This was a design-built major utility project consisting of an underground 115kV cable ring interconnecting major generation and transmission centers within the San Juan metropolitan area. The project was divided into 6 different project segments, of approximately 7km each. Out of the 6 total projects, JRR furnished all of the engineering services related to 4 of these projects to Lord Electric Co. JRR performed 100% of the underground ductbank design, cable pulling calculations, cable ampacity calculations and the integration of the end-point breakers and structures into the existing utility substations. |
