PERTH, SCOTLAND PROJECT OVERVIEW The underpass provided is part of the Perth Town Lade footway/ cycleway / equestrian route which support the new B9993 Ruthvenfield Link Road. The original design was an asset MultiPlate arch sitting on top of the Lade culvert. PROBLEM SOLVED During the design process, the underpass’ location moved and is now parallel to, but higher in the embankment than the Lade culvert. With asset’s value engineering input, a closed ring structure is chosen to eliminate the needs of foundation slabs. asset MultiPlate MP200 UnderPass length: 58.25m.

WOKINGHAM, BERKSHIRE PROJECT OVERVIEW asset International Structures Ltd were commissioned by consulting engineers Stuart Michael Associates to design, and groundworks contractor Hope & Clay Construction to supply 1 single E66T cut off asset BEBO arch structure, 1 twin E66T cut off asset BEBO arch structure, and 600m2 of asset VSoL retained earth walls and copings for a 400 mixed housing development for Bovis Homes and Persimmon homes, which was adopted by Wokingham Borough Council.

ENNISCORTHY, IRELAND PROJECT OVERVIEW asset International Structures Ltd were commissioned by consulting engineers RPS and ARUP to design, and civil engineering contractor BAM DRAGADOS to supply in excess of 10,000m2 of asset VSoL retained earth walls for 32no structures for road, rail and river crossings for the M11 Gorey to Enniscorthy PPP scheme, which was adopted by Transport Infrastructure Ireland. The scheme comprises of a new motorway from the end of the Gorey Bypass at Clogh to the townland of Scurlockbush, south of Enniscorthy. The scheme also includes a bypass of the N30 to the west of Enniscorthy and a link road to the N80. PROBLEM SOLVED The realigned route will comprise the provision of approximately 27 km of M11 Mainline, with a standard dual motorway carriageway type. In addition, approximately 8 km of single carriageway will be constructed to bypass Enniscorthy to the west, by linking the existing N11 to the existing N30 and also approximately 4 km of dual carriageway link road will connect the existing N11 / N80 junction north of Enniscorthy to the M11 Mainline.

TORRE STATION, TORQUAY PROJECT OVERVIEW The project was based near Torre Station, Torquay, a Great Western Railway-managed and Grade II-listed station. We were initially contacted to look at the suitability of utilising our asset BaFix & Sleeve-It system, a proprietary system designed to stabilise railway tracks, for a 200m run of track along the edge of a retaining wall to a small stream. The driver for this work was that ballast was falling into the stream, restricting flow and increasing the risk of flooding. Clearing of the stream was also becoming a regular occurrence, which took considerable time and resources to undertake. PROBLEM SOLVED 220m of asset BaFix 70 and 147 Sleeve-It units, along with handrails, were installed along the edge of the track, increasing track resilience. Once the installation was complete, the ballast was replaced, and cable troughs were reinstated. The associated handrailing was an additional feature of the project, establishing an essential position of safety. ESG The project not only provided an environmental benefit by mitigating the flood risk, but also had a significant social impact. By preventing the loss of ballast into the stream, the project ensured that the train operating companies, commuters, and tourists using the line into Devon and beyond were not negatively affected. This, in turn, contributed to the local economy by maintaining the smooth operation of businesses in the area, thereby reinforcing the project's value and importance.

MACROOM BYPASS, IRELAND PROJECT OVERVIEW The N22 Macroom Bypass project features the construction of a 22km dual carriageway, constructed offline of the existing N22. The project has 130 structures including river crossings, road underbridges, culverting and underpasses. Asset International Structures Ltd secured 29 asset VSoL wall structures totalling approximately 10,000sqm of cross panel, along with 12 asset BEBO arch culverts with precast head and wing walls. The asset BEBO arch structures form flood relief culverts for flood balancing on either side of the main highway. PROBLEM SOLVED The asset BEBO arch provided cost savings to the project as a result of less precast material being needed. The asset BEBO bottomless culvert reduced the requirement for in-situ concrete, and provided a fully modular precast culvert system to benefit program and plant requirements. To help improve health and safety onsite, AIS offered the asset BEBO arch units with waterproofing already applied to concrete surfaces prior to delivery to site. This ensured that the process could be carried out efficiently in a controlled factory environment. It eliminated the need for working at height, as well as the associated health and safety risks. ESG The asset BEBO solution offered carbon savings for the project due to the reduced number of culvert crossings, leading to less material requirements. The environmental benefit (compared to the alternative solution) was a key factor in the adoption of asset BEBO for this project. The asset VSoL walls also reduced the site program and added social benefit to the scheme by reducing the environmental impact on the local community. The solution eliminated the need for onsite activities such as concrete pours which would have increased site traffic and noise pollution to the surrounding community. Environmental Product Declarations (EPDs) for both our asset BEBO Arches (GWP Total: 435kg CO2 per 1m3) and VSoL Retained Earth Wall Systems (GWP Total: 278kg CO2 per 1m3) enable us to demonstrate our commitment to carbon reduction within our concrete products.

FLEET, HAMPSHIRE PROJECT OVERVIEW The picturesque Hartland Village based in Fleet, Hampshire, utilises a triple span asset BEBO E24 structure, to provide an attractive access road to a housing development. Differing sized asset BEBO Arches have been used to create an aesthetic humpback feature bridge, which has been brick clad to a contemporary finish.   The bridge is situated over a man-made lake at the lakeside area entrance, and features built-in lighting columns that blend in perfectly with the new residential environment. The aim was to create a showpiece bridge structure as a gateway to this prestigious housing development. The original concept for this project was to mimic a contemporary masonry arch viaduct crossing a watercourse. PROBLEM SOLVED This structure is a perfect example of the benefits of replacing an in-situ solution with a modular precast system. AIS facilitated a design change to the modular asset BEBO system that improved programme compared to the in-situ solution. Another challenge we overcame by installing a precast system during winter was weather and temperature issues, which would have caused curing problems, had the concrete been mixed and poured on site. ESG From an ESG perspective, the off-site manufactured solution improved health and safety on the project by removing the risk of labour-intensive activities next to a watercourse. AIS are committed to reducing the environmental impact of our products and investigating innovative ways of producing asset BEBO arches.

