Predicting The Indirect Cost Of Construction Projects In Egypt: An Artificial Neural Network Approach, Aya Effat

Theses and Dissertations

Cost estimation is one of the vital processes in construction management that needs to be done early in any project in order to determine the project's budget. The accuracy of the cost estimate is a key factor in the success of construction projects since it enables project managers to successfully control the project’s expenses. Construction costs mainly consist of direct cost and indirect cost. Generally, indirect costs can be categorized into two types: site overheads and general overheads. In a construction project, overheads, particularly site overhead costs, make up a considerable portion of a contractor's budget. Accordingly, accurately estimating the …

A Socio-Ecological, Multi-Stakeholder Investigation Of Apprenticeship Training Engagement In The Irish Construction Industry, Eoghan Ó Murchadha

Doctoral

The construction industry in Ireland is crucial to the national economy, not just in terms of economic output, but as a major provider of employment. The construction labour market is a complex concatenation of professions relying upon adequate skills supply. Apprenticeships play a critical role in future skills provision and are thus vital to the successful implementation of strategic government targets such as the National Development Plan 2021-2030. However, the extant employer-led model of skills engagement is prone to labour market failure given the cyclical elasticity of the industry. Nonetheless, there is a paucity of research into apprenticeship engagement …

Weather-Related Construction Delays In A Changing Climate: A Systematic State-Of-The-Art Review, Steven J. Schuldt, Matthew R. Nicholson, Yaquarri A. Adams Ii, Justin D. Delorit

Faculty Publications

Adverse weather delays forty-five percent of construction projects worldwide, costing project owners and contractors billions of dollars in additional expenses and lost revenue each year. Additionally, changes in climate are expected to increase the frequency and intensity of weather conditions that cause these construction delays. Researchers have investigated the effect of weather on several aspects of construction. Still, no previous study comprehensively (1) identifies and quantifies the risks weather imposes on construction projects, (2) categorizes modeling and simulation approaches developed, and (3) summarizes mitigation strategies and adaptation techniques to provide best management practices for the construction industry.

Supply Chain Management: Fragmented Adoption In Practice, Tayler J. Yoshimura

Construction Management

Every day the construction industry develops new ideas and theories toward innovation in increased efficiency and quality for its projects. One method is supply chain management, which focuses on the relationships between partnerships along the supply chain. The theory was first developed in the manufacturing industry and this paper will highlight the reasons behind its fragmented adoption in the construction industry. The overall supply chain typically contains short supply chains that are dismissed upon project completion. Some companies have partially adopted the theory into their work practices but has been unable to fully adopt the theory as a whole. There …

Sustainable And Resilient Construction: Current Status And Future Challenges, Niamh Murtagh, Lloyd Scott, Jingli Fan

Articles

The construction industry globally is one of the most environmentally damaging of sectors. Additionally, the resources consumed and the operational energy requirements of buildings are ‘locked-in’, potentially for decades. The Intergovernmental Panel on Climate Change has recognised construction as a sector in which significant improvements can, and indeed must, be made. But the industry is often argued to be unique, in its multiplicity of stakeholders, transient organisational structures, avoidance of risk and impact on society. The current Virtual Special Issue (VSI) sought to bring together a collection of papers on progress and potential for improvement in the construction sector, in …

Quantity Surveying Professional Apprenticeships: A Paragon For The Supply Of Talent In The Irish Construction Industry, Eoghan Ó Murchadha, Roisin Murphy

Conference papers

The construction industry in Ireland has undergone considerable change in the last decade, the effect of which has resulted in a legacy malfunction in the construction labour market. The recent construction downturn led to high levels of construction unemployment, resulting in the mass emigration of construction professionals. Additionally, perceptions of job uncertainty in construction deterred new entrants into construction-related training and education programmes such as Quantity Surveying. If a skills gap is allowed to prevail, then there is a tangible threat to the industry’s cost competitiveness. As such, value for money becomes merely theoretical, and the cost to the economy …

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 …

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. …

Beyond Sustainability: The Contractor’S Role In Regenerative System Design, Rebecca Mirsky, Anthony Songer

Rebecca Mirsky

Current business models employ the concept of the triple bottom line to integrate three aspects of sustainability into the organizational process: economic growth, environmental protection and social equity. This concept is evolving toward a regenerative design approach that promotes a triple "top" line, moving accountability to the beginning of the design process by assigning value to a variety of economic, environmental and social factors. There is an increasingly important need for proactive participation from the construction community in this new generation of sustainability efforts. Otherwise, there will be a widening gap between design and construction, in which the contractor role …
