Office buildings listed into universal facilities buildings are one type of construction projects thatrequire a good project management to design, organize, perform and organize the construction project itself. Toachieve the success of the project needs to create a planning agenda that matches the wishes to be achieved. Ingeneral, project scheduling makes use of waku estimates of course. But the reality in the field of various obstaclesoccurred during the implementation of the project. therefore, researchers are trying to rescheduling theimplementation time of the Mess Building Renovation Project as well as supporting facilities of the BaliAgricultural Technology Assessment Office to recognize the maximum time of completion of the project. ProjectEvaluation and Review Technique (PERT) is one of the management tools in ensuring the scheduling of a projectby estimating the level of success. The pert procedure estimates 3 times is optimistic time, pessimistic time andvery maximum time. The level of accuracy estimated at the time of completion of the project is determined by thelevel of accuracy estimated the duration of each activity in the project. In analyzing calculations with the PERTmethod, an application-shaped tool, Microsoft Project, is used to manage projects. This application generallymakes it easier for users to create a work plan so that the implementation of the project can take place accordingto the agenda, mastering the influence of possible changes that occur, which can have an effect in the process ofproject implementation, financial scheduling and to unite businesses through communication and reporting ofproject data. Based on the results of the research that has been done, obtained optimistic project plan age of 128working days, the expected project plan age of 140 working days, the age of the pessimistic project plan of 153working days, and the optimum plan age (Te) of 141 working days.

Beams and plates are the dominant structural elements that receive unidirectional loads, so it is possible to use a system of prestress compared to columns. In this study, the analysis and design of prestressed beams were carried out in a building that functions as a hospital and previously analyzed using ordinary reinforced concrete. Beams and plates use a composite system and a prestressive system. The beam and plate are analyzed in two stages, the production stage and the composite stage after being installed on site. At the production stage, the beam height is reduced by the plate thickness and the load is calculated only for the prestress force and the lifting process. While the composite stage or after being assembled into one with columns and plates, all forces are calculated based on all the working loads. The concrete compressive strength and the yield strength of reinforcement used are 35 MPa and 360 MPa, respectively, while the yield strength of prestressed cables is 1860 MPa. The total loss of pre-stress force is taken as 25% of the total pre-stress force. Three types of beams have a span of 8 m, namely 40 x 60 cm, 35 x 55 cm and 30 x 50 cm after the composite, while the plate thickness is 15 cm after the composite and 10 cm during production. The analysis results show that the stress that occurs in the concrete beam and slab during production and when the composite with a prestressed system does not exceed the allowable stress in accordance with regulatory provisions. So that the prestressed beams and plates with the prestressed system can be applied in a composite system to the building structure and do not exceed the allowable stress limit for receiving loads.

Increased population, directly proportional to the increase in clean water needs. It also affects the availability of clean water both for current needs and for future time. To ensure that the availability of clean water can meet the needs of 2030, a study is needed to find out how much availability of clean water in 2030 and what needs are needed. To find out, a proper calculation method is needed. In this study, the availability of clean water in 2030 was calculated using the geometry method. Before calculating it, data on clean water availability was needed in the previous few years to find out the average growth of water availability which subsequently using geometry methods can be known to the availability of water by 2030. The results of the calculation showed that the availability of clean water in 2030 was 336.62 liters/second. Meanwhile, to calculate the need for clean water calculated using data on average clean water requirements today was then analyzed by the estimated population in 2030. The result was, the need for clean water in 2030 with the level of population at that time was 668,7756 liters/second. It can be concluded, the need for clean water in 2030 is greater than the availability of clean water. Therefore, looking for other important clean water sources is planned as early as possible so that water needs by 2030 are still fulfilled.

Reinforced concrete beams in this study are designed precast in site or cast before being installed in position. This beam is made only by casting the beam reduced by the thickness of the plate and without the top reinforcement, while the lower reinforcement and shear reinforcement is still installed as required from the analysis. The goal is to shorten the working time and get better concrete quality. This beam is part of the structural elements of a building that has been designed and analyzed in advance with a computer program based on structural analysis, SAP2000 v.16. Dimensions and reinforcement requirements from the results of the structural analysis are used as references to analyze precast in site beams. Main beam dimensions resulting from building structure analysis are B1, B2, and B3 with dimensions of 300x500 mm, but with different amounts of reinforcement requirements. Meanwhile, the joist (BA) has dimensions of 250x400 mm. Then the precast in site beams B1, B2, and B3 have dimensions of 300x350 mm and joists (BA) have dimensions of 250x250 mm after deducting the plate thickness of 150 mm. After being cast and dried at the planned age, the beam is then lifted and positioned on the column provided, after which the upper reinforcement and slab reinforcement are installed and cast again. Analysis of lifting or erection is also carried out to ensure that the working load does not exceed its capacity. The analysis results show that the precast beam is able to carry all the working loads and the precast in site system can be applied safely.

The need for concrete as a construction material to support infrastructure development is still very large, this is because concrete is still believed to be a reliable material for building construction. The availability of concrete mixtures in nature is running low because it continues to be taken for development. Realizing this, it is necessary to innovate in the future to find materials as a substitute for sand and coral, which are decreasing in number. This research tried to use the tile fragments of Banjar Tegal, Darmasaba, as a substitute for some of the coarse aggregate needed in the concrete mixture. The purpose of this study was to determine whether the Banjar Tegal tile fragments qualify as a concrete mixture according to the grading requirements, and how much compressive strength occurs. Tile fraction samples were taken in Banjar Tegal, Darmasaba, Abiansemal, Badung, while the research was carried out at the Concrete Laboratory, Faculty of Engineering, Unmas Denpasar. Tests were carried out using cylindrical specimens of size 15 x 30 cm, the mixture was made in five treatments with 8 pieces of each treatment, and testing was carried out on 28 days old concrete. The results show that the Banjar Tegal tile fragments can meet the requirements of aggregate gradation as a concrete mixture, and according to the laboratory test results the compressive strength of the concrete still meets the requirements in accordance with the concrete plan, but a slight decrease is proportional to the percentage of replacement made. The complete results are P0 = 237.74 Kg / Cm²; P1 = 234.63 Kg / Cm²; P2 = 232.05 Kg / Cm².; P3 = 229.22 Kg / Cm²; P4 = 225.27 Kg / Cm². Thus, the tile fragments of Banjar Tegal, Darmasaba can be used as a substitute for some of the coarse aggregate in the concrete mixture.

The problem of parking is very important to be studied more deeply, because almost all activities in open spaces require parking facilities. The required parking space must be provided adequately. On street parking is parking that takes place along the body of the road. This has a negative impact on the smooth flow of traffic, because it causes a reduction in the width of the road that is traversed. The aim of this research is to determine the characteristics of motorized vehicle parking and the shape of the parking angle pattern by considering the incidence of side friction factors. The vehicle parking area at Saraswati 1 Denpasar Senior High School has not received a touch of planning and arrangement, so this condition causes vehicle chaos and difficulty parking for users to get out and enter the parking location. By making a parking arrangement plan at the school, it is hoped that it will be able to accommodate the number of parked vehicles and facilitate access in and out of the vehicles themselves.
