We design infrastructure and commercial building improvements and provide detailed plans and specifications for use in competItive bidding.  Other services include project observation and management, septic system design, funding assistance, bike route development and master planning.  



Smolen Engineering is one of only a few engineering firms in the world with extensive experience in the lost art of designing the construction of new and rehabilitated authentic timber covered bridges for highway traffic.


Our clients are local governments, schools, healthcare, developers, port authorities, park districts, business owners and individuals.  While our reputation is national, we pride ourselves on offering, arguably, the most affordable high quality engineering  and building design services in Northeast Ohio.
