Dublin City Council approved a resolution by a 6-0 vote Nov. 18 to enter into a contract and execute a guaranteed maximum price (GMP) with Ruscilli Construction Co., which is serving as construction manager at risk for renovation and construction at 5555 Perimeter Drive, the future home of Dublin City Hall.

The city purchased the property, which previously was occupied by Delta Energy, in March 2018 for $4 million.

City hall workers, including those in the city manager's office, department of finance, legislative services and City Council, will move there.

The city plans to add about 9,000 square feet to the building to house new council chambers and public meeting and office spaces. The Perimeter structure has approximately 20,000 square feet. Dublin's city hall at 5200 Emerald Parkway has approximately 22,800 square feet of floor space. The annex adjacent to city hall has approximately 3,000 square feet.

The city is moving forward on a plan dating to 1997 that envisioned the design of a municipal complex around Coffman Park, said Donna Goss, development director.

According to a Nov. 12 memo to council, the agreement with Ruscilli includes a $329,854 GMP for the first phase. The city staff plans to present an amendment to the GMP for the balance of the renovation next month and a third GMP amendment for the majority of the council chambers addition in May.

Construction of the council chambers addition is expected to be finished in spring or summer 2021, according to the memo. Work on the first phase of the renovation portion of the overall project is expected to begin in December.

The city will hold an open house and public-input session for the new council chambers from 5 to 7 p.m. Dec. 3 at 5555 Perimeter Drive.

In other business Nov. 17, council members also voted 6-0 to approve:

* A collective-bargaining agreement with the United Steelworkers of America for a bargaining unit comprising 71 employees in the public-works and parks-and-recreation departments.

The agreement includes a 2% wage increase effective Jan. 1, with subsequent increases to be determined for 2021 and 2022.

* The adoption of the city's 2020 annual operating budget.
