The Contractor shall prosecute the dredging work in the Charleston Entrance Channel at a minimum production rate of 700,000 cubic yards for each quarter (3-months) over the entire project period of performance from 45 days after issuance of the NTP; provided that excavation and disposal efforts shall be pursued in a continuous manner from commencement until fully complete with no continuous period without bonafide production work greater than 30 calendar days except for excusable delays as permitted by the Default Clause or authorized by the Contracting Officer. ”

Temporary suspension of trawling for repairs over 24 hours will not be considered continuous trawling for the purposes of payment, but will not cause dredging to cease, subject to approval by the Contracting Officer.”

6. SECTION 35 20 23 DREDGING, Paragraph “Continuity of Work”

DELETE the entire paragraph and REPLACE with “Final payment for and formal acceptance of Acceptance Sections will not be rendered until the Acceptance Section is excavated to the full depth and extents required by the contract.

The desired quality of material will be primarily new work limestone. Once an area is agreed upon by both parties, material that is mechanically dredged from this area will be acceptable for construction of mitigation reefs, unless that material drastically differs from the desired primary material stated above (i.e. mud, silt, sand, clay).”
