IDC for Foundation Pressure Relief Well Engineering with Geophysical Surveying for the Great Lakes and Ohio River Division

The A-E services to be performed under this contract includes but is not limited to design, studies, geophysical surveys, sampling, testing, permit procurement, and other similar activities related to Relief Wells, Extraction Wells, and/or Monitoring Wells. Tasks would include but not be limited to: Establishment, rehabilitation, maintenance, and abandonment of Relief Wells, Extraction Wells, and/or Monitoring Wells; Characterization of relief well conditions through various methods including Step-Drawdown, Constant-Rate, Specific Capacity Testing, and Recovery Testing (Residual Drawdown Testing). Assess Relief Well and aquifer conditions by hydraulic testing methods. Downhole Imaging to determine comprehensive condition of relief well (structural integrity, biological plugging, geochemical clogging, etc.). Analysis of contaminants and water chemistry: Geochemical sampling and analysis to determine baseline chemical characteristics of the well and aquifer. Analysis of microbes using the Biological Activity Reaction Test analysis, and other tests to allow for complete characterization of levels of biological activity. Complex modeling of system(s), both numerical and finite-element modeling. Traditional modeling of systems using methods such as Theis, Rorabaugh, Jacob, and Hantush-Bierschenk. Contractor shall perform redevelopment and/or rehabilitation to re- establish the operating condition of the relief well by mechanical and or the Blended Chemical Heat Treatment method and as required other methods to rehabilitate. Maintain collection, disposal, and treatment of wastewater capabilities. Perform accurate assessments of post-treatment effectiveness from baseline conditions. Installation of new wells. Perform preventative well maintenance including condition assessments, monitoring of geochemical and biological condition, and period treatments. Abandonment of existing wells in accordance with all relevant guidance. Perform comprehensive site assessments in order to complete design of new pressure relief well systems for various dam and levee projects. Review existing systems for performance, and recommend changes to systems to enhance or augment operation. Develop individual wells, well systems by performing various well development techniques. Develop and/or manage Individual and District wide relief well operation and maintenance plans. Analyze wells for efficiency and aquifer parameters. Perform computer modeling for design and data analysis. Conduct as necessary video inspections, visual inspections, geochemical analysis and biofouling analysis for toe drain piping, seepage collection piping, and other related drainage structures to perform maintenance and rehabilitation. Develop and manage individual and district wide maintenance programs, including maintenance monitoring, for pressure relief piping, relief well collector piping, and other related drainage structures.
