Commercial Construction Schedule Collaborators And Current Scheduling Practices, Evan D. Bingham, Jay P. Christofferson, Mark Hutchings

The Professional Constructor

Construction mangers use the project schedule to communicate aspects of construction timing critical to project success. These schedules may be created using the collaboration of multiple project stakeholders or be the creation of a single manager. The tools used to create and communicate the schedule could range from hand drawn to critical path computer software. Because these practices may vary from company to company, commercial construction mangers can benefit from an understanding of common scheduling practices in the industry. This paper is a report of findings for commercial contractors working in the western United States. Construction managers working for 23 …

Attraction And Retention Of Minority Managerial Employees At Electrical Contractors, Ben F. Bigelow, Anthony J. Perrenoud, Anusree Saseendran

The Professional Constructor

Diversity in the managerial workforce in construction is limited, with a shortage of talent in the industry and the demand projected to grow over the next ten years. The challenge of attracting and retaining managerial talent is exacerbated for trade contractors as they have historically promoted management from the trades. This study explored differences, based on ethnicity, when it comes to factors that attract and retain managerial talent in electrical construction. Data was collected through a nationwide survey of management employees of electrical contractors. It was found that while some factors were influential for all ethnic groups, certain factors became …

Building Information Model-Based Quantity Takeoff – Leadership Support And Training, Morgan Tagg, James P. Smith, Jay P. Christofferson, Kevin R. Miller

The Professional Constructor

Building Information Modeling (BIM) plays an important role in the modern construction industry. BIM models are tools that help stakeholders perform a variety of functions including communication, visualization, trade coordination, and clash detection. A less commonly utilized functionality of BIM that shows strong potential to improve efficiencies and reduce error is model-based quantity take off (QTO). The literature identifies eight challenges to implementing BIM QTO. This paper focuses on the leadership and training elements inherent to two of the identified challenges – 1) New skills and training, and 2) reluctance of employees to adopt. Through semi-structured interviews with estimators, preconstruction …

Effects Of Organizational Trust And Project Delivery Variables On Bim User Confidence, Jason D. Lucas, Saw Sri Neeharika Vijayarao

The Professional Constructor

The use of Building Information Models (BIM) for construction planning has increased in all areas except for automated processes such as quantity take-off. Many model users lack confidence that a model, typically created by a third party, has accurate enough information in it to rely on the data for planning the project. This research is looking at how factors of organization trust and variables related to project delivery can raise user confidence in these situations. Factors of organizational trust were identified through a literature review. Two surveys were utilized to identify which factors were significant in raising user confidence. Finally, …

Accuracy Of Drone Based Surveys To Measure Stockpile Volume, Joseph M. Burgett, Scott Shaffer, Eric Stuckey

The Professional Constructor

This paper outlines a two phase experiment evaluating the accuracy of volumetric calculations using a commercially available drone and structure-from-motion (SfM) software. In the first phase, a large cardboard pyramid with a known volume was used to simulate a stockpile. Using georeferenced images collected by a Phantom 4 Pro drone and the SfM software ContextCapture, the computed volumes ranged between 1.5% and 3.3% of the actual volume. In the second phase of the experiment, a photometric survey was created of a large SCDOT borrow pit. The volumetric calculations were computed using conventional survey practices and with drone collected images. There …

Annual And Seasonal Variation In Hydrologic Performance Of Ecoroofs Of Multiple Depths, Portland, Or, Ashley Michelle Baker

Dissertations and Theses

It is essential that cities adopt new approaches to stormwater management in the face of changing precipitation regime. In some locations, ecoroofs have been incorporated into city plans as a stormwater control measure, and thus their real-world performance under current conditions can assist with adequate planning. In this study rainfall retention data collected during a three year period, between 2014-2017, is analyzed for 75mm and 125mm ecoroof plots in Portland, Oregon, USA. There is no difference in annual rainfall retention performance between the shallower and deeper plots. However, the 36% mean annual retention of the ecoroof plots is a significant …

Interlocking Rocking Clt Shear Walls With Viscous Dampers, Sydney Gallion, Abby M. Lentz, John Lawson

Architectural Engineering

While the use of cross laminated timber (CLT) has become more common, the implementation of CLT as shear walls remains rare because there is no universally recognized response modification coefficient, R, currently adopted for base shear. In addition, CLT shear walls are relatively stiff as a seismic force resisting system and inelastic behavior of the system is often relegated to vulnerable connections. There is also an inherent issue with instability due to overturning in multi-story buildings due to transportation limitations on the size of CLT panels. Past research by others has successfully utilized post-tensioning to create self-centering rocking CLT …

