Tales of Woe – Variations, warranties, costs, and deflections

1.            Architect commissioned on minimum terms basis for about 30 townhouses of three basic plan formats and three varying cladding types in several blocks on a site with varying levels excavated out of sloping land.  “Typical” plans elevations sections and retaining walls only provided – almost all at 1:100 – with 1:20 details at a few critical/typical junctions; generic specification with “choices” all left for construction phase.  Developer runs the whole of the tendering/contract admin/project management using NZS3915 (no “engineer to contract”):  directly contracts out the bulk excavation which is done as the tenders are submitted for the building construction.  Disputes arise when contractor seeks variations as follows:

a.            Recessed shower bases (ie cut 12mm or so into the walls – not detailed) compromise fireratings at timber inter-tenancy walls and require substantial nogging and adaption of prenailed frames

b.            Chosen kitchen extract requires ducting to end wall of unit, boxed out ceilings, adaption of prenailed  frames, additional gib fixing and finishing

c.             Elevations show where the different claddings were to be used, but there are additional costs of detailing to deal with changes in cladding types within the plan types (typical details apply to cladding types but not junctions between them)

d.            Additional costs to accommodate trimming of bulk excavation

e.            Additional costs of retaining walls varying between architect’s drawings and final levels created by bulk excavation.  Ditto various site-directed stormwater items required to suit.

f.             Additional costs because the bulk excavation creates a steep embankment for which no retaining wall is provided in the contract until after there is a subsidence and damage sustained to the main contractor’s half-built work.

2.            Architect engaged for gym with specialist sprung floor system.  After much research, local franchisee of global brand is appointed as nominated subcontractor, at least partly on the basis of the warranty available.  Construction proceeds to completion to everyone’s satisfaction and the warranty formalities are actioned.  A few short years afterward it is apparent that the floor is failing, and the only remedy is total replacement at a significant sum.  Local franchisee immediately folds, and the global principal is called upon to make good the warranty.  Polite letter by overseas airmail points out that the global entity unconditionally stands by their product but offers no underwriting of franchisee performance and therefore from their point of view the matter is at an end.

3.            Clients engage architect for fancy house on their existing site and on the basis of a very preliminary chat about psm costs which sets the preliminary budget.  Many changes by the client along the way  substantially add to costs, but the architect is determined to create a masterpiece nevertheless.  Clients independently seek builders estimate at an early stage, arrange finance and update architect on that basis, shift out to another house they owned and had previously rented out, and demolish existing house.  18 months delay while client diverts available funds into unrelated business opportunity.  Project recommences and is eventually put out to tender.  Wildly varying tenders received, but the lowest is significantly above any expectations:  the client abandons the project and seeks damages from architect.  (It later transpires that the business has sucked them dry also, and that they are content with minor alterations to their alternative accommodation instead).

4.            Structural engineer designs steel beam (ie calculations, PS1 and pencil sketches) for architect to incorporate into drawings.  House completed (to the delight of the clients), but the floor over the beam is very bouncy and gib ceilings crack.  Ceilings pulled away, beam strengthened, clients have to move out and pay for motel while the remediation is completed at engineer’s cost.  Architect’s final fee claim returned unpaid and with a short note that if it is pursued there will be a counter-claim.

Tales of Woe – the perils of admitting liability

In a recent newsletter to engineers there was a case study from the late 1970s that is still relevant – even to architects – today.  (a contribution from Board Member Michael Davis)

The Facts

An engineer was engaged by a contractor to design temporary works for a bridge project.  After some work was carried out it was discovered that it had been incorrectly set out.  The engineer agreed that they had made an error and to pay for the correction of the fault.  This was done as a verbal agreement, and the engineer did not consider it worthy of advising their insurer because the matter had been settled amicably.

The bridge was eventually completed but at the same time the contractor’s company went into liquidation.

The appointed receiver then laid a claim against the engineer alleging that their error had contributed to the delay and the company’s financial difficulties.

The liability that arose from this (including all the legal fees to defend the action) was not covered by the engineer’s insurance because they had not advised their insurer.

What are the Professional Liability Lessons?

