AVAVA Systems Proves Speed of New Framing Technology

A newly patented construction technology was demonstrated last Friday in Berkeley, California in the form of a third-story addition to an existing single family house. What would have taken 2-3 days was completed in less than two hours.

On Friday, July 23, 2010, AVAVA Systems partners David Wilson, Michael Kozel, and Robert Crivinar demonstrated their patented new construction method by adding a third story to an existing house in the hills of Berkeley, California. The 500-square-foot addition was framed from start to finish in less than 2 hours. Architects and contractors witnessing the construction were astonished by the speed and ease of the new technology, in addition to the precise geometry of the final structure.

Other than the sounds of typical construction banter with some less typical laughter, the occasional power screwdrivers were the only noise heard during the two-hour process. The horizontal I-joists were lifted into place, followed immediately by two of the patented joist-locks™ and two vertical I-joists until there were a row of 20 or so interlocked wood frames. Two thin steel rods were then threaded through the joist-locks™ at each upper corner and tightened together with steel washers and nuts, locking the structure together. The result was a 500-square-foot open-ended room with perfectly square walls and a smooth flat roof, ready to be covered with a plywood exterior.

Asked how this construction compared to traditional residential wood framing, Mike McCurdy, the Project Contractor, responded “the same amount of framing in traditional 2x stud framing would have taken two to three days.” McCurdy went on to say, “I would love to do this type of construction again anytime.” Architects who were on hand to witness the first real world application of the new technology were also very impressed with the rapid and simple construction, with a touch of disbelief: “It seems that everyone involved with putting up the frame was having such a good time, I wanted to join in the fun.”
