Civil engineering consultancy

Civil engineering.From design to site.

We design roads, drainage and earthworks, coordinate designs in 3D and support construction on site.

Tell us what you need.
We’ll agree how to help.

Whether you are starting a project or need help with a specific task, we review the available information with you. Before starting, we agree the scope and the documents you need.

01

Review the starting point

We review the drawings, survey and project constraints to identify missing information and issues to resolve.

02

Agree the scope

We agree tasks, deliverables and deadlines to suit you and the wider team.

03

Design and coordinate

We prepare the agreed design and documentation, coordinating interfaces with other disciplines.

Practical support
for your project.

We can take on a specific task or support your team across several disciplines.

01

Road infrastructure

We design roads, roundabouts and access routes, with alignments, gradients and cross-sections suited to the site and intended use.

02

Drainage and sewerage

We assess how to collect and convey water, design drainage and sewer networks, and check their capacity.

03

Terrain modelling

We define platforms, levels and slopes, calculate earthworks and adapt the design to the topography.

04

Green infrastructure

We integrate sustainable drainage to retain, infiltrate or convey rainwater, according to site conditions.

05

3D modelling and BIM coordination

We model terrain, roads and utilities in 3D to check how they fit together. During design and construction, we help identify clashes and review solutions before they are built.

06

Construction supervision and monitoring

We support construction with site visits, work inspections and help resolving issues. Aerial imagery and progress comparisons can complement site monitoring.

07

Technical tender submissions

We review the tender documents and prepare the technical submission with your team, explaining the proposed methods, organisation and programme to meet each tender’s requirements.

08

Site surveys and setting out

We measure points and levels, set out elements and check their construction. We prepare information for as-built drawings and volume calculations.

Answers to common questions about working together.

Can you help with just part of a project?

Yes. This might be a road design, drainage, terrain modelling or BIM coordination. We agree the tasks with you and how they fit with the wider team’s work.

What information do you need to scope the work?

The location, project stage and a description of what you need. If you have drawings, surveys or models, attach them to your email and include your intended deadlines.

What will you deliver?

This depends on the service and project stage. Before starting, we agree which drawings, calculations or models we will prepare and the delivery formats.

What do you need to prepare a technical tender submission?

The tender documents, available design or technical information, and submission deadline. We review the sections you need and the company information to include in the bid.

Need support
with your project?

Tell us the project location, its current stage and what you need help with. Include your target date if you have one.
