Cleaning Up

Removing demolition debris is the last step before construction begins

​Because of the configuration of the existing house on the lot and boundary constraints, almost none of the demolition debris could be directly loaded for disposal off site. Instead, most of it, including the infill CMUs and broken concrete, was carried to a dumpster parked on the street in front of the house by a skid-steer loader.

Crawlspace Excavation

Excavation for the addition began after the construction debris had been cleared. The original plan had been to excavate the new crawlspace, including the footings, by machine. But given the site constraints and the pending changes based on structural discoveries made during demolition, it made sense to use machines to scoop out the crawlspace, and leave the excavation of the footings until after decisions around the foundation had been settled.

The mini-excavator was used in a couple of hard-to-reach places around the existing bulkhead stair, then moved off site because there was no place to park it. The Bobcat was used for everything else: scraping away the root base, digging the crawlspace, and removing the excavated material, which was trucked off site.
