The project involved design of a new Maintenance Facility on 10-acre site. Foppe was contracted with the Ohio Department of Administrative Services to provide a topographic survey, a geotechnical investigation with report, and civil engineering site design.

There were a number of issues that complicated this site. The main issue involved coordination with the existing hospital, which had two buildings on the site, and was in the process of designing an addition to the hospital. FOPPE coordinated the detention calculations for the new ODOT site with the hospital work, so that one detention basin will be used for both sites. FOPPE also coordinated the timing of the basin construction with the local authorities, obtaining approvals to delay the basin construction until after the ODOT site is completed and the hospital site is under construction.

The main road in front of the site was under construction during the length of the design work. FOPPE combined the on site survey with the new roadway plans to produce a base plan which could not be completely surveyed on site.

An existing combined sewer was located on site. FOPPE worked with ODAS to re-align the proposed buildings so as to not have to relocate these lines. FOPPE also worked with the local sanitary authority, Metropolitan Sewer District, to disconnect storm flows from the sanitary network and provide for future sanitary services.

After reviewing the preliminary site plan proposed by ODAS, FOPPE made recommendations to revise the site layout and grading to allow the use of an existing drive for traffic and lay-down area, instead of abandoning this existing feature.

This site had numerous trees which ODAS was trying to save. FOPPE's survey located these and the site plan and grading was revised to save as many of these as possible.

This is the first site that ODOT will be using a special decanting structure to catch pollutants from ditch dredging and vacuuming operations. FOPPE investigated the possible contaminates that are in this type of material and provided a unique design to capture and filter these pollutants before being outletted to the stream.
