ABSTRACT
High Rise Building project has a very high work complexity so that the probability of the risk is enormous. The risks are likely to occur can inhibit the work of the project and can affect costs. It is therefore necessary to risk management to minimize the impacts caused by therisk. This research aims to know the factor dominant risk on construction projects that have an impact on costs. Identification of risk review of aspects of the internal non technical : construction management cost, risk, uncertainty work, terlamba t his project, the uncertainties of material and equipment. The methods used by conducting a detailed questionnaire on the project of High Rise Building. Methods of analysis using the method of Pearson. The dominant risk analysis obtained from the main questionnaire and is calculated based on the method of the concept of Severity Index (SI) as well as the measurement of the value of the level of risk. Analysis on the dominant risk against 12 can cost. The most dominant risk impacting on the cost of the plan is the owner of the project fee usually varies due to the risk of total value could reach 10% of the contract value.
