Turnkey Electrical
Complete Building Electrification
End-to-end electrical contracting for entire buildings — from load calculation and panel design through to final testing and commissioning. We take a building from bare structure to a fully energised, code-compliant electrical system under a single contract.
GST-compliant, warranty-backed turnkey delivery
How we deliver your complete building electrification
A clear, four-stage workflow — from the first site survey to a tested, documented handover — so you always know what happens next.
- 1
Site Survey & Load Calculation
We assess the building layout, connected load and future expansion to correctly size cables, panels and the incoming supply.
- 2
SLD Design & BoQ
Single-line diagrams, panel schedules and a detailed bill of quantities are prepared and approved before any procurement begins.
- 3
Wiring & Panel Installation
Concealed conduit wiring, cable trays, the main LT panel and sub-DBs are installed floor by floor using tested, branded materials.
- 4
Earthing, Testing & Handover
Earthing and lightning protection are laid, every circuit is meggered and load-tested, then commissioned with documentation and warranty.
