A Stochastic Hybrid Embodied Energy And Co2_Eq Intensity Analysis Of Building And Construction Processes In Ireland, Adolf Acquaye
A Stochastic Hybrid Embodied Energy And Co2_Eq Intensity Analysis Of Building And Construction Processes In Ireland, Adolf Acquaye
Doctoral
Given a general lack of research on Irish construction greenhouse gas emissions, a subsectoral embodied carbon dioxide equivalent (CO2-eq) analysis of this sector has been undertaken with the aim of overcoming some methodological challenges such as system boundary constraints, input-output aggregation, double counting of energy inputs and a general lack of data. Using this extended methodology, it is estimated that total embodied CO2-eq intensity of Irish construction in 2005 was 1,364gCO2-eq/€ with direct sub-sectoral embodied CO2-eq intensity averaging 56 gCO2-eq/€. Some 215gCO2-eq/€ is estimated to arise from domestic sources including 160gCO2-eq/€ from domestic indirect emissions. International arising emissions constituted 84% …

Construction Cost Models, Barry Dikeman
Economics and Finance
The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …
Best Practices For Dealing With Price Volatility In Utah Commercial Construction, Justin Earl Weidman
Best Practices For Dealing With Price Volatility In Utah Commercial Construction, Justin Earl Weidman
Theses and Dissertations
In the commercial construction industry, the problem of price volatility as it pertains to materials and labor is a consistent problem. The changing instability of market conditions presents a challenge for construction companies to accurately estimate and complete projects within budget. This volatility can lead to higher costs and more risk to suppliers, contractors, and owners which can cause financial distress for all parties involved in the construction process. As lump sum contracts are typically being used on many projects, the owners seem to have the upper hand and are forcing contractors to honor lump sum contracts even when prices …
Data Analysis Of Utah's I-80 And I-215 Bridges - For The Use In The Development Of Accelerated Bridge Construction Standards, Erik S. Rosvall
Data Analysis Of Utah's I-80 And I-215 Bridges - For The Use In The Development Of Accelerated Bridge Construction Standards, Erik S. Rosvall
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study discusses five bridges on Utah's I-80 that were replaced in the summer of 2008 using Accelerated Bridge Construction methods. Each superstructure was built offsite and moved into place with the use of Self-Propelled Modular Transporters. The bridges were instrumented and monitored during the moving process to investigate the effects of moving an entire superstructure into place. Collected data was analyzed to find the level of stress each superstructure experienced during lifting, moving, and placement of each bridge.
The change in supporting conditions from when the superstructure was built to being transferred onto Self-Propelled Modular Transporters caused significant stress …

Development Of A Cloud Solution For Smes In The Irish Construction Industry, Alan V. Hore, Alan Redmond, Roger West
Conference papers
There is a strong emerging trend within the Information Communication Technology (ICT) sector for replacing traditional packaged desktop applications with Web based, outsourced products and services. The drive for this innovative solution is its contribution to enabling software to be developed, delivered and consumed in discrete chunks (known as services) liberating the users from traditional computing and providing services accessible across a range of devices and appliances. The objective of this paper is to report on the progress towards defining this Web based service, commonly known as ‘Cloud computing’, for Small to Medium Size Enterprises (SMEs) in the Irish construction …
Building Support For Coud Computing In The Irish Construction Industry, Alan Redmond, Alan V. Hore, Roger West
Building Support For Coud Computing In The Irish Construction Industry, Alan Redmond, Alan V. Hore, Roger West
Conference papers
The construction industry has been traditionally recognised as a fragmented sector associated with a poor level of implementation and penetration of Information Communication Technology (ICT) by Small to Medium Size Enterprises (SMEs). Cloud computing is a collective term that can facilitate the ability to collaborate within a central repository that can act as a base for interoperability between various construction disciplines and their software applications. Cloud computing is a new layer of internet architecture that creates an open opportunity to add better functionality to an increasingly global network. The characteristics of cloud computing, such as, shared infrastructure, on-demand applications, elasticity …

Change Orders And Lessons Learned, Paul Goodrum, Timothy R. B. Taylor, William Lester, Alex Mccoy, Mohammed M. Uddin, Yongwei Shan
Kentucky Transportation Center Research Report
Many times, change is necessary for the success of a project. “Change, defined as any event that results in a modification of the original scope, execution time, or cost of work, happens on most projects due to the uniqueness of each project and the limited resources of time and money available for planning” (Hanna, Camlic, Peterson,& Nordheim, 2002). While change orders are necessary to address unforeseen conditions and other unavoidable or unanticipated occurrences, they tend to negatively affect construction. In most public works, change orders are the main reason for construction delays and cost overruns (Wu, Hsieh, & Cheng, 2005). …

The Relationship Between Information Technology And Construction Productivity, Dong Zhai
University of Kentucky Doctoral Dissertations
Over the past decades, information technology has been impacting industries, economics, the way of life and even the culture throughout the world. Productivity has been attracting much attention as an important indicator of economics, and numerous researchers have investigated the relationship between information technology and productivity. Construction is one of the largest industries in the United States, but little research has been conducted to investigate the relationship between information technology and construction productivity.
The major objective of this dissertation is to determine the degree (if any) to which information technology usage, specifically the use of information technology to automate and …

Finding A Middleware Ict Solution For The Irish Construction Sme Sector, Alan V. Hore, Alan Redmond, Roger West
Conference papers
A key feature of the Irish construction industry is its fragmented structure. Some 16,000 businesses list their main activity as construction, yet no company has more than 3% of the total Irish output. The top 20 companies have less than 15% of total output. There is a very high number of Small to Medium Sized Enterprises (SME‟s) in the sector. However, most software products which address the specific needs of the construction industry are designed for larger companies. It is felt that the needs of the large number of SME‟s in the sector are underserved. The Construction IT Alliance (CITA) …
