Foundation work continues & the 1st lumber order arrives

The mason has poured the foundation footing at the rear addition and laid the CMU that the wood floor joists and exterior stud wall will rest on. The slab under the crawl space (what is called a 'rat' slab) is to be poured today. The elevation of the slab will be about 2 feet below the bottom of the floor joists. This will give the subs adequate space to work in (kitchen plumbing, insulation, etc) along with a nice clean, hard surface to move around on. Closed-cell 'Bio-Based' spray foam insulation (made from soy) will ultimately be placed between the floor joists to insulate as well as create a vapor barrier between the crawl space and the interior of the house.


































Also, the first order of FSC (Forest Stewardship Council: http://www.fscus.org/) certified lumber (2x4s, 2x6s, and T&G plywood), along with the engineered floor joists, arrived this morning. All of the lumber in the project will be FSC certified and sourced through Green Depot (http://www.greendepot.com/) in north Philly. The GC (who will be framing the house) will have the first floor joists in place and the plywood decking laid down for the addition by the end of the day today!
