Overcoming The Limitations Of The Green Pyramid Rating System In The Egyptian Construction Industry: A Critical Analysis, Ahmed Osama Daoud, Ayman Ahmed Ezzat Othman, Obas John Ebohon, Ali Bayyati

Architectural Engineering

Despite the tangible contributions of the construction industry to social development and economic growth, it is known for its natural resources overconsumption and solid waste (SW) generation both of which have major negative impacts on the natural environment. In the particular case of materials waste, the construction industry worldwide accounts for about 50% of global annual generated SW. In addition, construction materials may contribute up to 50% of the total project cost. Accordingly, the negative implications of the construction industry have compelled many nations to develop green building rating systems in order to preserve the environment, promote the economic efficiency …

Achieving Sustainability Through Reducing Risks During Architecture Design Process: A Lean Management Perspective, Sherouk Abdelrehim, Ayman Ahmed Ezzat Othman

Architectural Engineering

The construction industry, as one of the largest industries in the world, plays a critical role in achieving national and international social and economic sustainable development goals. Socially, it is concerned with delivering long-term projects that turn client and end-user requirements into designs that specify technical aspects, functional specific requirements, and standards of quality. Economically, the construction industry contributes to a country's gross domestic product (GDP) by creating jobs and providing the country's infrastructure. the construction industry's nature is more vulnerable than other industries. This is believed to be due to the complex and dynamic nature of construction projects, as …

Causes Influencing Construction Waste Generation During The Design Process: An Analytical Study, Aya Saad, Ayman Ahmed Ezzat Othman

Architectural Engineering

Despite the social and economic contributions of the construction industry towards achieving sustainable development objectives, it has an adverse effect on the environment such as the generation of waste, water, and energy consumption. Construction waste (CW) is the loss of materials that are produced during or after the construction process and has no remaining value. Several countries promote waste elimination plans at early stages to reduce CW at its source. The Egyptian government is expanding its investments in new mega projects and infrastructure facilities like new administrative capital, bridges, roads, energy projects which resulted in increasing the rate and amount …

Quantifying Materials Waste In The Egyptian Construction Industry: A Critical Analysis Of Rates And Factors, Ayman Ahmed Ezzat Othman, Ahmed Osama Daoud Dr., Obas John Ebohon, Ali Bayyati

Architectural Engineering

Construction and demolition waste (CDW) is a critical challenge facing the construction industry. It leads to deterioration of the triple bottom line of sustainability. Unfortunately, the CDW management research in Egypt lacks studies investigating (1) the variations in CDW generation (CDWG) among different types of construction projects, and (2) the factors affecting CDW reduction (CDWR). Based on a benchmarking approach, this research (1) quantifies CDW in terms of generation rates and costs among different construction project types in Egypt, and (2) investigates the relationship between CDWG and different adopted CDWR factors. Using structured interviews, a comparative case study was conducted …

A Framework For Achieving Sustainability By Overcoming The Challenges Of The Construction Supply Chain During The Design Process, Ayman Ahmed Ezzat Othman, Nooran Alnassar

Architectural Engineering

This paper aims to develop a framework to achieve sustainability by overcoming the challenges of the construction supply chain (CCSC) during the design process. To achieve this, two approaches, namely theoretical and practical, were used to accomplish four objectives. For the theoretical approach, based on literature review and case studies, the objective used was to identify, classify and validate the challenges that the construction supply chain (CSC) encounter. For the practical approach, a survey questionnaire was employed to quantify the CCSC and investigate the perception of architectural design firms (ADFs) in Egypt towards achieving sustainability by overcoming the CCSC during …

Achieving Sustainability Through Reducing Construction Waste During The Design Process: A Value Management Perspective, Ayman Ahmed Ezzat Othman, Sherouk Mohamed Abdelrahim

Architectural Engineering

Purpose:

The purpose of this paper is to investigate the role of Value Management towards achieving sustainability through reducing the construction waste during the design process.

Design/methodology/approach

To achieve the abovementioned aim, a research methodology consisting literature review and survey questionnaire is designed to achieve the following objectives: first, building a comprehensive understanding of the research topic through reviewing literature related to the nature of the construction industry, waste in construction, sustainability, the design phase and Value Management; second, presenting and analysing two case studies to validate the role of Value Management towards reducing waste in construction projects; third, conducting …

An Investigation Into Solid Waste Problem In The Egyptian Construction Industry: A Mini-Review, Ahmed Osama Daoud, Ayman Ahmed Ezzat Othman, Herbert Robinson, Ali Bayyati

Architectural Engineering

Solid waste management (SWM) is one of the most critical global challenges nowadays. It has a severe negative effect on the triple bottom line of sustainability. Construction and demolition waste (CDW) contributes about 50% of the total global annual generated SW. In the particular case of the Middle East and North Africa (MENA) region including Egypt, the SW problem has become a major challenge, and the need to find sustainable solutions is overwhelming. However, the region faces several challenges that hinder the development of an effective and efficient SWM system. This has resulted in the predominance of unsustainable SWM practices …

A Framework To Activate The Health And Safety Regulations In The Egyptian Construction Industry, Mostafa Adel Elsebaei, Ayman Ahmed Ezzat Othman, Omar Elnawawy, Mohammed Badawy

Architectural Engineering

Purpose

The construction industry is considered one of the most dangerous industries especially in developing countries such as Egypt. Although safety in Egypt is regulated by mainly four pivotal legislations, namely, Law No. 12 (2003) and Ministerial Decrees No. 211, 126 and 134, construction accident records in Egypt are high. Accordingly, this paper aims to develop a framework to activate the health and safety regulations in the Egyptian construction industry.

Design/methodology/approach

To achieve this aim, a research methodology consisting of a literature review and a survey questionnaire was developed to accomplish three objectives. First, a literature review was used to …

A Framework For Implementing Integrated Project Delivery In Architecture Design Firms In Egypt, Ayman Ahmed Ezzat Othman, Lamis Yasser Wagih Youssef

Architectural Engineering

Purpose

This paper aims to develop a framework for implementing the integrated project delivery (IPD) approach during the design process in architecture design firms (ADFs) in Egypt.

Design/methodology/approach

A research methodology consists of literature review, case studies and survey questionnaire was designed to achieve the abovementioned aim. First, literature review was used to identify and categorise the challenges of implementing IPD during the design process. Second, four case studies were analysed to investigate the values delivered to the client or missed due to the use of IPD or traditional procurement approaches, respectively. Finally, a survey questionnaire was carried out with …

Elements Of Safety Management System In The Construction Industry And Measuring Safety Performance – A Brief, Mostafa Elsebaei, Omar Elnawawy, Ayman Ahmed Ezzat Othman, Mohamed Badawy

Architectural Engineering

Construction industry is considered to be one of the most hazardous industries in the world. The reason could be attributed to its hazardous nature as it is an accident-prone industry. Thus, a need for better understanding of safety management system is essential for improving safety performance in this sector. This paper discusses briefly the elements of safety management by presenting different systems (such as Oregon OSHA Occupational Health and Safety Administration, and OTAR Overseas Territories Aviation Circle) and elaborating their elements. It also discusses two types of measuring safety performance the first is the lagging indicators and the second is …
