The construction of the new AEGIS Aged Care Development in North Coogee is progressing well and we have just reached another major milestone.
The first area of formwork to level 1 (the second suspended level) is installed in readiness for the first level 1 concrete pour. We are installing the load bearing brickwork in conjunction with the slab formwork.
The suspended ground floor slab concrete pours are now nearly complete with each of the staged pours being around 250 cubic meters of concrete so each of these events has demanded extensive prior planning and preparation.
One of the most important requirements prior to concreting the suspended ground floor slab areas was the correct installation of the vibration isolation pads. These are installed on top of the basement columns and under the soffit of the suspended slab areas.
This structure is unique in that vibration isolation has been incorporated into the engineering design effectively separating the superstructure from the sub structure. This is to ensure that no vibration is felt from nearby rail freight which passes close by to the western side of the development. The rubber pads (or bearings) that are used for the vibration isolation have been individually designed, manufactured and tested prior to their installation.
Each bearing has been specifically inspected and checked to verify its correct installation prior to the start of the concreting works. There are 360 vibration isolation pads in our new building, each of which is unique to its location. Now that the ground floor suspended slab is largely completed and the bearings have been installed the performance of the bearings is being monitored to ensure that the vibration isolation is fully compliant.
The attached aerial photographs show the progress of the first-floor formwork and the ground floor suspended slab works.
