And the later addendum:
They ended up digging the trench right up to our basement wall, next to the porch concrete, cut yet another hole in the drywall, and punched through the cinder block wall in order to install the new pipe. They knocked off of work as of 1945; they'd been at it since about 0900. Resuming around noon today. Looks like the installation is about half done, but then there's the mandatory inspection by WSSC, and presumably only after that can they refill the holes. Possibly no water until Friday.
