Services Provided
InGeo Design provided the design of excavation shoring for the main entrance and two elevation shafts, ensuring structural stability and compliance with TTC standards. Our design incorporated a combination of caisson wall, soldier pile and lagging, supported by internal bracing spanning one to three levels. Careful consideration was given to nearby building surcharges, high water table, and the sensitivity of the adjacent TTC tunnel. Moreover, our team designed and tested the micropiles to support the entrance structure, guaranteeing long-term integrity. Throughout the excavation process, we conducted field reviews, ensuring seamless project execution and adherence to design specifications.
