# Question Response

SF-1442 block 13.a refers to "Sealed offers in original and 1 copies," while Section L paragraph D.1 states "Proposals shall be submitted via email. Proposals submitted via any means other than email shall not be accepted," paragraph F.1 states "No hard copies shall be submitted," and 52.228-1(a) states that "Failure to furnish a proposal guarantee in the proper form and amount, by the time proposals are due, may be cause for rejection of the proposal." The offeror interprets Section L as governing and intends to transmit with Volume II a PDF of the SF 24 (Attachment 08) executed by the offeror and the surety, with the surety's power of attorney, and no wet-ink original. Does that submission satisfy 52.228-1?

Yes, please submit everything electronically through email.

Amendment 0003 states "The proposal due date is extended to 13 Nov 2026 at 5:00PM EST," and Section L paragraph B states "Pre-proposal questions shall be submitted a minimum of 7-days prior to the due date and time for proposals." Amendment 0004, posted on SAM.gov on October 28, 2026, revises Appendix C §1.c, answers RFIs #52 through #69 and marks the proposal due date as "is not extended." The offeror interprets the responses to these questions on the low-tide restriction, on excusable time for days lost to tide and on the Notice to Proceed as determining the Factor 2 schedule and Volume II pricing. Will the Government extend the proposal due date to not less than 14 calendar days after the date of the amendment that responds to these questions?

Questions remain due on Nov 6, 2026 @ 1700EST. No additional extension will be granted. The proposal due 11/13/2026 @ 1700 EST

Section L Factor 7 item 1 directs offerors to "Direct them to complete and submit the survey to the address and point of contact in paragraph B above," and paragraph B lists joseph_wingfield@ios.doi.gov and marlon_bynum@contractor.nps.gov, while Attachment 06 (as revised by Amendment 0002) directs the questionnaire to "Joseph_wingfield@nps.gov." The offeror interprets both routes as acceptable and will instruct references to send to all three addresses. Will a questionnaire received at any of those three addresses by the due date be considered?

Only send to joseph_wingfield@ios.doi.gov and marlon_bynum@contractor.nps.gov

52.219-14(e)(3) provides that the Contractor "will not pay more than 85 percent of the amount paid by the Government for contract performance, excluding the cost of materials, to subcontractors that are not similarly situated entities," while Attachment 10 computes cell C26 as (C12 − C24)/C12 with no entry for the cost of materials, and Section M paragraph C.3.g states "This worksheet will be reviewed for completeness and correlation to proposed pricing." 13 CFR 125.6(a)(3) states "Cost of materials are excluded and not considered to be subcontracted." The offeror interprets the clause test as excluding the cost of materials from both amounts. May offerors submit with Attachment 10 a supplemental computation that excludes the cost of materials as 52.219-14(e)(3) provides?

Yes exclude the materials.

Section I includes 52.222-55, Minimum Wages for Contractor Workers Under Executive Order 14026 (DEVIATION MAY 2026), requiring "a minimum hourly wage rate of $15.00 per hour beginning January 30, 2022," while Executive Order 14026 was revoked by Executive Order 14236 of March 14, 2025, and Attachment 04 (WD FL20260202) carries only an Executive Order 13658 note. Paragraph (b)(2) of the clause states "The applicable published E.O. minimum wage is incorporated by reference into this contract." The offeror interprets the clause as applying as written unless deleted and will price the last annual rate published under paragraph (b)(2), $17.75 per hour effective January 1, 2025 (89 FR 79644), on classifications listed below that rate. Will the Government confirm by amendment whether 52.222-55 applies to the resulting contract?

The applicable minimum wage requirements are those associated with EO 13658, as identified in Wage Determination FL20260202. The current EO 13658 minimum wage rate is $13.65 per hour, effective May 11, 2026. Offerors should price their proposals accordingly.

Section L Factor 2 states "for evaluation purposes only assume a Notice to Proceed date of 4 January 2027" but states no award date. Section 01 32 16 para. 1.3.C requires the Construction Baseline Schedule "After contract award and before Pre-Construction conference," and Section 01 33 23 para. 1.3.D.1.a requires offerors to "Allow 30 days for initial review of each submittal." The offeror interprets Factor 2 as permitting the schedule to show submittals due after award and their Government reviews before 4 January 2027. What contract award date should offerors assume for the Factor 2 schedule?

For schedule submission assume NTP is 10 days after contract award.

