Penentuan Peringkat Faktor Risiko Dalam Rekrutmen Tenaga Kerja Yang Mempengaruhi Biaya Tenaga Kerja Pada Proyek

. In labor recruitment, there are several factors that affect the labor costs. These factors can disrupt the project execution and can cause variances in labor costs. These variances need to be analyzed through the roots of the causes and to be corrected. Deciding the proper corrective action is part of a decision making analysis,where risk analysis is included. Determining the risk ranks from the factors in labor recruitment could support in attaining the suitable corrective action in order to anticipate any variances occurred. AHP (Analytical Hierarchial Process) method can be used to determine the weight/score of the factors. Factors that have high ranks (with high weighted factor) are factors with high risk priorities that need to be assessed and handle

Rekomendasi Tindakan Koreksi Terhadap Penyimpangan Biaya Pembelian Material Konstruksi

. In delivering construction projects, is not uncommon that cost overrun occur due to variation on materials, equipments, labors, subcontractors, overhead, and general condition. Material contributes around half of the construction project, which make material management becomes an important element in project cost control. And in managing construction materials, purchasing has become major influence on material cost. Corrective actions on cost overrun can be used to overcome the cost variance due to poor material purchasing. This paper is aimed at identifying what causes of purchasing material cost variances and correctice action recommendation. Research method to identifying purchasing material cost variance and corrective action recommendation using questionnaire survey and interview distributed to high rise building projects. Analyze method using analytical hierarchy process (AHP) and Delphi method. The result show that corrective action recommendationon purchasing material cost overrun is preventif action (before process variance)

Two-envelope system for consultant selection using Weighted Sum Model

© 2018 Authors. Consultant Selection is one of a classical problem in Multi Criteria Decision Making (MCDM). Most of the literature in Operation Research only concentrates on model building rather than developing an inclusive analytic tool that extends to a Decision Support System (DSS). In this paper, we deploy a case study approach to understand the user requirement for DSS development. We observe the process of consultant selection and the decision making at one of the technical department which involve in the infrastructure project in Malaysia. A two-envelope system and a simple Weighted Sum Model are currently in use. We demonstrate the abstraction and application based on two case projects. Sensitivity analysis is also performed and the result shows that the decision changed if it is solely based on fees or with minimal quality criteria. Finally, we gather the findings from the organizational flows, user modelling and decision making process in order to benchmark with our future works. This will helps us to better understand and develop an improved decision support model or tools for consultant selection problem

The concept of constructability is to use construction knowledge and experience during all phases of a project, particularly in the earliest phases of planning and design. It facilitates project objectives before delivery stage, and decreases unnecessary costs during construction phase. Despite the extensive use, constructability concept fails to address many issues related to Operation and Maintenance (O&M) of construction projects. Extending constructability concept, to include the O&M issues, could lead to the projects that are not fitted for construction purposes only, but also fitted for use. This study reviews the literature of constructability implementation, its benefits and shortcomings during the infrastructure life cycle, as well as the delivery success factors of infrastructure projects. This contributes to the propose need of a model to improve the effectiveness and efficiency of infrastructure project by extending the concept of constructability to include O&M. Development of such a model can facilitate post-occupancy stakeholders' participation in a constructability program. It will help infrastructure owners eliminate project reworks, and improve O&M effectiveness and efficiency

Enhancing Construction Education in Indonesia through Links with International Institutions

The construction sector is particularly important to any national economy as it provides the infrastructure needed for many other sectors of the economy. In Indonesia, a developing country, contribution of the construction sector to the GDP increased from 4% in 1973 to 7% in 1994. This increase, however, is still relatively low compared to many of those in the developed countries which are typically greater than 9%. One factor, which could contribute to the relatively low contribution to the GDP, is a lack of adequate human resources in terms of quantity and quality when managing construction projects. The education and training of construction personnel in Indonesia is still far from adequate in providing the needed professionalism to manage major construction projects. Contributing to this inadequate training is a lack of university teaching professionals in the construction field. To fulfil the educational demand of construction professionals in Indonesia, an education and training scheme significantly different to the current system is required. One such scheme relies on the development of academic and research linkages with education institutions in developed countries. This paper will present several alternative programs that have been developed or are currently being investigated for construction education in Indonesia. This paper highlights the particularly successful Master of Construction Management degree at the University of Indonesia – a program which utilises imported expertise from the School of Construction Management and Property, Queensland University of Technology, Australia
