Understanding Time, Cost, Quality, And Risk Trade-Off In Construction Projects Through A Review Of Literature & Survey Distribution, Aalaa Mohammed

Publications and Research

In the construction industry, projects consist of many different variables that affect successful completion. These variables may be scope, cost, time, quality, risk management and assessment, and more. Although all factors affect various construction projects differently, the three main variables that often result in a need for a trade-off decision are cost, quality, and time. Often referred to as the “Iron Triangle” or the “Triple Constraint”, many times owners and project managers are put under the pressure of having to choose two out of the three variables. If the project is cheap, it cannot be completed quickly and be of …

Analysing Bim Implementation In The Egyptian Construction Industry, Ayman Ahmed Ezzat Othman, Mohamed Marzouk, Heba Elsaay

Architectural Engineering

Purpose – This research is built up upon exploring the concepts of building information modeling (BIM) adoption and strategy formulation with the aim to develop a strategy for implementing BIM in the Egyptian construction industry. Design/methodology/approach – The development of the BIM implementation strategy was based on two pillars, namely the literature review and results of the survey questionnaire and interviews. First, the review of literature helped investigating the BIM challenges and international strategies developed to implement BIM worldwide. Findings – The research presented recommendations to assist policymakers in Egypt to facilitate BIM implementation. Originality/value – Although multiple frameworks have …

Social Sustainability Indicators In Mass Housing Construction, Ali Karji, Asregedew Woldesenbet, Mostafa Khanzadi

Durham School of Architectural Engineering and Construction: Faculty Publications

In the construction industry, buildings constitute more than half of the new construction built in the world. With the rapid growth of population in urban areas and high-energy consumption of buildings, considerable attention and efforts have been devoted to creating a sustainably built environment. As a result, various sustainable rating systems, principles and tools have been developed in recent years. This paper presents efforts underway for evaluation of sustainability in mass housing construction projects in the Middle East from a social aspect. The study reviews reports, guidelines and best practices at national and international levels to detect key sustainability indicators. …

The Impact Of Project Delivery Methods On Dispute Occurrence In Public Highway Projects, Samaneh Nasrollahi, Ghada M. Gad, Alan Atalah

Master of Technology Management Plan II Graduate Projects

The construction industry is a complex and competitive industry in which different participants with different expertise, talents, and levels of knowledge work together to achieve their objectives and complete a project. Sine different participants with different interest involve in a construction project, therefore, conflicts arise and become inevitable. Conflicts in projects will cause an adversarial environment which result to disputes. Hence, if conflicts are not well managed and resolved in a timely manner, they quickly turn into disputes, which prevent the successful completion of the construction project, in terms of cost and time, and increasing the potential for poor project …

Measuring Construction: Prices, Output And Productivity, Rick Best, Jim Meikle

Rick Best

Despite the size, complexity and importance of the construction industry, there has been little study to date which focuses on the challenge of drawing reliable conclusions from the available data. The accuracy of industry reports has an impact on government policy, the direction and outcomes of research and the practices of construction firms, so confusion in this area can have far reaching consequences. In response to this, Measuring Construction looks at fundamental economic theories and concepts with respect to the construction industry, and explains the merits and shortcomings, sometimes by looking at real life examples.

Performance Measures For Construction, Craig Langston

Craig Langston

Extract: The global construction industry is highly competitive, fragmented and cyclical and frequently operates on low margins (Loosemore 2003). Yet construction accounts for a significant portion of economic activity and is a catalyst for many other sectors. The industry is also labour intensive and project specific and involves team relationships that form and disband on a regular basis. It is not surprising, therefore, that construction performance and reform have dominated research within the industry for more than 50 years.

Implementation Of Integrated Project Delivery On Department Of Navy Military Construction Projects, Christopher S. Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

The concept of the project delivery system refers to the overall processes by which a project is designed, constructed, and/or maintained. There are many different types of project delivery systems to fit particular situations involving the owner and his intended project. The project delivery system is what establishes the framework that enables a construction project to be developed and ultimately executed.

The construction industry has observed that projects (both private and public) frequently suffer from factors such as adversarial relationships, low roductivity, high inefficiency and rework, frequent contractual disputes concerning who was at fault, and lack of innovation. Not only …

A Fuzzy Approach For Assessing Contractors Competitiveness, Yongtao Tan, Li-Yen Shen, Craig Langston

Craig Langston

Purpose – Proper assessment of contractors' competitiveness is important for assisting contractors in taking internal analysis and for assisting clients in selecting suitable contractors. This paper seeks to address this issue.

Design/methodology/approach – With previously identified contractor key competitiveness indicators (KCIs), this study presents a fuzzy competitiveness rating (FCR) method for measuring contractor competitiveness with reference to the Hong Kong construction industry. A set of linguistic terms is used for facilitating the assessment process.

Findings – For illustration, an example is used to show the application of the FCR method. The results provide valuable information for helping contractors in the …

Material And Energy Flow Analysis Of The Irish Construction Sector, Rachel Woodward

Theses

A national flow model for concrete was developed using the framework of material and energy flow analysis. Using this framework, the Irish concrete material and energy cycles for the year 2007 were constructed by firstly analysing the material life cycle of concrete which consists of the three phases of production (including extraction of raw materials and manufacture of cement), usage into stock (ready-mix and other concrete products), and waste management. In this year, approximately 35Mt of raw materials were extracted to produce both 5Mt of cement and 33Mt of concrete, with 4.5Mt of cement going into the production of concrete. …

The Development And Testing Of A Purchasing Power Parity Method For Comparing Construction Costs Internationally, Rick Best

Rick Best

Over the past fifty to sixty years there have been numerous attempts to compare the performance of the construction industries of different countries. In almost all cases the cost of construction has been an important, sometimes the single parameter Cost performance has sometimes been equated to productivity, and productivity measurement and comparison is attempted by governments and their agencies on a regular basis.

Fundamental to these exercises has been the necessity to bring construction costs in different national currencies to a common base. This is imperative as amounts in different currencies cannot be directly compared.

A Model To Distribute Mark-Up Amongst Quotation Component Items: An Outline, David Cattell, Paul A. Bowen, Ammar P. Kaka

David Cattell

The outline of a proposed new unbalanced bidding model is discussed. Background is provided as regards the role of item price loading, otherwise known as unbalanced bidding. Three types of loading are described, namely those of ‘front-end loading’, ‘back-end loading’ and ‘quantity error exploitation’ (otherwise known as ‘individual rate loading’). It is proposed that one single mathematical model could embrace all three of the above types and that the aspect of risk may be addressed partially by means of using the quadratic programming techniques employed within the field of Modern Portfolio Theory. MPT is a field pioneered by Markowitz in …
