Riverside House is set to become a four-storey office block close to Manchester’s city centre. Brick, glass and architectural concrete have been carefully combined to achieve a balance between old and new.
Bardsley Construction is delivering the scheme, with sub-contractor BIAD Civils overseeing the concrete work.
We were appointed to provide formwork for all vertical structures. This included architectural walls for the core. In addition, safe and reliable temporary works had to support the concrete canopy, which cantilevers out around the east, west and south of the building above the fourth floor.
“With PERI’s support, we have managed to achieve the specified architectural finish hand in hand with their designers. The VARIO system is easy to use, and the technical support that have been behind us have been excellent.”
For the architectural walls, we used VARIO formwork as the arrangement of girders and ties made it possible to achieve a regular tie pattern and create the desired blemish-free surface.
To alleviate on-site operations for the customer, our fabrication team produced mitre joints on over 100 inner plywood skins to achieve accurate right-angled corners. The mitre joints offered a smoother finish compared to stripping pieces on this project, which would typically be used to assist formwork removal.
On the core, the external formwork was supported via CB 240 climbing platforms, whilst a BR shaft platform supported formwork inside the lift core. Through careful design and planning, we positioned climbing anchors between slab and finished floor levels to avoid being visible on the surface of the concrete.
For the canopy, we worked with structural analysis software to assess the buildability of the support structure and ensure the solution was safe for site operatives. We used RS Props with MULTIPROP shoring arrangement to
provide lateral restraint, ensuring the canopy was secure until the concrete gained sufficient strength.
