Our Engineering Disciplines & Specialisms

Filter by discipline cluster to examine detailed technical scopes, Network Rail standard alignments, and client deliverables.

1. Civil Engineering

Ancillary civil design solutions for mainline rail and TOC facilities. Delivering under-track crossings (UTX/URX), platform gauging extensions, level boarding modifications, retaining walls, cable routes, and relocatable equipment building (REB) slab foundations.

  • Platform copers, overlays & DDA level boarding
  • Under-track cable crossings & thrust-bored sleeves
  • Lineside retaining walls & reinforced earth slopes
  • Walkways, RRAPs & lineside containment troughs

2. Structural Engineering

Comprehensive inspection, assessment, refurbishment, and replacement of operational rail overbridges, underbridges, footbridges, and complex station canopies. Specialising in NRSD Type-E steel half-through bridges and precast concrete decks.

  • Full Form A & Form B design certification
  • Finite Element Analysis (FEA) residual load ratings
  • Heritage ornate cast iron and wrought iron repairs
  • Signal gantry & canopy-mounted cantilever designs

3. Geotechnical Engineering

Providing crucial subsurface intelligence from early optioneering through to construction. Conducting Ground Investigation Reports (GIR & GDR), slope stability assessments, pile cap engineering, guided auger boring beneath live rails, and flood scour mitigation.

  • Ground Investigation Reports (GIR & GDR)
  • Guided auger-bored crossings under live tracks
  • Driven & CFA piled foundation designs
  • Floodplain scour modelling & rip-rap protection

4. M&E Building Services

Full suite of mechanical, electrical, and public health installations for operational depots, passenger interchanges, and maintenance sheds. Managing DSEAR/ATEX Zone 1 hazardous areas, UK Power Networks (DNO) interfaces, and BS 7671 electrical compliance.

  • DSEAR/ATEX Zone 1 hazardous area fuelling & CET
  • Substation load analysis & DNO applications
  • BS EN 12464-2 compliant low-level walkway lighting
  • 3-hour static inverter emergency lighting systems

5. Carbon Assessments & Net Zero

Supporting the rail sector's journey to Net Zero through our ICE Carbon Champions recognized Capital Carbon Assessment Tool. We quantify embodied and operational emissions from early optioneering to recommend material substitutions that reduce carbon by up to 40%.

  • Whole-life Capital Carbon calculations
  • PAS 2080 carbon management compliance
  • Low-carbon precast & modular materials optioneering
  • TOC facility energy decarbonisation roadmaps

6. Digital Engineering & BIM Level 2

Contemporary digital engineering workflows using Bentley AECOsim (MicroStation), ProjectWise, and eB. Delivering clash-free federated 3D models, digitised utility asset registers, kinematic gauging simulations, and 3D visual fly-through animations.

  • BIM Level 2 federated information management
  • Automated CAD signal sighting & clearance analysis
  • Point-cloud scanning & motion-based asset capture
  • Digital twinning & as-built documentation

7. Temporary Works Design

Engineering safe, efficient temporary works schemes that enable construction of permanent infrastructure during compressed possession windows. Designing crane outrigger pads, proprietary shoring, temporary cable diversions, and platform propping systems.

  • Kirow rail crane lift pad & outrigger design
  • Trench shoring & excavation support near tracks
  • Temporary cable suspension bridges over rivers
  • Emergency structural propping for cracked columns

8. Composites & Modern Materials

Designing lightweight, corrosion-resistant footbridges and ancillary rail structures using glass-reinforced polymer (GRP) and advanced composites. Eliminating touch-potential risks near 25kV OLE lines while reducing structural self-weight.

  • Non-conductive GRP cable support tubing
  • Composite platform overlay planks & ramps
  • Corrosion-proof lightweight footbridge spans
  • Touch potential mitigation shrouds for OLE masts

9. Multidisciplinary Integration

Delivering complex rail renewals through integrated in-house teams. We act as the single point of engineering accountability for schemes combining track, civils, structures, signalling sighting, OLE, and station architectural interfaces.

  • Lead Design Organisation (LDO) coordination
  • Comprehensive GRIP 3 to 8 lifecycle management
  • Multidisciplinary cross-check verification
  • Single accountable contract interface for Tier 1s

10. Technical Advice & BAPA Leadership

Chartered CRE (Design) and CEM leadership, Network Rail Basic Asset Protection Agreement (BAPA) guidance, independent Category 3 structural checks, and client-side secondments to oversee complex lineside assets and evaluation schemes.
