The model was created and animated with SketchUp, output to a series of .png and put together in VirtualDub and output as .mp4 using this hack. The animation was then imported into VSDC Free Video Editor for post-production.
Enjoy the animation!
Like usual I couldn't claim the construction process depicted in the animation is 100% by-the-book as there are a lot of factors affecting the construction of a certain structure on site. Constrained by small working space -- it's most certain the excavated pit on site will never be as spacious as the one shown in the animation -- sometimes it's easier to bind those base rebars into a "basket" before unloading them into their formworks. Likewise for stump reinforcement.
