Placement of cast-in-place concrete pipe (CIPP) in a typical metropolitan area like Phoenix has doubled in each of the past three years. To cope with this growth and to encourage and accommodate future demand for cast-in-place pipe, one of the principal developers in the field has set up a CIPP franchise plan. Concrete Construction asked secretary and marketing director of Lomar Corporation, Santa Ana, California about CIPP and the firm's franchise system.
Q. Let's define the product first. What is cast-in-place pipe? A. The American concrete Institute Committee 346 report answers that. It's "an underground, continuous nonreinforced concrete conduit having no joints or seams except as necessitated by construction requirements. . . . The pipe is constructed in a previously excavated trench which has a semicircular bottom and vertical or near-vertical side walls. . . . The outside lower portion of the pipe is formed by the trench and the corresponding inside is formed by a specially designed slipform commonly called a boat or sled. . .. The inside. . . is formed either by metal forms or an inflated tube especially built for the purpose."
Q. Why should a contractor be interested in placing CIPP? A. Because he can put it in at lower cost than the equivalent in RCP, and therefore his potential for profit is greater. Q. And your franchise system gives him a shot at those profits? A. Right. We want to make the right contractor very successful because his success will help expand the market for our CIPP system. Q. The range of sizes, with separate machines and forms for each size, must represent a formidable capital outlay. Isn't that a deterrent to a prospective licensee? A. That's exactly why we're not selling equipment under our plan. We want to make franchising as easy as possible, with as little capital outlay as possible, so we lease or rent out our equipment. We have enough machines of each size to supply our franchisees.
