E-MAIL: Cathy Vanatta, Cathy.L.Vanatta@usace.army.mil. AMENDMENT TO INDEFINITE DELIVERY CONTRACT FOR HYDROGRAPHIC SURVEYS AND RELATED DIGITAL PRODUCTS FOR THE OMAHA DISTRICT SOL DACA45-98-R-0021, posted May 14, 1998, published in CBD Issue No. PSA 2097, May 18, 1998. The Omaha District is seeking firms enrolled in the Small Business Administrations Section 8(a) program to provide surveying services. The original announcement referenced above was published in order to conduct a market survey to locate 8(a) firms that could lead a team capable of providing the services, and requested submission of a statement of qualifications (Standard Forms 254 and 255) from 8(a) firms. This amendment adds services to the original announcement. Firms intending to submit should include their qualifications for these additional services in their submissions. The services are indicated by making the following changes to the original announcement. Change the title to: SOURCES SOUGHT FOR HYDROGRAPHIC AND LAND SURVEYING AND RELATED DIGITAL PRODUCTS FOR THE OMAHA DISTRICT. In thesection titled CONTRACT INFORMATION, change the last sentence to read "Types of services required will include hydrographic, topographic, deformation and boundary surveying; GIS applications; mapping and related digital products." (c) Delete the section titled PROJECT INFORMATION and substitute the following: Task orders under this contract may include but not be limited to hydrographic, topographic, structural deformation, and boundary surveying, GIS application development, and related digital products to include digital orthophotography. All hydrographic work will be in the Missouri River system above Rulo, NE. Topographic and boundary work may be anywhere in the U.S. (with higher headquarters approval), but will be primarily within the Omaha District. Hydrographic work will require computer driven depth and position system with on-board plotting capability and boats ranging from 30 feet long to an airboat to a small outboard. The ability to provide positioning of the boat utilizing differential GPS techniques as well as traditional range/range and range/azimuth will be required. Topographic mapping will be required to be done with total stations, use of Global Positioning System (GPS), and photogrammetry. Utilization of break-line and mass point data collection technology will be required in all topographic mapping. Structural deformation surveying will be required to be performed on earthen dams as well as hardened structures throughout the civil boundaries of the District. First order horizontal and vertical surveys will be required for the deformation surveying utilizing first order electronic leveling instruments and survey grade GPS receivers. Static, rapid static, and RTK GPS survey techniques as well as conventional trilateration will be required in performing the horizontal positioning of the structural monitoring points. Boundary surveys must meet state codes and be signed and recorded by a surveyor licensed in that state. GIS products developed in the following GIS software will be required: ArcInfo, ArcView, MGE, Geomedia, Geowebmap. Database software used in conjunction with this software will include but not limited to Oracle, FoxPro, and Access. Databases will be required to be developed in an ODBC environment in various delivery orders. Electronic map files will be required. Digital map deliverables will be edited and developed using Bentley Microstation CADD and Inroads using Unix and Windows NT operating systems. Mapping and GIS products developed according to Tri-Services Spatial Data Standards will be required. Use of the metric system of measurement may be required for some deliverables under the proposed contract; however, metric system experience by submitting firms is not required for selection. (d) In the section titled SELECTION CRITERIA delete criteria (a)(1), (2) and (3) and replace with the following "Hydrographic, topographic, deformation, and boundary surveying, GIS application development and mapping as described above." In criterion (b) add the following disciplines: land surveyorand civil engineer. (e) In the section titled SUBMITTAL REQUIREMENTS, change the submission closing date to July 13, 1998. All other information in the original announcement remains unchanged. (0161)
