1 Electrical Because this facility is owned by the

United States Federal Government, and is utilized as a Maintenance Utility

Building, we understand that Unified

Facilities Criteria (“UFC”) 3-520-01 and

Unified Facilities Guide Specifications

(UFGS) Section 26 05 19.10.10 shall apply for purposes of competitive bidding and project execution. To ensure that the project is bid and constructed in accordance with the applicable regulations and requirements, please confirm that UFC 3-520-01 and

UFGS Section 26 05 19.10.10 shall apply to this project. Specifically, please confirm that bidders are permitted to utilize the type(s) of material(s) described in UFC 3-520-01 and UFGS

Section 26 05 19.10.10 applicable to their scope of work despite any potentially contradictory provisions in the design plans and specifications.

As a federal project, all Department of

Defense UFC standards are applicable. Applicable UFGS specifications are included in the project technical specification sections, edited to project requirements. Reference the applicable technical specifications for requirements.

2 Electrical Regarding the Build America Buy

America Act (“BABA”), please confirm the products in this design and that are specified comply with all BABA requirements or otherwise please:

1. Identify any and all General

Applicability Waivers related to any products, categories of products or manufactured products specified for this project.

2. Name any and all project level waivers that have been proposed and/or awarded for this project.

Project is designed to comply with the

Buy American Act.

3 Given the complexity of this project and the level of effort required to prepare a comprehensive effort and proposal, we request that the proposal due date be extended to May 15, 2026. This will afford Contractors the time needed to provide the Government with comprehensive, cost efficient proposals.

See Amendment for due date extension.

4 Salvage disposition list, which items are assumed required and at what point during the project will the Government

Refer to AD101 for salvaged material.

Awardee shall submit post award RFI.

Contracting officer issue disposition for salvaged materials?

5 S-002 Pre-engineering metal building ,"Metal framed building, States the metal building manufacturer must provide supplemental framing to support the required building systems and equipment loads at no additional cost to owner."

Government to provide values for all equipment loads to be supported.

Contractor shall provide equipment loads based on selected manufacturer.

6 Please explicitly define the scope of the engineering requirements for the cold form metal framing

The Engineer delegates the design of the pre-engineered metal building

(PEMB) to the metal building manufacturer (MBM). The MBM will submit the design drawings and calculations to the Engineer I9:I213 for final review and approval after the

MBM has had the drawings and calculations stamped by a third-party licensed engineer.

7 S-101 Government to provide information related to size, depth, and installation date of existing duct banks shown on S-

101. Government to confirm existing ductbank conditions will be acceptable with proximity of pile installation efforts.

Location of ductbank was identified within design. Keynote #1 on S-104 indicates that the GC will need to field-verify the extents of the duct banks prior to pile installation and construction.

8 If specific manufacturers were used in space planning, design coordination and design of the building structure, please provide the information from the manufacturers that was incorporated into the building design. Please confirm design flexibility was incorporated to account for all approved manufacturers in the case an approved manufacturer is procured in lieu of the BOD.

Confirmed. Design flexibility was incorporated and no basis of design manufacture was required.

9 Will contaminated soils, classified as non-hazardous soil for disposal by spec definition be the responsibility of the contractor if discovered after bidding during soil classification testing?

Contaminated soils require increased

PPE controls and have special disposal restrictions as mandated by PNSY which will increase cost. How should bidders quantify this unforeseen increase?

The Contractor will need to dispose of all soils in accordance with the

Specifications in the RFP. The

Contractor should assume any soil determined 'contaminated' by the disposal facilities should be priced as hazardous soil for the purposes of bidding.

10 Confirm if any dust cleaning of the building surfaces will be necessary to remove hazardous dust prior to construction. E.g. lead, ACM, guano, pcb, etc.

Refer to RFP Specification Sections

02 82 00.00 22 and 02 83 00.00 22

The BWRO treats SWRO permeate only and does not require seawater process design. However, as the units are located in a coastal/marine environment, materials must be suitable for external salt exposure.

Standard galvanized components and carbon steel fasteners are acceptable provided they have proven service experience in similar coastal

SWRO/BWRO installations and corrosive water will not be in contact with the galvanized components.

Duplex 2205 or Nylon materials are typically utilized and recommended.

NSF 61 certification/compliance is not required for this project. For piping and components upstream of the BWRO, the use of Duplex 2205 stainless steel or approved Nylon materials is acceptable and recommended due to enhanced corrosion resistance in brackish water environments. 316 stainless steel shall not be used in these locations.

74 D-106 UF Drain Pumps Common Discharge

Magmeter: Please consider installing a magmeter on the common line of the UF

Drain Pump Discharge for pump protection and drain control.

Due to limited space, a meter will not be installed on the UF drain pump pipe. A meter (07-FIT01-001) is installed on the 12" common outfall pipe.

75 D-404 Air Ejector System: Air ejector panels will be supplied for the UF membrane trains but are not shown on the drawings.

79 Given the size, complexity, and technical requirements of this procurement, we requested a bid extension to May 21.

This additional time would support more complete and competitive proposals that provide best value to the NAVFAC.

Currently other ongoing NAVFAC procurements are the main focus of other vendors, and extending the bid date will provide for better vendor coverage and thus help ensure the best possible price for NAVFAC.
