Civil Engineering March 2021 29 Q Q 250 mm FabPanel sections. Q Q 50 MPa concrete mix. Q Q 8 × 12.7 mm bottom and 2 × 9.53 mm top prestressing stands. Q Q Panels cast in their slipformer imported from Brazil, with strands tensioned to 70% GUTS of 1 860 MPa, and de- tensioned at 35 MPa concrete strength. Some time after the project commencement, KES decided to renovate and add onto the entertainment area within the original northern entrance building. Part of this work involved the removal of a sheeted roof and addition of a flat concrete roof. To limit the additional load on the original brick walls and founda- tions, and to aid construction time, CSS supplied a 50 m 2 rib and block slab using their S150 block and 50 mm thick topping. The rib and blocks were installed in March 2020 prior to the Covid-19 lockdown and the topping was cast in May 2020 once the site had been cleared for construction to re-commence. All other concrete works were constructed by Akhane Construction, including the main entrance special smooth double storey frame and exposed aggregate arena seating. The project was completed in December 2020 and is due to be officially opened by the school in early 2021. IN CONCLUSION The KES Aquatic Centre proved that upfront collaborative design engagement can result in a combined architectural and structural engineering solution that not only compliments the original intent of the architect’s design but enhances it. The early-stage emphasis on thorough design enabled the main con- tractor to price the works accurately and plan the critical tasks together with the design team to ensure that the design could be constructed as envisaged to the required level of accuracy and quality. The project required a true team effort – fitting for a facility that will foster teamwork and excellence in swimming and wa- terpolo, and perhaps inspire some to consider a career within the built environment.  PROJECT TEAM Client King Edward VII School Project manager & architect Shed Design + Architecture Civil & structural engineer WCSE, in collaboration with The Structural Workshop Quantity surveyor Jan Pienaar & Associates Pool specialists Water Dimensions International Main contractor Akhane Construction Ready-mix supplier Metier Mixed Concrete Piling subcontractor Pilecon Specialist formwork Form-Scaff Heavy duty anchor supplier Peikko South Africa Precast and rib & block supplier Concrete Slab Supplies Waterproofing additive Penetron SA Steel fabricator Tass Engineering Sheeting supplier GRS A STRONG FOUNDATION FOR INFRASTRUCTURE SUCCESS ROCLA is South Africa’s leading manufacturer of pre-cast concrete products.
