Summerhill Drive

Location:  Somerset West

Value: R 22,7m

This project was negotiated with The Collins Group(The Client) and Lazercor(Project Manager) and commenced in August 2018. It forms part of the bigger MZURI Development, situated between Sir Lowry’s Pass Road, and Bizweni Avenue, Somerset West. The value of the project amounted to R22.7m and was completed within the 8-month contractual period, and within budget. The Consulting Engineers were ICE Group and Ingerop.
The scope of work was to relocate an existing detention dam which was situated on the site, to allow for the construction of Summerhill Drive Road, which provides the main access to the Estate.
The main challenge was to relocate the dam in the middle of winter while maintaining the flow throughout the process. We managed to design a diversion, which allowed us to breach the existing wall and relocate to its final position. The infrastructure in the dam included stormwater pipes ranging up to 1050mm at the outlet, and a subsurface drainage system to direct low flow stormwater into the outlet system.
Once the construction of the dam wall had been completed, we could commence with the earthworks and services for the main road, as well as the widening of 3 slip lanes on the Sir Lowry’s Pass/Union Drive Intersection.
The traffic signaling at the intersection has been upgraded to allow for the additional entrance to the Estate.
The dam wall was constructed using 370m³ of gabions, 3700m³ of imported structural fill, and on-site fill material of 3000m³.
