About this file
This document is a Questions and Answers (Q&A) amendment for the LAKE 254108 Calville Bay Barge Relocation federal contract opportunity, solicitation number 140P2025R0016, issued by the National Park Service. The amendment covers multiple clarifications for a marina barge relocation project, including wave attenuator specifications, site conditions, construction logistics, and key contract details. Significant updates include: the wave attenuator is an option that NPS anticipates awarding, the bid due date has been extended to June 23, 2025, at 14:00 MT, and a new Notice to Proceed date of September 1, 2025, has been established.
The project involves relocating a barge at Callville Bay, with complex requirements including wave attenuator installation, utility coordination with NV Energy, site access limitations, and specific environmental considerations. Key technical requirements include wave load calculations, water level design criteria, and specific construction constraints such as limited boat launch access, invasive species decontamination procedures, and staged construction during non-peak marina seasons. The contractor will be responsible for site preparation, barge demolition, new barge installation, utility coordination, and compliance with local environmental regulations, with an estimated NV Energy coordination cost of $200,000 and potential for equitable adjustments based on actual utility work.

| LAKE 254108, 140P2025R0016 Questions | Government Response | |
| 1 | -Specifications, Part 3- Executions |
-C, Contract Line Item No: 3 Wave Attenuator
| Question: During the pre-bid meeting it was noted that Contract Line Item No: 3, Wave Attenuator will be changed from Line Item3 to a "Add Option". Can the National Park Service please confirm. | Amendment 3 updated the specifications to match the solicitation where the wave attentuator is an option. | |
| 2 | -Specifications, 1.5 General Design Criteria, F 1a: States a significant wave height of 1.5ft. |
Question: There is a discrepancy in these specifications compared to SECTION 35 51 13.02 – FLOATING WAVE ATTENUATOR, 1.5, E, Wave loads
a. Significant wave height of 3 feet.
b. Maximum wave height of 4.6 feet.
c. Wave period equal to 3.3 seconds.
| Please clarify. | Section 1.5 E is correct. | |
| 3 | -Specifications, Floating Wave Attenuator, 1.5 General Design Criteria |
G. The design water levels, based on the 1988 North American Vertical Datum (NAVD88) are:
The design water levels, based on the 1988 North American Vertical Datum (NAVD88) are:
1. Extreme High-Water Level: +1,200 feet NAVD88
2. Current Water Elevation: +1,060 feet NAVD88
3. Extreme Low Water Level: +950 feet NAVD88
| Question: What is the anticipated water level at time of wave attenuator installation? | Given that the construction sequencing and schedule is the contractor's responsibility, an exact water level can not be given due to the seasonally changing lake levels. A range of anticipated values is available from the Bureau of Reclamation who releases a 2-Year Probablistic Projection of the Lake Mead Water Level. Here is the website for reference: https://www.usbr.gov/lc/region/g4000/riverops/crmms-2year-projections.html. Please refer to this website for the range of anticipated values. | |
| 4 | 1. Wave Loads (WavL) shall be calculated based on the following minimum values, maximum |
possible wave caused by the highest significant wave, or the maximum wind wave generated, whichever is greater. Use local values if such values exceed the minimums provided.
a. Significant wave height of 3 feet.
b. Maximum wave height of 4.6 feet.
c. Wave period equal to 3.3 seconds.
LAKE 254108
072624 035 51 13.02 - 7
FLOATING WAVE ATTENUATOR
d. Wavelength equal to 36 feet.
