Upon completion of each pavement core exploration, the pavement is to be patched with aquaphalt cold. No hot mix asphalt patching is proposed, and additional costs will be required if the City requires different patching materials.  Generate Core Logs and Assign Laboratory Testing: HWA will generate summary core logs for each pavement core and associated hand exploration. Samples retrieved from our explorations will be sealed in plastic bags and taken to our Bothell, Washington laboratory for further examination and testing. Selected samples will be tested to determine relevant engineering and index properties. Depending on the type of soils encountered, laboratory testing performed may include moisture content, grain-size distribution, and/or Atterberg limits test. Soil and laboratory test information will be presented in summary core logs that will be generated upon completion of our exploration program.  Generate Seismic Design Parameters: Based on the geologic information obtained from our field exploration program in the vicinity of the improvements, HWA will determine the Site Class for seismic design and will generate seismic design parameters.  Develop Recommendations for Luminaires and Foundations: HWA will provide recommendations for bearing capacity and the foundation design of the cantilevered structures and the prefabricated building. Additionally, HWA will provide recommendations for luminaire foundations, assuming the use of WSDOT standard plan foundations.  Pavement Engineering Analysis and Recommendations: HWA will use the collected information regarding soil and groundwater conditions observed at the site to develop recommendations for the pavements at the proposed bus station platform such as subgrade preparation, aggregate base course, and minimum section thicknesses.  HWA QA/QC: HWA will have all design calculations and geotechnical recommendations reviewed by a senior principal prior to distribution to the design team or the City.  Draft Preliminary Geotechnical Engineering Report: HWA will prepare draft preliminary geotechnical report to support 30% design. This report will present the results of our field explorations, also it will include:  A description of the geotechnical site exploration program.  The logs of the site investigations, including any existing subsurface geotechnical data and pavement cores.  A description of the geologic and seismic setting for the corridor.  Results of all field tests conducted.
