Project Overview
BKBM provided civil engineering services for the replacement of two primary campus creek culverts at Bethel University. The goal was to address a critical infrastructure failure, restore the site safely, and enhance recreational and pedestrian amenities for the campus community.
Project Highlights
- Culvert Replacement:
- Removal of failed, collapsed corrugated metal pipes that routed a significant creek through campus
- Installation of two new 72-inch reinforced concrete pipe culverts to provide long-term reliability and capacity
- Site Restoration & Sidewalk Improvements:
- Removal and full replacement of the main campus sidewalk, which ran above the affected culverts
- Heated concrete sidewalk placed on 2-inch insulation with a sand base and drain tile beneath, reducing frost heave risk in clayey soils and ensuring year-round accessibility
- Complex Water Management:
- Temporary pump and bypass system installed upstream to reroute creek flow around the project area and into Lake Valentine
- System required multiple adjustments due to frequent water level fluctuations and adverse weather, ensuring continuous site dewatering
Engineering Solutions
BKBM’s civil team prioritized safety, durability, and resilience. The new reinforced concrete pipes provide robust, maintenance-friendly water conveyance, while the innovative heated walk and drainage assembly protect against seasonal freeze-thaw cycles. Active water management ensured on-time delivery even under fluctuating hydrologic conditions.
Results & Impact
Project completion restored vital campus infrastructure, eliminated a dangerous sinkhole, and enhanced pedestrian connectivity. The newly regraded and restored lawn area now serves as a safe and functional recreational space for students, supporting campus life and events. BKBM delivered a resilient, long-term solution—on schedule, even in the face of challenging weather and water conditions.
