City of Sunny Isles Beach, Florida Shoreline Surveying and Mapping Consulting Services CB&I Environmental & Infrastructure, Inc. RFQ No. 16‐06‐01 20 10C062016D – 631216982 changes, shoreline position changes, berm height changes, and other project specific parameters that can be addressed to answer beach performance and stability concerns. CB&I uses several tools and methods to quantify beach changes including proprietary programs, AutoCAD Civil3D, ESRI ArcMap, ESRISpatial Analyst, Delft3D, and other methods. Every situation is unique and CB&I has the flexibility and expertise to handle any situation. 5.4 Maintaining Horizontal and Vertical Control CB&I has performed several geodetic and tidal control surveys throughout the southeastern United States. Survey control and geodesy is continually evolving and CB&I surveyors strive to maintain cutting edge survey practices and stay current on all geodetic advancements made by the National Geodetic Survey. CB&I surveyors use both Trimble Business Center and NGS OPUS‐Projects to process and document control surveys. Static GPS methods are employed when published high order monuments are not located within the project area or the stability of such monuments is questioned. NGS OPUS‐Projects is a powerful tool that allows for session based GPS static processing. As such, CB&I surveyors always deploy multiple GPS receivers that log satellite data simultaneously. This simultaneous collection allows for fully constrained horizontal and vertical adjustments to the control points relative to NGS Continually Operating Reference Stations (CORS). This results in highly accurate control relative to the current datum and geoid. Further, OPUS‐Projects can transform control points to alternative datum and geoids allowing for comparison to preceding data sets or control tabulations that may be relative to a previous datum. 5.5 Related Engineering Services, As Needed The behavior of beaches, inlets and coastlines can be complex and sometimes dramatic. To overcome these complexities and test a wide range of solutions, CB&I bases each project design on proven engineering principles with the added benefit of cutting‐edge numerical models. CB&I engineers are on the forefront of coastal modeling. We own and operate one of the most advanced coastal modeling suites available today: Delft3D. We use these models to increase ease of federal and state permitting of beach nourishment and coastal structures projects. Our team of experienced physical oceanographers and coastal engineers, who are strongly grounded in coastal process theory and applications, develop our modeling projects. In doing so, we review our model results in the context of overall project objectives, and incorporate them into designs and analysis as a tool to improve performance and longevity of the project and minimize environmental impacts.
