Meeting Minutes Pre-Proposal Conference

July 15, 2026 at 10:00 am EDT Solicitation No: 47PB5226R0001 Armed Forces Retirement Home

Sheridan Building Construction Services 3700 North Capitol Street NW

Washington, DC

Contracting Officer: Tim Novak (Absent) Contract Specialist: Robert “Mickey” Kramarik-Boyle Contracting Officer's Representative: Todd Patterson Project Manager: William Faustman, PE GSA Supervisory Project Executive: Tiffany Brown CMA Mike Olson Architect/Engineer Firm POC: AE Works - Michael Carrol AFRH: Justin Steffens AFRH: Jeyaharan Sivapalarasah

Opening Remarks:

● Tiffany Brown, representing the General Services Administration (GSA), presented an overview of the project's historical background. She highlighted the unique challenges and operational complexities associated with executing major construction activities within an occupied residential facility, noting that this project is distinct for GSA as it involves residential housing rather than a standard commercial office building. Additionally, Tiffany

Brown detailed the established guidelines and behavioral standards required for contractors operating in environments where direct interaction with residents will occur. She also discussed the strategic partnership between GSA and the Armed Forces Retirement Home (AFRH), emphasizing the collaborative efforts of both agencies to enhance the quality of life for resident veterans. Following the introduction of key project team members, Justin Steffens of AFRH was introduced to address the attendees.

● Justin Steffens of AFRH expressed appreciation to all attendees for their interest in this construction project. He clarified that the operations and construction of this facility are not funded by federal tax revenues; instead, funding is appropriated by Congress from the Armed Forces Retirement Home Trust Fund. This trust fund is capitalized through disciplinary fines levied on active enlisted military personnel, monthly salary deductions from enlisted members, and resident fees. Justin Steffens emphasized that because the construction will occur within an occupied residential housing center, personnel should anticipate that residents may inquire about and observe the ongoing work. He also provided an overview of the campus's history and the core mission of the AFRH, reminding prospective offerors that the funding for this project is derived directly from active-duty service members and veterans. Justin Steffens commented that while the campus is listed on the National Register of Historic Places, the Sheridan building itself is not, although exterior work is subject to review by appropriate authorities. Justin Steffens also stated that ongoing campus activities include a functioning childcare center and a National Guard presence, which is currently relocating to an 80-acre area in the south.

Sign-In Sheet: (Mickey)

Attendees were reminded that they are required to complete the sign-in attendance sheet. The Government stated that this sheet would be published along with the meeting minutes from the conference via an amendment to the solicitation on sam.gov.
