When designing cantilevered glass balustrades, civil engineers typically consider factors such as structural integrity, load-bearing capacity, wind load, safety, building code compliance, and cost. They also consider the aesthetic and architectural design of the balustrade, as well as any potential maintenance or repair requirements. Engineers also use software to help design and validate the structure. In addition, they may consult with other engineers, architects, and building code officials to ensure that the design meets all necessary requirements.
