This paper covers the latest developments in the preparation of design guidelines, construction specifications, and inspection and quality control recommendations related to the use of composites in construction. The forms of FRP composites addressed are limited to bars and laminates for reinforcement of concrete and masonry structures (new construction and repair/rehabilitation). FRP bars are being used as the internal reinforcement in concrete members when the conventional steel bars may be undesirable for a host of reasons (e.g., corrosion), and principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). Conversely, strengthening of concrete members with externally bonded FRP composites in the form of laminates or near surface mounted (NSM) bars can now be considered an "acceptable practice". Also in this case, the design and construction principles for use in practice are being finalized by ACI. The drivers for FRP strengthening technology are several, but perhaps the most relevant one is the ease of installation. On the wave of historical structures restoration projects conducted in Europe, there is an increasing interest in masonry-type applications even though no institution-sanctioned guidelines are available at present.
