Frequently asked questions
What does a civil engineer do on a development project?
Civil engineering covers the works that make land usable: earthworks and site grading, roading and access, stormwater, wastewater and water supply reticulation, and the associated erosion and sediment control. On a development the civil engineer prepares the engineering plans for resource and building consent, obtains engineering plan approval from the network operator or council, and provides construction monitoring and the completion certification needed for section 224c or title release.
What is engineering plan approval?
Engineering plan approval, often abbreviated EPA, is the approval a council or network operator gives to the detailed design of public or vested infrastructure before construction starts. It is separate from resource consent and from building consent, and it is assessed against the relevant code of practice or engineering standards. Allowing time for EPA in the programme is one of the more common causes of delay on subdivisions.
Do earthworks need consent?
Often yes. District and regional plan rules set thresholds for the volume and area of earthworks, the proximity to watercourses, coastal margins and overland flow paths, and work on slopes, above which resource consent is required. Even where earthworks are permitted, erosion and sediment control obligations still apply, and fill that will support future building work needs to be placed and tested as engineered fill if it is to be relied on.
