Background: Construction and architectural projects(CAPs) play a significant role in the economic development of most countries. The construction industry in Egypt has significantly grown in recent years. Due to this growth, the number of occupational accidents in the country’s construction industry has also increased. Methods: This study aimed to assess the Occupational Safety and Health(OSH) field. Then, the assessment effects on the construction project quality are evaluated. The statistical analysis of the question naire surveys conducted on project safety, quality, and executive management at construction companies based on the Statistical Package for the Social Sciences(SPSS). Results: After comparing two sites, the research results indicated differences in completion times and overall costs between the two sites.70% of the respondents agreed that the completion times, costs, and project qualities vary between the two sites. About 92% of the sample completely agreed and were willing to follow the international laws, which stipulate the principles of OSH in construction sites. They also agreed that there should be an increased understand in gof the importance of OSH management in sites, which can help prevent clashes between the two departments. Conclusions: Companies should hire a social worker to take care of the workers, help them solve their problems, and ensure that safety standards are being met in the construction sites. In addition, regular medical examinations of all workers must be conducted to ensure that the yare free from any occupational, non-infectious, or infectious diseases, such as the coronavirus.

Risk analysis of construction of administration projects using Bayesian networks

PurposeThis paper aims to enlighten the importance of the risk management process which is considered as a major procedure to effectively handle the potential inherent risks in the construction industry. However, most traditional risk analysis techniques are based on theories that deal with each risk factor as an independent, which does not take into consideration the causal relationships between risk factors.Design/methodology/approachThis study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using Bayesian belief networks (BBN). Through a review of the literature, 27 risk factors were identified and categorized as the most common risk factors in the construction industry. A structured questionnaire was performed to estimate the probability and severity of these risks. Through site visits and interviews with experts in the construction field, 200 valid questionnaires were collected. A risk analysis model was developed using BBNs, then the applicability of this model was verified using a case study in Egypt.FindingsHowever, the outcome showed that critical risks that manipulate administrative construction projects in Egypt were corruption and bribery, contractor financial difficulties, force majeure, damage to the structure and defective material installation.Practical implicationsThe proposed study presents the possibilities available to the project parties to obtain a better forecast of the project objectives, including the project duration, total project cost and the target quality by examining the causal relationships between project risks and project objectives.Originality/valueThis study aspires to identify the overall risk of the administrative construction projects in Egypt and to recognize the most influencing risk factors through the project life cycle by using BBNs.

Developing a user plug-in to assess delay causes’ impact on construction projects in Egypt

There are three main criteria that account for a construction project’s success: completion on-time, within budget, and following the specifications. Nowadays, construction projects are facing various problems where delays are considered major one of them, particularly in Egypt. Analyzing construction delay causes while attempting to mitigate their impact is a matter of crucial importance. That’s why a program was developed to help the user assess the delay causes’ impact with respect to the project’s concerned activities. Besides, it was designed to identify the potential mitigation measures according to the delay cause type. The Building Information Modeling (BIM) was the platform used to carry out such analysis. Thus, the main objective of this study is to investigate the delay causes’ effect on the project’s duration and cost. This was achieved by analyzing the concerned activities’ affected duration and cost, according to the selected delay cause and its associated mitigation measures, by means of a developed user plug-in. Then, duration/cost summary tables were presented for the user to highlight the main findings in terms of delay and saving impact. The attained results were considered important indicators to be referred to for similar cases throughout the project progress. Apart from being a helpful tool for assessing construction delay causes’ impact, this developed user plug-in could also serve in future research works associated to this subject.

Systematic processing framework for analyzing the factors of construction projects’ delays in Egypt

Nowadays, the subject of delays is considered one of the most challenging problems for construction projects, particularly in Egypt. Delays occurrence normally leads to an increase in the project’s time and so its cost. Analyzing the factors of construction project delays in Egypt is a matter of crucial importance; thus, the reason why a systematic processing framework is developed. Considered as one of the main elements for this framework, a survey questionnaire was conducted among the key parties in the Egyptian construction industry. The aim is to assess the relevance and impact of the various delay causes on construction projects, to identify the responsible party as well as to evaluate the effect of using the Building Information Modeling (BIM) on delays. Thus, this paper promotes the use of a systematic processing framework to outline a course for examining delay factors of construction projects in Egypt while validating the outcomes through a survey questionnaire. This leads to prioritize delay causes and hence to identify the most suitable approach for dealing with construction projects’ delays and their associated cost impact. Also, it is worth mentioning that this framework is of major use to construction projects with similarity nature such as residential buildings, hotels, etc. This study opens the doors for further development of parametric models which will help in effectively treating this subject.

ANALYSIS OF CAUSES OF COST OVERRUN IN COMMERCIAL PROJECTS IN EGYPT.

Construction sector is developing every year due to use of new technologies and need of skilled labours to perform required designs. Hence, it is becoming more critical to ensure proper management of construction works to complete the project according to assigned objectives and specifications. The success of any construction work relies mainly on cost, time, and quality of work. Hence, proper management was done in order to ensure completion of projects according to expected and assigned budget. Nevertheless, projects in developing countries are yet suffering from potential overrun of cost due to multiple factors. There are multiple authors in literature that indicated the main problems faced by projects that prevents them from completing the project according to expected budget (Apolot et al, 2012), and (Memon et al, 2012). Hence, it became quite urgent to investigate reasons that lead to overrun of cost in construction works. Therefore, the major goal of this study is to investigate sources of cost overrun in construction projects in Egypt. The study will concentrate mainly on commercial projects due to the fact that most of these projects are extremely expensive and would require proper management to prevent any increase in its cost. The method of data collection is a questionnaire survey that included risk factors collected from previous literature. The expected outcome will be in the form of estimating reasons that lead to cost overrun, and impact of cost increase on performance of construction projects.

Advanced characterization of unbound granular materials for pavement structural design in Egypt

ABSTRACT Currently, Egypt is using the [AASHTO, 1993. Guide for design of pavement structures. Washington, DC: American Association of State Highway and Transportation Officials] guide for the flexible pavement structural design. In this method the resilient modulus (MR) of the unbound granular base/subbase materials and subgrade soils is a measure of material stiffness used for characterisation. It is considered one of the major factors affecting the pavement layerthicknesses. However, in Egypt, California Bearing Ratio (CBR) is the main strength parameter used for characterisation of the unbound materials and subgrade soils due to its availability and simplicity. In this research, a comprehensive experimental testing programme was conducted on different unbound granular base/subbase materials typically used in pavement construction projects in Egypt. The testing programme includes MR, CBR, and basic material properties. The effect of aggregate gradation on MR is investigated. A model predicting MR as a function of the basic material properties is proposed. The MR–CBR relationship adopted in the current Egyptian Code of Practice is verified based on the testing results. The experimental data warranted the calibration of the current model. The calibrated model has reasonable goodness of fit statistics and yields rational MR estimates for the local materials.

Assessment of transaction costs for construction projects

The main premise of transaction cost economics is that project cost is not only production costs but there are also additional costs resulting from transactions between parties. Transaction costs include the costs of preparing the bidding package, estimating and drawing up a contract, administering the contract, dealing with any deviations from contract conditions and any contractual problems include claims, change orders, and disputes. The main objectives of this paper are to establish the factors that affecting transaction costs in construction projects in Egypt, assessing its value in Egyptian construction projects, and to provide a mathematical model that can predict transaction costs value accurately. The study was conducted on various types of construction projects in Egypt, which formed the sample size. To collect data, a questionnaire was used that was personally administered to the respondents, using emails and conducting semi-structured interviews. The collected data were analyzed by using SPSS program, and a software package named IBM. The findings indicated that: the most important factors affecting positively (decreasing transaction cost value) on transaction cost value in construction projects in Egypt are: the financial position of the contractor, claims filed by the contractor, material substitutions by the contractor, contractor experience in similar type projects, contractor`s relationship with previous clients, contractor qualification to do the job, and procurement method.Transaction cost in the pre-contract phase of construction projects in Egypt is approximately (3–4) % of the contract value on average, and the average value for post-contract transaction cost is approximately (8–9) % of the contract value. All factors accredited as influential factors were taken into account and developed in an account model, the study devolved accounting models that can predict transaction cost value as a percentage of the project capital for construction projects in Egypt, two techniques were used, first is regression analysis with two methods (enter-stepwise), and second is the neural network, all models showed a high accuracy up to 95% in predicting transaction cost value for construction projects in Egypt.

