Once the City contractor a consultant to provide construction management has completed jack and bore, the SA-7 PRS and inspection services to oversee three construction can begin; however, cannot be fully interconnected projects within the SR-55/Ritchey completed until the Caltrans contractor completes Water Improvement Project with the goal to relocate a water main, a pressure reducing station, and the months. water pipes crossing under the SR-55 in advance Although it is important to get the contractor of the highly anticipated SR-55 widening between mobilized to complete the Ritchey St work, critical the I-405 and I-5. The Berg team values working on projects that enhance connectivity, safety, and the bore and jack operation and the SA-7 PRS infrastructure upgrades within communities. construction dependent upon the initial right of way waiting period for RICOH. This affects the easterly and knowledge that Berg has specialized in for pit and the waiting period for the Caltrans RCB, 40 years in the Southern California region. The which affects completion of some minor aspects main construction elements include excavation/ of the PRS. A suggestion would be to have 2 interim milestones: one for the completion and installation (PVC, DIP, welded steel), water activation of the Ritchey St main and a second for monitoring/control systems, water systems the activation of the SA-7 PRS. This would ensure the primary objectives of the Project are met as quickly as possible.
