When architects and engineers lack practical knowledge of masonry construction, their designs that look great on paper may be unworkable in the field. Similarly, when masons don't appreciate the engineering and aesthetic considerations involved in a design, they may improvise, unwittingly compromising a building's structural integrity. Better communication before and during construction will lessen the likelihood of costly problems. When confronted with a constructability problem, a masonry crew may fail to inform the designer. Masons may not realize the ramifications of their actions if they alter a design without approval. Designers out of touch with current construction practice also may use details that are obsolete. Either case can cause major problems. If a problem arises on-site from an unworkable design or unclear or missing details or specifications, the masons should alert the foreman, who should discuss the situation with the masonry contractor. Nevertheless, it is far better to nip potential problems in the bud before construction begins by improving communication among project participants. Architects should be aware that many computer aided design (CAD)packages are available that can help ensure good, constructable masonry design. Sometimes a sound, constructable design isn't enough. Architects should make sure their plans and specifications clarify any unusual features in a building. After the design has been executed, it's important to hold a prebid meeting to root out unforeseen problems. Architects also should observe the construction of their work. By being out in the field, architects will acquire more knowledge of construction practices, which will serve them well in future projects.
