NAICS Classification 236210 Government Contracts

The USPFO for NH awarded W50S8A26PA021 to Fleet Wave Construction, in the amount of $57,000 for B145 DCMA Office Space Renovation.

The general purpose of the contracts is to obtain craft labor and corrosion control services here at Kennedy Space Center. Craft labor and corrosion control includes, but is not limited to, all tasks and resources necessary to install, field fabricate and modify ground support equipment systems/subsystems to execute repairs and configuration change activities in support of Spaceport customer project. Met-Con has historically provided this service, as a subcontractor, most recently to Amentum under the Consolidated Operations, Management, Engineering and Test (COMET) contract, providing personnel who have specialized experience at KSC for over 20 years. They possess a knowledge that is critical to the execution of the Artemis mission that no other company can provide to a schedule that supports mission success. KSC's craft labor and corrosion control operations are reactive, requiring rapid adaptation as maintenance needs emerge during performance. Onboarding a new contractor would introduce schedule delays due to the learning curve and unfamiliarity with KSC-specific requirements. Met-Con is already established and integrated with the Kennedy Space Center team, making them the optimal choice for continuity. A one year, sole-source, award to Met-Con will maintain operational momentum while freeing Government resources to develop a competitive, long-term solution in support of the Administrator's direction. This requirement is critical to NASA’s Artemis campaign and its overall mission to safely land humans on the lunar surface. The Artemis campaign’s timeline, and its included mission dates, are a vital component of the government’s need. For reasons discussed below, delays to mission execution as a result of developmental challenges are likely to result in mission failure. These contracts are necessary to ensure that development of a lunar landing capability is complete in time to support NASA’s Artemis missions.

