Existing conduit sleeves, reaceways, or cable trays may be reused as long as conduit fill is in accordance with NFPA 70. Existing wiring to remain until the new system is fully comissioned/accepted.

JDW

FIRE ALARM SYSTEM

Use of raised floor plenums – In the areas with raised floors, are we permitted to run fire alarm cabling beneath the floor or within the ducted cavities? Are the hatches large enough for access, and will we need to remove floor tiles or coordinate with IT/operations staff to access cables?

Fire alarm cabling may only be routed beneath raised floor for devices located in raised floor. Wiring serving all other devices to be routed above ceiling. JDW

FIRE ALARM SYSTEM

Ceiling construction and mounting heights – For each area, please clarify the ceiling type (lay in acoustical tile, gypsum board, hard lid, open structure) and the approximate height so we can determine lift/scaffolding requirements and estimate conductor runs. We observed drop ceiling heights of 8′, 10′, 12′, and 15′ during the walk through.

All available fire alarm and architectural as-builts were made accessible during the pre-proposal site visit and on a subsequest date during the following week.

GENERAL

Work area accessibility – Are there restricted zones requiring escorts (e.g., data centers, secure storage, IRS operations)? Will escorts be available during normal work hours, and how must we schedule access? Are there times when work in specific areas is prohibited due to mission critical operations or tax payer data processing?

Yes, there are restricted areas (Data Center J & K modules, Childcare E Module). Proper scheduling and coordination needed for secured area access. Escorts will be available witth prior planning and coordination. IRS

GENERAL

Temporary facilities – We understand that the Design Builder may not use existing restrooms or dumpsters and must provide portable toilets and waste containers. Can we locate these near the laydown area? Are there any restrictions on bringing water or power onto the site for temporary trailers or equipment?

Dumpsters/Porta potties can be stationed at the staging area. There are no restrictions for bringing water and power onsite.

IRS

GENERAL

Proper scheduling is necessary for the relocation of employees during overhead work.

Employees will be moved during overhead work. A schedule of work should be provided at the beginning of the project to provide adequate time for coordination. IRS

FIRE ALARM SYSTEM

Parallel installation – The scope indicates that the new system will be installed in parallel with the existing system until completion. Will we be required to energise and test circuits as they are installed or wait until final cutover? Should we plan for dual devices (existing and new) to remain in place temporarily, and will ceiling tiles need to be removed and reinstalled twice?

Final means/methods for energizing and testing the new system is up to DB contractor. The existing system needs to be maintained in its entirety until the new system is fully comissioned/accepted. Dual devices will be in place until the new system is accepted and demolition can start on the existing system. The GSA FPE will not witness final testing until the entirety of the new system is pretested with appropriate documentation submitted for review.

JDW

FIRE ALARM SYSTEM

Interim monitoring – During the installation phase, who will monitor and respond to alarms from the existing system? Will the new panel need to monitor the old system or vice versa to maintain life safety coverage? Are there concerns about nuisance alarms or cross talk between systems?

Systems should be completely separate with little to no cross talk. The existing system will be monitored by the existing monitoring company.

DB Contractor will be responsible for confirming monitoring capabilities of the new panel (i.e., POTS vs cell vs IP). GSA to provide monitoring service and connection.

JDW

FIRE ALARM SYSTEM

Cutover sequence – How will the final cutover be scheduled? How will testing and acceptance be conducted to minimize disruption to the IRS operations? The quality control section indicates that a complete (100%) final test must be performed and documented; please confirm who must witness each test and whether after hours testing will be required.

This is a full system replacement. The existing and new systems will be installed in parallel so there should not be much, if any, final cutovers required. Final means/methods for testing is up to the DB contractor. As long as the GSA FPE receives proper documentation from the pretest it does not necessarily have to happen concurrently.

JDW

FIRE ALARM SYSTEM

Authority Having Jurisdiction (AHJ) – The documents state that the GSA Region 6 Fire Protection Engineer will serve as the AHJ. Will local Memphis Fire Department officials also review and approve the design, or does GSA approval supersede local jurisdiction? Should the system conform strictly to NFPA 72/70/local codes, or will federal/GSA criteria trump local requirements?

