construction cost valued at $20,000,000 or more may be bid
using the single prime delivery method at the discretion of
the public institution of higher education.
With respect to any construction project described in this
subsection (a-5), the public institution of higher education shall: (i) specify in writing as a public record that the
project shall comply with the Business Enterprise for
