Report on expansion needs,
infrastructure evaluation, and ADA adaptation
The library needed to expand approximately 50%, lacked ADA compliance, and
the mechanical systems were not energy efficient. The city required an
analysis for future functional operation of its facility.
The library's need for expansion was restricted to vertical development, as
the current structure filled the entire site. The existing mechanical
systems lacked appropriate maintenance. There was also an extensive lack of
The structural engineer's evaluation determined that the existing structure
could not accommodate additional floor loads. A costly structural system
would require additional new columns and sub surface foundations to support
Professional engineers determined that the existing mechanical systems --
which consisted of the original equipment -- represented the lesser-quality
manufacturers, as well as poor installation. Modernization would require
replacement of all related parts and equipment.
Code evaluation of ADA requirements demonstrated there was no compliance for
the entrance access, level changes, washrooms usage, and corridors usage.
These corrections would entail major modifications because of placements of
washrooms adjacent to structural bearing walls, extensive level changes, and
corridors against building mechanical spaces.
Cost analysis demonstrated that the required modification were major and the
remaining architectural spaces are static, lacking flexibility for the
future growth of this multi-disciplinary library.
The report justified the need for a new facility, which the City of Evanston
sanctioned and authorized an international competition for a new Main
