Reinstate Excavation and Pavement Surfaces in Site Operations Gas Network Construction
Overview
This national occupational standard defines the competence involved in interpreting instructions, planning, organising and adopting safe working practices for preparing and carrying out the reinstatement of excavations and the surfaces of highways and footway pavements following site operations, by use of the appropriate sub-grade, sub-base and road-base materials and by suitable selection of surface materials including cold-lay bituminous and modular surfaces.
This standard is for those responsible for operations during gas network construction activities. These activities will usually include the leadership and direction of the members of a team and decision making regarding the approach to take when undertaking the work.
This standard consists of four elements:
- prepare for reinstatement of excavation and pavement surface in site operations
- carryout reinstatement of excavation and pavement surface
- use and communicate data and information
- resolve problems which arise from the reinstatement work
