Project Overview
BKBM provided structural engineering services for the new 37,000-square-foot Prior Lake City Hall. The facility features lower and main levels, a partial upper level, and a mechanical penthouse, supporting the city’s administrative and community needs with modern, flexible space.
Project Highlights
- Architectural Vision:
- The design evokes sailing motifs, featuring a dramatic “wave” glass façade, a cable-braced entry vestibule, and sloped roof forms.
- The mechanical penthouse incorporates a diagonally sloped/curved roof mimicking sails for an iconic civic presence.
- Structural Systems:
- Precast planks supported by interior steel beams and columns, paired with exterior concrete masonry unit (CMU) walls for the primary building structure.
- Steel bar joists support the main roof, while steel purlins frame the complex sloped/curved penthouse roof.
- Cast-in-place and precast concrete elements deliver durability and long-term performance.
- Engineering Collaboration:
- Close coordination with the architect to realize the vision for sloped and curved steel roof systems and unique entry elements.
- Structural design ensured efficient load transfer, stability, and constructability for all architectural features.
Engineering Solutions
