Featured Projects

Multi-Phase Wernert Center Expansion

The Thomas M. Wernert Center is a mental health recovery and support center named in honor of Tom Wernert, who was the executive director of the Lucas County Mental Health Board for 30 years until he passed away in 1999.  The 12,500-square-foot expansion of the Center by S2F Corp. included the purchase of an adjoining property, a former gas station property on Ashland Avenue., demolition, and vacating an alleyway. TTL completed a Phase I Environmental Site Assessment (ESA) a Phase II ESA, a geophysical survey to locate former nderground storage tanks (UST), an asbestos survey of the existing building, and UST removal for two potential USTs located on the property. S2F Corp approached TTL for additional work including building demolition oversight and site preparation, and hydraulic lift removal. All TTL work was completed on schedule enabling the construction activities to begin.

Wetlands Elevated Walkway Rehabilitation

TTL prepared and obtained the required 404 and 401 permits including mitigation requirements and provided oversight for the construction and repair of an elevated walkway along the Ottawa River, in a Category 3 wetland. In order to construct the elevated walkway, a temporary construction road was required within the Category 3 wetland and the flood plain of the river. The road was constructed with 900 cubic yards of temporary fill covering 0.36 acre and 450 cubic yards of temporary fill and three 72-inch diameter culverts within the Ottawa River to maintain downstream flow.
