4 PHYSICAL DATA

Information and data furnished or referred to in the Contract Documents are furnished for the CONTRACTOR'S information. However, it is expressly understood that the GOVERNMENT will not be responsible for any interpretation or conclusion drawn there from by the CONTRACTOR.

Likewise, the GOVERNMENT will not be responsible for any information provided to the CONTRACTOR by any information agency or other party.

The physical conditions of the Project Construction Site indicated in the Contract Documents are the results of site investigations conducted using topographic surveys, cultural resources surveys, and sediment sampling. While the GOVERNMENT’S topographic survey, cultural resources surveys and sediment samples are representative of surface or subsurface conditions at their specific locations and vertical reaches, variations in the characteristics of the surface or subsurface materials are possible and should be expected. Interpretations as shown in the Plans between sampling points are estimates of expected average conditions in these areas and are provided for the convenience and use by the CONTRACTOR but should not be taken as the actual conditions at each point beyond the sampling points. Should any questions or discrepancies arise, the CONTRACTOR shall report conditions to the GOVERNMENT immediately. A copy of the geotechnical report is included in Appendix A of these Technical Provisions of the Specifications.

4.1 Weather Conditions:

The Project Construction Site generally has a mild subtropical climate and may be affected by tropical storms and hurricanes primarily from June through November and by stormy and/or rainy weather, including severe thunderstorms, during any time of the year. The CONTRACTOR shall be responsible for obtaining information concerning rain and wind conditions that could influence safety and construction operations prior to making a bid. A list of publications containing climatological and meteorological observations and data for the Project Construction Site is provided below. Other publications or information sources are available in addition to the following:

Local Climatological Data: Monthly Summary published by the National Oceanic and Atmospheric Administration (NOAA), Asheville, NC. Subscription price and ordering information is available from the National Climatic Data Center, Federal Building, Asheville, NC 22801. This publication gives hourly wind speed and direction observations. The Annual Summary gives a summary of the observations for the period of record.

Summary of Synoptic Meteorological Observations: North American Coastal Marine Areas Atlantic and Gulf Coasts. Produced by the National Weather Service, U.S. Department of Commerce. Distributed by the National Technical Information Service, U.S. Department of Commerce.

5.3 Ratio of Mobilization (60%) and Demobilization (40%) Effort:

Sixty percent (60%) of the mobilization/demobilization Contract Lump Sum Price will be paid to CONTRACTOR upon complete mobilization to the Project Construction Site. The remaining forty percent (40%) will be paid to CONTRACTOR upon final acceptance of the Work and completion of Final Clean-up.

5.4 Justification of Costs:

In the event the GOVERNMENT considers that the cost for mobilization does not bear a reasonable relation to the cost of the entire Work in this Contract, the GOVERNMENT may require the CONTRACTOR to produce cost data to justify this portion of the bid. Failure to justify such price to the satisfaction of the GOVERNMENT will result in payment of estimated mobilization costs, as determined by the GOVERNMENT at the completion of mobilization, and payment of the remainder of this item in the final payment under this Contract.

10.4 Installation of FDOT #1 or FDOT #2 Coarse Aggregate:

The FDOT #1 or FDOT #2 coarse aggregate shall be placed by end dumping onto the geotextile fabric from the edge of the geotextile fabric, or over previously placed subbase aggregate. Direct traffic on the geotextile fabric, along with any sudden stops, starts, or turns on the FDOT #1 or FDOT #2 coarse aggregate by construction equipment, shall be avoided where possible. Using whatever means, the FDOT #1 or FDOT #2 coarse aggregate shall be machine spread from the back dumped pile. A minimum thickness of nine inches (9”) shall be maintained. A smooth drum roller shall be used to compact the FDOT #1 or FDOT #2 coarse aggregate while maintaining vertical tolerances. Any ruts occurring during construction shall be filled with additional FDOT #1 or FDOT #2 coarse aggregate and compacted to the target elevation. The use of vibratory compaction will not be allowed as it may cause damage to the geotextile.

10.5 Damage Repair:

Damaged geotextile fabric, as identified by the GOVERNMENT, shall be repaired immediately at the CONTRACTOR expense and at no additional cost to the GOVERNMENT. The damaged area, plus an additional three feet (3’) around the damaged area, shall be cleared of all coarse aggregate material. This area shall be covered with a geotextile fabric patch extending three feet (3’) beyond the perimeter of the damaged area. The removed coarse aggregate material shall be replaced and compacted to the target elevation.

10.6 Right to Vary the Low Water Crossings:

The GOVERNMENT reserves the right to vary the low water crossings from the lines shown on the Plans or observed at the Project Construction Site in order to avoid any unidentified public or private infrastructure, or to avoid other areas where the GOVERNMENT deems that the Work as shown on the Plans would be detrimental to the natural habitat at no additional cost to the GOVERNMENT.

TP-16

10.7 Equipment:

Equipment employed for the low water crossing Work shall be in satisfactory operating condition, capable of safely and efficiently performing the Work as indicated.

Equipment and machinery shall be kept in good condition at all times.

A listing of all equipment and machinery utilized to accomplish the Work shall be submitted prior to mobilization as part of 10.8.1-Pre-construction Submittals of these Technical Provisions of the Specifications. The listing shall include year and manufacturer, operational capacities, safety features, operating and licensing requirements for operators, and a description of where and how the item of equipment will be employed in the Work. Any leaks or deficiencies shall be promptly and properly repaired. The CONTRACTOR is responsible for cleaning any fuel, oil, grease or other spills and reporting these incidents to the GOVERNMENT.

10.8 Submittals:

10.8.1 Prior to commencing any Work at the Project Construction Site the

CONTRACTOR shall submit the following:

a. Pre-construction Submittals:

The CONTRACTOR shall submit a low water crossing plan to the GOVERNMENT which shall include the following:

1. Clearly identifies roads to remain in place;

3. Lists equipment and machinery to be used during low water crossing Work.

10.8.2 Certified Rock Quantity:

The CONTRACTOR shall provide records of the net weight of coarse aggregate and/or rock transported to the Project Construction Site. The CONTRACTOR shall provide the GOVERNMENT with a weekly cumulative total of all rock by size delivered to the Project Construction Site and a total of all coarse aggregate placed by weight. Signed weight tickets and any other records shall be provided to the GOVERNMENT weekly.

10.8.3 Within ten (10) Days after completion of Work, the CONTRACTOR shall submit the following:

a. Post-construction Submittals:

1. As-Built survey data (see section 7.6-Survey Submittals of these

Technical Provisions of the Specifications); and

2. Documentation of the spatial extents of the low water crossing areas in the form of a GIS shapefile, or Google Earth .kml or .kmz file.

The GOVERNMENT may elect to have those performed individually but will not require the CONTRACTOR to wait for the GOVERNMENT to be on-site for the CONTRACTOR to progress with the next phase of construction.

*A hold point inspection for this LWC shall occur only after the award of the associated Bid Alternative.

12 EROSION CONTROL MEASURES

12.1 Scope:

The CONTRACTOR shall obtain and maintain compliance with a construction stormwater NPDES Permit and implement and maintain effective erosion and sediment controls in accordance with the SWPPP. Means and methods for controlling erosion shall be determined by the CONTRACTOR.
