State of Play: 2013/wk41

All kinds of stuff. Its the week to complete end of quarter BAS statement, with accountant coming in on Friday to check Quickbooks and finalise for submission.

Rewrote vba subroutines for wind pressures on free standing walls, the results prior to the rewrite seemed to be on the low side, given prior experience with AS1170.2:1989 compared to AS1170.2:2002. Oh! Seems further checks required, I keep forgetting we have AS1170.2:2011 as a pdf file. Anyway there were errors in the code and I fixed them, fortunately such loading is largely irrelevant, and back checks indicated other loads are still more critical.

Had problems with the network. Roy had moved around and sorted a large project directory, and the changes weren’t showing up when any other computer checked the shared drive. Dislike Windows 7. Seems his laptop was inadvertently set for offline file usage, but it was at no time apparent that access to the network was never real. After messing around for a while trying to see the drive via different pathways, gave up, did a google search on the problem, got a slight clue to the problem: tried it, fixed it. Time wasted, due to poorly designed user interface.

More hassles with suppliers of structural products, largely as a consequence of a failure for these suppliers to employ the services of an industrial product designer and get their products properly designed and documented. Development and building regulations are of minor importance to manufactured products, if suppliers don’t like the inconsistencies of city council approvals, then they should get their product designed properly. They employ web designers, so why not a industrial product designer? Their actual product design is more important than flashy brochures and a web site.

So ended up writing extensively on a specific product, however seems I need to write some general guidelines for design and development of manufactured structural products (MSP’s).

It is crazy that suppliers are pushing for software to carry out engineering calculations at point-of-sale, when they have put no real effort into the proper design and documentation of their structural product. The desire for the software is so that customer variations can be assessed. However unrestricted customer variations equals employ services of architect and engineer, not a salesperson.

Variations which are within the scope of salespeople at point of sale have to be based on a clearly defined building system, a product form with a limited feature set, but yet still highly adaptable. Sheds, canopies, balustrades, cafe screens, scaffolding, sports nets, water tanks and various other products supposedly supplied off-the-shelf, all require more design, than simply getting some engineering calculations, to meet Building Code of Australia (BCA) requirements.
