10 July 2018. It was a night to remember for Royal HaskoningDHV at the SAICE JHB Regional Awards held in Midrand on Thursday 5 July 2018. The Level 1 B-BBEE engineering consultancy walked away with 4 awards for the Grayston Pedestrian Bridge at the gala dinner. The bridge was awarded the Most Outstanding Civil Engineering Achievement – Community Based Category. It was also awarded the Most Outstanding Project in each SAICE Division – Transport Engineering Category. It came 2nd in the Most Outstanding Civil Engineering Achievement – Technical Excellence Category. It came 3rd in the Most Outstanding Project in each SAICE Division – Structural Engineering Category.
The Grayston Pedestrian Bridge forms part of a pedestrian and cycling corridor built to connect residents of Alexandra Township to Sandton in Johannesburg. Alexandra is one of the poorest urban areas in South Africa whilst Sandton is one of the most affluent. Previously separated by vehicle-centric infrastructure, the “Great Walk” project includes integrated bus rapid transit systems and provides unobstructed daily movement for the 10,000 people who make that journey via a 6m wide sidewalk and bicycle lane with a 289m long cable-stayed pedestrian bridge over the busy M1 freeway at Grayston Interchange.
The project, commissioned by the Johannesburg Development Agency, an agency of the City of Johannesburg, was envisaged as a community focused project incorporating sustainable best-practices such as local labour and design approaches intended to minimise future maintenance needs. While the project has achieved the original design goals, there were many challenges. These required the project team to identify innovative solutions during construction without impacting the final cost.
