Redwood tank repair limits

01 27 00, 3.1.D; 01 35 91, 3.3

CLIN 4 defines specific minor repairs, while the contractor-prepared Historic Structure Report must recommend additional preservation work. Contractor requests NPS create an allowance or force account budget to cover the repairs noted by the contractor-prepared Historic Structure Report. It is difficult to quantify the value of this work prior to bid, which may result in wildly different assumptions by the contractors bidding the work.

An allowance or force account budget is not considered at this time. The work included in the CLIN 4 lump-sum price consists of the assessment and Historic Structure Report together with the specific preservation and repair work identified in the Contract Documents, including cleaning and treatment of the redwood staves, replacement of the bottom two steel hoops/tension rods, vegetation and soil removal, grading, stone-wall vegetation removal, and associated drainage work. The Historic Structure Report shall document existing conditions and identify and prioritize additional preservation recommendations in accordance with Section 01 35 91. Recommendations contained in the Historic Structure Report that are beyond the repair work specifically identified in the Contract Documents are not included in the CLIN 4 lump-sum scope unless separately authorized by the Contracting Officer. If conditions are identified during the assessment that warrant additional work, the Contractor shall notify the Contracting Officer and shall not proceed with such additional work unless directed in writing via a contract modification.

Asbestos pipe pricing basis 01 11 00, 1.12.B; 02 82 00; C2-C7, Note 12;

Hazardous Material Survey

The underground cement pipe was inaccessible during the hazardous materials survey and must be tested. Because the actual dispensation of the material cannot be determined until the pipe is exposed and tested, contractor requests an allowance or force account buget to cover this cost. It will be difficult to compare bids if all parties use different assumptions for the amount of material ultimately removed.

For bidding purposes, assume approximately 318 linear feet of underground 24-inch pipe is Asbestos Cement Pipe (ACP) and shall be removed and disposed of properly. Include testing to confirm pipe material prior to disturbance or removal.

Existing cesspool suitability

01 27 00, 3.1.B; C61-C62

Please provide available records and investigations establishing the existing cesspool dimensions, condition, and suitability for conversion to the proposed seepage pit. Identify required testing, rehabilitation, and acceptance criteria, and clarify the scope if field investigation determines it cannot serve the proposed system.

Existing dimensions and condition of cesspool are unknown. Testing, rehabilitation, and acceptance criteria shall be in accordance with Hawaii DOH regulations. Septic tank installation shall be performed by HI certified installer.

Foundation voids/unsuitable material

Geotechnical Report, Sections 6-7; 31 20 00

The geotechnical report identifies subsurface voids and soft pumice/tephra and recommends verification and remediation. Please identify the required investigation method and extent beneath proposed foundations, the design criteria/details for void remediation, and the bid quantities or limits for removal and replacement beyond the depicted foundation excavations.

Refer to detail for filling voids on Civil sheets, 9/C23. No void quantity is available at this time. There is no required investigation of the area, only filling voids if/as they are found in project excavation.

22,000 GPD

measurement/baseline

01 11 00, 1.9.F; Construction Phasing Memo/Calcs

Please define where and over what period compliance with the 22,000 GPD minimum will be measured. Provide current usable storage capacities, normal operating levels, and recent water demand/production data, and confirm whether the issued phasing analysis remains the Government accepted planning baseline.

The 22,000 gallons-per-day requirement is a system-wide minimum water-supply requirement and is not intended to be measured at a single catchment, slow sand filter, tank, or other individual component.

In accordance with Section 01 11 00, the Contractor shall maintain the Park water system's ability to provide a minimum of 22,000 gallons per day for the duration of the Project. Compliance may be achieved through continued operation and sequencing of the existing collection, treatment, storage, and distribution system and, when approved by the Contracting Officer and coordinated with Park Water System Operators, through temporary bypass piping and/or potable-water hauling.

The Park has approximately 1,000,000 gallons of usable potable-water storage. Storage tanks are normally maintained at high operating levels and are to be filled to capacity, to the extent operationally practicable, before major water-system components are taken offline. The existing slow sand filtration system has a maximum production capacity of approximately 32,000 gallons per day under normal operating conditions.

Refer to the HAVO 326181 Construction Phasing Memo and supporting calculations for the Government's accepted planning basis for construction sequencing. The analysis assumes conservative low-rainfall conditions and increased water demand and concludes that up to two of the following may be taken offline simultaneously while maintaining water service: Ground Catchment 1, Building 241, and Building 43. All three shall not be taken offline simultaneously.

The Contractor shall develop and submit a project-specific Phasing Plan with the Construction Baseline Schedule demonstrating how the 22,000- GPD requirement will be maintained throughout construction. Actual sequencing and proposed interruptions remain subject to coordination with and approval by the Contracting Officer and Park Water System Operators.

