The goal, officials said, is to modernize plan review while maintaining local oversight. E-Plan Exam provides outsourced electronic reviews for commercial building plans, including structural, HVAC, plumbing, fire alarm and fire sprinkler systems. Plans are submitted digitally, reviewed by registered engineers and returned with comments more quickly than through the traditional state review process. I can do plan reviews only up to a certain size. In Door and Kewaunee counties, municipalities such as Sister Bay, Sturgeon Bay and Sevastopol are among those that have adopted E-Plan Exam review tools.
