QUESTIONS AND ANSWERS

Upon review of Specification 26-42-13, section 2.07.F says to (Equip [the junction box anode circuits] with variable resistors” As potential material suppliers with no CP design liability, Farwest would need to know the required resistance and current capacity (watts) of the requested resistors. Drawing # 33-D- 61718 gives no answer to this question (reference Galvanic Anode Junction Box Detail).

The Contractor shall determine via tests during commissioning if a resister is required. If required, variable resistors are typically slide resistors and can be sized as 5 ohm - 25 Watt. Contractor shall ensure adequate space is provided in the box for mounting these resistors.

Is it possible for us to meet someone on site who will have keys to these areas (Interior of Generator Building and equipment on the dam behind gates) so we can investigate some of this equipment and determine the full scope? We would also like to visit the Yakima field office to learn more about the existing control workstation and what software is being used on it, if we are able too.

The Government will not schedule a second site visit to address this question. However, the Government has provided pictures of the site that could address offeror concerns regarding this question.

11 1. In Section 28 10 01, Part 2, 2.02, calls out for a protective cage that is SS. Can you provide acceptable examples of cages, or describe what protection functions the cage needs to provide?

Specifications Section 28 10 01, Security and Surveillance Equipment, paragraph 2.02, is the section for the PTZ Dome Cameras, so the stainless steel protective cage called out in paragraph 2.02 G.3 is to protect the dome camera. Contractor is responsible for choosing a stainless steel protective cage appropriate for the cameras proposed. The supplied manufacturer's data for the product should identify that it is a stainless steel protective cage for cameras in the supplied product literature.

12 2. What power circuit is the Power meter in Main Control Panel monitoring? Please confirm the point of desired monitoring.

The power meter in the Main Control Panel is monitoring incoming 3-Phase, 480VAC power. The existing meter is an Acuvim II multifunction power meter. Contractor is to provide a new power meter to replace the current one, as well as reconnect all current and voltage circuits to the new meter as required by specifications Section 25 00 01, System Control and Monitoring, paragraph 2.01 H, I, and J.

13 3. What is the SCADA/HMI software used on the existing workstation HMI at the Yamika Field office? There is no software used at the facility. It is a direct connection from Yakima Field Office to Clear Creek Dam (panel to panel via modems).

14 4. Is the project open to other forms of site-to-site communication to the site, like Satellite? No other forms of communication are acceptable.

15 5. If the leased phone line is the only acceptable or viable option for communications to the Yamika field office, please confirm that the VPN and firewall section of Division 25, section 2.12, are not applicable. These would only apply to any contractor provided network switches connected to the external communication circuit.

33 What CLIN is the road guardrail to be paid under? Refer to updated specifications Section 34 71 10, W-Beam Guardrail and Section 31 23 50, Earthwork for Road

34 Please confirm that the proposals will be opened and publicly read aloud according to the Solicitation, Offer, and Award.

This solicitation is being conducted under FAR Part 15 Contracting by Negotiation procedures. Therefore, proposals will not be opened and publicly read aloud. Offerors should familiarize themselves with Sections L and M of the solicitation for details on how the Government will select an awardee.

35 Fabric is called out as Galvanizing Before Weaving. This process will make it so that the top and bottom of the fabric will be exposed. I recommend Galvanizing After Weaving. Requirements in specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, shall be met.

36 Fabric coating is called out as Class 1. The weight for class one is 1.2 oz. Since this is a very wet environment, I would recommend Class 2 making the coating to be 2.0 ounce. Requirements in specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, shall be met.

37 Would it be acceptable for the pipe to be per ASTM F1043 Group IC? It is easier to get and less expensive than Group IA in the 50 kpsi.

Refer to updated specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, and specifications Drawing 33-D-61698.

38 What weight of galvanization will the pipe be? I would again recommend 2.0 ounce. Requirements in specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, shall be met.

39 Details show the cover to be welding. Will this require a certified welder? Will it be required to galvanize after welding or will cold galv paint be acceptable?

Refer to updated specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, and specifications Drawing 33-D-61698.

40 Is the design intent for the cover to be removable as the details show the cover sleeving into the posts? The intent of the design is not to be removeable. The sleeve component is there to simplify transportation of fabricated parts and constructability.

In Section 35 79 30 – Debris Boom Modifications, in Para. 1.01.A it mentions debris removal during construction. Can you clarify that this is only during the period of doing the boom modifications and not for the project duration? If it is for the project duration, we should be given some idea of what to expect.

Any debris that accumulates at the location of the reservoir structure and is in the way of construction activities will be the responsibility of the Contractor to remove. This is most likely during times the debris boom is not in place.

- Because of the location of the project and proximity of testing laboratories to perform ASTM D 5080 can this requirement be removed from the project specifications and satisfied with conventional nuclear density testing? In addition, with the requirement to perform 1 of these tests per day and every 500cy it is unlikely to see the test results from this back within 48-72 hours.

Place and compact backfill in accordance with specifications Section 31 23 02, Compacting Earth Materials, and Section 31 23 11, Earthwork for Structures.

- Due to the lack of equipment availability and certification to perform ASTM D 7382 in Washington state, can this requirement be removed from the project specifications and satisfied with conventional nuclear density testing? In addition, with the requirement to perform 1 of these tests per day and every 500cy it is unlikely to see the test results from this back within 48-72 hours.

Place and compact backfill in accordance with specifications Section 31 23 02, Compacting Earth Materials, and Section 31 23 11, Earthwork for Structures.

Factor 3 requires at least three PPQs to be sent directly to the Bureau of Reclamation. Factor 3 does not mention this, but the PPQ form requests a minimum of three Federal Government clients for whom it has performed similar services in the past three years. Is it required that the PPQ’s the Offeror requests have been performed within the past three years, or may we request PPQ’s for projects that have been completed within the last 10 years, as is requested under Factor 2, Section B (page L-8, or pg. 924/933 of Solicitation).

PPQs may be submitted for projects within the last 10 years as descried in Section L and M.

Dwg 33-D-61698 Notes and section 32 31 10-2.02.B indicate that Chain Link Cover pipes are spec F1082 Gr 50. Which is a pre-galvanized Fence material. The Cover Frames require rolling the Arch which could be detrimental to the Galvanized coating. This assembly also requires welding which again will require galvanizing repairs. Will ASTM A500 Gr B pipe be acceptable with Post-Fabrication Hot Dip Galvanizing in lieu of F1082?

Refer to updated specifications Section 32 31 10, Chain Link Fence and Chain Link Fence Cover, and specifications Drawing 33-D-61698.

Hendrick Screen Company has prepared a quotation for the fish screens found on the Clear Creek Dam Fish Passage Facility. We normally send out a copy of our quotation and scope of supply to the bidders on the project. I have searched the documents and was unable to find a plan holder or bidder’s list. Can you direct me to where I can access a list?

The Government did not generate a bidders list. Offerors should review the solicitation amendments for the site visit attendance roster.

47 Please consider extending the proposal date four weeks due to unanswered questions and extensive proposal level of effort. The proposal due date has been extended. Offerors should review solicitation amendment's for revised due date.

48 Are there any restrictions for pile installation using a drilling method adjacent to the dam? There is insufficient information provided to answer. Additional coordination via RFIs and VEPs will be considered after contractor award.

According to Sheet 77 , the turbine discharge centerline will be 7’-0” above the floor of the discharge weir. The elevation of that floor is 3013.50 according to Sheet 27, and the elevation of the floor slab that the turbine soleplate is installed on is 3019.50 according to Sheet 26. That puts the elevation of the discharge centerline at 3020.5, leaving no room for an equipment pad. Is the Soleplate actually going to be embedded in the concrete floor as it appears to be called out in Spec Section 33 12 71.C.4?

Refer to updated specification Section 33 12 71, Vertical Turbine Pumping Units, and specification Drawing 33-D-61737.

According to sheet 127, the anchor embedment should be at least 10x the anchor diameter. The Soleplate anchor holes are sized for 10” anchors, and the slab is only 8” thick. Are we to drill a through-hole in the slab and grout in the anchors?

Refer to specifications Drawing 33-D-61667. Contractor to adjust anchorage to work within the dimensional constraints of the slab or provide a proposed anchor design that satisfies the loading conditions.

51 What is the load rating for the spillway bridge? The spillway bridge was designed for HS-20 loading and does not have any load postings. All legal loads are able to use this bridge.

52 Note 9 on Dwg. Sheet 17 states to backfill the Reservoir and River structures with concrete and CLSM.

Please provide a dimension from the ends of each how far this zone is to be.

Specification Drawing 33-D-61666 and 33-D-61676 delineates what is considered the "Reservoir Structure" and the "River Structure", which are 29'-8" long and 22'-6" long, respectively.

May the fish ladder sections founded in rock, other than the Reservoir and River structures, be over excavated and backfilled with compacted backfill to allow for two-sided wall forming? It is unknown how the rock will excavate in regards to overbreak adding unknown risk for concrete over run. The rock excavation payline allows for virtually no overbreak volume for additional concrete.

Two-sided wall forming is not restricted in the contract document; only required in areas above bedrock. If the Contractor prefers to excavate addition amounts to facilitate two-sided wall forming below bedrock, it will be considered at the convenience of the Contractor and the Government will not pay for the additional excavation. Paylines shown in Specification Drawings will be used for payment.

54 The height of the chain link fence (CLIN 36) is not called out. Specification Drawing 40-D-7016 indicates that chain link fences are 6 foot high fabric unless otherwise noted on specific site plans.

55 On Sht. 51, Note 2 specifies the 2” grating. However, the note states the bearing bars are to be 2 ½”.

Please clarify. Refer to updated Specifications Drawing 33-D-61693.
