Reporting will consist of the formulation of a report defining the field, laboratory and analyses results along with appropriate geotechnical design recommendations.

Modeling Services: Services may consist of the identification, compilation, review and evaluation of any existing pertinent data to determine its utility for the implementation of a hydrologic study of a project area. Examples of data that may be needed include existing or predicted water levels, stream flows, wave propagation, siphon discharge, salinity, rainfall, wind topography, bathymetry, etc. Collection of project specific field data and information if determined necessary for use in modeling/design of a project. The proposed method for performing a hydrologic study of the project area shall consist of the formulation of a report detailing the Hydrological Analysis/Model selection. The methodology for the hydrologic study shall be approved by NRCS, and contain, at a minimum, the formulas and rationale used for a mathematical simulation and/or a description of the software used for a model. Hydrologic Analysis/Model Setup will include the identification and providing rationale for all parameters, including assumptions used for geometric setup, boundary configuration and data input.

Hydrologic Analysis/Model Calibration will include calibration to reasonably assure that the assumptions, setup parameters, and methodology used for the analysis are capable of simulating observed responses. An acceptable level of accuracy, to be determined upon model selection, shall be attained before applying scenarios. Hydrologic Analysis/Model Scenarios may include the simulation of specific scenarios for the given project area. NRCS will provide input regarding project boundaries, scenarios and time frames for which the analyses will be performed. Hydrologic Analysis/Model Results may consist of the formulation of a report containing the following information 1) narrative of items noted above to include all calculations and documentation used to support the model conclusions 2) GIS map showing the project area, project features and any data locations used for the simulation 3) narrative and graphics of the results of the scenarios evaluated and 4) report shall be signed and sealed by a Licensed Professional Engineer.

Design Activities: Services may consist of, but are not limited to, any part, one or all of the following: 1) prepare construction and material specifications, 2) prepare construction plans (drawings), 3) prepare land rights work maps, 4) prepare cost estimates, 5) prepare bid schedules,

6) prepare construction performance time, 7) prepare quality assurance plans, 8) prepare operation and maintenance plans, 9) prepare design folders and reports, and 10) prepare and/or obtain all necessary permits (i.e. COE 404 permits, etc.) as may be required for the project.

Specifics for each project will be outlined in each individual task order. The typical project could require knowledge and experience in all aspects of engineering design associated with the design of the types of projects denoted above. The firm will be required to interpret hydrologic and hydraulic reports as well as geotechnical reports, and accurately apply the data to the design of the project measures. The firm will be required to perform engineering design activities in accordance with NRCS standards. The majority of the work will be civil and/or agricultural;

however, electrical and mechanical engineer expertise may be required on some projects.
