  • Construction companies are now trying a variety of cost-cutting strategies in the midst of recent slump of construction market. Notably, contract workers and local hires are accounting for increasing portion of management manpower as a part of their cost-reduction drive. However, construction site manpower researches to date have focused primarily on productivity analysis of site laborers, with little attention to the productivity of site management resources. This study aims to analyze the staffing status of office building construction site management manpower in reference to project size. Conclusions herein will provide basic inputs for subsequent attempts to build a model to enable efficient staffing of construction site management manpower.

  • In the highly competitive construction industry, a slight inaccuracy of estimation can easily cause the loss of a project. Erroneous experience-based cost estimates or allocations of on-site supervisory manpower often offset the profit gained from the project and may jeopardize the management processes. To counter these types of problems, we develop a model using mathematical analysis and case-based reasoning to automate the allocation of on-site supervisory manpower and estimate construction site costs. The method is founded upon laborious data collection processes and analysis by matching statistical assumptions, and is applicable to construction projects. In the modeling the costs and allocation of on-site supervisory manpower are quantified for both owners and contractors before initiating or bidding on the projects. The findings confirm that the degree of variation of the model predictions has an accuracy rate at 88.47%. Single-site construction projects can be accurately predicted and the assignment of supervisory manpower feasibly automated.

  • As the recent economic downturn continues to undermine the profits of construction industry in Korea, it has become ever more pressing to improve productivity of the industry. Since construction site management manpower staffing plan has close bearing on the productivity of construction projects, it is essential to estimate and mobilize adequate number of resources as per conditions and characteristics of each construction site. However, there are no reference approaches in practice to provide baseline for site management manpower staffing plan or estimation of manpower requirement. Therefore, this study aims to examine factors affecting productivity that warrants first and foremost consideration in development of site management manpower staffing plan during the initial phase of building construction project by conducting survey on industry stakehoders with hands-on responsibilities in construction sites and analyzing their responses. Conclusions herein will provide basic inputs for subsequent studies on development of site management manpower staffing plan as per project characteristics.

  • Recent economic slump has highlighted the needs for the construction industry to develop strategies to improve productivity and overhaul organization structure. Notably, it is urgent to improve productivity of apartment building construction projects that account for about half of the aggregate revenue of building construction projects in Korea. As construction site management manpower staffing plan has close relation with the productivity of building construction, it is essential to staff construction sites adequately in consideration of site conditions and characteristics. However, construction companies of Korea are still far from developing site management manpower staffing plan in reference to quantitative standards. Therefore, this research aims to analyze site management manpower staffing plan of apartment building construction project by means of density analysis. To be more specific, site organization charts and staffing plans of apartment building construction projects put together by large construction companies in Korea are studied and essential resources and their mobilization time of apartment building construction projects are examined. Conclusions herein will provide basic inputs to subsequent studies of apartment building construction site management manpower staffing standards.

  • This study clarified the fact that the existing 'manpower supply and demand plans', preceding studies, theoretical researches of the past cannot satisfy the multi-goals of organizations, instead, the existing plans focused on only the number of customers and total amount of service. Next, a necessity of more proper manpower plans that consider comprehensive goals of the organizations is suggested then, this study tried to make the countermeasures. As for studying methods, a priority sequence in the organizations' manpower management's goals is set by AHP(Analytic Hierarchy Process), a business administrative scientific skill. Proper manpower policies of the food service enterprises, which satisfy the organizations' multi-goals, are established by GP(Goal Programming). Based on it, mid and short term 'manpower supply and demand plans' are established. For the purpose of increasing the study's efficiency, example studies are conducted in one family restaurant. The limit of this study is that inner personnel management details such as promotion, new personnel appointments, unemployment, retirement were not considerately considered. Therefore, the future studies should think over those limits and research the labor-force supply from the outside also.

  • Recently, Housing projects in the center of the Metropolis are getting higher, larger, more complex gradually, the resources are increasing greatly. Especially, the right manpower in the right place could quite important factor because the construction cites are wide and many subcontractors and labors throw into finish works in High-rise Housing projects. Differing from apartment building projects. it is only four or five years that high rise building projects are started so, there is little data for manpower information. Furthermore it is difficult that the data gathering and managing because manpower management is usually used to execute by subcontractors from supply to demand. Consequently, this study, proposed develop management for accurate manpower plan and efficient collection and practical use of manpower information through analysis of present condition in construction sites

  • Construction companies find it increasingly necessary to reduce the cost as the construction market has been suffering from a depression and the industrial environment has been changing fast lately. The cost cut demands the productivity management of the field operations, which can be made feasible by assigning an appropriate number of managers on the construction site. However, previous studies are focused on the labor productivity and construction companies take into account only the revenue per worker in organizing the staff. The purpose of this study is to research the model for calculating the field management manpower in accordance with the characteristic of project and site conditions which are usually considered in the beginning of the construction project. The data about apartment building projects of domestic large constructors and factors related to them were statistically analyzed. The results of this study can be used to calculate the necessary field management manpower in accordance with the characteristic of project.
