Remedial works to sea wall and pool area by Strata Engineering Solutions in 2013. Waterfront strata property at Kurraba Rd, Neutral Bay NSW.
PROBLEMS
The existing stone sea wall, located to the western boundary of the property, had deteriorated significantly in areas due to tidal erosion. This deterioration had undermined the structural stability of the timber deck surrounding the pool, which was supported by the sea wall on one side.
The timber deck to the pool area had also deteriorated as well as the tile surrounds and pool lining. A rendered retaining wall adjacent to the pool had cracked in places.
No pool fencing was present to the pool area which was a safety concern and also meant the area did not comply with the requirements of the Building Code of Australia.
SOLUTIONS
SES produced detailed design drawings and documentation for the remediation of the above issues. An application was then made, on behalf of the building owners, to obtain permission from NSW Maritime to lodge a Development Application for the proposed works. Upon receipt of consent from NSW Maritime, SES lodged a Development Application to North Sydney Council to carry out the proposed remedial works.
Tender documentation was produced and sent to specialist building contractors experienced in this type of project for pricing. SES assessed the tenders submitted and provided a recommendation to accept the successful tendering contractor. A contract for the remedial works was drawn up by SES for the proposed works. SES acted as design engineer, project manager and contract superintendant for the works on site.
The remedial works broadly comprised of repairing the existing sea wall by rebuilding sections and providing a new durable finish to the face of the wall. The existing pool lining was stripped, concrete spalling repairs were carried out to the pool structure and a new lining was installed. The existing timber deck and substructure was completely removed and a new treated timber structure and hardwood deck was installed. The stability of the existing deteriorated retaining wall was assessed and found to be satisfactory. A new hardwood timber facing was installed to the front of the retaining wall to match the new pool deck. New pool fencing was installed to the pool area comprising of stainless steel and glass and complying with BCA requirements.
RESULTS
A structurally adequate and durable sea wall and timber deck, as well fully-compliant pool fencing. The appearance of the area was vastly improved, adding significant value for the building owners.
