Big Boatwork Projects and Execution Time

Power Train Install: Project Analysis
Power Train Install: Project Analysis.

I thought the power train install would take me a month. It took me three. The fact that I miscalculated the installation time by 200% got me to look seriously at how I had planned my time vs how I actually used it. I made a Gantt chart analysis of how the project evolved (the list of tasks is here). The Gantt chart (above) is splitted by sub-project, but also color coded by the type of practical work.

Two results stem out of the graph. First, the color orange dominates, which is all about parts delivery. In most instances, the project did not stall because of deliveries, as there were other sub-projects that could be pushed forward, but in the last days, the battery installation stalled the whole project because all other projects were done and because electric cables were missing. The chart emphasizes the critical importance of the supply chain in the project.

Second, assembling the engine bearers took a lot of time. Removing the older bearers took some time and equally all of the other aspects of the assembly. It was also my first big sub-project of the whole install, so I guess there is some learning time to be factored in. This may also be an argument for the purchase of custom made engine feets tailored to existing bearers (as Beta Marine USA provides). Engine bearers take time.
