I am requesting access to the Plans for the above subject Project.

I have completed DD Form 2345 and FedEx mailed to the DLA this morning. However, I am concerned that the required DLA approvals will not be processed in order for me to obtain the plans via FBO.

SOW, plans, and specs have been sent via AMRDEC.

19 Jul 2018 N/A 19 Jul 2018 See answer below 19 Jul 2018

I am trying to download the rest of the Bid package and for some reason the FBO system isn’t able to verify our company MPIN number. I have verified it through SAM it is the correct number I am not sure why it wont work on the FBO site. Is there another way to get the drawings?

Or do you know what I need to do to verify the MPIN number is correct?

19 Jul 2018 N/A 19 Jul 2018 See answer below 19 Jul 2018

Are you the person who can grant access to the documents regarding this project on FBO?

Yes, along with SMSgt Kyle Kiepke and Ms. Kerry Wells.

19 Jul 2018 19 Jul 2018 24 Jul 2018 See answer below 13 Aug 2018

Can you confirm there are only 6 sheets of drawings for this project.

The SOW and notes on the plans insinuate that there is work for exterior lighting and there may be a lighting plan associated with the

Lighting Plan added and attached as “H01 Lighting Plan” project. We have not received a lighting plan in this package. Please advise.

NOTE: In the vicinity of Granville Ave crossing South Outer Road, near the existing running track, there used to be a steam treatment facility. The possibility exists that there is some underground piping from that former plant location (near existing water tower no. 3) crossing the roadway and located several feet down (min 4 feet). Some of that piping may have Asbestos Containing Materials (ACM). This is HM and shall be disposed of properly by the contractor. Contractor shall make every effort possible to avoid any existing piping in that area that may have ACM when performing underground primary work. There are no plans readily available that shows actual locations of the former steam generating facility. (SEE RFI NO. 66 below)

REMOVE: Hazardous materials will be removed by Owner before start of the Work. If suspected hazardous materials are encountered, do not disturb: immediately notify Architect and Owner. Hazardous materials will be removed by Owner under a separate contract.

ADD: Contractor shall be responsible for the proper disposing of asbestos containing material, (ACM) found as a result of digging in the vicinity of Granville Ave crossing South Outer Road, near the water tower and running track. That area, in the past, was a steam production plant. There may be underground piping that has ACM pipe lagging. Contractor shall make every effort to avoid those areas when performing the underground primary work. Contractor shall be responsible for proper disposal of HM disturbed as a result of excavation. (SEE RFI NO. 66 below)

59.) Section 015000 Temporary Facilities and Controls, Paragraph 3.3.1.4 REMOVE: Coordinate elevations of temporary roads and paved areas with permanent roads and paved areas.

ADD: Provide temporary access road for federal/military employees to use to go to their respective buildings while construction of the underground work is taking place.

SEE “lighting section and perimeter loop” (H01 Lighting Plan) Spec That document describes the Contractors Responsibility to produce the lighting design And construction

16 Aug 2018 16 Aug 2018 22 Aug 2018 See answer below 22 Aug 2018

Page 12 of Section 265600, issued with Amendment 01, contains a map. On the map it states "Remove and Replace with Sidewalks" with bold dark lines and bold green lines. Is this map simply to show the area or work or something else. Are we to remove and replace sidewalks? If so, what are the bold black lines and bold green lines indicating?

This map is shown in Section 265600 LIGHTING to indicate the areas that are to get new lighting. Contractor shall use this layout to prepare lighting plans for the project. There are no sidewalks to be “Removed & Replaced” as part of this project.

Do not consider the dark black line and green line as part of this project. Use the plan to assess locations for new lighting.

Section 265600 para 1.2.2 discusses the need for "primarily street lighting and other areas shall require sidewalk illumination." However, it also states "Also, provide for exterior lighting for ne "Perimeter Loop" layout per attached plan." What is meant by "Perimeter Loop"?

Are the forty-five (45) exterior street lights and additional eighty-five

(85) exterior sidewalk illumination pole mounted fixtures mentioned in this paragraph additional as part of the "Perimeter Loop" or are these

(45) street lights and (85) sidewalk lights estimates of what will be needed in total for the entire project inclusive of the "Perimeter Loop", streets and sidewalks in the work area?

Paragraph 1.2.2 says: “…..Also, provide for exterior lighting for new “Perimeter Loop” layout per attached plan. Provide for approximately forty-five (45) exterior street lights where designated by lighting professional design. Provide for an additional forty-five (45) exterior sidewalk illumination pole mounted fixtures.”

That’s a total of ninety (90) overall lighting fixtures that are intended to be included for all of the lighting for the work area based on a lighting professional design that is to be accepted by CES and Base Commander. The Perimeter Loop is the area that’s going to be revised by Civil Engineering. CES will be changing sidewalks, etc.

Please refer to Q&A #40, #57 and #58. Please provide a LF of asbestos piping removal to be carried for the purpose of this bid. If there is no known information provided for the contractor, how is the contractor supposed to provide an accurate competitive bid? Could this be handled as an allowance in the bid?

As a follow up to the reference of asbestos pipe lagging on old steam plant piping, it has since been determined that there was no asbestos containing material (ACM) on any of the outside piping that originated from the old steam plant. The asbestos HM was only located inside the plant itself and has since been removed over 15 years ago. For purposes of this contract, there is no need to include any associated cost for asbestos removal in the vicinity of the project associated with the old steam plant. It’s also been determined that piping associated with the former steam plant was located in excess of 15 feet below grade.

Please clarify Answer 60 Note to bidders. Are the soil borings required to classify the soil or to locate the underground utilities. Is the intent of

Contractor shall be responsible for soil borings to assist him/her in locating underground equipment. You’d want to know if you’re dealing with heavy rock material or soils that this note to say the contractor id responsible for all "potholing" to locate existing utilities? It is confusing because utility locating and removal and replacement of soils don't have anything to do with one another.

can easily be removed when locating manholes, etc. Not doing soil borings is the contractor’s prerogative.

Regarding the lighting plan: It is cut off and it is color coded but doesn`t tell us what colors mean.

RFI #44 response confirms that Pole R3 cutouts are to be refed from SGR-2. This will require a 15KV switch / fuse position at SGR-2 to be the source for refeed to Pole R3. The Electric One Line Plan does not show this refeed. Is this feed to share a position on SGR-2 or does SGR- 2 need an additional switch / fuse position added?

SGR-2 will require an additional switch/fuse position added

Note #15 on Existing Removals Plan states “Provide new Riser at this pole (OC-23) from underground primary Switchgear..” This will require a 15KV switch / fuse position at SGR-6 to be the source for refeed to Pole OC-23. The Electric One Line Plan does not show this refeed. Is this feed to share position on SGR-6 or does SGR-6 need an additional switch / fuse position added?

Bid form only has two items for the project on the solicitation. As part of Addendum #2 we are asked to provide 3 light fixture options which have different costs. How should these be presented on the form?

Bids shall have a lighting option included that has been identified in the plan as acceptable. Multiple lighting options are not necessary.

Should we carry the lowest in our bid and inched a sheet with the adders for the others?
