WBK OAN engineering Exhibit A - Proposal for Bowman Creek Concept Engineering City of South Bend Indiana December 9, 2019 Alicia Czarnecki, CDT Project Engineer Department of Public Works (574) 235-5903 City of South Bend 227 W. Jefferson Blvd., Suite 1316 South Bend, IN 46601 Dear Ms. Czarnecki: WBK Engineering, LLC (WBK) is pleased to provide this proposal to the City of South Bend (Client) for professional engineering services for improvements to Bowman Creek. WBK looks forward to the opportunity to assist South Bend on the due diligence and conceptual design of improvements at the mouth of Bowman Creek in South Bend. Included below is our understanding of the assignment, scope of services, project assumptions, and estimate of fee. Understanding of the Assignment WBK understands that the mouth of Bowman Creek between Lincolnway East and the St. Joseph River (approximately 160 feet) has severe erosion along its banks with steep slopes, exposed manholes, debris, and portions of Lincolnway Bridge in the stream. The City would like to provide possible enhancements to the area including sidewalks and pedestrian access to the mouth of the Creek, lighting, landscape, and streambank stabilization. The City's ultimate goal would be to prepare plans, specifications and estimates for the proposed improvements to bid to a contractor. WBK recommends a conceptual design phase to look at different options for enhancement of the area, and prepare conceptual cost estimates and exhibits to allow the City to determine the preferred enhancements and further refine the scope of the project prior to starting final engineering and permitting. This proposal outlines the recommended tasks for the conceptual design phase. Scope of Services Task 11 Topographic Survey We will utilize a one man survey crew with GPS and Robotic survey equipment to collect all physical features including all marked utilities, trees over 6 inches in diameter, structures, pavements, and elevations between Lincolnway and the St. Josephs River necessary for preparation of an existing conditions drawing. All elevations will be on NAVD 88 datum with state planes for the horizontal datum. From the survey data, an existing conditions drawing will be produced with all boundary lines (GIS), one foot contours and spot elevations showing the drainage of the site. WBK's Environmental Resource Specialist will make a visit to the site to determine tree species so this information can be added to the existing conditions base drawing and used in concept design. The existing conditions drawing will be used during the conceptual engineering phase of the project and will also carry over to final engineering. We assume a boundary survey of the site will not be required and that GIS data will be provided by the client.
