Roncelli was selected by DTE Energy through a qualifications-based procurement process to successfully transform their existing office space at their downtown Detroit Campus. Renovations were made to the Walker Cisler Building 21st floor and the Service Building 4th floor within an offset 12 week schedule. Immediately following the completion of this work, a second 12 week phase would begin on the Walker Cisler Building 20th floor and the Service Building 5th floor.
Both phases consisted of complete demolition and abatement of existing office areas to create a new open work station environment. This included conference and training rooms, informal collaborative space and Café area on each floor. All new building systems were provided on each floor including HVAC, plumbing, sprinkler, fire proofing, lighting, power, data, fire alarm and security.
Sound proofing of the 5th Floor Service Building was critical due to the above 6th floor Wellness Center housing a gymnasium, racquetball, and squash court and weight room. A spray on acoustical insulation was applied to the underside of the 6th floor deck and resulted in a cost savings to the owner.
Project challenges included the management of multiple, simultaneous phases of construction involving select demolition, renovations, temporary use and final use areas in a busy work environment. Great care was taken to minimize disruption to ongoing operations and building occupants.
