The Cost

A Change Order is a written and legal work order that changes the scope of the original contract, with compensation that has been agreed upon by the owner and the contractor. Changes can be in the form of adding or reducing the scope of work, changing materials, or changing schedules. Change Order causes the cost of contract items to swell, planning errors and negligence as well as changes in scope that can be reduced by sharpening planning results. The scope of research on road construction in Indonesia, especially in DKI Jakarta and Banten provinces. This study aims to determine the identification of change orders in road construction projects. Data obtained from real data on road construction projects from 2013-2018 on 16 road construction project packages in the form of road construction project addendum contracts. Based on the addendum contract, added work, less work, addition of new items and removal of work items are determined. The identification of change order risk is seen from three aspects, namely the addition and reduction of work items, the removal of items and the addition of new items and the wishes of the owner, thereby increasing the cost of the change order contract. This study found 732 changes in construction work items. Risk identification is obtained from the frequency of changes above 35% which is an intermediate frequency that tends to increase the occurrence of change orders. The results of risk identification were obtained for 31 construction work items, the highest percentage was for Thermoplastic Road Marking work, followed by 30 other construction work items. Keywords: risk identification; change orders; road construction projects  AbstrakChange Order adalah perintah kerja tertulis dan sah  yang mengubah lingkup kontrak semula, dengan kompensasi  yang sudah disetujui oleh pemilik dan  kontraktor.  Perubahan dapat berupa penambahan atau pengurangan lingkup pekerjaan, perubahan material, atau perubahan jadwal. Change Order menyebabkan biaya  item kontrak membengkak, kesalahan perencanaan dan kelalaian serta perubahan ruang lingkup yang dapat dikurangi dengan mempertajam hasil perencanaan.. Lingkup penelitian pada konstruksi jalan di Indonesia khususnya  provinsi DKI Jakarta dan Banten. Penelitian  bertujuan untuk  mengetahui  identifikasi change order proyek konstruksi jalan. Data didapat dari data riil proyek konstruksi jalan dari tahun 2013- 2018 pada 16 paket proyek konstruksi jalan berupa kontrak addendum proyek konstruksi jalan.

The Impact

In a construction project, changes during the construction period are common. This change can be in the form of an increase or decrease in volume and type of work, changes in work specifications, or changes in the schedule for implementation. Changes in projects are often known as change orders. Change orders must be approved by all parties in a project namely, contractors, owners, and consultants. Change orders are caused by several factors such as changes in design, delays in procurement of goods, differences in field conditions, and others. The impact of this change order is felt by all parties involved in a project, but the change order has a different impact on each party involved. This study aims to determine the biggest impact of change orders from the contractor. In the questionnaire submitted the impact of change order is divided into several variables namely, the cost of quality, time, organization, and others. From the responses of respondents regarding the impact of change orders on road construction projects, an analysis was performed with the calculation of the Relative Importance Index (RII), and the biggest impact was obtained. Before the data is processed with RII, the validity and reliability tests are performed first. The biggest impact of change orders caused by change orders is that change orders increase the budget for contractors, change orders increase overhead costs, increase project duration, cause project costs overruns, and change orders cause a decrease in project profits. AbstrakPada suatu proyek konstruksi, perubahan selama masa konstruksi merupakan hal yang umum terjadi. Perubahan ini bisa berupa penambahan atau pengurangan volume dan jenis pekerjaan, perubahan spesifikasi pekerjaan, maupun perubahan jadwal pelakasnaan. Perubahan dalam proyek sering dikenal change order. Change order harus disetujui oleh semua pihak yang ada dalam suatu proyek, yaitu kontraktor, pemilik, dan konsultan. Change order disebabkan oleh beberapa faktor seperti perubahan desain, keterlambatan pengadaan barang, perbedaan kondisi lapangan, dan lain-lain. Dampak dari change order ini dirasakan seluruh pihak yang terlibat dalam suatu proyek, namun change order menimbulkan dampak yang berbeda pada tiap pihak yang terlibat. Penelitian ini bertujuan untuk mengetahui dampak change order terbesar dari pihak kontraktor. Dalam kuesioner yang diajukan dampak change order dibagi menjadi beberapa variabel yaitu, biaya mutu, waktu, organisasi, dan lainnya. Dari hasil tanggapan responden mengenai dampak change order pada proyek konstruksi jalan, dilakukan analisis dengan perhitungan Relative Importance Index (RII), dan didapat dampak terbesar. Sebelum data diolah dengan RII dilakukan uji validitas dan uji reliabilitas terlebih dahulu. Dampak change order terbesar yang ditimbulkan oleh change order adalah change order menambah anggaran untuk kontraktor, change order meningkatkan biaya overhead, menambah durasi proyek, menyebabkan biaya proyek membengkak, dan change order menyebabkan penurunan keuntungan proyek.

