Contract and Project Management: Time, Money and the Architect's Role
What this domain tests
Procurement choice, the architect's contract administration role, and the mechanisms that move time and money. Questions ask you to value a variation, decide an extension of time, identify where a risk sits, or say what the architect may and may not certify.
Forms and roles
- Private sector projects commonly use the HKIA Standard Form of Building Contract, with the architect as contract administrator and certifier.
- Public works use the General Conditions of Contract, or NEC forms adopted by the Development Bureau, which move risk management towards the project manager and a foreshadowing, early-warning model.
- The architect certifies. The architect does not arbitrate and does not give final decisions on disputes.
Time and money mechanisms
- Variations are valued at bill rates where the work is of similar character and executed under similar conditions; otherwise by fair valuation. Omitted work is valued on the same basis.
- Extension of time needs a contractual ground, notice within the stated period, and causation shown on the programme.
- Loss and expense is recoverable only where the contract provides a ground for it; time and money are separate entitlements.
- Liquidated damages must be a genuine pre-estimate of loss, not a penalty. They run from the adjusted completion date.
- Retention, performance bond, defects liability period and the final account close out the payment trail; practical completion starts the defects liability period and changes insurances.
Worked example
A contractor claims ten days and cost for typhoon and heavy rain. Reasoning: check the contract definition and thresholds for inclement weather, whether notice was given in time, and whether the event is an excepted risk. Inclement weather typically supports time but not money unless the contract expressly provides otherwise. The architect should certify the extension with reasons and state that no loss and expense is certified, relying on contemporaneous site and weather records for the length.
Traps that cost marks
- Certifying an extension of time without checking the notice provision.
- Treating every client instruction as a variation.
- Confusing liquidated damages with a penalty or with general damages.
- Stepping into an arbitrator's role when a dispute emerges.
