WHARF STREET, GOSFORD
This multi-tiered waterfront property located in Gosford NSW was suffering extensive structural damage caused by consistent water ingress. Upon early inspection, engineers found that the property had been poorly constructed, allowing water to penetrate through the external balconies into living areas in the apartments below.
The scope of the work requested by the engineers included:
- Removal and replacement of windows and rectification of faulty workmanship
- Removal and replacement of faulty roofing membrane
- Replacement of cavity flashings
- Installation of expansion joints
- Installation of concrete hobs in accordance with the Building Code of Australia
- Installation of new balustrading
- Painting of all external render
The Rectification Process
Remedial commenced the project in early 2015 after tendering a methodology for undertaking the project. Before beginning the works, Remedial erected scaffolding at the rear of the property to minimise the impact on residents.
The first stage of the project involved the removal of the old balustrades, balcony tiles and membranes. Once this was completed, the team began the removal of the apartment windows and glass door assemblies, before installing a torch-on waterproofing membrane system. A flashing was then placed in the appropriate position before reinstalling the door and windows. This procedure was performed on each apartment one-by-one, in order to reduce the impact on residents by ensuring that each home was exposed to the elements for the minimum possible time.
During the next stages of the project, cavity flashings were installed, a torch-on membrane was applied to the surface of each balcony and screeds were applied where necessary. Once this was complete,the legs for the new glass and aluminium balustrades were positioned, new tiles were installedand a suitable expansion jointing system was applied to allow adequate movement of the joints.
The final stage of the project involved the coating of various elements and the installation of the balustrade frames and glass. After the completion of all rectification works, the building was commercially cleaned prior to the final inspection by the engineers. As soon as the completion certificate was issued, the scaffolding was removed.
At Remedial, the protection of the natural environment is always an important consideration. Accredited to Australian Environmental Standards, you can rest assured that for every project Remedial undertake, there is an appropriate environmental program in place to ensure the safety of the natural environment.
For the Wharf Street rectification project, the measures taken included but were not limited to:
- Runoff socks
- Protective sheeting during water blasting
- On-site chemical containment
- Removal, storage and re-introduction of plants which would have otherwise been affected by foot traffic or scaffolding.
