1. Division 00 - Bidding Requirements, Contract Forms, and Conditions of the Contract.

2. Division 01 - General Requirements.

3. Section 01 45 26 – Interface Friction Tests

1.2 CONDITIONS SPECIFIC TO THIS PROJECT

A. CQC/CQA Duties: In general, the CQC Consultant will perform all testing related to earthwork and soil liner work and provide documentation to the CQA Consultant. The CQA Consultant will conduct the destructive geosynthetic testing and official construction documentation for submission to the SCDES. CQC and CQA documentation will be used by the CQA Consultant to prepare and submit final certification to SCDHEC. The majority of the CQC responsibilities and all of the testing requirements are defined by these specifications. However, CQC/CQA communication is addressed in the CQA Plan. The majority of the CQA responsibilities are defined by the CQA Plan.

B. The CONTRACTOR (Geosynthetic Installer/Supplier) is responsible for construction of any additional access/haul roads; however their locations are subject to approval by the OWNER.

The Contractor shall repair/reconstruct all existing roads and features to preconstruction condition or better, regardless of use of these by others. In the absence of preconstruction condition documentation by the contractor, they shall be repaired to the satisfaction of the OWNER. All roads shall be passible by a pickup truck traveling 15 mph at the completion of work.

C. Site Access:

1. The primary access to the site available to the CONTRACTOR is entering through the existing contractor’s entrance on U.S. Highway 25. The CONTRACTOR is responsible for securing this entrance at all times.

2. Access via the paved landfill entrance shall be only for attending meetings and as allowed by the OWNER.

1.3 DATA AND MEASUREMENTS

A. The data given in the Specifications and shown on the Drawings is believed to be accurate but the accuracy is not guaranteed. The Contractor must take all levels, locations, measurements, and verify all dimensions of the job site prior to construction and must adapt his work into the exact construction. Larger scale Drawings take precedence over smaller scale Drawings, and approved shop drawings take precedence over all others.

PART 2 - PRODUCTS

2.1 INTERFACE FRICTION TESTS

A. If any interface doesn’t meet the requirements, or if the CONTRACTOR changes geosynthetic materials, then the additional cost to qualify those materials shall be borne by the CONTRACTOR. Refer to 01 45 26 – INTERFACE FRICTION TESTS.

1.5 ENGINEER'S REVIEW ACTION

A. Shop Drawings and Samples:

1. Items within transmittals will be reviewed for overall design intent and will receive one (1) of the following actions:

a. A - FURNISH AS SUBMITTED.

b. B - FURNISH AS NOTED (BY ENGINEER).

SUBMITTALS

01 33 00 - 5

c. C - REVISE AND RESUBMIT.

d. D - REJECTED.

e. E - ENGINEER'S REVIEW NOT REQUIRED.

2. Submittals received will be initially reviewed to ascertain inclusion of Contractor's approval stamp.

a. Submittals not stamped by the Contractor or stamped with a stamp containing language other than that specified herein will not be reviewed for technical content and will be returned rejected.

3. In relying on the representation on the Contractor’s review and approval stamp, Owner and Engineer reserve the right to review and process poorly organized and poorly described submittals as follows:

a. Submittals transmitted with a description identifying a single item and found to contain multiple independent items:

1) Review and approval will be limited to the single item described on the transmittal letter.

2) Other items identified in the submittal will:

a) Not be logged as received by the Engineer.

b) Be removed from the submittal package and returned without review and comment to the Contractor for coordination, description and stamping.

c) Be submitted by the Contractor as a new series number, not as a re-submittal number.

b. Engineer, at Engineer’s discretion, may revise the transmittal letter item list and descriptions, and conduct review.

1) Unless Contractor notifies Engineer in writing that the Engineer’s revision of the transmittal letter item list and descriptions was in error, Contractor’s review and approval stamp will be deemed to have applied to the entire contents of the submittal package.

4. Submittals returned with Action "A" or "B" are considered ready for fabrication and installation.

a. If for any reason a submittal that has an "A" or "B" Action is resubmitted, it must be accompanied by a letter defining the changes that have been made and the reason for the resubmittal.

b. Destroy or conspicuously mark "SUPERSEDED" all documents having previously received "A" or "B" Action that are superseded by a resubmittal.

5. Submittals with Action "A" or "B" combined with Action "C" (Revise and Resubmit) or "D" (Rejected) will be individually analyzed giving consideration as follows:

a. The portion of the submittal given "C" or "D" will not be distributed (unless previously agreed to otherwise at the Preconstruction Conference).

1) One (1) copy or the one (1) transparency of the "C" or "D" Drawings will be marked up and returned to the Contractor.

a) Correct and resubmit items so marked.

b. Items marked "A" or "B" will be fully distributed.

c. If a portion of the items or system proposed are acceptable, however, the major part of the individual Drawings or documents are incomplete or require revision, the entire submittal may be given "C" or "D" Action.

1) This is at the sole discretion of the Engineer.

SUBMITTALS

01 33 00 - 6

2) In this case, some Drawings may contain relatively few or no comments or the statement, "Resubmit to maintain a complete package."

3) Distribution to the Owner and field will not be made (unless previously agreed to otherwise).

6. Failure to include any specific information specified under the submittal paragraphs of the Specifications will result in the submittal being returned to the Contractor with "C" or "D" Action.

7. Calculations required in individual Specification Sections will be received for information purposes only, as evidence calculations have been stamped by the professional as defined in the specifications and for limited purpose of checking conformance with given performance and design criteria. The Engineer is not responsible for checking the accuracy of the calculations and the calculations will be returned stamped "E. Engineer's Review Not Required" to acknowledge receipt.

8. Contractor shall furnish required submittals with sufficient information and accuracy to obtain required approval of an item with no more than three submittals. Engineer will record Engineer’s time for reviewing a fourth or subsequent submittal of a Shop Drawings, sample, or other item requiring approval, and Contractor shall be responsible for Engineer’s charges to Owner for such time. Owner may impose a set-off against payments due to Contractor to secure reimbursement for such charges.

9. Transmittals of submittals which the Engineer considers as "Not Required" submittal information, which is supplemental to but not essential to prior submitted information, or items of information in a transmittal which have been reviewed and received "A" or "B" action in a prior submittal, will be returned with action "E.

Engineer's Review Not Required."

10. Samples may be retained for comparison purposes.

a. Remove samples when directed.

b. Include in bid all costs of furnishing and removing samples.

11. Approved samples submitted or constructed, constitute criteria for judging completed work.
