Project Details
Banner surveyed the project area, created a hydraulic model, sized structure alternatives, met with the owner and DOT for the TS&L meeting, designed the structure, performed a load rating, prepared the construction documents/plans, reviewed shop drawings, provided on site construction observation, coordinated testing, and provided updates to clients.
The structure is a double barrel 11' x 9' cast-in-place box culvert over North Buffalo Creek located on County Road 21 south of Lake Madison in Lake County, SD. The structure design consisted of the top slab, walls, bottom slab and wingwalls using Eriksson Culvert software. A structure load rating was performed using AASHTOWare BrR. Banner created construction documents/plans following DOT format.
For construction administration, Banner reviewed construction submittals including concrete mix design, girder shop drawings, and other materials to ensure the products met the planned requirements and specifications. Banner was on-site to monitor job progress was within specification limits, advise the contractor and project engineer of nonconformance, coordinate material sampling and testing, measure quantities for payment, and assist with the pay applications. Personnel responsible for construction observation have received certified training in accordance with the SDDOT Materials Testing & Inspection Certification Program Manual. Banner communicates progress with the owner throughout construction.
