SDESmith Design Engineering

Sector

Banking and financial services

MEP design for branch networks and financial services offices, with resilience, security integration and out-of-hours delivery.

OVERVIEW

Banking premises combine a public-facing retail environment with a secure operational one, and the services have to serve both without compromising either.

Branch work is typically a rolling programme rather than a single project, which puts a premium on standard details that survive being applied to buildings of very different age and construction.

DESIGN

What drives the design

Resilience is specified, not assumed

Continuity requirements for tills, ATMs, communications and security systems are usually defined by the client's operational standard. The services design has to deliver the defined level rather than a general impression of robustness.

Security integration

Intruder alarm, access control, CCTV and the electrical infrastructure that serves them need coordinating with the general installation, including containment segregation and supply resilience.

Work happens around trading

Branch refurbishment is generally out of hours or in short closures, which shapes isolation, temporary supply and commissioning strategy as much as the design itself.

REGULATION

Statutory and guidance documents
