    Cost estimation is the art of estimating the amount of cost required for an activity based on available information. The conceptual cost estimate is an early stage in planning a construction project. This estimate provides the cost that must be budgeted for a construction project. Cost conceptual estimates have low accuracy because the time of calculation and available information is limited. This study aims to obtain a conceptual model of the conceptual cost of short-spaced bridges. The method used is the cost index. The cost index is a figure indicating the cost per m2 of bridges at a given time. The required data are contract documents and drawings design that are built in 2012 - 2015 in Banyumas residency area. Span of bridge 4 - 38.8 meters and width of bridge 2 - 7 meters with caisson  foundation. The data were obtained from Dinas Bina Marga and Public Works Agency. The results showed that the conceptual cost model of reinforced concrete bridge with caisson foundation was BJiL = (100.540.56t2-404.528.636,58t + 406.914.286.088,58) x P x W, with t = year, P = span bridge, and W = bridge width. The error value of validation of this model is 2.31%

    The growth of high-rise buildings is triggered by expensive land prices and the need for construction for hotels, offices, and colleges. Besides the great benefits, high-rise building also has a consequence of fire risks. This indicates that its extinction is challenging with the occurrence of fire outbreaks, due to the flammable furniture and characteristics of high-rise buildings. To anticipate this condition, fire safety protection in high-rise buildings should be reliable. Furthermore, the Indonesian government has reportedly issued regulations and technical guidelines regarding the reliability of fire safety, although fires still occur and cause loss of life and property. Science and engineering also provide a performance-based alternative approach. Therefore, this study aims to analyze the reliability of the fire safety model produced from the integration of FSM (Fire Safety Management) variables, namely flame prevention, people safety, monitoring, audit, review and reactive assessment. In a high-rise building, the initial model was validated by experts within the fire safety field. At the initial stage, the identification of FSM implementation was carried out for building functions in Jakarta, where construction surveys were conducted using a questionnaire and checklist for the completeness of the protection system. Using a spreadsheet and the Smart PLS application, the data were also processed to produce the implementation of FSM and test the effect of independent variables on the dependent factors, respectively. Subsequently, the sub-variables with low FSM implementation were used to improve the fire safety conditions in buildings. By implementing all FSM variables, reliability was then achieved, as improvement efforts were prioritized on the sub-variables with low implementation and priority on fire prevention and monitoring, audit, and review. The integration of the FSM variables' implementation also consistently produced fire safety reliability, as well as guaranteed life and property protection

    ABSTRAKPelat lantai merupakan bagian yang banyak dilalui berbagai alat berat dan kendaraan pada bangunan industri, gedung parkir, dan pergudangan. Oleh karena itu, dibutuhkan beton yang berkualitas baik untuk menghasilkan struktur bangunan kuat dan tahan lama. Proses pengecoran pelat lantai biasanya banyak terjadi penurunan agregat kasar sehingga permukaan pelat hanya tersisa agregat halus. Hal ini menyebabkan daya tahan aus dan kuat tekan beton menjadi rendah. Pengikisan terus menerus permukaan lantai pelat beton mengakibatkan penurunan dari mutu beton itu sendiri. Floor hardener merupakan bahan tambah yang bisa digunakan untuk meningkatkan ketahanan aus permukaan beton. Penelitian ini bertujuan untuk mengetahui pengaruh floor hardener terhadap ketahanan aus dan kuat tekan beton. Pengaruh penggunaan floor hardener juga akan meningkatkan biaya satuan untuk pekerjaan pelat beton tersebut sehingga faktor biaya juga ditinjau dalam penelitian ini. Dosis floor hardener yang digunakan pada beton yaitu  0, 3, 5, dan 7 kg/m2. Hasil pengujian menunjukkan bahwa kuat tekan mengalami peningkatan sebesar 3.18%, nilai abrasi beton turun 24.34%, dan semakin tinggi dosis floor hardener yang digunakan, semakin mahal pula biaya satuan pekerjaan pelat beton.Kata Kunci: Floor hardener, Kuat Tekan, Ketahanan Aus, BiayaABSTRACTThe floor plate is the part that is often passed by various heavy equipment and vehicles in industrial buildings, parking buildings, and warehousing. Therefore, good quality concrete is needed to produce a strong and durable building structure. The process of casting floor slabs usually occurs a lot of decrease in coarse aggregate so that the surface of the slab is left with only fine aggregate. This causes the wear resistance and compressive strength of concrete to be low. Continuous abrasion of the concrete slab floor surface results in a decrease in the quality of the concrete itself. Floor hardener is an additive that can be used to increase the wear resistance of concrete surfaces. This study aims to determine the effect of floor hardener on the wear resistance and compressive strength of concrete. The effect of using floor hardener will also increase the unit cost for the concrete slab work so that the cost factor is also reviewed in this study. The floor hardener doses used in concrete are 0, 3, 5, and 7 kg/m2. The test results show that the compressive strength increased by 3.18%, the concrete abrasion value decreased by 24.34%, and the higher the dose of floor hardener used, the more expensive the unit cost of the concrete slab work.Key words: Floor hardener, Compressive Strength, Wear Resistance, Unit Cos

While high rise building provides great benefits, it also has negative consequence with regard to increasing risks of fire in building. High rise building fire could cause fatalities and losses. To overcome it, an integrated and efficient fire safety strategy is required. To date, the approaches for safety are design, implementation and maintenance of fire protection system from the stage of pre-construction, construction and post-construction using traditional methods. Building Information Modelling (BIM) is a process of modelling a building that initially is based on 3D and it has been enhanced to 7D that provides information and tools to help planning and designing in construction process to be more efficient and effective.  At its initial emerge, BIM were used to help planning, construction and operational of buildings. Recently, BIM has also been employed to improve fire safety. This study aims to extend the application of BIM on fire safety in high rise building using the approach of utilizing its potency from the pre-construction, construction and post-construction stage, as well as identifying equipment’s and works related to fire safety that support fire safety enhancement on high rise buildings. The method implemented was qualitative descriptive that performed using literature review and expert validation through in-depth interview. The result is an ideal projection of BIM implementation to heighten fire safety on high rise buildings. The projection was validated using BIM and fire safety experts.Key words: building information modelling (BIM), fire safety, high-rise buildin
