SECTION 01 30 10

CONTRACTOR SUBMITTALS

1.01 PRE-CONSTRUCTION MEETING SUBMITTALS

A. At the pre-construction meeting, the Contractor shall submit the following items to the Engineer for review:

1. A preliminary schedule of Shop Drawings submittals and target dates for the project prior to start of construction.

2. Schedule of values that will be used for payment applications.

3. A list of any and all permits and licenses the Contractor shall obtain indicating the agency required to grant the permit and the expected date of submittal for the permit and required date for receipt of the permit.

4. Insurance certificates.

5. Health and Safety Plan.

1.02 SHOP DRAWINGS

A. Wherever called for in the Contract Documents, or where required by the Engineer, the Contractor shall furnish to the Engineer for review, one (1) copy of each submittal. The term “submittal” as used herein shall be understood to include detail design calculations, shop drawings, fabrication and installation drawings, lists, graphs, operating instructions, catalog sheets, data sheets, samples, and similar items. Unless otherwise required, said submittals shall be submitted to the Engineer, 15 days minimum prior to planned work activity to allow review of same by the Engineer, and to accommodate the rate of construction progress required under the Contract. Should any submittal be a part of any schedule milestone and is considered to be unacceptable by the County, the appropriate milestone shall be considered as not having been met until a complete and properly detailed submittal is received.

B. Attach to the front of each submittal a title sheet stating the pertinent product information submitted and reference the appropriate Specification Section and Paragraph. Apply stamp, signed or initialed, certifying that all quantities, dimensions, field construction criteria, materials, catalog numbers, and specified performance criteria has been reviewed in accordance with the requirements of the Work and the Contract Documents.

If this information is not provided with each submittal, the submittal shall be

2025 Landfill Gas Collection and Control System Expansion 01 30 10-2 returned to the Contractor without action taken by the Engineer, and any delays caused thereby shall be the total responsibility of the Contractor.

C. All shop drawings or other submittals shall be accompanied by the County’s standard submittal transmittal form, or other form mutually agreed upon at the pre-construction meeting. Any submittal not accompanied by the approved form or if all applicable items on the form are not completed, the submittal will be returned to the Contractor without action taken by the Engineer.

D. Normally, a separate transmittal form shall be used for each specific unrelated item or class of material or equipment for which a submittal is required.

Transmittal of a submittal of various items using a single transmittal form will be permitted only when the items taken together constitute a manufacturer’s “package” or are so functionally related that this helps speed the review of the group or package as a whole. A multiple-page submittal shall be collated into sets, and each set shall be stapled or bound, as appropriate, prior to transmittal to the Engineer.

E. Except as may otherwise be provided herein, the Engineer will return prints of each submittal to the Contractor, with comments noted thereon, within 15 calendar days following their receipt by the Engineer. It is considered reasonable that the Contractor shall make a complete and acceptable submittal to the Engineer by the second submission of a submittal item. The County reserves the right to withhold monies due the Contractor to cover additional costs of the Engineer’s review beyond the second submittal.

F. If a submittal is returned to the Contractor marked “NO EXCEPTIONS TAKEN,” formal revision and resubmission of said submittal will not be required.

G. If a submittal is returned to the Contractor marked “MAKE CORRECTIONS NOTED,” formal revision and resubmission of said submittal will not be required. However, Contractor shall address the comments/corrections in the final Work. Revisions indicated on submittals shall be considered as changes necessary to meet the requirements of the Contract Documents and shall not be taken as the basis of claims for extra work.

H. If a submittal is returned to the Contractor marked “AMEND - RESUBMIT,” the Contractor shall revise said submittal per Engineer’s comments and shall resubmit the required number of copies of said revised submittal to the Engineer.

I. If a submittal is returned to the Contractor marked “REJECTED - RESUBMIT,” the Contractor shall revise said submittal and shall resubmit the required number of copies of said revised submittal to the Engineer.

J. Fabrication of an item shall not commence before the Engineer has reviewed the pertinent submittals and returned copies to the Contractor marked either “NO EXCEPTIONS TAKEN” or “MAKE CORRECTIONS NOTED.” Revisions

2025 Landfill Gas Collection and Control System Expansion 01 30 10-3 indicated on submittals shall be considered as changes necessary to meet the requirements of the Contract Documents and shall not be taken as the basis of claims for extra work.

K. All Contractor submittals shall be carefully reviewed by an authorized representative of the Contractor prior to submission to the Engineer. Each submittal shall be dated, signed, and certified by the Contractor as being correct.

Contractor shall use the County-approved shop drawing stamp agreed upon at the pre-construction meeting. No consideration for review by the Engineer of any Contractor submittals will be made for any items which have not been so certified by the Contractor. All non-certified submittals will be returned to the Contractor without action taken by the Engineer, and any delays caused thereby shall be the total responsibility of the Contractor.

L. The Engineer’s review of the Contractor submittals shall not relieve the Contractor of the entire responsibility for the correctness of details and dimensions. The Contractor shall assume all responsibility and risk for any misfits due to any errors in the Contractor submittals. Any fabrication or other work performed in advance of the receipt of approved submittals shall be entirely at the Contractor’s risk and expense. The Contractor shall be responsible for the dimensions and the design of adequate connections and details.

M. Product Data

1. Submit only pages which are pertinent; mark each copy of standard printed data to identify pertinent products, reference it to Specification Section and Paragraph number. Show reference standards, performance characteristics, and capacities; dimensions; and required clearances.

2. Modify manufacturer’s standard schematic drawings and diagrams to supplement standard information and to provide information specifically applicable to the Work. Delete information not applicable.

3. Failure to follow the guidelines in paragraphs 1 and 2 above shall be grounds for rejection of Contractor submittals.

N. Contractor shall notify Engineer in writing, at time of submittal, of proposed deviations from requirements of Contract Documents.
