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. 0001

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. 0001

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. 0001

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 0001

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.

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.

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 of the specifications.

Is the 20% small business mandatory participation percentage based on the base bid amounts only to determine the percentage met?

Please refer to Section L ‐ Instructions, Conditions, and Notices to Bidders of the

Solicitation. Subsection C. Proposal Format, Volume II ‐ Business and Price Proposal, 10.

Small Business Participation Plan states, "The

Offeror shall propose the level of participation of SB concerns (as a SB prime and/or no lower than first‐tier SB contractors) that

GUARANTEES A MINIMUM OF 20 PERCENT OF

THE TOTAL CONTRACT VALUE WILL GO TO

SMALL BUSINESS in performance of the acquisition."

On sheet PD1 wall penetrations are shown in detail 9 as using a flanged pipe spool with seep ring and tapped bolt holes on the flanges – however detail 8 shows a cored hole with double links seals which is much less expensive. Can contractors use either one ? what is the rule for using detail 8 versus detail 9

The wall penetration details on PD1 are standard details that the contractor may use for the appropriate application. The contractor may use detail 8 for a straight pipe thru the wall; Contractor may use detail 9 for a penetration that requires a flange connection at the wall (note detail 8 would not work for a flange connection at the wall because the flange would block access to the link seal).

Contractor may use detail 10 for a penetration that requires a flange or mechanical joint connection 6‐inches from the wall, (note detail

8 would not work for a flange or MJ connection

6‐inches from the wall because the flange or

MJ fitting would block access to the link seal).

The majority of the wall penetrations shown on the Wastewater Treatment Plant (WWTP) drawings are laid out to use detail 8.

Penetrations thru the floor or the water tank shall be with wall pipe as shown on detail

1/S2.5 of the Moose Water Drawings.

Penetration thru the wall of the water tank shall be with wall sleeve and link seal as shown on detail 1/S2.4 of the Moose Water Drawings.

In the Ductile iron spec section 40 05

13.53 ‐3 C110 is listed for Fittings, but the industry standard now is C153 (for

MJ fittings) will C153 fittings be allowed?

The contractor may use AWWA C153 for buried service ductile iron mechanical joint fittings where the pipe is cut to length. The layout of the piping in the Wastewater Treatment Plant

(WWTP) and the Taggart Well house is based on AWWA C110 flange fittings, AWWA C153 compact MJ fittings will not work in the WWTP or Taggart Well house.

Section L of

Solicitation

When are the reference evaluations forms required for the technical proposal?

Are they to be submitted directly to you?

How will we know if they have indeed been sent to you?

Past Performance Questionnaires are due no later than the proposal deadline. Any responses received after the deadline will not be evaluated. Questionnaires shall not be submitted with your proposal package. Per the instructions at the bottom of Page 3 of the

Questionnaire (see Volume I Submission

Package), the forms shall be submitted via email to sarah_clemmens@nps.gov and jason_longshore@nps.gov. This email submission shall come directly from the party providing the reference and NOT the Offeror.

An email to the original sender will be sent upon receipt.

This is a request to provide the CAD files for earthwork to include existing & design contours for the concrete tank, well house, and WWTP.

CAD files will not be provided prior to award.

Note, approximate volumes for earthwork at

Taggart Tank are given in the construction drawings for information. Contractor shall be responsible for computation and verification of actual earthwork quantities

IMPROVEMENTS ‐

Drawing subsheet

M4.1

On reviewing the drawings and specifications, I noticed on Sub Sheet

M4.1, Drawing No. 136/114087A Sheet

99 of 161, Titled, Treatment Plant

Mechanical Schedules, that the air filters specified in the Makeup Air Unit

Schedule call out a prefilter of MERV 8 and final filter of MERV 11, for both

MAU‐1 and MAU‐2. The prefilter is called out correctly, but the final filter should be called out as MERV 14 for both MAUs

A MERV 11 final filter is not sufficient to protect the ion tubes that we will be supplying, from excess fouling and premature loss of performance.

Please refer to Attachment 001 of Amendment

0004 which revises drawing subsheet M4.1 for

MOOSE WASTEWATER SYSTEM

IMPROVEMENTS.

Quick question on TV‐320 and TV‐310 telescoping valves, please. I see on drawing P7 the HWL of 101’‐0” on the

MBR‐310 and MBR‐320 but I don’t see a

LWL elevation.

I also didn’t find a length of travel in

Spec Section 40052372 2.4 so I just wanted to clarify the desired travel.

The LWL will depend on the membrane manufacturer and the minimum transmembrane pressure (TMP) required for their membranes to function properly. With the membrane shown on the drawings the lowest probable LWL would be elevation 98.5'.

In regards to the length of travel, we suggest planning on ordering the maximum travel available given the telecoping valve's seal requirement.

Please provide spec section 07 53 16 ‐

CSPE Roofing

Section 07 53 16 will be provided in amendment 005 and shall be incorporated into the specs titled "ADDRESS CRITICAL MOOSE

WATER SYSTEM DEFICIENCIES"

Can the contractor stock pile excavated material in areas other than the

“designated stock pile area transfer site” that are within the limits of disturbance

Materials from the excavation for the new water storage tank may only be stockpiled in designated locations, as stated on the construction drawings ‐ this shall include temporary stockpiles. Concern is for risk of excavated materials being contaminated with weed seeds from any locations other than those designated (large areas adjacent to the stockpile transfer location exist with known weed infestations).

Spec ‐ 31 23 17, 3.5.A.3, What intervals will be required to re‐excavate waterline for bedding compaction inspection?

The interval of inspection will be determined by the CO and/or COR based on contractor performance.

Can the mow operations within the water pipeline alignment be done the day after Labor Day or do we have to wait until the first day of Autumn

(9/22/16)

Proposed Response: Part 1.3.A.3 of section 01

11 00 states "When practical, complete mowing and mulching of waterline construction corridors. Work shall be completed the fall prior to construction to prevent birds from nesting within the construction corridor the following spring."

Mowing operations shall be limited by initial year construction date after Labor Day 2016.

However, mowing operations in a normal year may proceed after June 30th, provided a bird survey has been done prior to mowing and prior to August 1st. After August 1st, mowing may take place until winter shutdown, and subject to startup dates in Spring.

What are the limits or boundary of the

“Park”, specs mention limitations to the contractor within the “Park”. What is considered inside or outside of the

“Park"

The park boundary is shown on sheet 1 of both set of drawings (Drawing No. 136/114087A &

136/114086A). The term "Park" shall be reserved in most context to mean Grand Teton

National Park and John D. Rockefeller Jr.

Memorial Parkway ‐ legal boundaries.

Spec – 01 50 00, where can we store fuel trucks outside of the park?

Contractor shall be responsible for coordinating and obtaining approvals for storage of fuel trucks. 0005

Are there any limitations to staging equipment or materials within the Limits of Disturbance for the water pipeline work?

Refer to drawings and specifications.

Contractor shall not stage or drive outside the limits of disturbance. Note the drawings show designated staging areas.

Where are we allowed to discharge flush water from the water pipeline?

Refer to specification section 33 13 00

(Disinfection of Water Utilities)

Will the NPS consider pushing the bid back until June 23, 2016 3:00 pm? This will give the contractor the necessary time to review and incorporate your final addendum from the final questions deadline. Depending on when the final addendum is issued, the contractor may have less than 4 days to review your final addendum.

Please refer to Amendment 005, which extends the proposal due date to June 22, 2016 at

3:00pm Mountain Daylight Time.

This is a request to extend the bid date to June 23rd 3pm. We need more time to evaluate ALL of the documents and to incorporate the final Addendum for this project.
