14 August 2014 - Consulting Engineers South Africa (CESA) annually celebrates “innovation, quality, outstanding workmanship and professionalism in engineering” through the CESA Aon Engineering Excellence Awards.
This year, Aurecon entered three projects into these awards:
The prestigious awards function was held on 12 August at Vodaworld, Midrand and aimed to showcase the important role that infrastructure plays in the sustainable development of our country.
Malmesbury WWTW and KwaMashu Interchange won the top accolade at the awards in their respective categories, while Grundfos offices and warehouse received a coveted commendation.
The Malmesbury Wastewater Treatment Works (WWTW) treats wastewater from Malmesbury, a rapidly growing town to the north-east of Cape Town. The original WWTW was overloaded and discharged substandard effluent into the nearby Diep River, exacerbated by periodic sludge spillages. The Department of Water Affairs withheld consent for new developments in this municipal area until the problem was resolved.
Aurecon proposed an innovative solution using a membrane bioreactor (MBR) and designed an ingenious hybrid system, incorporating the existing treatment works. The hybrid system made the use of MBR technology viable from a cost perspective and allowed the responsible operator, the Swartland Municipality, to reuse the full dry weather flow.
The pioneering conversion of the standard diamond KwaMashu interchange to an innovative diverging diamond layout has provided a low cost, effective means to enhance interchange capacity and safety. It is the first application of a diverging diamond interchange (DDI) in the southern hemisphere.
The original KwaMashu interchange carried high volumes of traffic in all directions, resulting in extreme congestion throughout the day, with queue back-up extending onto the N2 northbound carriageway for several kilometres.
The pioneering introduction of the DDI concept for the KwaMashu interchange upgrade was successfully commissioned in June 2013. It has improved capacity on the interchange and significantly reduced traffic and pedestrian conflict points, with a consequent reduction in accidents and a complete elimination of right-angled accidents.
Growthpoint Properties was appointed to develop state-of-the-art offices and a high-tech warehouse for Grundfos, one of the world's leading pump manufacturers.
The challenging slope of the site was cleverly used to accommodate parking underneath the building, as well as an innovative storm water attenuation facility. The sophisticated ESD included a rainwater harvesting system incorporating Grundfos' own customised plant for purifying a portion of the rainwater to drinking water quality. This is believed to be a first in South Africa.
The office building has been awarded a 5-Star Green Star SA Office Design v1 rating and is the first integrated office and industrial facility to be awarded a 5-Star Green Star SA Office Design v1 rating by the GBCSA.
"We are extremely proud to have been involved in these three stellar projects and privileged to be able to partner with valued clients and project teams. It is extremely gratifying that our innovative solutions for our clients have been honoured at the highest level with the achievement of these awards," comments Albert Geldenhuys, Aurecon’s Managing Director, South Africa.
