Law, Contracts and Regulatory Compliance
Core toolkit
Know the layers: statute (Professional Engineers Act, Building Control Act, Workplace Safety and Health Act, Fire Safety Act, Environmental Protection and Management Act, Energy Conservation Act), subsidiary regulations, approved codes of practice (a safe harbour, not immunity), and the contract. Contract basics: offer, acceptance, consideration, intention; express versus implied terms; variations, extensions of time, liquidated damages (a genuine pre-estimate), retention, performance bonds, indemnities and liability caps. Standard forms: PSSCOC for public sector works and SIA forms for private works - know who carries design risk and how notice and time-bar provisions operate. The Building and Construction Industry Security of Payment Act creates a statutory right to progress payments and adjudication, which is interim and binding until finally resolved by arbitration or litigation. Tort needs duty, breach, causation and damage; the limitation period is generally six years from the breach.
Traps
- Believing statutory approval of plans transfers design responsibility - it does not absolve the QP.
- Missing a notice or time-bar deadline and losing a valid claim.
- Confusing adjudication (fast, interim) with arbitration (final).
- Assuming a subcontractor's negligence removes the main contractor's or the PE's own duty.
Rule of thumb
Faced with any instruction that changes scope, ask before you act: Is it in writing? Does it change time, cost or quality? Who has authority to give it? Reply in writing within the contractual notice period - silence is usually read against you.
