RIVER STREET TOWER

River Street Tower, Manchester is a £110 million development located between River Street and Garwood Street, next to the Mancunian Way. The scheme encompasses 791 student bedrooms within a 32-storey building and includes a mix of studios, cluster bedrooms and apartments as well as resident amenity spaces. Designed by award winning architects Simpson Haugh and Partners, the project brings high quality, affordable student accommodation to Manchester.
The building’s innovative design is arranged in three distinct blocks forming a U-shape around a roof garden on top of the ground floor. The scheme creates a visually striking development which delivers outstanding accommodation for students at the heart of this vibrant new community.

DESIGN & VISION

The building’s architectural composition relates to the city and local context, set at a scale comparable to the surroundings. The outer elevations comprise a combination of Cor-Ten weathered steel rainscreen cladding panels, providing a contextual material relationship with the surrounding built environment. In contrast, the inner courtyard elevations comprise a combination of coloured dark-blue back-painted glass rain-screens and dark-blue metal panels, creating a layered, reflective sequence of surfaces. This development regenerates a previously dilapidated brownfield site, providing much needed accommodation for the increasing student population.

CONSTRUCTION

The composition of the three simple, bold volumes expresses the modular nature of the accommodation, stepping from a ten-storey section fronting Garwood Street, down to five storey section facing River Street, together with a 32-storey tower.

The construction solution for River Street comprises a main frame concrete structure with infill panels. The offsite manufactured Pre Assembled Frames (PAF) were pre-boarded and insulated in EOS’s quality-controlled factory conditions using light steel frames from EOS and Weather Defence boarding from siniat as part of an Etex package, which is an A1 non combustible product.

EOS is dedicated to promoting sustainability at every stage of the construction journey – our steel is highly recyclable, providing little onsite waste. Manufacturing a high performance, airtight building envelope reduces carbon emissions and energy requirements for the lifetime of the building. By lowering deliveries to site through taking an offsite manufacturing approach, reduces carbon emissions from vehicles and minimises disruption to the local area.

EOS INVOLVEMENT

The prefabrication of the individual steel elements took place under controlled, highly regulated and safe factory conditions. Using leading edge systems, the EOS team delivered precision-engineered components. With so much work carried out offsite, the onsite construction schedule was reduced, and the build programme was relatively unaffected by adverse weather conditions.

All pre-assembled framing (PAF) systems were pre-panelised complete with boarding and insulation as part of the offsite manufacturing process – reducing the need for working at height. No cutting or hot works were required onsite for the pre-assembled frames which improved site safety.

Once the frames were designed using our 3D Tekla modelling software, they were directly uploaded to the roll-forming machines, using a bespoke CAD/CAM interface, where they were produced to exact dimensions using CNC technology. Each stud is identified with an inkjet printer to match the assembly drawing and every frame has an identification label attached. This details the project, frame number, order number and site location on the GA site drawings so they can
be positioned quickly to their onsite location.

All elements were rolled directly from the BIM model ensuring quality and requiring no cutting or reworking onsite. Pre-assembly means that offsite manufactured elements are made ready to ship to site ahead of programme and can be exposed to elements for 12 months prior to final finishes being applied.

All products were manufactured under strict quality management systems fully compliant with BS EN ISO 9001:2018. Our accredited quality management systems and procedures eradicate onsite variability and ensure lifetime ‘in service’ performance and durability.
