Drawing E4.3; Spec 25‐ 51‐00, Part 1.2.A

On drawing E4.3, General Note 3. States “The National Park service has provided a sole source justification for telemetry system. The telemetry system and components shall be by Motorola and shall be installed by timberline.

No substitution of specified equipment will be allowed.”

In the specifications section 25‐51‐00, addresses the integrated automation of the project. In part 1.2.A of the section talks about programming and integration of the telemetry system.

Thus the question I have is: Is the integration and programming of the telemetry system part of the sole source services provided by Timberline, or should it be part of the proposal package?

This question and response pertain to the Moose Water System specifications. The integration of the telemetry and control system between the Taggart Tank and Taggart well house should be part of the proposal package. The integration and programing of data reporting from Taggart Well house to Moose Water Lab is part of the sole source service provided by Timber Line.

There appears to be a discrepancy between E4.3, General note 3, and E5.4. Note 1. Please clarify who is to provide specific panels, or if contractor is providing all.

This question and response pertain to the Moose Water System specifications.

Contractor is providing all. The Contractor is responsible for furnishing and installing all equipment, controls, hardware, and wiring at Taggart Well Tank and Taggart Well House.

Is the pre‐proposal site visit mandatory? The purpose of the site visit is to give potential offerors the chance to see the project site for proposal pricing. This site visit is not mandatory.

SF1442 The SF 1442 says the proposal is due 6/2/16 and the solicitation (Page 113) states it is due Monday, June 6, 2016. Please clarify when proposals are due for this project.

Proposals are due 06/06/2016 at 10:00am Mountain Daylight Time (MDT). This typo on the SF1442 has been corrected with this Amendment 001.

Section L, Page 113 Factor 1 – Previous Relevant Experience.

Offeror shall submit 3‐5 examples of past performance on similar projects in scope and costs that occurred within the last 10 years.

Please confirm that a total of 3‐5 examples should be submitted for all three Elements.

Not 3‐5 per Element.

A total of 3‐5 examples.

Projects cited should demonstrate that the Contractor has the technical capability, skills, and experience to successfully manage and perform the three listed elements

Section L, Page 113 Factor 1 – Previous Relevant Experience.

Offeror shall submit 3‐5 examples of past performance on similar projects in scope and costs that occurred within the last 10 years.

Must an example be at a certain percentage complete in order to submit?

It is the contractor's responsibility to submit projects that best demonstrate their capability to successfully complete this job.

Can you post the as‐built drawings for the existing structures that are to be demolished?

As‐built drawings for these structures are incorporated via Amendment 002.

465349‐7, Part2‐2.1.C Please confirm that the influent loadings numbers provided are for one train or for the entire plant. The reason we ask is that the loadings seem unusually high for one train (for a municipal application).

The influent loading provided in 465349‐7, Part 2‐2.1.C are per flow train as specified.

They are higher than the typical municipal application, that is why they are specified in detail. 0002

465349‐ Appendix 3, Part A, Table A1

The flows ADF, MDF shown is different from the flows provided in section 465349‐8 #2.2A.

Please confirm the correct flow to use in the design.

The influent flows and loadings used for design shall be as specified in 4655349. The influent flows listed in Appendix 3, Part A, Table A1 are to be used for the annual life cycle cost analysis. Design is based on maximum loading and flows while life cycle cost is based on average annual loading and flows.

section 465349‐12, 2.5.B.2

This section specifies membrane cassettes to be primarily constructed of 316L SS. Also the hardware is required to be 316L SS. Our typical design is constructed in 304 SS. We have membranes units in 304SS structure installed in mixed liquor in all of our plants without any issues. It generally meets the purpose and is more cost effective. Will 304 SS structure be allowed for this project?

304 SS will not be allowed.

Is there a seismic design requirement? The seismic design requirement is listed on drawing S1.0, Design Criteria, Note 12, Seismic Criteria. Also see Specification 460548 "Vibration and Seismic Controls for Water and Wastewater Equipment".

Do you require a Wyoming Electrical Contractors license for the electrical work?

Yes

We would like to request a two week bid extension. Feedback from subcontractors and suppliers indicate this would enable more favorable pricing for the government on this procurement.

Please refer to Amendment 002, which extends the proposal due date to June 16, 2016 at 3:00pm Mountain Daylight Time.

In Request for Proposal, Volume II – Business and Price Proposal – Small, hubzone small, small disadvantaged, women‐owned, veteran owned small business contracting plan – if the prime contractor is a small business, how do we calculate the “% of total planned subcontracting dollars under this contract will go to subcontractors who are small business concerns.”

Per FAR 19.702 ‐ Statutory Requirements ‐ Subcontracting plans are not required from small business concerns.

