Subsurface Utility Exploration Services — Attachment A <br />POT HOLE UNIT RATES <br />Subsurface Utility Exploration Service Level* <br />Authorized Rate <br />Unit <br />Level A - Vacuum Exploring <br />01 -5' <br />$1,000 <br />5' -10' <br />$1,300.00 <br />Precise horizontal and vertical location of utilities obtained by the <br />actual exposure (or verification of previously exposed and surveyed <br />10' -15' <br />$1,600.00 <br />15' -20' <br />$2,200.00 <br />utilities) and subsequent measurement of subsurface utilities, usually at <br />a specific point. Minimally intrusive excavation equipment is typically <br />EA <br />used to minimize the potential for utility damage. A precise horizontal <br />and vertical location, as well as other utility attributes, is shown on plan <br />documents. <br />>20' 1 <br />$2,600.00 <br />Level B <br />Utility Locating <br />Information obtained through the application of appropriate surface <br />geophysical methods to determine the existence and approximate <br />horizontal position of subsurface utilities. Quality level B data should <br />$1.35 <br />LF <br />be reproducible by surface geophysics at any point of their depiction. <br />This information is surveyed to applicable tolerances defined by the <br />project and reduced onto plan documents. <br />Level C <br />Surveying <br />Information obtained by surveying and plotting visible above - ground <br />$0.50 <br />LF <br />utility features and by using professional judgment in correlating this <br />information to quality level D information. <br />Level D <br />Records Research <br />Information derived from existing records or oral recollections. <br />$100.00 <br />Hr <br />Professional Services are to be included with this item. <br />CITY HALL e 630 EAST HOPKINS ® SAN MARCOS, TEXAS 78666 e 512.393.8150 ® FACSIMILE 855.759.2846 <br />SANMARCOSTX.GOV <br />
