Abstract

When carrying out a construction project activity, a construction management system is needed. ConstructionManagement includes management of project cost control (RAB), time (Schedule), human resources (HR),project occupational health safety management (SMK3L) and risk classification and control. Projectimplementation control must be carried out from the beginning of the work until the project work is completedso that construction management must be by the implementation. The results of the review of constructionmanagement planning for the construction of the NAPZA building were dominant in the implementation phase,especially in time control where the project construction process which was originally planned for 148 daysor approximately 22 weeks became 24 weeks. This resulted in the problem of processing time where the targetwas not achieved and resulted in delayed project work. Project implementation control must be carried outfrom the start of work until the project is declared complete so that during the project development processunwanted problems can be avoided. The construction management that will be applied to the NAPZA buildingcan make the project run well and according to the desired schedule.

Abstract

The number of intersections with adjacent intersections in Pontianak City raises its own problems, one of which is the signalized intersection on Jalan KH. Ahmad Dahlan Pontianak. The short - term strategy to overcome these problems is traffic management and engineering to improve traffic flow based on field condition evaluation . Data collection was carried out by means of direct surveys at both intersections. The data obtained is used to obtain the existing conditions which will be a reference in planning a new cycle time by taking into account the coordination theory. Meanwhile, in calculating to get the best performance at each intersection, it is done using the MKJI approach. The best performance at each intersection is then coordinated using the green time between intersections. The results of the analysis of the performance of the existing conditions show that the degree of saturation is DS = 0.86 for signalized intersection 4 and DS = 0.68 for signalized intersection 3 which are not too different from what MKJI requires, DS = 0.75 , but it is not comfortable and safe to go through. From the queue length (QL) at the four intersection of 288 meters > the distance between the intersections which is 200 meters apart, and also from the delay time (DQ) of 66.03 seconds > from the green cycle time of 25 seconds, After knowing the performance of the existing intersection, then create a new cycle time planning for both intersections. The new cycle time with the best performance will be used to coordinate the two intersections. Selection of the best cycle time by comparing the values ​​of the degree of saturation (DS), the length of the queue (QL), and the delay (Delay) from several alternatives that were carried out. From the results of the study, a new cycle time of 95 seconds was obtained. The offset time used is 36 seconds, and the bandwidth from East to West and from West to East is 16 seconds. With the new cycle time the performance values ​​of the two intersections get better because the average delay and queue length decrease, for intersection 4 (DS = 0.76; QL = 136 m; DQ = 67 seconds) and intersection 3 (DS = 0, 67; QL = 94.5 m ; DQ = 65.37 seconds),
