Tilt-up--a method which involves casting concrete wall panels horizontally on top of an already cast floor slab and tilting them into position--is helping concrete make significant inroads against competing materials in the United States and Canada. Concrete contractors not now doing tilt-up work should take a serious look at the opportunities open to them. This article examines some of the markets, explains the basics of the method, and shows you where you can get help in starting and building a tilt-up business. BENEFITS FOR BOTH OWNER AND BUILDER Ease and speed of construction represent a great advantage to the tilt-up owner and builder alike. Other leading advantages of tilt-up construction for the contractor include: simplification or elimination of formwork and scaffolding; adaptability plus flexibility in submitting alternate bids. Benefits for the owner include: varied, aesthetically appealing finishes at reasonable cost; easy expandability as space needs increase; lower maintenance costs due to rugged durability of concrete; lower insurance costs because the structure is noncombustible, termite-proof, and secure; and lower heating and air conditioning costs than for metal buildings. HELP FOR THE BEGINNING TILT-UP CONTRACTOR For the contractor seeking to extend his business into the tilt-up field, there are several ways to get the necessary expert advice and assistance: join your association; become a licensee; find a consultant; attend a seminar or conference; read up on the subject.
