Occupied-building remedial planning

Planning Concrete Spalling Repairs in an Occupied NSW Strata Building

Concrete spalling on a balcony edge, façade, soffit, car park or common-property slab creates both a repair question and an occupied-building delivery challenge.

An occupied strata project must manage access, falling-object risk, residents, vehicles, dust, noise, water exposure, investigations, changing quantities and formal inspection points. This guide focuses on delivery planning. For causes and repairability, read what concrete remediation means. Building-specific diagnosis and repair design require appropriate professional assessment.

Safety first: do not disturb loose concrete or enter an affected area where falling material, instability or another immediate hazard may exist. Isolate the area where appropriate and obtain competent advice.

Plan the repair and the occupied building together

Start with condition evidence

Assemble drawings, defect history, photographs, previous repair records, water-ingress information and consultant reports. Visual inspection, sounding, mapping, scanning, opening-up, testing or structural review may be required. Distinguish observed symptoms, accepted causes and the final repair design. See the visual-versus-intrusive investigation guide.

Map repair zones and constraints

Record elevation, level, element, approximate extent, exposure and access for each area. Map balconies, windows, car spaces, pedestrian routes, entrances, deliveries, emergency egress, sensitive occupants, work-hour limits and daily handback requirements alongside the defects.

Choose access for the whole sequence

Scaffold, elevated work platforms, suspended access, rope access or a combination may be considered by responsible specialists. Account for coverage, repair depth, debris containment, ground and anchor conditions, public interfaces, duration, repeated inspections and protection of completed work.

Plan temporary and daily controls

Define exclusion zones, overhead protection, containment, dust, noise, vibration, water management, vehicle and finish protection, balcony or window access, cleaning, resident notices and wet-weather response. Identify who installs, inspects, changes and removes each control.

Use hold points for repetitive work

Project-specific hold points may cover accepted access, a trial repair, removal limits, reinforcement condition, substrate preparation, repair material, application thickness, curing, protective systems and zone records. The responsible designer or consultant should define technical acceptance criteria where required.

Control changing quantities

Spalling areas can change after sounding or breakout. State how areas, depths, reinforcement treatment, replacement bar, formwork and access changes will be measured and authorised. Use baseline quantities, agreed rates where appropriate, photographs and timely notice.

Coordinate residents, specialist partners and handover

Issue a building-specific communication plan before mobilisation. Occupants need work-zone dates, access restrictions, noise periods, balcony or window requirements, vehicle impacts, a contact pathway and the response to weather or discoveries.

Where specialist access, engineering, testing or licensed trade inputs are required, SCE may coordinate appropriately qualified, registered, licensed where required, insured and compliant third parties. Their roles and responsibilities are documented for the project; their identities are not published as a general supplier list.

Close each zone before access moves. Collect required photographs, inspection records, material information, measured quantities, approved variations and completion sign-off. Final closeout can then be organised by elevation, level or repair reference.

Frequently asked questions

When is a concrete spalling assessment recommended?

Prompt review is appropriate where concrete is loose or falling, reinforcement is exposed, deterioration is changing, water entry is recurring, a structural element may be affected or the area is above residents, pedestrians or vehicles.

Why do strata owners need a spalling assessment?

An assessment can help distinguish the visible symptom from the extent, cause, structural significance and repair pathway. It also supports access planning, quantity baselines and a more comparable scope.

Can residents remain during concrete spalling repairs?

Sometimes, with project-specific staging and controls. Suitability depends on location, risk, access, noise, dust, egress, temporary protection and the building’s operational requirements.

Can a fixed price be obtained before opening-up?

Only to the extent the condition and quantities are sufficiently defined. Where uncertainty remains, the tender should state assumptions, provisional quantities, rates, measurement rules and variation controls.
