In scarcely more than ten years, mass production of prefab forms has brought new speed and economies into the construction industry. The reasons for turning to prefab forms are obvious. The need for speed was a major factor. Building forms on the job site requires lots of time- time the contractor could be using to superintend the job. Prefabs also permitted a contractor to start a job much faster. An even more compelling reason for the industry to turn to prefabs was economy. Jobs had to be figured close, and prefabs permitted labor saving short cuts immediately. Forming hardware was also beneficiary of the trend to fast erection and stripping. Even scaffolding and bracing became prefabricated so that the contractor need spend no time at all on this otherwise time consuming detail work.
