St Giles is set to be an internationally recognised destination for commerce, culture, creativity, and inspiration, set in the heart of London next to the newly expanded Tottenham Court Road Station.
Delivering Q4 2021, this mixed-use creative quarter will fuse events, hospitality, information, retail, workplace, and leisure. Inside the various buildings there will be a mix of uses, including a flexible urban gallery, including 360-degree 8K floor-to-ceiling screens showcasing an ever-changing programme of events, news, products, art, and an ongoing information stream.
There will also be two events venues, residential units, a hotel, office space, restaurants, bars, and retail shops. That amounts to over 240,000 sqft of space.
Orms BIM deliverables on St Giles Circus
With a world first innovation brief and complex site constraints to contend with, Orms, the wider design team and Skanska, the main contractor, developed BIM models to aid costing, coordination and 4D sequencing. Key to this success was the collaboration with other consultants and sub-contractors in an interactive 3D environment.
BIM was a real asset in delivering all tender and construction information. This included drawings, schedules, specifications, and quick and effective visualisations achieved by rendering BIM models directly.
Industry standard Uniclass information was provided for all model objects and to successfully share the individual models a Common Data Environment was in use throughout construction stage.
Another benefit of the BIM process was being able to take survey information during construction and quickly compare as built conditions against the design intent BIM models. This approach identified deviations and non-conformities in 3D, allowed to spot issues early, understand potential implications and decide on the best way forward – a true real time benefit to the contractor and the client.

Managing and tracking issues
In an ever more complex world Orms actively encourage the full use of BIM to support client’s aspirations, reduce risk on site and develop digital twins to support post occupancy needs of the clients and building management teams.
On St Giles Circus project use of BIM delivered multiple benefits to the client, design team and contractor.
“By the end of the project, we had 130 individual models from our supply chain and consultants. The construction team addressed vast number of issues and clashes before getting to site, enabling less risk to installation, buildability, less unnecessary hot works on site and less rework.
Identifying and handling issues with an ever-growing list of models was a tricky task. BIMCollab, a cloud-based issue tracker allowed Skanska to digitally track issues, provide reports and manage issues ahead of fabrication, installation, and pre-planning. Using this tool encouraged the design team to collaboratively communicate and resolve issues before they were raised in the design team meetings, thus freeing up time for more complex issues to be discussed.
Tracking and managing the design digitally is vitally important in assisting the design teams during delivery, providing early insight on technical challenges but also saving time resolving the challenges.
We had good engagement from both the supply chain and consultants, which allowed for issues to be resolved in a timely manner.”
