Contract scope should identify
- drawing revision
- site location
- approvals responsibility
- engineering responsibility
- design standards
- dimensions/materials
- restraint system
- gangway
- electrical/water
- transport and lifting
- installation
- certification
- defects period
- warranty
- exclusions
Payment protection
Avoid paying nearly the entire contract value before site installation unless ownership, insurance and inspection of off-site goods are clearly addressed. For large projects use milestone evidence and consider retention or bank/security mechanisms appropriate to project value.
Warranty traps
A "20-year structural warranty" can exclude floats, deck, fenders, finish, corrosion, storm, impact and unauthorised electrical systems. Read:
- covered components
- start date
- labour/freight coverage
- transferability
- inspection/maintenance conditions
- storm/flood/cyclone exclusions
- commercial-use exclusions
- corrosion exclusions
Variations
Waterfront works commonly encounter latent conditions. Require unit rates or a documented variation process for extra pile length, refusal, crane time, barge time and approval redesign.
The contract is the product
With a pontoon, the contract decides what happens when something goes wrong, and something eventually does. A structure that is built well and documented badly is worth less than one built adequately with complete records, because the records are what you have when a defect appears three years later.
Terms worth settling before the deposit
- Scope: precisely what is included, and explicitly what is not — approvals, engineering, piling, services, access works, site restoration, removal of the old structure.
- Deposit: how much, what it secures, and what happens to it if approval is refused or a condition changes the design.
- Payment stages: tied to milestones that can be verified, not to dates.
- Program: the delivery window, what causes it to move, and what happens if it does.
- Approval risk: who applies, who pays for conditions, and who carries the cost of a redesign.
- Variations: how they are priced and authorised, in writing, before work proceeds.
- Defects liability: how long, what it covers, and how a defect is reported and resolved.
- Warranty: separate from defects liability, with its own term, exclusions and maintenance assumptions.
- Certification: who provides it, when, and in whose name.
- Retention: whether an amount is held past completion, and what releases it.
What to check in the warranty document
- What is covered: structure, floats, deck, hardware, coatings, services — each may differ.
- What voids it: maintenance failures, modifications, overloading, storm events, use outside the stated purpose.
- What maintenance it assumes, and whether that regime is documented and achievable.
- Whether it is transferable if the property is sold.
- Who honours it if the builder ceases trading, and whether any component warranties sit with manufacturers.
Where buyers get hurt
- Paying a large deposit against a quote rather than a contract.
- Accepting "engineering included" without seeing who certifies and what is certified.
- A warranty that assumes a maintenance regime never handed over.
- Variations agreed verbally on site and disputed later.
- No retention and no leverage at the point defects are found.
Questions buyers ask
Is a quote a contract?
A quote sets a price. It rarely sets scope, program, payment stages, defect obligations or risk allocation, which are the parts that matter when there is a problem. Ask for a contract.
What is a reasonable deposit?
That is a commercial question, but what it secures should be stated: materials ordered, a production slot, design work performed. A deposit that buys nothing identifiable is a risk rather than a commitment.
