1. How deep are existing electrical lines, fiber line and electrical duct bank?

A: Reference the attached topo survey PDF. Please be advised that depths are approximate, and this survey did not locate all existing underground utilities. Approximate depths of utilities located by GPR are noted as “D=_”. All utilities shown on attached TOPO and included on plan drawing sheets shall be physically located within the areas of work prior to excavation for installation of new fuel lines and other structures. Contractor to physically location all utilities in area of work prior to any excavation work.

2. Are steam lines within a concrete tunnel? If so how far below ground is the tunnel and what is the top and bottom elevation? If not, what size are they, what depth are they buried and how many are there?

A: Please reference the topo survey and design drawings for approximate depths and quantities.

Known steam lines have been found to be direct bury.

3. What is the depth of the existing and new relocated waterline? What size is the waterline and what type of material?

A: Please reference the topo survey and for approximate depths. Existing piping is 8” nominal size. Material is presumed to be iron.

4. Amendment 002 appears to have been posted on 10/31… will amendment 001 be forthcoming?

A: Amendment one was a internal system change that reflected the same information as on Amendment 002.

5. CE101-S road closures: How long can the contractor close Bradford Pear Lane and S. First

St.?

A: It is the intent of the design to close these roads one at a time to allow traffic detours and provide continued access to the Sani-Pack, Bldg. 205 (Loading Dock/Warehouse), Bldg. 207 (PET/CT), and Bldg. 214 (MRI). Closure of these roads should be limited to only the time necessary to demo, excavate, install, test, backfill, and re-pave. Contractor will have to provide 24hr traffic controls and detour signage when either section is closed. Contractor should plan for an estimated 2-3 week’s maximum per. road crossing. Temporary protection of crossing measures for excavation meeting H-20 loading will be allowed when necessary.

6. Spec. 23 10 00/ 1.5/ E: "E. Tank and piping installation contractor shall be certified as acceptable by local and state pollution control authorities." 1) Which specific authorities/ agencies? 2) What specific certifications are required?

A: Any contractor performing the installation of new aboveground fuel oil storage tanks (ASTs) and fuel oil supply distribution piping shall be a certified “UST Corrective Action Contractor” through the Tennessee Department of Environment & Conservation (TDEC). This is due to the fact that the NEW ASTs will be replacing the existing underground fuel oil storage tanks (USTs).

7. Spec. 23 10 00/ 1.5/ A: "A. Contractor shall obtain and complete all tank permit and registration forms required by governmental authorities." 1) Which specific authorities/agencies? 2)What specific permits are required?

8. Fuel oil: Will the contractor be required to provide any fuel oil as part of this contract? If yes how much?

A: As part of the contract, the contractor will be responsible for the transfer and polishing existing diesel fuels in underground (USTs) storage tank to new aboveground (ASTs) storage tanks. The VA currently uses the local Stowers/CAT dealer for these services. The VA will be responsible for additional fuel needed to “Top Off” new tanks toward the end of the project.

Coordinate fuel delivery with the VA.
