perform additional assessments or modifications to the preliminary analysis as are required. 1.3.11 Develop preliminary cost estimates for the preferred alignment. 1.3.12 Prepare and deliver to the City a preliminary engineering report documenting the results of the preliminary analysis and including all items collected during preliminary design. 1.4 TASK 3 - BOUNDARY AND ROUTE SURVEY The Engineer will: 1.4.1 Establish primary horizontal and vertical control along the Project route. Engineer will base horizontal coordinates on the Texas Coordinate System, South Central Zone, NAD83, grid values tied to existing, published horizontal control monuments. Vertical datum will be NA VD88, based on survey ties to existing, published, vertical control monunlents. 1.4.2 Utilizing the established Project control, will provide 50 foot wide cross sections of the proposed route at approximate 50 foot intervals and all major grade breaks. Engineer will locate all improvements such as visible utilities, fences, roadways/driveways within the limits of the survey. The Engineer will tag and locate all trees eight inches in diameter (measured breast high) and greater. The Engineer will provide a tree list with tag numbers, tree diameter and species ( common name) in ASCII format file. Using the formula of one foot of crown radius for each inch of trunk diameter, the Engineer will show the calculated canopy for all located trees. 1.4.3 Utilizing AutoCAD and EaglePoint (or Microstation and GeoPak if required) digital terrain modeling programs, prepare a one-foot contour interval topographic map for the Project route. This topographic map will show the location of the visible improvements, visible utilities, trees and tree list with the contours. 1.4.4 Research the Hays County Real Property and Plat Records, the Central Appraisal District, and TxDOT records to identify the properties being crossed by the proposed water line. The Engineer will prepare a working sketch, which does not include research of recorded easements, based on the research data obtained. The Engineer will make survey ties in the field to survey monuments and other evidence of property comers. Engineer will analyze the survey data in the office and construct boundaries. The locations of the boundary lines being crossed will be determined. The Engineer will include the boundary information as part of the design survey data. 1.4.5 Prepare up to three field note descriptions with sketch/plat for acquisition of permanent and temporary construction easements. The location of proposed easements will be detemlined in coordination with the City. Engineer will base the field notes and sketch on boundary surveys performed by it along the Project route. The Engineer will mark the comers of the proposed easement parcels as needed. 4
