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

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

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

10 Tilt-Up Panels are a Hybrid Product That 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?

13 Tingle Project is an American Building Company Project

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. Dont fall into this trap!

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

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

17 Historical Background - Metal Buildings (cont.)

19 PEMB Trends in the 1990s PEMB structures have continued to increase their market penetration, PEMB are attempting to compete for complex buildings andPEMB 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.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.

22 History and Trends in Conventional Construction Strengths and Weaknesses of Conventional Approaches.

23 Trends in Conventional Construction Wide spread use of high strength steel,Wide spread use of high strength steel, Increased use of tubular steel,Increased use of tubular steel, Previous points driven by the rise of the mini-mill,Previous points driven by the rise of the mini-mill, Continued shortages of WF shapes, andContinued shortages of WF shapes, and Precast concrete wall industry is generally in decline, but is being replaced by site-cast panels.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,Conventional Building carry on the trend of stick built construction, Architects and engineers have always done the bulk of the design work, andArchitects 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.Steel framing is the most common, but pre-cast concrete and cast-in-place concrete are sometimes used in special low-rise buildings.

28 Big Question - How Do You Make Tilt-up Competitive with Metal Buildings (really metal walls)? Must find and team with partners.Must find and team with partners.

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.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).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.Consider and sell alternatives to SSR roofing..currently a big advantage. SSR/bracing diaphragm installed is $3.30/s.f.SSR/bracing diaphragm installed is $3.30/s.f. Single Ply/Deck installed installed is $2.20/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 projects not well suited for tilt-up Avoid long clear- spans, competing only with walls.Avoid long clear- spans, competing only with walls. Avoid tall buildings, panel costs may rapidly escalate over about 30 foot tall.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.

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 Another Approach - Join with Metal Building Companies Butler Delta Joist and Hardwall SystemsButler Delta Joist and Hardwall Systems Ceco/StarCeco/Star ABC HardwallABC Hardwall NCI Groups new Long Bay productNCI Groups new Long Bay product Varco-PrudenVarco-Pruden The problem working with these companies is almost always theirmind-set. Also, the interface between the panels and their products is a problem on most jobs.

36 When competing with metal walls, or promoting tilt-up construction on any job, you need: ARMCA and TCA marketing support.ARMCA and TCA marketing support.
