We had Penhall Company out again today to core drill some important holes in our concrete walls. In order to close our remaining open trenches, we need to bring electrical services into the East Mechanical room. As well, we have to get our plumbing and electrical into the East Mechanical room from inside the house.
Theron Boulden, from Phil Murray Construction, was on site all day working on the 24 ft sliding glass doorway in the Living Room. Also, Theron continued working on the sliding glass doors to the Wine Dining and Wine Cellar. We believe the sliding glass door could be installed tomorrow (Wednesday).
Al and Nep worked on tweaking the framing in various locations, in order to accomodate the core drilling and other requirements. During the day, they ‘floated’ and helped with the core drilling (setting up the scaffolding), sliding glass doors (setting up the concrete cuts and actually cutting the concrete, and cutting recessments in the concrete walls for the Wine Cellar sliding glass doors).
Although Bryan met with Nathan Merrill, of American Ornamental Iron, he wasn’t able to order the FSB hardware for the front door. We’re still waiting to receive two quotes on the hardware. Bryan did, however, order the four Soss invisible hinges for the front door.
Core Drilling the Walls
We need to connect waste water drains and plumbing vents through the wall from the East Mechanical room to the soffit on the East side of the house. Thus, we need to have a penetration through the interior concrete wall to allow the pipes to pass through.
In addition, we need three penetrations through the exterior foundation wall in the East Mechanical room. One of these penetrations is for a 1-1/4 inch copper water supply pipe (from San Jose Water) and the other two penetrations are for data and electrical conduits.
Bryan reviewed the plans for the electrical and conduits with his father, John Mekechuk, when Bryan was in Edmonton last week. John, a Civil Engineer, thought the plans were acceptable in California and approved the design.
Coring through a vertical surface requires the identical technique that Bryan used when coring the shotcrete test panel (on 03/26/09). Although we considered doing the coring ourselves, engaging Penhall Company to do the coring brings their entire suite of equipment, including all the core bit sizes.
The technician from Penhall Company arrived earlier that the scheduled 10:00 am start time and left in his truck at 5:45 pm. He put in a good day of work.
