Northwestern Medicine Grayslake Outpatient Center MOB Addition

As the civil engineering consultant, Eriksson Engineering Associates, Ltd. (EEA) supported Anderson Mikos Architects in the 3-story, 90,000 sf Medical Office Building (MOB) addition to Northwestern Medicine Grayslake Outpatient Care Center in Grayslake, Illinois.

EEA’s professional civil engineering services included
on-site elements, such as:

• site demolition, site paving & geometry, site concrete and modular paving,
• excavation and grading, finished grading,
• erosion control measures,
• Stormwater management and Pollution Prevention Plan,
• sanitary sewer service line,
• water service line and water main relocation.

The expansion has afforded local residents more convenient access to high-quality care. Northwestern Medicine Grayslake opened the center to provide added convenience patients living in western Lake County. The MOB addition project included the relocation and expansion of the campus storm water detention basins and protection of existing wetlands. The stormwater detention basin was designed as a naturalized wetland and open water feature. The parking lot included green engineering practices such as bio-infiltration swales and permeable pavers.

The approval process through the Village of Grayslake was complex due to the existing PUD constraints. The design and ownership teams worked in concert to address all village issues and requirements, while maintaining the desired scope and vision of the project. EEA worked with the county utility agency relative to sanitary sewer and water supply connection fees and saved the client over $150,000 in the process.

The project was awarded Leadership in Energy and Environmental Design (LEED) Silver status by the U.S. Green Building Council.
