Major tasks associated with this work include the items described in Paragraph I-2 of these Technical Specifications and Special Provisions of the Specifications.

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 OWNER will not be responsible for any interpretation or conclusion drawn there from by the CONTRACTOR.

Likewise, the OWNER 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 on the Plans and in the Specifications are the results of site investigations conducted using topographic surveys, cultural resources surveys, and sediment sampling. While the OWNER’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 of 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 OWNER immediately.

Copies of the boring logs are included in Appendix A: Geotechnical Report of these Technical Specifications and Special 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:

4.1.1 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.

5. ENVIRONMENTAL PROTECTION PROVISIONS

5.1 Scope:

The Environmental Protection Provisions address CONTRACTOR responsibilities for the prevention of pollution and other environmental damage as the result of construction operations under the Contract Documents. For the purpose of this Specification, pollution and other environmental damages are defined as the presence of chemical, physical, or biological elements or agents that adversely affect human health or welfare;

unfavorably alter ecological balances of importance to human life; affect other species of importance to man; degrade the utility of the environment for aesthetic, cultural, and/or historical purposes; or unnecessarily damage/destroy environmental resources. The control of pollution and damage requires consideration of air, water, land, and the marine environment and includes management of construction activities, visual aesthetics, noise, solid waste, radiant energy, and radioactive materials, as well as other pollutants. The CONTRACTOR shall fulfill these provisions at the CONTRACTOR'S expense.

5.2 Quality Control:

The CONTRACTOR shall establish and maintain quality control for environmental protection for all items set forth herein. The CONTRACTOR shall record on any problems in complying with laws, regulations, and ordinances, as well as project Permits and corrective action taken.

Nevertheless, it remains the sole responsibility of the CONTRACTOR to comply with all applicable Federal, State, and Local laws and regulations, Permits, and all elements of the Environmental Protection Plan. If there is known non-compliance, the OWNER will determine what action will be taken and such response will be transmitted to the CONTRACTOR by the OWNER, which may include stopping construction of the work at the cost of the CONTRACTOR until the CONTRACTOR complies with the Environmental Protection Plan. It shall also be the CONTRACTOR'S responsibility that all subcontractors comply with all applicable laws, regulations, Permit requirements, and all elements of the Environmental Protection Plan.

5.6 Protection of Environmental Resources:

The environmental resources within the Project Construction Site and those affected outside the limits of Project Construction Site under this Contract shall be protected during the entire period of this Contract. The CONTRACTOR shall, at all times, maintain adequate stakes or other markers required to delineate areas of the work to ensure the protection of resources. The disturbance of lands and waters that are outside the Project Construction Site limits is prohibited, except as found necessary and approved by the OWNER and any associated Permits. The CONTRACTOR shall conduct his work in such manner as to prevent the entry of fuels, oils, bituminous materials, chemicals, sewage, or other harmful materials into streams, lakes, marshlands, bays, or the Intracoastal Waterway. All waterways shall be cleared as soon as practicable of false work, stakes, piling, debris, or other obstructions placed during construction operations and not a part of the finished work. Details regarding environmental protection shall be as stated in the following subparagraphs.

5.6.1 Protection of Land Resources:

Prior to the beginning of any work, and at the request of the CONTRACTOR, the OWNER shall identify land resources (if any) to be preserved within the CONTRACTOR'S Project Construction Site. Unless indicated in the Plans or directed by the OWNER, the CONTRACTOR shall not remove, cut, deface, injure, or destroy land resources including marsh or berm vegetation, trees, shrubs, vines, grasses, topsoil, and landforms without direct written permission from the OWNER. No ropes, cables, or guy lines shall be fastened to or attached to any trees for anchorage unless specifically authorized by the OWNER. Where such special emergency use is allowed, the CONTRACTOR shall provide effective protection for land and vegetation resources at all times as defined in the following paragraphs. The CONTRACTOR shall be responsible for the replacement of any damaged or destroyed vegetation outside the Project Construction Site and outside the approved work areas as indicated on the Plans and the restoration of any water bottoms and land forms to the satisfaction of the OWNER. Failure to replace damaged or destroyed vegetation or failure to restore damaged water bottoms and land forms outside the Project Construction Site and outside the approved work areas as indicated on the Plans by the CONTRACTOR may result in replacement by the OWNER; the cost of replacement may be deducted from any money due, or to become due, to the CONTRACTOR or may be recovered under their bond.
