Pier movement assessed
The observed movement in the existing masonry pier was assessed to define the immediate risk and investigation requirements.
Completed SCE project
Lane Cove School Structural Remedial Project
SCE Corp completed structural remedial and sewer-line replacement works at Currambena Preschool and Primary School in Lane Cove, NSW, during the December 2025 school holidays.
Project overview
Movement was observed in an existing masonry pier. SCE established an exclusion zone, coordinated the required structural-engineer input and delivered temporary support, controlled investigation, permanent structural repairs, replacement of the broken sewer line and reinstatement.
Location
Lane Cove, NSW
Client setting
Preschool and primary school
SCE role
Remedial construction and coordination
Project status
Completed December 2025
Structural repair delivery sequence
The completed works followed a controlled six-stage sequence.
Exclusion zone established
The affected area was isolated to control access while the structural condition and adjoining services were investigated.
Temporary support installed
Temporary structural support maintained stability and load transfer during excavation and removal of affected elements.
Cause of subsidence identified
Controlled excavation exposed the affected footing zone and identified the broken sewer line associated with the subsidence.
Permanent structural repair completed
The approved repair included structural steel and a new permanent footing, delivered to the structural engineer’s design requirements.
Broken sewer line replaced
Replacement sewer pipework was connected before controlled backfilling and final reinstatement of the work area.
School-site, access and engineering controls
The programme and construction sequence were planned around the school setting, restricted access and structural risk.
School-holiday programme
The works were completed during the December 2025 school holidays to separate the construction activities from normal school operations.
Restricted-access delivery
Excavation and material handling were carefully staged for the constrained work area, with the exclusion zone maintained around the affected structure.
Defined professional roles
SCE delivered and coordinated the construction works. Structural design and certification remained with the appropriately qualified structural engineer.

Completed project outcome
SCE completed the structural repair, replacement sewer-line connection, backfilling and reinstatement during the December 2025 school holidays. The affected pier and footing zone were stabilised through the permanent structural works, and the broken sewer line was replaced.

Frequently asked questions
What work did SCE complete at Currambena Preschool and Primary School?
SCE assessed the observed pier movement, established an exclusion zone, installed temporary support, coordinated the required structural-engineer input, completed the permanent structural repair, replaced the broken sewer line, backfilled the excavation and reinstated the work area.
Why was an exclusion zone established?
The exclusion zone controlled access around the affected masonry pier while its movement, the footing zone and adjoining services were investigated and repaired.
What caused the subsidence near the affected pier?
Controlled excavation identified a broken sewer line in the affected footing zone associated with the subsidence. The damaged line was replaced before backfilling and reinstatement.
How were the structural repair and sewer-line works coordinated?
Temporary support maintained stability while the affected area was excavated. SCE coordinated and delivered the construction works, including structural steel, the permanent footing and sewer-line replacement. Structural design and certification remained with the appropriately qualified structural engineer.
When were the Lane Cove school works completed?
All works described on this page were completed during the December 2025 school holidays.
