Construction Scope and Timeline

The scope of work involved additions to an existing structure rather than new construction on a vacant lot. The project was scheduled for a build window of 434 days, starting in January 2025 and targeting completion by March 2026. While the filing indicated a completion date in March 2026, the final inspection was successfully passed in April 2026. This timeline is longer than the median scheduled build window of 214 days for similar additions in Taylor County.

In terms of scale, this project is significantly larger than typical additions in the region. The estimated cost is above the county median of $400,000 for similar filings, placing it in the top quarter of expenditures. The $491 per square foot cost is also above the county median of $175 per square foot. These figures reflect the complexity of integrating a three-story addition into an existing academic and auditorium complex.
