Abstract: This research aimed at investigating the causes and effects of abandoned building construction project in Abuja Municipal Area Councils (AMAC) of FCT, Nigeria so as to proffer solution to the problem(s). This research uses a qualitative method of research in which a structured close ended questionnaire was prepared to capture information on the causes and effects of abandoned building construction projects in AMAC. It was on this basis that a structured questionnaire with Likert Scale design method was adopted. One hundred and ten (110) consultants obtained from professional bodies like Council for Regulation of Engineering (COREN), Council of Registered Builders of Nigeria (CORBON), Architect Registration Council of Nigeria (ARCON), Quantity Surveyors Registration Board of Nigeria (QSRBN) and Procurement Consultants were contacted to get their views on abandonment of building construction project. Eighty-Eight (88) responses were obtained to give a return rate of 80%. All information found were analysed using the Relative Importance Index (R.I.I) formula. The higher the Relative Importance Index value, the more significant is the cause or effect of abandoning building project. Sixteen (16) important causes of abandoning building construction project and nine (9) main effect of abandoning building construction project were identified. This research therefore concluded that if the causes and effects of abandoning building construction projects are corrected through the application of numerous recommendations made on this research, building construction project abandonment will be history in the research area and indeed the country at large.Abstract: This research aimed at investigating the causes and effects of abandoned building construction project in Abuja Municipal Area Councils (AMAC) of FCT, Nigeria so as to proffer solution to the problem(s).

Abstract: Now adays, due to architectural and structural requirements, complicated tall and slender buildings with various corner configurations and cross-sectional shapes are emerged, which are difficult to design using the existing wind load standards as well as using available software packages. For such conditions, an experimental study is the best solution to develop new standards and solve such design limitations. In this study a total of five rigid plywood models of equal height are prepared at a scale of 1:100, the principal model is a rectangular building with the geometry of B*D*H, 200mm*300mm*500mm and other models are vertically chamfered edges as B/8, B/4, 3B/8, and B/2. In properly designed open rectangular boundary layer wind tunnel with 2m*2m*15m simulation section at IIT Roorkee, India. The model is placed on the top floor and the mean wind velocity profile of approaching flow 9.61m/sec corresponding to terrain Category-II is allowed to pass through the circuit and various digital signal readings are taken at various wind incidences then converted to forces, moment, coefficients and results are compared with existing codes. As vertical chamfering size increases, twisting and torsional moment increases, drag force coefficient and lift-force coefficient increase due to the slenderness of the chamfered building compared with the principal building.Abstract: Now adays, due to architectural and structural requirements, complicated tall and slender buildings with various corner configurations and cross-sectional shapes are emerged, which are difficult to design using the existing wind load standards as well as using available software packages.