Feasibility Of A Fiber Reinforced Polymer Retrofit For Non-Ductile Concrete Walls, Rory S. De Sevilla, Jerry Hue Truong Luong, Anahid A. Behrouzi, Peter T. Laursen, Mike J. Deigert

Architectural Engineering

A significant number of pre-1980’s non-ductile reinforced concrete (RC) structures in California have been identified as deficient, many of which utilize RC shear wall systems to resist earthquake lateral forces. These non-ductile wall systems are typically lightly reinforced and lack adequate boundary element detailing. Engineers suspect these walls to susceptible to brittle, compression-controlled failure modes due to damage from concrete crushing and bar buckling. As a result, one approach designers are taking is to seek fiber reinforced polymer (FRP) retrofit solutions that improve the compression capacity of high-stressed wall end zone regions based on effectiveness of these approaches with columns. …

Improving The Accuracy Of Wood Diaphragm Deflection Computations And Its Impact On Asce 41 Pseudo-Lateral Force Estimates, John Lawson

Architectural Engineering

Structures with flexible seismic resisting systems tend to develop less seismic forces than their stiffer counterparts. While it has been commonly known that taller buildings in general have longer periods that result in a reduced spectral response, the analysis of one-story buildings with large, wide horizontal flexible diaphragms supported by stiff shear walls are now recognized as having a similar response. This building type often referred to as rigid wall – flexible diaphragm (RWFD) is very common in warehousing and big-box retail occupancies. Estimating the diaphragm deflection has become more important recently, not only because diaphragm deflections are more frequently …

Leap Of Faith Megaprojects: The Effect Of Civic Dialogue On Megaproject Legacies In The St. Louis Region, Nathan Theus

Theses

Megaprojects are unique capital improvements that are defined by their large-scale development plans and construction budgets. Industrial Belt cities, like St. Louis, are no stranger to these projects, and both government actors and private developers have walked hand in hand in planning and constructing megaprojects, while assuring the general public that the benefits would always outweigh the costs. Though there has been considerable quantitative research analyzing the statistical economic effects of various megaprojects, there has been relatively little discussion on other, specifically, qualitative means of analysis. This paper will examine the role civic dialogue has on the perceived and real …

Digitally-Mediated Practices Of Geospatial Archaeological Data: Transformation, Integration, & Interpretation, Heather Richards-Rissetto, Kristin Landau

Department of Anthropology: Faculty Publications

Digitally-mediated practices of archaeological data require reflexive thinking about where archaeology stands as a discipline in regard to the ‘digital,’ and where we want to go. To move toward this goal, we advocate a historical approach that emphasizes contextual source-side criticism and data intimacy—scrutinizing maps and 3D data as we do artifacts by analyzing position, form, material and context of analog and digital sources. Applying this approach, we reflect on what we have learned from processes of digitally-mediated data. We ask: What can we learn as we convert analog data to digital data? And, how does digital data transformation impact …

The Effect Of Season On Construction Accidents In Saudi Arabia, Abdurahman Ammar

Emirates Journal for Engineering Research

Construction workers are exposed to extreme conditions over a large portion of the work day during the different seasons of the year when working on construction sites. Some studies have discussed the effect of seasonal timing of work-related injuries and concluded that more injuries occur during the summer months [1]. Other studies concluded that accidents are more likely to occur during rainy seasons [2]. Construction accidents data from 2004 to 2011 were obtained from the General Organization for Social Insurance (GOSI). A two way ANOVA analysis showed that there was no significant difference among the years in terms of number …

At the time of this study, 11.4% of Nebraska’s …

Centerville City Parks Master Plan, Paul Stead

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This Plan B Thesis is a comprehensive update to Centerville City’s Parks Master Plan. The document seeks to provide stability and continuity to Centerville’s open space infrastructure. Since the last update in 1993, the Parks Master Plan has been without regular updates to reflect the community’s needs and values. As a result, the Plan has largely been ignored and Centerville has lacked a unified vision regarding parks planning. The objective of this thesis project is to help promote a unique recreational identity that assists the community in positively differentiating itself from other communities on the Wasatch Front.

Jane’S Urban Ethics: Jane Jacobs On Racism, Capital, Power, And The Plantation Mentality Peter L. Laurence, Peter L. Laurence

Publications

The 2016 centennial of Jane Jacobs's birth was an opportunity for scholars and pundits to reflect on the legacy of The Death and Life of Great American Cities and the author's other works and activism. Such reflections naturally reflected on her enduring appeal and readership, but also sought to find shortcomings. Among the critics, and even some otherwise admiring biographers, was a theme that while Jacobs was keen to observe the importance of “eyes on the street” and other street-scaled phenomena, she was weak on such overarching structural concerns as racism, power, and capital. From such charges arose claims that …
