by subcontractors onto the floors. Between 6:00 and 7:00 the crane is allocated to the plastering subcontractor and during the day the crane is used exclusively for the concrete works,” says Ngobese. There are currently 300 people on site and at peak times it will be 400 to 500. The 40 subcontractors working on this bustling site will increase as finishing gains momentum. Ngobese says that time is the biggest risk-factor on this project. “Resources are key. It is a fast track project. We have to ensure that all subcontractors have the resources that they agreed to provide in order for them to work on multiple floors at the same time.” The successful completion of fast track projects relies on having a highly skilled and experienced core team on site that closely manages subcontractors to keep to the construction programme. “In addition, quality is everyone’s responsibility. It may affect our timing if work has to be rectified after it was done,” he says. “These kinds of projects also require constant and in-depth communication with all stakeholders, from the client, professional team to the local authorities,” says Ngobese. Environment and safety Whilst the building is not going to become a green star rated building, Concor, as an environmentally conscious contractor, takes great care to dispose of rubble through one of its subcontractors. “In addition,” says Ngobese, “dust suppression and noise reduction are important.” For such a fast paced site, the safety record of no LTIs is no mean feat. “Safety is paramount for Concor,” Ngobese concludes.
