Common use of FIELD AND LABORATORY REPORTS Clause in Contracts

FIELD AND LABORATORY REPORTS. The CONSULTANT shall prepare field and laboratory reports as follows: a. All segments of the reports covering the investigations and analyses shall be made on white paper, 8-1/2 x 11 inches, suitable for photocopying and bound in booklet form. If larger drawings are necessary, they shall be folded and bound into the booklet. Written reports and analyses shall be on the CONSULTANT’s letterhead. Each drawing shall carry a title block which contains the PROJECT name and location, the Registered Geotechnical Engineer’s name and address, the date of the subsurface investigation, the date of the drawings, the initials of the person in charge of the crew making the investigation, the initials of the drafter, and the initials of the California Registered Professional Engineer who is the responsible checker. b. All data required to be recorded according to the American Society for Testing Materials (“ASTM”) Standards or other standard test methods employed shall be obtained, recorded in the field and referenced to boring numbers; soil shall be classified in the field logs in accordance with current applicable ASTM Standards and other standards, including but not limited to ASTM Standard D2488, but the classification for final logs shall be based on the field information, plus results of tests plus further inspection of samples in the laboratory by CONSULTANT. c. Include with the report a chart illustrating the soil classification criteria and the terminology and symbols used on the boring logs. d. Identify the ASTM Standards or other recognized standard sampling and test methods utilized. e. Provide a plot plan giving dimensioned locations of test borings. f. Provide vertical sections for each boring plotted and graphically presented showing number of borings, sampling method used, date of start and finish, surface elevations, description of soil and thickness of each layer, depth to loss or gain of drilling fluid, hydraulic pressure required or number of blows per foot (N value) and, where applicable, depth to wet cave-in, depth to artisan head, groundwater elevation and time when water reading was made (repeat observation after 24 hours) and presence of gases. Note the location of strata containing organic materials, wet materials or other inconsistencies that might affect Engineering conclusions. g. Describe the existing surface conditions and summarize the subsurface conditions. h. Provide a profile and/or topographic map of rock or other bearing stratum. i. Analyze the probable variations in elevation and movements of subsurface water due to seasonal influences. j. Report all laboratory determinations of soil properties.
