Tez notu: ABSTRACT Due to the increase in the needs of new housing that is caused by the huge increase in population around the world, and with the seeking of nations toward sustainability and green buildings, a need of new construction techniques to facilitate the construction of sustainable building is a must. Different techniques have been developed and still developing with the time. Three techniques have been considered in this study, 3d concrete printing technique, bricklaying technique and the traditional conventional construction technique. A case study of a simple house have been also taken into consideration in order to differentiate which of the available techniques nowadays is the best. This study covers three different aspects in comparison. The first aspect is time management and the time needed for each technique to finish-up the same building, the second part is the cost analysis where the cost needed for each technique is considered, and in the last part an environmental study have been carried out to check greenhouse gases emissions of each technique. In this thesis a notable results have been shown after doing the three types of studies, in what concerns time 3D printing technology took the first place between the techniques while brick laying technique took the second place for the construction time, and at the last place the traditional technique took the most time needed for the building to finish. For the pricing and cost analysis that have been studied the placing of the three techniques have not changed 1st the 3D printing technique, the 2nd is the brick laying technique, and the last with the most expensive construction technique is the traditional technique. In what concerns the environmental impact the distribution of the construction techniques with the least emissions to the highest are respectively as follows, brick laying construction technique, 3D printing technique, and the traditional construction technique. 3D printing construction technology will take the construction industry into a new level that will assure the availability of a new construction technique that has sustainability priority, using 3D printing technology will improve the construction techniques by reducing the time of construction, the cost of the construction, and the less emissions possible during construction. Key Words: Construction Techniques, Technology, 3D Printing, Sustainability, Environmental Impact, Cost Analysis, Construction Management, Brick Laying.