Shutdown windows

01 11 00, 1.9.C; C60

Utility outages are limited to two to four hours. Please confirm whether this limit applies to isolation of individual treatment components and the pump/control replacement work shown on C60, and identify whether longer coordinated shutdowns may be approved where finished-water service remains available.

The limit does apply, however, longer coordinated shutdowns will be considered upon request.

Sand filter return-to-service

46 00 00, 3.7-3.8; C53

Section 46 00 00 requires filter-to-waste operation until the filter matures and turbidity is below 1 NTU. Please confirm any additional sampling, biological maturation, duration, or DOH approval requirements before returning each filter to service. Identify the approved discharge location and responsibility for operating and monitoring the filter during maturation.

Turbidity monitoring is the recommended method for filter maturation based on AWWA standards/manuals. DOH Surface Water Treatment Rule requires filter-to-waste during filter maturation, but does not include specific requirements for monitoring. Coordinate discharge location with Contracting Officer.

Historic tank interior access

01 35 91, 3.3

The Historic Structure Report requires assessment of interior and exterior architectural and structural elements. Please confirm whether entry into each redwood tank is required and identify available access and safety requirements, considering the current state of some of the tanks.

Section 01 35 91 requires the Contractor-prepared Historic Structure Report to include an existing-conditions assessment of both exterior and interior architectural and structural elements of the five historic redwood water tanks. The Contract does not specifically require personnel to physically enter each tank.

The Contractor's qualified Historic Preservation Treatment Specialist shall propose, as part of the Historic Preservation Treatment Plan, the means and methods necessary to obtain sufficient information to document and assess the interior and exterior condition of each tank. The assessment method shall minimize risk to personnel and avoid damage to historic materials. Remote inspection methods may be proposed where they provide adequate information to satisfy the Historic Structure Report requirements. Additional non-destructive or minimally invasive investigative methods may also be proposed where appropriate and shall be subject to Government review prior to use.

If physical entry into a tank is proposed or determined necessary, the Contractor shall comply with the confined-space and other applicable safety requirements of the Contract and OSHA. The Contractor is responsible for determining and implementing the appropriate access, fall-protection, confined-space, rescue, and other safety measures associated with its proposed means and methods.

Use of an Uncrewed Aircraft System (UAS) is not required by the Contract. If the Contractor proposes UAS as an inspection method, its use is subject to prior NPS authorization and all applicable FAA, DOI, and NPS requirements, including NPS Reference Manual 60 and DOI OPM-11. Any proposed UAS must comply with applicable DOI/NDAA restrictions regarding covered UAS, and the required UAS safety and authorization documentation shall be submitted and approved before operation within NPS boundaries.

The supplemental Redwood Water Tanks Vanishing Treasures Report provides prior condition information and treatment recommendations for reference; its recommendations do not independently expand the construction scope beyond the requirements of the Contract Documents.

Geotextile discrepancy

33 47 13, 2.2; C57; Basis of Design Product Files

The drawings and specifications require 32 oz/sy nonwoven geotextile, while the Basis of Design Product Files identify 30 oz material. Please confirm whether 30 oz material meeting the remaining specified properties is acceptable or whether 32 oz/sy is mandatory.

32 oz/sy material is included in the Basis of Design Product Files (page 203) and is required.

Septic/treatment approval status

01 31 00, 1.9; C61-C62; 46 00 00

Section 01 31 00 lists no Government-furnished permits. Please identify existing design approvals and outstanding agency approvals for the septic/seepage system and potable-water treatment modifications, including which submissions require Government/design-team action and which are contractor responsibilities.

No separate Contractor permit application is required for Government design approval of the septic/seepage system or the water-treatment modifications shown in the Contract Documents. NPS will coordinate required NPS Office of Public Health/Public Health Consultant review and any required coordination with the applicable primacy agency.

Construct the septic/seepage system in accordance with Sheets C61-C62 and Section 33 34 00, and perform the water-treatment work in accordance with the applicable Contract Documents.

The Contractor remains responsible for permits, approvals, and utility coordination expressly assigned to the Contractor by the Contract Documents or resulting from the Contractor's means and methods, including applicable electrical utility hookup, temporary utility, stormwater, and NPDES requirements.

Contract completion dates

Solicitation SF1442, Block 11 (p.1); continuation sheet (p.3); H, Special Requirement 1 (p.15)

The solicitation includes a 610-day period after NTP, CLIN performance dates of November 1, 2026- July 3, 2028, and a December 21, 2028 delivery date. Please confirm that 610 calendar days after actual NTP governs completion and identify the anticipated award/NTP dates for proposal scheduling.

The contract duration is 610 calendar days from the Contractor's receipt of the Notice to Proceed. Any calendar dates identified in the solicitation that are inconsistent with the 610-calendar-day duration will be revised by amendment.