The Cost

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.

Complexity is very high in construction project and constrained by money and time. Change orders are commonly required during the execution of construction projects. They may increase, omit or adjust tasks in the project. Change orders affect the performance of construction job because they disturb current jobs and affect their schedule. The motive behind this study is to outline a complete assessment on change orders impacts. A review on past studies was performed to capture change order factors that affect project performance. Literature review and interviews with the industry professionals were used to finalize the factors into 16 critical factors. A questionnaire was distributed to industry specialists to capture the effect of these 16 factors on project performance. Complete answers of 102 surveys were received. Analytic Hierarchy Process (AHP) and Relative Important Index (RII) were utilized to analyze the responses. This study differs from other past studies by studying change order impact factors on three different change order types namely additional, omission and substitutional works. The most important change orders impacts factors as per the analysis outcomes are increased project management efforts, increased project re-planning, loss of efficiency due to work interruption, increased reworks/demolition works and delay of payments. This paper would help construction professionals to recognize change order impacts and would assist them in taking proactive actions to limit these impacts.

Every construction project is always faced with the possibility of various occurrence kinds of risks. The higher the level of complexity of a project, the greater the level of risk that might happen to the project. Based on historical data from tunnel construction many problems and even failure of tunnel construction caused by various factors has been noted and it can have an impact on project delays. A risk management is expected to reduce the adverse impact of risks faced during construction work. Tunnel construction needs management handling with high risk, so it is necessary to identify risks that can minimize bad risks. A risk management is expected to reduce the adverse effects of risks faced in a construction work. It is necessary to perform risk identification to manage the risks that we will face. To successfully improve the performance of tunnel projects, we need to identify various risk factors in a project for efficient project fulfillment. The research method begins with an extensive literature review by reviewing at least 48 journal, journal papers, review articles to provide a list of the main risk factors which are also added to the expertise to achieve a list of final risk factors that contain all risks that may be encountered during road construction. This analysis involves the identification, classification of various risks involved in the construction of a tunnel construction project.

Change Order

The number of high rise building construction projects in Jabodetabek area continues to grow. The main reason is increasing population of the region, so that development in the vertical direction becomes a solution. There are three important criteria in every construction project, namely cost, quality, and time. These criteria must be agreed upon and regulated in the form of a contract. Based on prior research, change orders cannot be avoided in every construction project. Change order can give complex impact and able to harm related parties. To minimize and anticipate the occurrence of change orders, it is necessary to know the factors that can cause changes in a contract. The factors that have been determined from the results of the literature study are compiled into a questionnaire to find out the main causes of change orders. The questionnaire was distributed to owners, contractors and consultants in high rise building projects in Jabodetabek area. PLS-SEM is used as a method for analyzing data in this study with the help of the smartPLS 3.0 program. From the results of the analysis carried out, obtained two factors that have a significant influence on the change order, namely construction factors and administrative factors.  ABSTRAKJumlah proyek konstruksi gedung bertingkat di wilayah Jabodetabek terus bertumbuh. Alasan utama karena kondisi wilayah yang semakin padat, sehingga pengembangan pembangunan ke arah vertikal menjadi solusi. Terdapat tiga kriteria penting yang menjadi fokus dalam setiap proyek konstruksi, yaitu biaya, mutu, dan waktu. Kriteria-kriteria tersebut harus disepakati dan diatur oleh pihak-pihak yang terlibat sesuai dengan ketentuan peraturan yang berlaku dalam bentuk kontrak. Berdasarkan penelitian terdahulu, perubahan atau change order merupakan hal yang umum dan tidak dapat dihindari dalam setiap proyek konstruksi. Change order memberikan dampak yang kompleks, sehingga sangat berpengaruh terhadap kinerja suatu proyek konstruksi dan dapat merugikan pihak-pihak yang terlibat di dalamnya. Untuk meminimalisir serta mengantisipasi terjadinya change order, maka perlu untuk mengetahui faktor-faktor yang dapat menyebabkan perubahan dalam suatu kontrak pada proyek konstruksi gedung bertingkat. Faktor-faktor yang sudah ditentukan dari hasil studi literatur disusun menjadi sebuah kuesioner untuk mengetahui penyebab utama dari change order. Penyebaran kuesioner tersebut dilakukan terhadap owner, kontraktor, dan konsultan pada proyek gedung bertingkat di wilayah Jabodetabek. PLS-SEM digunakan sebagai metode untuk menganalisis data pada penelitian ini dengan bantuan program smartPLS 3.0. Dari hasil analisis yang dilakukan, didapat dua faktor yang memiliki nilai pengaruh signifikan terhadap change order, yaitu faktor konstruksi dan faktor administrasi.

