Facade Work at This Scale

The word facade gets used loosely, so it helps to be clear what changes once a building passes a couple of storeys. The wall stops being something a carpenter fixes to framing and becomes an engineered assembly, designed by somebody who calculates the loads, supported on brackets and rails sized for those loads, and certified as part of a permit. The materials arrive with test reports rather than colour charts. The people who sign it off are a registered building surveyor and a structural engineer rather than a builder with a good reputation. Reputation still matters and it no longer substitutes for documentation. An owners corporation asking for both is asking for the normal standard.

Access is the second difference and it drives more of the cost than owners expect. Reaching a wall eight floors up means a swing stage suspended from roof anchors, a mast climber standing off the building, or an elevated work platform with the footpath closed underneath it, and every one of those has a hire cost, a setup cost, an engineering sign off and a permit somewhere. On many facade jobs the access is a larger line than the panels. That is not padding and it does not respond to negotiation. It gets quoted against the form and height of the building rather than by the square metre.

Third, the decision moves out of one person's hands. A homeowner picks a contractor and a material and then lives with the outcome. In an apartment building the facade belongs to everybody jointly, which puts the decision with the owners corporation, which means a committee, a manager, a resolution, a levy or a loan and often a consultant engaged to run the process. Individual lot owners cannot commission work on it, even work on the wall outside their own balcony. Requests of that kind go to the committee rather than to a contractor. Understanding that early saves a good deal of frustration.

Commercial and retail buildings run a similar process with a different cast. A building owner or a manager makes the decision, a consultant specifies, a head contractor delivers and a surveyor signs off, and the tenant is usually the one complaining about the leak that started it. The technical questions are the same as on an apartment building. What differs is that a single owner can decide quickly, which is why commercial facade rectification tends to move faster than residential. Nobody has to call a general meeting to approve a levy.

Older commercial buildings in Victoria bring a category of work that has nothing to do with cladding panels at all. Concrete framed buildings from the 1960s and 1970s spall at the edges of slabs and soffits as reinforcement corrodes and expands, and that presents as falling concrete over a footpath rather than as a fire question. Concrete cancer and spalling repairs covers the mechanism and the repair. It sits on the same scaffold or swing stage as any panel work, which is why the two frequently get done together.

Heritage facades in the Melbourne CBD and the inner suburbs are the other specialist stream. Masonry facades retained in front of new construction, tuckpointed brick elevations on commercial buildings, rendered and moulded frontages needing conservation rather than replacement, all of it requires trades and consents that ordinary facade contractors do not carry. Masonry is dealt with on the brick cladding systems page, while work judged on how it looks sits on the architectural cladding page. Facade retention behind new construction is a structural exercise before it is a conservation one. Engaging the right consultant early is what keeps those two from getting confused.

The State Programme and Where a Building Sits In It

Two fires shaped how this state approaches facades. The Lacrosse building in Docklands lost eight storeys of facade to a fire that started with a cigarette on a balcony in November 2014, while the Neo200 tower on Spencer Street produced a near identical event in February 2019, with residents out on the street overnight. Neither event killed anybody, which is largely a matter of luck and sprinkler performance. Both demonstrated that a panel with a polyethylene core will carry fire vertically up a building at a speed nobody had designed for. Sprinklers and fast evacuation carried the outcome rather than the wall.

What followed was a state response with three parts. A taskforce examined the extent of the problem, a statewide audit assessed buildings carrying combustible material to establish which were at genuine risk, and Cladding Safety Victoria was established to assess affected residential apartment buildings and fund rectification on them. That agency has worked through hundreds of buildings since. For an owners corporation the practical consequence is that there is a body to ask rather than a vacuum.

Establishing where a particular building sits in that process is the first task and it is not a contractor's job. The building may have been audited and cleared, audited and assessed as requiring work, entered into a funded rectification programme, or never assessed at all. Each of those leads somewhere different, and each of them changes whether engaging a contractor now is sensible or actively unhelpful. The owners corporation manager and the records held by the owners corporation are where that history lives. Where records are thin, the agency itself is the next call rather than a contractor.

