All required <br />permits will be provided by the City. <br /> Pavement coring will be accomplished during normal daylight workdays and hours, <br />with at least a minimum of 8 hours available per day for on-street work. Coring is <br />estimated to be completed within 1 day. <br /> Glacial till soils are anticipated at the site, which is a NRCS type D soil; therefore, <br />field testing to evaluate stormwater infiltration should not be required. No PITs or <br />EPA falling head (percolation) tests will be completed as part of this scope of work. <br /> Glacial till soils are anticipated at the site, which would likely provide enough <br />lateral capacity for use of WSDOT’s standard luminaire foundation design and for <br />shallow foundations or a gravel pad to support the proposed improvements. <br /> Traffic control such as flaggers, arrow boards, or other similar equipment will not <br />be required. Work zones are anticipated to be located within parking stalls or <br />landscape islands of the existing parking lot and can be delineated with traffic <br />cones. <br /> Utility locates will be comprehensive and accurate enough to allow reliable and <br />safe location of pavement cores. Vacuum extraction at the pavement cores is not <br />included. <br /> Coring locations will be field located using handheld GPS and measurement from <br />existing known features. Surveying of actual exploration locations is not included. <br /> The geotechnical explorations proposed herein will not be used to assess site <br />environmental conditions. However, visual or olfactory observations regarding <br />potential contamination will be noted. Analysis, testing, storage, and handling of <br />potentially contaminated soil and ground water (either sampled or spoils from <br />drilling) are beyond this scope of services. If contaminated soils and/or ground <br />water are encountered, the material will be properly contained on-site for disposal <br />as mutually agreed upon without additional cost to HWA.
