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
