The core of our practice

Pro Audio-Visual System Design

Technical design documentation for audio-visual systems, from the first concept drawing to the as-built set an installer works from.

Audio-visual wiring and pin-out detail drawing showing connector terminations

Line Draw CAD Lab prepares detailed technical design documentation for audio-visual systems across commercial, hospitality, corporate and public-sector projects. The work covers the full progression from concept to as-built documentation, including the architectural layouts that carry the audio-visual design.

We prepare documentation for use on site rather than for record purposes alone. Cabling pathways on a floor plan align with the schematic wiring terminations and the rack arrangement, and every termination traces to a schedule. The aim is a package an installer can build from without returning for clarification. Every set is reviewed against the required standards before it leaves the practice, as our three-stage process sets out.

What the service covers

- Pin-out detail for audio-visual and control connections
- Point-to-point cable schedules cross-referenced to rack and floor plan drawings
- Cable labels, equipment manufacturer and mounting detail
Delivery and submission documentation 4

- Tender submission packages formatted consistently across every sheet

Why outsource to us

Audio-visual as the founding discipline

Audio-visual documentation is the work the practice was established to do. Every drafter on it understands how a system is installed, not only how it is drawn.
Continuity across the project

The same drafter follows a project from schematic through to as-built, so revisions are handled by someone who already understands the system.
Documentation prepared for site teams

We prepare every sheet for the individual working on site. Resolving pathways, terminations and mounting details at the documentation stage prevents the site queries that incomplete drawings produce.
Capacity that adjusts to demand

Drafting requirements are rarely constant. Our capacity follows each client's pipeline, providing resources when a tender is secured and none when work is absent.
