The Contractor may authorize in writing a material or equipment supplier to deal directly with the Engineer with regard to a submittal. These dealings shall be limited to contract interpretations to clarify and expedite the work

28 3.0 CATEGORIES OF SUBMITTALS A. GENERAL: Submittals fall into two general categories; submittals for review and comment, and submittals which are primarily for information only. Submittals which are for information only are generally specified as PRODUCT DATA in Part 2 of applicable specification sections. At the beginning of work, the Contractor will furnish the Engineer with a list of submittals and approximate date of initial transmittal. The Contractor shall note which submittals will require comment. B. SUBMITTALS FOR REVIEW AND COMMENT: All submittals except where specified to be submitted as product data for information only shall be submitted by the Contractor to the Engineer for review and comment.

Submittal documents common to more than one piece of equipment shall be identified with all the appropriate equipment numbers. Submittals for various items shall be made with a single form when the items taken together constitute a manufacturer's package or are so functionally related that expediency indicates checking or review of the group or package as a whole. A unique number, sequentially assigned, shall be noted on the transmittal form accompanying each item submitted. Original submittal numbers shall have the following format: "XXX"; where "XXX" is the sequential number assigned by the Contractor. Resubmittals shall have the following format: "XXX-Y"; where "XXX" is the originally assigned submittal number and "Y" is a sequential letter assigned for resubmittals, i.e., A, B, or C being the 1st, 2nd, and 3rd resubmittals, respectively.

C. SUBMITTAL COMPLETENESS: Submittals which do not have all the information required to be submitted, including deviations, are not acceptable and will be returned without review. 5.0 REVIEW PROCEDURE A. GENERAL: Submittals are required for those features and characteristics of materials, equipment, and methods of operation which can be selected based on the Contractor's judgment of their conformance to the specified requirements. Other features and characteristics are specified in a manner which enables the Contractor to determine acceptable options without submittals. The review procedure is based on the Contractor's guarantee that all features and characteristics not requiring submittals conform as specified. Review shall not extend to means, methods, techniques, sequences or procedures of construction, or to verifying quantities, dimensions, weights or gages, or fabrication processes (except where specifically indicated or required by the project manual) or to safety precautions or programs incident thereto. Review of a separate item, as such, will not indicate approval of the assembly in which the item functions. When the contract documents require a submittal, the Contractor shall submit the specified information as follows: 1. Four (4) copies of all submitted information plus one reproducible original of all information shall be transmitted with submittals for review and comment. 2. Unless otherwise specified, three (3) copies of all submitted information shall be transmitted with submittals (Product Data) for information only. B. SUBMITTALS FOR REVIEW AND COMMENT: Unless otherwise specified, within twenty (20) calendar days after receipt of a submittal for review and comment, the Engineer shall review the submittal and return two (2) copies of the marked-up reproducible original noted in 1 above. The reproducible original will be retained by the Engineer. The returned submittal shall indicate one of the following actions: 1. If the review indicates that the material, equipment or work method complies with the project manual, submittal copies will be marked "NO EXCEPTIONS TAKEN." In this event, the Contractor may begin to

30 implement the work method or incorporate the material or equipment covered by the submittal. 2. If the review indicates limited corrections are required, copies will be marked "MAKE CORRECTIONS NOTED." The Contractor may begin implementing the work method or incorporating the material and equipment covered by the submittal in accordance with the noted corrections. Where submittal information will be incorporated in O&M data, the Contractor shall submit a corrected copy. 3. If the review reveals that the submittal is insufficient or contains incorrect data, copies will be marked "AMEND AND RESUBMIT." Except at his own risk, the Contractor shall not undertake work covered by this submittal until it has been revised, resubmitted and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED." 4. If the review indicates that the material, equipment, or work method does not comply with the Contract Documents, copies of the submittal will be marked "REJECTED - SEE REMARKS." Submittals with deviations which have not been identified clearly may be rejected. Except at his own risk, the Contractor shall not undertake the work covered by such submittals until a new submittal is made and returned marked either "NO EXCEPTIONS TAKEN" or "MAKE CORRECTIONS NOTED." C. SUBMITTALS (PRODUCT DATA) FOR INFORMATION ONLY: Such information is not subject to submittal review procedures and shall be provided as part of the work under this contract and its acceptability determined under normal inspection procedures. 6.0 EFFECT OF REVIEW OF CONTRACTOR'S SUBMITTALS Review of contract drawings, methods of work, or information regarding materials or equipment the Contractor proposes to provide, shall not relieve the Contractor of his responsibility for errors therein and shall not be regarded as an assumption of risks or liability by the Engineer, or by any officer or employee thereof, and the Contractor shall have no claim under the contract on account of the failure, or partial failure, of the method of work, material, or equipment so reviewed.

