PART 1 GENERAL

1.1 DEFINITION

Hard material is defined as material requiring the use of special equipment for economical removal, and includes boulders or fragments too large to be removed in one piece by the dredge.

1.2 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. The following shall be submitted in accordance with Section 01300 SUBMITTAL PROCEDURES:

SD-02 Drawings

Soundings or Sweepings

Submit drawings of surveys during progress of work by soundings or sweepings.

SD-07 Certificates

Surveyor shall be experienced in hydrographic survey work. Contractor shall submit for approval the name, address, telephone number and firm literature or resume for two surveyors. The Contractor shall use the services of the approved surveyor only. The approved surveyor will be referred to as the registered surveyor in this specification.

1.4 MATERIAL TO BE REMOVED

The material to be removed is sand. Information regarding the material to be dredged from the project area is attached to this specification in Exhibit 1.

1.4.1 Hard Material

The removal of hard material is not included. Should the Government direct in writing that hard material be removed, the work shall be performed and an adjustment in the contract price or time for completion, or both, will be made in accordance with "FAR 52.236-2, Differing Site Conditions." If hard material is to be removed, blasting will not be permitted. Conduct operations in strict accordance with applicable regulations.

1.5 ARTIFICIAL OBSTRUCTIONS

Except as indicated on the plans and in Exhibit 2, the Government has no knowledge of cables, pipes, or other artificial obstructions or of any wrecks, wreckage, or other material that would necessitate the use of explosives or the employment of additional equipment for economical removal. If actual conditions differ from those stated or shown, or both, an adjustment in contract price or time for completion, or both, will be made in accordance with "FAR 52.236-2, Differing Site Conditions."

1.6 ADDITIONAL DREDGING

If necessary, the Contractor shall provide additional dredging above 3,920 cubic yards of dredge material needed to achieve project depth requirements indicated on the project drawings. Additional dredging quantity will be determined from before and after soundings.

1.6.1 OVERDEPTH DREDGING

Overdepth dredging is not required, but will be allowed to within two feet of the project depth requirement on the project drawings. Overdepth dredging quantity will be determined from before and after soundings. The Contractor will be paid for overdepth dredging up to a maximum quantity of 1,830 cubic yards. The Contractor will not be paid for overdepth dredging exceeding 1,830 cubic yards. The contractor shall take caution since overdepth dredging may cause damage to existing concrete and steel bulkheads, the existing 12-inch D.I. outfall pipe, and the existing pier.

1.7 SIDE SLOPES

Dredging on side slopes shall follow, as closely as practicable, the lines indicated or specified. The amount of material excavated from side slopes will be determined by either cross-sections or computer, or both.

1.8 PERMIT

The Contractor shall comply with conditions and requirements of the Corps of Engineers Permit and other State or Federal permits. The U S Coast Guard will secure the permit for dredging. The Contractor must use the dredged material disposal site indicated on the plans. Information regarding the material to be dredged from the project area is attached to this specification.
