FA461326Q0020 Stockpile Removal

Questions and Answers

1. Material Segregation & Sizing: Are the concrete and asphalt stockpiled separately in clean individual piles, or are the materials co-mingled within the stockpile? Additionally, is the debris already broken up into manageable pieces?

Govt Response: The one major concrete pile is broken down into manageable pieces that can be loaded with a bucket loader and hauled/transported. The second and third pile consists of asphalt that is a blend of large, medium pieces and millings that have compacted naturally over time. The fourth pile is mostly concrete with some asphalt material. This pile would need to be broken down and filtered. See Attachment 7 for Stockpile Photos.

2. Foreign Materials / Rebar: Does the concrete debris contain embedded rebar, wire mesh, or other structural steel/foreign contaminants?

Govt Response: We have thoroughly gone through pile one and broken down the concrete and removed metal debris. In the event, debris is identified during loading, the Contractor shall remove this small percentage of concrete/metal debris and set aside to be broken up later time. It will still be the contractor’s responsibility to dispose of these metal debris, however, they see fit. The Government shall pay to dispose up to 130 loads (each about 12- 14 cubic yards on a 15-ton dump truck) for a total of about 1,820 cubic yards. Contractor shall have weight delivery tickets provided to make sure minimum load per dump truck is met. Anything exceeding 130 loads shall not be the responsibility of the contractor.

3. Site Photos & Footprint: Due to unavailability for site visit, can the Government provide representative site photos (wide-angle showing footprint/yard access, plus close-ups of material composition) along with approximate pile dimensions?

Govt Response: Pile 1 – approx. 2500 cu yds Pile 2 & Pile 3 combined – approx. 4,000 cu yds Pile 4 – no numbers or pictures. It is mixed material and we will hit our 1,300 cubic yard cap prior to touching pile 4. Photos available but no estimate of cu yards. Total cubic yards for all four stockpile is about 8,000. However, the Government, under this solicitation, is only requesting up to 130 loads of 12-14 cubic yards each (on a 15-ton dump truck) which brings to about 1,820 cu yards. Anything in excess of 130 loads shall not be the responsibility of the contractor.

4. Loading Operations: Who is responsible for loading the concrete and asphalt material into the haul trucks at the site—the contractor or Government/base personnel?

Govt Response: The Contractor is responsible for loading all stockpile into haul trucks and disposal thereafter, up to 130 loads of 12-14 cu yards on a 15-ton dump truck.

5. Governing Quantity Basis: CLIN 0001 identifies 130 loads, an estimated 1,300 cubic yards, and a maximum of 1,600 tons. If these three metrics produce differing totals during execution, which metric strictly governs payment and contract completion?

Govt Response: The Contractor shall have weight tickets to provide proof of each load. The contractor should provide the cubic yard capacity of the haul vehicle(s) to help determine when we get to the estimated 1,820 cu yards for a 15-ton dump track capable to hold 12-14 cu yards of stockpile. A maximum of 130 loads is set under this service. Anything in excess is not the responsibility of the Contractor.

6. Payable Load Specification: The solicitation states that each load must meet the expected weight of a truckload. What specific truck configuration, minimum volume, or target net weight will the Government use to define an acceptable, payable load?

Govt Response: The contractor will use suitable hauling equipment within DOT guidelines and regulations. A payable load will consist of filling the haul truck/trailer to the cu yard capacity of that given asset. It is anticipated that a 15-ton dump truck capable of hauling 12-14 cu yards of debris per load, can meet a 130 load or up to an estimated 1,820 cu yards of debris.

7. Recycling & Final Disposition: While the PWS cites legal disposal at an authorized off-base site, environmental specifications address RCRA Subtitle D diversion. May clean concrete and asphalt be delivered to a permitted aggregate recycling facility as its final disposition, provided certified scale receipts are furnished?

Govt Response: In accordance with 1.1.4. of the PWS, as long as the concrete is disposed of properly in accordance with local, state, and federal laws. Therefore, a recycling center that is permitted to recycle these materials under those mandates would qualify, as long as the contractor adheres to the weighing requirements and submits weight delivery tickets as proof of meeting the number of loads allowed under this requirement.
