Key Success Factors for Critical Chain Project Management (CCPM) and 4D Building Information Modeling (BIM) for Improving Time Performance in Basement Work on 5 Layers of High-rise Residential Buildings in Indonesia

Abstract

Referring to data released by The Skyscrapper Center in 2020, during the period 1960 - 2020 there was a rapid increase in the construction of buildings with a height of more than 150 meters around the world. The increase in high-rise residential buildings or high rise buildings according to the global competitiveness report data from 2014 - 2020 will be the largest growth country in the construction sector with an average total growth value of 6.3% so that engineers - architecture carry out and make project management engineering from the initial project phase to the project completion phase and the increasing complexity of problems in the planning process to the management of high-rise residential buildings. The need for housing in Indonesia, especially in big cities, is high and the limited availability of land causes prices to increase, so that investment in residential high rise buildings is growing rapidly. The high demand for the community is directly proportional to the increase in the number of residential building construction for high-rise buildings. Building construction is expected by service providers to be completed on time without delay according to their planning. However, in the implementation of development there are problems that cause delays in its implementation. The delay that occurs can be from internal, external and weather factors. For this reason, this research will discuss the key success factors of critical chain project management (CCPM) and 4D building information modeling (BIM) for improving time performance on the basement work of 5 layers of high-rise residential buildings. To obtain the key success factors, the researchers used the SPSS (Statistical product and service solutions) tool. From the results of this SPSS, the researchers found 10 key success factors, namely 1. Project identification against time, 2. Basement design complexity, 3. Effect of project buffers, fedding buffer , buffer resources, 4. Accuracy of document design, 5. Scheduling and Simulation, 6. Logical relations of activities, 7. Policy and government support, 8. Top down methods, 9. Land conditions, and 10. Eliminating safety time. The 10 key success factors are expected to reduce delays in the implementation of development.
