Occupied MEP renovation: isolate one circuit, do not black out the building

A core field strength — not a side job. Live plants, hospitals receiving patients, bank branches at the counter, civic offices and live security systems: survey the real board, work off-peak, hand back a true as-built.

On contract

  • Power, MSB/DB/ATS, UPS, lighting.
  • HVAC on a building that must stay cool — one AHU at a time.
  • ELV: migrate CCTV/access cluster by cluster while the old system records.
  • Civil works locked to containment and ceilings.

Order we keep

  1. Open the live board before we price.
  2. Outage permit: circuit, hours, owner’s witness.
  3. Parallel feeders when possible; night shift when the contract says so.
  4. No whole-MSB, whole-chiller or whole-CCTV outage without a written temporary supply.
  5. As-built on the door, passwords to the named owner contact.
