PPoster Session, Thursday, June 17Theme F686 - N1123Value Engineering for Nanomaterial Applications in Construction1UJulide DemirdovenUP P*1PDepartment of Architecture, Yeditepe University, Istanbul, TurkeyAbstract - How often have you heard the expression “It’s a great idea, but where has it been done before?” There is considerable interest inacademia, the investment community and among manufacturers about the exciting opportunities offered by nanoscale materials. Although manyapplications for nanotechnology remain theoretical, construction is one area where several applications have already emerged. While current useis limited, the market is expected to approach huge demand within ten years. Can nanotechnology be the reference of the constructionprofessionals in terms of value engineering approach? In this study we are searching for the respond of the question by giving nanomaterialexamples represented in global markets for diversified phases of a project life-cycle. We will briefly look at Tthe highly developing constructionsector in Turkey with contractors operating nationwide as well as abroad.T TA large number of the countries in the region rely on Turkey as amajor supplier of building materials and construction services. There should be a share for nanomaterials. TTDecision makers in the building industry have one goal:deliver a project on time and on budget. They go to greatlengths to avoid any uncertainty that might threaten thisobjective. Their aversion to risk can stifle innovation in thedelivery process. But barriers to innovation may be barriers togood business. Sometimes the parameters of a project crossthe bounds of experience, where traditional methods areknown to be at their limits. In these cases, innovation, with itsinherent uncertainty, may offer a solution with more promiseand less risk [1].Nanomaterial producers promise numerous benefits fromnano-enhanced construction products, including lowmaintenance windows, long lasting scratch resistant floors,super strong structural components, improved longer lastinghouse paint, healthier and safer indoor climates, self cleaningskyscrapers, antimicrobial steel surfaces, improved industrialbuilding maintenance, lower energy consuming buildings andlonger lasting roads and bridges. The use of nanomaterialsallows product manufacturers to offer longer productwarranties. Building owners are expected to enjoy lowermaintenance costs while consumers can look forward tohouses that maintain themselves [2]. Can nanotechnology bethe reference of the construction manager?Value engineering and cost reduction are often confused.The distinction, however, is important. Value engineering is aprocess that considers cost in the context of other factors: life-cycle cost, quality durability maintainabilityCost reduction, on the other hand, considers only first cost.Although tight budgets make cost reductions a fact of life, theowner needs to know exactly what he or she is buying. Valueengineering gives a "better solution," while cost reductions canreduce the quality or quantity of the project to save money. Tobring a framework to the value engineering discussions, theowner sets the criteria with the help of the designer and theconstruction professional. Generally, these criteria fall into afew categories: best cost best function best aesthetic valueDetermining the best cost can be done effectively with a lifecyclecost analysis. Figure 1 shows the design phase of aproject in the life-cycle [3].Figure 1. The four phases of project design.While nanomaterials are already making inroads into certainconstruction applications, many obstacles remain towidespread adoption of this technology, including theconservative nature of construction contractors, thecomplicated nature of building codes and the sometimes toohigh expectations of consumers. In addition, material andmanufacturing costs remain an issue in cost sensitive, largevolume applications while concerns over health and safety arealso at the forefront of discussions. Some suppliers will beable to overcome these factors and establish significantmarkets for nanomaterials in construction applications, whileother products are expected to remain only niche marketcuriosities.TTurkey is primarily self-sufficient in conventional buildingmaterials. However, imported building materials are alsoincreasingly being used, especially in modern world-classhotels, tourist centers, and in the country's more affluentresidential areas.TT TThis study analyzes the market demand ofconstruction professionals for nanomaterials in construction byusing value engieering method. It also considers marketenvironment factors, details industry structure and profiles ofleading industry players [4].*Corresponding author: HTjbozoglu@gmail.comT[1] H. Sommer, Prj.
