Scope: Screening of Concrete/Dirt Stockpile, Concrete Crushing and Stockpiling
Set up of equipment and the processing/crushing operation shall be coordinated with the Landfill Manager. The project shall be set up or operated in a location where it shall not interfere with daily operations of the Landfill.
Mobilization of Equipment
Contractor shall quote a lump sum price to mobilize & demobilize appropriate equipment to screen the existing stockpile of concrete/dirt into various sizes and to crush larger pieces into ¾ inches. This price shall be inclusive of any and all permit, fees and/or rentals needed to stage the equipment at the Landfill. The Landfill operating hours for moving equipment in and out are typically 6:00 a.m. to 2:30 p.m. For the purpose of this Bid item, assume that mobilization/demobilization can take outside of the normal working hours, including on Saturday, provided appropriate arrangements are made in advance with the Landfill Manager.
Concrete Stockpile Screening
Contractor shall provide a per ton yard rate for the labor and equipment the contractor deems necessary to screen/segregate concrete from the stockpile at the California Street Landfill. Upon further examination it appears that the current stockpile is heterogenous and contains estimated 35% to 45% dirt in and a wide variety of concrete chunk sizes, with and without reinforcing metal. It is expected that the Contractor, upon examination of the current stockpile, will be able to identify the most effective means of processing the stockpile.
Explosives and blasting are not permitted in the performance of the pre-processing work. Work shall comply with the Landfill’s Storm Water Pollution Prevention Plan. Residual metal concrete reinforcement materials that are recovered shall be managed by the City of Redlands Landfill staff.
The Contractor shall ensure the work area affected by the stockpile screening will not allow ponding of water.
Concrete Crushing
Concrete pieces regardless of size are to be crushed. Concrete is to be crushed to produce one size of material for use in landfill road building. The Landfill fill desires material that is the following size:
• ¾ inches
The estimated quantity used for bidding is not a guarantee on the amount of material that is actually on site. The Landfill may, at its discretion based on need and/or available funding, increase or decrease the quantity of material to be produced.
Payment will be on a per ton basis. Total tons produced shall be documented by the contractor. The Landfill reserves the right to verify tonnage and quantities via the on-site landfill scales and/or volumetric survey of the final product piles. Daily belt scale tickets are to be provided to the Landfill Manager.
The Contractor shall document and certify any material provided under this bid item is not contaminated by nor contains asbestos, asbestos containing materials, solid waste, infectious waste, hazardous waste or construction/demolition material (i.e. wood, shingles, drywall, etc.).