| e. Fetch equal to 3 miles. Question: Can the contractor/wave attenuator manufacture rely on the design data given in the bid documents or is it the intention for the prime contractor/wave attenuator manufacture to engage with a coastal engineering firm to provide their own wind wave study? Any such study would add thousands of dollars to the project, cannot be performed prior to the bid, and would duplicate the work already performed by the Owner’s engineer. Please confirm the bidders can rely on the design criteria provided to establish their cost proposal and no further studies are required on establishing the design criteria. If the Owner requires the bidder to provide a duplicate study, how does the contractor change their design/cost if the wind wave study shows the design values of the bid are greater than the bid documents? | A wind and wave study has been performed and used to determine the design criteria provided in the bid documents. The contractor shall use the values specified in the bid documents. | ||
| 5 | Question: During the pre-bid walk through it was noted that there is existing water intake pipe on land that has been abandoned in place. Is the contractor to remove/dispose of the abandoned pipe not shown on the plans? If so, can NPS state how long, weight and amount of pipe to be removed and disposed. | For bidding purposes, please assume an additional 500 lf of hdpe pipe (same size and thickness as existing) for the abandoned water line to be disposed of in addition to the existing water line. | |
| 6 | Question: Does the barge material and wave attenuator, if made from steel need to be hot-dipped galvanized? | Yes. | |
| 7 | Question: Will NPS grant a minimum 3- week bid extension to allow bidders enough time to evaluate the answers from NPS and put together a comprehensive bid. RFI's are due May 13. A bid date of May 23 does not give enough time. | Yes. A 3 week extension will be granted. The bid due date has been extended to June 13th, 2025 at 14:00 MT. | |
| 8 | Question: Does the NPS have the bathymetric survey file they can share with bidders? This is important to see distances and depths for anchor layout locations. | Yes there is a bathymetric survey file, which will be shared with bidders in this amendment. The contract drawings have bathymetric survey data and approximate distances to the anchor location with respect to the barge. The contractor shall confirm depths at time of installation. | |
| 9 | Question: Will NPS allow the contractor to cast the concrete anchor blocks onsite? This option will save NPS money on the project by reducing shipping cost on concrete anchors. | Yes. | |
| 10 | Plan Page G2 Site Specific Notes: Has a requirement to First Construct a Road between Stations 76+00 and 89+00. Please confirm the requirement to build a road that will be excavated for placement of Utilities? | The contractor will not be allowed access to the ridge line between the barricades shown on the plans, see Sheet C2 and C3. In order to access the rest of the project site, after Station 76+00, an access road will need to be constructed. The contractor may install the waterline and electrical conduit while constructing the access road from 76+00 to 89+00. If the access road is initially built without the waterline or electrical conduit, the contractor will need to come back to excavate it. | |
| 11 | 24” Boulders are identified on the plans both at the entry way and Equipment Site Plan. Can we get an estimated quantity for these Boulders? Will the “color” approved by the Contracting Officer be based on Local Availability? Can we get an install Detail? | Detail 3/C8 states that the contractor to install boulders on 10 feet of either side of the access road while there are also boulders shown on sheet C6. The boulders do not require stacking and may be laid in a singular line. Vegetation or rocks larger than 2" shall be removed from the ground to ensure that the boulders are placed on a flat, firm surface. Please refer to these sheets to estimate the number of 24" boulders required. The color will be based on local availability and shall match the Loop D Campground surrounding colors. | |
| 12 | Sheet C10 shows a Water Bar Detail, can you identify on C1 Profile Plan, where and how many we’re expected to install? | Water bars are specified for the Cross Slopes with Variable Cut/Fill Access Road detail (1/C11). This access road cross section is specfied from Sta 75+00 to Sta 89+00. Please refer to the roadway slope and the spacing on the water bar detail to estimate the number of water bars that will be required. | |
| 13 | NV Energy – Can we still get substantial completion if we’re waiting on NV Energy to complete their work or documentation? In our experience they can take upwards of a couple of years to closeout on a project. | NVEnergy's work is required to power the new barge water intake system which must be commissioned prior to demolition of the existing system, thus substantial completion would not be given prior to completion of their work, however if the new intake system is commissioned and functional, it would be acceptable to NPS to issue substantial completion even if full documentation from NVEnergy is lagging. |
NVEnergy's initial estimated cost was provided over 6 months ago. NPS has asked for an updated estimate but has not received a response, so please assume their fee will be $200,000 based on their initial estimate for bidding purposes which included costs for construction, removals, inspection & scheduling, design & coordination, easements & permitting, contracts & asset management and their taxes and contigency. NPS acknowledges this will likely change and equitable adjustment would be reasonable with appropriate documentation (NVEnergy invoicing).
