Repair Water Mains and Roads
W50S9A‐20‐B‐0001
Questions and Answers
1. Question: Mustang and Patriot projects indicate removing the underlying materials under the asphalt to get to the sub‐base. Sabre street plans only indicate to remove the existing asphalt 4‐5” in depth according to the Geotech report. The Geotech report refers to the underlying material to be silty sand. Please clarify if the underlying material needs to be removed under the existing HMA on
Sabre Street.
Answer: See updated Sabre Street Drawing C‐02.
2. Question: The SLC dump is requesting the Phase 1 Environmental Site Assessment (ESA) to determine if the soil is chemically clean. Is this something that has been completed?
Answer: The government is way past a phase I ESA on these sites and past the Remedial Action phase on both sites and into Post Construction Completion. Since the sites are not officially closed, the maps provided on the 27 Aug 2020 IRP Summary document were from the latest Groundwater
Long Term Monitoring Reports. These documents may be viewed in their entirety on the public administrative record at https://ar.afcec‐cloud.af.mil/ (Select the ANG radial, highlight Salt Lake City
Int APT, UT, and then click search for the list of records).
The sample results on the maps provided mark the latest concentrations in groundwater. The contractor can use these numbers or conduct their own sampling of the soil to provide an accurate special waste profile for the landfills.
3. Question: Is there a domestic steel/iron requirement on this project? If so, what requirement do we need to meet (AIS, Buy America, Buy American, etc.)?
Answer: See FAR Provision 52.225‐10 and FAR Clause 52.225‐9.
4. Question: The specs (Environmental Concerns) states that water must be containerized and can be returned to the site. If this is the case and we don’t haul it off to dispose of it, it would be a lot more cost effective. There are containers that filter the water before they are discharged onsite. As the specs states, can we containerize the water and return it to the site? This is based on the assumption that we will be in ground water when installing the utilities.
Answer: IRP Summary (Environmental Concerns) has been updated to be clearer. Regulation allows for the contaminated water to be returned to the site, but this project is stricter than regulation and requires off‐site disposal. See updated IRP Summary (note difference between water from contaminated zones and non‐contaminated zones) and Mustang Dwg G‐04 Note 45.
