A-Spec – Including D-Spec, R-spec and O-Spec

Mitchell Shire Council in conjunction with other Councils has developed a specification document for the delivery of infrastructure data in a GIS-ready format. A-Spec is made up of a series of separate infrastructure specifications. These being:

  • D-Spec — Drainage data — including underground and open channel drainage, retarding basins and Water Sensitive Urban Design (WSUD) data
  • R-Spec — Road data — including road pavement, kerb, footpath and fire hydrant data
  • O-Spec — Open-space data — including active and passive recreation areas, park furniture and facilities

Unless otherwise agreed to by our Engineering Department, all new infrastructure created as part new sub-divisional development will require A-spec data files to be submitted to Council prior to the issuing of a Statement of Compliance for a subdivision that creates infrastructure that Council will manage.

Before the issuing of the Statement of Compliance or placing works on maintenance, you must submit to Council:

  • An electronic copy of the "as constructed" drawings in PDF and AutoCAD DWG file in GDA94-MGA Zone 55 mapping coordinates and the appropriate A-Spec files in (TAB or MID/MIF format) in accordance with the A-Spec Standard.
