Surveyors are required during the construction process of most infrastructure. Surveyors provide the link between the design plans and the 'real world'. Surveyors interpret the design plans and provide innovative ways to mark the information onsite to allow the infrastructure to be constructed. Construction surveys may include multi-storey buildings, roads, bridges, and any other structure. Surveyors also provide conformance reports and as-built reports during the construction process and for final certification. Monitoring surveys are also carried out by surveyors to monitor the disturbance or movement of a structure such as a dam or building.
