C -- ARCHITECT/ENGINEER SERVICES SOL DACW69-95-R-0041 POC Contact Point, Janice C. Swann, (304)529-5961, Contracting Officer, LENORA L. SUTPHIN, (304)529-5620 The work and services to be accomplished will consist of providing, on an individual work order basis, hydrologic and hydraulic studies necessary for flood emergency plans for Corps dams which include preparation of inundation maps for potential flooded areas under various emergency conditions; hydrologic and hydraulic studies to develop alternative plans for increasing spillway discharge capabilities, studies for flood insurance and Local Protection Projects; the formulation of lake sedimentation reports; the performance of water quality investigations; the collection of water quality field data and analytical laboratory services for chemical testing; the performance of navigation studies; the formulation of drought contingency plans, and formulation of Water Control Management Manuals. The preparation of inundation maps for potential flooded areas below District dams, under emergency conditions, would include the use of data from topographic maps, river channel and flood plain cross section and discharge data in appropriate computer models to prepare maps showing the limits of inundation below the dams spillway design flood conditiions, with and without failure of dams. Hydrologic and hydraulic studies will be used for development of alternative structural plans for modifying existing spillways to satisfy current design criteria with respect to discharge capability and freeboard. Such alternatives may include (a) widen the existing spillway, (b) provide a gated spillway at the existing site; (c) auxiliary spillways; (d) raise the dam; and (e) combination of the preceding. Flood insurance studies would include the use of topographic data, river channel and flood plain cross sections and discharges to produce 10, 50, 100, and 500 year flood profiles (using step backwater computer models), to develop flood boundary maps and floodways, to determine flood hazard factors and to determine flood hazard zones. Local protection studies would include the development of hydrologic and hydraulic data necessary to design interior drainage systems (behind floodways) and pumping station facilities and to develop river channel relocation and/or modification schemes to mitigate local flooding problems and to determine the upstream and downstream effects of such schemes. Lake sedimentation reports may include, but would not be limited to: determine lake storage volume in 1 foot vertical increments between sediment ranges positioned at various locations across the lake; determine original and resurveyed sediment range profiles from furnished field survey data; compute volume and distribution of sediment in lake using Corps of Engineers computer program; determine rate of sedimentation in lake; prepare report and exhibits comparable to previous District sediment reports describing land usage, precipitation, report sediment problems, volume, distribution, and rate of sedimentation, conclusions, recommendation and prepare form 1787 reservoir sediment data summary. Prepare sediment reconnaissance reports for various District lakes which may include but not be limited to: field reconnaissance of lake area and drainage basin; analysis of lake bottom profile from fathometer charts obtained at various locations across the lake; preparation of reports comparable to previous District sedimentation reconnaissance reports describing current and anticipated sedimentaiton surveys. Formulation of Water Control Management Manuals would include the writing of required manuals and drafting of exhibits in accordance with prescribed format. The work described herein may be any place within the geographical areas of the Huntington District which covers 45,000 square miles and includes portions of five states within the Ohio River Drainage Basin. In addition to most of West Virginia, the District includes about one half of the State of Ohio, and smaller portions of Kentucky, Virginia, and North Carolina. A fixed price indefinite delivery contract will be awarded which will consist of individually negotiated work orders not to exceed $150,000.00 each with a cumulative total not to exceed $750,00.00 during a one year period. The contract will contain an option to extend the terms of the contract for one additional year. Criteria which will be used in evaluating A-E firms to be considered is as follows: (1) Diversity of professional staff as it relates to the performance of the functions described herein; (2) Familiarity with and experience in utilization of the HEC-2 computer model and the National Weather Service Dambreak model; (3) A minimum of four Hydrologic/Hydraulic Engineers with a minimum of five years experience in hydrologic activities and hydraulic design; (4) Capability to perform the work in a timely manner; (5) Experience in technical report writing; (6) Past performance evaluations; (7) Current workload both in and out of DoD; (8) Geographic location in relation to the Huntington District office. Firms having capabilities to perform the work and who desires to be considered, must submit a completed SF 255 and all appropriate data. In order to be considered for selection, you must note in Block 10 of the SF 255 all DoD contracts awarded to your firm and all affiliates (do not include consultants) during the last twelve months along with the dollar amounts of the awards and the total amount awarded. Only SF 255's received in this office within thirty (30) days from the date of this notice will be considered. If an SF 254 is not on file with the U.S. Army Corps of Engineers, a current SF 254 should also be included. The revised edition of SF 254 and SF 255, dated 11/92 must be used. This is the ''ONLY'' edition that will be accepted. No other general notification to firms will be made and no further action is required. This is not a request for proposal. THE PROPOSED PROCUREMENT IS UNRESTRICTED. (0198)
