# Bridge and Viaduct Engineering and Design

![Bridge and Viaduct Engineering and Design](https://www.systra.com/uk/wp-content/uploads/sites/11/2023/06/bridge-and-viaducts.jpg)

**The multi-disciplinary team at SYSTRA has a distinguished track record of supporting bridge and viaduct design, engineering and maintenance – helping asset owners to build, assess and manage every type of bridge structure throughout the asset lifecycle.**

### Managing essential bridge and viaduct infrastructure

Bridges and viaducts come in a huge variety of structural forms, sizes and
models, which require specialist expertise to design, maintain and inspect. From
segmented concrete and post-tensioned bridges to long span, movable and heavy
freight bridges, the challenges of building and looking after these essential
structures are as varied as the bridges themselves.

Bridge owners, infrastructure operators and developers need expert help to
understand the statutory requirements and technical challenges associated with
building and maintaining bridges and viaducts. Access to capital to fund bridge
projects is a significant challenge, as is access to materials, labour and
professional design expertise. Bridge owners need to consider not only safety
and structural integrity, but also resource efficiency and carbon reduction in
the way bridges are designed, managed and maintained.

Bridge owners, developers and managers can find all the expertise they need at
SYSTRA. Our bridge and viaduct specialists offer all the professional services
required to inspect and assess existing bridges, to re-engineer bridges for
strengthening or enhancement, and to design brand new bridges as part of
infrastructure development projects.

**SYSTRA provides comprehensive bridge inspection, assessment and design services for new and existing bridges and viaducts, including road, rail and pedestrian structures.**

### Bridge and viaduct design services

SYSTRA bridge specialists are part of a global network of bridge engineers who
work together to support all types of bridge and viaduct construction and
engineering. Our knowledge and expertise enable us to support clients from the
concept design stage through to construction. We carry out feasibility studies
at the planning stage to assess the viability of proposed schemes, and applying
the principles of
[ modern methods of construction](https://www.systra.com/uk/services/modern-methods-of-construction/)
to optimise bridge designs at the early stages of a project.

We design for construction, often within constrained time periods dictated by
possession windows on essential infrastructure projects. Our bridge designs
focus on efficiency and structural optimisation, helping clients to manage
capital and operational expenditure.

We embed sustainability into our projects, providing optimal solutions without
compromising the programme or budget. Our expertise in carbon calculation and
assessment helps us to design bridges in a way that minimises resources and
whole-life carbon emissions. We also design for safety, taking into account
construction sequencing, as well as future maintenance and inspection
requirements.

### Bridge condition monitoring and assessment

Bridge and viaduct inspection and assessment is a major part of our work. Our
integrated team has a detailed understanding of historic structure behaviour,
giving us the assessment capabilities to maximise the capacity of existing
structures, and to advise on strengthening and enhancement works. We understand
the asset management process and client needs, and all assessments are carried
out in accordance with guidance documents from the asset owner or Network Rail
standards, as appropriate.

We have a proven track record of undertaking structural assessments on a wide
variety of simple and complex bridge structures. Our experience includes
assessing many railway bridges of varying complexity, form and loading
requirements. We use the latest technology in our bridge surveys and inspections
to achieve the most accurate assessments and improve asset management
decision-making.

### Our bridge inspection and assessment work includes:

- Inspecting bridges to both Principal Inspection and Inspection for Assessment
  levels.
- Supervising specialist investigation contractors.
- Assessing bridges to current DMRB standards to determine load capacity.
- Recommending remedial measures to improve the capacity of bridges.
- Designing and specifying remedial strengthening measures.
- Advising on maintenance requirements, scheduling and prioritisation.

### Digital modelling to optimise bridge design

SYSTRA has long experience of working with Building Information Modelling (BIM)
to support bridge and viaduct design, and to create and manage digital asset
information through a centralised dataset. Our in-house digital information team
continuously tests new software and advises our bridge teams on cutting-edge
systems – ensuring we remain at the forefront of digital innovation in bridge
design and assessment.

### Design for ancillary structures

In addition to rail and highway structures, we have extensive experience in
designing ancillary structures such as car parks, skateparks, drainage
structures, retaining walls and foundations for major traffic signs, CCTV masts
and variable message signs.

We’d love to help with your next project
