5 . IP 24-13 Fox Ridge Estates 1" & 2nd Street Reconstruction • Subdivision is generally located west of TH 47 between 170th Avenue and 174th Avenue, west to Wolfram Street. a. Streets are approximately 2.11 miles in total length i. 30-feet wide, rural section with bituminous curb ii. Speed limit is 30 mph b. Scope of work includes: i. 26 soil borings to a depth of 10-feet per the attached exhibit 1. Twenty -Six (26) Pavement Cores ii. A standard geotechnical report including construction feasibility for public utilities and pavement section iii. Logs of soil borings with descriptions of nomenclature used for defining the site soils iv. Estimated subgrade support strength parameters for design of the bituminous roadway and recommendations for soil corrections v. Recommendations for earthwork associated with installation of storm sewer vi. Recommendations for management of groundwater for design of structures and pavements SOIL BORING REQUIREMENTS: Soil borings to a depth called out above will be taken at stationing shown on the attached "Boring Hole Location" exhibits. Soil borings will alternate between drive lanes as practical. Cores of the existing bituminous pavement will be required. Cores will be taken to verify thickness and structural integrity of the existing pavement and base. Pictures of the cores will be included in the final report. Any additional depth beyond depth called out will be paid per lineal foot. The Contractor must perform sufficient survey work to locate holes approximately 5 feet horizontally and approximately 0.5 feet vertically. The Contractor is responsible for locating all utilities prior to starting boring operations. SOIL BORING LOG REQUIREMENTS: A field boring log will be prepared by the Contractor for each boring with a copy included in the final report. The field boring logs will include; • The project identification number • Location of the boring referenced by centerline stationing • Boring log number • Method of drilling and sampling, diameter of bore hole • Date, name of driller and crew • Ground surface elevation and ground water elevation measured to the nearest 0.5 feet • Definition of all symbols that are not otherwise self-explanatory • Classification, thickness, color, moisture condition (dry, moist, wet, saturated), composition and degree of compactness • Field number of any samples taken, type of sample and depth taken • Depth at which obstacles were encountered in advancing the boring • Any other unusual conditions encountered during drilling and sampling 11
