CHG Building Systems Inc. recently completed the Markey Machinery plant in South Seattle in three phases. The nearly $4.5 million project included renovation of two existing plant buildings and the construction of a new final assembly building and headquarters. CHG completed the project on time and on budget.
For phase I of the project, CHG built a 50-foot tall, 9,000-square-foot final assembly building using Memphis, Tenn.-based Varco Pruden Buildings’ pre-engineered metal products. CHG designed the building to accommodate two large bridge cranes that are used to complete assembly of Markey’s custom deck machinery and winches. In phase II, CHG built a two-story, 7,500-square-foot Varco Pruden pre-engineered building for Markey Machinery’s headquarters that includes a second floor system that gave the owners considerable flexibility with its engineering, accounting, marketing and sales offices.
In the third phase, CHG renovated two existing plant buildings, with both architectural
and structural upgrades including panel rib metal siding by Varco Pruden to match the new buildings. They replaced translucent window panels to improve interior lighting. In addition, CHG designed and built a 2,800-square-foot Varco Pruden preengineered metal crane cover for the yard adjacent to the assembly building.
According to CHG Building Systems Project Manager/Safety Director Ryan Grouws, the metal buildings were chosen, with the input of the owner, for their durability in an industrial use, upgrading the facility in a cost effective way.
“Metal buildings are the best type for this industrial use,” Grouws said.
According to Grouws, the Varco Pruden metal panels on the existing building were chosen for color and profile to match the newly built metal buildings on the site. The metal panels were attached to the existing wood frame, covering the existing corrugated metal siding with a new metal skin.
“Once the owners decided on metal buildings, we chose CHG to help with the design
development,” said Leon Cohen of General Consulting Services Inc., the owner’s representative for the project. “They were able to meet the budget and completed each phase within budget as well as offering design and constructability improvements throughout the process. This was the first major renovation to the 75-year-old facility, and it increases capacity, as well as cost efficiency.”
Markey Machinery was founded in 1907 and designs and manufactures high quality custom deck machinery for workboat, scientific and dockside applications. Founded in 1987, CHG is a family owned company that provides pre-engineered metal buildings, structural steel, architectural sheet metal, seismic retrofitting and retrofit roof systems throughout the western U.S., Alaska and Hawaii.
