64 <br />1. Excavation observation and placement of fill <br />a. Perform geotechnical exploration and review reports, providing boring logs, conclusions, <br />opinions, and recommendations. <br />b. Observe exposed soils in the bottom of excavations, documenting the elevation and <br />keeping detailed notes. <br />c. Perform shallow hand auger borings and hand cone penetrometer probes, as necessary. <br />d. Evaluate the suitability of soils to support structural loads and pavements, and document <br />adequate oversizing for load support. <br />e. Provide compaction testing to evaluate fill density using the sand cone, or nuclear density <br />method. <br />f. Conduct standard or modified proctor tests on differing fill to be placed, and obtain <br />samples for sieve test or other classification analysis. <br />2. Concrete testing <br />a. Documentation of correct mix delivery. <br />b. Slump tests. <br />c. Air content tests. <br />d. Measuring temperature of the concrete at placement. <br />e. Compare results to project specifications and report discrepancies immediately. <br />f. Provide daily field reports, or as directed. <br />3. Subgrade observation and test rolls <br />a. Observe stability during test- rolling. <br />b. Evaluate deflection under wieel loads, and mark areas of excessive deflection for <br />corrective actions. <br />c. Provide recommendations for correction of unstable subgrade soils. <br />d. Present results of observations in a written report, if requested. <br />4. Pavement testing <br />a. Observe rolling procedures and assist in establishing a pattern to achieve design density <br />during placement. <br />b. Obtain samples of bituminous for laboratory testing, including: <br />• Marshall density <br />• Rice specific gravity <br />• Asphalt extraction <br />• Aggregate gradation <br />V Proposal Criteria <br />Proposals should be presented in the following order, showing the following details as a <br />minimum: <br />1. Firm name, address, phone, fax, primary contact person, and date of proposal. <br />2. Profile of the firm, including history, experience, and client references. <br />2 <br />
