PRE-PROPOSAL QUESTIONS & ANSWERS

JFY 2022 PROJECT J-875, BATTLE STAFF TRAINING FACILITY,

U.S. NAVSUPPACT MCB CAMP BLAZ, GUAM

NOTE: The following questions and answers are provided for INFORMATION ONLY. The

RFP remains unchanged unless it is amended in writing on a Standard Form 30.

REVISED RESPONSES FROM NOTICE NO. 4:

80. Reference: Solicitation-N6274226R1306 Section 01 45 00 1.6.7.1 CQC Geotechnical

Specialist

The specifications require that the Cement Density Soil Mixing (CDSM) observer be a GTQC professional (10 years licensed with 8 years of geotechnical engineering practice) and have a minimum of five (5) years of relevant CDSM inspection experience.

A 10-year licensed engineer with 8 years of geotechnical experience would likely not have 5 years of CDSM inspection experience, unless they are an employee of a CDSM installation contractor. Most registered engineers professionals with 8+ years of geotechnical experience would be working on a variety of geotechnical projects as technical or management leads.

Please confirm whether a qualified geotechnical field representative may perform day-to-day

CDSM observation under the supervision and direction of the designated GTQC professional, with the GTQC maintaining responsible charge, oversight during critical points of CDSM construction, and daily review of the work.

Additionally, please advise if there are any specific requirements regarding documentation, supervision level, or reporting structure for this arrangement to be considered compliant with the specifications.

ANSWER: Bid as advertised. Note that per Specifications 31 62 00, Para. 1.8.1, the Contractor's

QC Geotechnical Specialist shall be onsite full-time only during the field verification program to observe and document the CDSM test column construction/installation and associated verification testing (e.g. observe/log cores). The day-to-day CDSM observation can be performed by the Contractor's Geotechnical Field Representative under the supervision and direction of the Contractor's QC Geotechnical Specialist. Section 31 62 00, 1.7.1 allows for the production CDSM columns to be observed by competent and qualified personnel to continuously observe and record the required data. For other specific requirements related to CDSM, refer to specifications 31 62 00.

81. Kindly request a four-week extension to the bid submission date for this solicitation.

ANSWER: The proposal due date will be extended to July 7, 2026 in a forthcoming amendment.

NOTICE NO. 5:

82. We would like to respectfully request a three (3) week extension for the bid submission deadline from June 23, as we are experiencing difficulties obtaining pricing from suppliers and our subcontractors for long-lead items.

This additional time would allow us to gather the necessary information and submit a complete and competitive proposal.

ANSWER: Please refer to response to Q81.

83. Sheet A-610, Interior Color and Material Schedule, designation RAF-2, specifies “Concore

All Steel Access Floor Panels with Factory Installed Carpet Posi-Tile – Shaw Contract, Noble

Materials, Alchemy Tile 5T135, Cornerstone Copper 33555. The Posi-Tile is proprietary to Tate

Access Floors and will exclude all other U.S. manufacturers from bidding this project. Please remove the Posi-Tile requirement for a peel and stick adhesive to bond the carpet tile to the raised floor panel. This will remove any telegraphing of the Posi-Tile button through the carpet tile.

ANSWER: Please refer to General Sheet Note #4 on Sheet A-610.

84. Sheet A-TN111 calls for 24” and 30” cable trays underneath the raised floor. Spacing between pedestals will be less than 24. There will be between a 1.5” to 3” reduction of space from centerline of the pedestal shaft to the next, depending on the pedestal type prescribed by the seismic calculations. Can the cable tray widths be reduced to 20-inches wide to keep them between the pedestals?

ANSWER: Raised Access Floor (RAF) pedestals are typically installed first and are fixed at

24”x24” spacing. In coordinating the cable tray layout per Section 27 10 00 paragraph 1.6.1 and

2.3, where the Contractor finds that a conflict between the cable trays and RAF pedestals is unavoidable, the wire mesh basket cable trays can be cut or altered to accommodate the RAF pedestal spacing. This is preferred to providing parallel or vertically-stacked cable trays, because this approach keeps the cable bundles organized, going in the same path at the same elevations, and eventually able to line up to the Cabinets in the Telecom Rooms.

175-PSI CDSM is approximately 8,168 cubic yards. However, Bid Item No. 0001AC on the Bid

Form (SF 1442) identifies the quantity of CDSM as 7,920 cubic yards.