The engineer of record, Stanley-DOWL signed the original design initiation agreement and has been coordinating the design since July 2024. The project team is in the process of transferring responsibility to NPS through an "assignment and assumption agreement" so that NPS can sign the design approval agreement as the design has been completed in order to initiate the lands review process. NPS plans to go through a similar process upon award to transfer responsibility for coordination and payment to the contractor.
Yes, as noted on Sheet E3, Key Note 3 "Coordinate and schedule removal of utility transformers with CO and utility."
| Specifications SECTION 01 27 00 – DEFINITION OF CONTRACT LINE ITEMS, 3.1 E.1. states, “NV Energy to provide the estimated costs of these services” | ||
| In our experience, NV Energy gives an estimated cost, but after construction sends a bill that is almost always higher. Will NPS be making an equitable adjustment for these cost increases? Especially since they will be forecasting out? | ||
| Who will be signing the Design Initiation Agreement with NV Energy? Is the Contractor to act as a Proxy in behalf of NPS? | ||
| Has this work already gone through the Design and Estimate Phase with NV Energy for approval? | ||
| We have reached out to NV Energy several times with no response. Does the Parks Department have an Estimate they can share with us? | ||
| Does NV Energy own the existing Transformers, and will we be coordinating their removal with them? | ||
| 14 | SECTION 02 41 00 – DEMOLITION, 3.3 JOB CONDITIONS AND PROTECTION OF PROPERTY | Per the specification, dust control must be implemented at all times to prevent the spread of dust, particularly when winds exceed 10 mph and cause dust to leave the site. While general industry practice often allows for dust control measures to intensify around 10–15 mph and suspension of activities around 25+ mph sustained winds, the Contractor remains responsible for ensuring compliance with NDEP Air Pollution Control regulations and any applicable permit conditions. |
Please refer to the Dust Control Permit issued by the Clark County Department of Air Quality for specific thresholds and required responses, as these may vary depending on the activity, site conditions, and regulatory requirements. Work must be adjusted or stopped as needed to maintain compliance and avoid violations or notices from the regulatory authority.
| Dust Control: Use all means necessary to prevent the spread of dust during performance of the work; thoroughly moisten all surfaces as required to prevent dust being a nuisance to the concurrent performance of other work on the site. Wind in excess of 10 MPH causing dust to leave site will require Contractor to limit dust-causing activities. Note all work must be performed in accordance with the NDEP Air Pollution regulations and associated permit. | ||
| Standard practice is to implement dust control measures to prevent “fugitive dust” when winds are sustained around 10 – 15 mph, and to shut down excavation/dirt work activities when the wind is sustained at 25 mph+ for long periods of time. Please confirm. | ||
| 15 | Design – There is a substantial amount of design required from the Contractor. Example: the Barge, the Wave Attenuator, and the Marine Grounding. Was this project meant to be a Design-Build? | No. Typically manufacturer's of barge and wave attenuators have proprietary designs and design them specifically for site conditions. Leaving the design to the supplier/manufacturer allows for increased competition as it does not limit the contractor to a single source. |
| 16 | 8. 6. SECTION 31 23 00 – EXCAVATION AND FILL, PART 2 – PRODUCTS, 2.1 SOIL MATERIALS, B. Native Material, 1. Selected native soils excavated from the site may be utilized as backfill material for nonstructural embankments, structural fill, and general backfill areas with the approval of the Contracting Officer and meets the requirements under Import Materials. | 1) The Memorandum from DOWL describes that a large portion of the native alluvial materials are suitable for backfill provided they are processed per the stated recommendations. The suitability of the bedrock as a backfill material will be dependent on the contractors means and methods. |
2) Bedrock was encountered during the test pit exploration and is anticipated during trench excavation. Please refer to the NV Energy Standards, the Electrical Notes on Sheet C2-C4, Detail 1/C9, Detail 2/E16 and Sheets C2-C6 to estimate the cut and fill trench quantities.