To provide best value to the government and meet subcontracting goals it may be necessary to use subcontractors that are not based in the immediate area of the project site. Will the government provide any housing to the contractor or provide RV space for contractor personnel to utilize for housing?

The contractor and their employees and subcontractors shall provide their own housing. From year to year, there may be some RV sites being open and available for contractor use. These sites cannot be counted on for availability and should not be assumed available.

Would the NPS please consider offering a two to three week bid extension to the proposal due date for the Moose Waste Water / Water Plant project? A significant amount of the development of the construction approach, pricing, and identification of interested subcontractors and suppliers takes place following a project site visit. With the site visit just occurring earlier this week, it will take longer than the remaining approximately 2 week time period to complete the project pricing as well as the other qualifications and proposal requirements required for this project. It was brought up at the site visit, but a due date later in the week allows more opportunities for contractors to submit proposal via courier service than offered by a Monday due date. A two to three week bid extension would be most helpful and appreciative to this RFP.

Please refer to Amendment 002, which extends the proposal due date to June 16, 2016 at 3:00pm Mountain Daylight Time.

Looking at this project and see there is one overhead door D6 but I do not see any specifications for it. Is it a coiling door or sectional door?

This response pertains to Moose Wastewater System Improvements. See Remarks for Door No 08, Type D6 and specification section 083323 Overhead Coiling Doors.

I am reaching out to you in writing to find out if there is any rock excavation, drilling & shoot on this project.

Blasting is not allowed.

Amendment 3 will contain additional information/clarification in regards to rock excavation.

Another question that I wanted to ask, pertains to the “Sump Pumps” section in the Wastewater Specs, 43 21 39‐4. Part D, i.‐j calls out for 2” solids handling 2” NPT pumps, then in Part E. calls out for 3” solids capabilities. We would just like clarification as to which size solids this pump needs to pass.

The sump pumps specified in 43 21 39‐4, 2.1.D.4. is correct the pumps should be capable of handling 2" solids. Paragraph E is the general requirement for all submersible pumps requiring the ability to pump 3" solids, the specific pump specification paragraph D, because of the 2" discharge connection, would supersede the general specification.

On the WWTP, what are the required coatings for the Ductile Iron Spools. Spec section 40 05

13.53 refer to sections 09 96 00 and 09 90 00.

Specs section 09 96 00 does not seem to cover DIP and section 09 90 00 is not included in the WWTP specs?

Spec Section 40 05 13.53‐3.2.2 requires finishes applied as specified in Section 09 96 00.

Section 09 96 00‐6 B specifies finishes for "Steel Substrate" which is a common term used for ferrous material including ductile iron.

On the WWTP, on the 3” DI pipe called out as Diffuser Clean/WAS piping shown on P‐7, call out #53 is for a 3” plug “control” valve but directly above that is a notation “FCV‐320” which is for a 4” motorized butterfly valve.

Which is correct ?

The correct reference is call #53, which is FCV‐420, a 3" plug valve with electric actuator. Specification 40 05 23.21‐3 provides the Plug Valve Schedule: FCV‐420 serving MBR 320 WAS, 3", elec. Actuated.

Same for FCV‐410 serving MBR 310.

Is there a Pipe Schedule on this project ? Piping and Equipment

Schedules are shown on the process (P‐) drawings.

On plan sheet P13 there are some butterfly valves connecting to MBR‐310 and MBR‐320 designated as HV‐316, HV‐317 and HV‐326, HV‐

327. They are shown connecting to 4” fittings but called out in the valve schedule as 3”.

HV‐316, HV‐317, HV‐326, and HV‐327 should be 4 inch. The valve schedule 40 05 23.18‐3 should be changed to show 4".

The spec on manual butterfly valves for air service, can these be wafer or lug wafer valves ? It might be a significant cost savings and time saving for the installer.

Per specification 40 05 23.18‐2 the butterfy valves are lugged (wafer style) conforming to

AWWA C504.

I am looking for the “instrumentation and control for process system” specifications that would give me process connections, (flow meters & Ultrasonic Level products), measuring spans (pressure transmitter) etc. to quote the product as stated by the engineering firm. The specs are in section 17000, but they do not give me this information. Are there any “drawings” that would give this info? I found a couple, but it only gives the tag number not the details. They are in the “G” section of the “plans”.

Please refer to the Specifications included with the Solicitation.

It was just brought to my attention that the only wage rates included is Heavy. It would be helpful if you could also include the Wage Determination for Buildings.

The Wage Rates for General Decision Number WY160017 02/26/2016 WY17 have been included with Amendment 0003. 0003

The design criteria specified in G2 sheet of the construction drawings is different from the design criteria in RFP section 465349‐7, Part‐

2.1 and 465349‐8, Part‐2.2. Which influent/effluent criteria should the MBR design comply to?

The MBR equipment should be sized per the design criteria provided in section 465349 in the specifications.
