Rollins Road Gateway Construction
This week, the contractor will continue excavation for the new railroad bridge. By the end of the week, the second level of ground anchors should be installed. They will also continue removing the old Rollins Road pavement and may start with some storm sewer installation for the new Rollins.
On Saturday, March 1, the contractor is tentatively planning to drive test piles for the new bridge foundations. These piles will be H-sections, meaning their cross-section looks like a letter H, different from the sheet piles the contractor has driven to date. The contractor plans to hammer 40’ long sections into the ground, splicing on additional length as needed, until a satisfactory bearing strength is determined.
The purpose of the piles is to support the weight of the bridge and the train traffic into the soil below. The friction between the soil and the surface of the pile is what provides most of this support. If all goes well, the remaining piles for this stage of the work will be installed the weeks of March 10 and 17.
Please note that the piling operation is loud and creates vibrations as they are driven into the ground. If you notice this, please do not be alarmed; it is a normal part of this operation. If you do have any questions or concerns, please feel free to contact us.
