The DOI modernization is a six-phase occupied Federal Government office building renovation that began just prior to September 11, 2001. Grunley’s work is more than 75% complete. The overall project is sequenced from the north end, wing 6, to the south end, wing 1, and the work flow is generally from the top of the building to the bottom. We are currently working in wing 2, which is scheduled to be completed in September 2011.
Current Status:
In the interior of the building, Grunley is substantially complete with demolition, hazmat abatement, and rough-in of new MEP systems. Final paint and finishes are being completed on floors seven through four. In the restrooms, ceramic tile and toilet fixture installation is ongoing, with the toilet partitions scheduled to arrive on site shortly. The emergency egress stairs on both the East and West sides are installed down to the first floor and basement, respectively, together with the newel posts and handrails. On the lower floors, including at the stairs, wall and ceiling close-ins are swiftly being completed.
In addition to the interior renovations for Wing 2, Option 4, Grunley was awarded additional scope at the exterior of the building under the American Recovery and Reinvestment Act. The exterior projects include:
- Bollard Replacement
- Guard Booth Replacement
- Waterproofing
- Façade Repairs
- Green Roof Installation
To date, Grunley has installed new guard booths and bollards at two of the scheduled six ramps. Currently, waterproofing and new structural elements are being installed at the third ramp. Façade cleaning and repairs have commenced at Wing 6.
What’s Next?
- Finishes on floors four through one, including: casework, painting, carpet, resilient flooring, light fixtures, installing doors, and hardware.
- The material hoists, debris chutes, and scaffold back structures are scheduled to be removed shortly in preparation for site work to begin.
- Rough-in of MEP systems and build back work at the specialty finish areas of floor 1 - DOI Museum and Native American Indian Gift Shop.
- Child Care Center: Design documents for the new childcare space have been obtained but the final scope is still being finalized. The work is scheduled to commence in June.
- Green Roof: The existing roofing at each Wing of the building will be replaced with new “green roofs.” The demolition for this work is scheduled to begin shortly.
