1.2 SEVERE WEATHER

The table below provides monthly minimum anticipated adverse weather for the project region, scope of work, and anticipated equipment. It is based on National Oceanic and Atmospheric Administration (NOAA) or similar historical data for the region. The anticipated adverse weather is normal for the region and must be anticipated in the project schedule.

At a minimum, the contractor's schedule must incorporate these anticipated adverse weather delays in all on-site, weather-dependent activities. For off-site work, or if the contractor's equipment or methods dictate, the schedule should incorporate anticipated adverse weather for the historically prevalent weather conditions in that region given the equipment being used and work being performed.

Upon acknowledgment of the Notice to Proceed (NTP) and continuing throughout the contract, the contractor will record on the daily CQC report, the occurrence of adverse weather and resultant impact to normally scheduled work.

Any claim for delay due to unusually severe weather must be submitted in accordance with FAR Clause 52.249-10 Default (Fixed-Price Construction).

Include sufficient documentation to facilitate review by the Contracting Officer.

1.3 PARTNERING

In order to most effectively accomplish this contract, the Government proposes to form a partnership with the Contractor to develop a cohesive building team. It is anticipated that this partnership would involve the Contractor, primary subcontractors and designers, and the Corps of Engineers. This partnership would strive to develop a cooperative management team drawing on the strengths of each team member in an effort to achieve a quality project within budget and on schedule. This parntership would be bilateral in membership and participation will be completely voluntary. The partnering meeting shall be held at agreed upon dates/times of all involved parties. The meeting will be an informal, non-facilitated meeting and can be combined with the preconstruction conference.

1.11.1 Debris Management Plan

The Contractor shall submit a detailed plan indicating the actions that will be taken to mitigate man-made debris from reaching final placement at the specified placement area. The plan shall include that documentation of all site conditions/findings and actions taken to mitigate placement of man-made debris be entered in the daily quality control reports in RMS. The Contractor shall ensure that dredged material is free of metal prior to completion or allowing the public to access the placement area, whichever is sooner.

1.11.1.1 Mechanical Placement

If the Contractor elects to utilize mechanical equipment as means to place dredged material, the Contractor shall at a minimum utilize the following practices for minimizing placement of man-made debris, unless otherwise

SECTION 01 35 13 Page 11 approved by the COR.

a. During the dredging and placement operations, the Contractor shall continuously and closely monitor the material being collected from the dredge areas and placed in the identified placement area for man-made debris. The contractor must routinely utilize metal detecting equipment to monitor placed material for man-made debris. Any man-made debris observed within the dredged material shall be immediately removed either from the scow/material transport vessel or immediately after placement and appropriately discarded off site at no additional cost to the Government.

c. During placement operations and final grading of material at the specified placement area, the Contractor shall continuously and closely monitor the material being graded for man-made debris. Any man-made debris observed within the placement area shall be picked up and appropriately discarded off site at no additional cost to the Government.

d. If man-made debris is encountered, the Contractor shall immediately notify the COR and cease operations. Operations shall only proceed upon receiving approval through the COR. The Government reserves the right to enforce additional debris management requirements if current requirements are deemed by the Government to be insufficient.

1.11.1.2 Hydraulic Placement

If the Contractor elects to utilize hydraulic equipment as means to place dredged material, the Contractor shall at a minimum utilize the following practices for minimizing placement of man-made debris, unless otherwise approved by the COR.

a. During the dredging and placement operations, the Contractor shall continuously and closely monitor the material being collected from the dredge areas for man-made debris. The contractor must routinely utilize metal detecting equipment to monitor placed material for man-made debris. Metal detection monitoring must be focused within the vicinity of the point of discharge. Any man-made debris observed within the dredged material shall be immediately removed from the scow/material transport vessel and appropriately discarded off site at no additional cost to the Government.

b. Use of hydraulic conveyance methods for material transport shall incorporate a screening process with maximum grid openings of 2 inch by 2 inch capable of effectively capturing man-made debris prior to material being placed at the Minnesota Point North Placement Area. The Contractor shall regularly check for and remove debris that has been restrained from reaching the placement area. Any man-made or natural debris captured by the required screening process shall be removed and appropriately discarded at no additional cost to the Government.

c. If man-made debris is encountered, the Contractor shall immediately notify the COR and cease operations. Operations shall only proceed upon receiving approval through the COR. The Government reserves the right

SECTION 01 35 13 Page 12 to enforce additional debris management requirements if current requirements are deemed by the Government to be insufficient.
