Addition/Alteration Administration

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. The clock time is the same instant in the two zones (CT is one hour ahead of MT, so 2:00 pm CT and 11:00 am MT are not identical; the new deadline is 11:00 am MT, which is 12:00 pm CT, one hour earlier than before). Applicants should plan to submit by the earlier time.
• Agency name corrected from "Department of the Air Force" to "Department of the Space Force" as the agency on whose behalf market research is conducted at Buckley SFB.
• Facility address added: "Buckley Space Force Base, Colorado 80011" appears in the title block, giving the project location explicitly.
• Minor wording and formatting edits to the attachment name, paragraph breaks, and phrasing (e.g., "Sources Sought Notice" without the "_" suffix change, and the Mission Criticality and background paragraphs reflowed) do not change requirements.

Why it matters: the earlier submission deadline and the corrected agency designation are the substantive changes. Teams should adjust their internal submission timeline to meet the 11:00 am MT cutoff and ensure their capability statement references the Space Force correctly. Technical scope, CCL ($6,622,000), acquisition approach, and phasing requirements are unchanged.

• Response deadline moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The date is unchanged, but the time is now stated in Central Time, which is the same clock time 2:00 pm CT (3:00 pm MT?)... to be precise, 11:00 am MT equals 12:00 pm CT, so the cutoff is effectively two hours later in local Colorado time; applicants should confirm the intended zone and submit early.
• Agency reference corrected: the market research is now described as being conducted on behalf of the Department of the Air Force, replacing the Department of the Space Force. Buckley SFB remains the installation, so applicants should note the sponsoring department in their capability statements.
• Formatting-only edits (added "(SFB)" after Colorado in the title block, spacing and punctuation tweaks) carry no scope implications.

Why it matters: the deadline change is the only one that affects submission logistics, so respondents should send by the earlier of the two interpretations to avoid a missed cutoff. The department change does not alter requirements, scope, CCL, or acquisition method.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. Both are the same moment in time (Central is one hour ahead of Mountain), so the effective deadline is unchanged, but the time zone and clock time as written are different. Applicants should confirm they're working from the new stated time.
• Sponsoring department wording changed from "Department of the Air Force" to "Department of the Space Force" in the Problem and Background Statement, reflecting that Buckley SFB is a Space Force installation.
• Base address added to the title block ("Buckley Space Force Base, Colorado 80011"), giving applicants a ZIP code for site location.
• Minor wording and formatting cleanup: the filename changed slightly, and some spacing and line breaks were adjusted. No change to scope, requirements, the $6,622,000 construction cost limitation, the 5,800 SF addition, the 695 SF renovation, the 35% concept design, or the phased Progressive Design-Build approach under 10 USC 2808a.

For applicants, the substantive takeaway is the deadline time-zone change, which is cosmetic in effect, and the corrected sponsoring department name, which matters for accurate capability statements.

• Response deadline moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The clock time is the same instant only if the zones match, but the notice now states Central Time, so applicants should confirm the exact cutoff in their own time zone and send responses early.
• Issuing agency wording changed: the notice now says research is conducted "on behalf of the Department of the Air Force" instead of "Department of the Space Force." Applicants targeting Space Force customers should note the attribution change, though the project scope itself is unchanged.
• Minor formatting and wording edits to the attachment (title spacing, "Buckley Space Force Base (SFB)" phrasing, paragraph spacing) carry no substantive scope change.

Why it matters: the earlier deadline time was a Mountain time cutoff, and the revised one is Central. Missing the window by an hour could disqualify a late sender, so the response should go out before 2:00 pm CT on 21 October 2026. The agency change does not alter eligibility, the 5-page limit, the $6,622,000 cost limitation, or the 10 USC 2808a OTA approach.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. The clock time is the same instant in Colorado, so the practical effect is that responses are due one hour earlier relative to the old stated time, and applicants should not rely on the old 2:00 pm CT cutoff.
• Sponsoring department renamed from "Department of the Air Force" to "Department of the Space Force" in the background statement, reflecting the correct service for Buckley SFB.
• Base address added to the title block (Buckley Space Force Base, Colorado 80011), which helps applicants confirm the site location but does not change scope.
• Attachment file name changed from "Sources_Sought_Notice_.pdf" to "Sources_Sought_Notice.pdf" with no content effect.