GLENMORISTON ESTATE, SCOTLAND PROJECT OVERVIEW Our client's designers proposed using an asset MultiPlate arch for a water crossing, which forms part of the main access route to Bhlaraidh Wind Farm (located on the Glenmoriston Estate, Scotland). asset International Structures Ltd were responsible for the design and supply of the steel arch, and made our proposal to the framework contractor.   The chosen solution was an asset MutliPlate MP200 corrugated arch (approx 9m span) which has a 50-year design life. PROBLEM SOLVED The corrugated steel structure allowed for further construction traffic to facilitate the building of a new substation, which enabled construction to continue without disruption or delay. Utilising over 65 years' experience in offering flexible steel designs in a variety of applications, the asset MultiPlate arch acts as the main route access to the site. ESG The lightweight structure didn't require heavy lifting on site, improving health and safety. The open-bottomed arch helped to retain the natural watercourse and protected the stream bed. The lack of an enclosed structure meant that work was carried out to SEPA (Scottish Environmental Protection Agency) guidelines.

CHAPEL ROAD, CAMBOURNE (CORNWALL) PROJECT OVERVIEW We were approached to design and supply a concrete bridge structure over a carriageway parallel to a watercourse, along with a live road running over the top. As the exclusive BEBO licensee for the UK and Ireland, delivering precast arch structures since 2006, we proposed an asset BEBO twin arch solution for the project. A C42 Twin BEBO Arch with VSoL rectangular panels and N2 containment precast parapets was chosen as the suitable solution, which is located in Chapel Road, Camborne (Cornwall).   Our project brief was to mirror an old masonry bridge structure using local granite, creating a heritage aesthetic sympathetic to the local infrastructure of the area. This project is particularly significant, as 2025 marks the 10 years anniversary of the bridge installation. PROBLEM SOLVED The main challenge that we faced was how we delivered the complex system in a timely and safe manner. The high quality, off site manufactured modular precast units were delivered to site in sequence, providing an efficient installation and a safe working environment. The flexibility of the robust solution also allowed for fixing the heavy granite stone directly to the precast structure, creating the desired aesthetic and structural requirements as per the initial project brief. ESG The asset BEBO twin arch addressed numerous ESG concerns, as follows:   Social connectivity - connecting travel routes from wider communities to Chapel Road Utilising local stone - by supporting regional businesses, with the aim of producing a consistent aesthetic Protecting local wildlife - within the watercourse running beneath the concrete arch Traffic management - reducing impact to commuters and alleviating disruption to traffic

ANSTRUTHER, SCOTLAND PROJECT OVERVIEW Kilrenny Bridge carries the A917 over Kilrenny Burn in Anstruther. The reinforced concrete bridge was built in 1937 over the top of the original, narrower, masonry arch bridge. During a programme of council-wide bridge assessments and a 17-tonne weight restriction, the bridge was found to be weak.   The scheme involved building a lightweight asset MultiPlate arch under the existing bridge and infilling between the two structures with concrete. This meant that the 1937 concrete bridge could be left in place but would become structurally redundant. The abutment walls from the old masonry arch also had to remain in place (with minor adjustments), avoiding the need to divert Kilrenny Burn. The remainder of the external faces were to be clad in natural stone. PROBLEM SOLVED By Fife Council adopting the asset MultiPlate solution, this resulted in substantial cost savings due to the works being completed with only 3 nights of road closures, necessary for the resurfacing works to be carried out. Key benefits of the works include significantly less disruption to traffic and the local community. ESG Environmental aspects highlighted during an environmental survey have been considered by the inclusion of a mammal pass near the main culvert. This quick and efficient installation also had a positive impact on social value and connectivity due to the modular nature of asset MultiPlate. The road is now open to two-way traffic, and one footway is even wide enough to accommodate a potential cycleway extension in the near future.

NEWPORT, SOUTH WALES PROJECT OVERVIEW We were approached to offer a solution for the Stephenson Street Pedestrian Access Ramp Project. The initial specification called for a steel structure to form the access platform and staircase structures in a flood plain area, adjacent to the River Usk in Newport, South Wales.   AIS produced a concept solution for the project that meets the geometric criteria, as well as offering additional benefits to the scheme by utilising asset FRP as an alternative material. The decision to pursue an asset FRP solution was driven by specific project challenges; remote access, ground conditions, aggressive environment in the tidal estuary, enhancing public safety by incorporating a non-slip finish. PROBLEM SOLVED The asset FRP solution combines beams, parapet sections and deck panels, ensuring that all structural members are steel-free. The lightweight proposed asset FRP solution addressed project challenges with difficult ground conditions. The substructure requirement was minimised against a steel structure by reducing material and plant requirements. Lightweight and modular, asset FRP Bridges have many benefits over traditional structures. The modular system was easy to install, as sections were bolted together to form the complete system. The asset FRP structure has a 6m x 5m midsection and two ramps equalling 62.5m, with an average weight of 118kg per meter. The raised platform above a flood wall is virtually maintenance free throughout the 50-year design life. ESG Due to the project location within a tidal flood zone, asset FRP has the benefit of being corrosion resistant. asset FRP is a lightweight material typically offering a 40% weight saving against steel structures. This reduces the installation equipment required on site along with the haulage demand, reducing the environmental and social impact of the project.
