Mr. Steve Gallup <br /> "February 1, 2006 <br /> Page 2 <br /> SCOPE OF WORK <br /> At this time we have identified the following tasks as the scope of work for this project: <br /> TASK 1-CONTRACT MANAGEMENT AND COORDINATION <br /> The goal of this task is to establish the lines of communication and to set forth the priorities <br /> between City and OBEC. As the work progresses, the objectives will include keeping the Oty <br /> informed of the work progress and aware of changes affecting the scope of work and related <br /> costs. <br /> TASK 2 -SURVEYING <br /> This task includes all surveying required to prepare mapping, design all elements of the project, <br /> and prepare right-of-way descriptions. Contractor shall include the following in performing this <br /> task: <br /> • Research and compile available survey data <br /> • Establish horizontal and vertical control points <br /> • Perform topographic surveying and mapping <br /> • Locate existing natural and man-made features <br /> • Tie horizontal locations of all utilities; in instances where there may be a major conflict with <br /> <br /> 'rlrr° utilities, tie the vertical location as well. <br /> • Prepare digital terrain model <br /> • Survey stream cross sections required for hydraulic~analysis <br /> • Tie wetland delineation and incorporate into the base map <br /> • Provide Base Map to tray tied to City benchmarks. This Base Map does not need to meet <br /> standard Gty format. OBEC standards are acceptable. <br /> TASK 3 ~ PRELIMINARY DESIGN OF BRIDGE AND HYDRAULIC ANALYSIS <br /> Hydraulic & Stormwater Design: This task includes analyzing the hydraulic conditions of the A-2 <br /> Channel at this location using the 100-year future flow predicted by the 1990 OTAK study. We <br /> anticlpate confirming that the 100-year water surface stays within the banks of the channel <br /> through the site. The bridge soffit will be placed at the highest elevation of the following: <br /> • One (1) foot above the 100 year elevation <br /> • Top of the benched banks <br /> . Sufficient height above the bottom of the channel as required by the Junction City Water <br /> Control District. Initial contact with the District (Larry Mikkeisen) indicates that they do not <br /> have any additional requirements for our bridge location. <br /> OBEC will prepare a "No Rise" Certificate as appropriate and determine scour requirements. <br /> OBEC understands that the City will provide OBEC with necessary stormwater requirements and <br /> that some measures and details may be required to be included in the project plans due to the <br /> additional impervious area of the bridge. <br /> <br />
