These works were part of a scheme to reconstruct a defective rapid exit taxiway linking the main November taxiway to the Southern runway.
Working for Morgan Sindall, TAG construction were employed to carry out the following works as a sub contract package where TAG were responsible for the management and supervision of all works, deliveries, muck away, transportation of operatives and logistics airside to carry out the works below.
Replace 56no PQ Concrete bays. This involved saw cutting and removal of 56no bays where the concrete was taken off site for recycling. The bays had to be cleaned out, repaired using a high spec pre mixed mortar and re-screeded to provide a flat suitable consistent surface for placing the new bays.
Replace the bays pouring and finishing 900m3 of new F6 PQ Concrete to the specific airside specification.
The second part of the scheme was to reconstruct a Rapid Exit Taxiway link. These works involved trimming and compacting the type 1 sub base ready for the concrete pavement. Installation of specific profiled formwork. Pouring 1500m3 of new reinforced PQ concrete pavement over 20no 30mtr x 6mtr bays.
TAG also carried out the reinstatement of the taxiway drainage which included pre-casting 3no new concrete drainage F900 catch pits, installing these catch pits on site and connecting them to the existing drainage carrier drains. TAG Also had to construct a new reinforced concrete base and lay new F900 clearway slot channels with a concrete surround to the taxiway.
These works were carried out over nights and days.
Throughout the duration of the scheme TAG also supplied labour to the main site including specifically training airside taxiway crossing controllers.
