Construction surveyors make measurements and recommendations to engineers, architects and other professionals at all stages of construction. A few items that may be laid out or staked include: utilities, roads, buildings and much more! After projects complete, surveyors come back and verify the locations verse the plans.
While other surveys provide details about the parcel of land itself, an as-built survey provides details about structures being built or recently completed upon the property. As-built surveys can be ordered at various phases of larger building projects to ensure construction is progressing according to plan, but a final as-built survey will be needed to verify completed work and ensure that the structure satisfies requirements of local government authorities.
