<br />c <br /> <br />c <br /> <br />c <br /> <br />City of Sunny Isles Beach: Special Inspection Services <br />RFO No. 11-07-11 <br /> <br />URS staff are highly experienced in performing and/or reviewing <br />the ancillary CAPWAP analysis of PDA data generated by the <br />PDA testing equipment. This PDA testing and CAPWAP analysis <br />and/or review work of same would be performed under the <br />direction of Mr. Micheal Sharp, PE as the technical Special <br />Inspector for such piling installation. Mr. Sharp is extensively <br />experienced in such work and presently provides such PDA <br />testing services on FDOT Districtwide PDA testing contracts based <br />out of the URS Tampa, FL office. <br /> <br /> <br />In addition to the PDA testing, it will be necessary to monitor the pile driving operations and to record the pile <br />driving resistance or blow counts per foot of driving during installation. URS staff have FDOT Pile Driving <br />Certifications necessary to provide these services. <br /> <br />Vibration and Settlement Monitorinq Services - During pile driving activities, it is common for URS to <br />provide Vibration Monitoring and Settlement monitoring surveys during piling installation activities primarily <br />when drive pilings are being installed. URS owns and operates four ( 4) vibration monitors as well as survey <br />level and rod equipment needed to provide such monitoring services. <br /> <br />Vibration monitoring criteria normally requires that vibrations imparted to adjacent structures not exceed a <br />vibration level greater than 0.5 inches/sec. Experience indicates that this vibration level is capable of being <br />felt by adjacent landowners and occupants thereof and may be sufficient to cause minor hairline cracking of <br />older more lightly reinforced structures - particularly where block construction was used in the building. <br />Depending on the location of the pile driving, distance to the adjacent structures and nature/age of the nearby <br />adjacent structures, lower vibration monitoring criteria may be appropriate to be specified to avoid or <br />minimized minor damage to adjacent buildings as well as to minimize complaint calls to the City. <br /> <br />Geotechnical Drillinq and Samplinq/Laboratorv Testinq Services - As previously indicated, URS has <br />been providing geotechnical design services to numerous high rise projects in the Sunny Isles Beach area for <br />over 15 years. During this period, URS has utilized the geotechnical drilling sampling and laboratory testing <br />services of Vertical V Southeast Inc. (i.e. formerly Bureau Veritas - North America Inc. - formerly Intercounty - <br />USL Laboratories Inc.) on the majority of high rise projects in the area. <br /> <br />Correspondingly, URS will continue to utilize Vertical V <br />Southeast Inc. drilling equipment and laboratory testing <br />services based out of their North Miami Beach Facility near <br />Interstate 95 and the Golden Gate Interchange. <br />Additionally Vertical V will provide field inspectors staff for <br />sampling and testing of construction materials on an as. <br />needed call out basis <br /> <br /> <br />......"., <br />. ~a" <br /> <br />2-23 I P :0 E Co <br /> <br />URS <br />
