Executive summary

Mediclinic International took over the former BAT building in Stellenbosch as its new head office and used the refurbishment to move the whole building off fluorescent lighting. We supplied 1,748 backlit LED panels selected on four criteria the client set itself: a five-year warranty, backlit construction, local manufacture, and demonstrated compliance with the required illuminance levels.

The project

What the site needed, and what we did

Taking over an existing building is different from fitting out a new one. The ceiling grid and the circuit layout are both inherited, and the refurbishment programme runs to a move-in date that does not move. The client had decided to invest in LED rather than re-lamp the existing fluorescent installation. That costs more on day one and is only defensible if the fittings are still performing a decade later.

That put the weight of the project onto specification rather than installation. With 1,748 panels going into a single building, a poor selection becomes a building-wide failure with a single point of origin.

How we solved it

The client set four selection criteria and we specified against them rather than against price. A five-year warranty, because at this volume the warranty term is the real risk transfer. Backlit construction rather than edge-lit, for more even luminance across the diffuser and better long-term uniformity as the panel ages. Local manufacture, so replacement panels years later come from the same line and match rather than arriving as a visibly different white. And demonstrated compliance with the illuminance levels the working areas required, evidenced rather than claimed.

The 600 × 600 panel that met all four went in across the refurbishment. Panels were supplied to the client's appointed electrical contractor, who installed to the refurbishment programme.

Why it worked

What made the difference

Backlit, not edge-lit

Backlit panels hold luminance more evenly across the diffuser and age more predictably. At 1,748 units, uniformity over time is the whole game.

Local manufacture as a spares strategy

A replacement panel five years on comes off the same line and matches. Imported stock changes constantly, and a mismatched panel in a ceiling grid is visible from the door.

Warranty scaled to volume

A five-year term on 1,748 fittings is a materially different risk position from the same term on fifty. The client set the bar and the specification met it.

Carried forward

What we would tell the next client

Letting the client set the selection criteria up front made this project straightforward. Four written criteria turned a specification argument into a compliance check, and there was nothing to negotiate once a fitting either met them or did not.
