Commercial Brickwork: Programme Pressure, CDM, and Specification Rigour

20 March 2026 by Michael Swan 2 min read

Commercial projects operate under tighter programmes, stricter H&S requirements, and more detailed specifications than domestic work.

The brickwork on a commercial project in Maidstone or Medway follows the same physical principles as domestic work, but the operating environment is different in almost every other respect. Programmes are compressed, specifications are architect-detailed, and the Construction (Design and Management) Regulations 2015 apply in full.

Programme and Coordination

On a multi-trade commercial site, the brickwork phase is typically on the critical path. The main contractor issues a programme (usually in MS Project or Asta Powerproject format) with start and finish dates for each trade. Slippage in brickwork delays the cladding, the windows, the internal fit-out, and ultimately the handover date. Liquidated damages on commercial contracts can run to hundreds or thousands of pounds per day. We manage this by agreeing realistic durations upfront, maintaining clear daily communication with the site manager, and flagging any potential delay the moment we see it.

CDM Regulations

On commercial sites, the CDM 2015 regulations require a Construction Phase Plan, risk assessments, and method statements for every significant activity. For brickwork, this includes safe working at height (scaffold specification, edge protection), manual handling of heavy materials, dust control during cutting (water suppression and RPE), and hot works if any cutting or welding is involved.

Specification Detail

Commercial brickwork is typically specified by the architect using NBS Specification clauses. The specification will name the exact brick (manufacturer, product name, colour reference), mortar designation, joint profile, and sometimes the bond pattern. Deviations from the specification require an architect is instruction (AI), not a site decision.

Frequently Asked Questions

For gates over 50 kg per leaf, we build piers at 327.5 x 327.5mm minimum. For very heavy automated gates, one-and-a-half-brick or two-brick piers may be needed.
Built in. Hinges (pintles) set into the mortar joints as the pier rises are vastly stronger than surface-fixed alternatives because the load is distributed across multiple courses.
Yes. Gate piers carry concentrated and dynamic loading from the gates, so they need deeper and wider foundations than the connecting wall panels. On Kent clay, 600 x 600mm at 900mm to 1,200mm depth is typical.
If the piers are strong enough to take the additional stress of a motor and the repeated opening/closing cycle. A structural assessment of the existing piers is recommended before fitting automation.
A flat stone cap (50 to 75mm thick) with a 40mm overhang and drip groove protects the pier top from rainwater. Pyramid-shaped caps and ball finials are also popular for a more formal appearance.
