Gauteng Provincial Road P36/1: Rehabilitation of sinkhole (Km 33) on the R50 road between Pretoria and Delmas Sinkhole

CLIENT: Gauteng Department of Roads and Transport (GDRT)

LOCATION: Pretoria, South Africa

Services Provided:

  • Sinkhole rehabilitation implementation
  • Design of road pavement and stormwater management
  • Prepare contract documentation
  • Site Supervision

Project Scope:

The rehabilitation design implementation of a sinkhole, preparing contract documentation, and providing site supervision for the repair of Provincial road P36/1 (R50 Pretoria to Delmas) due to a sinkhole along the road. The sinkhole, over an area of about 300m x 35m, had been present for some time, but it was reactivated after heavy rainstorms, leading to the closure of the road in October 2019. The primary objective of our appointment is to reinstate the pavement layers after the completion of the construction work in rehabilitating the sinkhole. The sinkhole rehabilitation design does not form part of our scope and was done by leading Geotechnical Engineering experts. The road was closed due to the high risk for the development of a sinkhole, which caused mayor traffic disruptions.

Features:

  • Implement the rehabilitation measures and design to rectify the existing sinkhole in the road reserve
  • Accommodation of traffic
  • Stormwater management
  • Soil improvement
  • Site supervision

Project Value: R 50 million (Est).

Fee Value: R 6 million.
