The overall aim of this thesis is to develop reliable methods of measuring output levels for construction plant and labour, with a view to establishing realistic output rates for concreting operations. This thesis demonstrates that most of the variability in production rates can be quickly explained, leaving relatively constant levels of output f or individual construction operations (i.e. basic operation times). The primary factors in determining output rates were found to be work rate, delays and waiting caused by poor management, and poor motivation. The latter two items accounted f or more than fifty per cent of the available working time on many sites, whereas work rate varied only slightly. This last finding may be surprising, but the results indicated that when work was being done the effort applied appeared fairly constant to the observer. However, the time spent working was largely dependent upon the level of motivation induced through the payment system. Where a combination of good direct supervision and satisfactory financial incentives were present, high levels of motivation were observed, conversely, low motivation occurred on sites where minimum day-work payments were present. Investigations into several construction trades indicate that work study techniques can be modified to meet the requirements of most construction operations, sites and companies, whether the requirements be a complex synthesis of basic operation times or the more simple determination of site efficiency. The key to this portability lies in the isolation of basic operation times via the application of site efficiency factors. In this thesis, primary work study techniques are identified and discussed. The need for specific construction work study techniques is shown to be of paramount importance. The results from over seventy concrete pours are combined and statistically analysed to produce realistic output rates arid current levels of production. Site factors are combined and statistically analysed to produce a relationship between efficiency and level of remuneration. A comparison is drawn between: the production rates achieved on several sites; and the output rates currently being used in the planning and estimating processes.

This thesis is intended to address the need for ornamental iron classes at the senior high school level.

In recent decades, the demand for a wide variety of products, lead to the requirement of having a reduced cost of manufacturing, shorter cycle times and perfect quality; forcing companies to implement different engineering techniques to have the best manufacturing system. With which it seeks to efficiently control the process, provide an optimal area of work, establish performance standards with respect to the operations that the company performs, thus generating better results in the organization to achieve higher levels of user satisfaction. In the case of the study, the main line of production in the company was analyzed, detecting that representative costs originated from reprocessing and downtime. The result of greater impact obtained was the reduction of the problems in one (60%) and (15%) respectively. In this way, it is expected that companies in the paint industry or products related to the sector can use the results obtained as a reference in their process of continuous improvement, improving the management and performance of the organization and customer satisfaction.

In a General Metal Shop, Art Metalwork is one of the activities used to round out a general study of the metals field. That it is a valid subject to be taught in this field of activity is shown by the fact that Art Metalwork is included as a center of activity in a number of state studies in the Industrial Arts curriculum. The Pennsylvania state study of Industrial Arts lists Art Metalwork as a center of activity in the Metals area. The Connecticut state study in Industrial Arts lists Art Metal under General Metalwork. The New York state course for Industrial Arts also includes Art Metalwork as a center of activity in General Metalwork.
