Prediction and Optimization of Sulphur Trioxide Yield from Calcination of Aluminium Sulfate Using Central Composite Design

Summary/Abstract: Knowledge generated during construction projects is wasted as a result of a lack of awareness of the benefits of sharing knowledge. Moreover, knowledge is scattered in the construction firms through various documents and individual brains without a platform to retrieving it for sharing among the employees. Therefore, this paper aims to assess knowledge sharing practices in Nigerian construction firms. A detailed review of relevant literature was conducted with the view of collecting relevant data necessary for this paper. A total of 150 numbers of questionnaires was distributed to Engineers, Quantity surveyors, Builders and Architects in construction firms that are based in Abuja. The descriptive method of analysis was used to analyze the data obtained from the survey. The result shows the followings as methods of knowledge sharing practices in Nigerian construction firms: (1) face to face interaction, (2) site & Departmental meetings, (3) mentoring and tutoring, (4) project briefing and interviewing session, and (5) internal training courses. In addition, the followings were established as construction activities that are commonly used for knowledge-sharing practices: (1) site visitation, (2) estimation & price forecasting, (3) evaluation of BOQ, (4) preparation of scheduling for site activities, (5) development of tender programme, (6) taking off and (7) understanding of construction technologies and methods. Therefore, the paper recommended that the top management should encourage knowledge-sharing practices in the construction firms through face to face interaction, seminars/workshops, and post-project review.
