Architectural design firms deploy design technologies for design, modelling and other services. Autodesk AutoCAD is deployed by 90% of these firms in Nigeria. The paper utilized integrated Task-Technology Fit (TTF) model to measure deployment. Multiple regression analysis of the survey reveals ease-of-locating data as highest predictor of the fit model.

Vertical circulation is a key factor in optimizing the design of any multi story building and the key to a successful functioning of the building design. For a multistory building, the placement of the stairs, escalators, and elevators frequently determines the floor design, further aiding in the building's optimization. The methodology for this research is the qualitative one using the observation and site survey of the selected buildings in the school. In order to accommodate the expanding student population and ensure that students with special needs may participate in the educational system, school designs must be developed from outward horizontal layouts to upward vertical structures. As a result, this study looked at the efficiency of vertical accessibility components in multi-story buildings at Caleb University, Imota Lagos, Nigeria in order to identify areas for improvement and contribute to ways of promoting social inclusion in educational settings. A digital camera and a study-developed observation guide were used. It is recommended that the management of Caleb University will respond positively by creating a more conducive vertical movements and ramps where necessary as pointed out by this research. Researchers, students, educators, policymakers, and building design professionals will find this study beneficial in resolving concerns related to universal design of the academic built environment, particularly in terms of ensuring adequate vertical movement elements in high-rise public buildings.

Cracks in concrete have many causes. They may affect appearance only, or may indicate significant structural distress or a lack of durability. Cracks may represent the total extent of the damage, or may point to problems of greater magnitude. Their significance depends on the type of structure and nature of the cracking. This is a review paper that proposes guidelines for crack evaluation and repair of concrete structures. The causes of cracks in concrete are examined along with the principal procedures used for crack control considering both plastic and hardened concrete. The paper presents the importance of design, detailing, construction procedures, concrete proportioning, and material properties. Relevant techniques and methodology for crack evaluation were identified and the need to determine the causes of cracks as a necessary prerequisite to repair is emphasized. The selection of successful repair techniques should consider the causes of cracking, while identifying active or dormant status, and the need for repair. Keywords: Cracks, Prevention, Remedies, Structure, Types of Cracks.
