Building Information Models

BIM can be used to illustrate the entire building lifecycle, from cradle to inception, design and demolition and materials reuse; quantities and properties of materials, which can be easily extracted from the model; and the scope of works, including management of project targets and facilities management throughout the building’s life. The implementation of BIM in projects or organization is in phases and building information models can be developed as 2D, 3D, 4D, 5D and 6D BIM depending on the stage of BIM implementation and level of details required. This study examined the levels of details of building information models being generated by two hundred and eighty two construction professionals in Lagos State, Nigeria using respondents driven sampling technique. Frequency distribution and percentage, clustered bar chart, mean ranking, Kruskal Wallis test and Fisher exact test were used to analyse the data obtained from the respondents. The study found that the implementation of BIM in the study area is for visualization purpose. The findings also revealed that the levels of generating 2D and 3D BIM were very high in the study area; and that 3D architectural model, 3D architectural and structural model, and 3D architectural and building services model were the most developed variants of 3D BIM. It was concluded that that the status of BIM adoption in construction industry in Lagos State, Nigeria is at the visualization phase.Keywords: BIM details, BIM, BIM development, 4D BIM, federated BIM.

Abstract: Staphylococcus is a cause of infection. Infection can be transmitted from a source by an indirect through fomite. Paper money can act as transmission of infectious agents, money acts as a fomite. Smaller denominations of value have higher contamination. This study aims to analyze differences in contamination bacterial Staphylococcus sp on denomination of paper money Rp.2.000, 5.000, Rp.10,000 and Rp.20.000 that currently shop on Adi Sucipto street town Pontianak. The research method used in this research is in the form of difference and the sample in this research is denomination of paper money curently with sampling technique using cluster sampling. Checkup of Staphylococcus spon denomination of paper money using rinse method. On these result of study, denomination of paper money Rp.2.000 that is contaminated staphylococcus sp is 80%, denomination of paper money Rp.5.000 that is contaminated staphylococcus sp is 70%, denomination of paper money Rp.10.000 and Rp.20.000 that is contaminated staphylococcus sp is 80%. The data from result of study has been obtained were analyzed statistically by using fisher exact test, the result of p (0,477) >α (0,05) which mean as H1 is rejected. So it can be concluded there is no difference of contamination bacteria staphylococcus sp on denominations of paper money rupiah.Abstrak: Staphylococcus merupakan penyebab terjadinya infeksi. Infeksi dapat ditularkan dari suatu sumber dengan mekanisme tidak langsung melalui fomite. Uang kertas dapat bertindak sebagai transmisi agens infeksius ,uang berperan sebagai fomite. Pecahan uang yang lebih kecil nilainya memiliki kontaminasi yang lebih tinggi. Penelitian ini bertujuan untuk menganalisis perbedaan cemaran bakteri Staphylococcus sp pada pecahan uang kertas Rp.2.000, 5.000, Rp.10.000 dan Rp.20.000 yang beredar di warung jalan Adi Sucipto kota Pontianak. Metode penelitian yang digunakan dalam penelitian berbentuk komperatif dan sampel pada penelitian ini adalah pecahan uang kertas rupiah dengan.teknik pengambilan sampel menggunakan purposive sampling. Pemeriksaan Staphylococcus sp pada pecahan uang kertas rupiah menggunakan metode rinse. Pada hasil penelitian pecahan uang kertas Rp.2.000 yang tercemar staphylococcus sp adalah 80%, pecahan uang kertas Rp.5.000 yang tercemar staphylococcus spadalah 70%, pecahan uang kertas Rp.10.000 dan Rp.20.000 yang tercemar staphylococcus spadalah 50%. Berdasarkan data dari hasil penelitian yang telah didapat dianalisis menggunakan uji statistik fisher exact, didapatkan hasil p (0,477) >α (0,05) yang diartikan sebagai H1 ditolak. Sehingga dapat disimpulkan tidak ada perbedaan cemaran bakteri staphylococcus sp pada pecahan uang kertas rupiah.
