1. SOW/Technical Specification/Drawings paragraph/page _Spec 32 92 23 and Dwg E506___

Question: _What are the requirements for site restoration for the areas where duct bank is being installed and where poles are being removed? Specifications are provided for sod only.

Answer: Bring site back to original condition with either sod or seed. Grass needs to be established before government will accept.

2. SOW/Technical Specification/Drawings paragraph/page _ED 101 Flag Note 2_________

Question: Drawing ED101 indicates that the line being removed by Flag Note 2 is underground electric. Flag Note 2 indicates that this is overhead electric. Please clarify.

Answer: Section of Flag Not 2 is underground. Circuit transitions from overhead to underground at pole 37-55A

3. Item # 1 Repair F line

SOW states The duct bank will be placed between existing Manholes 211 and 212. Drawing EC- 103 shows going to MH2314

SOW states “Pull cable from switch 3N5 to 3N7 to transformer CX32I1. Drawings seem to indicate transformer CX34I1

Answer: Ductbank between MH 2314 and MH 212. Pull cable from existing switch 3N5 and new switch 3N7 to transformer CX34I1. Also picking up transformer MOTR as per design drawings. CX32I1 should read CX34I1

4. Item # 2 Repair J line

SOW says to (Pull new 4/0 cable from existing switch 3N6 through manhole 2314 to existing switch

CC617 and through existing manhole 2474. Drawings seem to indicate existing switch CCCG17.

Routing is unclear from MH2474 to MH2475, however the cost will be similar between the east or west duct banks 10W6, assuming there is a spare conduit in either.

Answer: pick up CCCG17 by splicing into MH 438 on the corner of Central Control Rd and ICBM road.

5. Item # 3 Radiographic Tests

SECTION 26 05 13.00

Perform and submit radiographic tests on all splices/terminations at the discretion of the Contracting Officer to determine if voids exist. Rework unacceptable cable, splices or terminations at no additional expense to the Government.

Need clarification. X-Ray testing is quite expensive. High-pot testing determines the acceptability of failure of splices and terminations, and is also required. What is meant by “at the discretion of the contracting officer?”

Answer: Use very low frequency (VLF) Testing. X-ray testing is not required.

6. Item # 4 Excavations

SECTION 01 11 00.00 30

19 Apr 17

3.5.2 Restrictions

All excavation at the work site must be accomplished by hand only.

Excavating machinery is prohibited.

Hand digging is required within five feet of located underground utilities.

Need confirmation that all excavation is by hand – no backhoe or other machinery?

Answer: Machinery is acceptable to use. Hand dig within five feet of located underground utilities.

7. Item #5 Pole Heights

Of the poles that are to be removed, what is the length of the concrete poles? What is the length of the wood poles?

Answer: Concrete poles are 60 feet. Wood poles are 50 feet.

8. Item #6 Contaminated Soils

Can any of the contaminated soil be reused? If yes, is there a location on base where any excess soils can be delivered? Is there a location on base from which we can “borrow” fill dirt? If yes, what is the approximate distance between the work area and the spoils/borrow site?

If contaminated soils cannot be used, what is the disposal protocol?

Answer: reuse all soil no soil needs to be disposed of off base. There are locations on base to borrow fill dirt but we cannot guarantee they will be available at the time of construction. Contractor should bid accordingly.

9. Item #7 Copper Credit

01 11 00.00 30 1.2.1

Contractors bid shall clearly indicate amount of credit being provided for copper conductors being removed from this project.

Are all overhead conductors being removed, including static lines, hard-drawn copper?

Are all underground conductors being removed soft-drawn copper?

Answer: Static line is hard-drawn copper. J-line (second line on ICBM road) is Paper and aluminum conductor cable. The rest is a combination of hard-drawn and soft-drawn copper. Include the amount of credit being provided (if any) in your CECC Form 3052 (or equivalent) cost estimate breakdown (Reference solicitation Section L). Any credit should also be reflected in your bid amount. Evaluation of Bids and Basis of Award will be as stated in Section M.

