PT. Tunas Jaya Sanur, one of the big construction companies, always deals with the market segment's changing conditions. The better the market conditions, the greater the chance to get the project, and vice versa. The study's first objective is to identify the factors that have a dominant influence on Bali contractors' tenders' success in project tenders throughout Indonesia, especially PT. Tunas Jaya Sanur. The study shows two factors that positively affect the ratio of successful tender values: factors of quality of work and human resources (Xb1) and support factors for external resources and communications (Xb2). Furthermore, the researchers conduct modeling with multiple linear regression and obtain the equation, namely Y = 3.583 + 0.472 Xb1 + 0.611Xb2. The equation shows that the two independent variables positively influence the value of a successful project tender. The increase in one of the two independent variables will also increase a successful project tender value.
