Duquesne Light Company awarded a contract to PDDM Solutions to provide professional consulting to determine the feasibility and constructability to either replace or stabilize several existing transmission towers near the Carson Street Substation. The scope of services required the evaluation and constructability review to access and determine a feasible approach to either remove several existing transmission line lattice towers that were located in slip prone areas that had experienced recent earthen cracks and slides or stabilize the surrounding areas to prevent any additional movement.

The constructability/feasibility study was required to determine the best method for constructing access to the existing transmission towers, required laydown areas, and other requirements for each option proposed in order to proceed forward in the proposed approach and develop the design drawings and contract documents.  In addition to the constructability/feasibility reviews, our services extended to developing project budgets and proposed schedules based upon estimated durations for construction and restoration.
