Key takeaways
- A skills shortage shifts bargaining power to the subcontractor, so quotes arrive higher, carry shorter validity periods, and are more likely to be withdrawn before you can accept them.
- Availability, not price, is often the binding constraint: a trade may be willing to do the work at a reasonable rate but unable to mobilise within your programme window.
- Subcontractor price movement is driven by the same input-cost pressures that flow through fuel, freight and materials, and those pressures are documented in current market commentary rather than being a mystery.
- Most of the commercial damage happens at the contract stage, when a builder accepts a fixed price from a subcontractor who has priced in no allowance for their own labour scarcity.
- Building Commission NSW guidance on cost escalation makes clear that the building contract itself is the mechanism that allocates who carries an input-cost movement, so the drafting matters as much as the number.
Every builder in NSW has had the same conversation. You send out a package, three trades you have used for years do not respond, and the one quote that comes back is higher than the last job and valid for a shorter window. Nothing about the work has changed. What has changed is how many crews are chasing it.
A skills shortage is not a single event. It is a persistent imbalance between the volume of work available and the number of people qualified and equipped to do it. That imbalance shows up in two places on your job: the rate a subcontractor quotes, and the date they can actually start. Both are commercial risks, and both land on the builder unless the contract says otherwise.
This article is about the money. It looks at why scarce trades price the way they do, how that reaches your tender and your programme, and what you can control when you cannot control the market.
Why a shortage changes the price, not just the availability
When there is more work than there are crews, a subcontractor does not simply raise their rate because they can. They reprice risk. A trade with a full order book has to be persuaded to take your job ahead of another, and the persuasion is either a higher margin, a shorter commitment, or both.
There is also a genuine cost side. A trade operating at capacity pays more to hold onto staff, runs more overtime, and may subcontract part of its own scope to someone else at a margin. Those costs are real and they get passed through. Market commentary on Australian construction costs has repeatedly pointed to input pressures — fuel, freight and materials among them — flowing through to trade pricing, and labour scarcity sits alongside those rather than separate from them.
The practical effect for a builder is that a quote from a scarce trade is not a stable document. It is a snapshot of the trade’s position on the day they wrote it. If your tender sits on a client’s desk for weeks, that snapshot has already aged.
Quote validity becomes a live risk, not a formality
In a soft market, builders treat quote validity as housekeeping. In a tight one, it is one of the largest unpriced exposures in the tender. A trade who quotes today at a rate they can only hold for a short window is effectively telling you where they think the market is going.
Two things go wrong here. First, the quote expires before you have a client signature, and the trade will not honour the number. Second, and worse, the quote is still nominally valid but the trade no longer wants the job, so the price quietly acquires conditions, exclusions or a start date that has moved.
The fix is procedural rather than clever. Diarise every quote’s expiry the day it arrives, and treat the expiry as the date by which you need a decision — not the date by which you hope to have one. Where a package is critical to the programme, ask the trade what they need to hold the number longer, and be prepared for the answer to be a deposit or a longer lead time.
Availability is often the harder constraint
Builders tend to focus on price because price is a number. Availability is a date, and dates are easier to move on paper than in reality. A trade can be entirely willing to do your work at a fair rate and still be unable to get a crew to your site when your programme needs them.
That gap is where programmes quietly fail. The tender assumed a start in a certain week. The trade can only commit to a later one. If you do not ask the question at tender stage, you discover the answer after you have signed the head contract and committed to a completion date.
The question to ask is not “can you do this job” but “when can you be on site, and what has to be true for that to hold”. A trade who tells you they are booked out until a certain point is giving you useful information, not refusing work. You can plan around a known constraint. You cannot plan around one you find out about later.
