Restricted-access piling

Piling around existing buildings, tight boundaries and limited working room.

The available working space affects equipment selection, pile installation and the order of work. The following projects show how The Heavies have coordinated piling in constrained locations.

The Heavies installing piles inside the retained King Street building in Newcastle

King Street, Newcastle

Foundation piles and shoring within a retained structure.

The site

Existing slabs and services restricted access. Old concrete and brick footings complicated drilling.

Our approach

Worked with Hunter Group’s site team and tight-access equipment to install foundation piles, contiguous wall piles and sheet piling.

Developer: Hunter Group. Engineer: Northrop.

Contiguous piled retaining wall installation on the narrow Newcastle East site

Murray Avenue, Newcastle East

A staged retaining wall package on a site under 6 m wide.

The site

A site less than 6 m wide, steep ground, shallow neighbouring foundations and hard rock constrained access and construction.

Our approach

Sequenced the walls and foundation piles, coordinated excavator positions, used a masted rig where access allowed and formed a ramp for the lowest stage.

Builder: GTS Constructions. Engineer: Izzat Consulting Engineers. Architect: Curious Practice.

Plan the access before the rig arrives.

Working room, overhead clearance, existing services and the working platform all affect the installation sequence. The King Street and Murray Avenue projects show how those constraints shaped the work.
