; , �. <br /> ' : • Monitoring of Crawlspace Stabilization RE&A Project No. 2828-15-058-ER <br /> Peterson Residence Mav 13, 2016 <br /> Smart Jack Installation <br /> Six (6) Smart Jack crawlspace stabilizer piers (SJ-1 through SJ-6) were proposed by RE&A for <br /> the crawlspace of the structure. A total of six (6) Smart Jacks (SJ-1 through SJ-6)were installed <br /> by LRE. <br /> The piers were installed in accordance with industry standards. For specific da.ta and pier <br /> locations as built, please refer to the attached As-Built Foundation Stabilization Plans (Sheet <br /> AB-1 &AB-2). <br /> After the final lift, pressure was applied and the system locked into place on their respective <br /> installation date. All of the piers were mechanically jacked to ensure that they all remained <br /> loaded. The crawlspace was stabilized through the pier installation process at those locations <br /> where the piers were installed. <br /> It is our professional opinion that with the above stabilization of the foundation the structure <br /> should continue to perform as designed. Should additional movement be observed, additional <br /> stabilization may be required. <br /> It needs to be noted that the above remedial process does not seal off the top of the karst <br /> limestone or minimize the ability of the overlying soils from raveling into the limestone, nor <br /> does it inhibit any shrink/swell activity in underlying highly plastic clay layers. Also, the Smart <br /> Jack installation only address the foundation system at those locations that were supported. <br /> 2 <br />
