An early delivery for steel detailing
Advance Steel and BIM collaboration help steel fabricator deliver a hospital’s new maternity unit on time
Kettering General Hospital in Northamptonshire, England completely replaced its old maternity and gynecology units with a new UK£4.5 million expansion and renovation. The project included two new obstetrics/gynecology operating rooms and supporting accommodations constructed in a compact new extension to the front of an existing wing of the hospital. The project also involved remodeling the existing operating rooms to provide modern recovery and support spaces. Steel fabricator TSI Structures provided steel connection design, detailing, fabrication, and erection for the new expansion.
The hospital’s existing maternity operating rooms and facilities had become outdated and were causing inefficiencies in services. As such, the hospital was eager for the project to be delivered and the new facilities operational. “We had an aggressive schedule for our drawings and steel works,” explains Adrian Betts, TSI’s drawing office manager. “Adding to our schedule challenge was the requirement that we provide full connection design to the new Eurocode 3 building code that is gradually replacing an existing British Standard code.” Many steel connection design software products do not yet include support for Eurocode 3.
In addition, the extended project team (including TSI, the general contractor Interserve, and BWB Consulting for structural engineering) were required to use some of the collaborative Building Information Modeling (BIM) practices that will soon be mandated for all U.K. government public projects, including the sharing of model-based project data amongst the project team.
TSI used Autodesk® Advance Steel software for its steel connection design, detailing, and fabrication on this project. “The bidirectional link between Advance Steel and Autodesk® Revit software—used by BWB’s structural engineers—made it easier to reuse their design model and work more efficiently with their engineers using a BIM workflow,” says Betts. “Due to this link, as well as the accuracy and detail of BWB’s model, we did not have to waste time recreating the steel model in Advance Steel and could immediately start adding our steel connections.” TSI used Advance Steel’s built-in steel connection design engine (which fully supports the Eurocode 3 building code) to check connections in real time. Furthermore, the Advance Steel model was used to automatically generate CNC data for TSI’s fabrication processes.
The Advance Steel software’s ease of use, speed of modeling and connection design, and integrated design checks on the fly—combined with the ability to reuse the structural engineer’s Revit model—helped us reduce our anticipated schedule time by approximately 20 percent.
