Project: Green Quarter, Manchester


Client: P.C. Harrington


The contract involved a ground works package,

which included bulk excavations, deep drainage,

concrete works, waterproofing and backfilling to

basement structures.


The schemes involved the following work elements:


● Bulk excavations facilitating the installation of the

   Larson piles and associated struts and props to enable

   the reduced dig to basement level


● The drainage package consisted of both surface water

   and foul systems, which had to be piped from

   basement level and connected into the existing live Systems


● Reduce dig to formation and concrete blind with steel

   Foat finish ready to except waterproof membrane


● Waterproof tanking to external basement walls with

   Fibreboard protection

  

● Back filling operations were the most challenging

   aspect of the groundwork’s package. This was due to

   the width and height restrictions imposed by the Larson

   pile propping system
