Abstract

The construction development which grows fast in Indonesia is causing needs of supporting technology that give more efficiency yet it also has to be more effective. Technological developments in the field of construction is giving a system called Building Information Modelling (BIM) as a result. Before BIM, we already aware of AutoCAD, SAP, Ms.Project that have been used for project planning, the use of these softwares take a lot of time because they can’t be integrated, so it need more cost, human resources and time to for a project planning. BIM encourage the exchange between different diciplines, so that this exchange process could get faster and affecting the costruction itself in a good way. Currently in Indonesia, there are a lot of construction workers who haven’t use BIM technology, even acknowledge about the benefits it gave, while in fact, BIM have so many excellences compared to the common technology that have been used. Thus, writers do this research to acknowledge about comparison between BIM and conventional methods. Writers are using three methods, they are questionnaires, interviews and a case study, to acknowledge about the performance of BIM. With case studies planning of 20 storey building made comparisons between the efficiency of conventional methods with BIM concept in need of time, human resources and costs for project planning.This study concluded that the use of the application with the concept of BIM can accelerate project planning time by ± 50%, BIM reduces the human resources needs by 26,66%, and saving personnel costs to 52,25% as compared to using conventional method.

Abstract

The economic growth has contributed to the increasing number of high rise building construction mostly in big city especially Jakarta. In practice, the construction of high rise building project is aided by heavy equipment that is hammer head crane which is known as one of tower crane type. However, with the increasing number of high rise building construction, the hammer head crane space that usually be used in high rise building project is limited, hence, another type of tower crane called luffing crane that can be working optimally in the limited space is needed as the alternative for hammer head crane. For the consideration in choosing the type of which tower crane that should be used in the project, it requires the productivity analysis that is related to the equipment efficiency for each column, slab and beam works. From the research that has been conducted, it shows that the hammer head crane productivity is 13% higher fo column work and 65% higher for slab and beam works than luffing crane’s. With a note that in horizontal movement, luffing crane is excel more than hammer head crane. So overall, it can be concluded that in a condition where hammer head crane still can be operated in a limited space, its productivity is still higher than luffing crane productivity that operated in the same condition and surrounded. While luffing crane is used if hammer head crane is utterly can not be operated.