Why it matters: the earlier deadline time is the only change that affects submission planning. Respondents using the 2:00 pm CT time should confirm their email is sent before 11:00 am MT. The department and address corrections do not alter requirements, scope, the $6,622,000 construction cost limitation, or the 5-page narrative limit.

• Response deadline time changed: Submissions were due 21 October 2026 at 11:00 am MT in the previous version; the updated version sets it at 2:00 pm CT, which is the same instant in time zone terms only if the offset is accounted for, but the stated time and zone differ, so applicants should confirm the exact cutoff.
• Agency reference corrected: The market research is now described as being conducted on behalf of the Department of the Air Force, replacing the previous reference to the Department of the Space Force (the base itself remains Buckley Space Force Base).
• Minor text and formatting edits: The project location now reads "Buckley Space Force Base (SFB)" with the abbreviation added, and some spacing and line breaks were adjusted.

Why it matters: the time-zone and time change affects when responses must reach the POCs by email, so applicants should use the stricter 2:00 pm CT deadline to be safe. The agency change does not alter the scope, $6,622,000 CCL, OT authority, or Progressive Design-Build approach.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. The clock time is the same instant in the two zones, so the practical effect is that the cutoff is now stated in Mountain Time; applicants should confirm the new time against their submission schedule.
• Sponsoring department wording changed from "Department of the Air Force" to "Department of the Space Force" in the background statement, reflecting the Space Force ownership of Buckley SFB. Applicants should note the correct service in their capability narratives.
• Installation address added to the title block ("Buckley Space Force Base, Colorado 80011"), a minor identifier rather than a scope change.

No changes were made to the project scope, square footage (approximately 5,800 SF addition and 695 SF renovation), the $6,622,000 Construction Cost Limitation, the OTA/10 USC 2808a acquisition approach, the three-phase Progressive Design-Build structure, or the response requirements (5-page limit, email submission). The main action item for applicants is the revised deadline time and the corrected department reference.

• Response deadline time changed: Responses were due 21 October 2026 at 11:00 am MT; now due 21 October 2026 at 2:00 pm CT. The date is unchanged, but the cutoff time is different (Mountain vs. Central time zone shift, with the stated deadline now 3 hours later in clock time for Central).
• Sponsoring organization wording changed: The background statement now says USACE is acting on behalf of the Department of the Air Force, previously the Department of the Space Force. Applicants should note the stated customer service branch differs in the notice, though the base itself (Buckley SFB) is unchanged.
• Minor formatting/wording edits: The base name is now shown as "Buckley Space Force Base (SFB)" in the header, and spacing, line breaks, and the placement of the "Mission Criticality" and project description paragraphs were adjusted. These have no effect on requirements.

Why it matters: Applicants should confirm the response deadline against the new 2:00 pm CT time and verify which service branch is named as the requiring customer, since the notice itself is inconsistent on the branch. Technical scope, the $6,622,000 construction cost limitation, the 5,800 SF addition, the 695 SF renovation, and the acquisition approach are unchanged.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. The clock time is the same instant in both zones only if the earlier time was also Mountain; in practice the stated cutoff is now 11:00 am Mountain, so responders should treat the deadline as one hour earlier than the 2:00 pm Central time previously listed.
• Agency name corrected: the Department of the Air Force is now the Department of the Space Force as the customer for this market research.
• Buckley SFB address added: "Colorado 80011" was added to the project title block.
• Background wording tightened: the existing Fire Station's critical undersizing and use of dormitories and training rooms as makeshift offices is restated with slightly different phrasing, but the substance is unchanged.

Why it matters: Respondents must submit their five-page narratives by the earlier, Mountain-time cutoff, and should confirm that their submission timing reflects that deadline. The Space Force reference matters for past-performance and customer-experience framing in capability statements.

• Response deadline time changed: The submission cutoff moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The date is unchanged, but the time is now expressed in Central Time, which is one hour later than Mountain Time. Applicants should note the new zone in their planning.
• Military department named changed: The market research is now described as being conducted on behalf of the Department of the Air Force, rather than the Department of the Space Force. This is a stated sponsor/agency reference change; the facility remains at Buckley Space Force Base.
• Base name formatting: "Buckley Space Force Base" now carries the "(SFB)" abbreviation in the header; this is cosmetic only.

Why it matters: The deadline is the key operational change. Responses are due by the same date but one hour later on the Central clock, so firms in Mountain Time should confirm the exact local submission time. The department attribution change is a clarification of the sponsoring service and does not alter scope, requirements, or restrictions.

