Buildings, as artificial edifices primarily intended for shelter, exhibit diverse dimensions, contours, configurations, and functionalities. Varied structures serve singular purposes, while others accommodate multiple functions, encompassing both residential and commercial utilities, thereby being categorized as mixed-use buildings. However, a significant predicament inherent in these structures pertains to security vulnerabilities emanating from deficient design practices. Such shortcomings render them susceptible to potential threats posed by both terrorist activities and criminal acts, given the distinctive attributes of these buildings and their utilization. Exploiting the substantial assets housed within, these malevolent actors exploit the apparent vulnerabilities. This research endeavors to evaluate the efficacy of passive security design measures within mixed-use buildings.
The study adopts a qualitative research approach, involving random sampling of buildings from a designated population. The selection criteria encompass structures featuring three or more substantial functions, including residential, commercial, retail, institutional, recreational, and hotel applications. Data acquisition ensues via personal observations, subsequently subjected to meticulous analysis. The findings are presented through tabular and graphical formats employing Microsoft Office tools. The study highlights pivotal passive security facets for consideration in mixed-use building design, encompassing standoff distance, incorporation of on-site passive security elements, as well as access and parking provisions.
The investigation underscores that a significant proportion—70%—of the sampled mixed-use buildings in Offa exhibit inadequacies in incorporating passive security measures during the design phase. A noteworthy contribution of this thesis lies in elucidating the necessity of maintaining a distinct gap of 1200 millimeters between adjacent security barriers, towering at a minimum elevation of 600 millimeters to optimize security design. Consequently, it is recommended that the integration of passive security measures, encompassing optimal spacing between structures, utilization of carbon-reinforced polymer for wall cladding, deployment of perimeter fencing, cultivation of defensive plantings, application of laminated safety exterior glass, alongside the implementation of chicane and offset road approaches, be an intrinsic facet of the design stage. This approach will invariably safeguard both human lives and valuable assets.
