November 7, 1994 s9l 11 2-05 Mr. Richard Cook 4, City of Carlsbad 2075 Las Palmar Avenue Carlsbad, CA 92008 (4 OD Project: Avenida Encinas Widening Segments'A and B Subject: Calculation of Earthwork Pay Quantities Dear Mr. Cook: At the direction of the City of Carlsbad through Joe Federico, City of Carlsbad construction inspector, Fraser Engineering performed topographic surveys and earthwork volume calculations for the above referenced project. We performed topographic field surveys both prior to the project construction (original ground condition), and prior to the import of offsite borrow material (ground before import borrow condition). Computer generated digital terrain surfaces were created for the project site to model the original ground condition, the ground before import borrow condition, and the design subgrade condition. Earthwork volume calculations were performed using these terrain models with the results for segments A and B presented as follows: Unclassified Ex. Eli Import Borrow Segment A: 140 cy cut 4,335 cy fill (4,195 cy) Segment B: 2,470 cy cut 2,505 cy fill ( 35 cy) Project Total: 2,610 cy cut 6,840 cy fill (4,230 cy) Project Pay Quantities: Unclassified Excavation 2,610 cy Import Borrow 4,230 cy The above mentioned cut and fill volumes include an allowance of 385 cy for existing pavement removal from Segment "B" which is classified as clear and grub material. Additionally, as shown above, the Project Pay Quantities include an adjustment of 2,610 cy for cut material (unclassified excavation) which was present at the time of the topographic survey for imported borrow. If you have any questions regarding the field survey and/or our earthwork volume calculations please do not hesitate to contact me or David Tayari of our office. Sincerely, FRASER ENGINEERING, INC.
