Road Widening

In a construction project, there are several aspects that cause the project not to go according to plan. Cost and time are aspects that need to be considered to avoid losses incurred in a project. Jombang-ploso-legundi-gresik road project is one of the road widening projects carried out by PT. Mix Pro Indonesia. The project was carried out with the aim that access to (Surabaya-Mojokerto) or further trans Java toll road is quicker safe and smoother. This research aims to optimize the cost and time on the project using the Earned Value method. Calculations include the calculation of ACWP (Actual Cost of Work Performance), BCWS (Budgeted Cost Work Schedule), and BCWP (Budgeted Cost for Work Performed) using the Earned Value method. From these parameters, estimate aspects of cost and time. As well as project analysis of acceleration on a critical trajectory of work. The results of calculations in the 12th week obtained a BCWS value of Rp 1,216,677,846,400 BCWP = Rp 3,040,372,140,080, ACWP = Rp 3,678,560,000. CV value = -Rp 109,203,495.92, SV = Rp 895,646,816.82, CPI = 0.827, and for SPI = 2,499. From these results it can be seen that the CPI value < 1 which means that there are project expenditures that exceed the original plan. With the results, it can be used as a reference in the implementation of project activities.

The paper provides a thorough examination of the impact of COVID-19 on increasing the cost of the construction project. The pandemic of COVID-19 had disrupted the financial and operational of the construction industry. Many projects have been closed and suspended, and this situation has caused great uncertainty in the construction industry. Even though the Instruction of the Minister of Public Work No. 2/2020 issued March 27, 2020, stated that construction activities in Indonesia could continue work. However, it still believes COVID-19 can lead to poor project cost performance. The study used a literature review to explore the factors contributing to the increase in project cost. A case study in the hotel construction project is used to test the factors. The research found six factors have a frequency of occurrence for each cause of cost overrun, namely labor, material, implementation time, project financial aspects, estimated cost, and occupational health and safety. The case study’s two factors are not the cause of the cost overrun based on the interviewee’s answer: heavy equipment and overhead. This paper also explains the mechanism to address cost overrun continue in construction work.

This study aims to identify the most important factors that cause delay in road construction projects in Jordan, which results in cost and time overrun allocated for this type of engineering projects and cause critical problems for both the developer and the contractor. The gap between the cost at completion and that originally estimated, known as cost overrun, can be regarded as one of the most important parameters reflecting the success of projects. In the public sector, money spent on project change orders results in increased construction time which in return reduces the number and size of the projects that can be completed during any given fiscal year. To achieve this goal, the documents and the final reports for several sample projects implemented over the years 2000 to 2008 were analyzed. All the projects were administered by the same organization taken from Jordan Ministry of Rural and Public Works. The results of this study can assist highway officials in their design, planning, scheduling and projects completions so that necessary actions can be taken to control these overruns in future projects. The study showed that 19 factors might cause delays of road construction projects as defined through a detailed literature review. The analysis of the study indicated that the top causes affecting time and cost overrun in road construction projects in Jordan are Terrain and Weather conditions.

Environmental Impact Study

Roads are important infrastructure facilities that enable traffic accessibility, i.e. they improve the quality of transport communication between people, goods and innovations. The Podravina high-speed road project was designed with the aim of developing Podravina and Slavonia and enabling a better connection between them and the rest of Croatia. Road construction is a complex process that requires a location permit before construction begins. This paper is written with the aim of presenting in detail the process of obtaining a location permit, which is preceded by obligatory preliminary work. Its complexity depends on the type of a road, its purpose and characteristics of the area through which a planned road passes. The Podravina high-speed road is the largest infrastructure project in that part of Croatia and therefore detailed preliminary work is required. This paper describes some types of preliminary work which include geological, geomechanical and climatic tests. The paper presents a project justification study, an environmental impact study, an environmental impact study, a construction and a technical study as well as a spatial transport analysis. Based on the chosen Podravina high-speed road route, a general design was created by using a road design software program “Platea”.

One attempt to create a good transport system is the construction of new roads toll roads. A toll road construction soon to be implemented is AA segment a which is of  investment oriented and expected to give profits to the investors. According to the plan, the toll road is 40.5 km long development is divided into 4 sections. Data required to perform financial analysis is the cost of investment, operation and maintenance cost, traffic volume, and the toll rate plans. These data to find the values of the parameters used to calculate the financial analysis include the Net Present Value (NPV), Internal Rate of Return (IRR), Benefit Cost Ratio (BCR), and Payback Period (PP). The financial analysis will use two funding alternatives, alternative I using 100% equity, alternative II using 30% equity and 70%  loan. The purpose of this study is to determine the results of the financial analysis of the parameter values of highway construction project feasibility and determine the most influential factors after a sensitivity analysis has been made. Based on the financial analysis the investment cost results in IDR 3,827,698,222,645. The financial analysis NPV parameters alternative I results in IDR 661,439,934,962 and alternative II in IDR 230,334,925,350 which means they are feasible because both NPVs are greater than 0; both the IRR of 14.18% for alternative I and 13.02% for alternative II are greater than Minimum Attractive Rate Of Return (MARR) value of 12.42%; so, they are feasible; the value of BCR of alternative I is of 1.13 and alternative II is of 1.04; so, they are feasible because the value of BCR is greater than 1. While the PP of alternative I in the period of 12.1 years and alternative II in the period of 13.5 years. The sensitivity analysis of alternatives I and II result in  the most influential alternative—when construction period experiences ≥ 3 years backwards.Keywords: investment cost, financial analysis, sensitivity analysis.
