Overexertion Injuries in Construction
(American Society of Civil Engineers, 1999)Overexertion injuries are the single largest classification of injury in construction, accounting for about 24% of all injuries. Overexertion injuries generally occur as a result of performing a given task as planned. While ... -
Small to Medium Contractor Contingency and Assumption of Risk
(American Society of Civil Engineers, 1999)This paper is the result of an investigation into the use of contingency in smaller construction firms. It summarizes recent literature classifying construction contract risks and mitigation measures. Eight major classifications ... -
Effect of Cooling by Water Flowing in Nonmetal Pipes Embedded in Mass Concrete
(American Society of Civil Engineers, 1999)Although roller compacted concrete was developed in recent years, artificial pipe cooling still is used widely to control the temperature of mass concrete in dam construction. There is a tendency to replace the metal pipes ... -
Physiological Demands of Concrete Slab Placing and Finishing Work
(American Society of Civil Engineers, 1999)Construction craft work is physically demanding. As a result, many craft workers become excessively fatigued, which may lead to decreased productivity and motivation, inattentiveness, poor judgment, poor quality work, job ... -
Effective Construction Site Management: A Review
(American Society of Civil Engineers, 1984)The contribution of site management to the achievement of construction performance objectives is examined. Drawing upon existing empirical data and linking them with research findings in the social sciences, the writers ... -
Mathematical Models for Maximizing Aggregate Plant Production
(American Society of Civil Engineers, 1999)An aggregate production plant mainly consists of conveyors, crushers, and screens. How to set up the closed-side openings of crushers and the openings of screens is an important issue for the plant manager in order to ... -
Loss of Labor Productivity due to Delivery Methods and Weather
(American Society of Civil Engineers, 1999)This paper describes three structural steel erection projects that used different methods of delivering the structural steel members. Two projects scheduled daily deliveries. On one project, steel was erected directly from ... -
Genetic Algorithms Application and Testing for Equipment Selection
(American Society of Civil Engineers, 1999)This paper describes a research undertaken at South Bank University that investigated the feasibility of applying artificial intelligence methodologies to the optimization of excavating and haulage operations and the ... -
Multiheuristic Approach for Resource Leveling Problem in Construction Engineering: Hybrid Approach
(American Society of Civil Engineers, 1999)The fluctuation of required resources causes problems in construction scheduling. Thus, researchers developed resource leveling techniques to minimize the deviation between the resource requirements and the desired resource ... -
Effect of Truck Payload Weight on Production
(American Society of Civil Engineers, 1999)Most constructors intuitively understand that there is a relationship between payload weight and haul unit performance. At the same time, project managers constantly push the limits of rated truck payload as they seek ... -
Simplified Program Evaluation and Review Technique (PERT)
(American Society of Civil Engineers, 1999)A simplified version of the program evaluation and review technique (PERT) for project planning is developed and tested. The simplification is to reduce the number of estimates required for activity durations from three, ... -
Construction Labor Productivity Modeling with Neural Networks
(American Society of Civil Engineers, 1998)Construction labor productivity is affected by several factors. Modeling of construction labor productivity could be challenging when effects of multiple factors are considered simultaneously. In this paper a methodology ... -
Multiskilled Labor Utilization Strategies in Construction
(American Society of Civil Engineers, 1998)Construction industry craft divisions in the United States are currently based on narrowly defined skill groupings. The steady demand for improved productivity and the shortage of skilled craft workers call into question ... -
A Better Way to Estimate and Mitigate Disruption
(American Society of Civil Engineers, 1998)The construction industry has a difficult time prospectively identifying, with accuracy, either the scope or magnitude of change-caused disruption at the activity level. This difficulty increases contractors' risks when ... -
Is Injury Occurrence Related to Lunar Cycles?
(American Society of Civil Engineers, 1984)Injury data were analyzed to determine if any relationship existed between the dates of injury occurrences and the varying positions of the moon. Since the analysis of injury data from a single construction project yielded ... -
Model for Public Sector Design-Build Project Selection
(American Society of Civil Engineers, 1998)Public sector owners are rapidly identifying new construction procurement methods. Changing procurement laws and documented project success are encouraging owners to attempt the design-build method of project procurement. ... -
Guidelines for Quarrystone Armor Units
(American Society of Civil Engineers, 1998)Guidelines are provided for inspection and selective placement of quarrystone armor units used for breakwaters, jetties, and revetments. General guidelines are suggested for procurement and inspection of stone at quarries, ... -
Business Failures: Liabilities of Newness, Adolescence, and Smallness
(American Society of Civil Engineers, 1998)The contextual factors of a company, particularly age and size, are commonly argued to have important implications on its survival chances. The research presented in this paper explores these implications in the context ... -
Managing Industrial Construction Safety in Southeast Texas
(American Society of Civil Engineers, 1998)The construction industry on average has a higher rate of occupational injury than most other industries. However, steps can be taken to reduce worker risk through the effective management of controllable factors. These ... -
Assessing Cost Uncertainty: Lessons from Environmental Restoration Projects
(American Society of Civil Engineers, 1998)The uncertain physical and regulatory conditions prevalent in the field of environmental restoration often lead to considerable project cost growth. To date, the ability of project personnel to predict the magnitude of ...