In the first instance, the engineer should not have admitted liability – regardless of how obvious the error might have been.  The engineer should also have notified their insurers of the event as soon as they were aware of the likelihood of a claim being made against them.  Both issues are a standard requirement of your contract with an insurer for Professional Indemnity. 

Further, in trying to settle the matter quickly and amicably, the engineer should have obtained a written discharge from the contractor in respect to the claim and any matters arising from the claim.  In the absence of that, and of some insurance and legal advice on the wording of such an agreement, the engineer left the door open for a further claim.

Tales of Woe – site and survey matters

A few examples of site and survey matters:

Architect designs a building to the maximum allowed by height to boundary controls.  One or more of the following happens (ie these have all happened on one or more jobs!) and the breach will result in replanning/rebuilding/resource consent with attendant costs and delays:

Owner points out boundary position lies just inside a thick wide hedge.  Regrettably, owner is mistaken, and the boundary is at the other side of the hedge, and at a much lower level.

Architect obtains survey and designs to it.  Surveyor wrongly draws up the site plan (or draftie wrongly reads it) to show the boundary at the top of a retaining wall instead of at its base.

Builder thinks the architect is a wally, and after discussion/agreement with the owner helpfully raises the floor level 200mm without the architect being told or noticing on a site visit.

Boundary levels are more or less consistent, except for a small section which has a pronounced dip about 1.2m across and 400mm deep.  Architect ignores it but the council doesn’t!

Construction proceeding smoothly, framed up with roof about to go on.  Some bright spark in the check-box department of the local council realises that they have not yet got a certificate from a surveyor to verify the HIRB and sends out a routine letter.  Surveyor duly reports to architect that the horizontal dimension between the building and the boundary is 700mm less than the architect used for the roofline.  Architect sadly discovers that at 1:100 scale the dimension line drawn parallel to the boundary is exactly 700mm from it!

Old house in poor condition is to be repiled, refurbished and extended along the boundary. Site levels are taken before the design is started.  Floor level of the extension is later designed to be level through to the existing old house.  After the repiler has straightened and levelled things up, the old house floor level where it meets the new extension is rather higher than before.

Tales of Woe – Site information

Here are some recent or memorable claims arising out of site information.

  1. Ancient large bricked stormwater main was not where it was expected to be:  collapsed during site excavation
  2. Public drain position plotted on council records.  Test drills identified “safe” locations for larger diameter piles which in due course were driven.  Two went through the known but mis-recorded drain, and on review it was discovered that the test drills self-plugged the hole they had made:  so the drain was found, but that was not known at the time.
  3. Piles drilled, reinforcing placed, concrete pour underway.  The volume of concrete in one pile was significantly more than expected:  it turned out that it had been steadily blocking up a public drain seven metres below ground level.
  4. Until a justifiably grumpy roofer complained, no one had flagged the issue that the roof was far too close to overhead power distribution lines.
  5. Infill house on rear site built in a dip, which later proved to be an unrecorded overland flow path, later blocked by well-meaning landscaping efforts, thus creating a local lake around the house.
  6. House built according to the local authority wind zone requirements, but the specific site had a much higher wind exposure.  The cladding details and structural bracing proved inadequate despite a structural engineer’s involvement.
  7. Uphill site retaining wall of non-critical setout but defined height was built ahead of setting out the house.  The builder ignored the (perhaps sparse) drawing information defining the house floor levels and instead set it out from the retaining wall:  a difference of 500mm.
  8. Builder issued with consent-application set of drawings to quote from.  During consenting, the Council required the building to be lifted by 500mm to avoid flooding.  Builder ignored the consent-issue drawings and built from the ones they had quoted on.  Not discovered until the pre-line inspection.
  9. Mis-understood or mis-dimensioned setout drawings, discovered (a) after piles driven (b) after major project boxed and reinforced but in final pre-pour check (c) after slab poured (d) in the attempt to join up the new roof to the existing one.
  10. Mis-understood height control lines:  (a) drafting line wrongly assumed as boundary (b) boundary assumed at top of a retaining wall instead of the bottom (c) position of boundary assumed within large unruly hedge which also concealed a steep drop (d) builder unilaterally decided to set the floor level higher than designed for (e) neighbour (and therefore council) placed significant importance on what reasonably seemed to be an insignificant dip in the boundary profile (f) protracted neighbours dispute over what was the “natural” level at the boundary, and at what date that should apply.

