Turner Construction — the firm Great Wolf relies on to build its resorts — will be tapping into area union labor to build the 500-room hotel and indoor water park in Manteca.Councilman Mike Morowit said he’s been told union workers are elated that Great Wolf is delivering on a promise that the bulk of the 1,397 construction jobs will be from the local region.The resort expected to break ground this summer will cost $180 million to build of which $76.3 million will go into the pockets of construction workers. The Great Wolf Lodge that will include a 109,767-aquare-foot indoor waterpark is expected to take 18 months to complete with a targeted opening of early 2020.And those workers with special skills that may not be available within a reasonable commute to Manteca will — like happens on other jobs — will fill Manteca hotel rooms as well as drop cash in local restaurants.That means the promised economic benefits for Manteca could start flowing as early as July.Great Wolf will employ 250 fulltime and 250 part-time workers. They intend to have a job fair first for Manteca residents with the intent to hire as many qualified candidates as they can from the community that will be home to the firm’s 19th lodge.Manteca needs tostart war on mattressesLet’s face it.
