Two separate manufacturing plant additions on Spokane’s North Side are among significant industrial construction projects planned or underway here this year.

One is a massive $193 million expansion at the Jubilant HollisterStier LLC site in the Bemiss neighborhood, and the other is a $2.2 million addition at the Travis Pattern & Foundry Inc. plant in Mead.

Spokane-based pharmaceutical manufacturing company Jubilant HollisterStier broke ground in mid-February on a fourth-line expansion, which the company expects will double its injectable filing production capacity by 2025.

The project at the plant located at 3525 N. Regal comes on the heels of its recently completed $92 million, 50,000-square-foot third-line expansion.

The larger expansion will involve construction of a two-story, 160,000-square-foot building that will house a flexible manufacturing platform able to produce several types of vaccines. The fourth line will include a filling line, a shipping center, an electron microscopy lab, a packaging area and warehouse space.

Lydig Construction Inc., of Spokane Valley, is the contractor on the project, and Emeryville, California-based Integrated Project Services is providing design and engineering services.

Lydig and Integrated Project Services also teamed up on the third-line project.

As recently reported in the Journal of Business, Chris Preti, president and CEO of Jubilant HollisterStier, says the expansion projects will help the company advance vaccine preparedness on a national scale for future pandemics.

The company expects to add 450 jobs to the Spokane facility once both new lines are operational, bringing the total workforce at the plant to about 1,200 employees.

Jubilant HollisterStier received $149.6 million in American Rescue Plan funds for the expansion through an agreement with the U.S. Army, other Department of Defense agencies, and the Department of Health and Human Services.

About six miles northwest of the pharmaceutical manufacturing plant, Travis Pattern & Foundry is planning a facility expansion with a new 6,100-square-foot addition at 1413 E. Hawthorne Road, according to application information on a building permit issued in November by Spokane County.

Project representatives couldn’t be reached immediately for comment.

Garco Construction Inc., of Spokane, is the contractor on the expansion project, and Jason McDonald, an architect with Garco, is listed as the project architect, permit information shows.

Travis Pattern & Foundry is a family-owned aluminum, bronze, and iron castings company founded in 1922. Its 170,000-square-foot campus lies east of Newport Highway and west of the former Kaiser Aluminum Corp. Mead plant that closed in 2000.
