This is confirmation that only one electronic copy of each volume is required.

Section L, Volume I, Factor 6 requires offerors to submit a Past Performance Questionnaire (PPQ) or a CPARS evaluation report. Can offerors submit a previously completed PPQ rather than requesting that a reference complete new PPQ form? This will help reduce the burden on references by requiring them to complete a separate, distinct PPQ form for each procurement effort.

A previously submitted Past Performance Questionnaire can be submitted.

Solicitation Attachment “B08_Attach_06_Solit_PSP_Cover” includes a reference to “2.

Section H Special Requirement 3: Key Personnel identifies four key personnel positions, including Job Site Superintendent, Job Site Quality Control Manager and Job Site Safety Manager. Furthermore, Section L, Volume I, Factor 5 – Key Personnel Experience, identifies that key personnel resumes be provided for the Superintendent, On-site Quality Control Specialist and On-site Safety Specialist positions. Is it acceptable for the Safety Manager/Specialist role to be dual-hatted with either the Quality Control Manager/Specialist or the Superintendent?

Yes, QCM may also act as SSHO. Superintendent shall only perform superintendence of the project.

Section B, RFP page 9 of 84, provides a Bid Schedule for this project. Within the instructions on page 9, the RFP states, “Please complete Attachment XX Contract Price Schedule (include this sentence if not using table below).” Although not referenced in this statement, a separate Excel file (Attachment 05) was also provided with the Bid Schedule. Furthermore, Section L, Volume II states, “SECTION B CONTRACT PRICE SCHEDULE or ATTACHMENT X CONTRACT PRICE SCHEDULE.” Can the government please clarify if offerors should complete page 9 of the RFP or the separate Excel attachment?

Factor 3 Management Approach is limited to 5 pages yet establishes requirements for four distinct areas, including Capacity, Roles and Responsibilities, Risk Mitigation and Safety.

The response to the Safety requirement alone will exceed 5 pages since it requires an overview of the Company Safety Program, a resume for the Project Safety Manager, a copy of OSHA Logs for the past three calendar years and a statement from the insurance company with the current Experience Modification Rate (EMR). Can the government respectfully consider excluding the safety requirements from the 5-page limit specified for Factor 3 Management Approach?

Yes. Safety will be excluded from the 5 page requirement.

RFP page 81 of 84, Volume II, 3. Contents, Section B states, “Also provide a separate Schedule of Values (SOV) for each line item in the Section B Contract Price Schedule.” As there is only one line item on the bid schedule, are the major work components’ breakdown on the SOV to equal the single CLIN’s lump sum total?

Yes.

The specifications call out for the spoolable composite pipe and associated fittings to be rated to 2,500 PSI and 3,000 PSI with an NSF 61 rated inner liner. After speaking with manufacturers it does not appear that this is possible in a 6" diameter pipe. Also, no NSF 61 rated air valves appear to meet this pressure requirement either. Can you please confirm the pressure rating on this project and provide a list of approved manufacturers for the pipe and fittings?

We know FlexSteel has 6" pipe meeting all the requirements for both 2,250 psi and 3,000 psi composite pipe. Vent-O-Mat RBX, Double Orifice with Anti Shock orifice is one supplier we had found for the air release valves. Per Spec 40 05 52 the working pressure requirement for the air release valves is 750psi.

Bore #2 (4,462’) Clarification Requests - Per drawing sub-sheet C38, the HDD set up area is identified. Per our Drilling Engineer, more space is needed. Is there any way the pipe exit area can move closer to 168+00 station to allow for more work area space and staging for successful bore? What are the client’s recommendations for more space.

No. Significant Archaeology exists in this location. if needed additional space may be allocated closer to 169+00 and 170+00. Expansion of the LOD request can be made once exact needs are presented by the contractor but space is limited by cultural resources and topography.

