Safety at the location of road works is an important part that is often overlooked in the construction and maintenance of roads. Management of the safety of the road work location is the responsibility of the road manager. In general, knowledge about Occupational Health and Safety (OSH) is very broad, but there are several OHS components that are considered important to be used as a benchmark for understanding OSH. These components are K3 Definition and Initiation, K3 Management System (SMK3), Personal Protective Equipment (PPE), K3 Facilities and Infrastructure, OHS Risk. Research on the influence of occupational safety and health knowledge on occupational health on construction worker behavior was carried out to determine the effect of K3 knowledge variables together on the behavior of construction workers. And to know the effect of K3 knowledge variables partially on the behavior of construction workers. From the results of the study it can be concluded that there is a relationship or a low level of correlation between K3 Knowledge and Workers' Behavior while the value of the Determination Coefficient (adjusted r square) is 0.033 which means only 3.3% of K3 Knowledge aspects that affect Construction Worker Behavior and the remaining 96.7% is influenced by other variables. Based on the results of the T-test calculation using the method of calculation of Multiple Linear Regression the value of t count

Control in a construction project generally involves three main aspects, namely: cost, time and human resources. This study uses Network Planning analysis as a control function with the Critical Path Method (CPM) method in calculating the difference in cost and time needed to complete the work with a planned budget and schedule. This study also tried to implement an integrated control function, namely the Earned Value Method for a construction project. Based on the analysis and calculation in the 8th week (eight) of the total duration of the project, the analysis produces CPI value = 1.06 which shows that the performance of contractor's expenditure costs is more efficient than the planned budget. The description of the final condition of the project also shows that there is a residual budget value of Rp 321,642,608.01 or 5.55% of the total value of the overall project cost budget or Budgeted At Completion (BAC) which is an advantage for the contractor. The analysis also produces SPI value = 0.94 which means that the time performance index is of good value but the execution of the work is a little slower than the overall planned schedule.
