Brushy Creek Bridge Deck Pour

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.

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.

Soil Nail Wall 7 Excavation

Teichert Construction began excavation operations last week for Soil Nail Wall 7, located at the northern project limit. The existing hillside excavation consists of removing occasional sandstone and cemented rock formations. In addition to excavators and blade equipment, Teichert Construction is using breakers to chip and remove the bedrock material. After each "lift" is excavated, soil nails are installed to secure the hillside followed by the shotcrete wall facing.

Soldier Pile Wall Work Continues

Teichert Construction has completed a signifcant portion of the soldier pile retaining walls required for the road widening at the southern project limit. Steel piles were installed and cast in concrete holes along the hillside. Teichert Construction crews then excavated the hillside and installed timber lagging to retain the hillside slope. A concrete facing wall be installed in front of the timber wall with an architectural finish in the following months.

Teichert Construction removes "lean" concrete and soil around the piles to install timber lagging.

Bridge Work Continues

In the last month, Teichert Construction has made significant process in completing the construction of the Brushy Creek bridge widening. Wood form work for the bridge structure was erected and steel reinforcing bars installed. The "stems and soffit" of the bridge structure was poured with only the main deck pour remaining.
