By September 1962, the Landmark tower was nearing completion and had become the tallest building in Las Vegas and the state, being visible from 20 miles away. By that time, many stores in the Landmark Plaza had closed due to falling debris that included welding sparks, steel, tools, rivets, and cement. A construction delay occurred in September 1962, when shipments of steel for the tower's dome were deemed inadequate and crews had to wait for new shipments. Construction was progressing rapidly on the tower's dome during October 1962, with steel and concrete still being added to the tower. Completion was still scheduled for early 1963. The Aluminium Division of Apex Steel Corporation Limited was contracted to install a $40,000 aluminum undershine on the tower's dome, to provide a maintenance-free and clean-looking appearance for viewers on the ground. Crews used scaffolding and hoists to reach the area where aluminum sheets needed to be placed. Each day, it took crews 18 minutes to be lifted up. Due to delays arising from strong winds, it took crews two months for the aluminium to be attached.
