Hello AllWe are in the process of reviewing our segmentation lengths recorded in our asset system for road/ kerb/ footpath assets.
I would appreciate your shared experiences regarding any rules strategies or developed procedures around segmentation of these asset classes, particular within an urban setting, while meeting accounting standards.ThanksJagath
I would suggest contacting the RMS (now TfNSW) transport library.
1) Segmentation based on Road surface type.
2) Segmentation of Kerb based on K&C Type.
3) Segmentation of roads based on Asset hierarchy (Arterial/Collector/Local
4) Segmentation based on segment length, minimum/maximum asset length (avoid 10m section, etc)
Hope this is useful :)
The issue that arises with using the seal as the segment is that this can change length depending on you works philosophy. A road, between two intersections may have more than one seal and in the future a reseal could replace all of these with one seal. You may then have to re-segment your road. Here at BRCC we now reseal, where practical, longer lengths capitalizing on the economy of scale. Our segmentation is now based on intersection to intersection or bridge or something fixed. We then have the seals as a child asset of that segment.
Parent level =ROAD A > BChild level = A: 0-100 A: 100-150The more rural road segments are again separated by a fixed feature (white fence post with green letterbox doesn't cut it anymore), this could be a bridge, significant bend trying to stay under 5km. Valuation and type data is stored at the child level for the seal but inspections and CAPEX is worked out at the parent level. Kerb & Channel and Footpath are usually done over the whole length as in most cases there is little variation. Road segmentation is then further based on the hierarchy and if its sealed or unsealed This aligns with the Road Management Plan. . I don't generally separate intersections and allocate them to the main road, usually defined by the traffic management there. Roundabouts however are considered separate segments. I know a few other places that do this too have a layer for value and a layer for defect inspections.It might sound a lot more difficult but believe me its not as you are going to map the seals anyway. It does add an extra level in your register but you only have to do this once and your history can stay intact.
