Definitions
Chipseal surfacing supervisor refers to a person who works in the chipseal surfacing
industry with site responsibility for large, complex jobs, and/or oversight of several
smaller jobs at a number of locations simultaneously. The chipseal surfacing
supervisor has practical knowledge of contract law and contractual issues; detailed
understanding of chipseal surfacing construction, contract documents and
specifications; and, in a chipseal surfacing context, has defined responsibilities for
planning and organising construction work, managing site safety, issuing instructions
to forepersons and suppliers, team performance and productivity, contract
documentation, and quality assurance, with authority to manage operations and
make decisions relating to chipseal surfacing works.
Company procedures refers to all documented policies, procedures, and
methodologies of the candidate’s employer at the time of training including but not
limited to those relating to health, safety, environment, quality, and operations.
Maintenance period means the period of time from the removal of temporary speed
restrictions until final acceptance by the engineer during which time the contractor
may have corrective action obligations specified in the contract specifications.
Protection period means the period of time from the completion of rolling until the
removal of temporary speed restrictions during which time the contractor may have
corrective action obligations specified in the contract specifications.
