This is a service / maintenance or supply contract in Columbus, Ohio. Contact the soliciting agency for additional information.

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 work may include but is not limited to studies, investigations, inspections and evaluations of existing conditions, geotechnical and geophysical investigations, report preparation, preparation of engineering drawings and specifications, and preparing construction contract documents. The Offeror must have experienced personnel and equipment for performing this work. This is a unique project necessitated by concerns of the potential presence of subsurface void(s) under the City's Jackson Pike electric substation. The method of Contractor Selection has not been Determined at this time.