Section 01 31 00 para. 1.4.D lists "Division 1 submittals required prior to mobilization," and Section 01 32 16 paras. 1.3.B and 1.3.C require the Schedule of Values and the Construction Baseline Schedule "After contract award and before Pre-Construction conference," and Section 01 32 16 para. 2.2.A.1 requires the baseline to be developed "so it can be accepted for use no later than 30 days after date established for the Notice of Award." The offeror interprets these as permitting submission between contract award and the Notice to Proceed that starts the 259-calendar-day period so that the 30-day initial review under Section 01 33 23 para. 1.3.D.1.a can run before that period begins. May the Contractor submit the Division 1 submittals after contract award and before the Notice to Proceed that starts the 259-calendar-day period?

Yes, Division 1 submittals should be submitted after contract award and before NTP is issued.

Section 01 31 00 para. 1.7.A lists among the preconstruction conference agenda items "Resolution of comments on required Division 1 documents" (item 4) and "Notice to proceed" (item 14), SF-1442 block 11 requires the Contractor to "complete it within 259 calendar days after receiving" the notice to proceed, and Amendment 0004 RFI #64 states "A limited NTP can be provided to start the permit application." The offeror interprets the Division 1 submittals and their Government review as work that may proceed under a limited Notice to Proceed before the Notice to Proceed that starts the 259-calendar-day period. Will the Government issue a limited Notice to Proceed at contract award for preparation, submission and review of the Division 1 submittals?

If a limited NTP is issued for the permit application then Division 1 submittals can be submitted and reviewed during that time.

SF-1442 block 11 requires the Contractor to "complete it within 259 calendar days after receiving" the notice to proceed, Section H Special Requirement 1 requires completion of "the entire work ready for use not later than 259-calendar days after receipt of notice to proceed," and Amendment 0004 RFI #64 states "A limited NTP can be provided to start the permit application." The offeror interprets a limited Notice to Proceed as authorizing only the work it names, with the 259-calendar-day period measured from the Notice to Proceed for construction. Does a limited Notice to Proceed issued under Amendment 0004 RFI #64 start the 259-calendar-day period in SF-1442 block 11?

No it does not start the actual work time.

Section 01 31 00 para. 1.9.B lists the SJRWMD Environmental Resource Permit 224839- 1, a "401 Water Quality Certification (WQC) with identification number TBD," and the Submerged Land Lease Letter of Consent as Government-furnished permits, and Amendment 0002 RFI #45 states the "SJRWMD ERP permit is currently in process."

Nationwide Permit General Condition 25(b) provides that, where the certifying authority has not previously certified compliance of an NWP with CWA section 401, an activity that may result in a point-source discharge "is not authorized by an NWP until water quality certification is obtained or waived." The offeror interprets work below the high tide line as not authorized until those permits issue. Will the Government withhold the Notice to Proceed that starts the 259-calendar-day period until the ERP, the 401 Water Quality Certification and the Submerged Land Lease Letter of Consent have been issued?

Yes.

Section H Special Requirement 1 requires completion of "the entire work ready for use" within 259 calendar days and states "The time stated for completion shall include final cleanup of the premises," while Section 01 77 00 para. 1.4.B states "If work is determined substantially complete, following final inspection, Contracting Officer will prepare Punch List and issue a Letter of Substantial Completion" and para. 1.4.D states "Contractor shall complete Punch List within 30 calendar days." The offeror interprets the 259-day completion requirement and the 52.211-12 liquidated damages period as measured to the date of Substantial Completion in the Contracting Officer's letter under para. 1.4.B, with the 30-day Punch List period following that date. Is that interpretation correct?

Yes

Section 01 32 16 para. 2.2.B.7.d.3 states "Weather days shall be based on data for local area from a reliable source like the National Oceanic and Atmospheric Administration (NOAA), National Park Service records, or source acceptable to Contracting Officer" and names no station or threshold. The offeror interprets NOAA 1991–2020 climate normals for Jacksonville International Airport (station USW00013889), counting each day with

0.50 inch or more of precipitation as a non-working weather day, as the basis for the Factor 2 schedule and the Weather Calendar. Is that basis acceptable to the Contracting Officer?

Yes

Appendix C §1.a states that sheet pile installation, riprap scour protection and spartina planting "shall only be conducted during low tide conditions when the substrate is fully exposed," Amendment 0004 RFI #61 states "Low tide requirement is limited to work below (waterward) the High Tide line," and Sheet G0.1 Design Criteria note 5 gives project tidal elevations for NOAA "TIDAL STATION ID 872-0186." The offeror interprets the §1.a condition as met at a given work location below the high tide line whenever the water surface is below the substrate elevation at that location, read against station 872- 0186 and the existing grades on Sheets S3.1, S3.2 and C3.1. Is that interpretation correct?

