RECOVERY--C--TASK ORDER 0010 CREST GAGE SURVEY

The Portland District Corps of Engineers is set to issue Task Order No. 0010 under a previously awarded Architect-Engineer Indefinite Delivery Indefinite Quantity (AE IDIQ) contract to HDR, using recovery act funding. The task requires the contractor to provide all necessary equipment, supplies, facilities, and personnel to perform survey and maintenance services on 134 crest gages located across ten counties in Oregon. There is also an option to extend the work to include up to 65 additional gages in 12 more counties spanning Oregon and Washington. Key activities include locating each crest gage and any associated reference monuments, clearly marking them, determining and establishing elevations both for the crest gage datum and the monuments, recording readings, and preparing detailed narrative descriptions. All data and deliverables must conform to standardized geospatial references, specifically using the Geographic Coordinate System with the North American Datum of 1983 (NAD83) for horizontal positioning, and the North American Vertical Datum of 1988 (NAVD88) for vertical elevation measurements. This Task Order falls under NAICS code 541330 and is managed by the Portland office of the Department of Defense. The scope emphasizes precision in geodetic surveying to ensure proper maintenance and monitoring of these critical hydrological instrumentation sites across the targeted regions.
