State of Play 2018/wk42

Health So went to see the cardiologist in Wallaroo. Nurse measured weight, height and blood pressure and also took ECG, after which I saw the cardiologist. Dad drove me there from Maitland, mum and dad went shopping whilst I was at the doctors, on the way back they suggested we visit centrelink. So did that. […]

More Comparing Calculation Tools

Before continuing with Building a Structural Engineering Design eWorkbook, I thought I would backtrack and extend the comparison of calculation tools.  In the first article I compared some  computer based calculators,  Computer Algebra Systems (CAS) and simple scripting languages. ATCalc Calc98 SMath (cf. MathCAD) FreeMat (cf. MatLAB) Python VBScript (WSH) JScript (WSH) FreeBasic LibreOffice Calc […]

Work Measurement and Time Study

Amongst other things, being an industrial engineer (MIIE(Aust) resigned 2014) I don’t dismiss time casually, so when I say we don’t sell time it doesn’t mean we don’t pay attention to time. When conducting a time study, it is typically done using a decimal minute stopwatch (if you can find one in SA), so instead […]

Learning WordPress Customisation: Themes and Plug-in Development Part 1

My foray into wordpress theme development. Introduction: the need The need stems from the fact that the wordpress ecosystem is highly inefficient and wasteful. When comparing blogger versus wordpress.com, it seems like it is a lot easier to change the layout and colours of a blog on blogger than wordpress.com. WordPress seems to be built […]

Wind Classification Maitland, Yorke Peninsula and Surrounds

Introduction to Wind Speed Classification In Australia we have two wind loading codes AS1170.2 and AS4055. The latter (AS4055) whilst it refers to housing, was created to provide a simplified classification system for use with manufactured structural products (MSP’s). It is neither practical nor economical to use AS1170.2 directly to design a structured product. The […]

Structural Certification is not a view and stamp exercise

Some people seem to think that structural certification merely comprises of viewing drawings of a proposal and then “rubber stamping” the drawings as structurally adequate (eg. they have turned up at the office, and expected we stamp and approve there and then.). Certification seems to be sought to save time and money. The process can […]

Collapse: Household Decks and Balconies are not Designed for Parties

So at the beginning of the year I was working on a project which whilst in the scope of the South Australian development act, and potentially the SA Building rules, it was otherwise beyond the scope of the Building Code of Australia (BCA) and National Construction Code (NCC). This in turn led me to take […]

Comparing Calculation Tools

As indicated in previous post I’ve been considering whether to move away from spreadsheets for my calculations. I have previously discussed the use of MathCAD and similar software versus the use of spreadsheets on my personal blog in the post: Electronic Calculations (eCalc’s) . In the previous article my focus was protesting against those who consider […]