3) Groundwater and soft or yielding clays were not encountered during the subsurface exploration. Widespread dewatering and fabric is not anticipated throughout the project. However, there is potential for localized areas requiring dewatering and fabric installation.
4) We are willing to accept proposals for longer open trench lengths provided that the contractor can provide a secure and safe site that prevents injury to workers and wildlife.
| Based on the Memorandum from Dowl, this is a soil Type C, can you confirm that testing performed shows that a large portion of the Native Materials are unsuitable and Fill will have to be imported for the Trench backfill and compaction? Please confirm we will be digging through bedrock and expected cut and fill quantities for the Trench. Can you also confirm the need for dewatering the Trench and the requirement of a Woven Fabric? | ||
| G. Open Trench | ||
| 1. Maximum Length: The maximum length of the open trench in the aggregate at any one location is not to exceed 200 feet. The trench is considered open until fill is completed to adjacent finish grade elevation. Testing requirements of the C900 pipe would dictate the trench remain open till the entirety of the pipe can be hydro tested with a visual inspection on all fittings, bell restraints, and thrust blocks. Please advise. Stopping Excavation every 200’ and running conduit or pipe and then backfilling with testing would be highly cost prohibitive. | ||
| 17 | 1.3 Statement of Limitations | 1) The asbestos containing gaskets will need to be abated by a licensed abatement company. A black gasket was found to be negative for asbestos and a blue-grey gasket was found to be asbestos containing. When removing the gaskets the contractor will need to determine if the gasket contains asbestos based off its color and further sampling will not be required. However, if a different gasket is found, then it will need to be tested. |
2) Yes, the contractor will be required to remove the existing contaiminated soil. The amount of contimantion found indicates that it may be able to be disposed of as non-hazardous waste. However, contaminated soil will need to be managed in conformance with federal, state, local and NPS regulations and guidelines. See Appendix C of the Hazardous Waste Assessment for an image of the contaminated area.
3) The removal of waterfowl droppings will be dependent on the contractors means and methods for the barge demolition. The contractor will be responsible for coordinating with the landfill or place of disposal to determine if waterfowl droppings are acceptable.
| Pipe gaskets at connections that are still in service or connected were not sampled. Gaskets should be verified to the two sampled gaskets in the report for determination of homogenous material. Please confirm that we will have to have this tested and that a licensed Abatement Company will have to perform the removal of “hot” materials. | ||
| Based on their other findings and reports, is the Contractor expected to perform soil removal and amending due to the “spill” of diesel fuel at the existing site? | ||
| Is the Contractor expected to perform Hazardous Waterfowl Droppings removal on the existing Barge prior to Demoing and Removing it? | ||
| 18 | The Wave Attenuator is shown as an Option on the Proposal. However, due to the weather and wave size, we would not be able to install a Barge without one, and could not provide a warranty for the equipment in water. Please advise. | Due to fund sources for this project, the wave attenuator was required to be solicited as an option. The risk to the investment is understood by NPS budget and we anticipate award of this option. It is acceptable to note in proposals that warranty of part of installed work (any damage that could be attributed to the lack of a wave attenuator) is contingent upon receipt of the award for the wave attenuator option . |
| 19 | Could we get a 30-day extension to the Bid Due Date? The answers to the above questions will materially change the budget for this Project and our Bid. We would not be able to effectively price these items in the short period of time from when these get answered and we need additional time to review the newly provided Specifications. | The bid due date is extended to June 23th, 2025 at 14:00 MT via Amendment 5. |
| 20 | The solicitation states, “complete and submit the attached “General References,” form. Information will be used in determining Responsibility pursuant to FAR 9.103. | The General Referrences Sheet is added to the solicitaiton as apart of Amendment 4. |
| Q: A form titled “General References” was not provided in the solicitation packet. Will the Government issue the form and/or let the Offeror know what information is required to determine responsibility? | |||
| 21 | Due to the sensitive nature of the area, are we required to have a cultural monitor during construction? | As the sensitive area is being avoided, a cultural resource monitor is not required. Park cultural resources may check in on the project as work advances. Inadvertent discoveries shall be in accordance with 01 35 13.22 3.2.A If contractor discovers archaeological resources or human remains, stop work immediately within 100’ of the discovery and report the discovery to the Contracting Officer. Work may continue outside the 100’ buffer until Cultural Resource staff evaluate the discovery. | |
| 22 | We see the requirement for a full time QC, is the Superintendent able to also cover the role of Site Safety Officer? | The superintendent may not serve in any other key personnel position. | Amendment 5, Posted 5.27.25 |
| 23 | -Question: -Is the wave attenuator manufacture required to have a quality control system as part of their business practice. If so, is Iso 9001 certification specifically for the manufacturing of floating docks/wave attenuator acceptable. Are there other acceptable quality control programs that NPS would accept? | The contract documents do not require a specific quality management system or overarching certification for the wave attenuation manufacturer, however a quality control plan must be submitted per 35 51 13.02 1.4.I: "Submit a quality control plan to be used during the manufacture and installation of the floating wave attenuator." Additional submittals like certified test reports of material 1.4.F and complete and accurate records of manufacture 1.4.K are meant to document adherence to industry standard tests referenced for manufactured materials. The quality control plan should reference other relevant specifications for certification of staff and testing standards for example, welding inspection and testing requirements in 05 12 00. | |
| 24 | -Specifications, Floating Wave Attenuator, 1.5 General Design Criteria - |
H. Design Considerations
1. Wave attenuation shall reduce transmitted wave height to a maximum of 1’-6”.
Question: Based on the specifications, the proposed wave attenuator needs to attenuate a 4.6ft maximum wave (3ft significant), to a 1.6' maximum wave (0.9ft significant) transmitted wave height. Our preliminary estimation for wave attenuation is per the attached chart. Using a 10' wide attenuator a 7' draft is needed to achieve the specified attenuation performance directly behind the attenuator. This attenuation does not include wave energy that can go through the floats (if there are gaps between modules) and refract around the ends of the floating structure. The type of material to construct the attenuator doesn’t matter to achieve this level of attenuation but does require this minimum draft at this specified width with no gaps between any of the segmented modules. We recommend utilizing a concrete match-cast structure constructed in modular segments, then post-tensioned together to act like a single floating beam. This type of structure will be less expensive than a steel structure, while also providing historical proof of performance along with the least maintenance. Is a concrete floating attenuator an acceptable equal with the engineer of record providing structural calculations for such a system? A steel floating structure will be more expensive than a concrete structure, so we recommend this solution as an approved equal.
| Please see below for preliminary calculations. The graph below shows the draft needed to achieve the desired attenuator performance. Match-Cast Concrete Technology is a proven method for wave attenuation in similar environments. The “Chelan” reference is an example of an attenuator, installed and in use. | Alternate proposals are not allowable. Value engineering proposals can be considered after award. | |
| 25 | -SECTION 35 51 13.02 – FLOATING WAVE ATTENUATOR, Part 2 Products, 2.1 Wave Attenuator Materials |
A. Wave Attenuator System may be manufactured from structural steel.
Question: This suggest alternative materials such as Match-Cast Concrete may be considered. Please confirm? Further, the plans on sheet G3 under Wave Attenuator Section, Concrete,1.0 state concrete psi ratings, chamfered edges on concrete, finishes and hardware attached to concrete etc…, this also suggest concrete may be used for the wave attenuator. Please confirm.
| See response to #24. The concrete section on sheet G3 is intended for the concrete blocks anchoring the wave attenuator. | ||
| 26 | -Question: During the site visit it was noted the launch ramp at the marina can be used for loading/offloading. Can NPS tell the contractors what the weight limits are for the launch ramp panels? This is needed in order to calculate the ramps capacity for the offloading crane. Some ramp panels looked in bad shape. In addition there is a dirt area on the side of the launch ramp. Can this area be used for crane offloading if the ramp panels cannot handle the loads? | The design loading for the precast launch ramp panels was a 7500lb wheel load. The design vehicles for the panels was a Type 1 ambulance 25,000lbs GVW (10,000 lbs front axle and 15,000lb rear axle). |
The dirt area on the south side of the ramp can be used for crane off loading if the panels cannot handle the loads but minimum two (2) week coordination is required.
