County GIS Vertical Control Mapping <br /> EXHIBIT A <br /> globalmind <br /> Indian River County Benchmark Database - Update <br /> Scope o1' Services <br /> GlobalMind will update approximately eleven hundred ( 1100) 2eodetic vertical control points (benchmarks) <br /> daoughout Indian River County previously im'entoried and compiled into a Geographic Information System <br /> which facilitates efficient staff and public access to the benchmark data Due to a recent adjustment performed <br /> by the National Geodetic Survey, the benchmark information now maintained does not conform to the new <br /> adjustment. GlobalMind win also add apptaaimmtely one hundred ( I06) new benchmarks established by Indian <br /> River County and povidle training to County staff. <br /> GlobalMind will complete the following work items: <br /> 1 . Update the Benchmark Datasfeets with the following information and creak entries for tte newly <br /> established benchmarks: <br /> • Benchmark Designation • Range <br /> • NAVD 88 Elevation (ft) • Quad Now <br /> • NGVD 2_9 Elevation aft) • Field Book & Page <br /> • Vertical Order • To Reach Description of available ) <br /> • Section • Horizontal Coordinates <br /> • Township <br /> 2. Update the ANGIS geodatabase with readjusted elevations forcreating benchmark datasheets. <br /> Add the newly established tenchnnrks to the geodatabase. <br /> 3. Create a book containing the revised Benchmark Datasteets. The hookwill contain an index by <br /> PLS S sectioNtownshiptrange and an index byroad name. Fifteen ( I5) of the books will be <br /> created for the County. The book will also contain nap steels showing the locations of the <br /> benchmarks, along with hine ork for roads, subdivisions and PLSS. A separate sleeve in the book <br /> will contain a pocket for a CD with the datasleets, database, interactive ArcReader map, <br /> installation files and PDF naps. Tie ArcReader map will have accompanying encrypted file <br /> geodatabase for distribution. <br /> 4. Prepare training materials and provide a half-day training session N Indian River County staff on <br /> crap maintenance. updating and other important topics related m their inernal use and upkeep of <br /> the project &liverables. <br /> The county will provide the following itenLc to GlobaDdind: <br /> I . Excel spreadsheets containing data for point names, NAVD BBekvations. NGVD 29 elevations, <br /> descriptions and Feld book and page numbers for the Indian River County Vertical Control <br /> Benchmarks — including new benchmarks not included in Work Order 3. <br /> _. AutoCAD drawing in DWG format that contains all of the benchmarks to be compiled in this <br /> project. The benchmarks will be in point format with the benchmark designation being a point <br /> attribute. <br /> The fee for these services shall be Fight Thousand Five Hundred ($8.500) dollars. <br /> GlobalMind will deliver one sat of deliverables 3 weeks after receipt of the notice of commencement. <br /> Indian River County will have 30 days to respond with comments to the initial submit. Upon receipt of the <br /> comments. GlobalMind will prepare the final project deliverables within 2 weeks. <br /> 1933 commonwealth lane tallahassee, fiondi 32303-6143 ph'. 850-222-0539 :'ax: 8,50-222 -4255 <br /> iv. vw. lglobah€rind.rnun emai : iafoExiglobalnair.d om toll free: 008-316-1005 <br /> PALPI BEACH GARDENS TALLAHASSEE <br /> Page 5 of 6 <br /> Work Order No. 5 Additional Services <br /> >F:\Engineering\Capital Projects\0504 Township- Mapping Projec[Wick Miller contract\Work Orders\WO 5 Add-Sry Vert mapping 5- 13- <br /> 08\0504 WO 5 Add Services Vertical Mapping 5-13-08 mob.doc <br />