What moves the rate versus what moves the date
| Pushes the rate up | Pushes the date out |
|---|---|
| Competing demand from other builders for the same trade | A trade booking further ahead than your programme allows |
| Input costs the trade passes through, such as fuel and freight | A crew that is smaller than the work the trade has already sold |
| The risk premium a trade adds for a fixed price over a long build | Sequencing that puts two scarce trades on site at once |
| The cost of holding a quote open while you decide | Approvals or design changes that reset the start window |
How the shortage reaches your tender and your margin
Your price to the client is built from subcontractor quotes plus your own preliminaries, supervision and margin. When the subcontract component is volatile, the whole tender becomes volatile, and the risk concentrates in the period between submitting your price and signing the head contract.
If you tender on quotes that are valid for a short window, and the client takes longer than that to decide, you are carrying the difference. If you tender with a contingency for labour escalation, you may price yourself out against a builder who did not — and who will discover the problem later.
This is the commercial reality of a shortage: the builder who wins on price is often the builder who priced the risk lowest, not the builder who understood it best. That is fine if the risk does not materialise. It is expensive if it does, and it usually surfaces during construction, when your options are limited and your programme is already committed.
What the contract actually allocates
Building Commission NSW has published guidance on rising fuel costs and what they mean for building contracts, and the underlying principle applies to any input cost movement, including labour. The contract is the instrument that decides who carries a cost increase that neither party anticipated.
Read your head contract and your subcontracts with that question in front of you. Is the subcontract a fixed lump sum with no adjustment mechanism? Does it allow for a rise in a defined input? Does it let the trade claim for delay caused by another trade, or by the builder? Does it set out what happens if the start date moves?
A subcontract that is silent on these points does not leave the risk floating. It generally leaves it with the party who has the least ability to pass it on, which in most chains is the builder. The Building Commission’s guidance for trades on contracts, insurance and compliance points in the same direction: the terms you agree at the outset determine what you can recover later.
The mistake that costs the most. Accepting a fixed-price subcontract from a trade who has clearly priced their own labour at today’s rate with no allowance for scarcity, then discovering mid-build that they cannot staff the job. You are left with a contract you can enforce and a programme you cannot deliver, and enforcing it against a small trade usually recovers nothing.
Protecting the programme when trades are scarce
You cannot fix a skills shortage from a site office, but you can reduce how much of it lands on you. The builders who manage tight markets well tend to do a few unglamorous things consistently.
- Book earlier than you used to. If trades are booking further ahead, your procurement lead times have to move with them. Tender the packages you know are scarce before you have finalised everything else.
- Build the relationship before you need it. A trade who has worked with you and been paid on time will take your call ahead of a builder they do not know. That is worth more in a shortage than a sharp quote.
- Pay to terms. Slow payment is the fastest way to lose a scarce trade to a competitor. If your payment cycle is longer than the market’s, you are effectively paying a premium in availability.
- Sequence to avoid contention. Two scarce trades needed on site in the same week is a scheduling problem you created. Where you can, stagger the packages that draw on the same labour pool.
- Keep the client informed. If a start date is genuinely constrained by trade availability, that is a programme risk the client should hear about early, in writing, with the reason stated.
Before you accept a subcontractor quote in a tight market
- Confirm the quote’s validity period and diarise the expiry before you intend to accept.
- Check whether the scope prices labour at current rates or at a rate the subcontractor has held since last year.
- Ask what happens to the price if the start date slips beyond the quoted window.
- Confirm the subcontractor has capacity for your dates, not just willingness to quote.
- Check the subcontract names who bears the cost of a rise in fuel, freight or materials.
- Confirm the subcontractor’s insurance and licensing are current before you rely on the price.
- Read the payment terms against what the subcontractor needs to keep crews on your job.
Worked example: a builder in western Sydney
A builder in western Sydney is tendering a two-storey addition. The package includes structural framing, roofing, and a wet area fitout. At tender, the framing quote comes back at a rate noticeably above the last comparable job, with a validity period the builder considers short. The roofer quotes a reasonable rate but states they cannot be on site before a date well beyond the builder’s draft programme. The wet area trade does not respond at all.
The builder has three options. The first is to tender using the framing number as quoted, assume the roofer will come earlier once the job is live, and find a wet area trade later. That is the cheapest tender and the highest risk, because two of the three assumptions are already known to be wrong.