Reducing CRR in fast-track projects through BIM

Rework is one of the most commonly encountered issues that face construction projects, leading to potential loss of money and delays. The aim of this study is to investigate the potential role of Building Information Modelling (BIM) in reducing Client-Related Rework (CRR) when set within the context of fast-track construction projects in Egypt. In order to study this issue survey data was collected from 51 construction professionals within the Egyptian private construction sector with experience in fast-track projects through a self-administered questionnaire composed of fourteen closed and open-ended subgroup of questions, whose aim is to gain an understanding of the main sources of CRR in the industry. The survey results revealed that the majority of the respondents (92.1%) had experienced CRR in construction projects, resulting in an average project cost increase of 22% and an average delay of 23%, as well as formulating the basis for a novel Severity Index (SI), which was devised in order to rank CRR causes, with its finding revealing "Clients' financial problems", "Impediment in prompting the decision making of the client" and "Replacement of materials by the client", as the biggest contributors to CRR. The survey also highlights visualization as a potential solution to CRR, with eight case studies from literature as well as one from the Egyptian market being used to validate the use of BIM in the reduction of CRR. Findings illustrated that the use of BIM in the Egypt is similar to findings in literature, with BIM resulting in rework cost and schedule reduction of 49 and 57 percent respectively.

Health and Safety Considerations in Mega Construction Projects

The construction industry is considered one of the most hazardous industries especially in Mega projects, not only in developing countries but also throughout the world due to its unique nature. The hazards of this industry make it very essential to pay more attention to construction safety and to improve the safety performance of construction companies. However, safety is not a luxury but a necessity, and may be considered an important function to be used against unnecessary loss. International Mega Construction projects are likely to become increasingly common in the engineering and construction industry. A Mega-project as a high impact technically complex project which requires careful advanced planning, large projects are defined as those with construction work valued in excess of US $1billion. On such projects, there may be 60 large contracting organizations and 30 to 40 consulting companies. The construction workforce could total 45,000 personnel delivering over 10 million man hours of effort per month at peak periods, so there is a need of guidance material that can be used to improve the management of health and safety(H&S) throughout these type of projects. Thus the aim of this paper is to identify the H&S considerations that are related to Mega Construction Projects. To achieve the aim of this paper a literature review analysis has been performed where more than hundred research paper that have been published from 1998, to 2018 have been analyzed. Findings of this paper have managed to identify the nature of mega construction projects, the root causes of accidents and the consequence of poor health and safety management in mega construction projects. This paper is considered of value to construction project officers and Project managers working in mega construction projects in Egypt and MENA region.

Identifying the Risk Impact on Cost and Time of the Egyptian Non-Residential Buildings Projects

Construction projects in Egypt were typically influenced by multiple risk factors which have various impacts on both cost and time objectives that lead to project cost overruns and time delays. This paper presents the results of an investigation study concerns with the identification and assessment of risks associated with the Egyptian Non-Residential Buildings Projects (ENRBP). The study explores risk factors probability of occurrence and their effects on cost and time of these projects. A field survey was conducted with professionals in the construction projects in EGYPT for a purpose of collecting the required data of the risk factors characteristics. Based on results analysis, several risk factors were identified and categorized into fifteen risk groups as well as they were prioritized based on their effects on cost and time. A high agreement for ranking risk factors among contractors, consultants and owners was acquired. The list of the major risks included many factors such as: dramatic changes in the materials prices and Adopting direct attribution system rather than tendering and bidding systems. The most expected average increase of the cost overruns and time delays was more than 20% of the project planned budget and schedule. Finally, the analysis and findings showed that risk factors were very close in their impacts on both cost and time of ENRBP.

Examining the role of value management in controlling cost overrun [application on residential construction projects in Egypt

Abstract Actual cost of construction projects generally differs from planned cost, where this could reach a value between 21% and 55%. In Residential construction, cost overruns form a crucial problem. A suggested methodology to mitigate this problem is Value Management (VM), which has proven to be an effective approach. Thus, the main objective of this paper is to examine the role of VM in Controlling Cost Overrun, with special reference to Residential Projects in Egypt. A literature review was applied on the basics of project cost implementation. In addition, a qualitative analysis of case studies was performed. Finally, a questionnaire survey that assessed the impact of applying VE on Residential projects in Egypt was performed. Findings of this paper highlighted the value added from applying Methodologies of VM, where it was observed that it could achieve 15–40% savings of the total project cost.

