Di dalam proses pelaksanaan proyek diperlukan suatu sistem untuk manajemen biaya dan manajemen waktu agar dalam pelaksanaannya, proyek tersebut dapat diselesaikan tepatwaktu, tepat mutu dan tepat biaya. Tujuan penelitian ini adalah untuk menghitung perkiraan (forecasting) besarnya biaya dan waktu yang diperlukan dalam penyelesaian proyek berdasarkan tinjauan pada suatu periode tertentu. Data diperoleh dari pihak kontraktor yang mengerjakan proyek tersebut yaitu jadwal pelaksanaan berupa kurva-s, data rencana anggaran biaya pekerjaan (RAB), laporan harian, mingguan dan bulanan proyek. Hasil analisis didapatkan bahwa pada tinjauan minggu ke-10 progres pekerjaan yang diperoleh menunjukkan besarnya biaya yang dibutuhkan untuk penyelesaian sisa pekerjaan sebesar Rp. 198.387.153,40 dan perkiraan sisa waktu penyelesaian pekerjaan akan terlambat 1 (satu) hari kalender dari waktu yang direncanakan dimana nilai ETS= 20,793 hari ∞ 21 hari dari sisa waktu 20 hari dalam jadwal rencana. Berdasarkan analisis disimpulkan bahwa kinerja biaya proyek cukup baik dengan cost performance index (CPI) sebesar 1,186 > 1 namun kinerja waktu proyek cenderung terlambat dengan schedule performance index (SPI) sebesar 0,962 < 1. Hasil ini dapat menjadi masukan bagi pihak kontraktor untuk melakukan tindakan-tindakan pengendalian untuk memacu pekerjaan agar tujuan pekerjaan tepat waktu dan tepat biaya dapat tercapai.

AbstractThe intent of this article is to explore a mathematically sound method to graphically monitor schedule performance index (SPI) such that it enables the project manager to take objective data based decisions regarding the progress of the project schedule. The article aims to leverage the theory and application of control charts, specifically the U chart and Laney U chart and test its applicability to earned value management by trending schedule performance index on a time series chart. Off the shelf software, MinitabTM was used to generate the control charts based on earned value and planned value. While this paper proves that the Laney U chart, with correct interpretation, acts as an effective trigger-based tool for schedule risk management, it also generates further avenues for research into similar use of control charts for cost performance and other quality indices.

Machine Learning Regression Techniques (MLRT) as a shrewd method can be utilized in this study being exceptionally fruitful in demonstrating non-linear and the interrelationships among them in problems of construction projects such as the earned value indexes for tall buildings projects in Republic of Iraq. Three forecasting models were developed to foresee Schedule Performance Index (SPI) as first model, Cost Performance Index (CPI) as a second model, and the third model is To Complete Cost Performance Indicator (TCPI) in Bismayah New City was chosen as a case study. The methodology is mainly impacted by the deciding various components (variables) which impact on the earned value analysis, six free factors (X1: BAC, Budget at Completion; X2: AC, Actual Cost; X3: A%, Actual Percentage; X4: EV, Earned Value; X5: P%, Planning Percentage, and X6: PV, Planning Value) were self-assertively assigned and agreeably depicted for per tall buildings projects. It was found that the MLRT showed good results of estimation in terms of correlation coeffi cient (R) generated by MLR models for SPI and CPI and TCPI where the R were 85.5%, 89.2%, and 86.3% respectively. At long last, a result tends to be presumed that these models show a brilliant concurrence with the genuine estimations.

Schedule Performance

As a concept of project control that provides a quantitative measure of schedule and cost information, earned value (EV) can evaluate work progress by identifying potential delays and cost overruns. When EV is used as a construction control technique, the schedule performance index (SPI) and the cost performance index (CPI) are the core factors in the EV system. The standard is only 1, i.e., 1.0 above or below. Though the two indices have important roles in the EV system, those indices do always show the project status exactly; for example, when planned value (PV), EV, and actual cost (AC) are not collected in a timely manner. Additionally, there is no guideline on how each value in SPI and CPI is understood or how to read the hidden meaning behind the construction status. Therefore, this study first speculates about the meaning of the two indices, then suggests a practical application, and finally shows the framework where the two indices apply to various types of construction.

Schedule Execution

The traditional approach of managing project performance is with the use of Earned Value Management. There is a recent trend towards the expansion of traditional Earned Value Management practices to include the concept of Earned Schedule. Whereas Earned Value provides insight as to how the project is trending in relation to the plan by assessing cost and schedule variances, Earned Schedule focuses on the time element of schedule performance throughout the project execution phase. Earned Value, although very effective at providing visibility to cost performance, is not as transparent when it comes to schedule performance over time. Case in point, at completion, irrespective as to how work progressed on the schedule (ahead or behind plan) at completion, the schedule performance index will always be 1.0. Earned Schedule overcomes this drawback, providing useful tools to report on schedule performance, and providing visibility to the project state from which to base informed decisions. To perform the analysis, Earned Schedule analysis incorporates detail from the baseline and forecast schedules as well as the integrated project management cost report (earned versus planned). In addition to looking at Earned Schedule metrics, other key metrics are factored into this approach to assess overall schedule performance. Key metrics derived from the schedule and highlighted in this approach include: • Critical Path Length Index (CPLI) • Baseline Execution Index (BEI) • Total Float Consumption Index (TFCI) • To Complete Schedule Performance Index (TSPI) • Predicted Forecast Finish Date (PFFD) • Schedule Performance Index (time) (SPIt) • Independent Estimate At Complete (time) (IEACt) The intent of these metrics is to identify trends and assist in predicting project outcomes based on past performance. Since this approach is highly dependent on the schedule data, the more compliant a schedule is to industry best practices the better the quality of the results. The metrics are negatively impacted by recent re-baselining as this causes us to lose historical performance detail. Frequent analysis of the schedule execution reporting metrics defined above provides transparency of project performance and brings visibility to early risk triggers in support of a proactive approach to project execution monitoring and control. This paper will present a case study demonstrating how additional transparency through this approach highlighted a potential schedule risk. This increased visibility allowed the project team to reprioritize and implement proactive corrective actions to mitigate any potential impact to the project In Service Date (ISD).