Please clarify which quantity shall govern for bidding purposes:

a. Shall bidders base their pricing on the quantity of 7,920 CY shown in Bid Item No. 0001AC of the SF 1442?

b. If the quantity derived from the drawings (approximately 8,168 CY) is intended, will the

Government issue a revision to the bid schedule?

c. In the event of a discrepancy between the drawings and the bid form, please identify the governing quantity for bid preparation.

135. Extension

Given that Notice 3 indicates a forthcoming amendment extending the proposal due date to June

23, 2026, we respectfully request an additional four week extension beyond June 23 to allow adequate time for a complete and accurate proposal.

Our material vendors and suppliers have informed us that, due to current workload and manufacturer response times, they require an additional 20 days to solicit and receive material and equipment pricing. This extended lead time directly impacts our ability to prepare accurate cost proposals, particularly for long lead and specialty items.

In addition, there is currently over $1 billion in NAVFAC Pacific work concurrently out for bid, all due within the same general timeframe. Guam’s limited pool of qualified prime contractors and small business subcontractors further constrains industry capacity during periods of high solicitation volume. The combination of simultaneous major procurements, restricted subcontractor availability, and extended vendor pricing lead times significantly increases the time required to thoroughly review the drawings, specifications, and Government responses to

RFIs.

A four week extension beyond the June 23 deadline will provide contractors, including small business subcontractors, the necessary time to obtain accurate vendor pricing, assess the solicitation requirements, coordinate subcontractor proposals, and prepare a fully compliant and competitive submission.

ANSWER: Please refer to response to Q81.

136. I am currently working on the OSP fiber runs and see on drawing TN601 there is reference to ADF1 and ADF 2. I need to know where those are to calculate distance but don’t see them geographically on any site plans. Can you please assist?

137. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 1.7.1.2.b and

Paragraph 2.2.2

Intent and Necessity of Predrilling Requirements

Paragraph 1.7.1.2.b outlines tracking requirements for predrilling, including diameter and backfill material. Because the fundamental methodology of CDSM relies on mechanically blending the native, in-situ soil with cement grout, predrilling is not typically performed during standard production as it removes or disturbs the required soil matrix. Please clarify the

Government's intent regarding these requirements and purpose of predrilling. Is predrilling intended to be limited strictly to bypassing localized hard strata/obstructions, and if so, what approved backfill materials are expected if the native soil matrix is removed prior to mixing? If predrilling and CDSM happen concurrently, will multiple GTQC specialist personnel be required onsite to monitor both predrilling and CDSM activities.

138. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraphs 1.7.1.2.e, 1.7.1.2.i

(Items 8 and 10), and 1.7.1.2.j

Real-Time Field QC Monitoring Capabilities vs. Next-Day Rig Telemetry

Paragraphs 1.7.1.2.e and 1.7.1.2.i require real-time monitoring and reporting of specialized metrics like torque data and continuous cement content. Based on typical CDSM methodology and local project experience, manual field observation by the GTQC or Geotechnical field representative is limited to tracking grout quantity, pressure, depth, flow rate, and rotations at regular intervals in real time. Advanced mechanical telemetry, including torque and high-resolution depth profiles, is captured automatically by the rig's data acquisition system and compiled the next day. The GTQC can obtain this information in real-time by having personnel on the rig, which poses safety concerns, or having remote viewing capabilities of the operator’s screen, which leads to additional complexities with technology that can cause delays if the relay is disrupted due to poor connectivity. Please clarify if the Government will accept manual field logs focused on operational parameters per CDSM column, supplemented by the specialty contractor’s automated digital rig outputs provided separately, as has been accepted for previous projects.

139. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 3.2.1

Execution and Verification of Strict Real-Time Alignment Tolerances

Paragraph 3.2.1 outlines rigid horizontal and vertical alignment limits. Because down-hole deviation is difficult to track accurately, please confirm if initial surface layout validation by a surveyor satisfies the horizontal requirements, and clarify the detailed requirements in submitting vertical alignment profiles that are acceptable to the Government for verticality compliance.

140. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 3.4.1.3

Method Requirements for Vertical Alignment Profiles

Paragraph 3.4.1.3 requires the submission of daily 'vertical alignment profiles' per machine.

