Questions and Answers

There is growing concern about formulating a 2024 fall work schedule and compliance with the 90 days required for the Government to consider the proposal prior to award. Will there be an adjustment to the reviw time by the Government to allow the contractor to develop a realistic schedule that allows work to initiate in the 2024 season? The solicitation states that any proposal not allowing this time for review will be rejected.

The 90 days denoted in the solicitation is the time period denoted that the contractor's must maintain the pricing not the time period in which the Government will complete its evaluations of the proposals. As stated during the site visit held, all Offerors shall base their construction schedule on a NTP issuance of September 15, 2024. 3 7/18/2024

Will the asphalt contractors need access to PA-01 for the Fall of 2024 season?

See Summary of Work 01 11 -- Section 1.3.A.4 and the FHWA documents. FHWA will require access to RTE 3 for the entirety of the project for various efforts and the Park will require a full lane of access required for their emergency and other work efforts. 3 7/18/2024

Questions and Answers

What is the asphalt contractor sequencing for the PA- 02 work and related timelines? Will there be an opportunity to coordinate sequencing with the asphalt contract prior to submission of this proposal?

See Summary of Work 01 11 00 Section 1.3.A.5. The FHWA work is currently being solicited under Solicitation #69056724B000012 by the Department of Transportation. There will be no opportunity for potential Offerors to coordinate with FHWA's contractor prior to proposals being due. 3 7/18/2024

During the pre-bid it was mentioned that shutting down the water system early might be an option to facility the early work required this fall. If so, what would that date be? How many days are required to drain th existing water system?

The water system is drained every year in September by the Park. 3 7/18/2024

Questions and Answers

What is the difference between CLIN PA 01 and PA 02. It appears to me that all of the water main installation would be complete under PA02. The way the project would have to be constructed would eliminate CLIN PA

01. Please let me know if I am missing something or DJ&A and clarify exactly the areas in PA 01 and PA 02.

PA01 is just the distribution work located within RTE 3 (including the culverts and parking area) that is designated as FHWA project limits . Coordination required with FHWA since this is majority of their project.

PA01 is everything NOT overlapping with FHWA work - FHWA will just come in after for paving.

01 11 00 Summary of Work outlines project area limits and shoudl match how the areas are designated in the drawings. Phase/schedule requirements for PA01 and 02 are laid out in Section 1.3 of 01 11 00 which is also why they are broken up into separate CLINs.

3 7/18/2024

The specs show medium voltage generator and a 208/120 3 phase generator in the drawings. Would you please clarify which is correct?

The generator is 208VAC as per drawings.

4 7/26/2024

Would please provide the well log for the existing well? Attached.

4 7/26/2024

Questions and Answers

Does a certified arborist approved by Glacier National Park need to perform the tree removal?

No - only coordination with Natural Resources Staff relative to the exact number of threes that will need to be cut.

4 7/26/2024

Is the work within Rte 3 CLIN 1 only the 10" HDPE section from Sta. 51+35.56 to 52+84.34 3" HDPE pipe section between Sta. 220+06.01-229+69.27?

See amendment to the specification Section 01 11 00 for revised pipe stations that are within the RT 3 CLIN 1.

4 7/26/2024

Would NPS states the limits of RTE 3 several times in the spec for CLIN 1 PA 01 so we can accurately include the correct costs for CLIN 1?

See amendment to specification Section 01 11 00 for revised pipe stations that are within the Rte 3 CLIN 1 4 7/26/2024

Questions and Answers

See amendment to specification Section 01 35 05 and list of sources from the park.

4 7/26/2024 Attached Approved Gravel and Topsoil Sources

Section 01 35 05-4 F states the following: “All imported borrow, road base, aggregate, crushed fines, bedding, topsoil, hay bales and other fill materials brought into Glacier National Park and used in this project shall be certified noxious weed and noxious weed seed free, and come from approved sources that have been previously inspected by the Park. Certified imported materials will come from commercial sources that have been approved by the CO, prior to materials entering the Park.

1) As of Spring 2019, six material sources on the west side of Glacier National Park were certified weed free for sand and gravel and none for topsoil (see physical data in FAR 52.236-4 for a summary of the materials sources research.)

2) If these sources are utilized, these sources are subject to continual inspections and approval for use each year.

3) All material sources and materials incorporated into the work, except Asphalt concrete aggregate (Subsection703.07) and those listed under Subsection 105.02@(8) must be free from noxious weeks, invasive plants and deleterious materials .

