See Fine Homebuilding magazine January 2003 No. 152 pages 76-79 "A Stone House in Two Weeks" by Thomas J. Elpel.
This article describes the construction of a house built with tilt-up concrete construction methods. The author's brother Nick Elpel built a house by laying stones flat on the ground, putting a bentonite clay and sand mix between the stones to form recessed mortar joints, placing 1/2 inch rebar spaced 1 foot apart, and pouring a concrete slab over the whole thing, locking the stones in place in the walls. He formed quoins at the corners using foam cores which were later removed to provide a place for vertical rebar and grout to hold the wall sections together. Window and wall openings were included in the form work.
The wall sections were lifted into place with a construction crane. The corners were grouted with rebar in place. The wall sections were erected on concrete pads. Then the footers were poured under the wall sections.
The house is rectangular with gabled ends in a storey-and-a-half style. It has a smaller gable on the front perpendicular to the main axis of the house. The author reports that the interior was framed with conventional framing to provide space for insulation and utilities. The roof is conventional framing. It appears to have a metal roof. Windows are framed with concrete frames.
The article states that the builder used crane pick up coil inserts from "(Dayton/Richmond Condrete Accessories; www.daytonrichmond.com ; 800-745-3700)... as well as inserts for attaching temporary bracing. Dayton Richmond's 'Tilt-Up Construction Handbook' guided the work... Another source for information is the Tilt-Up Concrete Association (www.tilt-up.org)."
