Last week, Teichert Construction completed the deck pour of the Brushy Creek bridge, a milestone event. The concrete deck pour took place at 4 am to minimize the affects of the wind and heat on the concrete itself. Conducting the deck pour prior to the morning commute hours also minimizes the travel time for concrete trucks transporting the material from the plant to the project site. Prior to the deck pour itself, a bidwell was installed on temporary railings supported by the deck forms. Traveling above the deck on rails, the bidwell evenly spreads the concrete (pumped onto the deck in separate operation) to create the final road surface. The temporary rail system and bidwell ensure that the final deck grades are constructed to the designed road grades.
Teichert Construction spreads the concrete prior to the bidwell screeding the concrete to the deck grade
The bidwell passes over the concrete. The auger in the front collects and spreads the concrete while the roller and finish pads ensure the correct grade is formed.
Concrete is pumped directly onto the deck in advance of the bidwell.
After the bidwell passes over the concrete, finishers spray curing compound from a catwalk.
County Inspection Staff test the concrete material properties onsite to ensure quality assurance.