14. RFP Section __F ______ Paragraph __”Deliveries and Performance”_______ SOW/Technical Specification/Drawings paragraph/page __5 of 38_________

Question: Deliveries and Performance paragraph missing? Neither the IFB nor the specifications state the number of no-dig/non-access days in which will occur during the 740-day period of performance. With our history of projects containing a period of performance such as this one the no-dig/non-access days can very easily exceed 150 days. After your review please advise accordingly.

19 Apr 17

17. SOW/Technical Specification/Drawings paragraph/page Drwg. Multiple Notes

Question: _Within the drawings there are multiple notes stating “Groundwater Plume is known to contain Chlorinated solvents” Are the exact type of contaminates known for hazmat training and PPE requirements?

Answer: The SLC-16 groundwater plume (in the area along ICBM Rd) includes both vinyl chloride (VC) and cis-1, 2-dichloroethene (DCE) at concentrations above regulatory cleanup levels. This is based on several DPT locations and monitoring wells that have been sampled near the roadway. Exceedances have been observed in several depth intervals in this area, to include as shallow as 5-10 ft bls.

The LC34 groundwater plume (in the area along Freedom Rd) includes Trichlorethene (TCE), cis- 1,2-dichloroethene (DCE), and vinyl chloride (VC) at concentrations above regulatory cleanup levels.

This is based on numerous DPT locations and monitoring wells that have been sampled near the roadway. Exceedances of groundwater criteria begin at the water table and continue to a depth of 38 feet below land surface in the area.

18. SOW/Technical Specification/Drawings paragraph/page _EC-110 Flag Note 1_________

Question: _EC-110 Flag Note 1 specifies a “concrete-encased horizontal directional drill 4W5 ductbank” approximately 375 ft long to be installed under an area of standing water. Please clarify that this is actually supposed to be concrete encased. If so, please provide a detail of the concrete-encased HDD duct bank.

19. SOW/Technical Specification/Drawings paragraph/page _01 57 19 Section 3.11 & G-003 General Note 9__

Question: G-003 General Note 9 specifies the excess and surface blowout drilling fluids shall be collected and disposed off-site. Throughout the drawings, it is noted that, “groundwater plume is known to contain chlorinated solvents” and certain areas are, “known to contain soils with PCB above residential soil cleanup target levels.” Will the Government require analytical for characterization of all excess surface blowout drilling fluids to be disposed of? If so, will the Government be providing the analytical service or should the contractor include this service in his estimate?

Answer: In plume areas containerize blowout drilling fluids and have it tested to determine the appropriate disposal methods. Cost should be in contractor’s proposal. If it's hot, our environmental group will dispose of. If not Contractor will have to dispose of.

20. SOW/Technical Specification/Drawings paragraph/page _01 57 19 Section 3.11 __________

Question: If analytical of the excess surface blowout drilling fluids to be disposed determines these to be hazardous waste (i.e. elevated levels of PCB or chlorinated solvents), is this required to be disposed of off-site or turned over to the Government?

Answer: Turned over to Government

21. RFP Section 26 13 19 .01 Paragraph 2.5

Question: Just so we are on the same page, this paragraph says cabinets shall be equipped with mounting plates that allow installation of industry standard dead-front three- or four-way junction modules and elbows conforming to IEEE 386. Most applications in this project do not need that many modules. Is it allowable to just install the modules as needed on the full size mounting plate?

Question: Please confirm what Junctions are required in each of the Sectionalizing Cabinets.

Spec section 26 13 19.01 2.5 calls out either three or four point junctions. Cannot locate a detail to show which to use. Should they all be assumed to be 4 way? In all cases they appear to be for inline feeders; so assume all would be 600A? Bushing height shows to be 24 inches, is this correct?

Answer: minimum of three junction modules per cabinet all 600A. 24 inches is correct.

36. Question: _When removing the “J” line conductor, does the messenger and the clips that hold the conductor on to the messenger have to be removed separately, or can the messenger and the 3 conductor cable be rolled up together?
