These unit costs will be updated in future estimates after further evaluation by the Design Team.Expected premium for structured concrete foundation. Possibly not required. Dependant on Geotech Report.Represents estimated IT cost of $125K + Security cost of $75K. Based on ROM Estimate from DataCom Design Group."Assumed Current Cost" is the $220/SF unit cost used in the previous Needs Assessment to represent the projected building cost. This amount was used to represent End of Year 2013 fully finished basic building construction before "Infrastructure Costs". The value of $154.00/SF found in column "2" is 70% of the $220.00/SF and represents the projected cost to constuct unfinished shell space.Based on R.S. Means, Square Foot Costs, 2015. Means costs are escalated to January 1, 2015.Used same cost from Needs Assessment estimate.