• Response deadline moved up in time of day: The email response cutoff changed from 2:00 pm CT to 11:00 am MT on 21 October 2026. Both are the same moment in time when converted (Central is one hour ahead of Mountain), so applicants should confirm they are not relying on a different deadline, but the local-time wording is now Mountain.
• Base address added: The header now includes "Buckley Space Force Base, Colorado 80011," giving applicants a ZIP code for the installation.
• Customer named differently: The background now refers to the Department of the Space Force instead of the Department of the Air Force as the organization USACE is acting for. This matters for applicants positioning past performance and security or agency-specific qualifications.
• Minor wording cleanup: The title of the notice file changed (dropping "Sources_Sought_Notice" in favor of a shorter name), and some phrasing was tightened, but the scope, cost limitation ($6,622,000), 5,800 SF addition, 695 SF renovation, OT approach under 10 USC 2808a, and phased occupied-facility requirements are unchanged.

• Response deadline time changed: Responses are now due 21 October 2026 at 2:00 pm CT, previously 11:00 am MT. Both are the same instant in time only if read carefully, but the stated zone and clock time differ, so applicants should confirm the exact cutoff and submit early.
• Military department named changed: The background statement now says market research is conducted on behalf of the Department of the Air Force, previously the Department of the Space Force. Applicants should note the stated sponsoring department in their capability narratives.
• Installation reference: Buckley is now described as "Buckley Space Force Base (SFB)" in the header, consistent with the body text, with minor wording and punctuation cleanup elsewhere.
• Background paragraph spacing: Paragraphs were reformatted and split, but the content is otherwise unchanged.

Why it matters: The deadline time and the sponsoring department are the substantive changes. Missing the revised cutoff could disqualify a response, and the department wording may matter for how capability statements are framed.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. The time is the same instant in both zones (both 2:00 pm CT equals 1:00 pm MT, so the deadline is actually one hour earlier in real terms), so applicants should plan to submit before 11:00 am MT to avoid missing it.
• Sponsoring department renamed from "Department of the Air Force" to "Department of the Space Force" in the background statement, reflecting the project's Buckley Space Force Base owner.
• Installation address added to the header: Buckley Space Force Base, Colorado 80011.
• Minor wording and formatting cleanup: the attachment filename changed, line breaks and spacing were adjusted, and the period of performance line is still cut off at "Notice to Proceed."

Why it matters: the deadline change is the only item with practical consequences, since a misread time zone could cause a late submission. The department rename and address are corrections that do not alter the scope, CCL, or acquisition approach.

• Response deadline moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The cutoff is the same instant in time (both are 11:00 am MT / 12:00 pm CT would differ; the new time is 2:00 pm CT, which is 1:00 pm MT), so the effective deadline is about one hour later in Mountain Time.
• Sponsoring organization changed from "Department of the Space Force" to "Department of the Air Force" as the agency USACE is conducting market research for. Applicants should confirm which service branch will fund and oversee the project, since this affects the customer relationship and any service-specific requirements.
• Minor wording and formatting edits to the project description, including reflowed paragraphs, added spacing, and the base name written as "Buckley Space Force Base (SFB)" in the header. No changes to scope, square footage (approximately 5,800 SF addition and 695 SF renovation), construction cost limitation ($6,622,000), acquisition approach (OT under 10 USC 2808a, progressive design-build), or phasing requirements.

Why it matters: the deadline shift is small but applicants should update calendars and confirm submission timing in Central Time. The service-branch change may affect how capability statements are framed for the customer.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. Both are the same moment in time (Mountain and Central differ by one hour, so 11:00 am MT equals 12:00 pm CT, and 2:00 pm CT is a later time). Applicants should treat the earlier, 11:00 am MT, as the operative deadline to avoid missing the cutoff.
• Organization name corrected from "Department of the Air Force" to "Department of the Space Force" as the customer on whose behalf market research is conducted. Relevant for past-performance and capability framing toward Space Force facilities.
• Installation address added to the title block: "Buckley Space Force Base, Colorado 80011."
• Sources Sought notice file name changed (dropped "Notice" suffix variant), with no effect on requirements.

Scope, requirements, the $6,622,000 construction cost limitation, the 5,800 SF addition, 695 SF renovation, OTA/10 USC 2808a approach, and UFC 4-010-01 standoff requirements are unchanged. Applicants should simply update their submission timing and reference the Space Force customer name in their responses.

