Contract clauses, one at a time

Good commercial relationships run on small tolerances: a late payment accepted, a missed report forgiven. The waiver clause lets a party be reasonable today without being told next year that its patience rewrote the contract.

In Australian construction and commercial leasing, an unconditional bank guarantee is the usual form of security. It is as good as cash to the holder, so the clause's real job is to control when that cash can be taken.

A collateral warranty gives someone outside the building contract, typically a funder, a buyer or a tenant, a direct contractual claim against the builder or designer if the work is defective. In the UK it is often required by the main contract, and its terms, especially net contribution, caps and assignment, decide how valuable it is.

Almost every building job changes between the drawings and handover, and variations are where most construction money disputes begin. A clause that fixes the paperwork and the pricing method before work starts turns each change into a calculation rather than a negotiation held after the concrete has set.

The defects liability period is the contractor's right to fix its own work at cost as much as the owner's right to have it fixed. It also decides when retention and security come back, so its dates matter to cash flow long after the last trade leaves site.

Reasonable skill and care asks whether the designer did a competent job. Fitness for purpose asks whether the thing works. The difference matters most when something fails despite everyone following the standards, as the UK Supreme Court showed in MT Højgaard v E.ON.

Nobody sees under the slab or behind the wall until the work starts, so this clause allocates the one risk neither party can fully price. Contractors who miss its notice deadline often lose a claim they would otherwise have won.

Drawings say what to build, but this clause says how well, and it is the benchmark every defect claim is measured against. Naming the code, the standards and the manufacturer's instructions turns a vague promise of quality into something both sides can check.

Main contractors would like to pass the risk of a slow paying client down to their subcontractors. For construction work in the UK, Parliament decided in 1996 that they mostly cannot, and replaced pay when paid with a fixed timetable of due dates and notices.

A performance bond moves the risk of a contractor's default onto someone with deep pockets. The most important word in it is not the amount but whether it pays on demand or only once default is proven.

Practical completion is the date the contractor stops paying delay damages, the defects period starts and part of the retention comes back, so both sides watch it closely. A definition that relies on the word practical alone leaves each side free to argue its own meaning at the moment money changes hands.

Under the model WHS laws a construction project has only one principal contractor, and the role carries duties that cannot be met without real control of the site. A clause that appoints a builder in name while the owner keeps control fails in the way that matters most, on the day of an incident.

Construction runs on progress payments, because a contractor cannot fund months of labour and materials until handover. The clause sets the rhythm of that cash, and in every Australian state it works alongside security of payment laws that override anything in it restricting a claim.

When timber and steel prices jumped in 2021 and 2022, many fixed price home building contracts became loss makers overnight. Rise and fall clauses are the builder's answer, and state home building laws are the owner's protection against them being used without limit.

Most arguments about extras are really arguments about scope, because a price only means something once everyone agrees what it buys. Writing the exclusions down is what stops a homeowner assuming the tiles were included and a contractor assuming they were not.

Security of payment laws give contractors and suppliers down the chain a fast route to progress payments, and nobody can contract out of them. The clause matters because missed deadlines under those laws cost real money, and a contract that states the dates and service addresses plainly keeps both sides on time.

A contractor cannot start, and the programme cannot hold, if the site is not available on the day it was promised. On occupied sites such as schools, hospitals and aged care homes, the access clause also protects the people who live or work there while the builders are in.

When a developer's finance is at risk, its lender wants to be able to take the developer's place in the building contract rather than watch the project stop. When an outsourced service fails, the customer wants to step in and fix it. Step in rights do both.

Construction contracts give contractors rights to more time and money when something outside their control happens. Time bar clauses add a catch: say so promptly, or lose the right. Courts in England have repeatedly held contractors to clear ones.

Safety duties under Australian law cannot be handed away by contract, but a contract can make sure each business on site knows what it must do and when. That clarity is what stops a crew starting work at height on a morning when nobody has handed over the safe work method statement.

An instalment loan is a promise to pay over time. The acceleration clause is what turns a missed instalment into a demand for everything, and the notice and cure periods around it decide how quickly that can happen.

A down round already hurts founders, and the anti dilution formula decides how much more of the company moves from them to earlier investors. The gap between the two formulas can run to hundreds of thousands of shares, so this is a clause where the arithmetic matters more than the wording.

A capital contribution clause records who puts what into a partnership or joint venture and on what terms: the amount and form, the date, the agreed value of anything other than cash, whether further calls can be made, and how capital is returned. It is the clause partners argue about first when a business is sold or one of them leaves.

Selling a company does not assign its contracts; the company is still the party. That is exactly why customers, suppliers and joint venture partners write change of control clauses: they want a say if a competitor ends up owning the business they deal with.