Risk assessment influencing factors for Arabian construction projects using analytic hierarchy process

Risk management is an approach of recognizing, classifying, analyzing and assessing of all risks in any project and is an important step for project success. Therefore, it is important to analyze and study parameters of construction risks. Numerous methods had developed to support project managers and contractors for risk management in construction. Applications of these methods enabled project managers to avert potential problems. “AHP” Analytic Hierarchy Process was discovered by Saaty (1980), and it had been studied with “MCDM” Multiple Criteria Decision Making; in this paper, AHP was used to normalize uncertainty estimates and rank risk likelihood occurrence which occurs specifically in construction projects in Egypt and Saudi Arabia during bidding and construction phases. The AHP enforcement steps had been simplified through “ECS” Expert Choice Software that is available for its fulfillment. A questionnaires survey was conducted to get opinion of experts for their priorities on most likely risks, which occur in Arabian projects, the answers were used to make pairwise comparison between all risks parameter, then AHP is applied to normalize uncertainty estimates and rank the risk likelihood occurrence. Results show project stakeholders believe that risk from financial as maximum likelihood occurrence of the construction projects. Design risk was the highest second rank most likelihood occurrence after financial risk. Political and construction risk was of the third rank.

Success Factors of Highway Construction Projects in Egypt: AHP Approach

While the idea of the existence of a set of key factors for success in planning, designing and construction of projects is not new, it remains one of the most important issues in the field of construction management. This is due to project success factors are inputs to project management practice which can lead directly or indirectly to project success. This study identifies the success factors which can be used for improving the highway projects performance in Egypt during the project pre-construction and construction phases. Through a detailed literature review 35 success factors are identified. Furthermore, the AHP is adopted to prioritize the studied factors through the application of questionnaire survey. The study establishes that implementing an effective quality control and assurance systems, allow sufficient time for feasibility studies, design, drawing and tender preparation, effective cost control system and frequency of project budget updates, preparing adequate designs and drawings and determining sufficient time to implement the desired scope of work are the most important success factors for enhancing the highway projects performance in Egypt.

Exploring delay causes of road construction projects in Egypt

Construction delays are a common phenomenon in civil engineering projects in Egypt including road construction projects. Therefore, it is essential to study and analyze causes of road construction delays. This paper studied a list of construction delay causes gathered from literature having different types of construction, different countries, different periods and different numbers of delay causes and delay groups. A questionnaire and personal interviews have formed the basis of this paper listing 293 delay causes. The questionnaire survey was distributed to 500 construction participants and 389 were received who represent consultants, contractors and site/design engineers excluding the owner representing the government in road projects as one party only. Relative Importance Index (RII) is calculated and according to the highest values the top twenty and the least twenty delay causes of construction projects in Egypt are determined. A case study is analyzed and compared to the most important delay causes in the paper. The test results reveal good correlation of causes and groups between contractors and site/design engineers and between consultants and site design engineers and a somewhat low correlation between contractors and consultants. So there are no root causes that can be taking for granted to be most or least effective delay causes. Proposed model for predicting actual road construction project duration was developed; a real case study tested the accuracy of proposed model. According to the analysis of case study, the most contributing causes and groups to delays were discussed, and some future recommendations were proposed in order to control and minimize delays in road construction projects. These findings can be helpful for project managers to mitigate the road construction delays in Egypt. In order to effectively overcome the road construction delays in developing countries, suggestions are made for fundamental and large‐scale reforms in procurement systems and stakeholders’ management. Also, this paper is useful for both researchers and road construction parties and allows detailed and repeatable analysis of the progress of a road construction project in order to facilitate and achieve a competitive level of time, cost and quality for effective road construction projects.

Development of a Safety Performance Index for Construction Projects in Egypt

The objective of this research paper is twofold. First, identify the main factors that can be considered as safety performance indicators for the construction projects in Egypt. The identification of these factors can contribute to creating awareness and/or improving safety performance. Second, develop a safety performance index for the Egyptian construction projects. Through a comprehensive literature review the different safety performance indicators were compiled. A questionnaire survey was conducted among construction experts to identify the relative importance of these indicators. The study collects data from 238 contractors. The collected data was included information regarding worker factors, environmental factors, and organizational factors. Finally, some statistical analyses were carried out to develop the proposed safety performance index. The study reveals the most important safety performance factors. Among these are the lack of historical factors, natural environment, incentives factors and project budget, plan, and safety training. Moreover, the developed index can be used as an effective tool to evaluate the expected safety performance of any construction project in Egypt.
