A28: See question 25.

Q29: Is all the soil considered contaminated or is there only isolated areas?

A29: VA is unaware of any soil in this project that can’t be reused as fill. See specification section 31 20 00 Part 3.5 DISPOSAL OF UNSUITABLE AND EXCESS EXCAVATED MATERIAL Q30: Per Section 31 20 11 Part 3.5-E conflicts with Part E referenced above. Please clarify?

A30: Section 31 20 11 not part of this project. See section 31 20 00. The above references Part C gives information on “stockpiling,” Part D gives information on when excess excavated materials suitable for fill and/or backfill may be disposed of, and Part E gives instructions on how to dispose of it.

Q31: Can any of the “contaminated” soils designated by the Resident Engineer be used as backfill?

A31: Yes, in compliance with specification 31 20 00. VA is unaware of any soil in this project that can’t be reused as fill Q32: Will the VA provide direction as to when the stockpiled contaminated soil is to be removed and where it is to be taken to?

A32: See question 30 Q33: Is there a Soil Profile showing the levels of contaminates for this project and will it be provided? If not, where should we figure the contaminated soils need to and will the VA be providing that paperwork showing compliance with all State and Local requirements?

A33: See specification 31 20 00 3.5 E and F Q34: Will the contractor be responsible to carry in their bid and pay for the tipping fees associated with the disposal of the contaminated soils?

A54: Minimum clearance is 42” between generator and walls

Q55: Are any new foreseer meters to be installed under this contract?

A55: Yes, there should be two; one for the ATS and one for the new panel DH-SB-BLD112-1 Q56: Is the contractor responsible for providing fuel for the temp generator?

A56: Yes, all equipment and supplies necessary for the running and connection of the temporary generator are to be provided. See phasing schedule sheet E-001.s

Q57: Are MV outages to be done on a certain day of the week?

A57: Yes, Sundays

Q58: What termination type will need to be used to attach to the existing MV system? Are we to assume MV connection is allowable under existing conditions without modification of the existing system?

A58: MV conductors to be spliced into existing MV conductors at MV Switch being removed, sheet E-001 phasing 1.a. Termination to equipment will be dependent on the type of equipment submitted.

Q59: Is there a BoD for light switches?

A59: No, there is not a BoD for light switches, but if new switches are added they must be similar to, and work with, the existing switches in the same area, i.e., 3-way switch.

Q60: Electrical General note 18 on page E-001 states that no set screw fittings are to be used, does this pertain to ALL trade sizes?

A60: Specification 26 05 33, 2.1.C.2.c indicates that compression fittings are to be used for 3/4” to 2” and set screw hardened tip for 2-1/2” to 4

Q61: Can you please confirm the generator size? The one-line e-601 states the new generator is a 600kW but the specification sheet page 6 calls for a 400kW.

A61: See attached, revised specification section 26 32 13 Q62: Currently, below specification (07 27 26) calls for FLUID-APPLIED, VAPOR PERMEABLE regard to above project. We would like to request that our AIR-SHIELD LMP please reviewed as a liquid membrane vapor permeable material here.

A62: From what can be seen about the W.R. Meadows product it appears that it would meet the requirements for this project, but a full submittal per the requirements of the contract documents was not provided and further evaluation cannot be performed.

Q63: Please provide the following report per the structural notes: "FOUNDATION DESIGN IS BASED ON THE RECOMMENDATIONS IN THE GEOTECHNICAL REPORT PREPARED BY TERRACON, REPORT NUMBER 58215015 DATED 10 MARCH 2021." We will need this to estimate type of helical pile, depth, flight configuration etc.."

A63: See attached Geotechnical Report Q64: Please clarify the ASTM spec to be used for the load tests referenced on the Structural Notes. "A MINIMUM OF TWO LOAD TESTS SHALL BE MADE. PIERS SHALL BE TESTED FOR 2x THE ALLOWABLE LOAD CAPACITY. ALLOWABLE LOAD, CAPACITY OF A SINGLE HELICAL PIER SHALL BE 6,000 POUNDS MINIMUM."

A64: See ASTM D1143 Q65: If ASTM Static load tests are specified, the cost will be significant due to the reaction piles that will need to be installed, test frame setup etc... Please keep in mind there are only 4 helical piles on this job designed for an allowable load of 6k per pile and will be designed in accordance with IBC for a 2.0 safety factor. It is our professional opinion that the requirement for 2 load tests is excessive and can be eliminated for cost savings measures considering the quantity and light load per pile. Please consider eliminating this requirement.

A65: Helical pile testing is not required. Piers shall be designed with a 3.0 safety factor, in lieu of testing.

Q66: Spec section 23 05 93 Testing, Adjusting and Balancing for HVAC is included in the specifications section. But there are no air distributions systems to be leak tested or balanced. The only duct work on this project is the exhaust duct for the new generator. Is the Specification section 23 05 93 needed for this project? If so, what scope of work should they be including?

A66: Confirmed, Spec section 23 05 93 Testing, Adjusting and Balancing for HVAC is NOT required for this project

** Additional VA Responses to vendor questions/RFI’s are forthcoming.