A Grim Tale About Piggies and Wolves.

Once upon a time there were three designer pigs:

The first designer pig designed a house of straw, but along came a shower of rain and because the walls weren’t protected by eaves, and the window details were appalling, and the waterproofing system comprised only paint over dodgy plasterwork, the walls rotted and the house fell down.  Along came a wolf, and the design pig was roasted.

The second designer pig designed a house of timber, which was all very well and good, but the pig did not stick around to see if the house got built properly, and the piggies who lived in the house closed all the windows to stay warm in winter, and didn’t venture outside to clean out the gutters or even stop the weeds growing up very close to the walls.  The insulation and building wrap ensured that the walls were always wet inside and before very long the house was a great place for growing mushrooms, many of which were not found until the wall linings were removed.  Along came a wolf who was keen to see that the piggies who lived in the house grew big and fat instead of being weak and sick from the dampness.  He made sure that the design pig paid the costs of making the piggies and the house better again.  

The third designer pig was much smarter and more stylish.  Of course, a brick chimney was out of the question because of the earthquake risk, and possibly because a wolf could fall down it.  Instead, one of those very stylish metal fireplaces was put in to keep the piggies who lived in the house healthy and happy.  And everyone was.  Well, for a couple of years, anyway.  Because what happened then was that the house suddenly burst into flames.  The wolf was not at all happy that the piggies were overcooked and he asked a wise old owl what could have possibly happened.  The owl yawned and said (in a doleful way) “pyrophilia” which the wolf looked up on Google (with some surprise!) and found should have been “pyrophoric carbonization”. 

And the moral of this story? 

1.            Whenever an aspect of design or construction is critical to the performance of the completed building, both design and installation are critical activities.  In these cases, proper detailing and specification, observation during construction, and review of manufacturer’s installation requirements may have saved the designer pigs’ bacon. 

2.            Any hot surface in proximity to timberwork has the long-term potential dry out the timber to the point that spontaneous ignition may occur at temperatures less than would happen by the application of a direct flame.

3.            If reliant on intumescent products for fire protection, do not ignore the need to provide specific fixing details, clearances for expansion, and installation conditions applicable to that product.

4.            If the ongoing satisfactory performance of an element of a building – or its continued warranty cover – is reliant on maintenance, then it is in the interests all concerned that the need for that maintenance is made clear.

5.            Wolves can be scary and hungry

Failure to do what others in similar circumstances would have done.

Negligence test

  • Was a duty of care owed to the claimant?            
    • Was that duty breached?
    • Did the claimant suffer a loss
    • Was the loss caused by the defendant?
    • Was the loss reasonably foreseeable?

All questions must be answered YES for claim to be established

Defences available

  • If one of the above five questions is answered NO
    • The claim is contractually barred (time or money)
    • The claim is statute barred (time limitation, etc)
    • The claimant contributed to the loss.

Duty of care in contract (1)

  •  Described in the contract: 

                hence importance of having written engagement terms

                and having them signed and returned by the client!

  • Described in the Building Act s14D  (responsibilities of designer) Responsible for ensuring that plans and specifications or advice (if followed) will result in compliance
  • Domestic projects:  described in the Consumer Guarantees Act:

                done with a reasonable level of skill and care

                fit for the purpose you and the customer agreed on

                cost a reasonable amount, if a price wasn’t agreed beforehand

                completed in reasonable time, if timeframe wasn’t set before.

Duty of care in contract (2)

  •  Domestic/Residential projects:

Under Consumer Guarantees Act, a $ limitation cap included in the terms of engagement (i.e. contract for service) for a residential project will be of no effect:  the liability cannot be capped.

In relation to residential contracts, the minimum/default building contract terms are set out in s6 of the Building (Residential Consumer Rights and Remedies) Regulations 2014, but under s362B of the Building Act, these do NOT apply to design.