Your interpretation is correct. Low tide work condition requirement only applicable to the works at waterward side of high tide line.

Appendix C §1.a states that sheet pile installation, riprap scour protection and spartina planting "shall only be conducted during low tide conditions when the substrate is fully exposed." Amendment 0004 RFI #62 asked whether days lost to tide, weather or wildlife stop-work are "excusable time," and the Government responded "Excusable delay with no cost to government." The offeror interprets that response as entitling the Contractor to an extension of the contract time, without liquidated damages, for each workday on which the Appendix C §1.a low-tide condition prevents scheduled work below the high tide line. Will the Government extend the contract time for each workday on which the Appendix C §1.a low-tide condition prevents scheduled work below the high tide line?

Yes, at no cost to government

Section 01 11 00 para. 1.12.A states "Geotechnical Engineering Report, prepared by AECOM is available with Appendix A of this package," and Appendix A is an AECOM Draft Submittal dated June 14, 2024; Section 31 23 00 para. 1.2.O lists a "Geotechnical Report by TERRACON, April 2024"; and Sheets C1.5, C6.1 and C6.2 note 1 state "REFER

TO AECOM GEOTECHNICAL REPORT "GEOTECHNICAL ENGINEERING REPORT" DATED

APRIL 14TH 2025." Neither the April 14, 2025 report nor a Terracon report is in the solicitation; Appendix A states that "Terracon Consultants, Inc. from Jacksonville, Florida drilled the borings" in April 2024. The offeror interprets the April 14, 2025 AECOM report as the geotechnical report the drawings rely on. Will the Government issue the April 14, 2025 AECOM Geotechnical Engineering Report by amendment as the report referred to in Section 01 11 00 para. 1.12?

The geotechnical field work was done by Terracon Consultant Inc and engineering report was prepared by the AECOM. The design is based on AECOM Geotechnical Engineering report dated June 14, 2024 as attached with Division 1 Specification under Appendix A.

Section 31 37 16 para. 1.5.C.1 requires the Contractor to "Secure NPS approval of source before mobilization," and para. 1.3.A requires product data including "Material source, gradation curves, test reports, quarry certification." The offeror interprets the specification as permitting the riprap source submittal under para. 1.3.A to be made after contract award and before the Notice to Proceed that starts the 259-calendar-day period. Is that interpretation correct?

The contractor shall submit material source, gradation curve, test reports, quarry certification etc. prior to procurement and site delivery of riprap stones and NOT prior to Contractor's site mobilization after NTP.

Section 31 37 16 para. 1.5.C.1 requires the Contractor to "Secure NPS approval of source before mobilization," while Section 01 31 00 para. 1.4.D, "Division 1 submittals required prior to mobilization," does not list riprap source approval, and riprap is not placed until after Phase 1 pile driving. The offeror interprets para. 1.5.C.1 as requiring source approval before riprap or bedding stone is delivered to the site, not before mobilization. May the Contractor mobilize and begin Phase 1 work before the riprap source is approved, provided no riprap or bedding stone is delivered until NPS approves the source?

Please refer response to question #85.

Section 01 57 19.12 para. 3.1.B.1 limits impact noise at 50 feet to 70 dB(A) for "More than 12 minutes in any hour" and 80 dB(A) for "More than 3 minutes in any hour," para.

3.1.B.2 lists "Pile Drivers" at 95 dB(A) at 50 feet, and Section 31 41 16.16 para. 3.6.B states "Determine appropriate noise limits in accordance with U.S. Occupation Safety and Health Administration guidelines." The offeror interprets the 95 dB(A)-at-50-feet limit in para. 3.1.B.2 as the noise limit that applies to sheet pile driving under Section 31 41 16.16 para. 3.6. Is that interpretation correct?

Yes, the maximum permissible construction equipment noise level for pile drivers shall be 95 dB(A) at 50 feet. The contractor is responsible for properly selecting the means and methods and equipment to work within the noise limits

Section 31 41 16.16 para. 3.2.E.2 states "Use cast steel shoe to prevent damage to the tip of the sheet piling," and para. 1.3.A.2.c lists "Pile Shoe" as an "A" shop drawing. The sheet piles on the drawings are SG 750 PVC and UC-95 FRP sections. The offeror interprets para. 3.2.E.2 as satisfied by the tip protection the sheet pile manufacturer recommends for those sections, submitted under para. 1.3.A.2.c. Is that interpretation correct?

