Also included in the section is the removal of undesirable vegetation such as invasive species plants that might establish among the new plantings and also wrack (rafts of dead vegetation) that might potentially float ashore.

The Contractor must containerize the collected debris rather than merely stockpile it within the project area. The container must be of a known volume and must be emptied upon reaching capacity. At a minimum, on a weekly basis and after a significant storm or tidal event, or at the request of the Contracting Officer, the Contractor shall inspect the project site for floatable debris and undesirable vegetation, and shall immediately collect and containerize any such material.

Within 15 days of the Notice to Proceed, the Contractor must provide a Debris Removal Plan that describes how he intends to containerize and dispose of the debris, including submitting a notice of intent from a licensed upland disposal facility, which confirms that the facility will accept the material.

Under this section, the Contractor shall clear and remove all objectionable material including trees, shrubs, brush, vines, standing common reed (Phragmites australis) and wrack, stumps of all sizes, weeds, stones, wood, tires, and trash. This material shall be removed from within the limits of the Work Site Access Road, Staging Area and Restoration Area, the top 6 inches of loose surface litter, organic litter, Phragmites sp. rhizomes, consolidated material, leaf litter, and other organic debris. This material shall be removed from within the limits of the Clearing Area, in accordance with the plans and specifications, and the direction of the Contracting Officer.

The Contractor shall carefully protect all preserved areas as shown on the plans, and shall also be liable for any and all damages to property caused by the work under this section. Any damages to property or to vegetation within preserved areas shall be restored to the original conditions to the satisfaction of the Contracting Officer.

All organic material and Phragmites Austrailis wrack cleared under this section shall be disposed of first, prior to any excavation activities, at an off-site disposal facility approval by the Contracting Officer. All

d. Covering and other means shall be provided for maintaining the concrete at a temperature of at least 50 degrees Fahrenheit for not less than 72 hours after placing, and at a temperature above freezing for the remainder of the curing period.

1.5.2 Placing During Warm Weather

The temperature of the concrete as placed shall not exceed 85 degrees F ahrenheit except where an approved retarder is used. The mixing water and/or aggregates shall be cooled, if necessary, to maintain a satisfactory placing temperature. The placing temperature shall not exceed 95 degrees F ahrenheit at any time.
