REMOTE CONTROL demolition robots have been critical to the tricky dismantling of the 106m high Torre Windsor, demolition contractor Ortiz project manager JosÚ Luis Cano said last month.
The upper stories of the fireravaged structure were judged too dangerous for workmen to enter, so operations could only be carried out from cranesuspended cradles.
Instead, remote control hydrodemolition robots and remotely controlled excavators fitted with concrete 'nibblers' were lifted onto the suspect floors and controlled from the cradles.
Four giant crawler cranes with booms up to 140m high have been deployed on the site.
Cano said that extensive propping had to be carried out in the underground car parks to allow the cranes to get into position.
No final decision had been taken on the future of the Torre Windsor when NCE visited the site. Ortiz is programmed to stop operations at the massive transfer structure formed by the two 'technical floors' at the third and fourth levels, which have suffered no serious structural damage.
This would leave Torre Windsor owner Ason the option of building up again off the same foundations, significantly reducing reconstruction costs.
