- Description
- This announcement constitutes a Broad Agency Announcement (BAA) for the Naval Facilities Engineering Service Center (NAVFAC ESC) under FAR 6.102(d)(2). This announcement is open until 1 June 2009 in which NAVFAC ESC is seeking technologies and methodologies to prevent concrete deterioration from alkali silica reaction (ASR). ASR has resulted in significant damage to Department of Defense (DOD) airfield pavements, with expenses in the tens of millions of dollars at each airfield. So far over 30 airfields have reported significant problems. While mitigation of existing ASR deterioration may be considered, the main emphasis of this announcement is on prevention of deterioration. Work under this award will be conducted in up to five (5) phases, with each of the phases costed and negotiated separately, and lasting approximately not more than one year each. All five phases may not be awarded nor may all phases be awarded in consecutive order. The announcement for this award is for abstracts only, of approximately five (5) pages or less of technical material. The abstracts will outline the topic(s) of interest selected and the phased approach proposed. The abstract may be supplemented by resumes and list of publications relevant to this announcement which will not count against the five (5) page limit. The initial award will be made for Phase I only and is estimated for up to $100K. Abstract emphasis should be on the proposers Phase I effort with subsequent phases identified more broadly. Multiple awards may be made under this announcement. Topics of interest described below are provided as guides to areas that may be included in your abstract for the various phases. It is not expected that any individual abstract will include all topics, nor is it expected that abstracts limit their approach to only the areas specified in the topic list. Individual topics of interest are as follows:(a)Develop a methodology for determining the suitability of fly ashes with high calcium oxide contents to prevent concrete ASR deterioration. Current DOD guidelines limit fly ash usage to Class F ashes with additional limits on their composition. Recent DOD research had shown that Class C ashes close to Class F ashes could be used, but further assessment of effects of the deleterious components in Class C ashes is needed.(b)Recent DOD research has shown the effect of fly ash chemical composition on its effectiveness to prevent ASR. However this research was limited in terms of the available data and needs further validation using a wider sample of U.S. sources, as well as sources from contiguous geographical areas.(c)Class N natural pozzolans and calcined clays have also shown effectiveness in mitigating ASR. However, some pozzolans may not be as effective as fly ashes with similar chemical composition. Further assessment of pozzolans is needed.(d) Ground granulated blast furnace slag (only grades 100 and 120 are considered) can be effective in preventing ASR, but at higher replacement amounts than fly ash. Unlike fly ash, slag can be efficient at preventing ASR even at high CaO contents. Hence further investigation into slag effectiveness based on chemical composition, which is different than for fly ash, is needed.(e) For both fly ash and slag, effectiveness in preventing ASR may also be linked to mineralogy, not just chemical composition. Further assessment of mineralogy and its potential effect on current assessments based on chemical composition are needed.(f) Fly ash fineness has been shown to be a significant factor in preventing ASR. Fineness needs to be combined with chemical composition to develop a joint metric for effectiveness.(g)Since both fly ash and slag can prevent ASR, combinations of both are expected to be effective as well, and this is reflected into current DOD specifications. Such binary (or tertiary) blends can also improve the concrete strength gain rate. Further correlations between ash content, slag content, and concrete strength gain rate are needed. (h)ASTM C 1260 and C 1567 are currently used by the DOD to prevent ASR. The DOD expansion threshold was initially 0.08% at 14 days, which is more conservative than ASTM recommendations, but recent research suggests that 0.08% at 28 days would be more representative of actual field behavior. Further insight into this lower threshold and its attainability with supplementary cementitious materials (SCMs), as well as comparison with other field or test data (e.g. ASTM C 1293 at 2 years) are sought.(i)Recent efforts by FHWA, FAA, and the Army are looking at the effectiveness of lithium nitrate topical applications to mitigate existing ASR. Assessment of lithium nitrate application would enable the determination of this methods ability to control expansion, and, in particular, the determination of the cost-effectiveness of topical lithium applications versus pavement replacement. (j)Rubblization and crack and seat technologies at ASR affected airfields as alternative cost effective repair/reconstruction techniques (to removing and replacing) need to be evaluated. These techniques involve cracking or breaking the existing concrete into small particles and overlaying with asphalt. However, the effects of continued deterioration and expansion of the cracked ASR-affected concrete need to be evaluated before these techniques can be used. A NAVFAC ESC technical review board will evaluate the abstracts to this BAA. The abstracts will be evaluated based on the following CRITERIA (listed in descending order of importance): (1) the scientific/technical merits and objectives of the abstract; (2) the contractor's capabilities related experience, techniques, or unique combination of these that are integral factors in achieving the contractor's proposed objectives; (3) the qualifications, capabilities, and experience of the principal investigator, team leader, or key personnel who are critical in achieving the objectives of the abstract; (4) the cost relative to the proposed scientific/technical approach, and (5) the applicability of the conclusions to guidance and criteria. Subsequent to review, the NAVFAC ESC technical Board may request a full scale Proposal of no more than 25 pages. NAVFAC ESC may share the abstracts and the proposals with other DOD personnel of offices associated with this topic. Information that is sensitive or proprietary must so be marked page by page in the abstract and or proposal. Multiple awards may be made. The request for a proposal does not obligate the government in awarding a contract. CRITICAL NOTE: A CONTRACTOR IS REQUIRED TO REGISTER WITH THE DEPARTMENT OF DEFENSE CENTRAL CONTRACTOR REGISTRATION (CCR). NO CONTRACT AWARD WILL BE MADE TO ANY CONTRACTOR THAT IS NOT REGISTERED OR IN THE PROCESS OF REGISTERING WITH THE DOD CCR. THE DOD CCR MAY BE REACHED AT (888) 227-2423, OR WEBSITE WWW.CCR.GOV. THERE IS NO COMMITMENT BY THE NAVY EITHER TO MAKE ANY CONTRACT AWARDS OR TO BE RESPONSIBLE FOR ANY MONEY EXPENDED BY THE CONTRACTOR BEFORE A CONTRACT AWARD. Any information that may be sensitive to review by such personnel should not be submitted. Eligibility notification will be sent to all contractors, who have submitted an abstract, after the Navy's Technical Evaluation Board (TEB) has reviewed all abstracts submitted by an internal periodic cut-off date. The internal periodic cut-off date may occur several times within the period from the BAA announcement to the closing date for receipt of abstracts. Abstracts may be submitted at any time but to ensure review by the first meeting of the Technical Evaluation Board (TEB) abstracts should be received by July 31st, 2008. Abstracts received after this date will be evaluated by subsequent meetings of the Technical Evaluation Board (TEB) with such subsequent awards being made dependant upon results of evaluations and budgetary constraints.

Packages shall be mailed via USPS, UPS, or Federal Express, to: NAVAL FACILITIES ENGINEERING SERVICE CENTER,CODE Business Office 08, ATTN: N. J.
