Project Overview
This project comprised the upwards extension and full retrofit of a redundant 1980’s office block, giving it a new life as a key building on Aztec West Business Park.
Aztec West 1000 office included a restaurant, café with lakeside views, gym, meeting rooms, co-working space, showers, roof terraces and 230 parking spaces. It has been designed to meet BREEAM Excellent and an EPC A standard, and be powered by renewable energy.
We undertook a structural appraisal of the existing steel-frame building and developed feasibility proposals to increase the gross floor area, thereby enhancing and prolonging the building's design life. This has included consideration of modifications to the existing steel frame structure and assessment of existing load-carrying capacities.
Our structural options considered how to maximise the spare capacity of the existing frame, prior to additional structural modifications and additions being considered. These included an upward extension, lateral extension, significant internal remodelling and demolition, and an entire rebuild.
The project retained the existing steel structure and foundations while adding an extra storey, avoiding demolition. Curtins conducted detailed investigations and applied local strengthening to support the additional load, reducing cost, time, and improving sustainability over a new build.
The Challenge
The existing building was a 2 storey office space and the project's ambition was to deliver a workplace large enough for 850 people. The challenge consisted of keeping the existing steel structure and foundations whilst adding an extra storey, avoiding demolition.
Our Solution
Curtins carried out extensive investigations to both the existing steel structure and foundations to avoid demolition. Local strengthening to steel members and pad foundations was required to support the load from the additional storey. Through this engineering, the existing structure could be retained, which reduced cost, time and improved overall sustainability compared to a new build structure.
