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 />
