Integrated Building System

The procedure for erecting building structures has changed during the past few years. Field work requires workers to perform complicated tasks in a highly dangerous environment. There is a need to develop new technology to protect workers from the dangerous job environment and emphasize cost-efficiency, especially in the construction of multistory structures with repeated cycles.

The Integrated Building Systems program was developed to coordinate research projects in automated construction and connection systems. The objective of this technology is to design, fabricate, erect, and evaluate cost-effective building systems with a focus on providing a computer integrated approach to these activities.

A family of structural systems, beam-to-column connections, in both concrete and steel, will possess the capability of being erected by automated construction techniques. The technology for automated construction is heavily dependent on the use of platform cranes which are controlled by a system of six cables to allow precise movement in six directions.

The emphasis of these new designs is on cost-efficient fabrication as well as geometric configurations which provide an automatic self-guided erection feature to greatly facilitate initial placement. This feature will minimize human assistance during construction and will result in quicker, less expensive erection procedures in which workers are less susceptible to injury or fatalities.

A model building frame was developed as a case study to compare the Integrated Building system to conventional construction. Based on the results, the range of projected cost savings was between 9% and 12%. A consortium of government, industry, and university partners is envisioned as the most effective mechanism to move these technologies from the laboratory to the field.
