ANALISA METODE CRITICAL PATH METHOD PADA PROYEK PEMBANGUNAN ELYON CHRISTIAN SCHOOL SURABAYA
No full textDalam setiap pelaksanaan proyek konstruksi terdapat tiga hal penting yang menjadi fokus utama yaitu biaya, mutu dan waktu. Waktu penyelesaian proyek yang direncanakan dan tersusun dengan baik akan menentukan keberhasilan setiap proyek. Didalam perencanaan waktu penyelesaian proyek hal yang perlu diperhatikan adalah item-item pekerjaan yang melewati jalur kritis, hal ini dikarenakan item pekerjaan yang melewati jalur kritis sangat berpengaruh terhadap waktu penyelesaian proyek yang mana apabila item pekerjaan melewati jalur kritis mengalami keterlambatan maka waktu penyelesaian proyek juga akan ikut terlambat. Penelitian ini menggunakan metode Critical Path Method berupa diagram jaringan kerja dengan menggunakan data pada proyek Elyon Christian School Surabaya. Hasil yang diperoleh pada penelitian ini adalah terdapat 9 item pekerjaan yang berada di jalur kritis yaitu dengan kode pekerjaan B1-C1-D1-E1-F1-G1-H1-I1-I2.
In every construction project implementation there are three important things that become the main focus, cost, quality and time. The planned and well-structured project completion time will determine the success of each project. In the project completion time planning things to note are the work items that pass through the critical path, this is because the work items that pass through the critical path are very influential on the project completion time which if the work items pass through the critical path are delayed then the project completion time will also be late. This study uses the Critical Path Method in the form of a network diagram using data on the Elyon Christian School Surabaya project. The results obtained in this study are 9 work items that are in the critical path, the work code B1-C1-D1-E1-F1-G1-H1-I1-I2.

Cost Contingency Strategies in Building Construction: Evaluating Project Risk Influence
No full textContingency costs are an important part of construction to achieve successful project management. In determining contingency costs, practitioners have used a very subjective approach. This study discussed the determination of the contingency cost of high-rise buildings in six research object projects, based on the results of risk evaluation. The risk evaluation used in this paper is based on the risks in the construction phase. The method used to know the relationship between risk and contingency costs is simple linear regression with tools. The results of this study indicate that the greater the level of risk, the greater the contingency costs incurred by the project. the risk level contributed 71.6% to the contingency cost, while the rest was influenced by other factors. The equation formed is, that if the risk increases by 1 unit, the total contingency cost will increase by 0.0916 units.Contingency costs are an important part of construction to achieve successful project management.

Mempercepat Waktu Pelaksanaan Proyek Pembangunan Jalur Ganda Kereta Api Antara Mojokerto-Sepanjang Melalui Penjadwalan Line of Balance
No full textIn construction management, project scheduling is an important thing to note. The project schedule is a means of determining proper duration, controlling implementation progress, and allocating resources efficiently. Improper scheduling will have an impact on project delays. the project for the construction of a double track railway across the south of Java between Mojokerto-Sepanjang is planned to be completed in 60 weeks with overlapping activities due to changes in activities. This double track rail project is an ongoing project. This research aims to find out the project implementation time using the Line of Balance. The development project has a length of 3011.23 m. the Line of Balance method is carried out by determining the dependency logic, preparing a Line Of Balance schedule, drawing a Line Of Balance graph, and determining the production speed. The results of the study show that the line of balance schedule in the existing conditions has lines of intersection between jobs. The intersection indicates that there is overlapping work. For this reason, improvements are made by changing the dependency logic from work that was originally parallel to not parallel. The results of improvements made by reducing the duration per work cycle by 1 week revealed that the duration of the project could be accelerated to 38 weeks. So that the scheduling can be used to speed up the time of implementation of project activities

STUDI PERENCANAAN GEDUNG TINGKAT TINGGI DAN GEDUNG TINGKAT RENDAH DENGAN MENGGUNAKAN BRESING KONSENTRIK
No full textAbstrakKonstruksi Bangunan yang menggunakan material baja sangat cocok untuk daerah yang rawan gempa karena sifat baja yang daktail dan Letak geografis Indonesia berada di pertemuan lempeng benua dan lempeng samudera, menjadi salah satu penyebab frekuensi gempa di Indonesia tinggi sehingga permukaan tanah dan bangunan diatas tanah ikut bergetar dan timbul gaya-gaya pada struktur bangunan akibat dari adanya kecendrungan massa bangunan untuk bertahan dari gerakan, sehingga gempa bumi mempunyai kecendrungan menimbulkan gaya lateral pada struktur bangunan yang menyebabkan adanya suatu simpangan horizontal. Adanya suatu simpangan horizontal ini tidak boleh melebihi batas yang ada pada SNI 1726 2019 tentang besarnya simpangan ijin.Terlepas dari frekuensi gempa yang sering terjadi di Indonesia, tentu perlu untuk tetap membangun guna memenuhi kebutuhan akan gedung-gedung baik gedung tingkat tinggi maupun gedung tingkat rendah yang bisa tahan terhadap gempa. Salah satu yang bisa dilakukan sehingga bangunan gedung yang ada baik tingkat tinggi maupun tingkat rendah aman terhadap gempa bumi yaitu dengan penambahan bresing tipe konsentrik pada suatu struktur bangunan. Sistem ini mempunyai sifat yang daktail tetapi juga bersifat kaku, dimana dalam penelitian ini bresing diletakkan secara konsentris terhadap hubungan balok-kolom.Penelitian ini bertujuan untuk mengetahui perbandingan simpangan gedung bertingkat Tinggi dan bertingkat rendah yang menggunakan bresing konsentrik. Berdasarkan hasil simpangan yang diperoleh simpangan pada gedung bertingkat rendah lebih kecil dibanding bertingkat tinggi. Simpangan yang diperoleh dari gedung bertingkat rendah yaitu Simpangan Konsentrik arah X, Y rerata berturut-turut 13,53 mm dan 13,11 mm. Sedangkan Simpangan yang diperoleh dari gedung bertingkat tinggi yaitu Simpangan Konsentrik arah X, Y rerata berturut-turut 15,47 mm dan 16,87 mm.Abstract Construction of buildings using steel materials is very suitable for earthquake-prone areas because of the ductile nature of steel and Indonesia's geographical location is at the confluence of the continental plate and oceanic plate, which is one of the causes of the high frequency of earthquakes in Indonesia so that the ground surface and buildings on the ground also vibrate and Forces arise in the building structure as a result of the tendency of the building mass to withstand movement, so that earthquakes have a tendency to cause lateral forces on the building structure which cause a horizontal displacement. The existence of this horizontal deviation must not exceed the limit in SNI 1726 2019 regarding the amount of permit displacemenet.Regardless of the frequency of earthquakes that often occur in Indonesia, of course it is necessary to continue to build to meet the need for buildings, both high-rise buildings and low-rise buildings that can withstand earthquakes. One thing that can be done so that the existing high-level and low-level buildings are safe against earthquakes, namely by adding concentric type braces to a building structure. This system has a ductile but also rigid nature, where in this study the braces are placed concentrically to the beam-column relationship.This study aims to determine the ratio of the displacement of high-rise and low-rise buildings using concentric braces. Based on the displacement results obtained, the displacement in low-rise buildings is smaller than in high-rise buildings. The displacements obtained from low-rise buildings are Concentric displacements in the X, Y directions with an average of 13.53 mm and 13.11 mm, respectively. Meanwhile, the d displacements obtained from high-rise buildings are Concentric displacements in the X, Y directions, with an average of 15.47 mm and 16.87 mm, respectively
