Whether it’s a standard cast-in-place standard box design or proprietary precast system, CFS will determine and execute the most suitable design and construction approach. As labor cost continues to rise, so do cast-in-place reinforced concrete options. CFS has worked on many precast box culvert projects to cut costs and increase speed of delivery, reducing traffic delays and rerouting time. We utilize the latest in structural analysis design tools to work quickly through numerous geometries, loading conditions, river elevations, and utility coordinations to determine the most practical design based on the design forces present.


Missouri Route O 
Scott County, Missouri

Route O we designed a triple 15’x8’ reinforced concrete box culvert to replace the existing 73’-8” three span concrete channel beam structure. This design maintains the existing hydraulic properties of the channel while decreasing the long term maintenance cost of the structure.

CFS was responsible for the design, plans, cost estimates and job special provisions for two structures in Southwest Missouri over local drainage ditches. CFS prepared preliminary bridge plans, hydraulic design,and final bridge PS&E.

South Liberty Road Low Water Crossing 
Cole County, Missouri

CFS was selected by Cole County to address a low water crossing on South Liberty Road near Taos, Missouri. The crossing was replaced with a triple box culvert. A portion of the adjacent roadway was redesigned to remove a curve in the roadway to improve sight distance. CFS completed a hydraulic analysis for the waterway to determine the type and size of structure. CFS completed topographic and boundary surveys of the area, geotechnical borings, preliminary plans, right-of-way plans, legal descriptions, final plans, specifications, cost estimates and job special provisions.

"CFS Engineers completed P.S.&E on a project to replace a low water crossing with a bridge structure. They analyzed options and as a team we chose a triple cell box culvert. The project also included some roadway realignment. CFS Engineers was very good to work with. They were very professional throughout the whole project. The completed project came in well under budget."
