Pence/Kelly Construction, Inc. continually strives to p~ovide awners' with <br />the highest quality workmanship possible. <br />The contract documents calied for a specified strength, and ditl not specify an <br />aggregate size. The 3/8" aggregate mix was submitted and approved for use by <br />Tim Terrich to meet the strength requirements for the columns; <br />The 3/8" aggregate mix was selected over the'/." mix for the cblumns even <br />though the 3/8" aggregate mix cost Pence/Kelly $9.00 more p~r yard than the'/." <br />mix. This cost concession was made because of the tight rebar spacing in the <br />cc~lumns; the 3/." mix would have increased the risk of inadequate vibration during <br />pl3cement and resulted in finished columns with rock pockets. : <br />Pence/Kelly provided the best mix design for the job <br />'ncerel , <br />1 <br />bave Hays <br />Project Manager <br />Cc: Leonard Lodder, Billy Wasson, John Whit#ington, Tim Terrich <br />
