Any damaged Silva Cell frames (or base and <br />posts) or decks shall be replaced. <br />To help avoid future disturbance of the Silva Cell system <br />the location: of the system should be accurately recorded <br />at the time of construction and incorporated into an <br />as -built drawing. <br />If possible register the location of the Silva Cell system <br />with the local One -Call utility locating program. <br />Accurately locate the limits of the Silva Cell system prior <br />to any future excavation in the area. (Some types of <br />underground utility locating equipment, such as ground <br />penetrating radar-, are capable of detecting Silva Cells <br />and may be used to locate the limits of the system. <br />Contact a professional utility locating contractor for <br />more information). <br />Utility warning tape/ribbon and locating wires can also be <br />incorporated into the system and are recommended. <br />tl U',ififfy <br />If the Silva Cell system is accidentally unearthed by future <br />excavation in the area, cease the excavation immediately <br />and consult the as -built drawings to determine the limits <br />of the system. <br />Using hand tools only, expose the impacted portion of <br />the Silva Cell system and carefully inspect the Silva Cell <br />frames (or base and posts) and decks for any signs of <br />clamage or cracking. <br />Replace any damaged Silva Cell frames (or base and posts) <br />or clecks and reconstruct any disturbed portion of the <br />system as per DeepRoot"s installation Guidelines. <br />The Silva Cell system supports vehicle loading <br />equal to 32,000 Ibs (14,500 kg) per axle, which <br />allows use in areas that accommodate 3 - 4 <br />axle vehicles such as those used for emergency, <br />delivery, and maintenance. Generally meets <br />AASHTO HS-20 (USA), CSA-S6, 87.5 and OBC <br />54KN (Canada), and BS EN 1991-1-1:2002 and BS <br />EN 1991-1-2:2003 (UK) loading standards when <br />used with standard paving profiles. <br />Throughout this document, where H-20 loading <br />is referred to, this is shorthand for the loading <br />standards described above. <br />To prevent damage to underlying Silva Cells, <br />ensure that machinery operated on the paving <br />above does not exceed loading as described <br />above. Do not operate any machinery over the <br />Silva Cell system without paving being in place. <br />Silva Cell Operation and Maintenance Manual <br />
