ASSESSMENT OF GANG SIZE OUTPUT ON CONSTRUCTION SITES. A RESEARCH PROJECT MATERIAL ON MECHANICAL ENGINEERING
The construction industry is that sector of national economy that is responsible for the development of both structures and infrastructures. It embraces “a wide range of loosely integrated organizations that collectively construct, alter and repair a wide range of different range of building and civil engineering structures” (Seeley, 1984).
Smith and Katzenback (1987) define work team (gang size) as “a small number of people with complementary skills who are committed to a common purpose, performance goals, and approach for which they hold themselves mutually accountable” Although work team effectiveness is complex a subject, optimum work teams have some common characteristics. Such characteristics include relatively small size, dedication standards, willingness to be collectively accountable, equitable and effective work and role assignment procedures within the team, and complementary skills. Optimum work teams also require compensation approaches that reward teamwork, such as gain sharing or team bonuses.
Abiola (2004); Define productivity as a measure of how efficient and effective the resources, labour, capital, material, energy, water, information technology, etc. are used to produce the goods and services needed by the society.
According to Longman dictionary, output can be defined as “the amount of goods or work produced by a person, machine, and factory.”
Management is getting results through workers’ output, as such, became the essential requirement in accomplishing the desired result. If a manager has more work to do than he can carry out personally, he gets it done by others (especially the hard labour).Productivity improvement is concerned with raising output and reducing costs and therefore the profitability of the construction industry. In many organizations improved utilization of man power assets is the key to the significance of short and long term productivity improvements. Improving productivity is part of the job of every line manager because of the direct link between productivity and profitability. Increasing use of people (increasing output and reducing cost) can only be achieved by optimum gang size, supervision and management. It is the responsibility of the top management to formulate company or industry policies for human errors in bid to improve managerial productivity, (Osoba, 1983,etal). In the pursuit of human errors reduction for productivity improvements there are certain factors to be considered because their influence can be readily modified and they include:
