Cities are like books; they can be read, and we have to understand their language. The street, the footpath, the square, and the parks are the grammar of the city; they provide the structure that enables cities to come to life, and to encourage and accommodate diverse activities. A humane city creates pleasure for visitors and passers-by, as well as for those who live, work, and play there every day. Everyone should have the right to easily access public open spaces; everyone should be able to see a tree from their window, or to sit on a bench close to their home with a play space for children, or to walk to a park within ten minutes. Well-designed cities inspire the people who live in them, whilst poorly designed ones brutalize their citizens. A city must increase the quantity and quality of well-planned beautiful public spaces that are human in scale, sustainable, healthy, safe, and lively. In this approach, this research studies the relation between the human social behavior as a valuable concept and the urban design theories that will help improve the lack of understanding of what people need for space and how urban designers can stimulate a better urban public place. It then goes on to emphasize the importance of urban qualities of these spaces for conveying human behavioral social activities in public spaces. Critically, this social function often conflicts with understandings of public spaces, which emphasize their place in promoting a city's image, consumer activity, and economic renewal. The research will be conducted over three parts: the human social behavior approach as a new dimension from definitions, models and personalization; public urban space design throughout time, place, and space configuration; and the linkage between the theory and practice of people in the conclusion of the research.

During last decades, the aim of new technologies was to develop new information systems to automate manual processes. Large-scale projects in the field of construction industry need a different approach to organize and analyze data creating a database without any duplication or redundancy. Building Information Modeling (BIM) is a teamwork process using advanced technologies to generate data modeling. Based on a literature review, the present research proposes a set of hypotheses that links BIM implementation with the enhancement of information sharing capability (ISC) and collaborative decision capability (CDC) in the construction sector of the building industry. Consequently, it relates the degree of BIM use to the design quality enhancement using ISC and CDC as mediators. Towards this end, the research adopts three sets of criteria namely, functionality, form and aesthetic values, and building construction quality as indicators to design quality improvement. Finally, the research proposes a new conceptual model to set the potential relations between the different variables included in the study. Hence it offers several implications for practitioners and decision makers concerning the importance of BIM to enhance the design quality.
