A -- BROAD AGENCY ANNOUNCEMENT CONCRETE HYBRID PIER STRUCTURES SOL N47408-98-R-3919 DUE 031798 POC Contract Spec. Naomi Melendez, 805-982-5095; Engineer Jon Reed, 805-982-6215 This announcement constitutes the Broad Agency Announcement (BAA) for the Naval Facilities Engineering Service Center (NFESC) under FAR 6.102 (d)(2) to solicit proposals for basic and applied research for new and innovative technology solutions to problems in the areas of FRP/CONCRETE HYBRID STRUCTURAL COMPONENTS FOR WATERFRONT CONSTRUCTION. Part of the proposed areas listed in these BAAs are being considered 100% Set-aside for Historically Black Colleges and Universities (HBCUs) or Minority Institutions (MIs) as defined by the clause at 252.226-7000 of the Defense Federal Acquisition Regulation Supplement. Interested HBCUs and MIs should provide the contracting office as early as possible, but not later than 15 days after this notice, evidence of their capability to perform the contract, and a positive statement of their eligibility as an HBUC or MI. If adequate response is not received from HBCUs and MIs the solicitation will instead be issued, without further notice, as unrestricted, to academic institutions, non-profit organizations, and private industry. The effective period of these BAAs is one year from the closing date. Awards may be made at any time throughout year. Award decisions on proposals will be based on a competitive selection of proposals from peer/scientific review. Evaluations will be conducted using the following evaluation criteria: 1. Overall scientific and technical merit, 2. Potential contributions of the proposed effort to the Navy's overall war fighting capabilities and related mission, 3. Past performance, 4. Realism of costs and availability of funds, and 5. Understanding of the research effort proposed, and experience and qualifications of key personnel/or institution or corporation submitting the proposal. Multiple Phase I contracts with a funding range of $25,000 -- $150,000 may be awarded; phase II and III may be awarded if sufficient progress is attained in Phase I. Developmental approaches should be suitable for demonstration in the follow-on phased effort estimated not to exceed 36 months. Interested parties should submit their proposal to the Commanding Officer, Naval Facilities Engineering Command Contracts Office, Code 2716-4, Bldg. 41, Naval Construction Battalion Center, 1000 23rd Avenue, Port Hueneme, CA 93043-4301, Attn: Ms. Naomi Melendez; (805)982-5095. No further paperwork will be provided for submission of proposals. A preferred method for submission of responses is: Microsoft Word format with Executive Overview in Microsoft PowerPoint. Contact with the NFESC engineer associated with this announcement is encouraged. All proposals should be submitted in original and 3 copies to the address noted above. In addition, all submissions should reference this announcement and should specifically identify the research area the proposal is responding to. Proposals will not be evaluated against each other since each is a unique technology with no common work statement. Proposals identified for funding may result in a contract, however, there is no commitment by the Navy to make any awards, to make a specific number of awards, or to be responsible for any monies expended by an offeror before award of a contract. The following is a description of the research required for this BAA. TOPIC FRP/CONCRETE HYBRID STRUCTURAL COMPONENTS FOR WATERFRONT CONSTRUCTION. The Naval Facilities Engineering Service Center (NFESC) is pursuing 6.2 Exploratory research and development proposals for development of cost competitive, long lasting, lightweight, and modular structural components for Navy pier construction, having zero maintenance requirements for 75 years in a severe marine environment. The modularity will facilitate modification of a structure to meet changes in mission requirements over its service life. Concepts should be developed and feasibility demonstrated for construction of waterfront pier and wharf structures, using hybrid concrete and fiber-reinforced polymer (FRP) composite materials. Concepts will maximize maintenance free service life while providing a competitive initial cost. Structures shall meet all operational requirements specified in MIL-HDBK-1025/1, including support for operation of 140-ton mobile cranes and for berthing of major combatants. Optimal performance will be obtained by integrating discrete state-of-the-art technologies such as high-strength lightweight concrete, FRP reinforcement systems, large-scale FRP composite pultrusion technology, and fault diagnostics. This Task will be accomplished in three phases. Phase I will develop structural concepts and characteristics of the materials to be used and the methods of construction. Computer modeling will be initiated to validate feasibility of proposed material characteristics such as bond slip, elastic modulus, tensile strength and ultimate strain. Subsystem structural and mechanical evaluation will be initiated utilizing computer modeling and laboratory testing to perform (1) engineering analysis, (2) conceptual designs, (3) feasibility analysis (4) RDT&E using environmental simulations, (5) evaluation of algorithms, (6)proof of principle demonstrations, and (7) concept demonstrations. Specific areas of interest include (1) sensors for diagnostics and repairs, (2) embedded sensors. PHASE II Milestones will include (1) developing pier/wharf structural concepts with computer models, e.g. load response performance of various concepts for subsystems (load bearing piles, pile caps, beams and decks), (2) performing laboratory test to integrate qualitative diagnostics with selected substructures, (3) determining material constitutive relationships and benchmarking subsystem performance, which will be used to refine and validate computer codes, and (4) procuring one half (1/2) scale pier components. PHASE III will be the construction of a scale pier section consisting of two deck spans and three pile bents at the NFESC Advanced Waterfront Technology Test Site (AWTTS). Testing will include pile driving performance, lateral load response, vertical load response (static creep) and structural monitoring system performance. Testing will determine the feasibility of hybrid construction concepts including the effect of embedded sensors on mechanical behavior, pseudo ductile hybrid system behavior, alkali corrosion of glass composite reinforcement, composite reinforcement anchorage/slip modeling, and material parameter tests and quality control.
