How we work

Organising ELV general contracting

In a commercial complex, rework costs more than in almost any other discipline — once cabling is buried, going back means opening walls.

General contracting starts with drawings

Rework in an intelligent building costs more than in other disciplines: once cables are closed in by the civil works, going back means breaking open walls and ceilings. In commercial complexes, fit-out and intelligent systems often run in parallel, so the point schedule and wiring diagrams have to be settled early and coordinated.

Interface management when several subsystems overlap

When security monitoring, structured cabling, background music, building automation and public-area lighting are all on site at once, the problems that surface are about who goes first and who leaves room for whom. We complete the interface demarcation before construction starts.

The boundary of building automation has to be written down

The most common failure in building automation is wanting to manage everything. At project outset we fix the interface boundary with the client in writing: we manage public plant and do not intrude on process control, with communications taking priority where there is a conflict.
