Komatsu Mining Campus Takes Shape

The steel frame of a new office building rises over Milwaukee’s Inner Harbor.

The three-story, 176,000-square-foot building rose quickly this summer, part of a $285 million plan to build a new campus for Komatsu Mining and its P&H brand.

The plans, billed as the largest new urban manufacturing facility in the country, call for an office building, parking garage, training center, museum and automation lab as well as a 430,000-square-foot, three-story manufacturing facility.

Located at the eastern end of E. Greenfield Ave., the complex will be known as South Harbor Campus. From it will emerge mining shovels, shipped in pieces, that weigh over three million tons and can lift 120 tons at a time.

Employees of Hunzinger Construction, with subcontractor Michels Corp. and a host of other firms, continue to pound hundreds of piles into the ground for the manufacturing facility’s foundation and, judging by the rows of piles still sitting on the site, they still have quite a bit of work to do.

But the office building bears the ceremonial signs of having its last structural steel slotted into place, flags and a small Christmas tree. The tree is used by steelworkers as a marker of reaching the “topping out” point of construction.

The mining company is an arm of the multi-national conglomerate Komatsu. The Tokyo-based company boasts over 59,000 employees in 142 countries.

The development marks a return to the neighborhood for P&H, later known as Harnischfeger, which was founded over 136 years ago. The company made cranes, and later, mining shovels. P&H, owned by Komatsu since 2016, has spent the past 100 years just outside city limits in suburban West Milwaukee at 4400 W. National Ave.

The West Milwaukee facility and office space leased in the Honey Creek Corporate Center on Milwaukee’s west side will be vacated as part of the project.

The company hopes to have more than 1,000 employees at the site, but intends to start with approximately 600 in 2022, of which about 70 percent are expected to be office employees.

The company will occupy a 59-acre campus bisected by Union Pacific railroad tracks. The 13-acre eastern portion of the site was last owned by the city and used to store coal for the Valley Power Plant, which now burns natural gas. The site will house the office building and parking garage.

The western portion of the site was long home to Solvay Coke & Gas. An affiliate of We Energies acquired the 46-acre site in 2017 for $4 million to control the environmental costs of cleaning up the site used by one of its predecessor firms. As of 2019, it expected to spend $16 million on the cleanup. The utility is now suing American Natural Resources Co., another firm potentially liable for environmental remediation, to recover costs on the effort.

Komatsu acquired both sites in late August for $8.8 million, paying both property owners the same amount per acre.

Eppstein Uhen Architects and engineering firm GRAEF are leading the design of the campus.

The site plans call for access via E. Greenfield Ave. and S. Kinnickinnic Ave. near the Kinnickinnic River and Bay View. The roadway under the Canadian Pacific railroad bridge was lowered one foot to accommodate deliveries, similar work has not taken place on a Union Pacific-owned railroad bridge near E. Stewart St. in Bay View. At the time of approval in 2018, We Energies was scheduled to pay for that work.

In addition to road access, Komatsu will have direct railroad and water access. But port officials, as of 2019, expected the company to likely use existing port facilities across the harbor and truck the items on a circular route to South Harbor Campus.

The company, whose mining shovels are so large they leave the manufacturing facility in pieces and are assembled onsite at mines across the globe, is a regular port customer.

One of those mining shovels, as well as a truck built by another arm of Komatsu, will be on display in front of the office building. A shovel, one of the company’s older, smaller models, is currently on display at the intersection of W. National Ave. and S. Miller Park Way.

The state will provide $59.5 million in tax credits, tied to the creation of new jobs and other performance metrics. The city, leveraging incremental property tax revenue from the project, will invest $15 million in a lengthy new riverwalk segment and award up to $25 million to the company for job creation.

The city is retaining ownership of a 45-foot wide strip of land along the waterfront portion of its site that will include the riverwalk. The site could be used as a cruise ship dock in the future. We Energies will maintain ownership of the waterfront portion of its site as well as part of a liability shield.

The design submission approved by the city in 2018 envisions the possibility of substantial expansion. A 220,000-square-foot building, used for manufacturing, could be built to the south of the proposed manufacturing building. The original manufacturing building could also be directly expanded to the west with a 110,000-square-foot addition and to the east with a 51,660-square-foot addition.

A 46,200-square-foot addition to the south end of the office building is also envisioned, as well as a 27,600-square-foot penthouse. The parking structure could also be expanded.

The proposal was first introduced in September 2018.
