Explanation and Spatial Analysis of Causes and Consequences of Construction Infractions Case Study: Zahedan City

Introduction and Background: Construction violations are one of the problems in cities and especially metropolitan developing cities, which cannot easily be solved with an inefficient management system. Aims: The purpose of this study was to evaluate the existing situation and the distribution of this phenomenon in Zahedan city with the aim of the pathology of construction and construction violations in the city of Zahedan. According to the studied components and applied nature, the method of this research is descriptive-analytic. The required information is gathered with two methods including literature and library research (books, statistics, and maps) and field study (review of cases of violations from 2005 to 2014). One of the objectives of this research is to show the pattern of dispersion of violations in the city and the leveling of neighborhoods and urban regions. This pattern has been determined using the mean of the nearest neighbor of the distribution pattern of violation. Then, by means of the weighted average model geographical distribution of the neighborhoods, and with the Coopers model, ranking of neighborhoods in the number of violations of construction in the neighborhoods is specified. Finally, GIS software has been used to draw maps. The results show that construction violations in Zahedan are not caused by poverty and in marginal settlements, but also in neighborhoods and legal settlements, and by more people who have sought to escape the law and economic profit. Based on the drawings of the dispersion of construction violations in the city of Zahedan during the 10 year period (2005 - 2014), we find that the first violation was first in region 5, but with the construction of the beautiful city region, construction violations have risen stage by stage and at the end of studied period, district 5 has the most violations. It is noteworthy that 2nd and 3rd municipalities district during the entire year showed similar violations, and since the beginning of the year until 2005 there have been no significant changes in terms of decreasing or increasing violations.
