit and pathways by roughly 30 to 50 percent so future adds avoid invasive retrofits.
• Show pull points and limit total bend to avoid more than 360 degrees of bend between pulls for safe installation.

Labeling, backbone, and spare runs

Label every cable at both ends with machine-printed tags that show source, destination, port, and signal type. Document the color or symbol legend in the drawing notes so crews interpret labels consistently.

Specify Cat6A as the baseline for horizontal runs supporting 10 Gigabit Ethernet up to 100 meters. Call out fiber for longer or high-capacity backbone links so the head-end stays scalable.

Pull spare speaker and data runs to key zones during rough-in. Show dedicated empty conduit runs in CAD so future devices can be added without opening finished walls.

Firestop, concealed mechanisms, and outdoor transitions

Call out rated firestop systems for every penetration and reference the firestop detail or catalog number. That prevents field delays and keeps the as-built CAD tied to compliant firestopping.

Represent motorized screens, lifts, and retractable speakers with plan, RCP, and elevation positions for "store", "show", and "service". Include electrical and low-voltage connection points and the service-access envelope so trades know clearances.

For exterior transitions, show weatherproof junctions, continuous conduit to the outdoors, and where outdoor-rated cables begin. That level of detail keeps installers from guessing and avoids leaks or premature cable failure.

For separation rules and cable ratings, see guidance from TIA, for labeling and concealment conventions consult AVIXA, and for firestop requirements reference the NFPA/NEC guidance.

Putting the checklist into your project handoffs

Want concealed AV that stays serviceable? Plan AV as infrastructure from schematic design onward. Set LOD targets, include device locations, millwork cutouts, conduit and spare runs, and embed power and heat metadata in families. Use 3D BIM and clash detection to catch conflicts before construction.
