Means of transportation at present is very important to continue to be built effectively and efficiently to the level of fluency and accuracy of time toward the goal easier and faster and to meet minimum service standards of the highway. In line with that so that the toll road remain in the minimum service standards need to be additional road capacity to effectively and efficiently for that it is necessary to study whether the possible acceleration of road capacity expansion projects, so that the level of minimum service standards can be maintained and to what extent the effect of accelerating the schedule project on development costs.One method that can be used to analyze the effect of accelerating the project towards the costs is to analyze the exchange of money and time (time cost trade off).Variables used in the calculation of "Acceleration Schedule of Construction and Completion Costs Effect on Construction Project "is the direct labor, equipment, overtime working hours, method of construction, all have an influence on the different costs, acceleration (crash) or compression of time that have done the job and the biggest costs related to the work that has the greatest cost , a benefit if the toll road opened in advance of the acceleration due to a smaller project compared to the costs required for expediting the project construction on this project, based on the cost of the acceleration is not necessary because the costs to perform a greater acceleration when compared with a benefit.

In the implementation of construction project activities there are thre things that influence the success and failure of the project: time, cost and quality. The success of a project is usually seen from the timing of completion which is relatively short but without neglecting the quality of the project work. Appropriate and targeted project management and management are required to ensure the time, cost, and quality of the project. This is certainly to avoid a variety of undesirable things such as late settlement, swelling costs, quality failures, and so on that could have an impact on project failure and the emergence of the cost of fines. The purpose of this study is to calculate changes in cost and time of project implementation with alternatives to additional working hours (overtime) comparing the results between normal and cost changes after the addition of working hours (overtime). The data used in this research is secondary data obtained from contractor implementing. Arrow diagram The results program are critical paths and cost increases due to the addition of working hours (overtime) while the result of the time cost trade off method is the acceleration of duration and the increased cost due to the acceleration of duration in any accelerated activity. The results of this study indicate that the total project time and cost under normal conditions is 508 days at a cost of Rp 22.240.655.701  with the addition of 3 hours of overtime work in the duration of crashing 485 days and at a cost of Rp 23.252.220.373,34

In analyzing the comparison of the cost of acceleration with the acceleration time used by the method Time Cost Trade Off. The analysis is done by using / shortening (crashing) time of implementation by using an alternative to increase working hours (overtime) for 3 hours. With apply the TCTO analysis, the implementation of the construction of the Sei Hanyu Bridge project after its duration performed calculations using the crash duration method, it was found that the time needed to accelerate the construction of the Sei Hanyu Bridge in Kapuas Regency for 1038 calendar days(148 weeks), can be accelerated 44 days from the original planning 1082 calendar days (155 weeks). With the acceleration of the completion of the construction of the Sei Hanyu bridge in Kapuas Regency, an additional fee of Rp. 175,160,710.43 is required with an additional cost (cost slope) of Rp 3,980,925.24 per day for 44 days, so the optimal costs needed to accelerate the construction of the Sei Hanyu bridge in Kapuas Regency was Rp. 45,102,729,928.11 originally planned for Rp.44,927,569,217.68

Construction project management is one of the things that affect the smooth work of construction projects. Time and cost become benchmarks in the success of a project. In the construction project Bhayangkara Nganjuk hospital indicated experiencing delays caused by unse endorsive weather conditions. The delay will have an impact on the costs that will be incurred. The purpose of this research is to accelerate the time on the project by using the time cost trade off method. Development work includes IGD room work, Pharmaceutical Installation, Laboratory and Inpatiation Room. The data used in the form of Time schedule and budget plan costs obtained from the implementing contractor. From the data, analysis is carried out in the form of determination of relationships between jobs, determination of critical pathways, and acceleration analysis by applying a work shift system. The relationship between jobs is illustrated through the Microsoft Project. The results of the study obtained a total cost after acceleration of Rp. 3,873,505,632.00 the value was more expensive 11.25% than the normal cost of the project of Rp 3,481,698,000.00. With an accelerated duration of 125 days or 25.71% faster than the normal duration of the project of 180 days. So that from these results, it can be used as a reference in the implementation of the project regarding work hours that can be applied as well as the cost of the project and the duration of acceleration required.

Cost overrun in the field of project construction is still a global issue, and it is a challenge to seek for solution from various scientific discipline including information technology. This thesis aims to design a business intelligence application model for analyzing the cost of construction project to provide follow-up information as quickly and as early as possible to assist the executives to make valuable business decisions. This case study was prepared through literature reviews, interviews, and direct observation to obtain overview of the business processes in the construction company. The modeling of BI application which can be successfully developed using agile methods is very effective in addressing the change. This case study found that the application of business intelligence which provides information on key performance indicator (KPI) can assist the executives of the company to make decisions quickly and precisely, thus improving the performance of the project, especially in the cost control.

Construction Project Scheduling

The increasing number of construction projects together with the limited resources of organizations led to tough competition for achieving project goals. Time, cost, and quality have been known as the project iron triangle. Project managers attempt to allocate the appropriate resources and make the best decisions for accomplishing projects with the shortest durations, lowest costs, and the highest quality. No study has examined the time–cost–quality trade-off problem with decision-making approaches. In this study, the fuzzy multi-criteria decision-making (MCDM) methods are exploited to choose the best mode for performing each activity. For this purpose, the SWARA method is applied to determine the importance weights of time, cost, and quality. In addition, the TOPSIS (Technique for the Order Preference by Similarity to Ideal Solution) technique is used to rank and select the best activity execution modes. The proposed model is implemented on two medium- and large-size construction projects to evaluate its efficiency. Several execution modes with fuzzy duration, cost, and quality are considered for each project activity. Finally, sensitivity analysis is conducted taking three different conditions into account: the shortest duration of the execution modes, the lowest cost of the execution modes, and the highest quality of execution modes for each activity. The solution of each trade-off is compared with the solution obtained from the fuzzy SWARA–TOPSIS method. The schedule is developed according to the best execution mode for each project activity. The obtained results in two different construction projects show significant improvements in the overall project objectives so that the projects can be completed in fewer durations and costs along with higher quality. Because of the higher importance of cost, the cost of each activity is closer to the lowest cost. The activity duration is also closer to the most likely duration, and quality is closer to the high-quality level. The application of this approach can create new opportunities for research and knowledge development in the field of construction project scheduling.
