Abstract

The implementation of construction work has the main targets in construction management, such as construction costs, quality of construction work and construction implementation time. Construction activities can be declared successful in their management if they produce work products with the quality criteria that have been determined, on time, and according to the agreed costs. Using EVM (Earned Value Method) in project management can be used to determine cost performance and implementation time during the project and the indicators used for analysis include: BCWP (Budget Cost of Work Performance), BCWS (Budget Cost of Work Schedule), ACWP (Actual Cost of Work Performance), SV (Schedule Variance), CV (Cost Variance), SPI (Schedule Performance Index), CPI (Cost Performance Index), EAS (Estimated At Schedule) and ETS (Estimated Temporary Schedule). By using this method in the Sports Facilities Construction Project, Kecamatan Kedewan, Kabupaten Bojonegoro, the ACWP (Actual Cost of Work Performed), BCWP (Budgeted Cost of Work Performed), and BCWS (Budgeted Cost of Scheduled) values were obtained. The CV value obtained <0 in weeks 1 to 7 indicates that the costs incurred were greater than the plan, but in weeks 8 to 15 the CV value >0 means that in that week the costs incurred were less than the plan. Meanwhile, meaning the project is experiencing a delay from plan. The estimated of the completion budget requirement obtained from the ETC (Estimate to Compile) value is Rp. 3,345,105,521.28, while the estimated final total project cost obtained from the EAC (Estimate at Complete) value is Rp. 5,680,868,593.22.

Abstract

In project implementation, change orders frequently arise post-contract signing between the owner and contractor. These changes often stem from design modifications or budget adjustments by the owner. Contractor-initiated change orders result from disparities between design plans and bill of quantities, insufficient design details, impractical field conditions, complex design execution, and challenges in material mobilization. Poorly managed change orders can lead to increased costs, delays, and diminished contractor performance. To mitigate change orders, this study employs change order correlation analysis using original data, evaluating change order ratio (COR), change order ratio in addition (CORA), and change order ratio in subtraction (CORS). Analyzing six construction projects, the study concludes that the average Change Order Ratio Index (COR) is 26%, indicating a 26% change from the original contract value. The average Change Order Ratio in Addition (CORA) is 16%, signifying 16% of changes result from additional work. The average Change Order Ratio in Subtraction (CORS) is 10%, indicating 10% of changes stem from work being less than the original contract value.

Abstract

In constructing a toll road, the road structure will be carried out by constructing embankments on the road. However, in practice it often causes elevation differences between the two land surfaces, thereby increasing the risk of landslides. The objectives of the research are 1) Identifying the impact if Common Borrow Material (CBM) embankment work is replaced by rock embankment from excavation results, 2) Determine the value engineering process steps related to completing alternative design selection if there are differences between the actual Detailed Engineering Design in the field and 3) Determine the strategy and design optimization for volume differences which have implications for additional costs and project implementation time. The research uses a combination of quantitative and qualitative research methods. The data analysis technique is carried out using the Zero-one and Cost Analysis methods. The research results prove that 1) Implementation of the design review method for changes in common borrow material dumping work requires innovation to reduce cost elements and match performance and quality. 2) Solving problems using the design review method in the civil works construction phase where the Detail Engineering Design and actual field conditions have different stages of value engineering analysis. 3) Based on function analysis to optimize cost savings for work items using design review, a Preliminary Design according to DED Rp. 4,068,258,782,670 and Design after RE Rp. IDR 3,987,286,153,268 so the cost reduction after implementing the design review for the work of piling stones from stone excavation results is IDR 80,972,629,402.

Abstract

Project delays often serve as a catalyst for conflicts and disagreements between project owners and contractors, leading to significant financial implications. Such delays result in costly consequences for both parties involved. Contractors face the imposition of penalty fines as stipulated in the contractual agreement, alongside incurring overhead costs during the prolonged project duration. Conversely, owners experience a direct impact on their revenue streams due to delays in the operationalization of the facility. In the context of the construction of the Surabaya Open University Distance Learning Program Unit building phase II, the examination of cost and time performance becomes imperative. Employing the earned value method offers a comprehensive approach to project performance evaluation, involving a meticulous comparison of actual expenses and timelines with the initially anticipated costs. This analytical approach aids in understanding the project's progress and identifying areas where adjustments may be necessary to mitigate potential delays. The Earned Value Method (EVM) analysis of the Surabaya Open University Distance Learning Program Unit building phase II reveals a projected total cost of IDR 73,908,443,223.09 by the time the project reaches completion. This estimation provides stakeholders with valuable insights into the financial commitment required for the successful conclusion of the project. Additionally, the anticipated timeline for completion is estimated at 53 weeks, serving as a crucial parameter for project planning and management.

Abstract

Project completion delays have adverse consequences on a contractor's credibility and result in additional penalty costs, reducing potential profits. To mitigate these issues and optimize project outcomes, refining activity schedules and budgets is crucial. The Earned Value Method proves effective in monitoring and controlling project activities. In the case of the Kediri airport access road construction project, weeks 1 to 6 revealed a negative Cost Variance (CV), indicating higher-than-planned costs, while weeks 7 to 8 showed a positive CV, suggesting costs were lower than anticipated. Schedule Variance (SV) for the 1st week was unfavorable, indicating a delay, and SV>1 from weeks 2 to 8 signaled a project delay. The Estimate to Complete (ETC) is IDR 17,470,510,292.77, and the Estimate at Complete (EAC) is IDR 32,509,153,464.05. The Time Estimate (TE) forecasts project completion in 89 calendar days, five days beyond the contracted 84 days. Employing the Earned Value Method enhances project performance evaluation and decision-making to avoid delays and cost overruns.

Abstract

The construction project of the McD Pontianak building encountered significant challenges due to a tight schedule of 110 calendar days and unforeseen delays arising from the existing building's foundation. These delays led to a setback in the construction progress, prompting the need for strategic measures to accelerate the project and mitigate the delays amounting to 11.48%, equivalent to 12.63 days. The potential financial consequences of this delay were estimated at IDR 228,366,605. In order to expedite the construction process, the chosen acceleration method was the crashing method, involving an increase in overtime ranging from 1 to 4 working hours, in accordance with relevant laws and regulations. This required a comprehensive analysis encompassing normal cost, normal duration, critical path, productivity, crashing cost, and crashing duration calculations. Upon thorough examination, it was determined that the optimal solution to overcome the delays was to implement an additional 2 hours of overtime. However, this decision came with associated costs, resulting in a necessary expenditure of IDR 93,651,965 to achieve a crashing time of 18.30 days. Despite the increased financial commitment, this strategic approach was deemed essential to meet the project's original schedule and avoid potential penalties. The findings and conclusions drawn from this analysis provide valuable insights into effective project management and decision-making in the face of unexpected challenges in the construction industry.