The 610-calendar-day period is the Contract Period and is not intended solely as the date for achieving Substantial Completion. The Contractor shall plan and prosecute the Work so that all contract requirements necessary for completion are accomplished within the Contract Period. Except for the post-construction archeological reporting process addressed in RFI 103 and Section 01 35 13.22, as revised by Addendum No. 1.

In accordance with Sections 01 32 16 and 01 77 00, the Contractor's schedule shall include startup, testing, inspections, commissioning, required closeout submittals, Substantial Completion procedures, punch-list work, and final completion/acceptance activities. Substantial Completion shall therefore be scheduled sufficiently in advance of the Contract End Date to permit completion of the remaining punch-list and closeout activities within the Contract Period.

The Contractor shall complete punch-list work within 30 calendar days following Substantial Completion, but in no event shall that provision extend the Contract Period unless an extension is authorized by the Contracting Officer.

Anticipated award and NTP dates cannot be provided at this time; however, if this changes, please note any dates provided are planning dates only and will be identified/updated by amendment as appropriate. The actual Contract End Date will be established from the actual NTP date based on the 610-calendar-day Contract Period.

JV experience/self-performance

Solicitation L, Project Experience/Past Performance;

H, Special Requirement 2

Please confirm how projects performed by individual JV members will be evaluated under Project Experience and Past Performance, including the documentation required to establish their relevance to proposed responsibilities. Also confirm whether on-site work performed directly by either JV member counts toward the prime contractor 15% self-performance requirement.

Confirmed. For an offer submitted by a joint venture, the joint venture is the prime Offeror/Contractor. The individual firms comprising the joint venture are joint-venture members and are not considered subcontractors to the joint venture solely by virtue of their status as JV members.

For purposes of Project Experience and Past Performance, relevant experience and performance of the joint venture itself and of the individual JV members may be submitted and will be evaluated in accordance with the solicitation. The proposal should identify the JV member that performed each cited project, describe that member's role and responsibilities, and explain the relevance of that experience to the work the member is proposed to perform under this contract.

For purposes of Section H, Special Requirement 2, on-site work performed directly by the joint venture through either of its JV members will be considered work performed by the prime Contractor toward the 15 percent self-performance requirement. Work performed by subcontractors to the joint venture or to its individual members does not count as prime-contractor self-performance.

Equipment warranties with proposal

46 00 00, 3.6.A; Solicitation L

Section 46 00 00 requires equipment warranties as part of the bid submittal package. Please confirm which equipment warranties must accompany the proposal, whether supplier standard warranty documents are sufficient, and where these documents should be included within the prescribed proposal volumes/page limits.

Section 46 00 00 applies to the water-treatment equipment identified in that section, including the associated pumping equipment. The intent of Paragraph 3.6 is to establish the minimum warranty requirements applicable to the equipment furnished under the Contract. Warranty documentation is not required with the offeror’s proposal. Prior to approval of the applicable equipment submittal, the Contractor shall provide manufacturer/supplier warranty documentation demonstrating that the proposed equipment complies with the warranty requirements of Section 46 00 00, Paragraph 3.6. Manufacturer or supplier standard warranty documentation is acceptable provided it demonstrates compliance with the specified requirements. Where the standard warranty does not expressly satisfy all requirements of Paragraph 3.6, supplemental documentation shall be provided confirming compliance. Final approved warranties shall also be included in the applicable Operation and Maintenance documentation in accordance with the Contract requirements.

Proposal deadline/time zone

If so, identify the controlling contract/funding provision, covered products, required manufacturer certifications, and applicable exemptions or waivers. If no additional requirements apply, please confirm the cited FAR provisions govern domestic sourcing.

The solicitation incorporates FAR 52.225‑11, Buy American—Construction Materials Under Trade Agreements, and FAR 52.225‑12, Notice of Buy American Requirement—Construction Materials Under Trade Agreements. These clauses constitute the sole domestic preference requirements for this project.

HDPE substitution

33 40 00 - Storm Drainage, 2.1.A.1 (33 40 00-1)

Section 33 40 00, paragraph 2.1.A.1 requires PE4710 HDPE meeting ANSI/AWWA C906, ASTM F714, and ASTM D3035, with ductile iron pipe size (DIPS) DR21. A supplier reports that the specified DIPS pipe is unavailable for the small project quantities and proposes 36-inch IPS DR17 and 10-inch IPS DR17 as alternatives. Please confirm whether these sizes and dimension ratio are acceptable for the corresponding rainwater collection pipe runs, subject to compliance with the specified resin and applicable standards. Please identify any required revisions to nominal sizes, hydraulic capacity, connection details, fittings/adapters, collection-box penetrations, and supports. This request concerns the solid-wall DIPS HDPE specified in Section 33 40 00 and does not propose substitution of the separate corrugated HDPE catchment piping.

