3M Cold Room Racking in Roanoke, TX

The 3M Warehouse project at 300 Gateway Parkway in Roanoke involved the installation of 9,186 square feet of high-pile pallet racking within an existing structure. This addition to the existing building was registered with TDLR in April 2025 under the specific filing name 3M Cold Room Racking. The estimated cost for this scope of work was $142,032, which computes to $15 per square foot.

Structural Engineering & Design, Inc. served as the design firm of record for this construction project. Marcela Abadi Rhoads was the registered accessibility specialist associated with the filing. The project was noted as involving public funds, public land, or a Federally funded roadway project, a designation that often triggers additional regulatory scrutiny in Denton County.

Project Scope and Cost Context

The primary activity was the installation of pallet racking for high-pile storage. This is a distinct type of interior modification compared to structural expansions or new builds. The estimated cost of $142,032 is below the county median for similar additions to existing buildings, which stands at $420,000. The size of 9,186 square feet is also below the median size of 4,000 square feet for this category in Denton County filings over the last 24 months.

The cost per square foot of $15 is significantly below the county median of $151 per square foot. This disparity often reflects the nature of the work; racking installation is labor-intensive but does not involve the material costs of new concrete, steel, or roofing that drive up the average cost of other construction projects. The scheduled build window was 11 days, which is shorter than the county median of 153 days for comparable projects.

Regulatory Status and Closure

The project was registered with TDLR in April 2025, with a construction start date also listed as April 2025. The completion date on the filing was April 2025. TDLR closed the project file in April 2025, which marks the end of the accessibility review process for this construction. This status indicates that the regulatory requirements for the accessibility review were satisfied and the file was officially closed by the agency.
