Quest Diagnostics - Warehouse Lift in Lewisville, TX

Quest Diagnostics completed a $100,000 renovation at 2501 South State Highway 121 in Lewisville, adding a lift and stairway to connect existing laboratory space with the warehouse. The project involved 240 square feet of new construction within Denton County, registered with the Texas Department of Licensing and Regulation in November 2024. The filing specified a start date of January 2025 and a planned completion in February 2025.

The work was classified as a renovation and alteration focused on accessibility improvements. The scope explicitly described the addition of a lift and stair from the existing laboratory space into the warehouse. This physical modification aimed to improve internal circulation between distinct functional areas of the facility. The registered accessibility specialist for the project was Jeffery L Kelley, ensuring compliance with state standards during the design and construction phases.

Ware Malcomb served as the design firm of record for this initiative. The firm is responsible for the architectural and engineering plans that guided the physical changes. The project was privately funded on private land for private use, indicating it was an internal capital investment by the owner rather than a public infrastructure development. The estimated cost of $100,000 for the 240 square feet results in a cost per square foot of $417.

In the context of local construction activity, this project’s estimated cost is below the county median for renovation and alteration filings in Denton County.

Despite the shorter timeline, the cost per square foot is above the county median of $81 per square foot, reflecting the specialized nature of installing a lift and stair system.