REQUEST FOR INFORMATION (RFI) BUILDING 215 ADVANCED MEASUREMENT LABORATORY (AML) CLEANROOM REPAIR AND HEPA FILTER REPLACEMENT Solicitation/Reference No.: 1333ND26RNB190014 1. PURPOSE OF THIS REQUEST FOR INFORMATION The National Institute of Standards and Technology (NIST) is conducting market research pursuant to Federal Acquisition Regulation (FAR) Part 10 and FAR 15.201 to obtain industry feedback concerning the scope, schedule, phasing, cleanroom outage requirements, technical and performance risks, and estimated construction cost associated with the Building 215 Advanced Measurement Laboratory (AML) Cleanroom Repair and HEPA Filter Replacement project. NIST previously solicited this requirement under Solicitation No. 1333ND26RNB190014. NIST did not receive an acceptable offer under that solicitation. NIST is therefore reassessing the requirement and acquisition approach before determining whether and how to resolicit the project. NIST is particularly interested in identifying aspects of the requirement that may materially affect industry participation, constructability, schedule feasibility, pricing, risk, or the ability of contractors to submit competitive proposals. Industry is encouraged to provide candid feedback and to identify recommended changes that could improve constructability, competition, schedule feasibility, cost certainty, and overall project execution while continuing to meet NIST’s mission and cleanroom operational requirements. 2. RFI / MARKET RESEARCH NOTICE THIS RFI IS ISSUED SOLELY FOR INFORMATION AND ACQUISITION PLANNING PURPOSES. IT DOES NOT CONSTITUTE A REQUEST FOR PROPOSAL (RFP), INVITATION FOR BID (IFB), REQUEST FOR QUOTATION (RFQ), OR OTHER SOLICITATION. The Government does not intend to award a contract based on responses to this RFI. Responses will be treated as information only and shall not be construed as offers or proposals that can be accepted by the Government to form a binding contract. The Government will not reimburse respondents for costs incurred in preparing or submitting information in response to this RFI or for participating in any follow-up discussions. This RFI does not obligate the Government to issue a solicitation or award a contract, nor does it restrict the Government’s ultimate acquisition approach. Respondents are advised that information submitted in response to this RFI may be used by NIST in developing or revising the acquisition strategy, statement of work, specifications, schedule, phasing requirements, outage requirements, Government cost estimate, and future solicitation. Respondents should clearly identify and mark any proprietary, confidential, or commercially sensitive information contained in their responses. Respondents should avoid including proprietary information unless necessary to provide a meaningful response. 3. PROJECT BACKGROUND The project involves repair and modernization work within the Building 215 Advanced Measurement Laboratory cleanroom located at the NIST Gaithersburg Campus. The AML cleanroom encompasses approximately 1,800 square meters and includes approximately 750 square meters of Class 100 cleanroom space. The facility supports sensitive NIST research activities and contains specialized and, in some instances, irreplaceable scientific equipment. The project generally includes, but is not limited to: • Replacement of approximately 1,200 terminal supply HEPA filters; • Repair and/or modification of HEPA filter connections; • Testing, balancing, certification, and recertification of affected HEPA filters and cleanroom spaces; • Replacement of approximately 70 variable air volume (VAV) terminal units; • Replacement of approximately 54 airflow monitoring devices; • Installation of approximately 32 exhaust air control valves; • Modification and repair of associated ductwork; • Rebalancing of associated air-handling and exhaust systems; • Verification and repair, as required, of existing capped ductwork; • Controls-related work; • Cleaning, testing, balancing, commissioning, and cleanroom certification associated with each affected area; and • Protection of existing cleanroom spaces, research operations, and sensitive scientific equipment throughout construction. Detailed project drawings, specifications, and/or relevant portions of the previously issued solicitation may be attached to this RFI or otherwise made available through SAM.gov for purposes of industry review. 4. CURRENT PHASING AND OUTAGE CONCEPT NIST’s previous acquisition strategy was developed to minimize disruption to ongoing research operations by performing the work through phased cleanroom outages rather than shutting down the entire cleanroom for the duration of construction. The previous requirement contemplated 19 construction phases consisting of 18 Critical Cleanroom Outage Phases and one Non-Critical Phase. For each Critical Cleanroom Outage Phase, the contemplated outage period was approximately nine calendar days, generally structured as follows: • Outage/construction activities begin at approximately 7:00 p.m. on Friday; • Work proceeds continuously, including 24-hour-per-day/seven-day-per-week operations, as necessary; • Construction, startup, testing, balancing, cleaning, commissioning, and applicable cleanroom certification are completed during the outage period; and • The affected cleanroom area is required to achieve Ready for Re-Occupancy by approximately 7:00 a.m. on the second following Monday. Ready for Re-Occupancy generally means that required construction, startup, testing, balancing, cleaning, commissioning, and applicable cleanroom certification have been completed; the affected area is operationally capable of supporting its intended use without material restriction; and no deficiencies remain that materially impair safe occupancy or cleanroom operations. The previous requirement also contemplated maintaining unaffected cleanroom bays in operation to the maximum extent practicable and included the possibility of limited additional weekend outages affecting larger portions of the cleanroom. NIST recognizes that these operational constraints may significantly affect contractor staffing, sequencing, subcontractor availability, construction risk, pricing, and schedule feasibility. NIST is specifically seeking industry feedback concerning these requirements. 5. INFORMATION REQUESTED FROM INDUSTRY Respondents are requested to review the project information provided with this RFI and address the following topics. Respondents are not required to answer every question; however, detailed and candid responses are encouraged. A. Outage Feasibility and Constraint Identification • Critical Path Bottlenecks: Identify the specific trade activities that present the highest risk to achieving a 9-day bay outage window. • Realistic Outage Duration: Based on your experience in occupied nanofabrication facilities, what is a realistic, achievable calendar-day duration to complete a single cleanroom bay/module from shutdown to final recertification? • Risk & Impact Analysis: Explain how the current 24-hour, 9-day limit impacts project risk, labor density, safety, quality assurance, and total cost (including risk contingencies for $8,000/day liquidated damages). • Phasing & Mock-Up Alternatives: Would executing a "mock-up bay" or initial trial phase establish a viable baseline for subsequent production bays? B. Construction Cost Estimate Based on the information provided, what is industry’s rough-order-of-magnitude (ROM) estimated construction cost for the complete project? Respondents may provide either a specific estimated amount or a reasonable estimated range. • To the extent practicable, please identify the approximate portion of the ROM estimate attributable to: • Direct construction work; • HVAC/HEPA/VAV work; • Controls work; • Testing and balancing; • Commissioning and cleanroom certification; • Premium time, shift work, or 24/7 outage staffing; • General conditions; • Phasing and temporary protection; • Contingency/risk allowance; and • Other significant cost drivers. • Approximately what percentage or dollar amount of the estimated construction cost is attributable specifically to the current nine-day phased-outage approach? • If NIST modified the outage durations or phasing strategy, what approximate cost reduction or increase would industry anticipate? ROM estimates submitted in response to this RFI are requested solely for market research and acquisition planning. They will not constitute offers, proposals, bids, quotations, or binding commitments. C. Experience Working in an occupied Nano-Fab Cleanroom • The previous solicitation included Evaluation Factor #2 which required that the contractor have completed a minimum of two (2) HEPA Filter replacements in an occupied laboratory within the previous six years. Based on your experience in occupied nanofabrication facilities, is this a realistic and practical requirement? D. Competition and Industry Participation • Based on the project as currently structured, would your company consider submitting a proposal if NIST resolicits this requirement? Yes / No / Possibly Please explain the primary factors influencing your answer. • What aspects of the previous/current requirement would discourage your company or other qualified contractors from submitting a proposal? • Are the project’s size, bonding requirements, insurance requirements, cleanroom experience requirements, key personnel requirements, outage schedule, liquidated damages, fixed-price structure, or other contractual requirements likely to limit competition? • What changes, if any, would materially increase the likelihood that qualified contractors would compete for this project? • What type of contractor and subcontractor experience should NIST reasonably require without unnecessarily restricting competition? E. Additional Industry Feedback • Please identify any requirement, specification, schedule constraint, contract term, risk allocation, or other issue not addressed above that NIST should consider before resoliciting this project. • Please provide any additional recommendations that could improve competition, constructability, schedule reliability, cost certainty, or successful project execution. 6. RESPONDENT INFORMATION Respondents are requested to provide the following: • Company name; • Company address; • Name, title, telephone number, and email address of the point of contact; • Unique Entity ID (UEI), if available; • Business size and socioeconomic status under the anticipated NAICS code; • Relevant experience performing comparable cleanroom, laboratory, HVAC, HEPA filtration, controls, testing/balancing, or phased occupied-facility construction; • Whether the respondent would anticipate performing as a prime contractor or subcontractor; and • Whether the respondent would be interested in participating in a future industry day, one-on-one market research meeting, or site visit concerning this requirement. 7. RESPONSE INSTRUCTIONS Responses should be submitted electronically to [email protected] and [email protected] no later than October 14, 2026.
