D. Refer to Contract and subsequent modifications thereto, if any, for determination of which of several scheduled alternates have been accepted, and therefore are in full force and effect as though included originally in documents for the Base Bid. E. Notification: Immediately following award of Contract, prepare and distribute to Owner, Architect, Subcontractors and material suppliers, as applicable, a notification of the status of each alternate. Indicate that alternates have been accepted, rejected, or deferred for consideration at a later date. Indicate dates by which Owner must make decisions on deferred alternates in order not to delay project. 1.03 ALTERNATES A.

    M-82 (M0820001.714) Standard Protocol to Evaluate the Performance of Corrosion Mitigation Technologies in Concrete Repairs July 2014 United States Department of the Interior Bureau of Reclamation Denver Federal Center Technical Service Center Concrete, Geotechnical, & Structural Laboratory Denver, Colorado 80225-0007 M-82 (M0820001.714 7-31-2014 Introduction The protocol for measuring the performance of corrosion mitigation technologies for concrete reinforcing steel was first suggested by a group of industry recognized experts and strategic planners in support of goals outlined in Vision 2020: “A Vision for the Concrete Repair, Protection and Strengthening Industry”. Vision 2020 is an industry created strategic plan and roadmap; documents were developed over a several year period which began in 2003. Information about these documents is available at the American Concrete Institute (ACI) Foundation’s Strategic Development Council (SDC) website. One goal of the Vision 2020 group was to develop a test protocol which could be used to evaluate the effectiveness of steel reinforcement corrosion mitigation techniques for existing structures. As a first step toward achieving that goal, a panel of industry experts met to discuss a proposed protocol during the summer of 2008. The panel reviewed and discussed currently available test methods, concrete repair industry needs, and current research programs. The panel stressed the importance of having a flexible test program that would properly evaluate the performance of current corrosion mitigation options while allowing for future innovations. The panel recommended a pilot program be conducted prior to final adoption of a testing protocol or initiation of any full scale testing program to validate the repeatability and reproducibility of the protocol.

  • Research and Applications of Concrete During World War I Vyta
    Engineering the Permanent Material: Research and Applications of Concrete During World War I Vyta Baselice, The George Washington University In 1904, the American Society for Testing Materials produced specifications for manufacturing cement. To test consistency, researchers were instructed to first create a paste by mixing cement with water, form it into a ball with their hands, and then complete the process by “tossing [the ball] six times from one hand to the other, maintained about six inches apart.”1 Resembling cooking rather than industrial manufacturing, early practices of cement testing were deeply inaccurate and unreliable. The making of concrete was similarly inconsistent, involving a haphazard pouring and mixing of various materials whose properties were virtually unknown and quantities poorly calculated. Research and application efforts of concrete during World War I radically transformed the making and testing of this “civilizing medium.” Indeed, American manufacturers reveled in the fact that while the invention of concrete could be traced to Europe, its elevation to a material of ubiquity rested in the expert hands of American researchers.2 Employing wartime scientific advances in geological research, testing, and construction, American scientists learned to engineer the material to build almost anything. This paper argues that the wartime investments that the American government, universities, and businesses made in concrete technologies cemented American dominance of the industry and shaped global knowledge of the material. By examining the work of governmental bodies and science organizations, like the Emergency Fleet Corporation and the National Research Council, alongside that of private players, like the Edison Portland Cement Company, the narrative brings to light the conflict’s transformation of the American concrete industry and its new positioning on the global stage.
