During construction, it was also found that the distance from the existing east abutment to the support of excavation location was much greater than shown on the contract drawings, which would require a more substantial support system. tierods, and the lower portion was braced to the existing abutment. During construction, it was also found that the distance from the existing east abutment to the support of excavation location was much greater than shown on the contract drawings, wh i c h wo u l d r e qu i r e a mo r e substantial support system. This location was also extremely close to the active tracks. The team acted quickly to provide the contractor with a bracing system connected to the portion of the existing abutment to remain that allowed the excavation to continue without delay. The support of excavation design Anchor piles adjacent to the existing rail tracks with steel tierods installed team also performed analysis and provided a design for a cantilevered soldier pile system for the excavation and construction of the new center pier for the Atlantic 6 Bridge. The support of excavation systems at the center pier and the west and east abutments performed as expected and the new bridge was successfully constructed.
