How to Create an Audio BOQ for an AV Project (Automatically)

An audio BOQ — bill of quantities — is the itemized list of every speaker, amplifier, cable run and accessory a project needs, priced and organized by room or zone, that turns a system design into something a client can approve and an installer can order against. Building one by hand from a floor plan is slow and error-prone: count speakers per room, cross-reference SKUs, tally amplifier channels, and hope nothing was missed when the design changed on the fourth revision. XSCACE's Floorplan Sound Simulation tool generates the audio BOQ automatically as a byproduct of the actual acoustic design — because that's what a BOQ is supposed to represent in the first place.

What Belongs in an Audio BOQ

  • Speaker model and quantity, broken down per room or zone — not just a project total
  • Amplifier channel count required to drive every zone, matched to real power specs
  • Subwoofer count and placement, since bass coverage is rarely one-per-room
  • Accessories — brackets, grilles, finish options — tied to the exact SKU, not a generic line item

Why Manual BOQs Break

A BOQ built in a spreadsheet is disconnected from the design the moment it's typed. Move a speaker, add a zone, or swap a model for budget reasons, and the spreadsheet doesn't know — someone has to remember to update it, on every revision, across every room. Worse, a manually-built BOQ usually isn't grounded in an actual coverage prediction: quantities come from rules of thumb ("one speaker per 15m²") rather than a simulation that accounts for room modes, reflections and real dispersion. The list can be internally consistent and still be wrong for the room.

From Floor Plan to Bill of Quantities, Automatically

Trace the room outline on an uploaded floor plan, set the real-world scale, and drag speakers onto it from the actual XSCACE catalogue — each one carrying its real sensitivity, power handling and dispersion data. As the coverage heat map updates live, the tool is simultaneously counting exactly what's been placed, zone by zone. There's no separate step where someone transcribes the design into a bill of quantities — the BOQ is a direct export of what's actually on the plan, so a design revision and a BOQ revision are the same action.

One Project, Every Zone, One Set of Totals

A real project is rarely one room. Projects are structured Floors → Zones, so a whole villa, apartment or commercial fit-out lives in a single file — every floor gets its own plan and scale, every zone gets its own SPL map and speaker schedule. On export, the BOQ doesn't stop at one room's totals: it rolls every zone on every floor into one set of project-wide numbers, the same document a client signs off on for the whole job, not a stack of per-room spreadsheets stapled together.

What the Export Actually Contains

  • A branded Excel quotation spreadsheet with live totals, ready to send to a client
  • An indexed PDF report with a cover page and clickable table of contents
  • One page per zone with its SPL map, technical details and signal-flow diagram
  • 3D views and a phase-based commissioning checklist for the install crew

  • BOQ generated directly from the placed speakers — not a separate manual step
  • Multi-floor, multi-zone projects roll into one set of project-wide totals
  • Exports: Excel quotation, indexed PDF report, 3D views, commissioning checklist

Frequently Asked Questions
What is an audio BOQ?

An audio BOQ (bill of quantities) is the itemized list of every speaker, amplifier, subwoofer and accessory an AV project needs, quantified and organized by room or zone — the document a client approves and an installer orders against.

How do I create an audio BOQ automatically?

Design the system on a real floor plan — trace the rooms, place actual catalogue speakers, set the listening position — and a tool like XSCACE's Floorplan Sound Simulation tracks every product and quantity per zone as you work, then rolls the whole project into a BOQ on export. No manual line-item entry.

Is the BOQ generator free?

Yes. XSCACE's Floorplan Sound Simulation tool is free, browser-based, and needs no account — the BOQ, Excel quotation and PDF report are all included.

Does the BOQ reflect real product specs or rough estimates?

Real specs. Every speaker placed in the simulation pulls its actual sensitivity, power handling and dispersion from the same product database that powers the XSCACE website, so the BOQ and the acoustic prediction are generated from the same real numbers, not a separate guess.

Can I export the BOQ to Excel?

Yes — a branded quotation spreadsheet with live totals, alongside a client-ready indexed PDF report.

Does it handle multi-room or whole-house projects?

Yes. Projects are structured Floors → Zones, so a whole villa or commercial fit-out is one project, and the BOQ rolls every zone on every floor into one set of project-wide totals — not a separate document per room.

Do I need to be an acoustics expert to generate an accurate BOQ?

No. The tool handles the acoustic modelling — coverage, room modes, reflections — in the background while you place speakers, so the BOQ it produces is grounded in a real simulation even if you never look at the SPL map directly.
