This notice is provided for information purposes only. This opportunity is only available to the contractor under Contract AG-3A75-C-09-0019



A task order will be issued to HDR Engineering for independent design review of an ARRA Rehabilitation project in the state of Georgia located at Marbury Site 22.



The Contractor shall furnish the personnel, equipment, labor, materials, transportation, and facilities required to perform the services described herein:



I. Purpose



The Contractor shall perform an independent review as required by the policy of the USDANatural Resources Conservation Service as stated in the National Engineering Manual (NEM) Part 501.05(a), Part 520.26 and Part 511.05(b). The NEM defines independent review as an examination and evaluation of procedures used and decisions made during the design of a dam by peers from outside NRCS or from an organizational unit other than the one responsible for the design. The NEM requires an independent review of designs for engineering job class VII and other projects, as determined, based on their complexity and potential hazard The Contractors capability must be equal to that needed to independently perform the design.



Independent reviews are made to verify that design and construction procedures and decisions reflect safety considerations as well as economy. Dam safety considerations are directly related to the potential for loss of life, damage to valuable property, or disruption of transportation and utility facilities if the dam fails. The classification of dams is determined by the potential for such losses and damage (see NEM 520.2l). The Contractor shall determine whether the methods of analyses are appropriate and the assumptions are justified by the site conditions, as well as whether the results are reasonable. The Contractor shall verify that the design:



Addresses all potential dam safety deficiencies

Safely and effectively meets the stated objectives

Addresses unique site conditions

Is consistent with industry practice for similar structures

Generally complies with, or has appropriate variances to, the more stringent of NRCS or applicable state policy and criteria. (Note: A waiver of NRCS hydrologic design criteria has been granted to allow modification of this dam to Georgia Department of Natural Resources, Environmental Protection Division, Safe Dams Program hydrologic criteria.)
