The permeability of concrete to water is an important factor that have an effect to durability of concrete structures having direct contact with water, such as port structures, bridges, and basements. In order to identify the permeability nature of concrete, permeability testing is needed. This paper presents a concrete permeability test equipment that was designed and built by the authors. The equipment can be used to conduct permeability tests by flow test as well as by penetration test method. The trial tests of the equipment by flow test method were conducted to 12 concrete speciments with water-cement ratio 0.4 and 0.5 and with wet and dry curing method. The averages of coefficients of permeability obtained differ in the range of 5%-26% from that obtained by using permeability test equipment made by Marui. In addition, the trial tests by penetration method were also conducted to six dry-cured concrete speciments with water-cement ratio 0.4 and 0.5. The averages of coefficients of permeability obtained from the penetration test differs from the flow test 23% and 90% for concrete of water –cement ratio 0.4 and 0.5, respectively. Abstract in Bahasa Indonesia : Permeabilitas beton terhadap air merupakan faktor penting yang mempengaruhi durabilitas struktur beton yang berhubungan langsung dengan air, seperti pelabuhan, jembatan, dan basement. Untuk mengetahui karakteristik permeabilitas beton diperlukan uji permeabilitas. Makalah ini menyajikan suatu alat uji permeabilitas beton terhadap air yang dirancang dan dibuat oleh penulis. Dengan alat ini uji permeabilitas beton dapat dilakukan baik dengan cara aliran maupun cara penetrasi. Ujicoba penggunaan alat ini dilakukan dengan cara uji aliran terhadap 12 sampel beton dengan variasi faktor air semen 0.4 dan 0.5 serta variasi curing kering dan basah.

The essence of building design process and management for building sustainability in the creation and maintenance of a qualitative architectural product is investigated in this paper. The design process, concept of building sustainability and particularly the quality of the built environment are discussed. Akure, a state capital in Nigeria was used as a case study. The principles and indicators for sustainability of buildings and its implications on the quality of the environment are examined in details. Survey findings include the views of the professionals on the clients, perception on the design process as well as management of projects, and the implications on the quality of the ensuring products and the cityâs environment. The data were factor analyzed using varimax rotation criterion (with Kaiser Normalization). The results revealed that five factors were effective, with one of them exhibiting the greatest variability and individual differences. The variables that loaded on this factor were really the aspects of the process and management relating to the clients. The findings also revealed the professionalsâ wrong attitude towards design process as shown with a very high degree of variability in the study. The paper concludes by recommending the enactment and enforcement of relevant policies with adequate education of the people and the involvement of all the stakeholders in the management of building projects and environmental programmes for the realization of a qualitative architectural product.

The construction industry has been consistently criticized for poor performance in attaining clients’ requirements. The study, thus, assessed the factors predisposing building elements to variation with a view to providing cost-design information that enhance construction project delivery, that is, on-time completion of project within budget. The building elements considered in this study include substructure, frame, upper floors, and roof. Data were collected using well-structured questionnaires administered on professionals in consulting firms, contracting firms, and client organizations in Lagos metropolis. Data analysis was done using descriptive and inferential statistics. The results of the analysis revealed nine factors through factor analysis that predispose substructure to variation, seven factors predispose frame, six factors predispose upper floors, and seven factors predispose roofs to variation during construction process in Nigeria.

Knowledge of the market is a requirement for a successful provision of public transportation. This study aims to explore public perception of paratransit service, as represented by the user and non-user of paratransit. The analysis has been conducted based on the publicâs response, by creating several binomial logistic regression models using the public perception of the quality of service, quality of car, quality of driver, and fare. These models illustrate the characteristics and important variables to establish whether the public will use more paratransit in the future once improvements will have been made. Moreover, several models are developed to explore public perception in order to find out whether they agree to the replacement of paratransit with other types of transportation modes. All models are well fitting. These models are able to explain the respondentsâ characteristics and to reveal their actual perception of the operation of paratransit. This study provides a useful tool to know the market in greater depth.

Many changes in building construction cost evoked by inflation recently, make an analysis of the relation between building construction cost and inflation is needed. In this analysis linear regression method is used to obtain the influence of inflation to building construction cost and the relationship between this two parameter. Element with the highest influence of inflation to precentage cost and per square meter cost for industrial building, housing and office building is structure. Element which precentage cost has the closest relationship with inflation is sitework for industrial building, structure for housing, thermal and moisture protection for office building. Element which per square meter cost has the closest relationship with inflation for industrial building is doors and windows, structure for housing, thermal and moisture protection for office building Abstract in Bahasa Indonesia : Banyaknya perubahan dalam biaya konstruksi bangunan akibat laju inflasi yang terjadi beberapa tahun terakhir ini, mendorong diperlukannya analisa hubungan antara biaya konstruksi bangunan dengan inflasi.

Efforts to reduce construction accidents can be initiated by building good safety culture. Researches concerning safety culture, however, are still limited. This research aims to empirically gauge workerâs perception toward safety culture in construction projects. Data were obtained through questionnaire survey to three large construction projects in Surabaya. Two hundreds and seven sets of questionnaires were gathered and used for subsequent analyses. Results show that in general workersâ perception toward safety culture are quite good. Further analysis indicates that workers in the three projects have different safety culture perceptions, especially on factors of top management commitment, safety rules and procedures, communication, and workerâs competency.

Seismic Progressive Collapse: Qualitative Point of View H. Wibowo; D. T. Lau
Civil Engineering Dimension Vol. 11 No. 1 (2009): MARCH 2009
Publisher : Institute of Research and Community Outreach - Petra Christian University

Progressive collapse is a catastrophic structural phenomenon that can occur because of human-made and natural hazards. In progressive collapse mechanism, a single local failure may cause a significant deformation which then may lead to collapse of a structure. The current practices in progressive collapse analysis and design method generally focus on preventing progressive collapse due to abnormal gravity and blast loads. Progressive collapse behaviour of structures due to earthquake loads has not received as much attention. This paper presents a brief overview of the current state-of-knowledge, insights, and issues related to progressive collapse behaviour of structures caused by earthquake loading.

Civil Engineering Dimension Vol. 17 No. 3 (2015): SPECIAL EDITION
Publisher : Institute of Research and Community Outreach - Petra Christian University

Systems thinking is a widely recognized and subscribed-to concept. Many benefits are ascribed to systems thinking and its result - the holistic solution. Yet, there is a wide range of opinion as to what systems thinking really is, and how its benefits can be realized in engineering practice. In fact, the concept of what constitutes a ‘system’ is wide and variable. The purpose of the paper is to draw together diverse perspectives of systems thinking useful in engineering, and to present a set of core concepts that are useful in the successful design and operation of engineered systems. These concepts will be illustrated with examples drawn from the author’s experience in teaching and research on engineered systems.

Publisher : Institute of Research and Community Outreach - Petra Christian University

Improvement of tensile strength in fiber reinforced soil is an important research topic. A study has been undertaken to investigate the strength of stabilized clay-soil reinforced with randomly distributed discrete plastic waste fibers by carrying out split tensile strength test. In this study, the clay soil was stabilized with lime and rice husk ash mixtures. The main purpose of this research is to investigate the effect of specimen size to the tensile strength behavior. Testing procedure was formulated using extended ASTM C496 standard. The laboratory investigation results showed that split-tensile strength of reinforced specimens increased with increase in size. The limitations of the dataset indicate that specimen size of 70 mm in diameter is the threshold to produce reasonable representative strengths.