Patch repairs on a building of unresolved status are the specific thing to avoid. Replacing panel on one balcony or one elevation without knowing the building's assessment position can complicate the later assessment, muddy the funding case and occasionally create a compliance problem where none existed. Repairs are not forbidden at any stage of the process. What matters is the order, and the order begins with establishing the building's status rather than with a price.

Detached houses sit entirely outside all of this and owners of them should stop reading at this paragraph. The audit and the funding were aimed at multi storey residential apartment buildings, nothing obliges a homeowner to act, and a ground floor extension finished in plain aluminium plank bears no relation to any of it. Media coverage rarely draws that line clearly. The cladding services page and the aluminium cladding page cover the domestic situation properly. Solid sheet and extruded plank on a house are ordinary building products.

Insurance is the reason this matters even to buildings that feel unaffected. Insurers ask about facade materials, and a building that cannot say what its panels are made of is in a weaker position at renewal than one holding a report. Professional indemnity cover for surveyors and engineers has also tightened around combustible cladding, which is part of why documentation is requested so insistently now. None of that is unreasonable, since the market is simply pricing a risk it could not previously see.

Identifying the Material and What Testing Means

Nobody can identify a panel by looking at it, and the confident people are usually thinking of one product among many. Two aluminium composite panels of the same colour, the same joint width and the same thickness can have entirely different cores, and the core is what decides how the wall behaves in a fire. From a swing stage at the fourth floor they present identically. The only reliable answers come from manufacturer documentation or from a sample taken and examined properly.

Core sampling is how an unknown facade gets identified and it costs $900 to $4,500 depending on the number of samples and the access required. A small section is cut, the layers are measured and the core material is identified, which distinguishes a polyethylene filled laminate from a mineral filled one or from solid sheet. The sampling itself has to be done by somebody competent, because a sample taken from the wrong element or interpreted loosely answers nothing. Most facade audits fold sampling in where the original records have gone.

A facade condition audit is the broader exercise and it runs $3,500 to $18,000 depending on the building. A consultant reviews the available documentation, inspects the elevations, identifies the materials present, maps where each one occurs, looks at the support and fixing arrangements, notes water related defects and produces a report with a recommended course of action. For an owners corporation that report is the document everything else proceeds from. Commissioning one before seeking quotes is the difference between a managed project and a sequence of reactions.

Evidence of suitability is the phrase that matters on the compliance side. Under the code kept up to date by the Australian Building Codes Board, anything built into a structure has to be shown fit for the job it is doing, and on the outside wall of a taller building that showing has to rest on test results rather than on somebody's view. Full scale facade fire testing under the relevant Australian Standard is one route, certification against the code provisions is another, and a performance solution prepared by a fire engineer is a third. Which route applies is a matter for the building surveyor rather than the contractor. Ask which route is being relied on and who prepared it.

Australian Standards are published by Standards Australia and referenced by the code rather than being law in themselves. That distinction matters because a supplier saying a product meets a standard is making a claim that a test report either supports or does not. Ask for the report, note which standard it cites and note whether the tested assembly resembles the one being proposed for your building. A report covering a different arrangement of layers is testing something other than your wall.

Four items cover what a supplier needs to send back. A sheet identifying precisely which product it is and what goes into it, whatever test result or independent certificate covers it with the standard named, how it has to be fixed and supported, and the installation instructions the warranty rests on. Any established manufacturer sends the lot without argument and usually within a day. A brochure claim, a colour chart or the observation that a product is much like some better known panel does not answer any of it. Neither does a verbal assurance from somebody who bought the material from a third party. Request the paperwork in writing and keep whatever comes back.

Facade Systems and Engineered Support

Non combustible sheet is where most Victorian rectification lands and the choice is narrower than the marketing suggests. Solid aluminium sheet folded into trays, mineral cored composite panel with documented test evidence, fibre cement in sheet form, and profiled metal all appear on rectified buildings, and each carries its own support and jointing requirements. Installed cost sits at $450 to $1,100 a square metre before access. The spread comes from the panel, the folding, the joint treatment and how much bespoke work each elevation needs.

