The general objective of the research is to find out the measured data of standard or SOP deviations with the implementation of OHS in the field and to find out the causes of the implementation of OHS as an influence on the number of occupational accidents that occur in construction projects. The research method uses descriptive and observational design, research data in the form of questionnaires as primary data and OHS plan reports as secondary data. As subjects in the study were 25 workers in the Villa Babakan Canggu building project. Based on the results of the analysis through the initial level internal audit with 64 criteria according to Government Regulation No. 50 of 2012 concerning the application of OHS, the assessment level of the application of OHS was 80.45 percent with the category of good application and the results of the quiz test stated that the workers agreed that the project implementers had prepared working conditions accordingly with OHS standard with a score of 1.75. Workers do their job with a natural work attitude with a score of 1.68.

Every construction project is always faced with the possibility of problems in the project. In reality, the implementation of construction projects always experiences obstacles that result in delays in the completion of work, so that the completion time of the work is not in accordance with the work plan that has been set. Delays that occur will cause losses for related parties, especially owners and contractors, because they are generally accompanied by conflicts, demands for time and costs, and deviations in the quality of project completion. Based on the thoughts and problems mentioned above, a research was conducted to determine the dominant factor causing delays in the execution time of work on the Denpasar Living World Mall Building Project which may be different from other projects and provide alternatives for handling the delay factor. This research was conducted at the Living World Mall Denpasar. Taking the research location based on consideration of the factor that has the most dominant influence on the delay in the implementation of the Living World Mall Development project based on the results of descriptive analysis is the Labor Factor (X2) with an RI value of 0.89.

Risk is the possibility of the occurrence of an event outside of which every activity that is likely to be detrimental is carried out by humans. In the Nangarasong Steel Frame construction project in Flores district, there is uncertainty which will create a risk that can encourage the project and can affect the potential for work accidents. Uncertainty factors can cause risk in an activity that has an impact on decreasing labor productivity, risk of cost, time, and damage to design or technology. To reduce these adverse impacts, a risk management system is needed, which includes analysis, analysis, and monitoring of risks that may occur. Risk management makes an integrated effort to manage the risk of work accidents by using the FMEA (Failure Mode And Effect Analysis) method. All construction projects that may experience accident risks are identified and analyzed for the severity with FMEA, from the results of which the causes and impacts of the work accident risks will be sought. After knowing and the impact of the risk of work accidents, the next action on the risk of work accidents that result.

Building Information Modeling (BIM) adalah suatu proses yang dimulai dengan menciptakan 3D model digital dan didalamnya berisi semua informasi bangunan tersebut, berfungsi sebagai sarana membuat perencanaan, perancangan, pelaksanaan pembangunan, serta pemeliharaan bangunan. Estimasi biaya menggunakan BIM memberikan kecepatan dan keakuratan perhitungan volume pekerjaan.  Pengaplikasian BIM menggunakan software salah satunya Tekla Structure. Tekla Structure merupakan software memungkinkan membuat model yang sangat constructable struktural 3D terlepas dari materi atau kompleksitas struktural. Berdasarkan kelebihan BIM maka cocok diaplikasikan pada proyek pembangunan pasar desa adat Pecatu. Pembangunan pasar desa adat Pecatu merupakan proyek pemerintah Kabupaten Badung. Pasar desa adat Pecatu memiliki fungsi sebagai tempat bertransaksi pedagang dan pembeli di desa adat Pecatu. Langkah-Langkah estimasi menggunakan BIM diawali membuat pemodelan struktur bangunan pasar desa adat Pecatu 3D. Pemodelan 3D dimulai dari pemodelan pondasi dilanjutkan dengan pemodelan sloof, kolom, balok, ring balok, dan atap baja dan kayu. Setelah pemodelan 3D selanjutnya dilakukan tahap estimasi menggunakan fasilitas menu quantity take off dari software Tekla Structure untuk mendapatkan volume masing-masing item struktur bangunan. Estimasi biaya dilakukan dengan cara mengkalikan volume item pekerjaan dengan harga satuan pekerjaan dengan fasilisitas software Microsoft Excel. Hasil dari estimasi biaya menggunakan BIM adalah Rp. 5.746.833.111,23 lebih rendah 1,88 % dari RAB existing.

The purpose of this study is to determine the dimensions and reinforcement of structure, cost, and schedule due to the transition structure of the building function. The structural transition of building functions is carried out in the earthquake area five with the classification of soft and hard soils. The building used as a research model is a 3-story residence on Nuansa Utama Selatan Street number 3, Jimbaran, Bali. The planning of this building will be converted into office buildings and shophouse on the 2nd and 3rd floors functioning as a warehouse in the earthquake area five in Bali with the classification of soft and hard soil that will be analyzed using SAP 2000 program so that the structural dimensions are used as a reference in the creation of costs, and schedule obtained using Microsoft Project program. The analysis of structure shows that the structure of a residential house on hard soil has the dimensions and reinforcement of the smallest structure. The ratio of structural reinforcement in the transition of structure functions from residential house to office on hard soil by 1.32% with the lowest structure cost ratio by 1.80% and schedule of the structure by 3.80%.