I can't find Subsection 703.07, Section 105.02 or FAR Clause 52.236-4 (Physical data). Would you please provide the information needed to determine the best source available to provide material for the project?

Questions and Answers

Plan Sheets C2.1&2.2 note 3.1 states "The parallel 10" and 4" mains are horizontally separated 3 ft from center of eachpipe. Would a greater separation between the two pipes be acceptable?

A separation larger than 3' between the parallel 10' and 4' water lines may require a larger trenching area, and therefore, a potentially greater disturbance area for trenching and filling; as a result, maintaining pipes as close to 3' separation as possible is preferred. However, alternative pipe separations may be considered if proposed by the Contractor, provided construction disturbance stays within the limits of the existing roadway.

4 7/26/2024

In the specs for temporary water it calls for the potable water pump to be capable of 80 gpm. This does not give us enough information of the anticipated demand on how much water usage that is anticipated so we can accurately estimate the effort that will be needed to supply enough water to NPS staff. What is the anticipated water demand needed on a daily basis for the project?

The temporary water system is sized to the daily anticipated demand for the maximum number of resident staff.

3,000 gallons per system, there are two systems so 6,000 gallons total. She sheet C6.1 detail 1, and specification 01 50 05, 2.4 B.1

4 7/26/2024

Would DR HDPE pipe be acceptable for the 4" fill and 10" distribution from the tank to the intersection of the loop road approximately 850 lf for both?

DR-9 is acceptable as long as it doesn't incur any extra cost to the NPS.

Questions and Answers

On plan sheet X1.2 Note 2 it s tates “Contractor shall coordinate with utility company to refeed chlorination building per electrical one-line diagram. Would you please clarify who is responsible to pay for these fees?

It is very difficult to get prices out of utility companies before bids are due FYI.

The contractor is responsible for payment of any fees associated with this scope of work. 4 7/26/2024

The tank coating Spec 07 16 16 indicates that application of coatings need to be under the supervision of an inspector.

The next spec then indicates that at theoption of the owner, the owner may hire a full time coating inspector. This is a little confusing can you confirm if the contractor is required to have their own inspector or will one be owner provided?

For the water storage tank coating, the contractor is required to provide an inspector. The owner reserves the right to contract their own coating inspector, independent of the contractor provided inspector.

4 7/26/2024

Building 484 on Sheet C2.31 doesn't contain a call out. Can you confirm the size and length.

Service to building 484 is 78 lf of 2" HDPE water service line.

4 7/26/2024

Building 1356 contains 2 service connections. Can you confirm this is correct?

Correct. One for domestic water and one for fire suppression system. 4 7/26/2024

Can you confirm if the Temporary Fire Protection Tanks need to be 10,000 gallons each (20k total) or if the combined capacity is to be 10,000 gallons.

See specification section 01 60 06, 2.4.B.1

4 7/26/2024

Would an alternative to Crystalline Cementitious Waterproofing be acceptable. Obic 1100 Aromatic Polyurea Coating was offered by one installer.

The product suggested will be evaluated according to the relevant specification and if it meets the requirements, it is acceptable.

Questions and Answers

The details of the water meter vaults reference 6, 8", 10" connections. I found 2 - 8" meters and 2 - 10" meters but do not see a 6" meter. Is there a 6" meter for the project and if so where is it located?

There are no 6" meters in the project

4 7/26/2024 68 Are the well pumps on VFD's? No 5 7/30/2024

Based on the Answer to #59 regarding temporary water.

Is the NPS anticipating that both tanks will need to be filled daily?

It is up to the contractor to determine the amount and frequency of tank filling operations based on the size of tanks the contractor anticipates utilizing during the performance of the work.

5 7/30/2024

The specs indicate that the HDPE on this project can be IPS or DIPS. I just want to confirm that IPS is acceptable to make sure my costs are covered.

Yes, both IPS and DIPS are acceptable. See Spec Section 33 31 23 Fusible HDPE.

5 7/30/2024

Are there any domestic material requirements on this project? If so, which would apply (BABA, Buy American Act, etc)?

The Buy American Act is applicable to this procurement. Please see solicitation clause 52.225-11 Buy American - Construction Materials Under Trade Agreements (NOV 2023)

5 7/30/2024

Can you clarify if the Obic 1100PW material alternative is acceptable for the tank lining?

Please see Q66 - The product will be evaluated based on the salient features of specification 07 16 16.

Generally we do not do shop drawing review for anything before the contractor is under contract.
