PLUMBING DISPUTES

Plumbing disputes generally arise out of poor contractual documentation and/or defective work and/or materials.

Plans often lack critical detail and specifications are often general and not project specific. Pipes and water management systems are often undersized and/or involve long and complicated runs and/or minimum or inadequate falls due to the presence (or lack) of other building elements. Quotations will often omit (deliberately or accidentally) items of work but not expressly state so on their face and may contain estimates for the plumbing works/fitting supply to be undertaken in the form of PC (Prime Cost) or Provisional Sums that are woefully inaccurate for the work/fittings that are in fact required to be undertaken/supplied. Owners will often choose to supply plumbing fittings but will have no idea as whether the fittings are suitable, and if so, what additional items other than basic pipework must be supplied in addition to the fitting itself and will expect the plumbing contractor to assist with selection, specification and delivery arrangements, and all at no charge. Owners will often request changes to the scope of work and specification as work progresses, whether at the pipe out stage or fit off stage, or anywhere in between. Not all plumbing fittings will function as expected, some will be simply faulty (due to manufacturing defects) and some will be damaged during the construction process.

On the other hand, mistakes and errors are a feature of any building related work and some plumbing contractors fail to have adequate quality assurance processes in place to ensure they achieve the agreed/specified scope of work to the specified standard, and/or to complete their work by the due date for completion.

In the circumstances, it is little wonder that plumbing disputes arise from time to time. There are essentially two types of disputes that we deal with:

  • technical (in the legal sense) disputes – ie disputes that arise out of non-compliance with the technical requirements for making and responding to payment claims under the Construction Contracts Act 2002 (the Act); and
  • merits based disputes – ie disputes about the merits of the parties’ arguments in terms of the construction contract that governs their relationship, or in the case of a contract with a residential occupier, the statutory warranties that are implied into every residential building contract under s362I of the Building Act regardless of whether there is a written building contract. Typical merits based plumbing disputes include disputes in relation to:
    • non-payment for work undertaken;
    • contract interpretation – what the parties actually agreed;
    • scope of work;
    • quality of work;
    • quality of materials;
    • time for completion;
    • payment – the value of the work undertaken in the absence of express agreement as to price;
    • estimates v actual cost;
    • variations – whether certain work is in fact a variation to the agreed scope of work and the value of that varied work;
    • defective work;
    • scope and cost of rectification work;
    • repudiation/cancellation of the contract; and
    • damages for breach of contract.
