What is the purpose of the structure/ project?
The structure serves as a retail centre.
What was the brief to the architect?
To maximize space utilization and minimize construction time.
Give a brief description of the structural framing. What type of sections were used (e.g. hollow, cellular, I beams etc) and why?
The main roof structure consists of girders and castellated rafters. Castellated beams were used for aesthetics and to reduce the overall weight of the sections along the span. Also to increase the spanning capabilities.CHS were used in the barrel vaults as an architectural feature.
Were there any challenges in the fabrication of the project from the engineer’s design – if yes, please tell? Tell more about fabrication and erection process if it was complex, difficult, innovative etc.
The fabrication of the barrel vault needed to be completed to a tight tolerance in order to ensure correct fitment of barrel vault sky –lights.
It was complex due to the fast-track nature of the project. Whereby close coordination was required between the civil contractor, steel contractor, building contractor, sheeting contractor, fire services, mechanical services in order for the works to be completed in the required sequence within the building footprint.
What is special/ unusual/ innovative/ aesthetic about the steelwork/cladding in this project?
The structural steel barrel vault arches on Makro structures have become a nationwide symbol of the Makro brand.
How did the project team work together (e.g contractor involved early, challenges/ ease of communication etc.)
MPW detailing office worked in close communication with the engineering and architecture team in order to ensure discrepancies were picked up within the detailing phase, to allow for adjustments to be made prior to fabrication. This resulted in a structural system which very closely resembled a Mecano set. Therefore it allowed us to reduce erection time on site. All contractors on site worked in close unison moving from section to section ensuring all the requirements were met timeously.
