VALLEY HYPER CENTRE: MULTIPLE CLOSED-FACED RETAINING WALLS
Ideating and implementing innovative solutions to counteract construction space constraints and civil engineering works problems to create multiple close-faced retaining walls that unlock maximum floor space, at minimum cost.
Valley Hyper Centre is a new ±16 700 square metre shopping centre located in Nelspruit (Mbombela), Mpumalanga. As the earthworks for construction of the centre commenced, EIS, in conjunction with Jones & Wagener, was commissioned by Endecon Ubuntu Engineering Consultants to design and build three retaining walls along the perimeter of the development, to prevent environmental soil from encroaching on the development and retain optimal usable floor space.
One of the major challenges at this site was that it had excessive groundwater, to such a degree that up to 18,000 litres of water were drained daily during the earthworks phase, with no signs of submission.
Another key issue was that there was extremely limited space to work in whilst building the retaining walls, due to an existing road along the top side of the retaining wall and the building of the new shopping centre in front of the walls.
