NOTES:

1. Construction costs are based on May 2026 values and include escalation based upon a midpoint of construction to July 2028.

2. This Statement of Probable Cost is based on current level of documentation available which is a visual observation of current facilities. Estimates are developed on reasonable best efforts to assess geographic considerations, assumed building type, construction methods, current labor rates and material costs, and local market conditions to generate an opinion of possible project specific costs. Adjustments to this estimate could produce amendments to subsequent and future project budget updates based upon changes in project specific requirements, program refinement or unforeseen adjustments in local market conditions affecting both direct and indirect costs.