GSA FPE approval will supersede local jurisdiction. Local Memphis Fire Department will be give a courtesy review and will be invited to participate in an on-site walkthrough if requested. Final approval from Memphis FD is not required.

Local requirements above and beyond federal/GSA criteria will be considered on a case by case basis with final determination by GSA FPE.

Are follow up RFIs after 20 Jan allowed, especially if additional information emerges during the escort survey? What is the protocol for questions arising during design that require clarification from the government?

All questions were due on 1-16-26 and a response is provided to each question via this document on 2-2-26. Additional questions after 2-2-26 can be submitted to the CO for consideration by GSA. If the CO determines a response to the question is critical to the solicitation, additional communication will be provided via amendment to the solicitation. RFIs arising during the project will be handled through a predetermined RFI process to be discussed after contract award.

GENERAL

Badging and security clearance – Security and badging can be a lengthy process.

Are background checks required for all subcontractors and vendor personnel on site, and will escorts be needed for the duration or will some badges be issued?

Will work being performed on the exterior of the facility require escorts?

We will cover HSPD12 requirements after contract award. Some personnal can be escorted or the majority will need to have passed a Background Investigation. JAIII

GENERAL

Allowances for after hours work – The noise management paragraph stipulates that work exceeding certain decibel thresholds must occur outside normal working hours. Should we include an allowance for overtime or off hour shifts in our estimate? How should we account for escort overtime and security costs outside the normal 7:00 a.m. – 4:00 p.m. window?

Most work will take place during normal business hours. Some testing and electrical shut downs may occur after hours in which case the contractor will pay the escorting service directly at a rate of $40.76/ hr JAIII

GENERAL

Material storage and staging – Since construction materials must be stored off site or in designated Laydown area, should we include rental costs for off site warehouse space and daily transport? If the government provides temporary storage space inside the building, what is its size and accessibility (freight elevator, loading dock, etc.)?

Materials do not neccesarily need to be stored off site. If the contractor chooses to store materials off site it will be at the cost of said contractor. The lay down area and size of freight elevator, loading dock were discussed and made available during the pre-proposal meeting.

GENERAL

Testing equipment and specialized tools – Will the government furnish any testing apparatus (e.g., calibrated sound level meters for noise monitoring, duct detector test pumps, NFPA 72 acceptance test equipment), or should we include the purchase/rental of such equipment in our estimate?

FIRE ALARM SYSTEM

Device mounting for pendant strobes – We observed pendant mounted strobes approximately 12 inches below the drop ceiling. Is this mounting method preferred for replacements, or will ceiling mounted or wall mounted notification appliances be acceptable? Are there ceiling structural supports or plenum obstructions that dictate pendant drops?

Ceiling/wall mounted are preferred but pendant mounting is acceptable as well in case there are ceiling obstructions that would prohibit a ceiling mount.

JDW

FIRE ALARM SYSTEM

Raised floor detection – For the raised floor areas, is under floor smoke detection required, and if so, must cable be run in metal conduit within the floor? Are there water or data lines in the raised floor that could impede installation or require shielding?

Raised floor areas to be protected based on existing devices.

JDW

FIRE ALARM SYSTEM

Fire alarm panel location – Will the new fire alarm control panel and power supplies be installed in the same room as the existing panel, or will a new equipment room be provided? Are there UPS or generator circuits available for secondary power, or must we include battery back up sized for the full 24 hour stand by and 5 minute alarm operation per NFPA 72?

"Section II.D.(1) requires offerors to submit 3–5 similar projects and defines “similar” as construction or renovation of a fully occupied Government facility or secure civic facility / Class A secured office space (or similar) meeting the following attributes: completed within 10 years, construction cost > $20M, gross square feet > 100K, delivered via Design/Build (or other integrated delivery), and including multiple labor categories (e.g., electrical, HVAC, general construction) We understand and respect the Government’s intent to evaluate relevant past performance based on scope, magnitude, and complexity. However, the solicitation also excludes broad project categories (e.g., dormitories/residential-type facilities, retail-focused projects, warehouse/industrial facilities), which may otherwise demonstrate comparable value, complexity, and execution risk. To support full and open competition consistent, and to ensure offerors can demonstrate relevant past performance, will the Government consider revising the relevancy definition by removing or minimizing the categorical exclusions, while retaining the objective thresholds (10-year recency, >$20M construction cost, >100K GSF, design/build or integrated delivery, and multiple trades)?"

