Structured cabling in London.

UK projects commonly reference the BS EN 50173 series for generic cabling within premises and the BS EN 50174 series for installation practice. Alongside them sits BS 6701, the British Standard for installing, operating and maintaining telecommunications equipment and cabling, which complements BS EN 50174. Specifications for London fit-outs may name one or more of these, sometimes next to TIA or ISO references from an overseas head office. We work to the standard in your design and record results per link, so a building surveyor, an auditor or the next contractor can check exactly what was installed and how it performed.

The building itself sets most of the constraints. In towers, risers and ceiling voids are shared between tenants and controlled by the landlord, so access is booked, often under a permit to work, and noisy work may be pushed to evenings or weekends. In older central buildings routes are narrower, and the dutyholder must tell contractors where any asbestos is before ceilings or walls are opened. Where a building is listed, visible containment or new openings can need consent. Walking the route with the building manager before quoting is the surest way to find these limits early and keep them out of the change budget.

London's IT estate is spread across very different kinds of building. Glass towers in the City and at Canary Wharf, the business district built on the former West India Docks on the Isle of Dogs, share the map with older central offices where listed status can limit alterations, as well as hospitals, schools and retail units across the outer boroughs. Most of these buildings are managed by someone other than the tenant, so a building manager, a booked goods lift and a set of contractor rules usually stand between the engineer and the work.

Data centre space gathers in a few areas rather than one. The Docklands in east London has long been densely built up with facilities, west London boroughs along the M4 corridor have drawn operators with their fibre routes, and Slough in Berkshire, just west of London, hosts a large cluster of data centres. The UK runs on Greenwich Mean Time in winter and British Summer Time in summer, which gives teams in the Americas and continental Europe a usable overlap with the London day. Deploris coordinates vetted local engineers from its network for companies run from elsewhere, with availability confirmed when the work is scoped.
