KEY PROJECT FACTS

• By completion, Concor Infrastructure’s rehabilitation on this section of the R75 will have involved 15 000 cubic metres of fill, from both commercial sources and from bulk excavations on site. • A cement-stabilised sub-base layer – amounting to 56 000 cubic metres in volume – was applied to sections of the road, consuming 2 600 tonnes of AfriSam Roadstab. For the surfacing, about 93 000 tonnes of asphalt is being supplied by a Port Elizabeth-based supplier. • Some 16 000 cubic metres of concrete will be used by the end of the project, for installations including 17 linear kilometres of concrete sidewalks and 7 kilometres of concrete-lined drains in the median. The project also involves 4,4 km of subsoil drains and 4,4 km of concrete lined side drains. • As an important part of the safety-enhancing features of the work, there will be 45 kilometres of guardrails and 18 kilometres of anti-climb fencing along the route. • Concor Infrastructure’s commitment to safety is reflected by the achievement of 550 000 Lost Time Injury Free (LTIF) hours by the end of September 2018. High quality work is ensured by close monitoring and supervision, carried out through daily inspections and weekly audits. This has led to consistent client audit results on site of between 96 and 98%. • Ongoing skills development includes the opportunity for 10 civil engineering students to gain work experience on site, benefiting from the mentorship of Concor Infrastructure engineers while undergoing experiential learning in fields such as construction management and survey.
