Analysis Of Uncontrolled Concrete Bridge Parapet Cracking, Jeffrey D. Bazzo Jan 2012

Analysis Of Uncontrolled Concrete Bridge Parapet Cracking, Jeffrey D. Bazzo

ETD Archive

The Ohio Transportation has recently identified the problem of wide-spread premature cracking of concrete bridge parapets throughout its District 12 region (Northeast Ohio). Many of the bridge decks that contain these prematurely cracked parapets are of relatively recent construction. In severe cases, replacement of the parapet may be required before replacement of the bridge deck itself. This incurs a sunk cost upon the bridge owner, as the parapets will again be replaced during the regularly scheduled replacement of the bridge deck. In a recent instance, the replacement of a cracked parapet (without replacing the deck) cost District 12 approximately $140,000. …

Construction And Demolition Debris Recovery And Recycling In Orange County, Fl, Michael Stephen Toth Ii

Electronic Theses and Dissertations

In 2008, the State of Florida established a recycling goal of 75% to be achieved by 2020. In response to the Florida goal Orange County (OC), Florida has made the development and implementation of an efficient strategy for landfill diversion of its solid waste a top priority. The Florida Department of Environmental Protection (FDEP) estimated that 23 % of municipal solid waste was generated by construction and demolition (C&D) activities in 2009, with only 30 percent of C&D debris being recycled. Therefore, OC decided to create a solid waste integrated resource plan (SWIRP) initially focused on the recovery and recycling …

A Framework For Process Data Collection, Analysis, And Visualization In Construction Projects, Reza Akhavian

Electronic Theses and Dissertations

Automated data collection, simulation and visualization can substantially enhance the process of designing, analysis, planning, and control of many engineering processes. In particular, managing processes that are dynamic in nature can significantly benefit from such techniques. Construction projects are good examples of such processes where a variety of equipment and resources constantly interact inside an evolving environment. Management of such settings requires a platform capable of providing decision-makers with updated information about the status of project entities and assisting site personnel making critical decisions under uncertainty. To this end, the current practice of using historical data or expert judgments as …

A literature search indicated that several previous research studies, including national surveys, addressing SHA joint practices have been conducted over the past 10 years. For up-to-date information, a new set of surveys were developed and distributed to all the SHAs by email through the AASHTO Subcommittee on Maintenance-Bridge Technical Working Group chairman in June 2010. There were …


Fate And Transport Of Escherichia Coli Within Sediment Basins On Active Construction Sites, Elizabeth Tempel May 2011

Fate And Transport Of Escherichia Coli Within Sediment Basins On Active Construction Sites, Elizabeth Tempel

All Theses

The conventional method of controlling sediment-laden runoff on construction sites is the use of sediment basins. These basins slow the velocity of runoff and allow the particles to settle from the water column before discharge to surface waters offsite. This best management practice, however, may create a reservoir for pathogenic bacteria. Sediment is known to provide protection for bacteria; therefore, while these basins decrease sediment loadings to water bodies downstream, they may introduce harmful levels of pathogenic bacteria into these surface waters. In addition to causing human health risks, these high bacteria levels alter natural biological makeup of downstream ecosystems. …

A Stochastic Hybrid Embodied Energy And Co2_Eq Intensity Analysis Of Building And Construction Processes In Ireland, Adolf Acquaye Oct 2010

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% …

Best Practices For Dealing With Price Volatility In Utah Commercial Construction, Justin Earl Weidman Jun 2010

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 …

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). …