The second is to tender with the framing number, re-sequence the programme so the roof follows the framing at the date the roofer can actually achieve, and price the resulting extension into the contract period. This costs more up front but the programme is buildable.
The third is to go back to the framing trade, ask what they need to hold the price for a realistic decision window, and ask the wet area trade’s regular subcontractor whether they would take the work if approached directly. This takes time but converts unknowns into numbers.
The second and third options are the professional ones. The first is the one that produces a variation conversation with the client in month two, at which point the builder has no leverage and the client has every right to ask why the risk was not raised at tender.
What to do about your own skills base
The structural answer to a shortage is more capable people, and that is a slow answer. It is also the only one that changes your position rather than just your pricing. Builders who train apprentices and retain experienced supervisors are less exposed when the market tightens, because they are not competing for the same scarce crews on the open market.
That has a direct commercial payoff. A builder with a stable internal team can price work with more confidence, hold dates, and avoid the premium they would otherwise pay for availability. It also makes the business less dependent on any single subcontractor deciding to take their crew elsewhere.
If you are supervising or running jobs in NSW, keeping your own knowledge current is part of the same logic. The guide to how NSW builder CPD works sets out what the regime requires and how it fits around a working week. Courses in contract administration and cost management are particularly relevant when the market is volatile, because that is when the drafting and the pricing decisions do the most work. You can see what is available in the PointCPD course catalogue, or start from the PointCPD home page for NSW builder CPD courses if you are working out where your own gaps are.
Two related articles are worth reading alongside this one. Labour shortages in residential construction covers the workforce side of the same problem. Subcontractor insolvency protection for builders deals with what happens when a trade under pressure stops trading, which is a real risk when margins are thin and costs are moving.
The bottom line
A skills shortage is a market condition, not a temporary inconvenience. It changes what trades charge, how long they will hold a price, and when they can start. None of that is within your control. What is within your control is how much of it you absorb.
Price the risk where you can, allocate it in the contract where you cannot, and keep your own team and knowledge base strong enough that you are not entirely dependent on the open market. Builders who do those three things tend to come through tight markets with their margin and their client relationships intact.
Questions builders ask
Why are my subcontractor quotes suddenly higher than last year?
When work is plentiful relative to the number of available crews, trades can be more selective and will price in a risk premium for committing to a fixed rate over a longer period. Their own input costs, including fuel, freight and materials, also move and get passed through. The result is a higher number and often a shorter validity period on the quote.
Should I accept a quote with a short validity period?
Accept it if you can make a decision within that period and you have diarised the expiry. If you cannot, treat the quote as indicative and ask the trade what they need to hold the number longer. Accepting a quote on the assumption it will still stand after it expires is how builders end up renegotiating from a weak position.
Can I lock in a subcontractor rate for the whole build?
You can try, but a trade who expects costs to rise will either refuse or build the expectation into the rate. A fixed price with no adjustment mechanism shifts the risk to the subcontractor, which is only useful if they remain solvent and willing to perform. Consider whether a defined adjustment mechanism is a better commercial outcome than a fixed number that nobody will honour.
What if a trade cannot start when my programme needs them?
That is an availability problem, and it is usually better to replan the sequence than to assume the trade will find a way. Ask what has to be true for their date to hold and build that into your programme before you commit to a completion date with the client. Discovering the constraint mid-build is far more expensive.
Does a labour shortage affect my obligations under the head contract?
Your obligations to the client do not change because the market is tight. What changes is the risk you carry if your programme depends on trades you have not confirmed. If a start date is genuinely constrained, raise it with the client in writing early so the programme discussion happens before it becomes a delay claim.
How do I stop losing good trades to other builders?
Pay on time, every time, and book them before you need them. Availability in a tight market is often won on relationship and payment behaviour rather than rate. A trade who trusts your payment cycle will take your call ahead of a builder offering slightly more but paying slowly.
