Civil Engineering

Civil and infrastructure engineering for bridges, highways, drainage and rail, from assessment to detailed design.

Civil Engineering

What we cover.

Our civil work covers the structures and infrastructure that carry movement and water. We assess and design bridges, highway structures, drainage and earthworks and rail structures, with the durability and long-term performance these assets demand.

In detail

What civil engineering actually involves.

Where structure meets ground

Civil engineering is where structure meets the ground, the water and the movement of people and vehicles. Our civil work covers the assets that have to perform for decades under load and weather: bridges and their assessment, highway structures, drainage and earthworks, and rail structures. The common thread is durability, these are not elements you replace easily, so whole-life performance drives the design.

Assessment and design

On existing bridges we carry out assessment to determine the safe load capacity and condition, then design strengthening or repair where the numbers demand it. On drainage and earthworks we design to manage water and ground movement as part of the wider development, coordinated with the structural and highway elements so nothing is engineered in isolation. Everything is designed to the Eurocodes and the relevant asset-owner standards, because a highways authority, Network Rail and a private developer each check against different rulebooks.

How Lead Group helps

We assess existing bridges and structures for safe capacity, design the strengthening where the numbers require it, and handle the drainage and earthworks around them. Because the same practice does the structures and the civils, the interface between them is our problem rather than something you coordinate.

How we work

Do you assess existing bridges?

Yes. We carry out bridge assessment to determine load capacity and condition, and design strengthening or repair where it is needed, to the relevant standards for the asset.

Standards & codes

The codes behind civil engineering.

Eurocodes 0-9 & UK National Annexes

BS EN 1990 through BS EN 1999 govern the basis of design, actions, and the design of concrete, steel, timber, masonry and aluminium structures. Every calculation we issue references the relevant Eurocode part and its UK National Annex, and states which parts were applied.

Analysis, design & drafting software

Structural analysis and design in Tekla Tedds and Tekla Structural Designer, with Autodesk Robot, CSC Fastrak, CSC Portal Frame, MasterSeries and Hilti Profis used where a scheme suits them. Drawing production in AutoCAD, and modelling in Autodesk Revit where a project is delivered in BIM. Output is issued as readable calculations rather than raw software printouts, so a checker or a building control officer can follow the reasoning.

Approved Document A (Structure)

The Building Regulations requirement your local authority Building Control checks against. Our calculations and drawings are prepared to demonstrate compliance so your submission is accepted without back-and-forth.

Professional indemnity insured

Every report and calculation package is backed by professional indemnity cover, which is what lets a lender, Building Control or another engineer rely on it.

Process

From enquiry to sign-off.

Enquiry

Send drawings or describe the problem. We confirm the scope, the deliverables and a target timescale.

Information

We agree the survey, drawings or data we need and any site access required.

Engineering

Design, calculation or assessment to the relevant Eurocodes and UK National Annex.

Issue

A clear, defensible report or set of calculations, with assumptions and limitations stated.

Selected work

Real structures, surveyed and engineered.

Questions

Common questions

What standards do you design bridges to?

We design and assess to the Eurocodes and the relevant national and asset-owner standards, depending on the structure and who maintains it.

Can you design drainage and earthworks?

Yes. We design drainage and earthworks as part of infrastructure and development projects, coordinated with the structural and highway elements.

Do you work on rail structures?

We assess and design railway structures, working to the standards required by the infrastructure owner.

Do you carry out bridge assessments for load capacity?

Yes. We assess existing bridges to determine their safe load capacity and condition, and design strengthening or repairs where required, to the standards the asset owner uses.

Can civil and structural be handled by one practice?

That is exactly our model. Keeping civil and structural under one roof means the drainage, earthworks, foundations and superstructure are coordinated rather than clashing on site.
