The Johns Creek City Council has approved construction manager’s and architect’s contracts for its new city hall, to be created in an existing office building at 11360 Lakefield Drive.

The council awarded a construction manager at-risk contract to Balfour Beatty Construction. Its contract is 3.25 percent of construction costs, a guaranteed maximum price not to exceed $423,000, and $576,000 for general conditions, a Johns Creek spokesman said. (“General conditions” is a fixed amount covering pre-construction services and costs of tools, equipment and resources, staff said.)

Clark Patterson Lee was awarded the architectural services contract — 5.95 percent of construction costs for basic design services not to exceed $774,000, the spokesman said.

The project now enters the pre-construction phase, with demolition starting while construction documents are finalized, according to a staff report to the council. No construction will begin until a guaranteed maximum price is committed to by Balfour Beatty and approved by the City Council, expected next May.
