At the end of 2019, the whole world was exposed to a major health crisis, which the Coronavirus, which went out of the control of all countries, including Iraq, The negative impact of the coronavirus pandemic continues to this day on the construction industry sector in Iraq. This research aims to study and find the most common risk factors for the...

The process of formulating the basic strategies in a construction project must go through a set of stages. The desired objectives in feasibility studies should be highlighted to ensure that the packages of the infrastructure projects are moving smoothly in terms of the desired goal. In order to meet ambition for the long term in infrastructure proj...

During sewage projects, management appears Hydrogen sulfide (H2S) emission-related odours have been a problem in sewage project networks for decades. One of the gases that directly harms employees and network infrastructure is hydrogen sulfide gas. Using the TOXCHEM software, the network of the Al-Hur project in Karbala, south of the Iraqi capital,...

A feasibility study is considered a strategic tool, a critical principle, and an essential stage of the success of the investment project, and it is regarded as an essential point in the success or failure of the investment project. Therefore, feasibility studies are among the most critical elements of the success of investment projects. The purpos...

Feasibility studies and their effects on the success or failure of investment projects. "Najaf governorate as a model" Abstract: A feasibility study is considered a strategic tool, a critical principle, and an essential stage of the success of the investment project, and it is regarded as an essential point in the success or failure of the investme...

Gibbs measures based on 1d (an)harmonic oscillators as mean-field limits Abstract: Iraq is experiencing many challenges that affect infrastructure performance and the construction industry's development. The current emergency of the Corona pandemic and the recent economic downturn will have a severe impact on construction projects. This research ai...

A crisis is a sudden condition that occurs due to unforeseen adverse events or problems. Crises affect all aspects of life, including the construction industry. The construction industry is unique, influenced by many factors, making them subject to multiple situations due to the long implementation period and the diversity of stages, from the decis...

Iraq is experiencing many challenges that affect infrastructure performance and the construction industry's development. The current emergency of the Corona pandemic and the recent economic downturn will have a severe impact on construction projects. This research aims to undertake an analytical study of the Iraqi construction sector to learn more...

Construction projects are known globally as risky projects because construction projects are subject to a high degree of uncertainty from achieving the final objectives of the construction project. The process of risk identify, analysis and management is one of the practical and fruitful methods used in the direction of construction industries to i...

Most construction projects are exposed to multiple external and internal problems and obstacles that lead to a crisis within the construction project, which may lead to the failure of the construction project. It is also a source of concern for owners, stakeholders, and contractors alike due to its difficulty. As a result, a new approach to dealing...

Iraq is witnessing many ongoing crises that have affected the performance of the infrastructure and the development of the construction field. Therefore, it is necessary to devise and develop effective crisis management strategies during the three phases of crises before, during, and after the crisis, which makes the development of such a system ex...

The purpose from the research to choose the correct and best type of cement that is prevail able by mass quantity in the markets and different types. To construction the infrastructures needs the best types but the worthy mentioned the world specifications depend on compressive strength after (28) days that means the target to recognize the cements...

Any construction project through several stages, starting from the feasibilitystudy stage to the project delivery stage, as the most critical stage that must be focused on is the design stage. It was essential to adopt modern and advanced programs at the design stage to avoid problems and claims between the employer and the contractor due to change...

Construction productivity is the main indicator of the performance of construction projects for any country. The productivity of construction projects is defined as the output of the system for each unit of input. The main objective of this paper is to identify and analyze factors affecting labor productivity in construction projects in Iraq throug...

Construction sites are among the most dangerous construction industries in terms of exposing the safety and health of workers to various dangerous accidents during the construction process. Where the statistics of the International Labor Organization show that there is one death every three minutes as a result of a work injury and that there are fo...

This paper compares between three image compression Discrete Cosine Transform (DCT) and Wavelet Transform (Haar, DB), and combines the two of them. The new block incorporates the DCT benefits in which it functions flawlessly with highly correlated data. In addition to, the benefits of the transformation of Haar that provide preferable ends for imag...

The productivity rate is the main indicator for the development of construction projects for any developed country. The main goal of this paper is to evolve a mathematical model by using the multiple linear regression technique to predict the rate of production of concrete column molds. This is because the currently used methods in estimating produ...

Productivity is a very important element in the estimation process in construction management. The objective of this research is to identify and analyze the factors which affect labor productivity in construction projects. In this research, 42 effective factors were collected from site survey, interview with engineers and experts, and previous rese...
