CG Engineering provided the structural design of a 3,000 square foot, third-story addition to this two story approximately 6,000 square foot residence. The existing house has one story of concrete construction and one story of wood construction. Addition of the third floor significantly increased loading to the existing foundation.
Wherever practical, new columns were added through the concrete slab down to the foundation and new footings cut in where new loads came down on the foundation. CG provided onsite field investigation of foundation conditions and slab and beam reinforcing.
