Waukesha to consider final site plan for INNIO expansion

Listen to this article

Gas engine manufacturer INNIO has shared its final site plans for an 84,000-square-foot expansion at its facility in Waukesha.

The Waukesha Plan Commission will meet on Wednesday to review a final site plan, architectural review and certified survey map for a new building and combined parcels at 1101 W. St. Paul Ave. The address is currently home to international firm INNIO‘s 600,000-square-foot facility.

The 84,414-square-foot addition will feature a new end-of-line testing, painting and shipping space to support production of a new engine line, wrote Josh Meyerhofer, a senior project engineer at Baraboo-based MSA Professional Services, in a report to the city. The firm reviewed INNIO’s plans for the city of Waukesha.

The additional production lines are expected to bring in a “plethora of jobs” to the facility, the report showed. The addition will be made up of precast concrete panels and engine test cells on the southern edge of the addition will be built with cast-in-place concrete.

“The addition will be located mostly behind and to the west of the current facility, and minimally visible from the St. Paul Avenue corridor,” city officials said in a report. “The addition will serve as a state-of-the-art testing facility supporting a new engine line that INNIO intends to manufacture at this location.”

The project, called “Project Green,” “represents a substantial capital investment in the existing facility and underscores INNIO’s long-term commitment to its Waukesha campus,” write Andrew Dawson, chief financial officer at INNIO Waukesha Gas Engines, in a letter to city officials.

Other site improvements include new pavement and traffic patterns around the city to accommodate shipping, utility relocations and underground stormwater detention. Brookfield-based raSmith prepared a stormwater management plan for the addition.

The manufacturer is also asking the city to approve its final plans and a CSM to combine parcels it owns into one 38.7-acre lot. This will support future growth at the facility, officials added.
