About GSB

An engineering design consultancy for infrastructure and property.

GSB Eng UK Ltd is a civil and structural engineering design consultancy specialising in ancillary and infrastructure works across rail, energy and property across the full project lifecycle — from feasibility through to construction support.

Who we are

Practical, buildable and on programme.

We design, check and support delivery of the ancillary civil and structural works that keep the railway running — the schemes that must be right first time but rarely make the headlines. Alongside our rail work, we deliver structural engineering and drainage design for commercial and residential buildings.

The team combines over 25 years of rail engineering experience with hands-on knowledge of station environments, lineside constraints and the realities of construction in live operational settings.

Our values

Three principles that shape every project.

Excellence

Master the detail. Get the engineering right the first time.

Collaboration

Work as one team with contractors, designers and operators.

Proven

Track record across the most demanding rail and infrastructure schemes.

Our approach

How we deliver — without unnecessary layers.

We work seamlessly alongside contractors, utilities and operators. Where a project requires disciplines beyond our in-house team, we draw on a trusted network of specialist partners — giving clients a single coordination point.

  • Safety and constructability are built into design from day one — not bolted on at review.
  • Tailor each scope to the project rather than applying a generic template.
  • Single point of coordination across civil, structural, drainage and utility disciplines.
  • Tight programmes met — responsive, adaptable, no unnecessary layers.
