Collin County is seeking professional programming, design, cost-estimating and construction-administration services for a new single-story juvenile-detention building, along with renovation of the existing detention-administration area. The solicitation gives the county a defined design and procurement scope, but it does not yet establish how many housing units or classrooms the new building will contain.
The current request follows a more specific concept presented by county juvenile-probation officials in 2023. That earlier plan proposed a 14,000-square-foot housing cluster on the north side of the John R. Roach Juvenile Detention Center at 4700 Community Avenue in McKinney. It carried a $20.089 million planning figure and an estimated October 2028 completion date.
Those 2023 figures are useful benchmarks, not final specifications in the 2026 solicitation. The current RFQ packet says the number of housing units and classrooms will be determined during programming, using the projected juvenile-detention population. That distinction matters: the county is procuring the work needed to define the project, while important questions about capacity remain open.
What Collin County is seeking now
RFQ 2026-304 combines several stages of professional work. The selected team would provide programming and design, prepare cost estimates and handle construction-administration services. The physical scope pairs a new single-story detention building with changes to the existing administration area.
The programming phase is where the county expects the housing-unit and classroom counts to be resolved. The RFQ ties those decisions to projected detention population rather than carrying the earlier concept forward as a fixed configuration. The record therefore supports a project direction — added detention space and an administration renovation — without supplying a final unit count, classroom count or updated construction figure.
The design work has an identified funding source. A Commissioners Court agenda record assigns it to Collin County’s 2023 Proposition A bonds under account FI23JUVP. That record specifically identifies funding for design work; the $20.089 million number comes from the 2023 planning presentation and should not be treated as a new price established by the 2026 RFQ.
Why the county previously said more capacity was needed
The county’s 2023 juvenile-probation planning presentation put the proposed expansion in the context of both population and daily operations. It reported that the existing facility had 144 beds, while its recent average daily population was 83 and its peak had exceeded 110. The presentation projected that the facility would reach capacity within six years.
The gap between 144 total beds and an average population of 83 did not mean all of the remaining beds were freely interchangeable. According to the presentation, 10 of the facility’s 12 pods were used throughout the year, and an eleventh opened during peak periods. Pod assignments also had to account for age, gender, treatment and safety, as well as the required separation of youths before and after adjudication.
Those operating constraints explain why the county’s capacity concern was not based on the overall bed count alone. A facility can have beds on paper while having fewer practical placement options for a particular group. The 2023 record connected the proposed housing cluster to that pod-use problem and the projected growth in the detention population.
How the earlier concept compares with the current RFQ
The 2023 and 2026 records answer different questions. The earlier presentation described a proposed size, location, cost and completion target: 14,000 square feet, attached to the north side of the McKinney detention center, with a $20.089 million planning figure and completion then estimated for October 2028. It also laid out the population and pod-use rationale for adding capacity.
The 2026 records show the county now seeking the professional services needed to program, design, estimate and administer construction for a new single-story building and an administration-area renovation. They identify Proposition A bond funding for design and explicitly leave the housing-unit and classroom counts to the programming work.
Read together, the records show continuity in the county’s goal but not a finalized copy of the 2023 concept. Added detention capacity remains the central purpose, and the earlier McKinney proposal remains the documented historical benchmark. But the current procurement makes clear that programming will determine key details. The earlier $20.089 million figure and October 2028 target should likewise be understood as 2023 planning benchmarks rather than newly confirmed cost and schedule commitments.
Two July deadlines
The immediate dates apply to the professional-services solicitation. Questions about RFQ 2026-304 are due at 2 p.m. July 16, 2026. Statements of qualifications are due at 2 p.m. July 30, 2026, a deadline also listed in the county’s legal notice.
For residents following the project, the clearest dividing line is between what the county has documented and what the programming phase still must settle. The county has identified the type of building, the related administration renovation, the design funding source and the procurement deadlines. The final housing and classroom configuration remains open, while the only supplied cost and completion figures belong to the earlier 2023 concept.
