Althovjgh tho original (west <br />section^ 1. expeotad to carry less loading for the now construction, <br />soma sactxons of tha foundatisn aay lack uniform capacity and the <br />struetural cemponents appear to be leas aubatantlal than thoae <br />observed within the newer eas: addition. No would therefore <br />anticipate the installation c{ additional floor joists and supports, <br />ns already recoimended by the contractor. <br />tn our opinion, based on the iforemantioned teat snd observations, <br />tho eubgrada soils below the residence would be expected to meet or <br />exceed the losdbssring regultemants for the proposed construction. <br />We would however anticipate the addition of aoine atruoturel <br />elements, primarily within tht west section of the reaidonce, as <br />part of the new oonstruction.
