BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with Glaus, Pyle, Schomer, Burns, and Dehaven (GPD Group) for the Jackson Pike Substation Modernization project, in an amount up to $606,664.48, for Division of Power, CIP No. 670901-100000. The work will include all engineering services for the Jackson Pike Substation Modernization project. This work will include the following:
· Specifications for the procurement of the prefabricated control building
· Geotechnical survey will be conducted to verify floodplain, soil conditions for control building foundation design, and soil resistivity
· Surveying services, preferably including a LiDAR scan of the existing substation to ensure accurate design
· A grounding system study to analyze the existing ground grid, equipment grounding, and fence grounding and design any necessary improvements like a ground test point
· Foundation Plan for the new control building
· All below grade conduit, trench, grounding, and cable design
· Structural analysis of existing steel, foundations, and required modification for strain bus additions
· Detailed schematics and wiring for all breakers, relaying and SCADA
· Relay settings developed in coordination with the City of Columbus Division of Power
· Provide an updated fault current study for the Substation

Planning Area is 59 (Southwest).

FUTURE MODIFICATION(S): It is not anticipated that there will be future renewal modifications for this project.

TIMELINE: It is estimated that design will take approximately 15 months.
