The fast-tracked work toward a new Forsyth County courthouse and expanded detention center continued Wednesday with the initial meeting of the project manager selection committee.The committee received proposals from five firms to review and rate based on the criteria the county requested. Four Atlanta firms — Heery International, Jacobs, Gleeds and JLL+CPS — as well as Carter Goble Lee of Alpharetta — submitted proposals to manage the courthouse and jail construction projects, which voters approved through a 1-cent sales tax extension in the fall.The next round of the special purpose local option sales tax, SPLOST VII, includes an estimated $100 million for the jail and courthouse, to be built across from each other on East Maple Street in downtown Cumming.Officials have said current estimates project the new round of sales tax will bring in about $203 million through July 2019.In addition, voters approved the bonding of up to about $89 million for the projects’ initial start before sales tax revenues are collected beginning in 2013.The five-member group will meet again on June 19 to compile the scores and recommend a list of firms that qualify for a bid.
