Typical procedure in the inner city build of a laned parcel. Get the house up and the sewer installed into the street. Get the gas company to trench and pipe gas to the house from the alley. And then struggle to get the garage built so that a mast and submeter can go on the garage and then a trench and line fed to the main panel in the basement. Once complete, the builder can do two items of considerable importance. Energize the panel for lights and turn on the furnace. After we get to drywall no further work can be done without heat inside. And the heat needs to be consistent and humidity managed all winter, a real challenge to accomplish.
