Buffers are often used in Construction to prevent the negative impact of Variability and Uncertainty on projects. Inventories of materials, budget contingencies, time float, and excess of equipment capacity are examples of the type of Buffers found in construction. However, usually the design and management of Buffers is based mostly on intuition and performed informally. New production philosophies such as Lean Production, Lean Construction and Theory of Constraints allow a more systematic and rigorous approach to the Design and Management of Buffers. This paper discusses the role of production management philosophies in the Design and Management of Buffers, and how selected IT tools can support this process. The paper also provides some guidelines for the design of Buffers in repetitive construction projects using a proposed conceptual model.

This paper presents research results that describe how value generation can be improved in the design process of industrial projects when using computer advanced visualization tools CAVT. The CAVT concept definition, prior studies about impacts of CAVT, and why they are not sufficient are presented in the paper, supporting the assertion that the extensive attention to technology instead of to the context of technology application and the lack of a conceptual framework has prevented some prior research about CAVT impacts to truly focus in ideas about how to improve engineering and construction processes. Combining production theory and lean construction principles with information technology IT, a framework for understanding the impacts of CAVT developed as part of the research is proposed. Illustration of the use of the framework in a case study and research validation activities leads to analytic generalization of the research results.
