Scope of Project:
A. Project Description
Professional engineering services are being requested to initially provide an engineering review, assessment, and recommendations for water movement, transfer and seepage in the Lake White reservoir and groundwater system at Lake White State Park, owned by the Ohio Department of Natural Resources (ODNR) and located in Pike County. The selected firm may also provide preliminary design, final design and construction administration as improvements and interim measures are identified and funded.
Lake White Dam is a Class I high-hazard potential structure. Lake White Dam consists of an earthen embankment with concrete spillway and is 39 feet tall and 4200 feet in length and impounds 6015 acre-feet of water at normal summer pool. The principal spillway is a 128-foot-long concrete weir with two adjustable gates. SR 104 stretches along the crest of the dam, with a bridge above the concrete spillway. Construction of Lake White Dam was completed in 1935. Phase I dam improvements were completed in 2006. In 2015, construction of Phase II dam improvements commenced. Phase II improvements included installation of a new lake drain system, roller compacted concrete overtopping protection system, a new bridge deck over the spillway, and a chemical grout curtain in front of the existing spillway system. Approximately one month after substantial completion of the dam improvements, seepage issues were observed downstream of the dam and significant water loss was detected through reservoir elevation monitoring. ODNR is in the process of addressing seepage issues by installing filter berm improvements on the downstream toe of the dam but significant water loss persists.
Through this selection process, ODNR contemplates engaging an Architect/Engineer (A/E) to provide engineering review, assessment, recommendations, preliminary design and construction documents. The initial Phase I would include engineering review, assessment, and recommendations as a study and report. This study and report will utilize the latest technology and analysis to identify and resolve water losses from within the Lake White reservoir system. ODNR encourages proposing firms to identify partnering opportunities and team oriented strategies to provide the department with the most effective and efficient means and resources to restore normal operating pool elevations within the reservoir system. ODNR expects an initial report from the selected firm within four to six months of an executed agreement. Future phases, if implemented, would include completion of selected recommendations.
All firms submitting a statement of qualifications will be eligible for award of contract for Phase I work which may be extended and amended to add additional phases of work as capital appropriations are available in future Capital Bill legislation.
Interested firms are encouraged to review the information available via the ODNR website at http://engineering.ohiodnr.gov/dam-risk-reduction-program/current-projects/lake-white-dam

B. Scope of Services
The scope of services may include, but is not limited to; topographical and bathymetric surveys of the dam site, including upstream and downstream areas; performance of geotechnical investigations of the dam and appurtenances to evaluate stability, seepage, and structural condition; underwater inspection; performance of hydrologic, hydraulic and hydrogeologic analyses to determine water balance and reservoir operations; recommendations of alternatives for rehabilitation of reservoir systems with associated cost estimates; applying for and obtaining all applicable permits and approvals; completion of preliminary and final design documents for construction; and performance of construction administration services. All work shall be performed in compliance with Ohio Dam Safety Rules and Regulations.
The selected Architect/Engineer (A/E), as a portion of its required Scope of Services and prior to submitting its proposals, will discuss and clarify with the Owner and/or the Contracting Authority, the cost breakdown of the Architect/Engineer Agreement detailed cost components to address the Owner’s project requirements. The selected Architect/Engineer (A/E) will participate in the Encouraging Growth, Diversity & Equity (EDGE) Program as required by statute and the Agreement.
If implemented, during the construction period, provide not less than 16 hours (excluding travel time) on-site construction administration services each week, including (1) attendance at progress meetings, (2) a written field report of each site visit, (3) on-site representation comprised of the A/E and its consultant staff involved in the primary design of the project, all having relevant and appropriate types of construction administration experience.
As required by the Agreement, and as properly authorized, provide the following categories of services: Study and Report, Preliminary Design, 50% Design Stage, 90% Design Stage, and 100% Design Stage, Construction Administration, Post-Construction, and Additional Services of all types.
Refer to the Ohio Facilities Construction Manual for additional information about the type and extent of services required for each. A copy of the standard Agreement can be obtained at the OFCC website at http://ofcc.ohio.gov.
For purposes of completing the Relevant Project Experience Matrix in Section F of the Statement of Qualifications (Form F110-330), below is a list of relevant scope of work requirements for this RFQ:
1. Experience with locating and identifying indeterminate water movement and seepage within earthen dams, reservoirs and groundwater systems.
2. Performance of hydrologic, hydraulic and hydrogeologic analyses for reservoirs and groundwater systems.