Support framing is the part that separates facade work from cladding work and it is where the engineering goes. Brackets fixed back to the structure, rails or top hats spanning between them, thermal breaks where required, and allowance for the movement of a tall building under wind and temperature all have to be designed rather than assumed. Add $140 to $360 a square metre. Existing support frequently gets reused on a rectification where it is sound, which the audit will have assessed. Where it has corroded or was never designed for the load, replacement is an engineering decision rather than a preference.

Curtain wall and glazed facades sit in their own specialist world. Unitised systems arrive as factory assembled panels lifted into place, stick systems are assembled on the building from extrusions and glass, and both involve glaziers and facade engineers rather than cladding installers. Spandrel panels between floors are the element most often caught up in cladding questions, since they are frequently the composite material on an otherwise glazed elevation. Replacing spandrels on a glazed facade is precise work and is priced accordingly.

Rendered foam panel appears on the lower and mid rise end of the Victorian market, particularly on walk up apartment buildings and townhouse developments from the 2000s. It behaves differently again, since the substrate is soft and the coating carries the appearance, and repairs need system matched products with fresh reinforcement lapped into what is already there. Cored systems and the documentation they need are covered on the insulated wall panels page, with the finish itself on the render and texture coating page. Generic patching on these walls shows within a season. Matched products and lapped reinforcement are the difference between a repair and a visible scar.

Whatever system goes on, the fixing schedule is site specific and comes from an engineer rather than a manufacturer's general recommendation. Wind loads increase with height and accelerate at the corners and the top of a building, so the schedule tightens in those zones, and a contractor working to a single spacing across an elevation has not priced the corners. Request a copy of that schedule. The schedule is a drawing, it exists on any properly documented facade job, and its absence tells you more than any price on the tender.

Cavity fire barriers are the detail most often missed on rectification work and they matter. Where a facade has a ventilated cavity behind it, that cavity is a vertical path for fire and smoke unless it is interrupted at floor levels and around openings by barriers designed for the purpose. Retrofitting them during a panel replacement is straightforward and cheap relative to the rest of the job. Leaving them out produces a wall with the right panel and the wrong performance.

Access, Height Safety and the Programme

Getting people and materials to a wall is the single largest variable on facade work and there are four common answers. A suspended swing stage hangs from roof anchors and suits tall narrow elevations, a mast climber stands on the ground and runs a platform up a track which suits large areas of repetitive work, an elevated work platform reaches the lower levels from the street, and full perimeter scaffold suits complex low rise buildings. Each has a cost profile and a setup time. Allow $180 to $520 a square metre for access on a typical mid rise rectification.

Roof anchors are the detail that catches buildings out. A swing stage needs certified anchor points, and many Victorian buildings either lack them, have anchors that were never certified, or have certification that lapsed years ago. Testing and certifying existing anchors, or installing new ones, is a prerequisite rather than an extra, and discovering it after a contract is signed delays everybody. Ask about anchor certification at the audit stage. Testing existing anchors is inexpensive and the alternative is a delay nobody budgeted for.

Street occupation adds a layer of administration that owners rarely anticipate. Hoardings, gantries, footpath closures and crane or platform standing all need council permits, and in the Melbourne CBD and the busier activity centres those permits carry conditions, fees and timeframes. A contractor experienced in city work prices and programmes this properly. One who has only worked suburban buildings may not, and the gap shows up as a delay rather than as a cheaper price. Council conditions on a busy street are not something a contractor can negotiate down on the day.

Height safety obligations sit with WorkSafe Victoria and they are not negotiable on this work. Fall prevention, rescue arrangements, exclusion zones below the work, protection against falling objects and competent supervision are all requirements, and the cost of them is inside a legitimate quote rather than an optional addition. Where one price sits notably below the rest on a high rise job, it is worth examining what it assumes about any of the above. Height safety is not an area where a contractor finds genuine efficiencies. It is an area where they either allow for the requirement or do not.

