GRAND RAPIDS, Mich. – Security fences, dumpsters and hoisting cranes soon will replace ArtPrize entries around the Grand Rapids City Hall and Kent County Administration buildings at 300 Monroe Ave. NW. Project engineers have announced that heating, ventilation and air conditioning (HVAC) renovations at the buildings begin next week. The $11 million project – approved in August by the City Commission – is expected to last through early 2020.

Kyle Johnson, assistant project manager in the City’s Engineering Department, said staff and visitors at the 300 Monroe complex would notice construction activities on the exterior of City Hall and Calder Plaza consisting of security fencing, dumpster pad installation, material hoist and crane setups. He added that most of the work would go relatively unnoticed within the buildings’ three mechanical rooms.

“Due to the scope and complexity of this project, there will be multiple construction phases to minimize disruptions to daily operations,” Johnson said. “While system changeovers and highly visible events can be expected, we are committed to limiting the impact to those doing business and attending meetings at City Hall and the County Administration building.”

This is the first major overhaul to the 49-year-old buildings’ HVAC system. HVAC systems are designed to operate for 25 to 30 years based upon typical operations. Johnson said the complex’s current system was able to nearly double that timespan due to an aggressive preventative maintenance program established by the City’s Facilities Management Department. This was achieved through proactive maintenance along with specific component modifications over the past 20 years. These improvements added life but also exhausted any future modifications from taking place.

A high-level overview and estimated timeline of this 18- to 20-month project includes:

October 8, 2018:  Site preparation

  • Dumpster pad along Monroe Avenue NW
  • Safety fencing on Calder Plaza
  • Construction material hoist on south side of City Hall

 
November 2018: City Hall – 10th-floor mechanical room (Nine to 10 months)

  • Seven or more crane lifts from Monroe Avenue (Three- to five-day duration each crane setup). Monroe Avenue lane closures, including the Silver Line station, will be necessary.
  • Temporary air handlers placed on City Hall roof
  • Replacement of air handlers, cooling tower, pumps and steam system serving City Hall

 
May 2019: Monroe level – South mechanical room (Six to seven months)

  • Temporary air handlers placed in south corridor near the Kent County elevators
  • Replacement of air handlers, pumps and steam system serving the County Administration Building

 
July 2019: County Building – Plaza level perimeter heat (Three months)

  •  Furniture reconfiguration will be necessary in certain areas

 
July 2019: Monroe Level – North mechanical room (Six to seven months)

  • Replacement of air handlers, system pumps and steam system serving the Monroe level of the complex

 
August 2019: City Hall – Plaza level ceiling replacement (Three to four months)

  • Removal and replacement of exterior ceiling system
  • Replacement of heat supply below the second floor of City Hall 

 

August 2019: City Hall – Rebalance air supply (Two to three months)

  • Continuous heating/cooling will be provided as normal throughout the project
  • Contractor will visit each floor to adjust air supply to align with new air handlers and system setpoints

 
January 2020: County Building – Rebalance air supply (Two to three months)

  • Continuous heating/cooling will be provided as normal throughout the project
  • Contractor will visit each floor to adjust air supply to align with new air handlers and system set points
