Bridges

Structural crossings built to span, endure, and carry.

We design and build bridges across road, rail, and active travel networks — from standard highway crossings to complex long-span structures, all engineered for a full design life with minimal maintenance.

Overview

What We
Build

Bridge construction requires the integration of structural engineering, geotechnics, materials science, and construction methodology into a single coherent programme. We deliver bridges that meet loading standards, durability requirements, and inspection access needs — while working within the constraints of live traffic, waterways, and complex land ownership.

Our bridge capability spans new construction, refurbishment, and strengthening works — helping asset owners extend the life of existing structures as well as delivering new crossings from design through to handover.

Capabilities

What We Deliver

Road Bridges

Highway bridges designed to BD/EN standards — accommodating live loads, dynamic vehicle impacts, and long-term durability in exposed environments.

Rail Bridges

Bridges and viaducts for heavy rail, light rail, and metro applications — engineered for dynamic train loading, vibration limits, and Network Rail requirements.

Pedestrian & Cycle Bridges

Footbridges and active travel crossings combining structural efficiency with aesthetic quality — designed for dynamic resonance, vandal resistance, and low maintenance.

Refurbishment & Strengthening

Assessment, repair, and strengthening of existing bridge stock — extending asset life, increasing load capacity, and bringing structures up to current standards.

Standards

Structural Standards
We Design To

HA+45

Highway Loading

Road bridges designed to HA uniformly distributed load combined with 45-unit abnormal vehicle loading to BD37/EN1991-2.

120yr

Design Life

Major bridge structures specified for a 120-year design life with inspection and maintenance regimes built into the design.

RU/RL

Rail Load Models

Rail bridges analysed to UIC Load Models 71 and SW/0 with dynamic factors applied for high-speed compatibility.

f ≤ 5Hz

Pedestrian Resonance

Footbridge natural frequencies tuned to avoid resonance with human walking and jogging paces per BD29 and EN1990.