27 Question: Can the boat launch be shut-down for offloading docks? Can NPS clarify an in water staging area for dock assembling? A partial closure of the public boat ramp for construction operations is acceptable between Labor Day (Sept) until Memorial Day (May). The partial closure shall include a minimum access width of at least one 20ft lane for public boating access. The request for the partial closure should be made via written request to the contracting officer at least (2) two weeks prior to the date that the ramp needs to be closed. A plan and schedule for the work should be included in the official written request and the scheduled closure should be a line item in the project baseline schedule for the Park's advanced planning purposes. In water staging off of the boat ramp could be included in this type of closure request. See 01 11 00 1.7.D & E for other restrictions.
Additionally, an alternative water access point to the north of the existing ramp is available as shown on the figure attached for #28. The improvement and maintenance of the highlighted access route and temporary launch area would be the contractor's responsibility similar to the improvement and maintenance of the access route from the campground to the equipment site.
| 28 | Question: During the pre-bid meeting, NPS indicated that they can dedicate laydown area near the marina or parking lot near campground. Can NPS show on a map where this staging is located? | Contractor Use Areas includes abandoned Campground Loop D, a small area near the fire hydrant identified for contractor use at the hydrant near the RV park and the eastern portion of the old boat ramp. See figure attached in amendment. |
| 29 | Question: During the pre-bid meeting it was noted that there is invasive quagga muscles in the lake. Who is responsible for quagga muscle inspection/decontamination if required? Is there a requirement to remove quagga muscles for material to be disposed? | For purpose of mitigating invasive plant species (i.e. equipment inspection), clean and have inspected truck, trailer, and boat before use. But for purpose of NDOW AIS prevention program (i.e. quagga mussel prevention), decontaminate boat AFTER final use before leaving work area (i.e. you do not need to decontaminate boat after each use as long as it remains at work area but decontaminate boat during demobilization). The contractor is responsible for their own inspection and decontamination for their equipment leaving the site and compliance with appropriate decontamination and disposal requirements based on the authorities having jurisdication (Nevada Department of Wildlife Aquatic Invasive Species Prevention Program) / waste management facility requirements. (01 74 19 3.6.A) |
01 74 19 3.6.E "Disposal of the existing barge and materials that have been in contact with lake water shall include all decontamination procedures to control invasive species that are in effect at the time of the work."
30 SECTION 01 50 00 - TEMPORARY FACILITIES AND CONTROLS, 2.2 TEMPORARY FACILITIES, B. Contracting Officers Field Office: Field office shall be a separate structure from Contractor's office. Are we expecting the Contracting Officer to be in-field and need an in-field office? A construction management representative (CMR) as a representative of the CO will be onsite full time and will require a field office space.
Toilet facilities should be provided as stated in the specifications which are in accordance with OSHA work site requirements (https://www.osha.gov/restrooms-sanitation) for ventilation, lighting, and accessibility for the contractor and CMR's use. Note the spec says sufficiently ventilated and does not mention heating or cooling. Standard portable toilets usually meet these requirements.