Duty of care in tort

A tort arises when a party owing a duty of care to others breaches that obligation, and that breach results in a loss (or “damage”) to those others. Scope is established by case law, not (generally) by legislation

To whom do you owe a duty of care in tort?

It depends!  Basically, anyone who might foreseeably be affected by your actions

When does a duty of care arise?

It depends!  But if you are involved in your professional capacity, you are                                             expected to have regard for the interests of those affected by your actions, to the      extent that others in your profession would, if placed in a similar situation.

Duty of care in tort – Examples

Example 1 – Concurrent claim in contract and in tort: The architect designs a defective building, which the client on-sells to others. The new owners could bring a claim for damages against the client in contract (pre-sale representations) and against the architect in tort (duty of care to owners/users of the building).  The client could bring a claim against the architect in contract (design/observation failures), and in tort (duty of care extended beyond contract to include owners/users of the building).

Example 2 – Duty to WarnAn LBP Carpenter was working as an employee for the non-LBP building contractor who was “cutting corners” in a house weathertight remediation project.  The LBP Board decided that the LBP had a duty to inform the owner that some of that work was inadequate or defective. The Board had regard to the significance and potential outcomes arising out of the defective work.

Example 3 – The Disappearing DeveloperApartments and townhouses have been the source of numerous NZACS claims.  It is not unusual for the developer to be unable to fulfil a later claim by the new owners. The architects or designers (and the Council) are routinely called upon to make up the shortfall, on the basis that they owed a duty of care to the purchasers.

Joint and Several Tort Liability

                The Claimant:

  • may seek full recovery from each or any parties that contributed to the damages.
    • is not (usually) concerned about who pays (if anything) to make up settlement sum.
    • cannot claim more than their actual loss, nor for any loss caused by their own negligence.

                The Designer/Defendant:

  • is liable to the extent that they contributed to the damages.
    • is potentially 100% liable for the damages arising out of the design defects.
    • if not engaged for site observation, will not be liable for construction defects
    • if engaged for site observation, will be liable for the damages which arose as a result of their failure to observe, and take action

Joint and Several Tort Liability – Examples

Example 1 – Insolvency:  In a leaky building claim, all the defects were the result of poor construction.  The Council had signed off CCC.  During remediation, it became clear that the original building inspector should have picked up the defective work. The owner sued all and sundry, but only the Council had the funds available to meet any settlement.  The ratepayers paid for all of the remediation.

Example 2 – Inadequate detailing: Similar scenario, but the builder was still in business and had meagre assets. The designer had nothing to do with appointing the builder or attending to the construction phase of the project.  But the designer had failed to detail a critical junction, and the builder’s solution was the reason for the leaks. Settlement was proportional: 15% builder, 15% designer, 70% Council.

Example 3 – Contributory NegligenceThe designer had detailed the relationship between the garage door jambs and the strip drain across the garage door intended to catch surface water flowing down the drive. Damage was caused because that detail was not followed on site. But photos showed that the owners had failed to dispose of fallen leaves and failed to clear the strip drain, with the result that the same flooding and damage would have occurred regardless of the builder’s faults.  Remediation costs were apportioned accordingly.

Limitation Defense (1):

In relation to “building work” claims:

  • usual liability is 6 years from the time the work done      (diagram = “A”)
    • possibility of a 3 year “late knowledge” extension.                (diagram = “B”)
    • 10 year longstop is provided by the Building Act            (diagram = “C”)

Limitation Defense (2):

In contract:

Legal proceedings related to a breach of contract cannot commence after 6 years from the date of the act of omission.

Shorter limitation periods may be contractually agreed, but insurance cover will not respond to claims with a contractual limitation period beyond the statutory 6 years.

In tort:

Legal proceedings cannot commence after 3 years from when the facts giving rise to the claim were known or ought reasonably to have been known. 

Copyright

  • Generally, the person who commissions a work owns the copyright. 
    • NZIA AAS terms reverse that:  the architect owns the copyright, and the client has the right to use the design for the purpose intended by the engagement agreement. 
    • If you don’t have a signed AAS agreement, you may not be able to assert copyright.

Copyright:  Examples

  • AAS not signed: Architects had a specific agreement with clients which included terms that their project was to be unique.  The AAS was part of the agreed terms, but it was never signed.  The clients brought a copyright claim on the basis that their design was later used elsewhere.
    • Copyright assigned?  A project was designed by a director of a firm, who then left, taking the construction phase of the project with him.  A dispute arose over whether the copyright in the design was also transferred.
    • Product replication: A firm issued tenderers with a photo of a furniture item they required to be included in the priced contract.  The furniture designer claimed on the basis that they alone were to be the only possible suppliers of that item.

NZRAB Complaints

The test is negligence, NOT gross negligence.  This may be a low bar, and the complaint may proceed ahead of other dispute processes which might have confirmed the facts, circumstances and contract responsibilities.  It costs a client very little to complain, but involves a LOT or effort and angst to defend.      

BEWARE!

NZRAB Complaints – Examples

Example 1 – Testing the evidence:  The architect advised the client that alterations to their cross-lease property would require approval of the neighbours.  That did not happen.  The client held the architect liable for the resulting problems and the architect conceded in the hope of avoiding punitive costs of the NZRAB process.  When the case was properly tested in preparation for a Court hearing, it became apparent that the complainant’s assertions would have failed.

Example 2 – Leverage:  The architect designed two townhouses for the client:  one for profit and one for occupation. The client’s expectations did not match the commercial realities and they sought to cut their losses by seeking recovery from the architect on the grounds of poor performance.  Their chosen route was to lodge an NZRAB complaint (at minimal cost) as a prelude to court action and/or to gain concessions that might make court action unnecessary.

Example 3 – Having your own cake and eating it too:  The clients engaged the architect for design/observation/contract administration.  The documentation was done accordingly.  The clients then sought to cut costs by curtailing the construction-stage attendances of the architect.  This resulted in unresolved detailing, uncoordinated variations, cost escalations and intermittent site visits by the architect.  The NZRAB complaint was partly initiated because the architect declined to issue a practical completion certificate.

NZACS CLAIM EXAMPLES: 

Communication

  1. Architect appointed to major upgrade/refurbishment project spanning several years, multiple revisions of design brief by a changing client management team:  design required to evolve with aspects of the work uncovered during construction.  Project manager appointed after site operations started:  later multiple problems because context and responsibilities changed and not reliably documented by the parties.  When it comes to a claim, what is in writing is what counts!
  • Architect sends terms of engagement and fees proposal to client;  client instructs the work to proceed (either directly, or by actions in continuing to review and comment on the design) but never actually signs and returns the service contract, or continues to debate its terms.  Architect proceeds in good faith.  Project terminated because:  (a) the designs are never going to meet expectations or (b) getting the required resource consent is too hard or (c) costs are running ahead of budget or (d) divorce is pending or (e) commercial reasons do not support the investment or (f) anything else!  Client then says fees are not payable because the contract either was never signed or because the architect had failed to perform;  architect discovers that copyright may be unenforceable because the contract was not signed;  architect discovers that the interest provisions on unpaid fees may also be voided.
  • A “novel” design feature fails.  Architect digs out several emails to prove that the client was fully aware of the risks and chose to proceed with the design feature.  Client digs out just as many (and perhaps some of the same) emails to prove that they were “talked into” the design feature by the architect.  It is unclear who actually made the decision and on what grounds, but the client’s view prevails on the basis that they relied on the architect’s advice, and the architect had the professional duty to make prudent design decisions.
  • In housing work, the maximum stress level is reached when the construction is almost complete, the client can only see the defects and uncompleted work;  they are stressed out by the endless decisions and costs;  the builder is already overdue and being pressured to start the next project:  the dream is now reality and it may not be perfect.
  • Be aware that if you “recommend” a builder, the client may think they can hold you responsible for their performance.
  • If you elevate your concept of priorities over those of your client, there is a risk it may backfire.  Examples:  The design featured the architect’s selection of views, but when the clients went on site during construction they discovered that their requirement for expansive views had been ignored.  Another where the architect “expanded” the client’s design brief (and budget) to include work not asked for.  Many cases where the architect’s idea of aesthetics has not matched the client’s availability of money

