An awning’s age along with recent weather conditions are some contributing factors to structural failures and can pose a significant public safety risk.
This impressive, 1900s heritage-listed building was experiencing significant water ingress across the entire southern facade as well as severe concrete spalling to the eastern facade. Having built a strong relationship with Strata Title Management over the years, and having previously worked at this location, CORE were engaged to undertake detailed investigations and reporting, prepare technical specifications and to manage the tendering a construction phase for the project.
Stage 1 ‘high-risk’ works: initial investigation through to construction – 18 months
Stage 2: in progress
Experts in existing buildings: delivering safe, long-term solutions
CORE was initially engaged to investigate and identify the root cause behind water ingress and concrete spalling issues to the southern and eastern building facade.
Upon completing an inspection of the southern facade via ropes access (enabling a more thorough and cost efficient inspection), it was found that the building’s original lintels were failing, and required full concrete replacement – the main source of water ingress.
On the eastern elevation, a concrete beam supporting the majority of the eastern facade and internal flooring had corroded resulting in the building’s structural capacity being significantly compromised and posed a high-priority
safety risk to residents. During the investigation stage, general spalling to other areas was also found (locations not initially flagged as areas of concern). Upon further detailed investigations, the concrete spalling was significantly more deteriorated than expected with lintels on the eastern facade also failing with multiple structural beams in need of urgent replacement.
Due to the additional, critical findings, it was determined that the project could not be addressed within one scope as originally intended, and that works would need to be staged in multiple phases with high-risk items prioritised.
To date, CORE have delivered a complete in-house structural design solution for the building, managing the project into the construction phase to see all high-risk works completed on time and to budget. Stage 2 works are currently in progress.
