550 William Mixed Use

75,000 square foot mixed use apartment building

Immel Construction served as Construction Manager for 550 William, a five-story mixed-use development bringing upscale residential living and commercial space to the heart of De Pere. Designed to complement an active downtown lifestyle, the development places residents within walking distance of restaurants, entertainment, and the Fox River. The property features 60 apartment units with high-end finishes and approximately 6,000 square feet of flexible retail and commercial space.

Description

The building utilizes a “4-over-1” podium-style design, combining precast concrete columns, beams, and planks at the podium level with wood-frame construction above. Masonry, brick, and metal siding create a contemporary exterior suited to its prominent downtown setting, while design-build mechanical, electrical, and plumbing systems supported an efficient and coordinated construction approach.

Engaged early in the project, Immel worked collaboratively with the owner and architect throughout design to provide constructability reviews, conceptual estimating, value engineering, scheduling, and logistics planning. Immel’s preconstruction guidance identified $1.5 million in value engineering and cost-saving opportunities, helping maintain the project’s vision and quality while aligning with the owner’s budget.
