Project Management near you

SafeWork NSW is direct about the default position: if the construction work is valued at 250,000 dollars or more it is a construction project and a principal contractor must oversee it, and if you do not appoint another party to that role, you automatically assume it. The appointed principal contractor must have the authority to manage and control the workplace in order to discharge the duties that come with it.

Those duties are concrete. Before construction begins, the principal contractor must prepare a written WHS management plan addressing the personnel with health and safety responsibilities and what they are responsible for, arrangements for consultation and coordination with others holding WHS duties, arrangements for responding to incidents, site-specific safety rules and how workers will be informed of them, and the process for collecting and reviewing safe work method statements. The plan must remain accessible to workers throughout the project, and be kept for at least two years where a notifiable incident occurs. Signage must display the principal contractor's name, a 24-hour contact number and the location of the site office.

Because work health and safety is administered by each state and territory's own regulator, the threshold and the detail are set jurisdiction by jurisdiction. Confirm the position with the regulator where the work is happening rather than assuming the New South Wales figure applies nationally.

A head contract with a licensed builder gives you one party responsible for the result, one party carrying the site, and one party whose margin you can see in the price. It also gives you the state's residential building contract and insurance protections in their usual form, because those regimes are written around a builder and an owner.

Engaging trades directly with a project manager coordinating them can save that margin, and it gives you control over who does each package. What it takes away is single-point responsibility. When two trades disagree about whose work caused a defect, there is no head contractor obliged to resolve it, and the gaps between packages, the items that belong to nobody's scope, become yours. It also typically makes you the party that the WHS duties land on unless the appointment says otherwise in writing.

The honest test is whether the saving is worth the exposure. On a small, sequential job it often is. On a complex renovation with overlapping trades, a long programme and structural work, the builder's margin is buying something real.

The classic failure is the gap between packages. Each trade prices its own scope, and the small items between them, the patching, the making good, the odd bit of framing to support somebody else's fixture, belong to nobody until you pay for them separately. On a large job those gaps add up to a meaningful percentage that never appears in the original comparison against a builder's price.

The second is sequence. Trades booked directly are booked around their own schedules, and a delay to one produces a cascade with no head contractor absorbing it. A tiler who cannot start on the agreed date may not be available again for weeks, and the cost of that gap is carried by the owner rather than by the builder.

The third is defect responsibility. With a head contract, a defect is the builder's problem to identify and fix. With directly engaged trades, you become the person deciding which of two contractors caused it and persuading one of them to return. That is a role most homeowners discover they dislike at roughly the same time they discover they are doing it.

Licensing for residential building work is set by each state and territory, with its own classes and its own value thresholds, and the protections that attach to a domestic building contract, including prescribed written terms and residential builders' insurance, generally attach to the builder rather than to a project manager. Check what the arrangement you are contemplating means for those protections in your own state before you sign, because the saving on margin can be smaller than the protection you give up.

Get the project manager's appointment in writing and make it say the things that matter: what they are responsible for, whether they hold any trade contracts, how they are paid and against what, what authority they have to issue instructions and approve variations, what insurance they carry, and, explicitly, whether they or you are the principal contractor for work health and safety purposes. That last clause is the one most often missing, and it is the one that decides who has to produce a WHS management plan before anyone sets foot on site.