Information

Exceeding building height:

  1. Can be especially contentious in domestic circumstances where neighbours may be concerned about the effects of new work on their sun/views/values.
  • House alteration designed to maximum height envelope:  existing construction required the overall height to be slightly raised above expectations.  Neighbour complained, and the framing had to be removed and the new top floor redesigned.
  • Misunderstanding about the position of the boundary, and therefore the height control planes:  was the actual boundary at the bottom or the top of a change in level or retaining wall near the boundary?  A similar case where there was a misunderstanding about the boundaries in relation to an adjacent accessway:  which side of the accessway generated the height planes?
  • Commercial premises designed to the maximum envelope but the height controls were then exceeded by services installations designed by others.

Site Services

  • Development of residential rear site required drainage to be run through the neighbour’s property.  Client on good terms with the neighbour and instructed the design to proceed.  Neighbour later refused to give consent, and the client claimed on the architect (and refused fee payment) on the basis that the project had to be abandoned. 
  • Building project required piles in vicinity of known subgrade services.  Services plotted and test bores sunk.  Despite best endeavours the piles or test bores unexpectedly encountered the services either not where they were understood to be, and/or whose existence was unknown.  Examples include:  shutting down an area of city electrical supply;  filling a substantial sewer with pumped concrete;  puncturing a water main;  breaking up a major stormwater pipe;  structural redesign to bridge over services or reposition bearing structure. 

Site levels/boundaries/covenants

  • No clear datum for floor levels shown on the drawings, but lid levels of manholes and sumps shown.  House slab level clearly shown, and adjacent retaining walls were dimensioned but the level at their base was not.  Builder built the retaining walls to required dimension and then set out the house from the derived height:  house floor 250mm too high.
  • Rural house designed to specific slab level and submitted for building consent.  Council required increased slab level approx. 300mm above surface water flow path.  House framed up to roof level and council pre-clad inspector noted that the builder had set out the slab level from priced drawings instead of the consented drawings. 
  • Site is subject to both local body setbacks and covenants recorded on the title or terms of sale.  Examples:  Architect assumes (or decides) that one or other of the controls either supercedes the other or is not required to be complied with:  this results in a major redesign and damages paid to affected parties.  Others where the architect advised the clients to gain the approval of neighbours but proceeded without confirming that the necessary approvals had been given and recorded in writing.

Performance

Engineering consultants

  1. Confusion about who is to detail/specify foundation waterproofing or grades versus floor levels. 
  2. Engineers being overly specific about scope of work, leaving gaps (in observation particularly) that the architect is not aware of.  Example – termination of foundation tanking at ground level not protected or perhaps allows water to enter behind it.
  3. Survey/geotech input which does not go far enough out from the immediate area of work.  Examples:  survey stopped at boundary, so the architect was unaware that the overland flow path was restricted = bottom floor of house built in a puddle;  another where engineered fill under a house washed out because of flowing subsurface water.
  4. Conversely/similarly, engineer is required to observe as part of BC requirements, but architect is not:  engineer fails to spot/report architectural issues which might appear self-evident, and architect gets lumbered with the outcome.  Example:  foundations boxed up and reinforcing placed and inspected by the engineer, but an error in the setout in relation to an existing building or boundaries is not picked up and is blamed on the architect’s drawings.
  5. Structural detailing (or approval of shop drawings) which requires a change to the architectural detailing, or which compromises acoustic design or vapour barriers, or creates thermal bridging, but which is not made apparent to the architect.
  6. Services engineers – typically works not performing to required standard, or corrosion problems – swimming pools especially!
  7. Late delivery/changes of structural work which then requires downstream alteration of other design work.
  8. Errors in calculations of lintel deflection, cantilevered slabs, wind loads, capacity of existing structural work to carry proposed new work.

