Abstract

Departing from academic anxiety that the construction industry in Indonesia has made rapid progress with the adoption of computing technology and methods in recent years. Increasing infrastructure development encourages construction actors to effectively and efficiently improve project quality. However, the role of the quantity surveyor becomes crucial in facing challenges such as manual quantity picking which is prone to errors and cost estimation that is difficult to do based on rough schematic design. In the context of traditional construction projects, quantity lists are arranged based on 2D drawings, but the use of 3D models has diminished since the adoption of BIM. Sketchup, as a 3D modeling software, and its extension Quantifier Pro provide a solution by combining 3D models to produce accurate quantity takeoff calculations on the Bill of Quantity. This research aims to develop methods to improve the quantity accuracy of elements of an incomplete or incorrect Sketchup model, in the hope of reducing modeling time, improving quantity retrieval performance, and making Sketchup-based cost estimation more effective and efficient in the context of construction. This research method involves 3D modeling using the Sketchup Pro application, using secondary data in the form of Detailed Engineering Design (DED) working drawings. Volume calculation in the Bill of Quantity is done with the help of Sketchup Pro software. The research location is in the Mullberry Cluster residential project, Bekasi City, West Java. The house building in this project was chosen as an object of comparison between conventional calculation methods and calculation methods using Sketchup Pro software. The main focus is to overcome the challenges of manual quantity picking and cost estimation from rough schematic design, emphasizing the crucial role of quantity surveyors. The results showed that the use of 3D models in Sketchup can increase the accuracy of cost estimation and reduce modeling time. The conclusion of the study confirms that Sketchup as an effective alternative solution in increasing efficiency and accuracy in the construction process, especially in the context of taking the quantity of architectural work elements, contributes positively to the development of more sophisticated cost estimation methods in the Indonesian construction industry.

Abstract

Kegiatan konstruksi memiliki peran penting dalam pertumbuhan ekonomi dan sosial suatu negara, karena dapat menciptakan lapangan pekerjaan dan berdampak positif pada industri terkait, seperti industri bahan bangunan dan jasa konstruksi. Namun kegiatan konstruksi juga membawa potensi risiko bagi pekerja dan pihak yang terlibat didalamnya. Oleh sebab itu, perusahaan dalam sektor industri konstruksi perlu memikiran solusi untuk dapat menghadapi permasalahan mengenai Keselamatan dan Kesehatan Kerja (K3), sehingga pada proses pengerjaan konstruksi dapat meminimalisasikan risiko terjadinya kecelakaan kerja. Penelitian ini bertujuan untuk menganalisis penerapan K3 sebagai pengendalian terhadap kinerja pada proyek konstruksi pembangunan bangunan landed house. Metode pengumpulan data dilakukan melalui pengamatan dan penggunaan kuesioner. Analisis data dilakukan dengan menggunakan analisis regresi linear berganda, hipotesis deskriptif, korelasi ganda, serta sumbangan relatif. Berdasarkan analisis regresi linear berganda diperoleh bahwa faktor Pengetahuan Pekerja, Manajemen K3, dan Pelaksanaan K3 berpengaruh terhadap Penerapan K3. Hasil dari korelasi ganda menunjukkan adanya korelasi yang sangat kuat antara faktor keberhasilan dengan penerapan K3. Faktor yang memiliki tingkat keberhasilan utama dengan nilai 65,36% adalah faktor Pelaksanaan K3, dimana faktor Pelaksanaan K3 didukung oleh tiga indikator utama yaitu faktor kesadaran pekerja akan pentingnya penggunaan alat pelindung diri pada lokasi konstruksi, faktor perencanaan dan prosedur keselamatan dan kesehatan kerja yang telah dibuat dengan mempertimbangkan identifikasi bahaya dan risiko, dan faktor pengetahuan pekerja mengenai alat pelindung diri. Dari hasil analisis yang dilakukan, penerapan K3 pada proyek konstruksi bangunan landed house Summarecon Serpong telah diterapkan dan sudah tergolong baik.

Abstract

Construction projects have become increasingly complicated and challenging to manage in recent years, especially in analyzing the quantity and cost estimation of construction work to get accurate results and overrun costs. The interdependence among different work items involved, such as architects, civil and electrical works, is one of the fundamental reasons. Besides that, the differences in standards used in analyzing the quantity and unit cost per work item made it more complicated. This study analyzed the existing modeling based on the measurement rules and unit cost standards to analyze the problem which has been explained above. Understanding the items was considered when examining the walls quantity to avoid missing information. In addition, measurement rules standards are utilized to calculate QTO, including NRM 2 standards from the UK and SMPI standards from Indonesia, to calculate the cost based on Indonesia standard SNI-AHSP. Furthermore, using visual programming Dynamo to analyze the quantity of wall works based on the required data, extract the data/information needed to calculate the cost based on unit cost standard, and check if the walls intersect with other elements to avoid excess quantity. Finally, using BIM technology based on standard measurement rules and overlapping element analysis to calculate the quantity and cost produced accurate quantity results and obtained the maximum cost detail per work item. Moreover, generate the information about the analysis results by utilizing the intelligent module to present the required information of the wall works, which improves the inadequacy of BIM. Indeed, it could save more time than calculating them manually and reduce human errors.
