Abstract: Building Information Modeling (BIM) is an intelligent 3D model-based process that gives architectural, engineering, and construction (AEC) professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructures. The introduction and implementation of BIM has brought changes in the construction’s traditional procurement system and this has made its adoption a bit slow and difficult to take off swiftly and more officially. Previous researches have identified gaps in contractual relationships, roles and the resulting risks in BIM implementation. This paper focuses on the adoption of BIM in the Ghanaian Construction Industry thereby highlighting the concept of BIM in enhancing productivity and also determines the level of knowledge and awareness of BIM by industry players and stakeholders as well as establishing the extent of usage of BIM in the Ghanaian construction industry. A descriptive survey research was conducted with both structured and unstructured questionnaire and administered both via e-mail and by sending questionnaire link onto a WhatsApp platform groups of the respondents and out of the 263 respondents that took part in the survey, 78 respondents feedback were incomplete so 185 member respondents results were analyzed in the form of bar charts, column chart and pie chart representing 70.3% response rate. The research survey respondents comprised of Civil Engineers, Construction Project Managers, Architects, Electrical Engineers, Quantity Surveyors, Mechanical Engineers, Contractors and Facility Managers. The survey results revealed that there is a low level of knowledge of Building Information Modeling (BIM) and its concept in the Ghanaian Construction Industry which is also associated with the low level of awareness, utilization and adoption among stakeholders. BIM therefore represents a new paradigm within AEC that encourages integration of the roles of all stakeholders on the effective execution of projects and therefore edge the participation of relevant professional bodies to facilitate its implementation in order to ensure adequate knowledge of BIM towards improving productivity and efficiency in the Construction Industry.

Abstract: Procurement as one of the core functions of public sector agencies in Uganda has become a big matter of concern as expenditure on its processes have continued to be alarmingly high in government departments including local governments. This study assessed the effects of procurement processes on performance of construction contracts in Local Governments in Uganda. The study adopted a descriptive research design and used purposive sampling to sample 81 respondents. Data were collected using questionnaire and analyzed using SPSS software. The study revealed that poor procurement planning led to big budget deficits with a mean of 1.86 thus affecting performance of construction contracts to a very large extent. The study further revealed that funds for the construction contracts are not always released in time and this has a big effect on performance of construction contracts. The study concluded that procurement planning and contract monitoring and administration have a significant effect on the performance of construction contracts in District Local Governments in Uganda. The study recommended that Local Governments should adopt the developed model to control the procurement process and other anomalies in the award and management of construction contracts.

Abstract: The aims of the research report are (1) low-income communities knowledge, attitudes, motivation, and behavior on the making of safe and environmentally friendly latrines and (2) to find the effect of experiments on increasing knowledge, attitudes, motivation, and behavior of low economic communities in the coastal areas of South Sulawesi during Covid-19 Pandemic. The sample of the experimental group are 30 heads of family area was Kanaungan Village, and the control group is 30 heads of family were selected by purposive sampling method area was Ma'rang Village in Pangkep Regency South Sulawesi, one of the Indonesian provinces. The research variables: (1) knowledge, attitude, motivation, and behavior, and (2) the effect of experiments on increasing knowledge, attitudes, motivation, and behavior. The experimental design used was a pretest-posttest control group design. The analysis used is descriptive statistical analysis and inferential statistical analysis. The inferential model is the independent t-test. The results of the research have shown that (1) knowledge, attitudes, motivation, and behavior to use safe and environmentally friendly latrines has increased after the experiments, and (2) there is a significant impact of the experiment in nurturing knowledge, attitudes, motivation, and behavior of the low economic communities in the coastal areas of South Sulawesi.

Abstract: The construction industry plays a significant role in integrating the economy of any developing country. It is also noted that the increasing rate of building construction projects has led to the increasing demand of competent first line managers in the building construction industry, who possess the right skills to effectively manage and supervise construction projects. First line managers’ incompetence leads to cost and time overruns as well as poor quality work thus affecting labour productivity. This study investigated the impact of management skills on the productivity in the building construction industry in Uganda. Both quantitative and qualitative research approaches were used to collect data from 155 respondents who were purposively selected. Management skills were categorized under three groups: conceptual, interpersonal and technical skills. Their impacts were assessed using Relative Importance Index (RII) as a basis for analysis. Regression analysis in R-Studio software was employed to develop a model, to be used in prediction and to forecast the impact of construction management skills on labour productivity during building construction stages. Findings revealed technical skills as the most significant management skills, followed by interpersonal skills and lastly conceptual skills. Model results showed existence of a fairly strong correlation between construction management skills and productivity. Based on the model results, the study concluded that there is significant impact of construction management skills on labour productivity in the building construction industry. It is recommended that adequate attention should be paid to training, retraining and continuous professional development of people charged with supervisory roles on construction sites so as to achieve higher construction workers productivity.

Abstract: The artisan clay bricks in Uganda are characterised with low strength, erosion, tiny cracks, lime pop out, warping, efflorescence occurrence and high-water absorption. The raw clay and artisan burnt clay brick samples were collected from artisan brick making places (sites) from Eastern, Central and Northern Uganda. The sampling was done using IS-5454 procedures. Testing was carried out for; water absorption, mineral percentage investigation in natural and purified clay in terms of SiO2, Al2O3, Fe2O3 & CaO, compressive strength of the artisan clay unit, improved chemical composition artisan clay units from purified clay and improved molded bricks from raw clay. Results indicated mineral requirements for manufacturing bricks was not satisfactory, for artisan bricks, they had very low characteristic strengths of 0.63N/mm2 for Lira and 0.38N/mm2 for Mukono. Refining and change on molding process was done and the raw clay structure shifted to the positive side of the required mineralogy. Fired bricks on testing gave higher characteristic strengths of 2.2 (improved chemical composition bricks) and 3.3 (improved molded bricks) for Lira, 5.12 (improved chemical composition bricks) and 2.62N/mm2 (improved molded bricks) for Mukono, slight efflorescence and low water absorption. Studies therefore recommend that the artisan do include both refining processing and constant force kneaded clay pressing in the manufacturing process.