Tolerances and detailing

  1. Inadequate allowance for lintel deflection in the pursuit of minimal detailing:  large sliding windows couldn’t.
  2. Joinery using solid timber sections as panelling did not sufficiently accommodate timber shrinkage/warp/movement.  (Similarly, veneered MDF joinery panels with one “feature” side and another thinner laminate on the reverse which warped accordingly).
  3. Concrete structural items designed on the assumption that specified cement or reinforcing would be used, or end-seating as designed would be provided;  failure occurred because there was insufficient on-site monitoring and/or inferior products were substituted by the contractor.
  4. Technical issues with special places or spaces that require special attention:  Indoor pools and gyms;  coastal or geothermal environments;  localised wind or weather conditions;  animal accommodation;  laboratory pressure differentials;  acoustic separation or isolation;  wet area tiling and associated balustrade installations;  inbuilt fireplaces;  concealed gutters and low-pitch roofs;  materials or details which require secondary protection;  exposed polished concrete floors;  concealed spaces subject to potential condensation or cold bridging;  remediation/recladding or leaky buildings;  flooring slip hazards,  plus many more!!!!

Money

Cost estimation    

  • House client instructs design work to proceed on the basis of a prospective contractor’s guesstimate based on concept drawings.  Final design costs considerably more and the previous contractor refuses to become involved:  architect accused of embellishing the work and adding costs.
  • Very expensive house;  client expands the budget significantly, but the cost of the final design as tendered is still well above that:  client abandons the project and seeks refund of architect’s fees as well as other abortive costs.
  • Client for 4 or 5 townhouses pushed the development options and cost-savings to the extreme and eventually could not achieve what they sought, at which time they lodged a claim in NZRAB as a prelude to a civil claim on the basis that they lost money and potential development profit. 

Certification & payments

  • Client maxes out the funding approvals, and the funders require a fixed cost price without contingencies.  Site or existing building throws up issues which are clearly a contingency item:  cost cutting must be applied elsewhere to free up the necessary funds.  Examples:  On opening up the ceiling in alteration works it is discovered that services and/or structure is unexpectedly present/absent/failed/redundant.  Another where the contractor’s tender was based on using a mobile crane but unforeseen circumstances made that impossible, and extra cost was incurred because a tower crane had to be used.  

Client refuses to accept Variations. 

  • Examples:  Retaining structures requiring to be “beefed up” and/or extended in scope to deal with ground conditions which only became known when excavation done.  Others where the architect has had second thoughts about a better design during the course of construction, and the contractor provides minimal credit for deleted work and maximum cost for the new design. 

The death spiral of Slow Payers: 

  • The client thinks the contractor has overcharged;  the contractor cannot fully pay his subbies;  the subbies prefer to work on other sites where they are getting properly paid;  there are resulting problems in co-ordinating work on site;  the contract period stretches out;  the client thinks the contractor might abandon the site or become insolvent, and with-holds payment as leverage to get the work done (or to retain funds for it to be done by others).  The architect (if doing observation and contract administration) loses hair and sleep trying to get the project back on track, and the client holds the architect responsible for the contractor’s work – or lack of it, whilst the contractor thinks the architect has been biased in under-certifying payments due.  If the architect is not involved in the construction phase, then the client and contractor will both take the position that the drawings and specification were inadequate and the cause of all these problems.  When the client consults their lawyers, the death spiral has firmly taken hold, and the prospect of an amicable resolution fades.

