SHEET NO. <br /> S 1 809 07-1 <br /> 7111\ <br /> 7215 Juniper Dr, Everett, WA <br /> PROJECT P <br /> LONGITUDE SUBJECT Foundation Stabilization/Jacking <br /> ONE TWENTY° <br /> ENGINEERING&DESIGN BY CMH DATE 09/11/18 <br /> Scope/Objective: <br /> To determine the required pile spacing and geometry to stabilize and lift(where required)the existing structural foundation. <br /> These findings have been based upon the calculated strength of the existing foundation system and the current vertical <br /> loading from the existing structure above (based on as-built assessments). <br /> The Ram Jack West proposed pile layout can be found in the following pages with structural recommendations based <br /> upon the findings of L120 Engineering& Design. <br /> Note that cosmetic damages to rigid wall coverings/members and siding are expected during a foundation lift. Such <br /> cosmetic damages/cracks are to be repaired by others following the completion of the foundation stabilization and lifting <br /> and are not included in the structural scope presented here. <br /> It should be further noted that, per Ram Jack West,the stabilization effort will be limited to the perimeter support <br /> systems/continuous footings.The interior crawl-space support system for the first floor will be lifted with the use of some or <br /> all of the following: longer support posts, adjustable post-base hardware, and/or the addition of taller wood support <br /> members. Settlement in these interior support areas shall be monitored and further adjustments shall be made if <br /> necessary. <br /> Structural Summary: <br /> -The foundation of the residence consists of continuous cast-in-place concrete footings. Below the cast-in-place concrete <br /> footings, piles are to be spaced at a distance no larger than 8'-0"on-center at the locations indicated on the attached Level <br /> Survey. <br /> -A maximum allowable loading of 1,500 plf was utilized in this analysis. This was determined through inspection of <br /> building geometry and conservative span/tributary loading assumptions based on standard construction practices <br /> - The following load values represent the maximum expected pile loads for the indicated spacing. Ram Jack West to <br /> provide pile and equipment assemblies with ultimate capacities equal to or greater than the indicated load values. <br /> Exterior/Perimeter Piles @ 8'-0"o.c 18 kip minimum vertical capacity(ultimate) <br /> - As determined by Ram Jack West,the site appears to have no lateral (horizontal) displacements or concerns. As such, <br /> the analysis and recommendations presented in this report have been strictly limited to vertical stabilization/jacking. If <br /> lateral movement is observed or expected, additional structural analysis will be required. <br /> - Structural recommendations contained in this package are based on site photographs dated September 7, 2018, <br /> provided by Ram Jack West.To the knowledge of L120, a geotechnical investigation was not performed on this site. <br /> Consequently, all structural recommendations assume adequate soil conditions to obtain the required pile capacities. <br /> Refer to the following pages for pile and connection specifications. <br /> L120 ENGINEERING&DESIGN <br />