Bore #2 (4,462’) Clarification Requests - Casing – Use poly instead of steel?

a.33 05 07-10 Horizontal Directional Drilling: 2.2 E Wash-Over Casing shall confirm to

ASTM A252 Grade 2 Steel and be manufactured specifically for the method of installation b.Flexsteel recommendation is HDPE casing compared to steel for various technical reasons.

Contractor can propose an alternate casing pipe type for review/approval after award. If HDPE can meet casing requirements per specifications it may be considered. See 'submittal procedures' 01 33 23 (1.3)(E)

Reference Question Official Response - DSC

Bore #2 (4,462’) Clarification Requests - Casing – Use slick bore (not using casing) instead of poly or steel?

a.Per appendix A in specifications, bore calls for 12” ream pass. If slick bore is allowed, will this 12” minimum still be required?

Contractor can propose an alternate to casing for review/approval after award. If slick borer can meet casing requirements per specifications it may be considered. See 'submittal procedures' 01 33 23 (1.3)(E)

Bore #2 (4,462’) Clarification Requests - What are the client’s concerns if any about preloading the Flexsteel inside the casing prior to pulling the casing through the bore section?

Per our drilling engineer the best recommendation for a successful bore is to preload the casing specifically from station 123+00 to 77+00 across the entire ROW.

See specification 33 05 07.

The Contractor shall submit any proposed changes to the plan orientation per the specifcation prior to beginning HDD work. Due to resource concerns the bore needs to terminate in the shown drilling setup area around station 169+00-170+00.

Bore #2 (4,462’) Clarification Requests - Per drilling engineer recommendations, extensive dirt work will need to be completed to ensure a successful bore of bore #2. What are the expectations and requirements for the extensive dirt work needing to be done and the carbon footprint of change behind the extensive dirt work? This question is directly related to the boring lay down area at 170+00.

The Contractor will need to submit their excavation plan within the boring lay down area for approval prior to work in that area per specification 33 05 07. Excavation monitor requirements are called out in the Division 01 specifications also.

Bore #2 (4,462’) Clarification Requests - What are the stipulations behind using the Mesa Top Ruins Road for pipe staging and other necessary steps to complete bore 2 successfully?

Can the road be completely closed for a certain amount of time or can half of the road be closed for an extensive amount of time if contractor provides sufficient road traffic.

Mesa Top Ruins Road cannot be completely closed. Half of the road can be closed with appropriate traffic control with delays not exceeding 15 mins, 24/7. Any damage to roadway from staging of material will need to be repaired to match existing condition

Requesting a bid date be extension for 2 weeks or longer, do to increment weather the week of 01/ 19/2026 delayed a site visit. 1A Do to subcontractors and or suppliers our company has reached out to requesting sub-quotes or materials quotes are unaware of the project being out to bid. Most have requested additional time or days in order to prepare quotes. We have been contacting said companies starting on January 15, 2026 for quotes.

An extension is granted and the proposal due date is now 2/26/2026.

Concerning the budget stated or shown on Sol 140P2026R0020 of 5 to 10 million is this corrected?

The rough order Magnitude of this project is between $5M-$10M.

The elevation shown on the profile plans for the 6 inch pipe being installed by HDD method, Will NPS, DSC Contracting Services consider changing the HDD pipe elevation to 4 foot of cover to the top of pipe, similar to the open trench elevation as shown on the water line profile plan sheets on the HDD drawing?

No.

The following stations the existing 6 Inch line appears to be in conflict with the new 6 inch waterline, elevations and pipe locations, if the waterline cannot be shut down for more than 1 to 2 hours what are acceptable means and methods to install the new waterline if conflicts of this nature between existing and new waterline. The following stations are estimated 52+75 to 53+00, 61+00 to 62+00, 67+50 to 68+25, 70+75 to 74+25 and 75+50 to 76+20.

Review the plans, none of the locations listed have the new waterline closer than 10' from the existing water line. There is a crossing identified at approximately 47+90 with callouts to adjust grade of the new line as needed to provide 1' of clearance.