A Grim Tale About Piggies and Wolves

Once upon a time there were three designer pigs:
The first designer pig designed a house of straw, but along came a shower of rain and because the walls weren’t protected by eaves, and the window details were appalling, and the waterproofing system comprised only paint over dodgy plasterwork, the walls rotted and the house fell down. Along came a wolf, and the design pig was roasted.
The second designer pig designed a house of timber, which was all very well and good, but the pig did not stick around to see if the house got built properly, and the piggies who lived in the house closed all the windows to stay warm in winter, and didn’t venture outside to clean out the gutters or even stop the weeds growing up very close to the walls. The insulation and building wrap ensured that the walls were always wet inside and before very long the house was a great place for growing mushrooms, many of which were not found until the wall linings were removed. Along came a wolf who was keen to see that the piggies who lived in the house grew big and fat instead of being weak and sick from the dampness. He made sure that the design pig paid the costs of making the piggies and the house better again.
The third designer pig was much smarter and more stylish. Of course, a brick chimney was out of the question because of the earthquake risk, and possibly because a wolf could fall down it. Instead, one of those very stylish metal fireplaces was put in to keep the piggies who lived in the house healthy and happy. And everyone was. Well, for a couple of years, anyway. Because what happened then was that the house suddenly burst into flames. The wolf was not at all happy that the piggies were overcooked and he asked a wise old owl what could have possibly happened. The owl yawned and said (in a doleful way) “pyrophilia” which the wolf looked up on Google (with some surprise!) and found should have been “pyrophoric carbonization”.
And the moral of this story?

  1. Whenever an aspect of design or construction is critical to the performance of the completed building, both design and installation are critical activities. In these cases, proper detailing and specification, observation during construction, and review of manufacturer’s installation requirements may have saved the designer pigs’ bacon.
  2. Any hot surface in proximity to timberwork has the long-term potential dry out the timber to the point that spontaneous ignition may occur at temperatures less than would happen by the application of a direct flame.
  3. If reliant on intumescent products for fire protection, do not ignore the need to provide specific fixing details, clearances for expansion, and installation conditions applicable to that product.
  4. If the ongoing satisfactory performance of an element of a building – or its continued warranty cover – is reliant on maintenance, then it is in the interests all concerned that the need for that maintenance is made clear.
  5. Wolves can be scary and hungry

A Sad Tale about Fees

A Sad Tale about Fees

Collecting fees can be a hassle. Even if an architect performs flawlessly, many projects (and the associated architectural fees) are vulnerable to the client’s failure to manage the wider issues. The architect needs to keep an ongoing “weather eye” on the client’s character, intentions, competence and solvency.


Not being paid is an uninsured commercial risk, and you need to provision for it, and manage clients to minimise your exposure. This can be difficult when – for good reason – you cannot just cease work and await payment. Nor do you want the non-payment to escalate into a dispute.


This little story is by no means an isolated case, and no doubt you can think of your own variations on the theme. The moral of the tale may be to invoice frequently, explain comprehensively, record correspondence diligently, track/monitor/record all changes to the scope of attendance as they happen, benchmark and follow up on design decisions and cost estimates as often as necessary, and be alert to changes in client circumstances.


An architect undertook design work in accordance with NZIA AAS. The client failed to pay, alleging overcharging. The architects responded with a specific statement refuting the overcharging. They then set out a very full but simple and logical explanation of how the costs were built up; references to the relevant correspondence; how the invoiced fees related to the prior fees estimates and terms of engagement; and the changing circumstances of the project as it evolved. They were confident their work was not at fault, nor that they had ‘overdesigned’ or ‘done more work than requested’ as alleged, because the correspondence confirmed that additional work had been requested and subsequently changed by the client, and the architect’s responses had signalled the fee implications.


The client then responded saying the project and the design cost too much, the architect’s design had been a wasted cost, and that they had engaged another (presumably cheaper) designer to revise things. This throws up the usual issues of copyright; cost control, both in the overall development budget and in the design decisions; and the benefits accruing from all the prior design input which, even if not progressed, informs subsequent designs.


Shortly afterward, the property was put on the market. Perhaps this is another case of a client not being realistic about the costs and risks of development.


Fees recovery is now even harder, because the architect has no control over the recoverable value of what they have produced. Client insolvency, marital strife, or change in ownership structure would increase the problems. The architect is – in reality and despite legal niceties – an unsecured creditor. Then there is prospect that the client could pursue the architect for the losses (“damages”) arising out of the project being abandoned. Perhaps the only good thing to happen at this stage is that your PI policy would respond to that damages claim.


We have observed that some disgruntled clients have sought an unfair fee settlement by threatening to make a disciplinary complaint to NZRAB in the alternative. This extortion is unconscionable, but permissible. The cost and reputational implication to an architect is considerable.
