Stop the presses? No at least not when additions are made to a tilt-up building. When Democrat Printing and Lithographing Company decided that it needed to build a new plant, it made ease of expansion one of its prime design requirements. Because of the company's rapid growth, their new building would have to possess an almost organic capacity for growth. A tilt-up concrete structure, it was determined, would go farthest among design alternatives toward satisfying all of Democrat's needs.
Six years after occupying the new building, the company was ready for its first expansion. It was at this time that the real benefits of tilt-up construction paid off. Design work and construction for the addition were straightforward, having been anticipated in the original plans. New material needs were minimal and demolition costs nonexistent. Best of all, ongoing printing operations within the plant did not have to shut down for one minute.
A sequence of production was arranged to leave the original building intact during most of the construction. Workmen placed the foundations for the new walls and laid the granular subbase and 10-inch-thick reinforced concrete floor, as well as the structurally isolated 20-foot-deep reinforced concrete piles and 2 «-foot-thick foundations for the presses, cast the tilt-up panels and erected the structural steel framework for the addition all this was done before the original structure was touched. At the same time, within the building a temporary wall of «-inch-plywood was erected, running within a few feet of the wall that was to be eliminated. Covered with plastic sheeting, the plywood provided printing operations with good protection against rain once the rear concrete wall was removed. Scheduling the work during the mild and dry autumn months further reduced the effects of weather.
