Strength of concrete is a primary criterion in selecting this material for particular application. This construction gains strength over long period time after pouring. Characteristic normal that considered structural design defined as the compressive sample has been aged 28 days. Rapid and reliable prediction would be economically practically great significance. Therefore; an active area research considerable number studies have carried out. In study, two techniques were used to propose...

Building Information Modeling (BIM) is a unified and comprehensive system for all that associated with the construction project, which includes set of effective policies, procedures, computer applications increase level performance in project during its life cycle.Through this study investigate about potential barriers facing adoption BIM was performed.The quantitative approach adopted by conducting questionnaire directed to professionals field projects public private sectors.Three hundred...

Soil stabilization is one of the processes that have used widely to enhance pavement structure. Using natural and man-made resources as efficiently possible while inflicting little environmental harm known sustainable roadway building. Reducing energy consumption during construction making optimal use materials reduce waste are two approaches make roads more sustainable. This project work concern in chemical soil with a or by-product material. The experiential included improve sandy by using...

Due to the large population of motorway users in country Iraq, various approaches have been adopted manage queues such as implementation traffic lights, avoidance illegal parking, amongst others. However, defaulters are recorded daily, hence need develop a mean identifying these and bring them book. This article discusses development an approach recognizing Iraqi licence plates that queue management systems identified. Multiple agencies worldwide quickly widely recognition vehicle license...

The flood caused by the heavy rainfall during July and August 2022 in Balochistan led to massive widespread damage infrastructure lifelines. A total of 6953.83 km roads 435 bridges were damaged Pakistan. To prevent such losses create a climate-resilient transport system creating strong enough endure various natural challenges with minimal harm swiftly recover their functionality, this study used data from 35 flood-affected as case patterns relationships between disaster bridge failure...

As built documentation provide critical information that is needed during and afterward the construction. This process serve as a foundation upon which all changes, modifications or otherwise, made construction so it can quickly obtain about any design change. After construction, ready source what was actually built. Conflicts of documents with crucial aspect projects in order to prevent excessive cost delays work correction operation maintenance renovation phases. Traditional method...

Cost estimation and prediction are crucial processes for the success of construction projects, especially infrastructure development. This study analyzes historical data collected between 2011 2023 investigates relationship elements final cost highway projects in Iraq. Different analysis approaches, including statistical assessment machine learning techniques, were applied to a dataset 291 projects. is time-consuming risky process that requires many qualitative quantitative parameters be...

Building Information Modeling (BIM) is an integrated and comprehensive system for all that related to the construction project, which includes a set of effective policies, procedures, computer applications increase performance project during its life cycle. The objective this research develops clear concept about BIM adoption in Iraq through investigating potential benefits can be obtained application projects also build measurement model these benefits. methodology was based on quantitative...

The construction industry is subject to a high level of risks and uncertainties than any other industry. In reality, most participants experience cost time overruns often fail meet quality standards operational requirements. This paper aimed investigate the accuracy artificial intelligent models such as Extreme Learning Machines (ELM) demonstrate impact risk factors on predicting delay projects. Risk (RF) (DF) were identified analyzed using Probability Impact analysis adopted model's inputs....

Information technology and its application have resulted in enormous development the construction industry during last decade. The main reason behind this evolution was incorporation of Building Modeling (BIM) to be an inefficient approach. BIM is now globally considered tool transforming process new era. It also as a good for whole project lifecycle. aim present study clarify how can used after within uncertainty risky environment such document losses unrecorded change orders. Interviews...

Construction project delay is a global phenomenon. The risk being regarded as main challenge that tackled via the firms of construction. It possessed an inverse effect upon performance resulting in cost overruns and productivity reduction. In Iraq, most construction projects surpassed their prearranged time were delayed, loss income. objective this paper was to predict illustrate risks effects by using artificial neural networks with particle swarm optimization method (ANN-PSO). Thereby,...

In a construction project, especially in risky environments, subcontractors are considered as important the main contractor since most work is carried out by them.A crucial step building projects choosing finest subcontractor.When subcontractors, variety of considerations must be taken into account.A poor choice might cause lot issues when job being done.These include subpar and project length delays.Many things influence this process.From earlier studies, variables that affect subcontractor...

The aim of the present quantitative assessment phytoplankton community along Garmat-Ali River and to establish its relationship with physical chemical factors based on changes occurring in aquatic environment Basra Governorate, including decreasing fresh water, this is due low discharge water coming from upstream countries, rise temperatures global warming, increased salt concentrations other factors. Four locations were chosen region: Al-Najibiya, Al-Mashhab, Al-Salal Al-Nagara station....

Lightweight foamed concrete brick is new construction materials. It gives a prospective solution to building industry, this research aims study the cost, dead loads, environmental issues and energy consumption from using lightweight foam bricks as materials by utilizing information modeling technique. The results obtained modelling proved that cost of work units grade A (2000 kg/m3) B (1800 kg/m3 ) higher (19.4% 11.9%) respectively than activity traditional fired clay bricks. For C (1600 was...
