C -- ARCHITECT-ENGINEER SERVICES FOR HYDRAULIC/HYDROLOGIC STUDIES POC Donna L. Erwin, CONTRACT SPECIALIST (304) 529-5658 CONTRACT INFORMATION: Architect-Engineer Services will be required on an individual work order basis against an Indefinite Delivery Contract utilizing Architect- Engineer Services for various types of Hydraulic/Hydrologic Studies at various Civil Works Projects located within the Huntington District geographical area. The resulting Inde- finite Delivery Contract will be for a period of one year, with one option year. A fixed price Indefinite Delivery Contract will be awarded which will consist of individually negotiated work orders which cannot exceed $500,000.00 each since this is the cumulative total of the base contract period, with an additional one year Option period for the same amount. This announcement is open to all businesses, regardless of size. If a large business is selected for this contract, it must comply with FAR 52.219-9 regarding the requirement for a subcontracting plan on that part of the work it intends to subcontract. The plan is NOT required with this submittal.A Quality Control Plan will also be required at the time of the contract award. The wages and benefits of all service employees performing under this resulting contract must be at least equal to those determined by the U.S. Department of Labor under the Service Contract Act. (See FAR 22.10). 2. PROJECT INFORMATION. The work under this contract will consist of hydraulic/hydrologic studies necessary for Corps projects which would include preparation of inundation maps for potential flooded areas; development of flood evacuation and flood warning plans; hydrologic and hydraulic studies to develop alternative plans for increasing spillway discharge capabilities at Corps dams, studies for flood insurance and Local Protection Projects; the formulation of lake sedimentation reports; 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 at District Projects would include the use of data from topographic maps, river channel and flood plain cross sections and discharge data in appropriate computer models to prepare maps showing the limits of inundation in digital format at and below District projects. 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 capacity 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 using digital mapping. Local protection studies would include the development of hydrologic and hydraulic data necessary to design interior drainage systems (be- hind floodwalls) and pumping station facilities and to develop river channel relocation and/or modification schemes to mitigate local flooding problems and to deter- mine the upstream and downstream effects of such schemes. Lake sedimentation reports may include, but would not be limited to determine lake bottom profile from fathometer charts or GPS data; determine lake storage volume in 1 foot vertical increments; 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 text and exhibits comparable to previous District Sediment reports describ- ing land usage, precipitation, report sediment problems, volume, distribution and rate of sedimentation, conclu- sions, recommendations and prepare form 1787 reservoir sediment data summary. 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 Dis- trict includes about one half of the state of Ohio and smaller portions of Kentucky, Virginia and North Carolina. The Huntington District is now a part of the Great Lakes and Ohio River Division. (CELHD) 3. SELECTION CRITERIA: Criteria which will be used in the evaluation of the A/E firms to be considered are as follows and are listed in descending order of importance: (1) Diversity of professional staff as it relates to the performance of the functions described herein; (2)Familiarity with and experience in utilization of HEC hydrologic and hydraulic computer models, the National Weather Service Dambreak model and GIS computer models using ARCINFO; (3) A minimum of four Hydrologic/Hydraulic Engineers with a minimum of five years experience in hydrologic activities and hydraulic design and demons- trated expertise in current GIS hydrologic and hydraulic applications; (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; (9) Extent of participation of small businesses (including women-owned), small disadvantaged businesses, historically black colleges and universities, and minority institutions in the proposed contract team, measured as a percentage of the total estimated effort. 4. SUBMISSION REQUIREMENTS: Firms having capabilities to perform the work and who desire to be considered must submit a completed SF 255 and 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 amount of the awards and the total amount awarded. Only SF 255's receiv- ed in this office within thirty (30) days from the date of this notice will be considered. If the 30th day is a Saturday, Sunday, or Federal holiday, the deadline is the close of business of the next business day. Please note that Solicitation packages are NOT provided. If a SF 254 is not on file with the U.S. Army Corps of Engineers, a current SF 254 should also be included. See Note 24 for general submission requirements. All interested firms having the capabilities to perform this work must submit three copies of SF 255 (11/92 edition) and three copies of SF 254 (11/92 edition) for the prime firm and all consultants to the above address. No other general notification to firms will be made and no further action is required. This is not a request for proposal. (0293)
