Double-header for Concor In SA Best Projects Awards

09 November 2017

Concor has made a great showing in the 17th annual Construction World Best Projects competition, showcasing excellence in the South African building and civil engineering sectors.

Experienced members of the construction fraternity judge the awards, which are hosted by Crown Publications, the publishers of Construction World magazine. There are six categories available for project entries, and they are judged according to a range of criteria that include construction innovation technology, design, cost, quality, risk management, health, safety, corporate social investment and environmental impact.

In the Building Contractors category, Concor Buildings won the top award for its Menlyn Shopping Centre project; and in the Civil Engineering Contractors category, Concor Infrastructure received a ‘highly commended’ award.

Menlyn Shopping Centre

Winning the Construction World’s Best Project award in the Building Contractors category is a huge accolade for Concor Buildings, especially given the scale and complexity of this contract. In a R2,2 billion extension and refurbishment, this project has made Menlyn Park Shopping Centre in Pretoria the ‘biggest shopping experience’ in Africa. 

A remarkable aspect of this job was that tenants and shoppers still had access to the existing mall areas so there could be business as usual. This meant that many of the teams worked at night, so that tasks were done before the mall opened each day at 08h00.

The project even received a Green Building 4 Star rating for its environmental and sustainability considerations – a ‘first’ for the retail sector in South Africa.

Loeriesfontein and Khobab Wind Farms

In the Civil Engineering Contractors category Concor Infrastructure was highly commended for two pioneering renewable energy projects in the Northern Cape: the Loeriesfontein Wind Farm and the Khobab Wind Farm.

In a consortium with CONCO, Concor Infrastructure was responsible for the construction of all 122 wind turbine generator foundations, as well as the adjoining hard stands and internal roads on both sites. Each of the wind turbine bases is 19 metres in diameter, and holds a 99 metre high turbine tower with an 80 tonne nacelle.

The plinths at Loeriesfontein were constructed using high-strength 60 MPa concrete with a design mix of 75% ground granulated corex slag (GGCS) in place of cement. Concor Infrastructure used 50% waste material for both the plinth concrete and the 30 MPa conical base concrete. This helped reduce the project’s estimated overall carbon footprint by 31%.

In line with Concor Infrastructure’s skills development strategy, these remote projects managed to source and train much of their workforce from the Loeriesfontein community 60 km away.

Situated in such an arid area, the project conserved water through re-use and re-treatment, using a screening system to remove the heaviest solids and bacteriological rollers for the remainder. Many environmental issues were addressed, including protecting and trans locating threatened and endangered plant species, and reclaiming contaminated soil through bioremediation.

Safety was always a high priority, allowing the project to achieve two million Lost Time Incident Free (LTIF) hours in August 2017.