8" HDPE and 30" HDPE pipe covered in Section 33 40 00, paragraph 2.1.A.1 can be ASTM D3350, AASHTO M294. Profile wall – Type S, 2 ft minimum burial depth, 10 ft maximum burial depth, bell and spigot joint with water-tight, non-cleating, O-ring gasket, ASTM F477.

QC Supervisor conflicting requirements

Section 01 40 00, Quality Requirements, paragraphs 1.5.B.1–3 (page 01 40 00-4)

Paragraph 1.5.B.1 permits the Contractor’s Quality Control Supervisor to perform other duties, while paragraph 1.5.B.2 requires the same individual to be assigned no other duties. Please clarify which requirement governs. May the Quality Control Supervisor hold another project role, provided the required QC responsibilities and on-site presence are maintained, or must this individual be dedicated exclusively to quality control? Please revise the conflicting provisions accordingly.

Paragraph 1.5.B.2 governs. The Quality Control Supervisor shall be dedicated to the quality-control function and shall not simultaneously serve in another primary project role, including Project Manager, Superintendent, or SSHO. Paragraph 1.5.B.1 will be revised to eliminate the conflicting language.

Reuse of concrete/asphalt

Section 01 74 19, Construction Waste Management and Disposal, paragraphs 1.3.B and 1.4.B, and attached worksheet identifying the 60% diversion goal; Section 31 20 00, Earth Moving, paragraph 2.2.

To support the project’s waste diversion goal, will the Park permit concrete and asphalt generated by project demolition to be processed and reused on site as crushed concrete aggregate or asphalt millings, or stockpiled off site for Park maintenance personnel to use elsewhere? Reinforcing steel will be removed from the concrete and segregated for recycling.

Please identify acceptable uses, approved stockpile locations, and any required processing, gradation, testing, or environmental acceptance criteria. For material retained for future Park use, please clarify responsibility for hauling, stockpile management, and acceptance. Please also confirm whether either approach will count toward the project’s waste diversion goal and identify the documentation required to receive that credit.

The park does not want concrete aggregate or asphalt millings. Concrete aggregate can be used for construction purposes, as applicable and appropriate, however, all extra material must be removed from the park and disposed of legally. Asphalt millings cannot be reused unless directly under location where asphalt will be placed. It cannot be used for shouldering.

Past-performance questionnaires Solicitation Section M.B.3, Past Performance Evaluation (page 59); Section L, Volume I, Factor 2 – Past Performance (page 57); Section L, Volume II, General References (page 58); Attachment 12, General References.

Section M.B.3 states that past performance will be evaluated using survey responses, CPARS data, and other relevant information. However, no project-specific past performance questionnaire or survey form appears to be included in the solicitation attachments. The provided General References form is identified in Section L as supporting the responsibility determination. Please confirm whether offerors must distribute or submit past performance questionnaires, or whether the Government will independently contact project references identified in the proposal. If questionnaires are required, please provide the form and instructions identifying who submits completed responses, the submission method, and the deadline.

The language in Section M.B.3 referencing the use of past performance survey responses was included inadvertently and does not apply to this solicitation. In accordance with our updated internal policy, the Government is not utilizing, reviewing, or completing any past performance questionnaires or surveys for this requirement. For that reason, no project‑specific past performance questionnaire was included in the solicitation package. Offerors are not required to distribute or submit past performance questionnaires. The Government will evaluate past performance using CPARS data and any other information that is readily available to the Government through existing sources. The General References form identified in Section L applies only to the responsibility determination and does not serve as a past performance survey instrument.

Utility coordination/allowance

Section 01 73 40, paragraphs 3.2.A.1 and 3.2.A.4;

Section 01 31 00, paragraphs 1.9.C.1–2; Section 01 27 00, paragraph 1.1.C.

The specifications assign Hawaiian Electric and Hawaiian Telcom service coordination to the contractor and require the contractor to carry all utility fees and charges associated with service upgrades. Based on experience during previous project phases, these utilities require the account holder/ratepayer to initiate service requests. The contractor has no direct contractual relationship with the utilities and cannot independently obtain binding commitments for scope, pricing, or service dates. Utility charges were therefore addressed through an allowance in previous phases.

Please confirm that NPS will initiate the required service requests as the account holder and authorize contractor coordination thereafter. Please also establish a common allowance for utility-company charges for proposal pricing, identify the costs covered by that allowance, and specify how actual charges above or below the allowance will be reconciled. If an allowance will not be provided, please furnish the utility-approved scope and binding pricing commitments on which offerors are to base their lump-sum proposals.

The existing Building 43 electrical service shall remain a 1-phase, 200-amp overhead service. The Project does not increase the service size or change the existing voltage or phase.

The Contractor shall replace the existing meter base and…
