Kingston University update 12 - external escape stair assembly

... and how temporary propping collars are being successfully utilised

Rapid progress is being made with the architectural colonnade structure on the site of the Kingston University Town House project near London.


PCE Ltd worked with Willmott Dixon during the tender phase to develop an offsite fabricated hybrid solution for the concrete frame, the majority of which is exposed and requires a high standard of finish with architectural finished concrete being used for 175 external mullion and spandrel panels and over 300 beams and columns. 


External escape stair

The image (above) shows the offsite engineered precast external escape stairs which have been cast with integral trace heating cabling, which is designed to heat the staircase to prevent formation of snow and ice in cold temperatures. Temporary propping collars are being utilised to avoid the need to drill and fix props into the finished faces of the architectural columns and fins (see below). The majority of the suspended flooring is formed from 229 Double Tees weighing up to 18 tonnes with over 1,300 m² of Hollowcore flooring up to 500mm deep also being used. Other precast unit quantities include 275 columns, 318 beams, 50 solid walls and 52 stair/lift core boxes.