• Response deadline moved from 11:00 am (MT) to 2:00 pm (CT) on 21 October 2026. The two are the same instant in time-zone terms (MT is one hour behind CT), so the effective cutoff is unchanged, but applicants should note the new stated time zone and format.
• Issuing organization changed in the background statement: the market research is now described as being conducted "on behalf of the Department of the Air Force" instead of the Department of the Space Force. Buckley SFB remains the installation, so the work scope is unaffected, but applicants referencing the sponsoring service in their capability statements should align with the revised wording.
• Formatting and layout only otherwise: the project title, scope (5,800 SF addition, 695 SF renovation), $6,622,000 construction cost limitation, PDB/OTA approach, phasing, and antiterrorism requirements (UFC 4-010-01, 50-foot standoff) are unchanged in substance.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. Both are the same moment in time (CT is one hour ahead of MT), so the effective cutoff is unchanged, but applicants should note the new time zone and clock time when submitting.
• Agency name changed: the requesting department was renamed from "Department of the Air Force" to "Department of the Space Force" in the background statement, matching the Space Force base the project is located on.
• Address added: the title block now includes the base's ZIP code (Buckley Space Force Base, Colorado 80011). This is a location detail, not a scope change.
• Wording tightening only: the background and project sections were reflowed and minor phrasing was adjusted (e.g., "Fire Station (Facility B806)" context and paragraph breaks), with no change to requirements, the $6,622,000 cost limit, the 5,800 SF addition, the 695 SF renovation, the 35% design baseline, or the 420-day performance period.

Why it matters: the only practical action item is to submit by 11:00 am MT on 21 October 2026, and to confirm the Space Force reference in any capability statement.

• Response deadline time changed: The submission cutoff moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The date is unchanged, but the time is the same-day equivalent of a different instant, so confirm the new time against your submission timing.
• Military department named changed: The market research sponsor was reworded from "Department of the Space Force" to "Department of the Air Force." Applicants preparing qualifications should confirm which service is the sponsoring customer, since it can affect past-performance framing and points of contact.
• Facility and base naming: "Buckley Space Force Base" now appears with "(SFB)" after it in the background text, and the header drops "Colorado 80011" from the address line. These are cosmetic.
• Formatting and spacing: Minor whitespace and paragraph spacing differences; no scope, requirement, or restriction changed.

Why it matters: the deadline time shift is the one item that could cause a missed submission if applicants use the old 11:00 am MT cutoff. The Department of the Air Force reference should be checked against any related solicitation materials.

• Response deadline moved from 2:00 pm CT to 11:00 am MT on 21 October 2026. Both are the same moment in time (Central is one hour ahead of Mountain), so the effective deadline is unchanged, but responders in other time zones should note the stated time now reads in Mountain Time.
• Military department named changed from "Department of the Air Force" to "Department of the Space Force" in the background statement, reflecting that Buckley SFB is a Space Force installation.
• Facility address added to the header: Buckley Space Force Base, Colorado 80011.
• Minor wording and line-break cleanup elsewhere (e.g., "Sources Sought Notice" file name, spacing), with no change to scope, requirements, or the $6,622,000 construction cost limitation.

Why it matters: the deadline is functionally the same, but applicants should confirm they are working from the Mountain Time reading. The service-branch correction clarifies the customer and does not alter requirements, so responses should reference the Space Force.

• Response deadline moved from 11:00 am MT to 2:00 pm CT on 21 October 2026. The date is unchanged, but the time is now stated in Central Time, which is the same clock time (both are 11:00 am MT vs. 2:00 pm CT, a three-hour gap shift that places the deadline later in the day, effectively 2:00 pm CT is 1:00 pm MT). Applicants should treat the earlier of the two as the safe target.
• Issuing branch changed: the background now says the market research is conducted "on behalf of the Department of the Air Force" instead of "the Department of the Space Force." Buckley SFB is still the site, so applicants should note the sponsoring department in their own records and correspondence.
• Formatting-only edits: the base name is now "Buckley Space Force Base (SFB)" with the SFB abbreviation added, the file name gained a trailing underscore, and the sections were re-spaced. These do not affect requirements.

Why it matters: the deadline is the only operational change applicants must act on. The department name change does not alter the scope, CCL ($6,622,000), NAICS code, or the OTA/Progressive Design-Build approach, but it should be reflected in capability statements referencing the sponsoring agency.
