This ordinance authorizes the Director of Public Utilities to modify and increase the contract with GPD Group for professional engineering services during construction for the 69-2 Circuit Improvements Project (CIP #670608-100015). The project involves upgrading a 9.7-mile, 50-year-old transmission circuit from Southerly Substation to Jackson Pike Substation, with 8.3 miles needing reconductoring. The scope includes project management, field survey, detailed design, construction drawings, permits, engineering services during construction, and record plan drawings. An assessment of existing infrastructure (poles, lightning arrestors) will also be performed to meet NESC requirements. This is the first of two planned contract modifications to add funding for continued work, increasing the contract by $1,153,133.82. The total contract value will be $3,679,413.85. The project spans across "64 - Far South", "63 - South Side", and "59 - Southwest" Columbus Communities.
