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.

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.

RIVER TAY, SCOTLAND PROJECT OVERVIEW asset International Structures Ltd were approached to design and supply a 30m span, 600mm thick asset BEBO arch (T-Series T94) with bevel ends. The arch forms part of a green bridge running over the main highway, connecting wildlife and creating a safe haven for animals. The structure is situated near the banks of the River Tay (which is the longest river is Scotland, north of Perth), and has been developed as part of a wider scheme by Perth and Kinross Council. A bridge abutment using the asset VSoL retained earth wall system (1,500 square metre cross-shaped panel) has also been planned for the main river crossing. The Cross Tay Link Road is due to open in early 2025. PROBLEM SOLVED The slender section of the asset BEBO structure blends into the surrounding environment, creating a true green bridge aesthetic. The natural look and feel of concrete are an advantage for the project over a more industrial steel finish. The flat arch also accommodates different typographies within the highway & embankment section. ESG The new road aims to significantly reduce congestion and related pollution in Perth City Centre, and further carbon reductions are expected during the construction phase of the project. As well as providing access to both walkers and cyclists, the structure also reduces the long-term impact of biodiversity loss. EPD certification for our asset BEBO precast concrete arch offers verified carbon data to further support the carbon reduction goals of the project.

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.

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.

COOLE, IRELAND PROJECT OVERVIEW The N17 between Gort and Tuam was opened by the Minister for Transport Shane Ross. The now four-lane highway links Tuam with Gort and progresses on to Shannon airport. PROBLEM SOLVED The clearance profile for the new motorway called for a double span asset BEBO Arch Structure – both inner legs of the arches cut down and resting on a support wall between the roadway lanes. The standard asset BEBO E15.5mT fulfilled all the requirements – a beveled end arrangement completed the layout to fit perfectly into the surrounding environment. ESG asset’s BEBO arches were designed and installed as the first State’s “bat bridge” allowing bats and mammals to cross safely near Lady Gregory’s home of Coole Park. As well as asset's BEBO arches aesthetic design complimenting the surrounding environment, the arches also aim to ensure that the lesser horseshoe bats will use the safe access to Kiltartan cave and feeding grounds in Coole Garryland.

SALTFORD, ENGLAND PROJECT OVERVIEW The Saltford Water Recycling Centre Access Road project included a total of 18 asset MultiPlate corrugated steel buried structures (CSBS). This impressive installation allowed the natural flooding of the river Avon to take place within the ‘Ecological Wetland Scrape’ and lagoons, at Saltford. Asset provided the suitable designed profiles for the chosen contractors to model, which determined the hydraulic performance, and therefore the number of overall culverts required. This project also demonstrates that the end treatment follows the road alignment effectively, and creates a green embankment which allows this series of buried structures to blend into the natural surroundings. PROBLEM SOLVED The project aims to reduce traffic movements and congestion in Saltford village, and provide improved access to the water recycling facility to enable its expansion. The new Saltford Water Recycling Centre Access Road and footbridge over the River Chew (in Keynsham’s Memorial Park), were among 12 selected engineering schemes to go forward to the online vote in the ICE South West People’s Choice Award. ESG The new access road from the A431 at Swineford includes a new bridge over the River Avon, and three new ponds for wildlife. The 18 asset MultiPlate culverts maintain natural flooding of the Avon river without choking it. The ‘Ecological Wetland Scrape’ has been designed to provide a habitat for amphibians, invertebrates, mammals and wetland birds, providing wildlife connectivity within the surrounding area.

TWEEDSMUIR, SCOTLAND PROJECT OVERVIEW This 7m span, 3.56m rise, 21.4m length asset MultiPlate MP200 single radius arch was constructed over a burn at Whitelaw Brae wind farm. Construction of Whitelaw Brae is currently in progress, and is anticipated to be fully commissioned and operational by the end of 2026. Once operational, it will be capable of generating up to 149,400MWh of clean electricity per year (powering around 45,000 average UK homes), and delivering 65,300 tonnes of emissions reductions. We were approached to design and supply a steel culvert over a watercourse, which would provide the main access track to enable turbine foundations as well as transportation of turbine masts, rotors and blades. The asset MultiPlate MP200 culvert is to be backfilled with a road running over the top, in order to facilitate transportation requirements. PROBLEM SOLVED Due to the need for efficient transportation, the burn running through the main access route was the main problem to be solved within this project. Our asset MultiPlate corrugated culvert provided the ideal lightweight solution; a perfect application in remote environments where heavy lifting equipment was not required. Using corrugated steel in culvert and bridge design also offers substantial savings in design cost and installation time. ESG During the planning and installation stages of this project, SEPA (Scottish Environment Protection Agency) were the main consideration due to the protection of the watercourse. SEPA protect, manage and improve Scotland's water environments, which are fundamental for safeguarding biodiversity and ensuring that Scotland’s unique aquatic wildlife is protected. In addition to the watercourse, due to the modular nature of asset MultiPlate, there was minimal disruption to site during installation. This had a positive impact to local wildlife within the area.

GUILDFORD, SURREY PROJECT OVERVIEW 40m of asset BaFix 70 was required as part of ongoing maintenance issues along the Nightingale Road trainline, Guildford. asset were asked to provide a concept to solve a failing masonry retaining/parapet wall issue caused by buddleja growth, which destabilised the retained wall structure. The project was in a difficult to access area, positioned behind a row of terraced houses. The permanent works solution to a 40m section (as instructed by Network Rail) called for our innovative ballast retention system due to reduced installation times whilst backfilling, compared to installing ballast boards. PROBLEM SOLVED The asset BaFix 70 system had to be positioned behind the retained structure, in order for the failing masonry parapet to be removed and rebuilt, and all vegetation removed. Installation was completed over one weekend possession to avoid disruption to train operating companies and passengers, by carrying out work during known hours with no rail activity. ESG The main ESG consideration for this project was social value. Installation noise was kept to a minimum during night working, as asset BaFix doesn't require large machinery to install. The amount of retention achieved meant that no further possessions were required. Re-using existing brickwork also removed the need for further masonry construction to take place, which would have caused disruption to local residents.

SALFORD, GREATER MANCHESTER PROJECT OVERVIEW As part of the Railway Bridge No.7 Reconstruction Scheme, Salford City Council required rehabilitation of an existing bridge deck along with maintenance to the cycle route access and usage. The chosen solution for Railway Bridge No.7 was to reline the underpass utilising asset MultiPlate MP200, with a span of 7.78m, a 4.25m rise, and a length of 110m. Railway Bridge No.7 carries the A580 East Lancashire Road over the disused Eccles, Tyldesley and Wigan railway line based in Salford, Greater Manchester. PROBLEM SOLVED Although the cycle route was temporarily closed during relining, traffic routes were maintained throughout the installation with only intermittent route deviations required during the pumping of foam concrete. As a result of restrengthening the now-redundant existing structure, the asset MultiPlate corrugated solution with a design life of 120 years, now bears the full load of the road above. ESG Deliveries were condensed due to less transportation of material to site, thanks to the lightweight nature of asset MultiPlate corrugated steel. The uninterrupted traffic flowing above the structure also enabled social connectivity along the A580 and beyond. Following successful installation, cyclists were able to use the National Cycle Network Route 55 as originally intended. Through bridge rehabilitation and relining utilising asset MultiPlate, structural integrity was maintained, maximising on-site safety.

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.

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.
