DAJDESIGN <br />ARCHITECTURE, INTERIORS <br />Recommendations: <br />1. The foundation walls (including the perimeter crawlspace/porch walls and interior basement CMU <br />walls) should be replaced with a new concrete foundation at either a basement or crawlspace depth <br />below frost, or a combination of basement and crawlspace depths. New foundation walls should be <br />designed by a licensed structural engineer and supported with proper footings. <br />2. A new foundation should be set high enough to allow for proper drainage away from the foundation as <br />prescribed by a geotechnical engineer. To pour a new concrete foundation, the house will need to be <br />temporarily lifted or moved to a temporary location by a licensed house mover. The location of the <br />house on the site should not vary from the current, historic location. <br />3. Alternatively, the existing crawlspace foundation walls and basement retaining walls could be <br />v� reinforced or partially replaced, but this would be at a greater cost and with a less desirable outcome <br />than entirely replacing the foundation. The following outline a few options to evaluate and reinforce <br />the existing foundation: <br />a. Bracing should be added to laterally support the CMU walls to help in retaining the <br />crawlspace soil. In addition, steps should be taken to prevent water infiltration through the <br />CMU wall. <br />b. Grouting of the CMU walls should be completed especially at the locations where main floor <br />beams are bearing on the CMU walls. <br />c. The footings were not visible during the observation and should be verified and evaluated <br />prior to any remodel or new construction. Coordinate all findings with a licensed structural <br />engineer. <br />d. Continually monitor the main floor walls for signs of foundation distress such as cracking or <br />improper door operation. Wall cracks were not observed within the wall finish on the main <br />level. If signs of cracking are detected, these areas should be evaluated by a licensed <br />engineer and repaired as needed. <br />4. New footings are likely needed to support the point and distributed loads from the roof and floor <br />framing as specified in the recommendations below. New foundation support below any new beam <br />and posts supporting the floor and roof framing should be coordinated with a licensed structural <br />engineer. <br />5. Foundation wall and crawlspace insulation should be added to achieve an R-value as close as <br />possible to current code standards. <br />700 PINE PAGE - 14 <br />