The Earned Value Method allows the prediction of future values of the total cost and duration of the construction project realization, and also it allows the early detection of the collisions between the schedule and the construction project budget. It is more often indicated its usefulness for monitoring and controlling the construction work progress in the time and cost formulation. It is used, in the indirect way, to control the risk in terms of the cost overruns of the construction project realization and in case of the failure to meet the deadline for completion of the construction project. The authors’ goal was not only to indicate the advantages of the method (widely discussed in the literature) but also to indicate some inaccuracies in the application of the Earned Value Method, which may affect the costs forecasting and the date of completion of the construction project. The conclusions are based on the analysis of several construction project realizations.

Introduction: Change orders in construction are considered to be one of the greatest controversial problems that must be handled and also considered to be difficult for project management to reasonably resolve as any variation leads to claims. Any construction contract is agreed under the concept of “good faith,” which include that the parties will have to trust each other in order to work on agreeing on a contract and that contract is considered to be reasonable when there is no purpose of taking benefit of the parties throughout the contract life. However, as soon as the contract wants to be changed by generating a change order, the parties behavior changes in relation to the initial “good faith” environment Objective: The aim of the paper is to find the causes of the change order and its effect on the projects and then analyze the causes using data mining techniques. Methods: The methodology of the paper includes the following steps. Several factors that lead to change orders were gathered from the literature review. A questionnaire was formed and then distributed to the managers, owners, contractors and engineers. A review of the project's documents was conducted to find the number of change orders in the project and analysis of the causes of the change orders was done using data mining techniques. Results and Conclusion: The change orders have a harmful impact on the cost and it must be minimized, the change order was analyzed using Adda Boost technique and the accuracy was about 95 which is considered a very good result.

The implementation of the construction project caused miscommunication, this made the contract became a reference during implementation. In the implementation of construction projects, there are often changes that not according to contract, for example: work volume changes, specifications changes, type or method of work changes, schedules changes , design changes, and others. These changes are commonly known as change orders. There are several things that cause a change order, for example: incompletable contract, design does not fit in the field, unsupportive weather, and others. This research is to determine the effect of change order in the aspects of cost, quality, and time in multi-storey building construction projects. Researchers used data from the responses of respondents consisting of contractors, consultants, and owners. The questionnaire made proposes several aspects of change orders and their effects on cost, quality, and time. Analysis of research data was carried out with the help of the SmartPLS 3.0 application program. The influence of change orders on costs is the lack of costs due to the addition of work items, while on quality is the quality decrease due to additional work volume, and on time is the delay in project completion due to changes in completed work.ABSTRAKPelaksanaan proyek konstruksi menyebabkan terjadi perbedaan pendapat yang disebabkan oleh pihak yang terlibat, hal ini membuat kontrak menjadi sangat penting dan menjadi acuan selama pelaksanaan. Pada pelaksanaan proyek konstruksi sering terjadi perubahan-perubahan yang akhirnya tidak sesuai dengan kontrak sebelumnya contohnya seperti: perubahan volume pekerjaan, perubahan spesifikasi, perubahan jenis atau metode pekerjaan, perubahan jadwal, perubahan design, dan lain-lain. Perubahan ini umum sekali terjadi dalam proyek konstruksi dan lebih sering dikenal sebagai change order.  Ada beberapa hal yang menyebabkan perlunya dilakukan change order, misalnya: kontrak yang dibuat tidak lengkap, design yang ada tidak sesuai dengan kondisi lapangan, cuaca yang tidak mendukung, dan lain-lain. Penelitian ini dilakukan untuk mengetahui besar pengaruh change order dalam aspek biaya, mutu, dan waktu dalam proyek konstruksi gedung bertingkat. Peneliti menggunakan data dari hasil tanggapan responden yang terdiri dari kontraktor, konsultan, dan pemilik. Kuesioner yang dibuat mengajukan beberapa aspek mengenai change order serta pengaruhnya terhadap biaya, mutu, dan waktu. Analisis data penelitian dilakukan dengan bantuan program aplikasi SmartPLS 3.0. Pengaruh change order terhadap biaya adalah kurangnya biaya akibat penambahan item pekerjaan, sedangkan terhadap mutu adalah menurunnya kualitas bangunan akibat penambahan volume pekerjaan, dan terhadap waktu adalah terjadinya keterlambatan penyelesaian proyek akibat perubahan pekerjaan yang telah selesai.
