NC Dept of Admin is advertising for designers/planners for a “Archdale Building Renovation – Feasibility/Planning Study”
also… that last sentence 
As of 2022 the windows, plumbing, HVAC, electrical, sprinkler, communication and interior systems of the Archdale building are 45 years old and the building is in need of a major scheduled renovation. At 242,647 sq ft, the building houses multiple government agencies and will require the relocation of all staff to leased space while the building is brought off-line for renovation. Renovation cost of similar space indicates expense can approach $100 million.
The complexities of renovating this building include, a very tight triangular site bounded by major roads and an underground parking deck. The 16 story building lacks windows on the major sides of the building which has been a source of complaint by all occupants and by many government officials. A study is needed to evaluate the major implications of replacing/modifying/renovating the building envelope including roofing, cladding and interiors or demolition of the building.
A reasonable planning effort to fully evaluate the options will require the involvement of a designer experienced in High-rise renovations, Structural engineer for system analysis, HVAC, Plumbing and Electrical engineers to evaluate options, civil engineer to evaluate site for crane work and utility work, Demolition specialist to evaluate cost of deconstruction as implosion appears to be impractical.
