Holloway Culvert Rehabilitation

Ballwin, Missouri

Access Engineering was the Prime Consultant for this unique culvert rehabilitation project, which was awarded the ACEC Missouri Award of Excellence and the 2015 APWA Missouri’s Technical Innovation Award.

This poured in place culvert was originally constructed in 1976.  The concrete in the culvert had experienced sever deterioration and was experiencing some undermining issues at the outfall.  The Missouri Department of Transportation gave the culvert a deficient rating, but the funding did not exist to replace the culvert with a brand new structure.  Access designed a more cost effective and sustainable solution for culvert rehabilitation. The concrete in the culvert floor had been washed away in low flow areas and the top layer of reinforcement steel was exposed. The culvert floor was rehabilitated by milling the existing bottom slab, performing surface hydro demolition, providing modified deck repairs and applying a silica fume concrete overlay.  The deteriorated portions of the roof were patched. 

The culvert outfall had failing gabion walls and the concrete outfall apron was being severely undermined due to erosion and head cutting.  The design solution included extending the concrete outfall apron to the end of the gabions and constructing a cut off wall to prevent future undermining. The gabions could not be addressed with the project dueto budget constraints, so ballast was placed under the gabions to provide additional support until funding is available.

Trestle Inspection & Maintenance Program

St. Louis, Missouri

The Trestle Inspection & Maintenance Program provides a maintenance plan for the Trestle until the build out, which will convert the freight and passenger rail service bridge to an elevated bike and pedestrian path.

Access was responsible for the inspection of the entire bridge length, from ground and aerial lift. Access determined and prioritized the repairs and maintenance activities to be conducted on the bridge. Access developed the maintenance plan in order to prioritize, design and schedule repairs.

 

BJC Forest Park Parkway over MetroLink Bridge Replacement

St. Louis, Missouri

The Washington University School of Medicine (WUSM) Campus Renewal Plan aims to improve both vehicular and pedestrian access to the campus and streetscape along Forest Park Parkway and Kingshighway Boulevard by converting the intersection into an at-grade intersection. 

Just west of Kingshighway on Forest Park Parkway, the Metrolink bridge had a sufficiency rating at 47.40 percent.  In order to eliminate the Forest Park Parkway underpass and create a four-leg, at-grade intersection, the structurally deficient Metrolink bridge needed to be reconstructed to meet the new Forest Park Parkway vertical alignment. Access Engineering was on the project team for the bridge replacement design, providing drafting support for preliminary and final design plans.  

 

Audrain County Bridges

Audrain County, Missouri

Access was on the project team assigned to the Audrain County Bridge Replacement Program, Bridge No. 55100391 over West Fork of Cuivre River on Audrain County Road 695 and Bridge No. 17200201 over Davis Creek on Audrain County Road 948. Both bridges and their corresponding roadways were designed to higher elevations to accommodate increased flow from the watershed, and widened to safely accommodate two-way traffic. Access provided design and drafting support to the team, preparing preliminary plans, right-of-way acquisition documentation, permitting documentation and final plans.
