Ramboll provided civil and structural engineering design services for the first building to be completed under the Paradise development, responsible for the design from RIBA Stage 4 to project completion.
Designed by Eric Parry Architects, the building is now fully occupied by professional services firm PwC, who opened their largest UK regional office at One Chamberlain Square in 2019.
Situated on the site of the old Birmingham Library and constructed on a Ramboll designed podium structure, One Chamberlain Square provides retail outlet space at ground level, seven storeys of office accommodation and a plant enclosure situated at roof level servicing the whole building.
Our engineers developed and fully detailed a highly efficient post-tensioned concrete structural design, including a complex transfer structure at Level 6. Working in close collaboration with our construction partners, Ramboll introduced major changes to the concept design for the building structure which halved the number of subcontractors required to complete the structural frame, generating significant cost and programme savings for the project.
The intricate facade arrangement, including an array of ceramic fins springing from an exposed polished precast concrete frame, required Ramboll’s engineers to work in close collaboration with the architect and specialist facade designers to produce and coordinate the complex facade support systems required to successfully realise the architectural ambition for the building.
Ramboll’s structural engineers were also instrumental in the design of the office and retail unit fit-out works.
