Cladding project guidance
How Cladding Installation Is Planned and Checked
A reliable cladding installation process begins before panels arrive on site. Approved details, substrate condition, access, interfaces, responsibilities and inspection points all affect the construction sequence.
This guide explains practical planning and quality checks without replacing the approved design, manufacturer requirements or project-specific practitioner responsibilities.
Planning Starts Before Installation
The project team should confirm the scope, selected system, approved documents, actual building condition, access strategy and responsibility matrix before fabrication or installation proceeds.
Important: installing a particular panel does not automatically establish whole-of-facade or building compliance. Product selection, design, evidence, interfaces, installation and certification responsibilities must be verified for the project.
What Must Be Confirmed Before Work Starts?
Existing building conditions
- substrate type, condition and capacity;
- dimensions, levels and tolerances;
- windows, doors and penetrations; and
- roof, balcony and parapet interfaces.
Responsibilities and approvals
- design and construction responsibilities;
- inspection and hold points;
- registered-practitioner roles; and
- approval and certification requirements.
Unverified assumptions can lead to fabrication errors, water ingress, rework, programme delays or responsibility disputes. Latent conditions should be documented and resolved before they are concealed.
Substrates and Façade Interfaces
Many cladding defects occur at interfaces rather than through the centre of a panel. Windows, doors, balconies, parapets, roofs, corners, penetrations and transitions between materials require coordinated details and the correct construction sequence.
Corrosion, water damage, inadequate support, misalignment, unexpected materials or dimensional differences should be recorded and addressed before covering the substrate.
Access and Occupied Buildings
Scaffolding, mast climbers, elevated work platforms, rope access or another suitable system may affect safety, sequencing, cost and the amount of façade that can be opened at one time.
Resident access, emergency paths, deliveries, storage, weather protection and temporary restrictions should be coordinated for the actual building and workface.
A Typical Cladding Installation Sequence
This general sequence is a planning guide, not a substitute for the approved design or project inspection plan.
- Confirm scope and responsibilities. Identify the approved documents, construction scope, consultants, registered practitioners and inspection authorities.
- Survey and verify dimensions. Check openings, levels, tolerances and interfaces before fabrication or installation proceeds.
- Establish access and work zones. Coordinate access, public protection, exclusion zones, deliveries and stakeholder notifications.
- Remove existing materials where required. For recladding, use a controlled sequence with temporary protection where necessary.
- Inspect and prepare the substrate. Resolve condition, alignment, support and latent defects before concealment.
- Install interfaces and supports. Complete specified membranes, flashings, drainage paths, fire-stopping, brackets, rails and fixings in the approved order.
- Install and align panels. Maintain required joints, movement provisions, clearances and interface details.
- Inspect and close out. Record inspections, complete defects and compile required handover evidence.
Latent Conditions Need a Controlled Response
Existing façade work can reveal concealed corrosion, water damage, unsuitable framing, undocumented materials or dimensions that differ from the available records.
Construction should not continue on an unsupported assumption. The condition, affected detail, responsibility and required review should be documented before the work is covered.
Design, Construction and Certification
SCE may undertake or coordinate cladding construction within an agreed scope, with awareness of applicable NSW Design and Building Practitioners requirements and SCE's relevant NSW DBP registration.
The responsible designer, registered practitioner, façade or fire consultant, certifier and other professionals must still perform the functions allocated to them.
Cladding Installation Quality Checks
Before concealment
- substrate condition and repairs;
- support and fixing locations;
- membrane continuity;
- flashings and drainage; and
- concealed interface details.
During installation
- panel identification and condition;
- approved fixings and spacing;
- joint widths and alignment;
- movement allowances; and
- penetrations and edge details.
Before handover
- final visual inspections;
- defect close-out;
- required test records;
- product information;
- construction photographs; and
- approved handover documents.
Testing, approval or certification should only be described where it is genuinely required, completed and supported by the responsible party's evidence.

Frequently Asked Questions
What should be checked before cladding installation starts?
Confirm the approved details, selected system, substrate condition, actual dimensions, access, interfaces, responsibilities and required inspections before fabrication or installation proceeds.
Why are substrate checks important?
The substrate must provide suitable support for the approved system. Damage, corrosion, misalignment or unexpected construction can affect fixing design, sequencing and the need for further review.
How are flashings and weatherproofing interfaces checked?
Required membranes, flashings, sealants and drainage paths should be installed in the approved sequence and inspected before later work prevents access.
What happens when latent conditions are found?
The condition should be recorded, the affected work controlled and the responsible project parties engaged before an unsupported change is concealed.
What quality records should be retained?
Records may include approved documents, product information, photographs, inspection checklists, hold-point releases, test results and defect close-out information.
Does a non-combustible panel make the whole façade compliant?
No. Suitability can also depend on the complete system, design, substrate, cavities, interfaces, fire-stopping, fixings, evidence and installation.
Can SCE review a proposed cladding installation scope?
SCE can review available project information and assess construction suitability subject to scope, access, approvals, safety, responsibilities and commercial fit.
