Pondasi merupakan bagian penting dari suatu bangunan sipil, pondasi sebagai dasar penahan beban terdasar dari suatu konstruksi. Pondasi bertugas meletakkan bangunan dan meneruskan beban bangunan atas ke dasar tanah yang cukup kuat mendukungnya. Tujuan dari penelitian ini untuk menghitung daya dukung dan penurunan tiang bor, dimana kapasitas daya dukung pondasi dihitung berdasarkan data SPT dengan menggunakan 2 Metode yaitu Metode Meyerhoff dan Metode Reese & Wright. Dari hasil Analisa dan perhitungan daya dukung tiang kedalaman 18 m, diameter d1 = 0,4m dan diameter d2 = 0,6m. Berdasarkan Metode Meyerhoff, daya dukung tiang tunggal (Qull) sebesar Qu1 = 902,674 ton dan Qu2 = 466,6 ton, sedangkan menggunakan Metode Reese & Wright daya dukung tiang tunggal (Qull) sebesar Qu1 = 474,884 ton dan Qu2 = 296,107 ton. Dari analisa data Shop Drawing dan As Built Drawing  dan perhitungan ulang beban aksial menggunakan Etabs 19, cek aman beban aksial yang di pikul oleh bore pile dengan Metode Meyerhoff maupun Metode Reese & Wright setelah dilakukan perbandingan dengan daya dukung izin tiap kelompok, seluruh pondasi tiang bor  mampu menahan beban yang bekerja diatasnya, sehingga pondasi dikategorikan aman (Qall > Pp). Perbandingan daya dukung ijin tiang sebesar 1:0,639. Penurunan pondasi yang terjadi pada setiap tiang dikatagorikan aman karena penurunan tidak lebih besar dari penurunan maksimum yang diizinkan.

Penyelidikan geoteknik merupakan pekerjaan yang menghasilkan data - data penunjang dalam pekerjaan perencanaan suatu bangunan. Didalam kegiatan perencanaan, penyelidikan geoteknik harus dilakukan secara baik sehingga dihasilkan gambaran yang jelas mengenai index properties dan engineering properties dari tanah. Analisis geoteknik dilakukan untuk dapat mengetahui stabilitas dan daya dukung tanah dalam menerima beban struktur diatasnya. Untuk mengetahui struktur tanah dan daya dukung tanah di lokasi perencanaan proyek pembangunan Instalasi Ibu Kota Kecamatan (IKK) Pelaihari Perusahaan Daerah Air Minum Kabupaten Tanah Laut maka dilakukan analisis perhitungan daya dukung tanah menggunakan data sondir dari dua titik sondir dengan menggunakan tiga metode yaitu metode Van Der Ween, metode Philipponant, dan metode Mayerhoff. Berdasarkan hasil perhitungan nilai daya dukung pondasi bore pile dengan menggunakan tiga metode dihasilkan nilai daya dukung yang berbeda – beda. Untuk perhitungan menggunakan metode Van Der Ween hasil nilai daya dukung ultimit (Qult) 213.20 ton dengan daya dukung izin (Qizin) 71.06 ton untuk titik sondir S.02 dan 193.52 ton dengan daya dukung izin (Qizin) 64,50 ton untuk titik sondir S.03. Perhitungan menggunakan metode Philipponant   hasil nilai daya dukung ultimit (Qult) 136.51 ton dengan daya dukung izin (Qizin) 45,50 ton untuk titik sondir S.02 dan 135, 06 ton dengan daya dukung izin (Qizin) 45,02  ton untuk titik sondir S.03. Dan untuk perhitungan metode Mayerhoff hasil nilai daya dukung ultimit (Qult) 654.37 ton dengan daya dukung izin (Qizin) 218,12 ton untuk titik sondir S.02 dan 702.73 ton dengan daya dukung izin (Qizin) 234,24 ton untuk titik sondir S.03. Kata Kunci: sondir, daya dukung, Van Der Ween, Philipponant, Mayerhoff

Small- and medium-sized enterprises (SMEs) are part of the building construction industry. Although many effect analyses of applying building information modeling (BIM) to projects have been conducted, analyses from the perspective of SMEs are lacking. We propose a BIM-based construction of prefabricated steel framework from the perspective of SMEs. We derive the essential functions of the system from the viewpoint of SMEs and verify the qualitative effect through a case analysis of prefabricated steel frame construction that is based on BIM. The following system functions and qualitative effects are analyzed according to project stages that are based on interviews of working groups participating in system development and case projects. (1) Preconstruction stage: extraction of fabrication drawing and review of shop drawing, (2) fabrication stage: prefabrication review, steel member removal, and field loading review, and (3) construction phase: integrated management of cost and schedule and quality management. The expected effects of applying the system are qualitatively and quantitatively analyzed through expert group interviews and surveys. For the quantitative analysis, an evaluation index is used for the end-user computing satisfaction survey. Further analysis of the finishing and installation work is required. Future research should also analyze the effect of system application on human resource management.

Construction project activities have various risks during their implementation. Every work item on the project has different levels of risk and can affect the project so that it will have an impact on increasing cost and time of project completion. PT. Adhi Karya Tbk is carrying out the project of Andalas University Hospital, where in its implementation there will be many possibilities of risks that will occur. Therefore, it is necessary to identify and analyze the variables of risks that may occur as well as proposing appropriate risk mitigation measures for minimize the potential risks. Risk identification and risk analysis were done using Risk Breakdown Structure (RBS) and Analytic Hierarchy Process (AHP) method respectively. Based on data compilation, variables of risk are grouped in 4 types, namely risk of engineering consist of 8 variables, risk of production consist of 5 variables, risk of construction consist of 9 variables and risk of financial consist of 2 variable, with total of risk are 24 variables. Risk analysis with AHP method is obtained 5 (five) risk priority based on the highest value on each risk type. The five priority risks were a risks of increasing of material prices (extreme), a risk of increasing of procurement costs (high), workplace accidents risk in the project area (medium), mistaken translating the DED to shop drawing (medium) and a quality of goods and services produced by vendors not meet the specifications in contract (medium). To reduce the possibility and impact the risks posed mitigation measures for the risk priority highest were proposed.

Reinforcement Bar

Structural building information modeling (S-BIM) for reinforced concrete walls based on parametric technique has studied. There are structural analysis and design packages for reinforced concrete structures. 3D BIM platforms which are recently developed and widely adopted in the construction industry are mostly experiencing a difficulty in interoperability with structural analysis and design packages. The modeling of reinforcement placement in the reinforced concrete structures can not be performed using current BIM platforms based on the result of structural analysis and design. This study develops the algorithm and implementation of integrated reinforcement bar placement system by creating a database that stores the results of structural analysis and design so that overall reinforced concrete model including re-bar can be built. Utilization of S-BIM can reduce the time of engineering, the production of working drawing and shop drawing.