Yes, the interpretation is correct.

Section 31 41 16.16 para. 3.5.B states "The vibration during the pile driving activities must be limited to a peak particle velocity American Association of State Highway and Transportation Officials (AASHTO) guidelines" without stating a value, and Amendment 0002 RFI #35 requires monitors "one at Visitor Center and other at Planter's House."

What peak particle velocity limit, in inches per second, will be enforced at each of the two monitors?

The peak particle velocity limit of 0.1 inches/second to be enforced as specified in AASHTO for Historical Site or Other Critical Location.

Section 31 41 16.16 para. 3.2.J requires an as-driven survey after each pile group and states "Do not proceed with placing other attachments until the Contracting Officer has reviewed the survey," para. 1.3.A.2.b lists the As-Driven Survey as an "A" submittal, Section 01 33 23 para. 1.3.D.1.a states "Allow 30 days for initial review of each submittal," and para. 3.2.D states "Partial submittals are not acceptable." The offeror interprets each pile-group as-driven survey as a complete submittal that the Contracting Officer will review within 5 calendar days so that wales, caps and tie rods (Sheet S3.1 step 7; Sheet S3.2 step 2) may proceed. Within how many calendar days of submittal will the Contracting Officer complete review of each as-driven survey?

Allow 5 working days for review each pile group as-driven survey by the Contracting Officer.

Appendix C §4 states "Species that require specific attention along with measures for their protection shall be listed in the Contractor's Environmental Protection Plan prior to the beginning of construction operation." No Environmental Protection Plan appears in the Division 1 submittals required prior to mobilization in Section 01 31 00 para. 1.4.D or in the action and informational submittal lists in Section 01 33 23 paras. 2.1 and 2.2.

The offeror interprets the Environmental Protection Plan as an action submittal to be approved before mobilization with the Division 1 submittals. Does the Environmental Protection Plan require Government approval before mobilization?

Yes

Amendment 0004 RFI #63 states "It is estimated that maximum three (3) ceder trees to be removed at the entrance of the temporary access road to construct the road" and "One Ceder tree near to the existing wall (refer Drawing S1.1) to be replaced with minimum 10 years old same species tree," while Sheet G0.1 Tree Replacement note 1 requires the Contractor to "REMOVE EXISTING CEDAR TREE AND REPLACE WITH A NURSERY-GROWN CEDAR TREE OF SIMILAR SPECIES." The offeror interprets the replacement requirement as applying only to the one cedar near the existing wall, and not to the cedars removed at the entrance of the temporary access road. Is that interpretation correct?

Yes, the interpretation is correct. The contractor shall coordinate with the Contracting Officer prior to removing ceder trees at the entrance of the temporary access road.

Appendix C §4.e.i requires the Contractor to "Maintain a distance of at least 500 feet from any roosting, flocking, or foraging, shorebirds," and §4.e.ii states "All construction activities should cease if any Red knots are observed within 50 feet of the operation."

Appendix C §4.e states that red knots "may be present along the project intertidal areas while migrating through the project area in April-May and September-December." The offeror interprets §4.e.ii as the stop-work requirement under §4.e, with §4.e.i applying to red knots during April–May and September–December. Does §4.e.i require construction to stop whenever shorebirds other than red knots are within 500 feet of the work?

The interpretation is correct given the difficulty to distinguish the red knot from other similar shorebirds. After futher consideration of the location and sight distances, Appendix C has been revised as follows: "Maintain a distance of at least 50 feet from any roosting, flocking, or foraging, shorebirds (small to medium size) on the park side of the Fort George River." and an identification key has been added as reflected in Amendment 6 with this response.

Appendix C §4.f.vii states that "a 10 or Fewer Burrows Permit must be secured" if work will occur within 25 feet of a burrow entrance, Amendment 0002 RFI #38 places the permit on the Contractor, and Amendment 0004 RFI #64 states "The gopher tortoise to be relocated within the park"; the Florida Fish and Wildlife Conservation Commission lists only the property owner or its designated developer as permittee for that permit.

The offeror interprets NPS, as property owner, as the party that must designate the Contractor and furnish ownership documentation for the application. Will NPS designate the Contractor as its developer and furnish the ownership documentation for the FWC application within 10 days of the Contractor's request?

Yes, NPS will designate the contractor and provide documentation of NPS fee-simple ownership to the contractor.

