PROJECT CHALLENGES The existing plant at this site ultimately required substantial repairs ( a few hundred thousand Rands in reality ) and so the recommendation of replacement was a better end result . Had repairs been undertaken , it would have been a case of throwing good money after bad in VMG ’ s view .
From the quoting phase already , everyone was under pressure and was required to work under short timelines . Part of the process was getting contractor quotes from local companies ; however local suppliers could not be utilised as their pricing was substantially more than quotes from companies based in Gauteng . The contracting was awarded to Elmecair for this reason and because VMG had worked with the team on a prior project . When the green light was given , teams would also need to be on site the very next day .
