Best Practices For Reducing Construction Accidents Involving Hispanic Construction Workers, Michael E. Asuquo, Khalid Siddiqi

The Professional Constructor

The objective of this study was to determine best practices for reducing accidents among Hispanic construction workers. It was hypothesized that language barrier between the Hispanics and American workers contributed immensely to high rate of construction accidents on industrial projects. Accident case studies and questionnaire survey were both used. Data was collected through semi-structured interviews with Hispanic workers involved in industrial construction projects in Metro Atlanta. Findings from the study concluded that most accidents involving Hispanic workers were caused due to lack of communication from supervisors, ignorance of workers on work procedures, lack of equipment training, and worker negligence. Language …

Construction Management Internship: A Key Opportunity For Assessment And Continuous Curriculum Improvement, James S. Vaux, Bree Dority, Dana E. Vaux

The Professional Constructor

The internship is an integral part of most Construction Management curricula. Studies have noted the importance and reciprocal value of internships for the student, the employer, and the academic program. However, to date, no studies have specifically outlined the value internships provide to the CM program for assessment and evaluation. This paper examines the value of the CM internship as an indirect measure to assess and incorporate change into program curricula. With 10 years of qualitative and quantitative data collected from CM student interns, industry employers, and university internship supervisors, this study supports that CM internships are a valuable tool …

Critical Evaluation Of Time And Cost Of Terrestrial Laser Scanning For Construction Automated Qa Analysis, Joao Rocha, Davitt Lamon

Capstone Reports

Many governments agencies and private owners are demanding up-to-date information related to the current conditions of their facilities. Conventional QA is time-consuming and inefficient; thus, 3D terrestrial laser scanning (TLS) technology has been adopted due to the fast speed and high accuracy in acquiring data. Automated QA analysis can reduce the labour and time needed, reduce the costs, and improve the overall project efficiency. However, very few research efforts have been made to study the benefits of the automated QA analysis in a quantitative way. The process of the TLS-based geometric QA based in an automated data analysis process is …

Residents’ Satisfaction With Apartment Living In Kuwait: A Study Of The Design Of Jaber Al Ahmad Apartments, Fawzi Alzamil, Qutaiba E. Al-Shaheen

Emirates Journal for Engineering Research

This study examines public housing in Kuwait and Jaber Al Ahmad apartments housing project. It tries to figure out how housing provision, citizen expectations, and satisfaction are linked.

Kuwait's government provide housing for Kuwaiti married couples as part of a welfare program. This goal has proven difficult to achieve, with a waiting list of over 100,000 people. While the majority of applicants apply for a residential plot and a housing loan to build a single-family home, a small number of candidates apply for the apartment unit’s alternative.

The government's capacity to reduce housing demand hinges on its ability to persuade …

Corrosion Performance Of Embedded Steel Bar In Cl--Contaminated Limestone Calcined Clay Cement (Lc3) At Initial Stage Of Hydration, Weiwen Li, Zuhua Xu, Yaocheng Wang, Xin Wang, Feng Xing

International Conference on Durability of Concrete Structures

Limestone Calcined Clay Cement (LC3) presents brilliant properties in binding Cl^- so that the embedded steel bars are probably protected in Cl^--contaminated condition, which meets the need of sea sand application. However, the corrosion performance of steel bars embedded in LC3 paste with Cl^‑ is unclear, especially in early age hydration. Thus, a series of experiments were carried out to evaluate the corrosion performance of steel bars on initial and hardened stages of hydration, including concentration of OH^- and Cl^- in real pore solution, open circuit potential (OCP) and chemical elements of steel bars. …

The Effect Of Initial Water Saturation On Freeze-Thaw Damage Of Submerged Mortar Materials, Siyuan Chen, Huigang Xiao

International Conference on Durability of Concrete Structures

An indispensable condition for the occurrence of the freeze-thaw (F-T) damage in unsaturated cement-based materials is that the specimens absorb water during the F-T process and reach a critical level of water saturation, which is influenced by the initial degree of water saturation (IDWS). However, the fast-freeze method commonly used in the laboratory does not reflect the effect of the IDWS on F-T damage. Thus, this study investigated the effect of different IDWS on the development of F-T damage in specimens to fill the gap in this research area. In this study, compressive strength tests were used to characterize the …

Alternative Redistribution Of Residential Solar Energy, David T. Holmes

Construction Management

The use of solar panels on residential structures has been prevalent since the mid 1970’s and over the decades their presence has become more pronounced and more valued. The creation of energy on-site using clean methods for an individual is truly a remarkable feat. As solar panels become increasingly common, so do the inherent issues and their supporting infrastructure. Of these issues a common inconvenience is what owners are to do with extraneous energy. What this entails is that an owner typically does not have means to store energy that is created in surplus, the resulting solution is the power …

A Review Of Current Construction Guidelines To Inform The Design Of Rammed Earth Houses In Seismically Active Zones, David Thompson, Charles Augarde, Juan Pablo Osorio

Articles

Sustainability in the materials we use for construction is a prime concern, focusing on reducing the embodied energy and carbon footprints of the materials used. The cement used in concrete products is responsible for a significant proportion of Man's CO2 emissions and its production requires substantial energy input, as do fired clay products. For this reason, products formed from unfired earthen materials are of increasing interest and the current challenges include devising means of robust design for strength and to address durability concerns. One form of earthen construction that employs an in-situ method is rammed earth, and it is a …

Plastic Bottles In Architecture: A How To Guide On Life-Cycle Through Reuse, Crystallyne Landram

Architecture Undergraduate Honors Theses

This booklet is a collection of 6 case studies that utilize reused plastic bottles significantly within their design. Prior to working with the case studies, much time was dedicated to research that justified the need for such a project. In-depth research on the environmental crisis, waste management trends, stewardship, sustainability, and ethics was conducted and recorded in the introduction to contextualize the need for an accessible how-to guide such as this one. Time was also given to establishing background information on bottles, reprocessing, and architecture to elaborate further on each piece of the content matter. It is curated as a …

Intelligibility Of Medically Related Sentences In Quiet, Speech-Shaped Noise, And Hospital Noise, Tessa Bent, Melissa Baese-Berk, Erica E. Ryherd, Sidney Perry

Durham School of Architectural Engineering and Construction: Faculty Publications

Noise in healthcare settings, such as hospitals, often exceeds levels recommended by health organizations. Although researchers and medical professionals have raised concerns about the effect of these noise levels on spoken communication, objective measures of behavioral intelligibility in hospital noise are lacking. Further, no studies of intelligibility in hospital noise used medically relevant terminology, which may differentially impact intelligibility compared to standard terminology in speech perception research and is essential for ensuring ecological validity. Here, intelligibility was measured using online testing for 69 young adult listeners in three listening conditions (i.e., quiet, speech-shaped noise, and hospital noise: 23 listeners per …
