Infrastructure & Drainage
The moment that matters
Most projects have a point at which infrastructure catches up with the vision. Sometimes that moment is smooth. Sometimes it is not: the junction geometry a highway authority will not accept, the drainage outfall that conflicts with the ground conditions, the road gradient the topography will not allow. These problems are manageable when they arrive at the design stage. Once the masterplan is fixed, they become expensive.
Getting infrastructure thinking into the design at the right moment, early enough to shape the masterplan rather than respond to it, is what turning a project into impact actually requires. That is where our work begins.
Principled engineering
The quality of infrastructure design is not measured in margin. It is measured in specificity: knowing which details determine whether a scheme will be adopted, whether the drainage performs, whether the programme holds. Over-specified design adds cost without adding certainty. Under-detailed design adds risk that nobody notices until the contractor is on site.
Principled engineering means working to the right standard for the purpose, knowing where the adopting body will hold the line, and designing to that line with enough precision that the approval process moves efficiently and the construction that follows it does not need to be revised.
The best infrastructure design is invisible. It delivers the masterplan vision without announcing itself, holds the standard without unnecessary margin, and performs without needing to be revisited
Where ambition becomes real
A transport vision and a flood risk strategy are, until someone engineers them, ambitions. The movement framework needs to become a highway that can be adopted. The water-positive masterplan needs to become a drainage system that performs. Infrastructure & Drainage is the discipline that makes that crossing, from what the design proposes to what can actually be built.
That is the role the whole scheme depends on. The junction geometry, the outfall depth, the cut and fill balance: these are the decisions that protect or compromise everything the other specialisms have worked to establish. It is only when the engineering carries them well that the whole scheme delivers its purpose.
That is why our three specialisms are most effective when they share the same understanding of a site from the start. Not as separate consultants briefed in sequence, but reading the same place, asking the same questions, at the same time.
In practice
Whether it is highway and access design for a planning application, surface water and foul drainage strategy, SuDS design, section 38 or section 278 agreement preparation, cut and fill modelling, or on-site supervision through to as-built completion, our approach carries the same engineering precision from the first sketch to the final sign-off.
The evidence for what that precision produces is in the schemes themselves: designs that hold, construction programmes that hold to programme, places that perform over time.
Route to conversation
Every vision in the planning system eventually reaches the point where it has to become something physical. That is the moment when the quality of the engineering, and the willingness to find the right answer rather than the standard one, determines whether the scheme delivers what it promised.
If you need engineering that does not see things in black and white, that understands its role is in service to the vision and the specialisms working to realise it, and that works to unlock the potential they see in a place, let’s talk.
Where we work
We work across residential, commercial, health, education, infrastructure, renewables, retail and leisure, and wherever work takes us beyond that list. Every project builds on an established body of knowledge: how to use the planning system to a client’s advantage, what creates places that hold their value, and where early decisions protect against risk and leave a legacy that matters beyond completion.
Those learnings cross every sector boundary. What we take from a residential scheme shapes how we approach a commercial one. What we learn in one planning authority informs how we navigate the next. That accumulated intelligence is what you’re drawing on, whatever the brief.
The sector shifts. The thinking doesn’t.
Residential
We’re often involved early in projects, supporting site-finding activities, and moving on to the masterplan process. Schemes range from a few dwellings with simple access and layout considerations, through to large, mixed use schemes requiring modelling of the wider network and strategic infrastructure improvements.
Renewables
We support development for wind, solar and energy-from-waste projects throughout the UK. This includes large scale wind farms to expansive solar schemes in areas of risk of flooding. As a corporate IEMA partner, we understand the specific legal requirements of environmental impact assessment.
Commercial & Industrial
Whether it’s transport planning or highway design, flood risk or drainage strategies, we understand the nuances of industrial and commercial development. We can take a lead role in optimising the masterplan process, support planning with robust evidence, and provide accurate, cost-effective construction designs.
Retail
We’re a trusted partner for a number of regional and national developers, bringing extensive knowledge of commercial development. We enable a scheme to be commercially optimised, understanding the importance of maximising passing trade; while also minimising the severity of associated traffic effects.
Health & Wellbeing
Our team of experts has extensive experience of advising on all types of health and wellbeing facilities. We provide transport planning, highway, flood risk and drainage input across a range of developments, including primary and secondary schools, GP surgeries, pharmacies and dental practices.
Leisure
Every leisure development is different – whether it’s a new campsite, gym or stadium. The journey through the planning system is just the start. We ensure that fundamental engineering principles are ingrained in our solutions, to expedite the design and approval stages, and get contractors on site sooner.
