The recommended allo���ablc lateral capaciry of aueercast piles (applied <br /> at the pile top), assumes a fixed liead condition. <br /> l TUe lateral capacities presented in Table 1 above were determined assuming 0.5 inch of <br /> detlection at the pile top with the pile tops tised to prevent rotation. A factor of safery of 2 <br /> was applied to die allowable lateral capacities. <br /> � 9.3 Pile Inspcctions <br /> I The actu�l total len!_di of each pile may be adjusted in the field based on required capaciry and <br /> conditions encuuntered durine drilling. Since completion of the piles takes place below <br /> � ground, the judgment and experience of the eeotechnical engineer or his field representative <br /> must be used as a basis ibr detennining thc reyuired penetration and acceptabiliry of each pile. <br /> ConsequenUy, use o( thc presented pile capacities in the design requires that all piles be <br /> � inspccted by a qualitied representative from our (irnt who can interpret and collect the <br /> installation data and obscrve the contractor's operations. Tl�e geote�hnical engineer, acting as <br /> the owner's ti�ld representative, would determine the required leneths of the piles and keep <br /> � records of pertinent installation data. A tinal summary report �aould then be distributed, <br /> follo���ing completion of pile installation. <br /> � l0A LATER:IL \VALL PRGSSURCS <br /> ( All backlill Uchind retaining ��alls should Ue pl�ced as per the recommendations for structural <br /> till as descrihe� in Sectiun 3.0 of this report, and as d�scribed belo���.
