Z2DZ--Modernize Generator Project

Questions & Answers / Clarifications

This document contains responses to Requests for Information (RFIs) related to a solicitation for generator system upgrades and related work at various buildings (B30, B32A, T-1 East Wing).

• As-Built Certification: As-built information on plans must be certified by a state professional surveyor and mapper; waiver requests for QC Manager confirmation are denied.
• Staging Areas: Specific locations for staging/laydown areas are not confirmed in advance due to ongoing projects. Requirements include temporary fencing, stabilized entrances, BMP measures, and restoration of foliage.
• Chain-Link Fence & Gates: Detailed specifications are provided for fence height, posts, fabric (material, mesh size, coating, color), framework finish, and gates, including hardware and concrete footing requirements.
• Fire Alarm Connection: No fire alarm connection is required for the new fire damper at the Building 30 Generator Room; dampers are thermally-actuated and controlled by the engine generator system.
• Fiber Optic Cable: Existing 3" conduit can be used for new fiber optic cable. Coordination and supervision by a 3rd party (e.g., AT&T) will be managed by the VA. The contractor will be responsible for executing and managing contracts with third-party providers.
• Temporary Generator Fuel: Assume enough fuel reserve to refill each tank once; continuous refueling is not permitted; a temporary fuel tank meeting specifications is required.
• Period of Performance: An increase from 240 to 630 calendar days is requested due to generator lead times; this will be discussed post-award.
• Hazmat Survey: The Hazmat/Asbestos Survey report is the contractor's responsibility.
• Utility Corridor: No as-built drawings for the E-Wing utility corridor are available; contractors must field-verify conditions.
• Fuel Disposal: The contractor is responsible for the disposal of fuel from existing generators prior to demolition.
• Factory Tests: Standard unity power testing is allowed for both factory and on-site tests.
• Paralleled Operation: Paralleled operation is NOT specified for B30 generators.
• Lube Oil Heater: Lube oil heaters are not required for the Hawaii climate.
• Starting Batteries: NiCAD starting batteries are required; substitution with sealed lead acid is not an approved equal.
• Spare Parts: Specific quantities of spare filters (lubricating oil, primary fuel oil, secondary fuel oil, intake air) and fuses are required per generator.
• Seismic Isolators: Factory-recommended IBC seismic-certified integral isolators are acceptable as an alternate to spring-type isolators upon review and approval.
• Switchboard Voltage: Clarification provided that the switchboard voltage should be 480V, not 208V as initially stated.
• Branch Breakers: New circuit breakers are required for all circuits to remain.
• Load Bank Breaker: A dedicated 1200A load bank connection enclosure with an integrated breaker is the intended approach.
• Parking Lot Access: Director's parking stalls will not be used by staff during construction; daycare drop-off/pickup will remain active.
• Modbus Connection: New generators require Modbus RTU or Modbus TCP/IP communication interface for BAS integration.
• Fuel Tank Monitoring: Existing Veeder Root probes and leak sensors will be demolished and replaced with new sensors. Equivalency for Veeder Root or other brands may be submitted for review.
• Double Wall Piping: Double wall piping is required for exterior locations and cannot be deleted.
• Day Tank Emergency Vents: Day tank and belly tank vent piping shall be routed to the exterior, with existing vent piping intended for reuse.
• Fuel Fill Station: Standard painted steel construction is acceptable for the Building 32A fuel fill station.
• Bldg 30 Retrofit: The intent is to replace the switchboard bus and all breakers, adding a new 1200A breaker for the load bank in a separate/adjacent apparatus.
• Confined Spaces: Utility corridors at E-Wing and MH-7C are considered confined spaces.
• Fiber Optic Route: Existing underground conduits and vaults will be utilized for the DDC fiber optic route.
• Submittals: The COR will oversee all submittals, with some requiring A/E review prior.
• Equipment Packages: Equipment packages are Contractor-Furnished, Contractor-Installed (CFCI). The VA does not mandate national account vendors.
• CQC Manager: Requirement for a graduate engineer, architect, or construction management degree AND 5 years of field experience is confirmed.
• Bid Due Date: The bid due date has been extended to Friday, 5/22/2026, 12 PM HST.

This document provides critical clarifications and details that bidders must consider when preparing their proposals, affecting specifications, materials, installation methods, and timelines.

Form / Attachment / Pricing Sheet

This document is a Standard Operating Procedure (SOP) titled "Contractor Operations and Storage Area (COSA) Request Instructions." It outlines the procedures for contractors to request and manage COSA sites on Army Installations of Hawaii (USAG-HI). The SOP details the purpose, applicability, scope, general requirements, responsibilities, COSA period, and procedures for requesting, approving, and closing out a COSA.

• Purpose: To promote efficient use of land resources by providing procedures for initiating, coordinating, scheduling, and managing COSA sites.
• Applicability: Applies to all Army construction contracts requiring a COSA, including MILCON, R&M, and SRM projects, for sites outside approved "project boundaries."
• Process: Involves submitting a Facilities Engineering Work Request (FEWR) and a COSA Request (Enclosure 1), which includes details on site location, items stored, parking, utilities, and potential environmental impacts.
• Processing Time: Minimum COSA processing time is 14 calendar days.
• Submission Timeline: Requests should be submitted no later than 8 weeks prior to occupation.
• Contractor Responsibilities: Includes providing a 90-day notice to vacate, site restoration, and maintaining good stewardship.
• Key Contacts: Lists POCs within various Directorate of Public Works (DPW) divisions (Engineering, Planning, Environmental) and other relevant agencies.

This document is crucial for any contractor awarded a construction contract on USAG-HI that requires the use of a Contractor Operations and Storage Area. Bidders must understand the COSA request process, timelines, and responsibilities to ensure compliance and successful project execution. It details what information is required for a COSA request, who to contact, and the steps involved from initial request to final closeout. Failure to adhere to these procedures could impact project schedules and operations.
