  • Comparison of HadCM3, CSIRO Mk3 and GFDL CM2.1 in Prediction the Climate
           Change in Taleghan River Basin

    • Authors: Arash YoosefDoost; Icen YoosefDoost, Hossein Asghari, Mohammad Sadegh Sadeghian
      Pages: 93 - 100
      Abstract: Climate change is a complex and long-term global atmospheric-oceanic phenomenon which can be influenced by natural factors such as volcanoes, solar, oceans and atmosphere activities which they have interactions between or may be as a result of human activities. Atmospheric general circulation models are developed for simulation of current climate of the earth and are able to predict the earth's future climate change. In this paper, the performance of GFDL CM2.1, CSIRO Mk3 and HadCM3 AOGCMs were assessed and evaluated in the study of the climate change effects on temperature and precipitation in Taleghan basin. The results show that HadCM3 model in comparison with CSIRO Mk3 and GFDL CM2.1 models has indicated the better performance in this region.

  • Architectural Documentation and Virtual Reconstruction of Samtenchoeling
           Monastery Ruins at Chumme, Bumthang Bhutan

    • Authors: Dhrubaraj Sharma
      Pages: 101 - 104
      Abstract: Monasteries have played significant role in the birth and spread of Buddhism in Bhutan since ancient times. Bumthang district in central Bhutan has some of the ancient monasteries in the country and many of them are in need of restoration and conservation however due to lack of proper documentation the government and the scholars are not aware of them. The ruin of Samtencholing Monastery at Gaytsa Village under Chumme Gewog is one of the important Buddhist sites in the cultural landscape of the country. This study documents the existing ruins and traces the original form of the monastery and connects it to Kunkhen Longchen Rabjampa the founder of the Nyingthing (heart essence) tradition in Bhutan, one of the greatest of all Nyingma masters of Mahayana Buddhism. The paper attempts to reconstruct the monastery’s ruin to its original form through drawings and three dimensional views. The research recommends the need to restore the monastery to enrich community vitality and boost pilgrimage tourism in the locality.

  • Variation Mitigation Model to Enhance Construction Performance of Public
           Building Projects in Tanzania

    • Authors: Yusuph B. Mhando; Ramadhan S. Mlinga, Henry M. Alinaitwe
      Pages: 105 - 118
      Abstract: Detrimental variations are variations which negatively impact the project performance resulting into scenarios such as cost overruns, time overruns, project abandonment, rework, disruption and conflicts. These scenarios have led to non-fulfillment of project objectives. The objective of the study was to develop a mitigation model that helps to mitigate detrimental variations in public building projects in Tanzania. Specifically, the research question was how can detrimental variations be minimised in building projects' Literature review was carried out. Data were collected using questionnaire survey, group discussion and case studies. In total, 143 professionals (architects, engineers, quantity surveyors and procurement officers) participated in the survey. Statistical analyses such as Analysis of Variance (ANOVA), T-test analysis, Spearman’s rho correlation analysis and Principal Component Analysis (PCA) were used to analyse data and obtain relationships of variables. The analysis generated significant independent and dependent variables that formed the basis for the developed detrimental variation mitigation model. The model was validated through focus group discussion to test the model’s usefulness, clarity and applicability. Findings from case studies suggest that building projects suffered detrimental variations. The developed model when used significantly contributes to reduction of detrimental variations. Project parties should use the developed best practice model to enhance performance of construction projects.

  • Potassium Nitrate as an Accelerator in Plain Concrete

    • Authors: Amaziah Walter Otunyo; Ekiti Godknows
      Pages: 119 - 122
      Abstract: The effect of potassium nitrate as an accelerator in plain concrete was investigated. Fifteen concrete cubes were cast with 0, 5, 10, 15 and 20 % by weight of potassium nitrate. The compressive strength was measured after 7, 14 and 28 curing days Other parameters including the workability, initial and final setting times were tested. Compressive strength of the plain concrete decreased as the content of the potassium nitrate increased. The workability and setting times decreased as the content of the potassium nitrate increased.

  • Risk Factors in Cost Estimation: Building Contractors’ Experience

    • Authors: Harriet Eliufoo
      Pages: 123 - 128
      Abstract: The study has examined risk factors in cost estimation of building construction projects. An investigation was made of risk emanating from risk factors as perceived by building contractors. Data was collected by use of questionnaires were a total of 61 questionnaires were administered to building contractors. The analysis considered four categories of risk factors: construction, physical, financial and estimator’s risk factors. The results show estimator’s risk factors as perceived to have the highest risk on cost estimates. Overall respondents view indicate all four categories of risk factors have an influence to project performance at a range of moderate to high. The study has also established potential risks that originate from risk factors. Such risks are noted to work against the achievement of project goals and include amongst others, project delays, cost overrun and performance failures. It is hence recommended by the study for not only contractors to be vigilant in mitigation of risk factors, but clients as well should also take this initiative as they are bound to suffer when inaccurate cost estimates are committed to a project.

  • Effect of Crushed Waste Ceramic Tiles (CWCT) as Partial Replacement for
           Fine Aggregate in Concrete

    • Authors: Amaziah Walter Otunyo; Uwakwe Paul Arinze
      Pages: 129 - 132
      Abstract: The reuse of crushed waste ceramic tiles as a substitute for fine aggregate in concrete has been investigated in this study. Waste ceramic tiles obtained from building demolition sites and left-overs from new building sites were used. The crushed waste ceramic tiles were substituted in place of fine aggregates in the following percentages (0%, 20%, 25%, 30% 35% and 40%) in the concrete mix. The water /cement ratio used was 0.6. The compressive strength of the concrete cast with the above partial replacement of fine aggregate were determined after, 7 and 28 days age of curing. The flexural strength was determined after 28 days. The results indicate that the maximum compressive and flexural strength is obtained at 40% replacement level of fine aggregate with crushed was ceramic tiles.
