The basement project that will build under the Pemuda-Yos Sudarso Surabaya road located in the center of Surabaya and the Class A cultural heritage area. The condition is likely to cause many problems during the construction. Such problems could be a risk factor and would affect the completion of the outcome of the work. Therefore the identification of risks to determine how to control risk becomes very important to improve the successful implementation of the project. This study uses questionnaire distributing instruments for respondents and interviews of resource persons deemed competent for risk allocation and risk response. Determination of risk identification variables based on common risk checking where initial risk identification is compiled based on interviews with competent resource persons, previous theoretical and research studies. Data analysis technique is assisted by probability impact matrix and statistical calculation to measure correlation level with Spearman rank followed by an interview with a resource to confirm risk allocation and risk response technique. There identified 28 (twenty-eight) risks; there are 4 (four) risks affecting the cost of completion of the project that is dominant (Unacceptable) and 16 (six)) risks including the category of being or not expected (Undesirable). For the risk of impacting project completion time, there are 5 (five) dominant risks and 17 (seventeen) risks including medium or unexpected category. From the analysis, there are 16 (sixteen) risks that correlate to cost and 23 (twenty-three) risks that correlate to the project completion time. There are 9 (nine) risks allocated by Owner, 4 (four) risks allocated by Design Consultant 8 (eight) risks ownership of Contractor, 1 (one) risk allocation of Supervisory Consultant/CM, 4 (four) risks allocated by Service Provider (Designer, Supervisor / CM, & Contractor), 4 (four) risks as joint risks.
