Roncelli was selected to perform the window replacement program for DTE Energy at their downtown Service Building located at One Energy Plaza Drive, Detroit, Michigan.

The project involved the replacement of 24,000 SF of 1930’s era windows and glass block with 1,024 new double-pane insulated glass units and included related work such as environmental remediation, lintel refinishing, rough and finished carpentry, plaster patching, painting of office walls and window treatments. Work also included the replacement of a curtain wall entry system including new prefinished metal soffits above the entry.

The installation required the use of movable partitions, swing stages and hydro-lifts to efficiently perform demolition and installation while ensuring safe progress throughout the project including maintaining safe access and passage for pedestrian and vehicle traffic on all sides of the building. The five month schedule incorporated two shifts of work per day with select demolition and removals during non-office hours. Sequencing was driven by DTE’s requirement of displacing a maximum of twenty-five workstations at any given time.

Roncelli has proven success in working closely with its customers to coordinate interior fit-out and work place transformation construction activity within occupied spaces to minimize the impact to occupants. For the window replacement project, Roncelli worked closely with DTE Energy members and Service Building managers to sequence work that included phased construction activities in completing the demolition and installation and minimize impact to Service Building tenants and ongoing operations.

Completed in 1938, the Service Building stands at 6 floors and supports DTE Energy’s customer service, technology initiatives, corporate functions and employee wellness including a gymnasium and work-out areas.
