Jet Demolition beat seven other bidders to demolish two cooling towers at the former Athlone Power Station at a cost of a little over R6-million (Approx. $766,560 US) to the city.

Clive Justus, the City of Cape Town's mayoral committee member for utility services, said the eight bids ranged from R4,79m (Approx $611,970 US ) to R23,46m (Approx $2,997,250 US).

"Following an evaluation and a check for compliance with the tender requirements, the lowest offer which complied with the specification - R6,496m (Approx $829,929 US)was submitted by Jet Demolition (Pty) Ltd," said Justus.

In terms of the bid specification and an agreed working program, the winning contractor will be responsible for safe access to the towers and their implosion. Thereafter, they must clean up, level and prepare the site for subsequent operations.

Three months ago reinforced concrete stiffening rings on one of the towers collapsed.

"These stabilizing rings were added more than two decades ago and (its) collapse raised safety concerns. Two consulting engineering companies confirmed that the towers may collapse, particularly in strong, north-westerly winds and a decision was thus taken to proceed with the demolition of the towers," said Justus.

"The need to expedite the demolition was obvious and the city manager's office accordingly awarded the contract. The company's track record indicates that it will be able to successfully complete the contract."