Appendix C Enclosure 3 states "At least 30 days prior to any land disturbance activities, the project proponent shall notify the appropriate USFWS Field Office," and NWP SAJ- 2000-03466 Special Condition 5 states the "Permittee shall comply with U.S. Fish and Wildlife Service's ‘Standard Protection Measures for the Eastern Indigo Snake.’" The NWP verification is addressed to the National Park Service as Permittee. The offeror interprets NPS as the project proponent under Enclosure 3 and the notice as NPS's to send and will schedule land disturbance within 10 days of the Notice to Proceed that starts the 259-calendar-day period on that basis. Will NPS send the Enclosure 3 e-mail notice to the USFWS Florida Field Office at least 30 days before that Notice to Proceed?

Yes, NPS will send the Enclosure 3 e-mail notice to the USFWS field office.

Appendix C Enclosure 3 requires that "the project proponent shall notify the appropriate USFWS Field Office" at least 30 days before land disturbance, and Section 01 31 00 para. 1.9.A.2 states "Construction Contractor will not be considered an agent of the Government." Amendment 0004 RFI #64 states "A limited NTP can be provided to start the permit application." If NPS does not send the Enclosure 3 notice before the Notice to Proceed that starts the 259-calendar-day period, may the Contractor send the notice on NPS's behalf after contract award and before that Notice to Proceed so that the 30-day period expires before land disturbance begins?

NPS will send the Enclosure 3 e-mail notice to the USFWS field office.

Appendix C §1.d, as revised by Amendment 0004, requires compliance with JAXBO general project design criteria "AP1, AP2, AP6, AP7, AP8, AP9, AP11 (General PDCs)" and does not list AP.10, while NWP SAJ-2000-03466 Special Condition 6 requires the work to be "constructed and operated in accordance with all applicable project design criteria" in the JAXBO, and AP.10(a), reproduced in Appendix C Enclosure 4, requires the Permittee to "Install floating turbidity barriers with weighted skirts that extend to within 1 ft of the bottom around all work areas that are in, or adjacent to, surface waters," and AP.10 states that the curtains "may be waived by the USACE project manager." The offeror interprets NWP Special Condition 6 as requiring AP.10 turbidity barriers unless the USACE project manager waives them. Are floating turbidity barriers under JAXBO PDC AP.10 required for this work?

Floating turbidity curtains are not required. If the contractor chose to use floating turbidity curtain, they shall comply with AP.10.

The low tide requirement in Attachment 15 (Appendix C, Section 1.a, revised 10/27/2026) and Amendment 0004 is not defined. Please answer the following before proposals are due on November 13, 2026. (Q98-Q103)

What exactly is "low tide"? Is it a time window around predicted low tide (for example, 2 hours before to 2 hours after), a tide elevation (NAVD88 or MLW), or only when the substrate is physically exposed? Wind can hold water in, so even at predicted low tide the bottom may not be exposed. Who decides on a given day whether conditions are met? Who pays?

The construction components which are waterside of high tide line shall be executed when the substrate is fully exposed. For an example average contour line for the new wall infront of the existing wall is +0.00 NAVD88, so this wall shall be constructed when the tide level is less than +0.00 NAVD88. Refer Appendix C, Section 1.a.

Which tide station and predictions govern (for example, NOAA station 8720186)? There is about 5 feet of tide. How high above MLW can you work?

Refer drawing #G0.1, General Notes, Design Criteria Note #5 for tide station and response to question # 98 for work limit.

100 May pile driving continue as water returns, if a turbidity curtain and/or protective stone is in place and protected species monitoring continues?

Driving pile when water returns is not acceptable per environmental design and installation criteria. It can be only driven when the substrate is fully exposed, refer response to question #98.

Please confirm which/any upland portions of the alignment have no tide restriction.

Refer to USACE permit SAJ 2000-03466 NWP13/NWP 54 Project Drawings 4 to7 of 11 which depict the location of the high tide line (Blue line symbol). The tide restriction is limited to sheet pile driving, riprap installation and spartina planting waterward of this high tide line.

With work limited to 8 AM to 5 PM Monday through Friday, the usable low tide window is often only a few hours, moves every day, and some days never falls within work hours at all. This pushes installation well past 259 days. Will the Government extend the performance period to account for this restriction? If not, how will the schedule be evaluated?

Period of Performance extensions will be discussed when and if delays occur after award of the project.

Can the sequence of construction be changed to better match the workers' schedules?

Project should be bid in accordance with Specification 01 11 00 1.3. Value engineering proposals may be discussed following contract award.