Residents are the constraint that makes apartment facade work harder than commercial work. People live behind the wall, balconies become unusable while a stage passes, windows cannot be opened, noise runs through working hours and privacy is a genuine issue with workers outside bedroom windows. A contractor who has done occupied residential buildings will have a communication plan, notice periods and a sequence designed around minimising the time any one apartment is affected. Asking how they manage that is a fair question and the answer is revealing. Buildings that handled the communication well are the ones residents describe without bitterness.

Programme length surprises owners corporations more than cost does. A mid rise rectification runs months rather than weeks once the audit, the design, the permit, the procurement, the access setup and the staged inspections are counted, and winter weather in Melbourne stops external work more often than people allow for. Building a realistic timeline into the resolution rather than an optimistic one prevents a second round of unhappy meetings. Contractors who work this market routinely hand over a timeline with weather contingency built in. An optimistic programme agreed at a general meeting simply relocates the disappointment.

Balconies, Junctions and Water

Water is the defect that brings most Victorian apartment buildings to a facade consultant, and cladding is often blamed for something else. Balcony membranes that have failed under tiles, junctions between the facade and a window head, penetrations for services, and planter boxes built directly onto a slab all produce the same symptom, which is water appearing inside somebody's apartment. Identifying which of them is responsible takes investigation rather than inspection. Money spent on panel where the real fault is a balcony membrane buys nothing at all.

Balcony waterproofing is its own specialty and its own budget. A membrane laid under tiles has a service life, the drainage falls have to work, the upstand at the door threshold has to be high enough, and the drainage outlet has to be connected to something. Below ground the same principles apply and are covered on the basement waterproofing page. Failure in any of those produces water in the apartment below rather than on the balcony. Rectification costs $380 to $900 a square metre, because the tiles come up, the membrane is replaced and the tiles go back. The balcony tiling page covers the finish side of that work.

Junctions between the facade and everything else are where the remaining leaks live. Window and door heads, sill interfaces, the transition between a glazed section and a solid panel, movement joints, and anywhere a balustrade is fixed through the facade all need a detail that carries water outward. These are the details worth confirming get rebuilt on a rectification rather than reinstated exactly as found. Somebody should be making that call deliberately rather than by omission. Reusing a junction detail that leaked for fifteen years is a decision somebody should make deliberately rather than by default.

Concrete spalling frequently turns up during a facade audit and it is an unrelated mechanism with a similar presentation. Reinforcement in a concrete slab edge or soffit corrodes, expands, and pushes the concrete cover off, which drops material onto whatever is below. Repair comes to $420 to $1,200 a square metre and involves cutting back to sound concrete, treating the steel and rebuilding the cover with a repair mortar. Structural repairs covers the engineering side where the section loss is significant.

Older buildings bring hazardous material questions alongside everything else. Asbestos containing materials in a building constructed before 1990 may be present in facade elements, soffit linings, spandrel panels and service penetrations, and the presumption applies until a laboratory rules otherwise. Identification is dealt with on the asbestos testing and inspection page, and what licensed removal involves sits on the asbestos removal page. This belongs in the audit rather than arriving as a surprise once a stage is already hanging. A positive result changes the programme, the licensing and the waste disposal all at once.

Owners Corporations and How the Decision Gets Made

An apartment building's facade is jointly owned, so the decision rests with the owners corporation rather than with any individual. That means a committee considering a recommendation, a resolution passed at a general meeting, funding arranged through a special levy or through borrowing, and usually a consultant engaged to specify the work and manage the contract. Lot owners cannot commission work on the facade outside their own balcony, however reasonable the request. Understanding that structure early prevents a lot of wasted energy.

The order of events is worth setting out because doing it out of order costs money. Establish the building's status with the state programme, commission a facade condition audit, get the material identified and documented, have a consultant or engineer specify the rectification, obtain the building permit, tender the work to contractors who can price the same scope, resolve the funding, then build. Corporations that collect quotes before the audit end up with prices for several different jobs and no basis for choosing between them. Avoiding that wasted round costs nothing but patience.

