SME provides multiservice engineering and consulting to developers, municipalities, owners, and power companies in the solar array industry. One such example is the DTE Energy Demille and Turrill Arrays.

SME’s work on the Demille and Turrill Arrays occurred in two locations and times:

BARTON MALOW – TURRILL ARRAY

During March of 2017, construction of a solar array for DTE Energy was well underway; however, the site topography had been rolling with significant overall elevation changes. Barton Malow, DTE’s construction advisor, retained SME to provide stormwater and soil erosion control design services. SME conducted a topographic survey of the 193-acre property, hand collected shallow subsurface borings for evaluation, prepared engineering documents of our recommended design, and provided Construction Administration services that included field verification and materials testing.

DTE ENERGY – DEMILLE ARRAY

DTE Energy, in collaboration with the City of Lapeer, broke ground in the spring of 2016 on 45 megawatts of new solar generating capacity at the DeMille Road project site. Completed in 2017 by construction manager Barton Malow, the array generates enough clean solar energy to power more than 4,500 homes. Barton Malow selected SME to provide pavement engineering services that included subgrade stabilization and design recommendations for the construction of the access roadway for the site. SME identified the existing conditions of subgrade soils at the site and provided recommendations for soil stabilization to provide a subgrade that would support the proposed pavement system. The proposed roadway was designed to include approximately four inches of aggregate base over a chemically stabilized subgrade.
