(SCC) was in the process of advancing the lift station excavation (Picture 1). At the time of my arrival the excavation had been advance to approximately 3 feet above final grade and was being shored with a combination of trench boxes and steel sheets. Standing water was present in the excavation and located at approximately 5 to 7 feet below ground surface. The exposed soils appeared to consist of a surface layer of black fine grained organic material that was underlain by light brown recessional sands and gravels. SCC had removed a large portion of the surface organic material from the site prior to my arrival (Picture 2). -Prior to my arrival SCC had fabricated a pair of 2 foot diameter approximately 20 feet long pieces of pipe that they planned to use as sump pits in the de -watering effort (Picture 3). Jay Brown, of SCC, indicated that they planned to set these two sump pits into the western portion of the excavation and pump the water from the excavation into a settling tank. The settling tank was located on the western comer of the site and consisted of a cylindrical tank that had been cut in half and had several baffles installed (Picture 4). It appeared as if the water from the excavation was to be pumped into one end of the baffled tank and discharged out the other side. -Shortly after arriving on site SCC began attempting to place a second large trench box on top of the already submerged one (Picture 5). After checking to make sure the trench box fit SCC removed the box and continued to excavate in the wet (Picture 6). The soils excavated from the base of the excavation consisted predominantly sandy gravel consistent with the gradation expected of recessional outwash. -While I was onsite, SCC received delivery of two dump trucks and pups containing 2 to 4 inch quarry spalls (Picture 7). Once the spalls were delivered these trucks were used to transport excavated soils off site for disposal. SCC proceeded to fill the void between the steel sheets and the edge of the excavation with the spalls while I was on site (Picture 8).

Shoreline Construction Co. Jay Brown Donald J. Hulin -SCC completed the excavation at approximately 1:30 PM. Upon completion SCC proceeded to place the two sump pits in the western edge of the excavation (Picture 9). These sump pits were installed approximately 1 to 2 feet below the elevation of the proposed foundation gravel. At approximately 2:00 PM a truck and pup of pea gravel was delivered to the project site. Once in place the exterior of each sump pit was backfilled with spalls and pea gravel (Picture 10). -At approximately 2:30 PM I departed the project site. Jay Brown of SCC indicated that they planned to complete installation of the de -watering system today. He also indicated that they were not planning to start de - watering until Saturday of Monday.

(SCC) was actively de - watering the lift station excavation (Picture 1). At the time of my arrival two 6 inch submersible pumps were being used to remove water from the excavation. This water was being pumped to a settling tank located along the western edge of the project site (Picture 2). Shortly after I arrived, SCC recorded elevation of the base of the excavation as well as the elevation of the water in the excavation (Picture 3). Based on these readings SCC indicated that the elevation of the base of the excavation varied across the excavation and that the standing water was located almost exactly at the base of the proposed structure (Picture 4). -As I arrived on site I observed that 1481h Avenue SE was closed to traffic just to the north of the project site due to flooding over the roadway (Picture 5). -At approximately 11:00 AM SCC disconnected their de -watering system in order to allow for installation of another trench box. After disconnecting the de -watering system, the trench box was lowered into position with the Komatsu 400 excavator (Picture 6). Once the final trench box was placed and the de -watering system was reconnected, SCC began excavating soils from the base of the excavation (Picture 7). This soil was removed from the comers of the excavation in an attempt to provide a level base prior to placing rock. Approximately 4 bucket loads were removed in this effort. -Once the excavation was advanced to the desired depth approximately 1 foot of standing water was still present. Therefore, SCC placed between 6 inches and 1 foot of 2 to 4 inch Quarry Spalls throughout the base of the excavation (Picture 8). The thickest placement of Quarry Spalls was near the middle of the excavation. Directly after placing the Quarry Spalls SCC compacted this material by tamping it with the Komatsu 400 bucket several times. -At approximately 12:30 PM two loads of Pea Gravel were delivered to the project site (Picture 9). Once delivered this Pea Gravel was placed over the top of the already placed Quarry Spalls. Once these two truck loads of Pea Gravel were placed across the base of the excavation a laborer entered the excavation to distribute the material evenly by hand.

Shoreline Construction Co. Jay Brown Donald J. Hulin -At approximately the same time as SCC's laborer entered the excavation the water level in the excavation began to raise slightly (Picture 10). From approximately 1:00 to 2:00 PM SCC tried various pump configurations in an attempt to draw down the water in the excavation. Ultimately, the water was drawn down through the utilization of two 6 inch pumps (one located in each sump pit), two 2 inch pumps (each pumping water from the base of the excavation into the sump pits), and one three inch pump (pumping water from the base of the excavation out and into the settling tank). At approximately 2:00 PM the majority of the water had been pumped from the base of the excavation and the Pea Gravel was leveled (Picture 11). -Prior to my departure from the project site SCC indicated that they were going to place 1 more truck load of Pea Gravel in the excavation to finish leveling the base of the excavation. Furthermore, SCC indicated that they planned to set the proposed structure on Wednesday the 15th of December. -While I was onsite I did not observe any signs of potential excavation instability.

The excavation was covered with two large steel sheets to prevent anyone from accidentally falling into the excavation (Picture I).

(SCC) was receiving delivery of components of the lift station structure (Picture 1). Upon arrival I observed a Krupp crain was set up to the east of the lift station excavation (Picture 2). This crain was to be used to lower the sections of the lift station into the excavation. -Prior to SCC placing the first section of the lift station structure I observed that SCC had finished leveling the base of the excavation with Pea Gravel. I observed that a small amount of standing water (approximately %2 to and inch) was present at the base of the excavation. The de -watering system was continuing to function properly and was discharging into the onsite settlement tank. -At approximately 11:10 AM SCC began placing the base of the lift station structure (Picture 3). Once in place the structure was leveled and surveyed for elevation (Picture 4). Based on my observations the base of the structure appeared to be resting uniformly on the Pea Gravel bearing pad. -Prior to departing the project site I mentioned to Erik Waligorski, of Roth Hill, that the contractor should take special care when removing the two sump pits from the excavation. These pits are currently installed to a depth below the base of the structure and are surrounded by a backfill consisting of a combination of Pea Gravel and Quarry Spalls. Given the close proximity of these sump pits to the edge of the structure (Picture 5) it is possible that some of the foundation Pea Gravel, located below the western edge of the structure, could run out from under the foundation and into the void created during removal of the sump pit. To mitigate this effect it may be beneficial to backfill around and inside the sump pits (up to 3 to 4 feet above the base of the structure) with Pea Gravel prior to placing standard backfill material. Placement of this material both inside and outside of the sump pits would reduce the potential for void generation during sump pit removal.
