Conclusions & RecommendationsConclusions & Recommendations

The lateral force resisting system can be safely reduced from 10 frames to 6 frames for a estimated savings of $18,000.

A drilled pier foundation system is not a cost efficient replacement for the spread footing system.

The Vierendeel truss is extremely effective and efficient for carrying significant loads over a large span.
