AMM provides exclusive news and pricing information for the ferrous and nonferrous metals markets with a focus on North America and world markets where applicable. Working with PTI and CRSI, AMM publishes price indicators on its website designed to reflect the relative price movements in three grades of steel: rebar, low carbon rod (used for mesh) and high carbon rod (used for prestressing strand.) The higher the number, the higher the price of the steel. The value of 100 represents the average price over an 18-month period from March 2007.
American Segmental Bridge Institute (ASBI)
ASBI was incorporated in 1989 as a nonprofit organization to provide a forum where owners, designers, constructors, and suppliers can meet to further refine current design, construction and construction management procedures, and evolve new techniques that will advance fhe quality and use of concrete segmental bridges.
The National Concrete Bridge Council is a council of allied industry organizations dedicated to: promote quality in concrete bridge construction; gather and disseminate information on design, construction, and condition of concrete bridges; establish communication with federal and state departments of transportation, city and county public works departments, and consulting engineers, and provide information on behalf of the concrete industries to codes and standards groups.
PTA's objectives are to: 1) promote the use of post-tensioning in buildings, bridges, silos and tanks, ground floor slabs and other structural types throughout the UK construction industry, 2) promote best practice in the design, procurement and execution of post-tensioned structures, 3) support and take part in research and development to improve the efficiency and technical capabilities of post-tensioning, 4) support high quality in PT construction through the CARES QA scheme and other relevant bodies, and 5) support safe working practices throughout the UK PT industry and to maintain high levels of training.
PTIA was formed to represent the post-tensioning contracting industry in Australia, seeking to maintain a viable and competitive industry with high standards in design and construction of post-tensioning systems for the benefits of its Members, their employees, and their clients.
SAPTA was formed in 1987 as an employer body..."to promote the interests of its members, to encourage fair and equitable trading conditions and to establish optimum standards of workmanship and service in order to preserve the good name of highly technical and sophisticated post tensioning industry."
