Project Delivery
Rough-In
The construction phase where pathways, boxes, sleeves, and cable are installed before walls close, ahead of any device or equipment installation.
Rough-in is the one irreversible phase for low-voltage work. Once drywall, ceilings, and millwork are in, adding a drop stops being cheap. Every device location, plus deliberate spares, has to be resolved on paper before this window closes.
It rewards over-provisioning. A few extra conduits, a larger sleeve, and pull strings left in place cost very little during rough-in and are the difference between a simple future upgrade and a demolition project.

- Conduit Fill
- The code limit on how much of a conduit's cross-section may be occupied by cable, set so cables can be pulled without damage and can dissipate heat.
- Division 27 / 28
- The CSI MasterFormat sections covering low-voltage work: Division 27 is communications — cabling, AV, paging — and Division 28 is electronic safety and security, including access control and surveillance.
- As-Built
- Documentation reflecting what was actually installed — final device locations, cable routes, labelling, IP addresses, and configuration — rather than what was originally drawn.
- Structured Cabling
- A standards-based cabling system built as an organised hierarchy — entrance facility, backbone, telecom rooms, horizontal runs, work area outlets — rather than point-to-point runs added as needed.
