7. Questions???Are you losing work to metal buildings? What kind of projects?

8. Why Worry About Competing? • MBMA claims about 60% market penetration • That is to say 6 out of 10 non high rise buildings • However, they often do not utilize metal wall panels (Competition is a metal wall) • So are ready mix companies really vendors or competitors?

9. The Answer Is ? • You must be both!! • Vendor for foundation and slab concrete. • Possible supplier for wall panels on some hybrid jobs. • But often a competitor when teamed with conventional roof supplier.

10. Tilt-Up Panels are a Hybrid ProductThat is, they may be used with either metal buildings or conventional buildings.

11. Definitions:Pre-engineered Building is a steel framing system, usually with a metal roof and walls, with all structural engineering done by a manufacturer.Conventional Building is a framing system, built of any material, with the structural engineering done independently of the manufacturer.Also, the distribution systems of the two approaches are different.

12. Is this building a metal building or a conventional building?

14. For Tilt-up to Be Competitive with Metal Buildings - A Broad View of Building Construction is Necessary! A narrow product view, i.e. comparing only metal wall cost to tilt-up wall cost in-place, will always indicate metal walls are the choice, but this hardly the story. Don’t fall into this trap!

15. History and Trends in Metal BuildingsNeed to Understand Your Competition.What are their Strengths and Weaknesses?

16. Historical Background - Metal Buildings • Metal building companies first formed in 1920’s to service oil industry, • WW II saw the development of the Quonset Hut, and • The Quonset Hut was a major image problem for the PEMB industry .

17. Historical Background - Metal Buildings (cont.) • The introduction of high strength sheet steel and the SSR roof in the 1960’s propelled the industry into a fast growth period in the 1970’s and 1980’s and • The PEMB industry relies heavily on proprietary computer software to aggressively design their products,

18. Historical Background - Metal Buildings (cont.) • They are very efficient, but don’t have any “extra” steel or strength and • The AISC now (since the early 1990’s) certifies PEMB companies to ensure a minimum level of quality.

19. PEMB Trends in the 1990’s • PEMB structures have continued to increase their market penetration, PEMB are attempting to compete for complex buildings and • This has lead to a misuse of PEMB structures and actually higher prices and longer deliveries than conventional construction--however owners often have no way to know this.

20. Example of a More Successful PEMB Market Penetration Program • Hardwall Systems (concrete or masonry walls). • Tingle, Lee’s Summit, Missouri

21. Typical NEW PEMB Hardwall Buildings • Designed for strict serviceability issues • Load bearing walls

22. History and Trends in Conventional ConstructionStrengths and Weaknesses of Conventional Approaches.

23. Trends in Conventional Construction • Wide spread use of high strength steel, • Increased use of tubular steel, • Previous points driven by the rise of the mini-mill, • Continued shortages of WF shapes, and • Precast concrete wall industry is generally in decline, but is being replaced by site-cast panels.

24. Historical Background - Conventional Buildings • Conventional Building carry on the trend of “stick built” construction, • Architects and engineers have always done the bulk of the design work, and • Steel framing is the most common, but pre-cast concrete and cast-in-place concrete are sometimes used in special low-rise buildings.

25. Trends in Conventional Construction (cont.) • CMU use is very influenced by local building trades, • The overall trend is to “pre-engineered” more components, example is the steel stud industry and wood Truss-Joist products, and • The good architect/engineer takes advantage of these trends for his client.

26. Historical Background - Conventional Buildings (cont.) • Wood framing and steel stud framing are still very common in smaller structures, • The conventional building world has been slower to adopt the more efficient methods used in the PEMB industry, • High strength steels have only become the norm in the last 5-10 years, and • The steel joist industry and pre-fabricated wood trusses have adopted PEMB style methods.

27. Trends in Conventional Construction (cont.) • Bar joist industry claims they are involved in over two thirds of low-rise construction, and • How can this be true with PEMB market share at 65% in the late 90’s???

28. Big Question - How Do You Make Tilt-up Competitive with Metal Buildings (really metal walls)? • Must find and team with partners. • Partners can be a metal building company or local dealer. • They can be a joist supplier (SMI is a good example). • They can be a developer or architect. • In all cases, develop a market sense of where your opportunities exist.

29. Basic Cost Examples (100’x200’x20’ and 200’x400’x20’) • 20,000sf MB, metal walls convert to $2.09/s.f. • 20,000sf TU, concrete walls convert to $4.14/s.f. • 80,000sf MB, metal walls convert to $1.02/s.f. • 80,000sf TU, concrete walls convert to $1.88/s.f. • Conclusion - All other things being equal, bigger is more competitive.

30. Basic Design Concepts(These will make the previous unit costs even closer, and even eliminate the cost disadvantage) • Eliminate perimeter columns (tough for metal building types!) tilt-up walls are very strong, use them. • Use long bays over 30 feet (bar joists are a very low price levels). • Consider and sell alternatives to SSR roofing..currently a big advantage. • SSR/bracing diaphragm installed is $3.30/s.f. • Single Ply/Deck installed installed is $2.20/s.f.

31. Example: (This 90,000 s.f. project was essentially conventional except for roofing, and SSR was more costly than single ply and deck. Also exterior columns were not necessary).

32. Industry Legend:Metal buildings are less costly than conventional.Not true at least for structures over about 40,000 s.f.

33. Avoid long clear-spans, competing only with walls. Avoid tall buildings, panel costs may rapidly escalate over about 30 foot tall. Avoid small projects unless they are “jewel-boxes” where cost is not an object. Avoid low quality jobs, tilt-up is several steps up the quality ladder over metal walls. Avoid projects not well suited for tilt-up

34. Contrary Example: (This 250,000 sf industrial project still used a combined tilt-up grade beam and wainscot wall, despite being in the low quality, span and height avoidance groups.

35. Butler Delta Joist and Hardwall Systems Ceco/Star ABC Hardwall NCI Group’s new Long Bay product Varco-Pruden The problem working with these companies is almost always their“mind-set”. Also, the interface between the panels and their products is a problem on most jobs. Another Approach - Join with Metal Building Companies

36. When competing with metal walls, or promoting tilt-up construction on any job, you need: • ARMCA and TCA marketing support. • Clearly explain the advantages of tilt-up. • Team-up with other quality sub-contractors, vendors and suppliers. • Qualify users, do not waste time on “low-cost, tire-kickers”.

37. Marketing Needs: • Technical literature to influence and train engineers. • Sales literature for owners. • Training for contractors (TCA Certification). • Seminars in your area.

38. Review The Advantages: • Very Durable, i.e. quality is big advantage over metal. • Flexible and attractive, remember arches, curves, reveals, inlays, and many other architectural features are possible, try this in metal. • Secure, metal walls can be removed with simple hand tools. • Long-Term Value, Lenders perceive concrete walls as having much better long term value over metal.
