Optimum Value Engineering 2008 Page 1 Optimum Value Engineering 1 Optimum Value Engineering (OVE) is the process of comparing alternative materials and methods to determine the least costly combination that will result in the desired end product. A homebuilder regularly practice OVE – accidentally or on purpose – when they select a certain house design and a certain combination of materials and products that they feel will yield the least costly, marketable combination. The OVE techniques to be discussed are centered on wood-frame construction. However, much of the reasoning is applicable to other building systems. As the discussion develops, it will become clear that OVE techniques are not just a collection of ideas. Rather, the OVE approach to home design and construction represents a whole sequence of planning, engineering, and construction techniques that are carefully integrated to work together and to complement each other. It should be recognized that cost reduction could be realized by selecting those OVE techniques that best suit the conditions. Of course there are other ways to reduce the cost of housing. . . 1 NAHB Research Foundation, Inc. Reducing Home Building Costs with Optimum Value Engineered Design and Construction .

Optimum Value Engineering 2008 Page 2 History The OVE approach to home building was developed in the early 1970s by the NAHB Research Foundation, the research arm of the National Association of Home Builders, (now called the NAHB Research Center). The NAHB Research Center was working under a contract from the U.S. Department of Housing and Urban Development as a member of the OPERATION Breakthrough (1969 – 1978) team. As part of its contract effort, the NAHB Research Center constructed a prototype house to illustrate its recommendations. The labor and material requirements of the OVE house were compared to similar requirements for the house if it had been built conventionally. The total direct cost savings of the OVE procedures was more than 12 percent – roughly one-third in labor savings and two-thirds in material savings. The largest portion of the savings (65%) was in the framing, sheathing, and siding materials and labor. Thirteen percent was saved in the foundation system and 11 percent was saved in the mechanical system. The remaining 11 percent of the savings was in a category called “Other”, which included such items as interior trim and paint. The three key principles of OVE home construction are: Modular Dimensioning, Maximize Floor/Wall Ratio, and Use 24” In-line Framing Layout. Modular Planning & Design Modular dimensioning is the most fundamental principle to be observed in OVE design. It requires a thorough knowledge of the standard dimensions of common building materials in order to establish the size and shape of the overall plan in order to minimize scrap and waste and to minimize on-the-job cutting of materials.
