1.4 FIELD SURVEYS

No separate payment will be made for field surveys. All costs for surveys shall be considered incidental to the closest associated feature of work.

The volume of material for payment of excavation shall be determined by the average end area method and the pre- and post excavation surveys. The Contractor will not be paid for material remaining outside of the specified tolerances.

Pre- and post-placement survey cross sections shall be performed for the excavation, embankment fill, and riprap; and the results submitted to the Contracting Officer. Surveys shall be performed by a land surveyor with current Commonwealth registration. The Contractor shall notify the Contracting Officer not less than three working days in advance of each survey. Surveys shall be conducted in the presence of the Contracting Officer or his designated representative unless this requirement is waived.

In the event of unavailability of the Contracting Officer, the Contractor shall perform the survey and certify that it complies with the specifications.

The Contractor will be responsible for establishing, protecting and maintaining a baseline. A schematic of the baseline shall be provided to the Contracting Officer along with horizontal coordinates at the endpoints and at all changes in alignment. These horizontal coordinates shall be in the Kentucky State Plane, NAD 83 coordinate system and shall be to the nearest foot with accuracy of +/- 0.5 foot.

Drawings shall utilize A/E/C CADD standards, Latest Release. All electronic drawings shall be submitted to the Government in MicroStation ".dgn" format and ".pdf" portable document format. Drawings should be developed using Arial Font for text, and A/E/C CADD standard ".dgnlibs" for level assignment, line weights, line styles, and line color. A copy of the "dgnlibs" will be furnished. Civil site plan drawings shall utilize a standard engineering drawing scale. Additionally, provide all CAD files to include but not limited to .dtm, .alg, .eav, .xyz, .xls, .xsc, and .ASCII or .XML file types used to generate electronic drawings such as contours, .dtms, plan views, profiles, and cross sections so that USACE may be able to regenerate those profiles, cross sections, contours, alignments, etc as needed during the design process.

Cross-sections shall be surveyed perpendicular to the channel alignment and shall be no more than 25 feet apart as measured along the baseline. The readings shall be at 5-foot intervals and at breaks in grade unless otherwise specified. Additional sections at closer spacing for significant changes in topography may be required as determined appropriate by the Contracting Officer. The station at which the cross-section intersects the baseline shall be used to identify it. Surveyed elevations shall reference the same datum used on the drawings and shall be to the nearest tenth of a foot with an accuracy of +/- 0.1 foot. Additional elevations shall be taken if the Contracting Officer deems such to be necessary or advisable.

The top elevation of placed riprap shall be determined by the use of a leveling instrument and a rod having a base 12 inches in diameter.

SECTION 01 22 00 Page 13

1.4.1 Surveys of Riprap Areas

In order to define the original ground surface, the Contractor shall take cross sections of the area to receive riprap after preparation of the foundation and prior to placing material. Another survey at the same sections shall be performed after riprap has been placed. The Contractor shall perform partial surveys as the work progresses to verify lines, grades and thickness established for completed work. Surveys made are required to determine that the material has been acceptably placed. At least one in-progress survey shall be made by the Contractor as determined appropriate by the Contracting Officer. Following placement, the cross-sections shall be approved by the Contracting Officer before proceeding with the next section of work. Approval of cross-sections based upon in-progress surveys shall not constitute final acceptance of the work.

A final as-built survey shall be performed after all riprap has been placed. Survey results shall include electronic scaled drawings of data submitted as cross section plots. The Contracting Officer may also require the Contractor to submit survey field notes. For the purpose of coordinating with the Government, the Contractor shall schedule surveys during the normal business hours of Monday through Friday 7:00 a.m. to 3:30 p.m. Central Time with the exception of Federal Holidays.

1.4.2 Surveys of Excavated Areas

For surveys of excavation, the same procedures specified above shall be followed. The initial survey shall be taken after clearing and grubbing has been completed and prior to excavation. The final survey shall be taken after excavation and grading is complete. The volume of excavated material for payment shall be determined by the average end area method based on these two surveys. Survey results shall be submitted to the Government.

1.5 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for information only. When used, a designation following the "G" designation identifies the office that will review the submittal for the Government. Submit the following in accordance with Section 01 33 00 SUBMITTAL PROCEDURES:

3.1 CONTRACT COST BREAKDOWN

The Contractor must furnish within 30 days after the date of Notice to Proceed, and prior to the submission of its first partial payment estimate, a breakdown of its single job pay item or items which will be reviewed by the Contracting Officer as to propriety of distribution of the total cost to the various accounts. Any unbalanced items as between early and late

SECTION 01 22 00 Page 14 payment items or other discrepancies will be revised by the Contracting Officer to agree with a reasonable cost of the work included in the various items. This contract cost breakdown will then be utilized as the basis for progress payments to the Contractor.

1.3 SUBMITTALS

Government approval is required for submittals with a "G" designation;

submittals not having a "G" designation are for Contractor Quality Control approval. Submit the following in accordance with Section 01 33 00

SUBMITTAL PROCEDURES:

SD-03 Product Data

Wood cellulose fiber mulch

Fertilizer

Include physical characteristics, and recommendations.

Hay or Straw Mulch

The COR shall be notified of sources from which mulch materials are available and the quantities thereof, and representative

SECTION 32 92 19 Page 3 samples of the materials proposed for the use shall be submitted for approval. Mulch and straw delivered to the job will be reviewed for quality, weed, and weed seed content prior to application.

SD-06 Test Reports

Topsoil composition tests (reports and recommendations).

Fertilizer and Lime; G

Triplicate copies of invoices shall be furnished. Invoices shall show quantity, grade of fertilizer, percentage of calcium oxide or magnesium oxide, as applicable, and the percentages of lime that pass the 20 and 100 mesh sieves. Samples of each lot of fertilizer and lime shall be furnished for testing as directed. Samples will be tested at Government expense, in accordance with Official Methods of Analysis (AOAC Methods) of the Association of Official Analytical Chemists, at the discretion of the Contracting Officer.

Upon completion of the project, a final check of total quantities of fertilizer and lime used will be made against total area treated, and if minimum rates of application have not been met, additional quantities of these materials to make up minimum application specified shall be distributed as directed.

SD-07 Certificates

Apply seed within twenty four hours after seedbed preparation. Sow seed by

SECTION 32 92 19 Page 9 approved sowing equipment. Sow one-half the seed in one direction, and sow remainder at right angles to the first sowing.
