Description
CURE BREAKWATER National Park Service Denver Major Acquisitions Buying Office (MABO) Lakewood, Colorado 80228 11/14/2012 This is Amendment # 2 to Solicitation Q1379130007. The purpose of this Amendment is to note a second set of questions, and responses for questions that arose either at the site visit or as may have been presented up to the date of this Amendment posting. Please see amendment # 1, for the initial set of questions and responses that included questions that were presented at the site visit. All offers are due 11/21/2012, therefore any questions presented after this amendment # 2, will likely not have adequate time for response for offer consideration. QUESTIONS WITH RESPONSES. 1) Stevens Creek Wave Attenuator must be attached to shore. Why is this requirement and the purpose served. Response: The Wave Attenuator needs to be attached to shore to allow the flexibility in the breakwater as the reservoir level rises and falls. 2) IOLA Wave attenuator seems to require two anchoring systems, one for high water and one for low water. Does this suggest that the wave attenuator is actually disengaged from the high water mooring system, moved to the low water mooring system, and then attached to the low water system, and vice versa, and how far is the move? Response: Due to topography of the IOLA location and the effects of the wind and ice, the NPS anticipates the need for two mooring locations. The move is approximately 200 to 300 feet. 3) Will the inshore ends of both wave attenuators set on the lake bottom, above the water line, at times of water level variation? Response: Likely, dependent upon water leveyel. If so, how much of each Wave Attenuator sits on the lake bottom at times of Extreme high water (presumably zero percent), how much sits on the lake bottom at times of minus 35 feet, and at what water level does each in shore end first come to rest on the lake bottom for each Wave Attenuator? Response: At high water, zero. At low water, it is unknown. The offeror is responsible to investigate the existing conditions and determine for themselves, how much of the Wave Attenuator will rest on the ground at low water. This would vary amongst varying types of attenuators. The wave attenuator is expected to be able to be moved closer away/from the shore as the water level rises and falls. However, there will be some of the wave attenuator rest on the ground when the reservoir level is at some point below full pool. That level is unknown and will likely vary. 4) Please describe the scope of the wave attenuators being moved around as this would impact the mooring system. Response: The NPS staff moves the wave attenuators towards/away from shore as the lake level rises and falls. In the winter, the attenuators may be moved closer to shore to minimize the action of ice, wind , and flowing ice and allowed to freeze in the lake. The attenuators need to be capable of resting on exposed lake bottom at lower water levels without damage to the attenuator. 5) Is there additional information about the sand/gravel lake bottom such as depth of sand and gravel over the solid bedrock? Response: We do not have additional information for this specific information at this time. A site visit was conducted in which it was recommended for interested parties to examine the site conditions. At this time the reservoir is at its lowest level in past twelve years, resulting in a higher amount of exposed shore line. 6) If the wave attenuator hits the ground and cannot be moved because of low water will this fail your specific requirements? Response: per specifications; The contractor shall supply a wave attenuator capable of being grounded and moved along the ground without damage to the attenuator. The attenuator shall be capable of withstanding axial movement as a result of the attenuator being grounded at lower water levels. The attenuator must have the capability of being able to be moved around, as needed to maximize protection to the boat launch ramps. (reference SOW section 15) It is the purpose of the Source Selection Evaluation Board to evaluate all submitted offers to determine which offer will be considered the best value to the government. All offers will be evaluated per the source selection criteria that are provided in the solicitation and the requirements specified in the Statement of Work. All offers will be evaluated in strict conformance to those criteria. 7) Is the lake bottom flat and level? Response: No, both areas vary, reservoir bottoms are unknown. However, at low water the areas appear to have a combination of rock, mud and varying angles of slope. 8) Do you plan on taking out and moving onshore the wave Attenuator anytime? Response: not planning on moving it other than keeping up with the water level as the reservoir empties and fills. Have you in the past to work on? Response: No, Maintenance on system should be minor other than winch system maintenance, which would not require removal. 9) Would an ALL Concrete Structure meet all your requirements? Response: It is the purpose of the Source Selection Evaluation Board to evaluate all submitted offers to determine which offer will be considered the best value to the government. All offers will be evaluated per the source selection criteria that are provided in the solicitation and the requirements specified in the Statement of Work. All offers will be evaluated in strict conformance to those criteria. Reference the criteria stated in the solicitation document and the SOW.
