Abstract
The goal of construction management is to manage with quality, time and cost of construction projects. The construction project experiences a delay, low quality, over budget due to negative factors cause of the direct stakeholders in the project. This research presents an analysis of the negative factor severity in the construction project by inquiring the direct stakeholder in the construction projects, consisting of 3 groups according to their roles and responsibilities. The analyzes in the severity by ranking with severity index, and risk level by matrix risk, were carried out to find negative factors in the quality, time, and cost that must be managed before getting a problem. The results showed that the negative factors must be immediately terminated in these three dimensions as follows, factors from the employer group (determining the clear scope and purpose of the construction work, delaying the decision-making process, and the construction changes), factors from the designer and inspector groups (the correct design, and roles and duties of inspector and controller), and factors from the contractor group (the labor shortage, and the contractor errors). The results showed that the relationship due to errors in the pre-construction phase directly affected the construction phase. Therefore, the negative factors occurring over the pre-construction phase should first be managed to prevent the impact going on during the construction phase.