Engaging a consultant rather than going straight to contractors is the decision that separates smooth projects from difficult ones. A facade consultant or a building surveyor produces a specification that every tenderer prices identically, reviews the submissions, checks the work against the specification as it proceeds and signs off at the end. The fee looks like an overhead and behaves like insurance. On a project running into the hundreds of thousands, it is the cheapest risk management available. Committees that skip it generally end up paying for advice later at a worse moment.

Registration is the check available on the people involved and the register is public. Builders, building surveyors and engineers working in this space hold registration with the Victorian Building Authority, and the register shows the class each one holds, which confirms whether somebody is registered for the work being proposed. Confirming it takes about a minute at a keyboard. On a facade project the classes matter more than on a house, since a builder registered for domestic work is not necessarily registered for a Class 2 apartment building.

Disputes on this kind of work take a different route from domestic building disputes. Owners corporation matters and building disputes involving commercial or multi unit buildings are dealt with by the Victorian Civil and Administrative Tribunal through its own lists, and the conciliation service covering domestic building work does not extend to every situation here. An hour of advice before a resolution costs a fraction of the same advice afterwards. Committees that take it early rarely regret the fee.

Guarantees on the materials themselves still flow from the Australian Consumer Law, administered nationally by the ACCC. Guidance on what an owners corporation is obliged to do, including the duty to repair and maintain common property, is published by Consumer Affairs Victoria. An obligation to maintain common property does not lapse because the funding is awkward. Committees that document their decision making are in a far better position later than those that simply defer.

Record keeping is the obligation nobody enjoys and everybody eventually needs. The audit report, the material identification and test evidence, the engineering design and fixing schedule, the permit and inspection records, the certificates for roof anchors, the warranties and the photographs taken during construction all belong in the owners corporation records permanently. Buildings change managers, committees turn over and nobody remembers what was done in 2026 by 2040. A complete file also answers an insurer at renewal without a fresh investigation.

Costs in Detail

Investigation comes first and it is the smallest number here. Core sampling and material identification runs $900 to $4,500 depending on how many samples the building needs and how hard they are to reach. A facade condition audit with a written report runs $3,500 to $18,000 according to the size and complexity of the building. Engineering design and documentation for a rectification is usually charged as a percentage of the works or as a fee proposal against a defined scope. Either way it arrives before the construction budget rather than inside it.

Panel replacement in a documented non combustible material runs $450 to $1,100 a square metre before access, with the spread coming from the material, the amount of folding and bespoke work, the joint treatment and how much of the existing support can be reused. Engineered support framing adds $140 to $360 a square metre where it has to be replaced. Cavity fire barriers, flashings and jointing are separate line items and belong in the tender as such. Bundled into a panel rate they become impossible to compare between submissions.

Access comes to $180 to $520 a square metre across a typical mid rise job and it is worth understanding as a project cost rather than a rate. Swing stage hire, mast climber hire, anchor testing or installation, hoardings, permits and traffic management all sit inside it, and the total depends far more on the shape and height of the building than on the area of panel. Reaching a tall narrow building costs more per square metre than reaching a broad low one. The area of panel is a poor guide to what the access will be.

Water related work prices separately and frequently exceeds the cladding on lower rise buildings. Balcony membrane rectification is $380 to $900 a square metre including tile removal and reinstatement. Concrete spalling repair to slab edges and soffits works out at $420 to $1,200 a square metre. Junction and flashing rectification is quoted by the metre against a schedule, and on a building with many openings it adds up faster than owners expect.

Whole building rectification is quoted per project and comparing it to a square metre rate is misleading. Two buildings of the same panel area can differ by a factor of two on access alone, and a building requiring a performance solution from a fire engineer carries documentation costs that a straightforward non combustible substitution does not. Where a building sits inside the state programme, funding assistance may be available, which is a further reason to establish status before committing. Nobody wants to self fund work that was covered.

There is one saving here worth arranging deliberately, and it is a large one. Reaching the wall is the largest fixed cost on a facade project, so everything needing that reach should be scheduled into one period. Panel replacement, balcony membranes, concrete repairs, window sealing, painting, roof plumbing and anchor installation all sit on the same stage or climber, and doing them together rather than across three separate mobilisations can save a very large sum. The audit is the right moment to compile that list. Anything discovered after the stage comes down waits for the next mobilisation.

Around Victoria

The Melbourne CBD and Southbank hold the densest concentration of affected buildings and the hardest access conditions in the state. Narrow street frontages, permanent pedestrian traffic, tram infrastructure, adjacent towers and council permit conditions all shape what is possible, and facade contractors working the city carry the relationships and the systems for it. A suburban contractor pricing a Collins Street elevation will frequently underestimate the administration rather than the construction. Ask what city buildings a contractor has completed. Addresses can be checked in an afternoon and the answers are informative.

Docklands, Southbank and the inner fringe suburbs are where the residential rectification work sits. Buildings from the 2000s and early 2010s, frequently mid rise, frequently with balconies wrapped in composite panel, and almost always occupied throughout the work. Contractors experienced with occupied apartment buildings in those precincts understand the resident communication side as well as the technical one. That experience shows up in the programme rather than in the price. Residents who are told what is happening and when complain far less than residents who are not.

The middle ring activity centres bring a lower rise version of the same problem. Walk up apartment buildings and mixed use developments across Box Hill, Glen Waverley, Preston, Footscray and Dandenong tend to be four to eight storeys with rendered panel or composite on the upper levels, where an elevated work platform or scaffold replaces a swing stage. Access is cheaper and the buildings are frequently self managed, which means the owners corporation has less professional support. Engaging a consultant matters more in that situation rather than less.

Geelong, Ballarat and Bendigo have their own apartment and commercial stock and a smaller pool of facade contractors. Lead times run longer, anybody coming out from the city loads mileage and a bed for the night into the figure, and the specialist trades for curtain wall or conservation work generally come from the city. Ringing local commercial builders first is worth the call. Where nobody local can do the work, consolidating everything into one mobilisation matters even more than it does in Melbourne. Travel and accommodation get charged once rather than three times.

Commercial buildings near the water, whether on the bay, down the Peninsula or around Geelong and the Surf Coast, add exposure to the specification. Fixings and coatings need to suit a marine environment within a few hundred metres of the water, and facade elements on those buildings age faster than their inland equivalents. Anchor points and balustrade fixings deserve particular attention there, since both are structural and both corrode out of sight. A condition audit on a coastal building should say so explicitly. Corrosion at a balustrade fixing is a safety matter rather than an appearance one.

Facade Maintenance and Inspection Cycles

Buildings that inspect their facades on a cycle spend less than buildings that wait for a complaint. A visual inspection from the ground with binoculars twice a year, and a closer inspection from a platform every three to five years, catches the things that are cheap early and expensive late. Sealant failing at a window head, a flashing lifting, staining below a fixing, a panel sitting slightly out of plane, a balustrade fixing weeping rust. None of those is urgent on the day it appears and all of them become urgent eventually. Catching them on a cycle is what keeps the costs small.

Sealant is the single largest maintenance item on a modern facade and it has a service life measured in a decade or so. Joints at panel edges, window perimeters, movement joints and penetrations all rely on a bead that shrinks, hardens and eventually pulls away from one edge, and once water is getting behind it the damage happens where nobody can see it. Replacing sealant on a schedule is far cheaper than repairing what it let in. Budget for it as a recurring item rather than a surprise.

Roof anchors need periodic testing and certification, and lapsed certification is one of the most common problems on Victorian buildings. The anchors are what a swing stage hangs from, so their condition is not a maintenance nicety but a prerequisite for any future facade work. Testing on a cycle keeps them available. Discovering they are uncertified at the point a stage is booked adds weeks to a programme for no good reason. Certification is a scheduled maintenance item rather than a project cost.

Drainage is the maintenance nobody remembers until water appears inside. Balcony outlets, box gutters, overflow provisions, cavity weeps and the drainage path at the base of a facade all block with leaf litter, dust and building debris, and a blocked outlet on a balcony puts water over a threshold rather than down a pipe. Clearing them is an hour's work on a cycle. It prevents a category of leak that gets blamed on cladding.

