This research was conducted to identify and evaluate the relative importance of the risk factors in equipment highway project in Iraq. Usually, construction projects are affected by risk factors throughout the project life cycle, without identification and allocation categorization of these risks factors the project cannot be succeed, in this paper the open and closed questionnaire used to identify the important risk factors in equipment highway project in Iraq. The research aims to identify the factors that influence the success of equipment highway project in Iraq, to determine the correct response to the risk's factors in this study, (IBM, SPSS, V23) program was used to analyze the main group of risk factors by Mean Score Technique (MS) and ranking from top to bottom. The risk factors of tendering phase analysis by Relative Importance Index (RII) technique then ranking from top to bottom based on their values. The results of this study have conducted that the technical criteria are the most efficient criteria finally, a management criterion with all risk factors that showed in this research will be considered.

Delays and disruption are a common issue in both community and personal building programs The problem exists all throughout the world, but it is particularly prevalent in Iraq, where millions of dollars are squandered each time as a outcome. Delays and interruptions may have serious consequences not just for Iraq's construction plans, but also for the country's economic and social status. While numerous studies have been conducted to investigate the factors driving delays and disruption in Iraqi construction projects, slight consideration has been given to by what means project management implements and approaches have affected the occurrence of project delays and disruption. After analyzing the crucial reasons for delays and instability in public and private construction projects in Iraq, this paper aims to improve the recording and recommendations using Project Supervision concepts. A thorough investigation was conducted to identify the critical factors that are causing delays and disruptions in construction projects in Iraq's public and private sectors and present project management application procedures in order to establish recommendations to successfully reduce work disruptions and instability in Iraq This paper identifies the top crucial factors contributing to construction project delays and disruptions in Iraq. It further identifies project management Tools and techniques that, when used appropriately, have the potential to address the major causes of delays and interruptions. Following that, a new set of guidelines for applying Project Management methodologies and strategies to address the identified delay and disruption issues is provided, with the objective of aiding practitioners in minimizing the possibility for construction delays and interruption in Iraqi projects.

Many countries have noted economic expansion and advancement in the construction industry, and the key prerequisite to realizing its current potential is the construction of taller and deeper structures. On the other hand, the development of millions of tons of construction waste per year is an issue that is growing at a similar rate. This volume of construction trash contributes to numerous environmental issues around the world. The tremendous rise of Iraq's building industry during the last few decades has been witnessed. This rapid growth is resulting in a massive amount of construction and demolition debris. This paper proposes a theoretical method for calculating the trash generation rate of building and demolition projects using accessible data, and it is offered as a less complex and more generally applicable alternative to hand sorting and weighing debris on site. In a case study in Iraq, the method is used for ten projects. The trash generation rate was determined in this study, with a waste generation rate of 26.91546 (t 100 m-2) for standard construction methods and (t 100 m-2). Although it is difficult to predict the exact amount of construction and demolition waste generated in the future, the results show that the amount of waste generated in the year 2032 will be 16795179 (ton/year), indicating the need to develop a prior plan to properly manage construction and demolition waste.

The concrete constructions complicated, expensive, and exposed to risk due to several factors like environmental, design and construction, lead to appear many methods use to re-habitation concrete structures such as the technology of ferrocement sections, the technology of steel sections, the technology of Fiber Carbon Reinforced Polymer (FCRP) and the technology of nano-materials. This paper came to determine the best way to re-habitation damaged concrete beams by comparing among four methods used in Iraq. The questionnaire form is distributed to 100 professional engineers in the construction and project management field to determine the method they prefer and advise using it in terms of strength, effort, time, and cost. The result explains more than half of the test sample prefers to use the steel section technology because it gives the strength at a reasonable time, appropriate cost and they have a lot of practical experience using it.
