How does tilt-up compare in cost with other types of walls?
Very favorably. Costs will depend on local conditions, but the construction experience of MacKinnon-Parker, of Toledo, Ohio may be helpful. On a 230,000-foot addition to an existing plant they completed the construction, including paving, shipping and receiving docks, two-story interior offices, electrical system, make-up-air facilities and other incidentals for $6.05 per square foot, which was $100,000 less than a bid for a building of uninsulated protected metal siding. On other warehouses built by the same company cost analyses showed the decorative panels used to be considerably less expensive than concrete masonry. On one 150,000 square-foot warehouse the saving was $20,000. Tilt-up is also less expensive than brick. In addition to costs being lower, tilt-up walls have many advantages. They are more resistant than other walls to impact from trucks and forklifts. They are less likely to undergo shrinkage cracking than concrete masonry. When an addition is made they can be demounted and reused in a new location. A two-hour fire rating can be obtained with a five-inch wall, good thermal characteristics can be obtained, and maintenance painting is unnecessary.
