Infrastructure
Infrastructure Built by One Accountable Team
From S278 junction improvements to footbridge replacements, we deliver highways and infrastructure packages with our own teams, plant and supervision across the South West and South Wales. One contractor, one point of accountability.

The brief
One team across the whole package
Infrastructure packages come apart at the interfaces. A typical S278 scheme involves earthworks, drainage, ducting, kerbing, surfacing, signals and traffic management, and when each element sits with a different subcontractor the main contractor ends up managing the gaps. Programme slips at every handover, defects go unowned, and the highway authority sees a different face each week.
We take the whole package and build it with our own people. EJ McGrath self-delivers highways and infrastructure works across the South West of England and South Wales with our own teams, plant and supervision, nothing passed down a chain. Within one package that typically means:
- S278 and S38 agreements, junction improvements and signal civils
- Active travel schemes, cycleways and new footways
- Bridges, retaining structures and reinforced concrete
- Highway drainage, ducting and utility diversions
- Earthworks, surfacing and road markings
How we run it on site
Live highways work is won or lost in the phasing. We plan traffic management, working windows and inspection hold points before an excavator arrives, coordinate utility diversions early and sequence the works so each phase hands over clean. Where we are digging around live services, our own T-VAC 2 vacuum excavation unit proves and exposes apparatus without risk to the asset. Everything is CDM-compliant and QA-led, with inspection and test records kept as the job goes, not reconstructed at handover.
The record backs it up. We have delivered city-centre bus infrastructure civils, S278 packages on major developments, an EV charging hub and campus infrastructure works, and replaced two footbridges with FRP structures on an eight-week programme, with temporary works over a live watercourse.
Most of our work comes from main contractors such as Kier, BAM Nuttall and Galliford Try, and from public authorities including North Somerset Council. Much of it is repeat business, which tells you how those jobs went. If you have a highways or infrastructure package anywhere in the South West or South Wales, we will price it, plan it and build it with one accountable team.

Why EJ McGrath
Built for complex, self-delivered work
One accountable package
Earthworks, drainage, structures and surfacing delivered by our own teams under one supervisor. No gaps between subcontractors, because there are no subcontractors.
Safe around live traffic
CDM-compliant and QA-led, with traffic management and phasing planned before we break ground. SSIP, Constructionline Gold and SMAS Worksafe accredited.
Trusted by the majors
We deliver infrastructure packages for Kier, BAM Nuttall and Galliford Try, and directly for councils. Most of it is repeat work, which tells you how the last job went.

On site
Phased around live traffic and the public
Infrastructure jobs live and die by phasing. We agree the traffic management strategy and working windows with the client and the highway authority up front, then break the works into phases that keep traffic, pedestrians and businesses moving throughout. Hold points and inspections are built into the programme, not bolted on.
Because our gangs handle the earthworks, drainage, concrete and surfacing themselves, the interfaces between trades are managed inside one team under one supervisor. That is where most highways programmes leak time, and ours has no gaps to leak through. Utility diversions and stats liaison are coordinated early so third-party works do not sit unmanaged on the critical path.
We turn up with our own excavators, dumpers and operators, our own supervision and our own T-VAC 2 vacuum excavation unit for working around live services. A recent pair of footbridge replacements shows the approach: temporary works, a live watercourse and an eight-week programme, delivered by one crew from closure to reopening.
