C -- ARCHITECT-ENGINEER SERVICES FOR HYDROLOGY, WATER QUALITY, AND HYDRAULIC DESIGN SERVICES WITHIN THE MISSION OF THE WALLA WALLA DISTRICT SOL DACW68-99-R-0007 DUE 061199 POC Charlene Duncan at 509 527-7207 or charlene.c.duncan@usace.army.mil E-MAIL: ARCHITECT-ENGINEER SERVICES FOR HYDROLOGY, WATER QUALITY,, charlene.c.duncan@usace.army.mil. The above subject was posted in CBDNet on April 19, 1999 and printed in the issue date of April 22, 1999. THE DUE DATE FOR SF 254/255'S HAS BEEN EXTENDED TO CLOSE OF BUSINESS ON JUNE 11, 1999. The following sections have been modified: 2. PROJECT INFORMATION: Experience is required in the three following areas: hydrology, water quality, and hydraulic design. The potential contractor shall have a high level of demonstrated experience and expertise in Pacific Northwest Watershed systems to equally serve the following three work categories. (1) Hydrology: perform detailed hydrologic analysis, open channel hydraulic analysis, sediment transport analysis, floodplain analysis, reservoir regulation analysis, ice engineering analysis, dam break analysis, flood damage analysis, flood damage economic analysis, and other related analysis using computer models such as HEC-1, HEC-2, HEC-RAS, HEC-5, HEC-5Q, HEC-UNET, HEC-6, HEC-FFA, HEC-IFH, HEC-DSS, HEC-FDA, HEC-PRM, STATS, HMR52, HEC-HMS, TABS, and other related models; collect data using acoustic doppler equipment, streamgages, air photography, land and hydrographic surveying; perform other related data acquisition activities; and provide programming/database and GIS/CADD support services. (2) WATER QUALITY: Conduct sampling, analysis, and data synthesis for water and sediment and soil quality and perform related limnological and biological and chemical analysis studies; use equipment such as multi-parameter data sondes, chemical auto analyzers, dopplers, echosounders, automated samplers, core samplers, Niskin bottles, plankton tows, submarine spectrophotometers; install and maintain remote sensing equipment; perform technical writing services; perform complex statistical analysis; provide geo-spatial/GIS/CADD system support and evaluate new technologies and instrumentation; and provide sample analysis plans, permit services, and any other quality related studies. (3) HYDRAULIC DESIGN: Provide analysis, reports, and designs related to hydraulic features of large multi-purpose hydroelectric projects, open channel flow systems, pressurized water-hydraulic systems, fish passage facilities, hatcheries, fish holding facilities; develop, construct, calibrate, and test physical scale hydraulic models; conduct full scale prototype tests; develop and execute 3D Computational Fluid Dynamic Models; analyze and design wastewater or water supply systems, small flood control structures, diversion structures, intakes, irrigation structures, levee systems; perform all aspects of navigation studies; provide mapping services, physical data collection, drafting services (manual and CADD), specialized engineering technical services (Electrical, Mechanical, Structural, and Civil Engineering); perform cost-benefit analysis, economic studies, engineering feasibility studies; and perform any study necessary for hydrology and hydraulic design even if not previously mentioned in other categories. 3. SELECTION CRITERIA: Criteria A through C are primary and are listed in order of importance. The remaining categories are for tie-breaker purposes. A. Professional qualifications, necessary for accomplishment of the listed tasks in section 2. B. Specialized experience and technical competence in the type of work discussed in section 2 above. C. Capacity to accomplish the work in the required time frame. D. Past performance on contracts with government agencies and private industry in terms of cost control, quality of work, and compliance with performance schedules. E. Location in general geographical area of the Walla Walla District with the capability of quick turn around to and from Walla Walla, Washington. However, work could occur anywhere within the geographic area of the Corps of Engineers Northwestern Division. F. Extent of participation of SB, SDB, WOSB, historically black colleges and universities, and minority institutions in the proposed contract team, measured as a percentage of the total estimated effort. G. Volume of DOD contract awards in the past 12 months as described in Note 24. Posted 05/08/99 (W-SN329289). (0128)