The Government will not be revising the similar projects requirements.

There do not appear to be any bridging documents or as-built plans with the attachments on the SAM advertisement or in the Contractor Files shared via Google Drive. Please provide As-Built or Bridging drawings for Design Build teams to assess the scope relative to the existing buildings, review the building floor plans/layout, and provide a response to the RFP.

All available fire alarm and architectural as-builts were made accessible during the pre-proposal site visit and on a subsequest date during the following week.

There appear to be notes about the potential for CUI documents, however we do not see any of the bid documents marked accordingly as CUI for any category.

Can you confirm there are no CUI documents in the current bid set so we can determine handling restrictions for dissemination to potential vendors and consultants?

Any documents that have been provided in the Contractor Files Folder that pertain to the building scematics or provide detail regarding building components should be considered CUI.

112 SF1442 states period of performance is 810 calendar days while scope of work states 1095 with 180 days added if Option 1 is awarded. Which is correct?

1095 is the suggested total project duration however we are open for a reduced schedule as proposed by the offeror.

Will the arcflash testing being performed by the GSA interfere with any work being performed by the Contractor? Can a schedule for this work be shared with the Contractors?

Arcflash testing will not be performed by GSA. This should be contracted out to a third party testing agency.

Documents and scope narratives indicate shutdown work will need to be performed on weekends. It was mentioned during the virtual pre-proposal call that weekend work will not be allowed. Please advise how the design build contractor should structure estimate, schedule, and the proposal with respect to shutdowns, weekend work, and shift work if required.

Contractors should assume all work is to occur during normal business hours.

Work Item #2A states that the IRS has spare breakers for the EC to use as replacements for the failed breakers. Work item #2D also refers to “spare” breakers (it is assumed these are the same “spare” breakers”). It was said at the site visit that the IRS does not have any spare breakers to be used. Figure 1 – Breaker Detail also states that there are breakers on-site to be used for rotation.

Question: Does the EC provide NEW breakers to replace the failed breakers listed or are there spare breakers provided by the IRS?

EC to provide new breakers

Is retro-filling the failed breakers an option? Eaton believes that a cheaper and better overall option will be to retro-fill the existing breaker panels and install new Magnum PXR breakers in place of the older SPDs.

Yes, this is a option. However you will need to submit a deviation request from the original scope

ESME

It was noted at the site visit that the majority of spaces include raised access floor.

Is there product information available for the current floor to determine both load ratings for equip/scaffolding and figuring allowances for replacement of damaged components? Please provide a bid quantity to assume for replacement so that all proposals are equal in terms of scope.

The government will not provide an assumed amount for broken raised floor components as this is strictly means ans methods. It should be assumed that existing conditions be preserved.

There are a significant amount of GSA and PBS reference documents provided but it is unclear which are applicable to the scope of the contract. For example, COBie standards are included yet we are not being provided a native model of the facility nor do we believe the intent is to create new 3d models for the building with COBie information integrated. Please clearly define the design submittals and the governing criteria for the preparation of proposals.

The SOW determines which documents and/or portions of documents will be applicable.

Specification notates responsibility for extensive lifecycle cost analysis which would involve many systems outside of the current scope (e.g. Cooling Towers).

Please confirm DB Contractor scope relative to gBUILD would be limited to providing information on the new construction within scope for input into the existing database.

Confirmed

Since no existing models or full sets of record documents are available and many portions of the existing facilities are outside of this scope of work, please confirm specifications related to BIM are not applicable.

Confirmed

It was mentioned at the site visit that P-100 was no longer a viable governing document due to administrative direction in February of 2025. Attachment 05 and other portions of the bid documents indicate P-100 2021v w2022 addendum is the primary governing criteria. Please advise what codes, standards and criteria will govern the contract.

References to P-100 are replaced by the Core Building Standards document.

It was mentioned at the site visit that all work will be performed under escort and escorts will be provided by the Government or User at no cost to the contractor and no limit on the number needed. Please confirm that this is correctly understood as stated.
