202

4.3.3.6 Other Institutions

Other notable institutions are the American Institute of Steel Construction (AISC), the Prestressed Concrete Institute (PCI), the Portland Cement Association (PCA), and the Transportation Research Board (TRB) of the National Research Council. They publish manuals and professional journals on concrete and steel technology that present state-of-the-art design methods and construction projects.

4.3.3.7 Federal Highway Administration

The Federal Highway Administration (FHWA) is a branch of the U.S. Department of Transportation and is located in Washington, D.C. with so-called field offices all over the nation. It is fulfilling its mission of creating and maintaining high-quality transportation systems in several ways. The following brief summary is based on information provided by the Federal Highway Administration on its site on the World Wide Web (FHWA 1999).

A main area of FHWA activities is provision of technical expertise for design, construction, and maintenance of transportation projects through close cooperation with regional and local authorities. To support this work research projects are undertaken, e.g. in advanced technologies for supervision of traffic. Secondly, the FHWA supervises federal funding for transportation projects and sets up regulations for such projects. In case of natural disasters and other major incidents in the transportation systems the FHWA assists with investigation and repair works. The FHWA also develops regulations and guidelines for construction projects that are related to public transportation.

Apart from regulatory work the FHWA is also active in the field of training and educating professionals in transportation issues, such as safety, economy, and protection of the environment. An example for training is seismic bridge design, which the FHWA conducted to improve safety of bridge structure in case of earthquakes. The very large variety of programs that the FHWA sponsors shows the involvement of this institution in bridge construction.
