RBF is proficient with Bentley MicroStation and has utilized this software on freeway, interchange and other civil <br />engineering design projects. We are currently using Bentley MicroStation V8i Select Series 2. And we also utilize <br />Bentley MicroStation version V8 2004 edition for legacy or ongoing projects. RBF has utilized Bentley MicroStation <br />while working with the following clients including: Port of Long Beach, Caltrans, Orange County Flood Control <br />District, U.S. Army Corps of Engineers, Arizona Department of Transportation, City of San Diego, Riverside County <br />Flood Control,Los Angeles County and Metrpolitan Water District. <br />RBF has many of Bentley hydrology, hydraulics, and CADD programs such as <br />Storm and Sanitary network tools, Pond Pack, Flowmaster, Storm CAD, and <br />CivilStorm. The CivilStorm hydrodyanmic model uses two types of finite <br />difference engines to solve St. Venant's equations: the EPA SWMM <br />engineering and an implicit engine. RBF has extensive experience running the <br />EPA SWMM model and using it in master plans. <br />Hydraulic Analysis / Design <br />RBF Team members have technical competence and specialized experience in <br />steady and un-steady single- and multi-dimensional numerical models for the <br />hydraulic analysis and storm drain facility design. These models can analyze <br />surface water hydrology and hydraulics in various urban environments <br />including coupled 1-dimensional and 2-dimensional computer models that <br />incorporate surface and sub-surface conditions. The team has an in-depth <br />understanding of the EPA's SWMM programs, and the experience and <br />knowledge to identify appropriate applications for the use of the software. <br />RBF prepared 1- and 2-D surface <br />and subsurface model using the <br />SWMM program for the <br />Midway City project. <br />The RBF Team includes recognized experts in the application of hydrodynamic modeling. RBF's Mr. Tom Ryan <br />recently presented an internationally attended webinar for XP Solutions on "Urban Flood Modeling using 1D, 2D, <br />and Coupled 1D/2D models in Southern California." The webinar was viewed by over 280 participants from five <br />different countries. <br />For the Midway City Street and Storm Drain project, RBF developed a coupled 1- and 2-dimensional model of the <br />existing and project conditions using the SWMM program to assess the benefits and impacts associated with the <br />phased installation of the new storm drain system in the existing community. This analysis provided the necessary <br />documentation to show that the phased installation of the proposed improvements would not transfer the <br />flooding problems to the adjacent areas, and allowed the County to move forward with the phased construction of <br />the project without expensive and complicated mitigation measures. RBF identified the existing and project <br />condition surface flooding and used GIS tools to assess the impacts and develop <br />- graphics to clearly document the change in surface flooding depths as a result of <br />the project improvements. <br />5 <br />Tustin, Hydrodynamic Surface <br />Flow Model Results for <br />maximum flooding depths <br />Pl? <br />RBF recently completed a study for the City of Tustin to assess drainage <br />improvements necessary for the reuse of the former Tustin Air Base. The <br />original master plan included offsite improvements in the adjacent city to <br />provide the required flood protection. Right-of-way and other constraints <br />associated with the offsite improvements would have resulted in significant <br />schedule delays and cost millions of dollars to construction. RBF proposed a <br />coupled 1- and 2-dimensional hydrodynamic model for the base re-use without <br />the offsite improvements to evaluate flooding limits and maximum ponding <br />depths. The SWMM program was used for the analysis. The model evaluated <br />the proposed on-site storm drain system and site grading. We used the results <br />20C-16 <br />Bentley /MicroStation Experience
