Abstract - How often have you heard the expression “It’s a great idea, but where has it been done before?” There is considerable interest in<br />

academia, the investment community and among manufacturers about the exciting opportunities offered by nanoscale materials. Although many<br />

applications for nanotechnology remain theoretical, construction is one area where several applications have already emerged. While current use<br />

is limited, the market is expected to approach huge demand within ten years. Can nanotechnology be the reference of the construction<br />

professionals in terms of value engineering approach? In this study we are searching for the respond of the question by giving nanomaterial<br />

examples represented in global markets for diversified phases of a project life-cycle. We will briefly look at Tthe highly developing construction<br />

sector in Turkey with contractors operating nationwide as well as abroad.T TA large number of the countries in the region rely on Turkey as a<br />

major supplier of building materials and construction services. There should be a share for nanomaterials. TT<br />

Decision makers in the building industry have one goal:<br />

deliver a project on time and on budget. They go to great<br />

lengths to avoid any uncertainty that might threaten this<br />

objective. Their aversion to risk can stifle innovation in the<br />

delivery process. But barriers to innovation may be barriers to<br />

good business. Sometimes the parameters of a project cross<br />

the bounds of experience, where traditional methods are<br />

known to be at their limits. In these cases, innovation, with its<br />

inherent uncertainty, may offer a solution with more promise<br />

and less risk [1].<br />

Nanomaterial producers promise numerous benefits from<br />

nano-enhanced construction products, including low<br />

maintenance windows, long lasting scratch resistant floors,<br />

super strong structural components, improved longer lasting<br />

house paint, healthier and safer indoor climates, self cleaning<br />

skyscrapers, antimicrobial steel surfaces, improved industrial<br />

building maintenance, lower energy consuming buildings and<br />

longer lasting roads and bridges. The use of nanomaterials<br />

allows product manufacturers to offer longer product<br />

warranties. Building owners are expected to enjoy lower<br />

maintenance costs while consumers can look forward to<br />

houses that maintain themselves [2]. Can nanotechnology be<br />

the reference of the construction manager?<br />

Value engineering and cost reduction are often confused.<br />

The distinction, however, is important. Value engineering is a<br />

process that considers cost in the context of other factors:<br />

life-cycle cost,<br />

quality<br />

durability<br />

maintainability<br />

Cost reduction, on the other hand, considers only first cost.<br />

Although tight budgets make cost reductions a fact of life, the<br />

owner needs to know exactly what he or she is buying. Value<br />

engineering gives a "better solution," while cost reductions can<br />

reduce the quality or quantity of the project to save money. To<br />

bring a framework to the value engineering discussions, the<br />

owner sets the criteria with the help of the designer and the<br />

construction professional. Generally, these criteria fall into a<br />

few categories:<br />

best cost<br />

best function<br />

best aesthetic value<br />

Determining the best cost can be done effectively with a lifecycle<br />

cost analysis. Figure 1 shows the design phase of a<br />

project in the life-cycle [3].<br />

Figure 1. The four phases of project design.<br />

While nanomaterials are already making inroads into certain<br />

construction applications, many obstacles remain to<br />

widespread adoption of this technology, including the<br />

conservative nature of construction contractors, the<br />

complicated nature of building codes and the sometimes too<br />

high expectations of consumers. In addition, material and<br />

manufacturing costs remain an issue in cost sensitive, large<br />

volume applications while concerns over health and safety are<br />

also at the forefront of discussions. Some suppliers will be<br />

able to overcome these factors and establish significant<br />

markets for nanomaterials in construction applications, while<br />

other products are expected to remain only niche market<br />

curiosities.<br />

TTurkey is primarily self-sufficient in conventional building<br />

materials. However, imported building materials are also<br />

increasingly being used, especially in modern world-class<br />

hotels, tourist centers, and in the country's more affluent<br />

residential areas.TT TThis study analyzes the market demand of<br />

construction professionals for nanomaterials in construction by<br />

using value engieering method. It also considers market<br />

environment factors, details industry structure and profiles of<br />

leading industry players [4].<br />
