1.1 Project Name: Jackson Pike Substation Subsurface Investigation Capital Improvement Project No: 670901-100002 1.2 Project Overview: The Department of Public Utilities (DPU), Division of Power (DOP) is soliciting detailed technical proposals from experienced professional consulting firms to provide subsurface engineering services for the Jackson Pike electric substation facility located at 2500 Jackson Pike, Columbus, OH 43223. The design of a capital improvement project to modernize the Jackson Pike substation was suspended when preliminary field investigations indicated the potential presence of subsurface void(s) indicative of Karst features. These findings raised concerns about the structural stability of the substation infrastructure. The potential risk of ground subsidence and the resulting damage to critical electrical components necessitates a thorough investigation to accurately identify and address these subsurface conditions before proceeding with any further improvements at the substation. This subsurface investigation project focuses on verifying the presence and extent of the suspected Karst features and developing any necessary mitigation strategies to ensure the long-term integrity and reliability of the substation. The City reserves the right to cancel this RFP and reject any bid or proposal, in whole or in part, for good cause when it is in the best interests of the City. In the event of a contract, if the project is delayed for any reason by the City, the City may request to modify the contract to reduce the maximum final obligation of the contract to a minimal level until the project resumes. When the project is intended to resume, the contract will be modified to increase the maximum final obligation to the contract amount necessary to fulfill the remaining services needed. 1.2 References: 1.2.1 Appendix D - GeoSearches, Inc.
