The Plymouth County board of supervisors signed a contract with Professional Consulting Services for $310,000 to manage construction of the law enforcement center which includes the county's new jail. Brian Gibson of PCS, who has been working on the planning stages of the project noted in a letter to the supervisors several advantages to the contract. The consultant would manage the bidding process in such a way that could make sure the winner bid showed experience related to jail construction. Without a project manager, the contractor would be granted an additional 15 percent toward construction, according to industry practice. The PCS management contract was approved by all five supervisors at a cost of $310,000. Earlier this month, supervisors signed a contract with Moore and Associates architectural firm for $267,000. Supervisor Jim Kestner reminded his fellow board members that both costs had been included in the $5.4 million total for the law enforcement center.
