How to Assess a Cladding or Recladding Proposal for a NSW Building
A useful cladding or recladding proposal should let the client understand what is included, what remains uncertain, which evidence supports the proposed system, who holds each responsibility and how the price, programme, construction controls and handover requirements have been formed.
Comparing only the panel description or bottom-line price can conceal major differences in investigation, design, approvals, interfaces, access, protection, testing, records, exclusions and risk allocation. This guide provides a practical assessment framework for NSW owners corporations, asset managers and project teams. It is not a compliance determination, regulated design or substitute for project-specific professional advice.
Key point: compare proposals on a like-for-like scope. A lower price may reflect a narrower scope, different assumptions, provisional allowances or omitted responsibilities rather than better value.
What a Proposal Should Make Clear
Project starting point
Identify the reports, notices, drawings, samples, investigations and client requirements used to form the proposal. Separate verified information from assumptions and unresolved conditions.
Complete work scope
Define the façade areas and system components included, not only the outer finish. Address removal, substrates, framing, support, fixings, insulation, membranes, cavities, barriers, flashings, openings, penetrations and adjoining work where relevant.
Evidence and design basis
State the proposed products and assemblies, the evidence relied on, applicable limitations and the design, review, declaration and certification steps that remain outstanding.
Responsibility boundaries
Allocate client, contractor, designer, engineer, fire consultant, supplier, certifier and other responsibilities. Avoid wording that transfers an undefined design or compliance obligation without the associated scope, authority and information.
Delivery controls
Explain access, occupied-building controls, protection, temporary weatherproofing, staging, hold points, inspections, variations and construction records appropriate to the project.
Commercial and closeout basis
Set out price inclusions, exclusions, allowances, programme assumptions, payment terms, warranty conditions, maintenance requirements and the documents required at handover.
Check the Existing-Building Information First
The reliability of a proposal depends on the information available when it is prepared. Existing drawings, façade reports, fire assessments, product records, approvals, maintenance history, leak records, photographs and opening-up findings may materially change the scope and price basis.
Where concealed construction has not been verified, the proposal should state the assumption, the planned investigation and how a different finding will be managed. A fixed price formed from incomplete information may still contain exclusions or variation triggers that need commercial review.
Questions to ask:
- Which documents and inspections support the proposed scope?
- Which façade areas and concealed conditions remain unverified?
- What opening-up, testing or consultant input is required?
- Who owns the risk if the existing construction differs?
- What must be decided before the price and programme can be finalised?
Review the Evidence for the Complete External Wall
Product identification
Confirm manufacturer, product, model, composition, thickness, finish and intended use. Generic descriptions such as “non-combustible panel” do not identify the complete proposed system.
Evidence and limitations
Review current reports, certificates, appraisals, test evidence, installation requirements, limitations and conditions relevant to the proposed use. Confirm that documents apply to the named product and assembly.
System interfaces
Check support framing, fixings, insulation, membranes, cavities, barriers, flashings, joints, windows, doors, penetrations, parapets, roofs, balconies and other adjoining construction included in the design and scope.
Project-specific requirements
Account for building classification, construction type, exposure, height, geometry, fire strategy, structural actions, water management, thermal and acoustic needs, durability and maintenance.
A product document does not by itself establish that the complete external wall is suitable or compliant for a particular building. The project-specific design, interfaces, installation and applicable approval and practitioner processes remain important.
Compare the Price on a Like-for-Like Basis
Normalise each proposal before comparing totals. Check whether design and consultant services, statutory fees, investigations, access, protection, removal, disposal, substrate repairs, temporary works, services interfaces, testing, inspections, samples, mock-ups, variations, documentation and maintenance information are included.
Allowances and provisional sums should identify what they cover, the assumed quantity or basis, margins and how adjustments will be calculated. Exclusions should be read together with the proposed scope so essential work is not left without an owner.
Keep Regulated and Contractual Roles Distinct
Where the NSW Design and Building Practitioners framework applies, registered practitioners have defined obligations for regulated designs, declarations, building work and variations. Current Building Commission NSW design-obligation guidance should be considered with project-specific advice.
A proposal should identify who prepares and declares regulated designs, who coordinates design information, who carries out and declares applicable building work, who performs specialist inspections and who acts as certifier. SCE Corp can review construction scope, buildability, access, safety, staging, procurement, programme and commercial fit and coordinate delivery where engaged. Specialist advice, regulated design, declarations and certification remain with the appropriately registered or appointed parties responsible for those functions.
A Practical Proposal-Review Sequence
1. Confirm the project objective
Identify the defect, risk, notice, renewal goal or other driver and the outcome the client requires.
2. Reconcile the scope
Map every façade area, component, interface and supporting service to an inclusion, exclusion, allowance or named responsibility.
3. Test the evidence basis
Verify that the proposed products, assemblies and documents are identifiable, current and relevant to the intended building use and design pathway.
4. Allocate responsibilities
Prepare a clear responsibility matrix for investigation, design, approvals, procurement, construction, inspections, declarations, certification and handover.
5. Compare programme and risk
Review approvals, lead times, access, occupied-building constraints, weather, discoveries, hold points, variations and closeout dependencies.
6. Record clarifications before award
Resolve material qualifications and incorporate agreed clarifications into the contract documents rather than relying on informal discussions.
Continue Through the Correct Pathway
Review the primary service pathway for investigating existing cladding and defining an evidence-led next step. Cladding and Recladding Fire Compliance
Review the broader service pathway for suitable cladding remediation and replacement works. Cladding Installation Services
Understand construction planning, interfaces and quality controls for installation work. Belmont Recladding Project
Review relevant SCE project evidence. Cladding Estimator
Prepare an early planning range before investigation, design and quotation. Discuss the Project
Provide the available reports, drawings, photographs, scope and programme for an initial suitability review.
Frequently Asked Questions
Is the lowest cladding proposal usually the best value?
Not necessarily. The lowest total may reflect a different scope, assumptions, allowances, access method, evidence basis, responsibility allocation or handover requirement. Compare proposals on a reconciled like-for-like basis before assessing value.
Does a product certificate prove that the complete wall will comply?
No. Product evidence should be relevant and reliable, but the complete external wall, project-specific design, interfaces, installation, applicable requirements and responsible practitioner processes must also be addressed.
What should be confirmed before relying on a fixed price?
Confirm the scope, existing-building information, design status, quantities, access, inclusions, exclusions, allowances, provisional sums, latent-condition treatment, variation rules, programme assumptions and handover requirements.
How should allowances and exclusions be compared?
Identify what each item covers, its quantity or pricing basis, applicable margins and adjustment method. Then confirm that every necessary part of the work is included elsewhere or allocated to a named party.
Who is responsible for regulated designs and declarations?
Responsibility depends on the building, work and applicable NSW framework. Where regulated designs and declarations are required, they must be prepared or made by practitioners whose registration authorises the relevant work. The proposal and responsibility matrix should identify each role.
Can one document cover every cladding product and building?
No. Evidence has a defined product, system, test configuration, intended use, limitations and conditions. It should be checked against the actual proposed assembly and the requirements of the particular building.
What warranty information should be compared?
Review the responsible party, covered product or work, duration, exclusions, maintenance conditions, transfer provisions, claim process, remedies and records needed to preserve coverage. Do not rely on a headline duration alone.
How can SCE Corp assist with proposal assessment and delivery?
SCE can review construction scope, buildability, access, safety, staging, procurement, programme and commercial fit and coordinate suitable building and remedial works. Regulated design, declarations, specialist advice and certification remain with the responsible registered or appointed parties.
