Lifespan Structures

Lifespan Structures are able to develop a conceptual design for both new and replacement bridges using FRP structures, simplify the design and procurement processes in line with BD90/05 Design of FRP Bridges and Highway Structures and allow clients to procure long lasting, cost effective structures without the costly ongoing maintenance.

Outline Proposals

With the bridge deck dimensions we can quickly provide an outline proposal for consideration which can include a schematic drawing and parapet options.
Budget Costs

Budget Quotes

Given the loading requirements we can usually provide a budget quote in a week which will include delivery costs to site, bridge dimensions and approximate weights.

Tender Prices

Lifespan Structures provide design and manufacture tenders either direct to end users such as Local Authority Councils or via main contractors. We also provide design tenders as a sub consultant.

Bridge Design

Lifespan Structures design the FRP composite decks to suit our manufacturing processes and for efficient use of the materials. AIP certification and design checks are also available if required.

Bespoke Structures

Each bridge is individually designed and manufactured for the specific requirements of our client in terms of live loading, dimensions, parapet detailing, surfacing, longitudinal camber and colour.

CPD Seminars

As part of our service to the construction industry we provide CPD seminars to Local Authorities and Consultants to explain how FRP composites are used for the construction of bridge decks and the benefits.

About FRP

FRP composites are a combination of fibres which provide the strength and resins which transfer the stress between the fibres and protects them. This structural material was developed over 70 years ago and is widely used in many industries including automotive, marine and aeronautical.



FRP composites are lightweight structural materials so our bridge decks are less than half the weight of steel or timber bridges making them easier and safer to install.


These materials have been in use for over 50 years in all types of industries including the marine and wind energy sectors. They are renowned for their durability in aggressive environments.

Capital Cost Effective

FRP bridges are similar in cost to steel and timber alternatives. The lower dead load also reduces the cost of the abutments and installation costs.

Simple Procurement

We just need the bridge dimensions and load cases. We can provide AIP documentation and design checks if required. It can be a two stage procurement for initial design followed by manufacture and delivery or one stage.

Fast Installation

installation contractors prefer our bridges because they are delivered to site in one piece complete with surfacing and the supplied parapet is easily bolted to the deck. The bridges can be lifted into place in less than an hour often using a tracked excavator.

Low Maintenance

Designed to last in excess of 60 years with minimal maintenance. Depending on traffic use the resin surfacing may need to be overlaid and after 25 years you may wish to repaint but otherwise just power wash.


The carbon and energy embodiment from manufacture is much lower than steel and comparable with timber. We are starting to use bio resins in the manufacture which will reduce the environmental footprint even further.
Offsite Manufacture

Offsite Manufacture

The construction industry is tasked with using more offsite manufacturing to improve efficiencies, speed of delivery, and improve quality. All our decks are made in our factory and delivered to site complete and ready for installation.


The slender nature of the deck and the choice of colours, parapet types, surface finishes and deck radius allows our clients, with their local stakeholders, to choose the final appearance of the bridge to match the surrounding environment.