Washing matters more on coastal and city buildings than owners expect. Salt deposition near the water and traffic film in the city both sit on coated surfaces in the sheltered spots rain never reaches, and coating warranties are frequently conditional on periodic washing. It is the tucked away areas that give up first, which runs contrary to what most owners expect. Washing on a cycle also puts somebody close to every elevation, which is worth having for its own sake.

What to Look Out For

Nothing signals trouble on facade work faster than a contractor prepared to price a rectification before anybody has established what is actually on the building. Until the material is known, the support has been assessed and the water defects have been separated from the fire question, nobody can price the job, and a number produced without that is a placeholder. Ask what the quote assumes about the existing panel and the existing support. A confident answer with no audit behind it is the thing to be careful of.

Watch for silence on the engineering. A wall at height is an engineered assembly, so the fixing schedule, the bracket design, the allowance for building movement and the loads at corners and the top of the building all come from an engineer rather than from experience. A quote with no engineering line, and no engineer named, has either left the cost out or is intending to work without one. At this scale neither of those positions holds up.

Be careful with a price that looks well below the others on a high rise job. Access, height safety, permits, traffic management, resident communication and staged inspections are all real costs on this work and a cheap quote is usually cheap about one of them. Ask specifically what access method is assumed and whether anchor certification is included. The difference between a stage and a climber can be tens of thousands on one building. The answer frequently explains the gap entirely.

Look for cavity fire barriers in the specification. A ventilated gap behind a facade runs vertically up the building and carries fire unless something interrupts it at each floor and around the openings, and retrofitting the barriers during a panel replacement costs very little against the rest of the project. Fitting a compliant panel over an uninterrupted cavity solves only part of the problem. Ask whether barriers are in the scope and where the drawing shows them.

Finally, treat the sequence as seriously as the specification. An owners corporation that establishes status, commissions an audit, gets the work specified and then tenders will receive comparable prices for a defined scope. One that collects quotes first ends up holding prices for several unrelated projects with no way to rank them. The order is the part nobody can fix retrospectively.

How to Get Comparable Quotes

Start with the specification rather than with the building. Facade tenders are only comparable when every contractor is pricing the same documented scope, which is what the audit and the engineering design produce. Where that documentation exists, send it to each tenderer along with the drawings, the fixing schedule and the access constraints. Where it does not exist yet, the honest first step is commissioning it rather than seeking prices. Tendering an undefined scope produces submissions nobody can read against each other.

Give every tenderer the same schedule of questions alongside the documents. The panel product and its test evidence, whether the existing support is being reused and on whose assessment, the engineer producing the fixing design, the cavity barrier provision, the access method and who certifies the anchors, the permits and traffic management included, the resident notification arrangements, the programme with weather allowances, the inspection and sign off points, and the warranties on material and workmanship. Identical wording is what makes the submissions comparable. Send the questions as a schedule to be completed rather than as prose in an email. Answers in a table can be laid side by side; answers in paragraphs cannot.

Ask each of them what they expect to find behind the existing panels. A contractor who has done rectification on buildings of that era will name the likely conditions, usually corroded fixings, a torn or degraded layer behind the panel, missing flashings at heads, and support brackets that were never designed for what was hung on them. One who expects a clean substrate has either not done this work or is not saying. That answer tells you a great deal about how the variations will go.

Read the submissions against each other on method before looking at the totals. Two contractors agreeing on the panel, the support assessment, the barriers, the access method and the programme are competing genuinely and the difference between them is information you can use. One sitting well below the others by exactly the engineering, the anchor certification and the barriers has priced a different project, and the sections above describe what that project turns into by variation four. Take the omissions back to that tenderer and watch the figure. Where it holds firm, you have learned what the low price left out.

Keep the whole project file in the owners corporation records permanently rather than with the current committee. The audit, the test evidence, the design, the permit, the inspection records, the anchor certificates, the warranties and photographs of the support and the barriers before the panels went back on. Nothing on a completed facade can be verified from the ground, so that file is the only account of how the building was rectified. Insurers, purchasers and the next committee will all rely on it. None of them will be able to reconstruct it from the building.
