How do you approach the health and safety of you workforce? GeoCiv’s SHEM System is an integrated system which incorporates Health, Safety, Environment, Risk and Quality. The system is designed and implemented to reduce non conformances and promotes a safe work environment for all employees, contractors and visitors. Keystone Park in KwaZulu-Natal GeoCiv was appointed to assist in the design and supply of a soil improvement project to assist in stabilising a filled platform with settlement issues. The difficulty and risk for the execution and design of this project lay in the stringent settlement criteria after the completion of the works. GeoCiv’s scope included the installation of roughly 5 300 rigid inclusions to depths of -30 m to counteract the settlement of the earth platform as constructed for the warehouse. The nature of the fill materials used for the platform and high loading on the floors for the warehouse created complex and various design criteria for the different areas within the warehouse. During the installation, large, voided areas within the fill required massive amounts of grouted void filling, collapse and redrilling to complete the proposed remedial works. Certain areas of the warehouse required limited How do you ensure the quality of your execution?

access methods and specialist equipment to complete the installation. The completed crew required to complete GeoCiv’s scope, numbered in the range of 50 for a duration of eight 8months. Up to 50% of the labour used was procured from the local community. This project was awarded in May 2022 and was completed in December 2022 The Teraco Data Centre – CT2.2 This project entails phase 2 of the Teraco Data Centres under construction on Brakenfell Cape Town. GeoCiv was appointed to complete the piled foundations for this as well as the previous phase of construction. At the time of award, it was the largest CFA piling project in South Africa. This project scope included the design and supply of CFA piles for the concrete structure. Piles required for this project ranged from 750 mm diameter to 900 mm diameter piles to depths of between 16 – 18 m in saturated sands. A total of 850 piles were required for the project. The saturated soil conditions of the area and heavy loading of the structure made use of large diameter CFA piles that needed to be installed to deep lengths to cater for these loads. strict timelines also meant the piling works required upwards of 130 m 3 of concrete supply for the duration of the project, each and every day. Two piling teams were required for this installation. Piling crews require a team compliment of seven per rig to complete such a scope of works. This project was awarded in March 2023 and was completed in June 2023.  works. Certain areas of the warehouse required limited access methods and specialist equipment to complete the installation.
