1240LT25R0012 Reconstruction of Pine Valley Dam, Utah (GAOA)

The following are offerors’ questions and the Government’s responses to these questions:

Q1: Would we be able to get access to the borrow site to pothole it and verify the type 2 fill?

A1: Proceed as outlined—conduct material testing post-award, as required, and verify consistency with our drill logs. If discrepancies arise, we can address them through the appropriate contractual remedies at that point.

Q2: Can the seed be applied by a hydroseeding machine or does it need to be drill-seeded or broadcasted by hand?

A2: Per Construction Specification 6 – Seeding, Sprigging, and Mulching: “Within 24 hours after application of the seed mix, mulch mixed with a tackifier and water shall be uniformly applied to the seeded area using hydroseeding methods. The mulch shall be applied at a rate of 2,000 lbs mixed with 5,000 gallons of water per acre. The mulch used shall be listed on the most recent UDOT Approved List of Wood Fiber Mulches.” Based on this, hydroseeding is an approved method for applying the seed mix.

Q3: How many trees do you anticipate that we will need to take out and approximate size?

A3: The toe berm and low-level outlet work will take place in areas with either no trees or only small trees. The outlet channel will run through a more heavily forested section. Without the formal survey that will be conducted by the survey after award to define the exact alignment, our rough estimate is that up to 10 large-diameter trees may need to be removed. That number could be significantly lower once the alignment is laid out on the ground.

Q4: Can the Autocad files be shared?

A4: The contractor who completed this project’s design for the Forest Service will provide sufficient survey data to the awardee construction contractor’s surveyor to fully lay out the project. However, the actual AutoCAD files will not be shared unless the design engineer chooses to release them during post-award discussions regarding surveying. But, right now, the answer is ‘no.’

Q5: Specification 23, CLINS 8, 9, 17, 18. Please confirm there is sufficient fill materials that meet the specifications, available from the required excavations and borrow sites to fulfill the entire embankment operations.

A5: Based on pre-award assessments, we are confident that the material at the designated borrow site will meet the required specifications. The gradation is broad, and test results from multiple boreholes indicate the material is suitable. Should the material unexpectedly fall short of specifications or prove insufficient in quantity, we will identify alternative source locations and coordinate with the Contracting Officer to assess any resulting differences in haul costs.

Please prepare your proposal under the assumption that the borrow site will be viable. However, note that some effort may be necessary to further develop the pit, depending on how readily accessible the suitable material is. Additionally, unsuitable material excavated from the lake will be hauled to the borrow site and used to reclaim the pit as development progresses.

Q6: Is the Roadbase for Specification 23, CLIN 9 provided by the government?

A6: No, the road base is not Government-provided.

Q7: Are any materials related to Specification 24 Drainfill provided by the government?

A7: No, the drain fill materials are not provided by the Government.

Q8: Can you provide required gradations for gravel, filter sand, and riprap, and masonry stone?

A8: See the Embankment Gradation Requirements table on Sheet G101 of the Plans Set.

Q9: The Schedule of Items subtotals line items 1 through 13 (assumed “base” scope), then subtotals line items 14 through 32. On the plan sheets, the work for line items 14 through 32 are labeled Additive Alternates. Are these alternates that may be added later or does the entire contract get awarded at the same time? If they are not in the “base” scope, and only the “base” scope is performed, the plan sheets do not provide the final condition for this. We are unable to quantify, scheme, and estimate for the “base” final condition without seeing the design that doesn’t show the Additive Alternate items.

A9: Disregard any mention of “Additive Alternates” in the Plans. All line items in the Schedule of Items and in the Plans are Base line items, and the intent of the Government is to award all Base line items 0001 through 0032 at time of award.

Q10: If there is a base scope line items 1 through 13 and an alternative additive scope line items 14 through 32, is this because the government only has limited funding available? In what conditions will only the base scope be awarded? In what conditions will the alternate additives be awarded?

A10: See A9 above.

Q11: Will line items 14 through 32, if awarded as alternate additives, be awarded in an “all or nothing” manner? When will the alternate additives be awarded?

A11: See A9 above.

Q12: Does the government require two alternate schedules in the proposal, one to complete line items 1 through 13, and one to include all line items?

A12: See A9 above.

Q13: Is the 390 calendar days the duration set aside for the base items 1 through 13, or for all line items?

A13: 390 calendar days is the total contract duration for all line items (0001 through 0032).

Q14: Specification 52.225-9 Buy American. Based on recent, relevant, and similar projects, we have been quoted multiple times domestically produced cast iron items, similar to that in line item 32, that are more than double the price than foreign sources and double the lead times due to a massive influx of recent domestic casting issues (tariff pressure, etc.). Some lead times are up to 50 weeks after the design and submittal is approved which will make the schedule very difficult to achieve. In accordance with FAR 52.225-9(c) we respectfully re quest a determination of inapplicability of the Buy American statute for the construction material in line item 32 based in unreasonable cost, nonavailability, and it would be impracticable or inconsistent with public interest.

A14: Pursuant to FAR 52.225-9(b)(2) and (b)(3)(i), the preference for domestic construction material is not applicable to Line Item 0032. However, the COR will still need to approve the material and/or component(s) for Line Item 0032 during the Submittal process.

Q15: Please provide all permits the government is responsible for prior to submission date. If not available right now, what is the timeline for approvals? The specifications are unclear on work windows, in-water work windows, any nesting seasons, or any environmental restrictions.

A15: The Government intends to pursue a stream alteration permit; however, this process cannot commence until after the contract is awarded, as critical inputs—such as the contractor’s dewatering and sediment control plans—are required for the application. As a result, construction is expected to begin in Spring 2026, with a tentative start date shortly after snowmelt, likely around May 1. Although the awardee contractor may request to initiate work earlier on tasks unrelated to the stream alteration, prevailing weather conditions—particularly snow and freezing temperatures from November through April—may limit feasibility. At present, there are no other known environmental restrictions affecting the work window. While unlikely, there remains a small possibility that the stream alteration permit could impact the timing of available work.

The Government is actively coordinating with the state Dam Safety Engineers and has already secured approval for the project.

Q16: Are there any permits, besides SWPPP and UPDES, that the contractors are responsible for?

A16: No. But the contractor is solely responsible for submitting their portion of the stream alteration permit inputs promptly, to help prevent any delays to the project schedule.

Q17: It appears the available data on water flows and reservoir levels is for the new design. Are there any historic reservoir levels? For the current condition, how many cfm should contractors design their water diversion or dewatering systems for?

A17: There is a stream gauge downstream of the reservoir with historical flow data available at this site:

https://waterdata.usgs.gov/monitoring-location/USGS-09408400/#dataTypeId=continuous-00065- 0&period=P7D

Q18: Plan sheet F101, note 1. How much sediment is expected in the upstream excavation area? Which contract line item is this work associated with? What are the sediment limits, i.e. elevation is the bottom of the sediment? If no line item is associated with this work, can a unit priced line item be established?

A18: See Sheet F201 for existing sediment grade lines. Unclassified excavation is captured in Line Item 0007 – Unclassified Excavation.

Q19: Plan sheet F101, note 1. The sediment is expected to be very sloppy. Are contractors allowed to place the sediment in the borrow areas? If not, what is the expected destination for the sediment removed?

A19: Yes, the sediment will be hauled back to the borrow area and used to restore the pit as much as practicable, given the discrepancy between the borrow and sediment quantities.

Q20: Plan Sheet F101, note 5. Where do contractors stockpile the riprap? Where does it get re-used?

What line item is the riprap excavation and offhaul associated with? What line item is the riprap re-use associated with? Does the government have a riprap quantity or is it the contractor’s risk at lump sum work? If no line item is associated with this work, can a unit priced line item be established?

A20: Where appropriately sized, some of the riprap may be reused as part of Line Item 0031 – Masonry Outlet Channel. Any excess riprap will be hauled back to the borrow site. That work will be associated with Line Item 0007 – Unclassified Excavation.

Q21: What elevation(s) are the bottom of the piezometers supposed to be? Sheet E302 note 3 references tip elevations but they are not shown. Also, if the tip elevation is +/- 10’, how will this be addressed since it is a Lump Sum CLIN.

A21: In accordance with the note on Sheet E101, it is anticipated that the existing Piezometers 1 - 3 will be protected in place. Piezometer details were provided on the attached Sheet E302 since the contractor can choose to raise or replace Piezometer 4. The tip elevation of Piezometer 4 is approximately 6681 feet. The note that tip elevations may be adjusted by the engineer is not applicable to this project, and has been removed from the attached revised sheet. The detail for double piezometers is also not applicable and has been removed.

Q22: If the outlet channel work is awarded, what line item does the 4” to 6” thick masonry rock work get included in?

A22: Line Item 0031 – Masonry, Outlet Channel

Q23: What elevation was the reservoir when the borings on Sheet B101 and B102 were performed?

A23: The Pine Valley Dam’s only outlet is its spillway, which is relatively wide. As a result, the flow across it remains shallow throughout the year. Unlike irrigation-related reservoirs, this setup leads to minimal fluctuation in reservoir elevation—the pool stays fairly stable year-round. Therefore, it is reasonable to assume that the elevation at the time the borings were conducted, was likely within one foot of the current elevation.

Q24: Will there be any stripping, stockpiling and reusing of any topsoil? I see stripping of 6” and wasting but no mention of using it as topsoil. Can you clarify please?

A24: The majority of the earthwork will occur in areas where we don’t want topsoil to promote vegetation—such as the lake bottom, the dam, and the gravel pit. As a result, we generally don’t plan to reuse the stripped topsoil.

However, the specifications do give the Government discretion to direct the contractor to reuse some of the material, particularly on the downstream berm. If it makes sense for both parties when the time comes, the Government may be open to working with the contractor to explore that option. Reusing the material could avoid the effort of having to haul it offsite and provide a suitable soil for grass growth to help prevent erosion.

To summarize: we will typically waste the 6 inches of topsoil due to its high organic content, but there may be select areas where reuse is beneficial.

Q25: On sheet F101 note 1 and 2, there is mention of removing sediment upstream of excavation area and provide 12 inch thick lumber crane mats to access the proposed drill holes using a 34,000 lb drill rig, and waiting 2 weeks before contractors can access the site. There is no mention of this item in the specifications or a line item on the Schedule of Items. What line item does this belong to, and can you provide the scope in the specifications?

A25: We are unable to determine the required exaction limits without boring holes and testing the material. However, drilling cannot begin until the lake is dry and a stable mat is in place. Draining the lake depends on when the contract is awarded and the contractor completing the necessary preparatory work.

The drilling will be funded through a separate Inspection and Testing contract. In contrast, the crane mats will be constructed by the construction contractor and are considered incidental to Line Item 0007

– Unclassified Excavation. The cost of building the mats should represent only a small fraction of the value of that Line Item.

As outlined in the Measurement and Payment section of Construction Specification 21 – Excavation:

“Payment for each type and class of excavation is made at the contract unit price for that type and class of excavation. Such payment will constitute full compensation for all labor, materials, equipment, and all other items necessary and incidental to the performance of the work.” In this case, the crane mats are “necessary and incidental” to the excavation work. Since the contractor excavates without testing, and the Inspection and Testing contract is a separate service agreement, it cannot be used to construct the mats.

Q26: Where is the intended access for equipment to enter the upstream part of the reservoir?

A26: The Government will arrange an on-site meeting with the awardee contractor to jointly identify the most suitable access route to the upstream work area, located just above the dam near the fishing platform. Due to the expected volume of haul truck traffic, some route improvements—such as cut and fill operations and potentially limited tree removal—may be required to ensure adequate access.

Q27: Can all embankment material be mined from designated borrow areas or will import be needed from a pit to the project?

A27: Earthfill Zone II material will be sourced from the designated borrow area. In the unlikely event that this site proves unsuitable, the contractor will be expected to work collaboratively with the Government to identify an alternative location, with pricing possibly subject to renegotiation and modification. Site samples have been collected at the designated borrow area and confirm compliance with the required gradation specifications.

Q28: Can spoils from the project be disposed of in the designated borrow area?

A28: Unsuitable soil and topsoil can be disposed of in the designated borrow area.

Q29: Will material that is removed from the reservoir be suitable to be used for embankment material?

A29: The sediment deposits are highly unlikely to meet the specifications for embankment material.

Once the sediment is removed, drilling will be conducted to assess the necessary excavation limits.

Q30: Are there any special requirements/restrictions pertaining to draining the reservoir?

A30: The stream alteration permit—partially informed by the contractor’s dewatering plan—may include specific requirements or restrictions related to draining the reservoir.

Q31: For access on the upstream side are we able to remove some of the trees blocking the way in?

A31: The Government will meet on-site with the awardee contractor to work together on identifying the best access path to the upstream area.

Q32: Is there access to water close to the borrow pit? Ie: Hydrants.

A32: No; the closest hydrant is at the entrance station. There is a hydrant at the parking lot adjacent to the dam.

Q33: For the dewatering, are you able to provide the requested dewatering engineered plan?

A33: The awardee contractor is free to work with any licensed engineering firm for the dewatering plan.

RB&G has provided this service in the past and may be an option again.

Q34: How much volume of water can we release down the creek?

A34: The Government will coordinate with the awardee contractor to initiate the stream alteration permit process. The Government will handle the submission and cover the associated fee. All permit conditions will be followed; however, there are no specific restrictions on the volume of water to be released. While we won’t be discharging twelve times the typical flow, there is flexibility to significantly increase it, as needed.

Q35: Is there a weight limit for the road from the borrow to the reservoir? Meaning, can we run rock trucks up and down?

A35: Only highway-legal vehicles and loads will be permitted for hauling.

Q36: Do you have a list of planholders for this project?

A36: We currently have 3 separate lists of attendees at Site Visits held on 22 November 2024, 05 June 2025 and 19 August 2025. Please note that attending a site visit is not a requirement to submit a proposal. Attendance Sheets for those 3 Site Visits are attached herein.

Q37: We do not see a disposal area in the drawings, can you clarify where we are supposed to dispose of these materials (clearing/grubbings, excess topsoil, unsuitable materials, etc.)?

A37: Cleared vegetation, excess topsoil, and unsuitable soils may be disposed of at the designated borrow site.

Q38: Is there a stockpile location for suitable materials to be reused in the dam construction?

A38: The Government will coordinate with the contractor to identify an appropriate stockpile location at the dam for reusable materials. The selected area will be chosen to avoid interference with construction activities and to minimize additional site disturbance.

Q39: The last two sheets of the plans show borings; is there a geotechnical for these borings? If so, could we get this report?

A39: Additional soil information consists of internal documents developed to support the final design of this project. These materials are not intended for public distribution and will not be included as part of the solicitation.

Q40: For piezometers shown on page 13 (E302), what are the depths needed?

A40: In accordance with the note on Sheet E101, it is anticipated that the existing Piezometers 1 - 3 will be protected in place. Piezometer details were provided on Sheet E302 since the contractor can choose to raise or replace Piezometer 4. The tip elevation of Piezometer 4 is approximately 6681 feet. The note that tip elevations may be adjusted by the engineer is not applicable to this project, and has been removed from the attached revised sheet. The detail for double piezometers is also not applicable, and has been removed

Q41: Can Haul Trucks and/or Scrapers run on FH 035, the road to the borrow site? This is a paved road from the project site to a required government provided borrow source. It is highly likely the paved road will be damaged to complete the work and contractors are to fix what is damaged. What CLIN are repairs to this road to be covered under? If it is incidental, can the government add a CLIN to cover this cost so all bidders include these costs on their bids?

A41: Only vehicles that are legally permitted on highways may use the paved campground road between the pit and the dam. Contractors are responsible for any damage caused to the road edges when entering or exiting the paved surface, as they have the ability to implement protective measures.

However, as long as haul vehicles maintain loads within the legal highway weight limits, the contractor will not be held liable for any damage to the asphalt along the designated haul route.

Q42: Is the park and the construction areas open to the public during the construction durations? If so, what are the flagging requirements? What CLIN are those efforts to be carried in?

A42: During the construction period, public access to the dam and the adjacent parking lot will be restricted. The road connecting the borrow pit to the dam will be temporarily closed on workdays (e.g., Monday through Thursday) using road closure signage, and will reopen on weekends to facilitate traffic flow. The installation and removal of these signs each week is considered incidental to Line Item No.

0008 Earthfill, Zone II, and will not be treated as a separate pay item.

Q43: In the Specifications, Section 2 Clearing and Grubbing, on Pages 2-3 Item 7, it states “Unless otherwise directed by the Engineer, approximately 6 inches of soil shall be stripped and wasted from the footprint of the required excavations and embankments”. On Plan sheet F101, Note 7 states “strip 6” of soil within the footpring of all fill materials. Use striped material as Topsoil”. Please verify the correct direction, if the stripped topsoil materials are to be wasted or reused? If it is to be reused, please define the processing required for re-use and CLIN this effort is to be included in?

A43: The majority of the earthwork will occur in areas where we do not want topsoil to promote vegetation—such as the lake bottom, the dam, and the gravel pit. As a result, we generally do not plan to reuse the stripped topsoil. However, the specifications do give the Government discretion to direct the contractor to reuse some of the material, particularly on the downstream berm. If it makes sense for both parties, we would be open to working with the contractor to explore that option. Reusing the material could save the contractor the effort of having to haul it offsite and provide a suitable soil for grass growth to help prevent erosion.

Q44: If the topsoil is to be wasted, can the contractor place it onsite? If so where is this allowable?

A44: See the answer to Question 43 above. If we cannot find a suitable location to reuse topsoil, it would be wasted at the borrow site.

Q45: Can you extend the bid date two weeks?

A45: No. Due to the structure of Forest Service budgets, it is critical that we make an award by end of September 2025. If we miss this window, funding may not be re-authorized until Spring 2026, delaying the award process significantly. By that time, existing proposed pricing will likely have expired, requiring a restart of the solicitation process entirely.

Proposal due date is extended to 1700 CDT on Tuesday, 09 September 2025.

Q46: Can the government provide details for the articulating concrete blocks revetment system? Details are missing like typical block size, thickness of revetment, connector details for mats etc.? Are there any recommended manufacturers pre-approved by the government for use?

A46: From Construction Specification 65 -- Articulating Concrete Block Revetment System: Unless otherwise approved by the COR, each open cell block shall have a gross area of at least 1.7 ft2, shall weigh at least 55 lbs, and shall not have more than 20% open area. We do not know of any pre-approved manufacturer or vendor; however, you can start your market research for sources and information with the following supplier whom some contractors have used:
