Parking Structure Foundation Pour Schedule Dec 10
The second major concrete foundation pour for the multilevel parking structure on the Santa Rosa Campus is scheduled for this
Saturday, December 10 from 7 AM to 7 PM. The same protocols and access restrictions are in place as they were last week to
ensure a successful activity.
It is still advisable, unless you have classes or business on the Santa Rosa Campus, to avoid accessing the college from
Mendocino Avenue, especially between Elliott Avenue and Ridgeway. We still anticipate considerable congestion between
Steele Lane and College during the construction hours, though it was managed very well last week.
Contractors, engineers, and college staff alike are very pleased with the significant and positive interest in this particular
project, and find that there’s a very active interest in the excavation work and foundation pours. The safest place to view
the construction activity of the parking structure is from the top of the east bleachers at Bailey Field looking down at the
construction site. This project is a real team effort, and we are quite pleased by the performance of our contractor, Wright
Contracting, Inc., and their subcontractors
.
Foundation Vision Strip is an Energy Loser
Concern that termites will crawl into buildings behind foam foundation insulation has led several states to modify perimeter insulation requirements in their energy codes.
North Carolina now recommends a 2-in. gap, or "vision strip," in the foam just below the sill plate so that pest control contractors can spot termite tunnels. For deep foundations, the code calls for another 4-in. gap below grade. Florida is considering a similar requirement. Georgia gives builders the choice of eliminating foundation insulation and increasing the insulation in attics from R-30 to R-38 or increasing wall insulation by R-1 to compensate. But according to Ned Nisson, editor of
Energy Design Update
, this option won't begin to offset the cost of eliminating foundation insulation. And "how do you increase wall R-value by R-1 anyway?" he asks.
A separate analysis by Oak Ridge National Laboratory researcher Jeff Christian concluded that the vision strip called for in the North Carolina code imposes a severe energy penalty. According to Christian, so much heat moves to the bare spot and escapes from the building that the remaining insulation is no longer cost effective. "If you include a vision strip, you might as well not bother putting any insulation around the foundation."
