The city of London's latest landmark tower 51 Lime Street is approaching topping out after a rapid construction programme saw each floor of the 29 storey, 125m tall building erected in four days.
Speaking at NCE's tall buildings conference last week Whitby Bird associate director Peter Chipchase said the quick construction was down to use of 'jump forming' platforms which made it quicker to 'hang up' the formwork for the walls of the building.'Once we got it up and running it's a very quick process,' he said.Chipchase also pointed to the use of fire protected pre-cast concrete elements, such as edge beams, that were lifted into place, keeping insitu casting to a minimum.'With the savings it gave us in the programme it ended up being the best solution,' he said.The choice of a concrete core for the building aids speed of construction, added Chipchase. The project is due to complete early next year.