Because specific execution methods are not detailed, please clarify the approved or preferred testing methodology, instrumentation, or industry standard expected to satisfy this profile requirement.

141. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 3.1.e

Core Drilling Location Relative to Column Diameter

Paragraph 3.1.e of Section 31 62 00 requires that verification coring be conducted approximately

3 feet from the center of the CDSM column; however, contract drawing SB101 designates the

CDSM columns as 4 feet in diameter (2-foot radius). Coring at a 3-foot offset could result in drilling outside the treated soil area. Please clarify the offset distance from the center of the column to ensure representative core samples are captured within the treated zone.

142. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 3.2

Schedule Impact of the 60-Day Curing and Fill Restriction

Paragraph 3.2 imposes a 60-day calendar restriction against placing more than 5 feet of fill or 4 psi of vertical pressure within 26 feet of installed CDSM columns. Given that the specified design strength of 1,200 kPa (175 psi) is explicitly based on 28-day curing breaks, please clarify if this 60-day restriction can be waived or shortened for localized zones once 28-day laboratory break results demonstrate that the target unconfined compressive strength has been achieved.

143. Reference: Solicitation-N6274226R1306 Section 31 62 00, Paragraph 1.4.1.f and Paragraph

1.4.2

Commercial Bidding Risk Regarding Post-Bid Design Changes from Probing/Grouting

Paragraph 1.4.1.f notes that baseline CDSM quantities, locations, and tip elevations are completely subject to change following post-bid probing and grouting operations. Because pricing specialized ground improvement heavily relies on definitive structural layouts and fixed material volumes, this fluid language prevents bidders from establishing accurate and fair estimates. Please clarify the Government's contingency plan if the results of the probe-and-grout activities cause substantial changes to the design plan. Additionally, will the Government establish a fixed baseline quantity schedule for bidding purposes, and confirm that major post-bid structural or layout redesigns will be handled through adjustment change orders?

Definition of "Real-Time" Structural Movement Monitoring

This paragraph states: "Establish temporary benchmarks... along new and existing structures within 10 feet to the CDSM soil improvement area. Monitor the benchmarks real time during the

CDSM soil improvement operation to detect any settlement, uplift, or lateral movement... If movement in excess of 1/2 inches... is detected, all CDSM work shall immediately cease."

Paragraph 1.10.1 requires 'real-time' benchmark monitoring of structures within 10 feet of the work area to guard against a 1/2-inch movement threshold. Please clarify the Government's expectation for the term 'real-time.' Will the Government require an Automated Motorized Total

Station (AMTS) system for continuous data streaming, or are manual survey checks at prescribed production intervals (e.g., beginning, midpoint, and end of shift) acceptable?

147. Reference: Solicitation-N6274226R1306 Section 01 45 00, 1.6.7.1 CQC Geotechnical

Specialist

Additional Clarification on Qualifications of Geotechnical QC Specialist:

The specifications require that the Cement Deep Soil Mixing (CDSM) observer be a GTQC

Professional with a minimum of 10 years of licensure, 8 years of geotechnical engineering experience, and at least five (5) years of relevant CDSM inspection experience.

Would NAVFAC consider an alternative staffing approach whereby day-to-day CDSM observation activities are performed by a qualified degreed engineer or geologist (EIT, GIT, PE, or PG) with a minimum of 2 years of experience under the supervision and direction of the designated GTQC Professional? Under this approach, the GTQC Professional would maintain responsible charge, provide oversight during critical phases of construction, conduct periodic site visits, and perform a daily review of observation records and construction activities.

We respectfully note that the requirement for five years of dedicated CDSM inspection experience may significantly limit the available pool of qualified personnel. In practice, many experienced geotechnical engineers develop expertise across a broad range of ground improvement, deep foundation, earthwork, and specialty geotechnical construction projects rather than concentrating exclusively on CDSM observation. As a result, highly qualified geotechnical professionals with extensive quality control and construction observation experience, including recent CDSM experience and familiarity with local conditions, may not satisfy the specific five-year CDSM experience threshold despite possessing the technical knowledge and judgment necessary to effectively oversee the work.

Accordingly, we request consideration of a GTQC Professional who is a licensed Professional

Engineer with relevant and recent CDSM experience, including experience with CDSM projects performed on Guam, supported by qualified field personnel operating under their supervision and responsible charge.

ANSWER: See response to Q80.