Construction projects are risky in both physical implementation and management. The characteristics of the risk reinforce the necessity of efficient management to increase the chances of success without commitment to its goals. This study explores the correlation of delay and the schedule performance index (SPI) to evaluate the risk of a construction project completed with time overruns. The hypothesis that the SPI of projects with a delay is distinct from those projects without a delay is assumed. A database with 19 elements was used to test this hypothesis and to calculate limit values to the SPI. Therefore, the risk of delay will be small when the observed SPI is greater than the superior limit and large when the SPI is below the inferior limit. The simplicity involved in the calculation of these values showed an advantage in comparison with other methods of risk evaluation. Another strong point observed is that any company can determine the value of risk by considering its own history and support decisions like doing corrective actions.

In the recent years, owners and construction management companies have shown an increasingly more interest in adopting approaches that result in enhanced quality and less risks, conflicts, and wastes on their projects despite potentially higher initial cost. Implementing advanced technology trends and incorporating more integrated methods of delivering projects have proven to be highly value-adding and forward-thinking approaches. The objective of this research was to evaluate the effectiveness of and the synergy between three of such trending concepts in the construction industry, namely, integrated project delivery (IPD), lean principles, and building information modeling (BIM) in terms of cost and schedule performance measures. Data analysis was conducted on 72 vertical projects through interviews and study of the published articles, reports, and case studies. Qualitative analysis was performed through grounded theory while quantitative analysis was implemented using univariate and multivariate analysis of variance tests on schedule performance and cost performance. Results of the grounded theory analysis summarize six crucial characteristics required for an effective coordination between IPD, lean construction, and BIM. Statistical analysis on different combination of these three components revealed considerable effectiveness in terms of schedule performance while the effect on cost performance was not as much significant. This study contributes to the body of knowledge and practice in the field of construction by demonstrating the cost and schedule benefits realized through the use of IPD, lean construction, and BIM and identifying their collective conceptual advantages.

ABSTRAK Penelitian ini merupakan studi kasus pemasangan beton pada PT. Trans Pacific Petrochemical Indotama Tuban. Penelitian ini dilatarbelakangi oleh adanya permasalahan yang dihadapi oleh perusahaan tersebut karena lokasinya berada di tepi laut terhadap adanya keropos tanah yang bisa mengancam keberadaan akses dan peralatan vital perusahaan. Dari hasil investigasi penyebab adanya keropos tanah tersebut disebabkan karena keberadaan penangkis ombak tidak mampu lagi bekerja dengan performa yang diharapkan karena mengalami korosif dan berkarat sehingga tidak mampu mencegah adanya erosi dan abrasi ombak laut. Berdasarkan hasil investigasi tersebut pula, perusahaan mengambil langkah untuk membuat penangkis ombak yang baru terbuat dari komponen beton dengan mempertimbangkan umur ekonomis, efektivitas kerja dan biaya pemeliharaan. Dalam rangka untuk mengetahui apakah upaya teknik pengendalian waktu pelaksanaan proyek dilakukan secara efektif pada proyek beton penangkis ombak, maka diperlukan analisa penerapan manajemen waktu pada proyek tersebut. Teknik pengendalian pada proyek yang diteliti dilakukan dengan menggunakan metode nilai hasil (earned value) yang merupakan upaya pengendalian terpadu pelaksanaan waktu proyek dengan aplikasi Kurva S. Berdasarkan analisa penerapan manajemen waktu pada proyek yang diteliti, didapatkan informasi waktu pelaksanaan proyek pada minggu ke-1, ke-2, ke-3 dan minggu ke-7 berjalan dengan lebih lambat dari jadwal yang direncanakan; kemudian pada minggu ke-4, ke-5, ke-6, ke-8 dan minggu ke-9 berjalan dengan lebih cepat dari jadwal yang direncanakan; dan akhirnya pada minggu ke-10 pelaksanaan proyek mencapai penyelesaian sesuai dengan jadwal yang direncanakan. Berdasarkan atas analisa kinerja jadwal dengan menggunakan metode nilai hasil (earned value method) pada pelaksanaan proyek beton penangkis ombak, didapatkan hasil perhitungan varian jadwal (schedule variance) SV = 0 dan indek kinerja jadwal (schedule performance index) SPI =1. Dengan demikian, hasil analisa pelaksanaan proyek yang diteliti secara meyakinkan menunjukkan terjadinya jadwal pelaksanaan proyek sesuai dengan jadwal yang telah direncanakan (on schedule).
