The Relationship Between Information Quality and Construction Safety

Attah, Aloysius 01 January 2019 (has links)
Fatal occupational injury is a construction and management problem in the United States. Fatality rates among specialty trade contractors made up the largest percent of fatalities in construction at 62% per year. The purpose of this nonexperimental study was to examine the relationship between the quality of information in construction safety plans and construction safety among specialty trade contractors. The theoretical foundations for the study were Petersen'€™s accident/incident theory and work systems theory. The key research question was to examine the relationship between information quality and construction safety among specialty trade contractors. A survey with closed-ended questions was used to collect primary data from a self-selection sample of 134 specialty trade contractors in the United States. Spearman rank correlation coefficient (rs) was used to measure the strength of the relationship between information quality and construction safety. Results indicated that the quality of information in construction safety plans (measured by the relevance, accuracy, timeliness, and completeness of information) did not have any statistically significant relationships with construction safety among U.S. specialty trade contractors. Further research is needed to understand if the variables used in this study are relevant predictors for construction safety. This study connects with positive social change by bringing into focus quality information systems research required to improve safety among U.S. specialty trade contractors and provide safety professionals a direction for continuous safety improvement in the U.S. construction industry, thus benefitting construction stake holders.

Significant Trade Contractor Performance Characteristics as Evaluated by Big-D Construction

Johnson, Conrad C. 20 March 2007 (has links) (PDF)
The purpose of this research is to determine which aspects, other than price, of trade contractor performance are the most important to the general contractor, Big-D Construction. The impression a trade contractor leaves on the project manager and superintendent provides an indication of their performance. To determine what tasks trade contractors perform that most greatly impact overall perception of the general contractor's project manager and superintendent, hundreds of trade contractors were evaluated in ten separate categories and were then given an overall rating. The correlation between each category and the overall rating was found. The categories were then sorted from highest correlation to lowest. Of the ten categories, professionalism had the highest correlation. Next to professionalism, schedule adherence was found to be most important. All of the next six categories: Coordination with other subs, quality of work, technical knowledge of drawings & specs, project close out (O&M's, punchlist, as-builts), monthly invoices - timely and accurate, and accuracy/timeliness of change orders, all had similar impact on overall performance. Daily clean-up and safety attitude, had the least impact on performance, with safety falling significantly lower than every other category. Overall, being professional, keeping to the schedule and doing good work are most important to project management teams, while keeping the job clean is noticeably less and safety is much less important.
