In order to meet the time constraints, Northdale began setting the stage Friday afternoon. The guys worked on getting the 16" x 20" reducer and 20" 11 1/4 degree bend on 20" SJ WM. We bolted the reducer to 4' of 16" DIP and added 15' of 20" SJ WM, The 11 1/4 degree was bolted on a stick of 20" SJ WM. We orginally thought about using the directional drilled pipe for this work but after looking it over and the time constraits we opted for SJ and will use the directional drilled pipe in another location. On August 24th, Warning Lites set up all road closures starting at 5:30 am. Northdale's crew came in at 6:00 am to start moving boxes / sheeting closer to the intersection. We removed the bituminous pavement and hauled it to Sauters instead of stockpiling. We removed the Class 5 and stockpiled it closer so we weren't wasting time travelling to the bone yard to get material. We used our Ford Dump Truck to haul the rubble and Class 5. Reiner Contracting also came in at 6:00 am to cut the pavement on Bunker Lk Blvd. He needed to make (3) passes. Northdale started the removal as soon as he was done cutting. Once everything was removed, we dug down to find the water main and set the box / sheeting for the wet tap. Fobbe Contracting arrived around 9:45 am with two workers to perform the 16" wet tap which took approximately 3 hours that ended around 1:00 pm.They pressure tested the valve / seal also. The material was very sandy, almost like sugar sand, which required us to use all the metal sheeting that we had. It also required some fiber boards to protect the roadway from collapsing and keep the sand from running back into the trench box so we could safely lay the pipe. When Fobbe completed the wet tap, we installed the first section of pipe that included 4 ft of 16" DIP along with a 16x20 reducer and 15 ft of 20" SJ WM. We then dug out for the next pass and shifted all of the sheets. The next pipe had an 11 1/4 degree bend bolted on. We then would drag the 2nd box with us the remainder of the time and piggy backed the metal sheets. This was a slow process but was necessary to save the road from undermining and to keep the sand from coming back in. Next, we dug and installed the 20" WM underneath the utilities in the radius of the intersection which was also time consuming. It didn't make sense to stop short or underneath the (4) utilites. We would have needed to go back into the radius if we didn't. Once completed, we started to backfill and remove the sheeting / boxes. We had to work our way back to pull the first box that was installed for the wet tap. We had to be careful not to damage the existing blacktop or saw cuts. We were at the maximum width that the paver could blacktop back without making a second pass. North Oaks Paving arrived around 4:00 pm and didn't start paving until around 8:30 pm. The reason they were there at 4pm was because the plant wouldn't supply mix after 4pm so they had (4) trucks full sitting there until we were done installing the watermain. Because the depth of the bit replacement and heat, they had to pave the area in (3) 2" lifts. They ended their work around 1:00 am. While the paving was taking place, Northdale swept the intersection with our sweeper to clean all the debris from the road surface. Warning Lites pulled the detour signage around 1:00 am when the paving was completed.
