Street are approximately 0.54 miles in total length 1. 31-feet wide, urban section with bituminous curb 2. No municipal utilities exist or are proposed ii. Scope of work includes: 1. Eight (8) soil borings to a depth of 10-feet per the attached exhibit 2. Seven (7) pavement cores iii. A standard geotechnical report including construction feasibility for public utilities and pavement section 1. Streets require a 7-ton pavement design a. Typically, City would do an FDR or full reconstruction 2. Logs of soil borings with descriptions of nomenclature used for defining the site soils 3. Estimated subgrade support strength parameters for design of the bituminous roadway and recommendations for soil corrections; Design R-Value estimate 4. Recommendations for earthwork associated with installation of storm sewer pipes and structures a. Considerations for infiltration rate within low area at 16021 Xenolith Street 5. Recommendations for management of groundwater for design of structures and pavements 6. 2024 Gravel Roads a. Six (6) gravel roads located across the City i. Streets are approximately 1.90 miles in total length ii. Typically, 24-foot wide rural section b. Scope of work includes: i. Twenty-four (24) soil borings to a depth of 10-feet per the attached exhibit c. A standard geotechnical report including construction feasibility for shallow storm sewer construction and pavement section i. Streets require a 7-ton pavement design 1. Typical City Street section is 3.5-inch bituminous over 4 to 6-inch class 5 ii. Logs of soil borings with descriptions of nomenclature used for defining the site soils iii. Estimated subgrade support strength parameters for design of the bituminous roadway and recommendations for any soil corrections; Design R-Value estimate iv. Recommendations for earthwork associated with installation of storm sewer pipes and structures v. 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. 4
