Smart Parts: Cable Trench!

I briefly touched on this in the latter part of my previous post; referring to the inclusion of additional information to the 3d model parts that facilitates the requirements for other purposes.

We studied the historical layouts for the sub station below ground works and realized that Cable Tenches in particular were not given a great deal of thought. It just seemed to be a case of developing a routing and fitting the Trench units accordingly even if this meant that there was a lot of “non-standard” sized units.

We recreated these same routings using as many standard lengths as possible; by manipulating the cable exit points marginally we were able to do this without too much effort. The main reason for doing this is simply that the site will receive lorry loads of this stuff which could be time intensive for the site guys to trawl through the stacks of trench items just to find the correct parts to suit the drawing layouts.

The other reason is cost. The off the shelf units are available in standard lengths and any variation will require additional work for the vendor in cutting and sorting to suit the client requirements. In the overall scheme of things the additional costs may be inconsequential but if this can be negated with a small amount of effort then this is something we should try to achieve. Collectively, in conjunction with handling time saved on site the overall costs benefits could actually be quite significant.

We did something similar for the Cable Ducts as well; which managed various stacked configurations:
