One Sherwood Street is a major mixed-use development on one of London’s busiest thoroughfares. The architectural concept for the building includes a feature roof comprising a series of geometrically varying triangles and quadrilaterals which intersect at differing angles and pitches.
Challenges
Originally designed as a traditionally built, hot-rolled steel roof with individual infill members, the complexity of the design and detailing and site constraints required an alternative approach to construction. The off-site, modular approach allowed the roof to be prefabricated as a series of steel panels that could be assembled in a controlled factory environment.
Using Tekla software
The detailed modelling of steelwork, including packing plates, bolt assemblies, and other finer details, enabled the roof structure to be designed with construction in mind. Clash detection reviews and coordination within the federated 3D model ensured that site installation and tolerance issues were addressed early on, mitigating potential delays and rework. Additionally, the lifting strategy, an integral part of the modular design, was developed using the 3D BIM model.
