County weighs buying Envision Building vs. new construction; staff shows cost, life‑cycle and parking tradeoffs

Sedgwick County staff on Aug. 19 presented an updated due‑diligence briefing on the county’s May purchase agreement for the Envision Building and compared three options for county administrative space: buy and remodel Envision, build a full‑size new administrative building at Third & Main, or build a reduced‑footprint administration building and relocate some row offices to existing county properties.

Tanya Cole (county staff) and Justin Graham of Schaefer Architecture delivered a multi‑discipline facilities assessment and cost comparison that included structural, mechanical, electrical, elevator, roof and environmental reviews. They reported the Envision Building was constructed in 1977–78, has five stories plus basement and a gross exterior footprint around 74,860 square feet (interior floor area in the low‑to‑mid 70,000s depending on measurement) and an existing parking footprint that could be expanded by paving to roughly 180 spaces.

Purchase agreement and timing

- The commission previously executed a purchase agreement for the Envision Building (May 14). Tanya Cole said the due‑diligence period in the agreement expires Sept. 11; if the county takes no additional action the deal would move to closing 30 days after that date per the agreement terms as presented. - Bond proceeds and timing: staff finance analysis reported approximately $14.4 million available in bond proceeds and investment earnings from an original $13.2 million issuance dated Oct. 2, 2024; federal/state rules require spending 85% of that issuance within three years and 100% within five years, which staff said factors into project timing.

Cost and life‑cycle comparisons (staff estimates presented)

- Envision purchase + remodel: purchase price cited at $11,950,000. Staff estimated initial project costs (purchase + remodel and site work) of about $30.5 million and a 50‑year combined project + life‑cycle total of roughly $41.7 million (includes major maintenance allowances, elevator modernization, chiller replacement and utility cost forecasts). - Third & Main (full program): new construction for the full administrative footprint (approx. 76,560 sf) — project cost estimated about $39.3 million; 50‑year total estimated about $49.4 million. That site was estimated to deliver ~300 parking spaces in a campus configuration but carries additional site/streets work. - Third & Main (reduced footprint): smaller new building (approx. 54,350 sf) that would require relocating some row offices to other county buildings — project cost estimated about $32.2 million; 50‑year total estimated about $40.0 million when relocation and remodel costs at other county buildings are included.

Major cost drivers and facility considerations

- Envelope and systems: Schaefer and engineering subconsultants reported the Envision Building is structurally solid but needs exterior caulking and select panel/finish repairs, elevator modernization (estimated $850,000), chiller replacement (approx. $245,000 per chiller), and sprinkler work on one floor. - Parking and site: Envision could be expanded to roughly 180 spaces by adding a paved lot; Third & Main alternatives provided more parking but would require street restriping and potential right‑of‑way changes. - Program fit: staff produced floor plans showing how county departments (treasurer, clerk, register of deeds, finance, HR, county counselor, commissioners and manager) would fit across Envision or new construction; several departments would share break rooms and meeting spaces.

Commissioner questions and next steps

Commissioners asked about comparability of costs, assumptions behind new‑construction per‑square‑foot estimates, opportunities for value engineering (less glass, material substitutions), and the extent to which the Envision numbers reflect unresolved unknowns. Tanya Cole said staff can rework assumptions and that if the commission wishes to pursue Third & Main staff will prepare deeper analysis and coordination with the city. The meeting record shows commissioners split in views; multiple members favored keeping the Envision option on the table and continuing discussion, while others raised concerns about lifecycle costs and parking constraints.

Staff recommendation and procedural schedule

Staff said it will return with refinements; the purchase agreement due‑diligence window ends Sept. 11, so the commission has an option at upcoming Sept. meetings to act before due diligence expires. If the commission does not direct otherwise, staff indicated the default course in the purchase agreement is to proceed toward closing.
