The project has encountered some recent challenges that have impacted the schedule. The challenges are associated with the Contractor’s ability to place concrete due to a cement shortage within the concrete industry and an unseasonably cold November. The remaining key project tasks (bridge deck, sidewalk and parapet) associated with the east bridge over the Fox River rely on the ability to pour concrete. The Contractor has been working diligently to avoid further problems related to the cement shortage. The Contractor plans to proceed with placing concrete for the remaining items when
The new east bridge deck over the Fox River is framed and reinforcement steel is being installed in preparation to pour the concrete structure. The east bridge deck will contain over 140,000 pounds of reinforcement steel. Following the bridge deck pour will be the installation of the approach pavement (transition of pavement between the bridge deck and the roadway), 7' sidewalks along the bridge and decorative bridge railing.
D Construction completed replacing all of the existing beam bearings at abutment and pier locations for the east bridge over the Fox River. The existing beams have been lowered down on the new bearings and all new structural steel beams have been set in their final positions. As all of the substructure components have been completed, the Contractor has started framing and form work for a new widened concrete bridge deck. Once D Construction completes the bridge deck form work, reinforcement steel will be installed and the deck will be ready to be poured.
D Construction has lifted the existing beams and started bearing replacement work on the east bridge over the Fox River. The beams are lifted using hydraulic jacks, and they remain lifted until the Contractor is able to remove the old bearings, pour new concrete seats and set replacement bearings. To date, the Contactor has removed and replaced 75% of the bearings on the east bridge. Bearings are located at the connection points of the beams and the supporting surfaces at the piers and abutments. Bearings are intended to control movement and reduce stresses.
The new steel beams have been set and the existing concrete deck was removed for the East bridge over the Fox River. The new steel beams are located on the widened concrete piers and abutments. The new steel beams will support the new concrete bridge deck, which will be wider than the existing deck. Following the placement of the new beams, the Contractor removed the existing concrete bridge deck. Now that the bridge deck is removed, D Construction can work on jacking up the existing beams at the abutment and pier locations. The beam jacking is necessary so that the existing beam supp
