Informing the Public. With an adjacent daycare area on the north side, we are aware of the attention required to protect the public and secure the construction site every night. From previous projects constructed in similar environments, we have learned the key to success is to keep the surrounding residences informed of our activities and to maintain the schedule as discussed. Schedule and Work Task Understanding Once awarded the project, we will begin pursuing the pre- construction activities, including the job- specific QC plan, the MOT plan, temporary structures design, shop drawings and the procurement of materials. We employ a full -time PE to develop and stamp temporary designs as required. As a part of our quality program, we maintain an engineer at the pre -cast yard to perform quality audits on permanent materials before they are shipped to the project. Following NTP, erosion control, MOT installation, and clearing and grubbing, the soil mixing operation will be the first permanent work installed. Since this operation will disrupt entire access to the bridge, it must take place first so that access to the structure will be clear. Soil is excavated to 1 ft. above the water table for wet mixing. Traditionally, a batch plant would be installed on site during construction; but, due to the tight areas, the soil mixing operation will employ ready mix trucks from a local concrete plant. The mixing operation will take approximately two weeks to complete both sides with two additional weeks of cure time. A cone penetrometer will be used to test the shear strength of the soil before it can be loaded. Next, a temporary bridge or trestle will be built to allow for drilled shaft and crane access to the water. The trestle on the south side will be built up to bent 4, and from the north side will be built south to bent 5. The trestle will allow the augers to drill and pour the shafts during construction. Plus, vacuum trucks will be employed during shaft construction to keep shaft slurry from entering the water. L L. L L 7i.
