Pesatnya perkembangan infrastuktur transportasi khususnya jalan raya memainkan peranan penting dalam menghasilkan material sisa baik itu material sisa kontruksi maupun akibat pembongkaran, terutama pada pekerjaan tanah, pondasi base, aspal dan rigid. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang dapat menyebabkan terjadinya material sisa pada pekerjaan kontruksi jalan. Metode penelitian ini dilakukan melalui studi literature dan wawancara. Hasil penelitian menunjukanFaktor yang menyebabkan terjadinya material sisa antar lain Proses pengiriman material, adanya perubahan desain (redesign), adanya perubahan pekerjaan oleh owner (change order), adanya pekerjaan yang diulang (rework), kualitas material, keahlian/keterampilan SDM (skil)l, cara penyimpanan material di lokasi proyek, pengawasan, metode kerja, miskomunikasi (salah pengertian), informasi kurang jelas, kondisi lapangan. Pengelolaan Material sisa kontruksi dapat dilakukan dengan menerapkan langkah-langkah reduce, reuse, recycle, maupun salvage terhadap material sisa itu sendiri.

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.

It is vital to investigate the system dynamics (SD) between the change orders and labor productivity to identify the causes of the productivity loss of the construction projects. Most productivity loss studies were financed from the contractor’s part and rely on the contractor’s data. This research highlighted the problem of productivity loss resulting from issuance of a change order by utilizing a previously developed SD model. It conducted a sensitivity analysis to evaluate the impact of overtime, overmanning, temperature and learning on the behavior of the SD model quantifying change orders' impact on labor productivity. Based on the results, SD provides more reliable results comparing with the measured mile analysis (MMA) approach for the compensation request, considering the leading factors affecting the productivity loss other than the change order. The model developed in this study can accept or reject the responsibility of a change order for occurrence of productivity loss.

PurposeThe purpose of the paper is to develop a method to integrate the schedule-based analysis with a productivity-based analysis to prove and support the result of the damages calculation.Design/methodology/approachIn this paper, a “cost and schedule impact integration” (CSI2) model is proposed to objectively show and estimate lost productivity due to changes in construction projects.FindingsA schedule-based analysis to include separate tracking of change order costs can be used to predict productivity due to the delay and disruption; changes in construction projects almost always result in delay and disruption. However, the schedule-based analysis needs to be integrated with a productivity-based analysis to prove and support the result of the damages calculation.Practical implicationsThe results of this study expand upon construction practices for proving and quantifying lost productivity due to changes in construction projects.Originality/valueThe contribution of the paper is summarized as the introduction of a “schedule impact analysis” into a “cost impact analysis” technique to assess the damages, as well as to demonstrate the labor productivity impact due to delay and disruption in construction projects.

Purpose – With the increase in the cases of construction claims in Nigeria, many projects have remained uncompleted, while many of those completed receive poor client satisfaction. The purpose of this paper is to investigate how construction claims are managed. Design/methodology/approach – In total, 58 claim factors were identified and addressed to construction professionals through survey to indicate the extent at which the factors contributed to claims. A case study was conducted to illustrate claim management. Findings – In total, 37 factors were the major source of claims. Late payment, delayed approval of change order and delay cost were the extremely influential while the least were storage charges, loss of productivity, and costs of preparing claims. Evidences revealed that all stakeholders should play active roles to deliver “claim free” projects. Practical implications – The findings will be useful to practitioners in the effort to improve project delivery by providing some guidance on claim minimization. It is hoped that this study will encourage academics to conduct more research on this issue. Originality/value – There is no known conclusive empirical study on construction claim factors in Nigeria. In light of this, the findings offer greater opportunities for claim minimization/avoidance.
