(There is no) Week four

Photo by Andy Dawson ReidOne of the episodes of my youth that turns out to have been somewhat less misspent than I feared at the time was the year that I wasted on devoted to a business studies degree course. Apart from the startling (to me!) realisation that business management was not going to be my forte, I thought at the time that I had not gleaned much of use from the experience. In retrospect – of course – this turns out not to have been the case.

One of the topics on the course that I did find to be of use later was a brief study of Critical Path Analysis (CPA). This fairly basic tool (developed in the 1950s for use on large US defence projects) provides a simple method of keeping projects on track by means of an analysis of the dependencies of the various component parts and the subsequent plotting of the eponymous ‘critical path’ through a multitude of processes to derive the optimum timeframe for delivery.

Though our deck project can hardly be compared in terms of complexity (or indeed of anything else) CPA techniques do provide some useful insights. Allow me to elucidate…

Our new deck has been framed, but nothing further has been done this week. Our contractor is rightly reluctant to lay the plywood deck on the frame until the vinyl installers are ready to apply the waterproof layer on top of it. A large flat surface of exposed plywood would rapidly absorb the sort of rain-showers we have been experiencing of late here in Victoria.

The vinyl installers can’t lay the vinyl until the old sliders (patio doors) have been removed. This is because the vinyl must be run under the new sliders in order that they effect a waterproof seal. The old sliders cannot be removed – somewhat obviously – until the new ones have been delivered (unless our whole main floor is to be exposed to the elements!).

The new sliders and windows are now on order, but that could only happen once the demolition had been finished such that the manufacturers could accurately measure the apertures.

Finally, the cabling for lighting and sockets, the deck railings and glass panels, and all of the other bits and pieces of finishing can only be applied once the deck itself has been completed.

Ergo – a hiatus…

Nothing to see here folks (quite literally with regard to the current view from our drawing room – see image above!).