35 1.04 QUALITY ASSURANCE A. During the course of the Work, the Engineer may contract with a materials testing laboratory to perform periodic tests as are required to identify materials, to determine compaction characteristics, to determine moisture content, and to determine density of fill in place. These tests will be used to verify that backfill conforms to the requirements of these specifications. Such tests are not intended to provide the Contractor with information required for the proper execution of the work. Trial batch tests, field correlation tests, and test trenches, or shafts, shall establish minimum wet unit weight in order to prevent segregation and workability difficulties. B. Quality Assurance tests will be made by the Engineer. Additional tests as deemed necessary by the Engineer during the course of the work may be required. C. The Contractor shall provide safe access to the excavation for soil compaction testing technician or inspector. This shall include providing all safety equipment and temporary shoring to enable compaction testing at multiple levels in the excavation as directed by the Engineer. Should the Contractor have backfilled to an elevation above that required to be tested the Contractor shall excavate the backfill down to the necessary level for testing and provide shoring at the Contractor s cost. Subsequent backfilling shall also be at the Contractor s cost. D. The Contractor shall provide the Engineer access to the Work to perform Quality Assurance tests as the Engineers deems necessary. Contractor shall provide all safety equipment and provide surface or material preparations necessary to allow the Engineer to collect samples and perform tests in a safe and efficient manner QUALITY CONTROL A. Contractor shall contract with a qualified materials testing laboratory to provide all quality control testing under the contract. B. The Contractor shall be responsible for the Quality Control of the Work as specified in this Section. The Engineer will develop a Quality Assurance testing frequency to allow the Engineer to confirm the results of the Contractor s Quality Control testing program. C All materials and compaction testing for Quality Control will be done by a California certified testing laboratory at the Contractor s expense. D. If the first test and the re-test of the fill or backfill show non-compliance with the required density, the CONTRACTOR shall remove and recompact the fill until subsequent tests are successful. Subsequent testing to show compliance shall be by an independent testing laboratory possessing appropriate credentials at the Contractor s expense. The amount of fill removed for recompacting shall extend

36 1.06 DEFINITIONS COUNTY OF SACRAMENTO vertically and horizontally to the nearest successful density test. All remedial grading and recompaction shall be provided at no cost to the County. A. Pipe Bedding: Bedding material placed in an even compacted layer on the bottom of the smoothed dry trench bottom. B. Final Backfill: Backfill material from the top of the pipe bedding to the ground surface in unpaved areas. The final backfill shall consist of base material or suitable native backfill. C. Imported Material: Material obtained by the Contractor from source(s) offsite. D. Lift: Loose layer of material spread, but not compacted. E. Prepared Trench Bottom: Graded and smooth trench bottom prior to installation of pipe bedding material. F. Relative Compaction: The ratio, in percent, of the as-compacted field dry density to the laboratory maximum dry density as determined by ASTM D6938. Corrections for oversize material may be applied to either the as-compacted field dry density or the maximum dry density, as determined by the Engineer. G. Well-Graded: A mixture of particle sizes that has no specific concentration or lack thereof of one or more sizes producing a material type that, when compacted, produces a strong and relatively incompressible soil mass free from detrimental voids. Well-graded does not define any numerical value that must be placed on the coefficient of uniformity, coefficient of curvature, or other specific grain size distribution parameters. H. Optimum Moisture Content: The optimum moisture content of a specified material is determined by ASTM D1557, to obtain the maximum dry density of that material when compacted. Field moisture content shall be determined on the basis of the fraction passing the ¾-inch sieve WEATHER LIMITATIONS A. Material excavated during inclement weather shall not be used as fill or backfill until after material drains and dries sufficiently or has been blended with other suitable material to achieve proper moisture content that allows for proper compaction