The referenced specification is our standard division 01 language. For this project, the intent is that the contractor provide high-speed internet to the field offices such that weekly construction progress meetings can be held virtually on teams and the CMR and contractor can access the construction management software site to post reports, submittals, RFIs, etc.
| D. Toilets: Sufficiently lighted and ventilated toilet facilities in weatherproof, sight proof, handicap accessible, sturdy enclosures with privacy locks. | ||
| Provide separate toilet facilities for men and women. | ||
| Are we expected to have facilities for separate for men and women that are heated and air conditioned and handicap accessible as stated? | ||
| 2.3 EQUIPMENT, C. Are we Required to provide DSL internet Service for the Project? | ||
| 31 | Do we have an estimated weight on the existing Barge to be demoed? So we know whether or not it has to be disassembled or a crane can just lift it out? | Weight of existing barge is unknown. An as-built drawing of the barge for dimensions and layout from a 2017 pump replacement project is provided as an attachment in addition to the photo located on drawing E3, Detail 7. |
| 32 | Are there lift points on the Barge for rigging already? | There are no lift points on the barge. |
| 33 | Are we able to abandon the existing anchors in place? | Yes, abandoning the existing concrete anchors in-place is acceptable. Retrieval and proper disposal/recycle of all cables/chains that are attached to anchors is required. |
| 34 | Will there be a designated staging area provided for construction staging and storage? If so, please indicate where this area will be within the marina including dimensions. | See response to #28 and attached figure. Area is roughly 150ft x 700 ft. |
| 35 | During the mobilization/demobilization stages, will there be availability to close a portion of the boat landing for construction operations? |
As per Sheet G2, Site Specific Notes No. 8; contractors will be limited to closing the boat launch for half-days on Tuesday, Wednesday, and Thursday. Please verify the boat launch cannot be closed, for any duration, Friday through Monday.
| Contractors will be required to set-up/teardown cranes, launch/recover barges and equipment, launch the new intake barge, and remove the abandoned/existing intake barge; therefore, we have concerns about the limited utilization of this boat launch to complete these activities in an efficient, cost-effective manner. | See response to #27 and the alternative water access point shown in the figure attached to #28. | |||
| 36 | As per Sheet G2, Site Specific Notes No. 11; “[p]eak season for visitors at Callville Bay is between Memorial Day and Labor Day. Limitations for construction activities may arise when the contractor requires interruption of normal park operations, such as closure of the boat ramp, during this period.” Can the boat launch be closed for extended durations outside of the peak season? | See response to #27 | ||
| 37 | When visiting the Callville Bay boat launch recently, there was on-going construction occurring on the boat ramp. When will this construction project be completed? Could updated design and/or as-built plans be released for review? Information about the geometry of the boat ramp, as well as nearby topography, would be invaluable to prospective bidders. | The construction (grading) that was done by Concessioner is complete. There are no drawings, the Concessioner only graded the area. Drawings from the last boat ramp project at Callville Bay are provided for reference as an attachment to this amendment. | ||
| 38 | When visiting the Hemenway Harbor boat launch recently, our representative spoke with a local fish and game officer who stated the lake level will be lowered to facilitate renovations on the boat launch/landing. Please confirm if the lake level will be lowered to facilitate this project. What are the starting and ending dates for this project? Can the planned water elevation be provided for the construction phase? | Lake levels will not be lowered to facilitate this project. Lake levels are not within control of NPS and are constantly changing as they are dependent on snowpack, snowmelt, water use/demands upstream and downstream of the reservoir and power generation needs. A 2 year projection is updated monthly by the bureau of reclamation as referenced in #3. The construction of the Hemenway Harbor boat ramp extension is currently underway and is anticipated to continue until May 2026. | ||
| 39 | Can the Hemenway Harbor boat launch be utilized as an alternate access/egress location for the project? Would the same conditions also apply to this location? | The boat ramp extension project at Hemenway Harbor already reduces the capacity of that boat ramp for the public's use and is not available for the contractor's use with the exception of launching of a single boat following all launching procedures required of the general public. | ||
| 40 | The solicitation states the following, “Submit your schedule in Gantt Chart format, assume a Notice to Proceed date of 03/01/2025, and include specific activities required for this project and a clear critical path with major milestones and applicable predecessor activities.” Since the Notice to Proceed (NTP) date has passed, shall the Offeror still use 03/01/2025 or use another NTP date to compile a Gantt Chart with milestones and activities? | Please assume a Notice to Proceed Date of September 1, 2025. | Amendment 6, FINAL Q&A posted 6.5.25 |
