Project: Breton Eagle CNC Foundation
Address: Tingalpa QLD

Overview:

This project involved the construction of two in-ground machine footings to support Breton Eagle E1 1000 CNC machines within an operational facility. The scope required precise demolition of existing slabs, bulk excavation, and complete footing construction. By working closely with the client, Kraftur® was able to deliver A Concrete Advantage® with exceptional quality and efficiency, completing the project at their Tingalpa warehouse ahead of schedule.

Scope of works:

  • Full survey and set out
  • Surgical demolition of existing warehouse floors to minimise dust and vibration
  • Bulk excavation of existing ground and removal of spoil from site
  • Supply and install 40 tonnes of reinforcing steel for both footings
  • Formwork setup and installation for pits and trenches, including supply and install of galvanised protection angles
  • Formwork to pockets for machine connection
  • Full concrete supply, place and finish to both footings
  • Both footings completed in three major pour sections due to 1.9 m overall depth
  • Concrete Pumping in confined work spaces

Challenges Faced & Solutions:

One of the primary challenges of this project was the restricted access to the work area within an active facility. With only a single roller door available in a 24-hour operating zone, and personnel, finished products, and racking blocking large vehicle access, careful planning was required. To address this, all material deliveries were scheduled with a maximum 6-meter crane truck, the largest vehicle able to navigate the limited space. Reinforcement bars were also cut to 6-meter lengths to fit these smaller trucks, ensuring efficient delivery and unloading directly at the work site. Spotters were deployed for all vehicular movements, including delivery trucks, tip trucks, and excavators, to maintain safety in the confined area.

Another significant challenge was demolishing existing slabs within the warehouse without generating vibration or dust, which could disrupt ongoing operations. To overcome this, Kraftur® employed a precise approach, cutting the slabs into smaller blocks and using a forklift equipped with a custom Kraftur® concrete lifting frame to remove and place each block into disposal bins. This method minimised dust and eliminated vibrations by avoiding the use of large jackhammers typically used in demolition, ensuring minimal disruption to the facility's activities.
