Esor cracks dolomites for Gautrain in Centurion

摘要

Leading Geotechnical solutions company Esor, part of the JSE-listed Esorfranki group, recently completed the excavation of Gautrain pier foundations consisting of six 7-m-diameter shafts at depths ranging from 21 to 29 m. The Centurion contract, awarded to Esor by Bombela Civils Joint Venture (CJV), was valued at approximately R34 million.rnAccording to Esor senior contracts manager Anton Naude, the main challenges of the contract were the dolomitic conditions, the necessity of blasting in a built-up area close to busy offices and the presence of ground water as three of the six shafts are founded below the water table.
