MBMA MISSION

It is the mission of the Metal

Building Manufacturers Association

(MBMA) to advance the collective

interests of the metal building

systems industry.

ABOUT MBMA

MBMA has served metal

building systems manufacturers

and suppliers for 56 years.

Its membership represents

more than $ 2 billion in annual

steel shipments and accounts

for approximately 49% of the

total non-residential low-rise

construction market in the

United States. MBMA provides

engineering leadership through

the many research programs

that it sponsors annually, often

in coordination with major

universities and engineering

schools throughout North America.

This research is used to improve

the performance, efciency and

quality of metal building systems,

to elevate the technology used

to produce them and to promote

the expanded use and collective

interest of the metal building

system industry.

The metal building industry has weathered the recent

recession and come out stronger, thanks in part

to the efforts of the Metal Building Manufacturers

Association. The research and technical work that

the association does, in hand with a commitment

to education and communication, has helped the

industry grow even when times were tough.

Data collected under the guidance of MBMA’s

Statistics Committee shows that through the rst

three quarters of 2012, domestic building shipments

were the best in four years. MBMA members

reported that:

• Shipment revenues were 7.41% percent higher

than in 2011;

• Tons of steel shipped were up 5.75 % during

the same period.

Metal buildings continue to gain market share as

owners and speciers see the cost effectiveness,

energy efciency, and sustainable benets of metal

building systems.

Driving these trends is the excellent work

accomplished by MBMA members and committee

volunteers. For example, MBMA’s Energy and

Sustainability Committees are educating buyers and

speciers about the green traits of metal buildings.

Just as importantly, both of these committees are

addressing the myriad codes and standards that

address green or sustainable buildings. These

committees are making sure that MBMA has a voice

in the writing of standards, and that, once adopted,

the information contained in the standards is

disseminated to the MBMA members. They, in turn,

share this knowledge with builders across America.

The Fire and Related Insurance Matters Committee

is also working hard to ensure that metal buildings

are treated fairly by code writers and enforcers. The

technical staff and members of the committee

have tested several new wall assemblies over

the past several years and have successfully come

away with new UL one- and two-hour re ratings.

These rated assemblies enable metal building

system manufacturers to penetrate additional

markets where such ratings are required, helping to

further advance the growth of the industry.

The Technical Committee has undertaken a range

of research projects in recent years that help

engineers, designers, and buyers better understand

how metal buildings and components perform. One

example of MBMA’s leadership is in the study of

the behavior of metal buildings under earthquake

loading. This effort has been underway for

several years and will lead to the code adoption of

appropriate design methodology that will make metal

buildings more economic in high seismic areas.

And nally, the 2012 Metal Building Systems Manual

was released toward the end of 2012. Since the

rst edition was published in 1959, this nationally

recognized reference manual has been the primary

resource for the metal building industry

for building owners, manufacturers,

general contractors, erectors,

engineers, architects, speciers,

inspectors, and other building

professionals.

MBMA is managed by Thomas Associates

Inc, one of the oldest and largest association

management rms in the United States. It

has an extensive and diverse technical team

that can support the code, standards, and

research goals of its various associations.

Such synergy allows it to expand research

capabilities and bring in human resources

that enhance the technical strength of MBMA.

The Metal Building Manufacturers Association is proud to

be a driving force in the growth and acceptance of metal

building systems in the low-rise, non-residential construction

market—a position it has retained since MBMA was founded

in 1956. Consistent, sophisticated technical capability

and relevant research, combined with unique educational

resources, have positioned the organization and its members

as industry change-makers—a role it will continue to play into

the ever-evolving future.

MBMA CONTINUES EXPANDING ITS LEADERSHIP ROLE

Charles Stockinger, MBMA General Manager

GENERAL

MANAGER’S

PERSPECTIVE

MBMA’s strength is exemplied through a range of

actions and undertakings which are laid out each year

in our strategic plan. Our many technical research

programs are performed in partnership with major

research universities and national laboratories such as

the Oak Ridge National Laboratory (ORNL). These lead

to improvements in the performance of metal building

systems.

The 2012 MBMA Annual Meeting took place at the

Dallas/Fort Worth International Airport at the end of the

year with almost 100 attendees from 17 Metal Building

Systems Member companies and 33 Associate Member

companies. The attendees heard presentations from all

of the MBMA technical committee chairs. This annual

report highlights many of the signicant accomplishments

described in their individual reports and provides

forward-thinking detail about what their committees

intend to achieve in 2013 and beyond.

We extend our thanks to the committee chairs and

the committee members for all of the time and work

they invest to make this organization what it is today.

In particular, we would like to extend our thanks to

several outgoing committee chairs for their hard work

and dedication. They are: Fred Koetting, MBMA’s 2012

Chairman, and Dave Evers, who served as Chairman of

the Energy Committee for a number of years.

Hundreds of meetings and thousands of hours go

into every technical accomplishment we achieve. We

certainly couldn’t do it without the expertise and input

of brilliant individuals in our member companies as they

share their knowledge and skill for the betterment of the

industry.

We would also like to take this opportunity to

acknowledge the excellent work that MBMA’s

professional staff successfully undertook throughout the

year. The MBMA leadership, supported by the Thomas

Associates’ team, continues to drive the association

forward through their hard work, technical

expertise, and commitment to excellence.

MBMA is also involved with other organizations that help it to

have a say in the process of code changes and updates. MBMA

continues to be part of the Cool Metal Roong Coalition that

represents metal roong at various codes and standards meetings,

such as California Energy Code, Cool Roof Rating Council, and

Energy Star

In 2012, MBMA continued its participation in the National

Association of State Energy Ofcials (NASEO) as an afliate

member. This group is funded by the DOE and the states. It holds

a variety of regular conference calls, webinars, and meetings

throughout the year aimed at the education of state code ofcials

and it promotes the adoption and enforcement of the IECC. We

continue to participate in related conference calls. These offer

us the opportunity to not only stay in touch with the state level

code activities but also give MBMA an opportunity for training and

education of state ofcials regarding metal building systems and

their energy code compliance options.

Another factor that affects everyone in the construction industry

is the wide variety of acceptance of new codes and standards.

A quick look at where states are in adopting the most recent

standards shows a range of implementation, with some states and

territories already implementing the 2012 IEC and ASHRAE 90.1

– 2010. Going forward, the Energy Committee will keep MBMA’s

voice strong in both the development and implementation of these

standards.

Education and Training

The Energy Design Guide for Metal

Building Systems was released in

2010 and is available through the

MBMA online bookstore (www.mbma.

com/bookstore). It is an important

resource for anyone who works with

metal building systems; but with

the release of new codes since its

publication, it requires review and

Energy Committee Mission

To promote the use of metal building systems in the non-

residential construction industry, by encouraging fair and

equitable treatment of metal building systems by energy

codes, standards organizations, testing and rating groups,

and other governmental and non-governmental groups.

The Energy Committee is focused on three specic areas:

• Energy Codes and Standards

• Education and Training

• Research and Innovation

Energy Codes and Standards

The MBMA Energy Committee is working to bring a

semblance of order to the changing and broad range of

codes and standards for members and those who work

with metal buildings. MBMA is serving on committees and

monitoring the activities of ASHRAE, ASTM E60, California

Title 24, and IECC. Under the Sustainability Committee,

MBMA is monitoring high performance standards and

codes such as ASHRAE 189.1 and the IgCC.

While the 2012 International Energy Conservation Code,

or IECC, is now in place, other codes and standards are

being continually rewritten and updated. This past year,

most of the committee’s activity has focused on revisions

to the ASHRAE standard. ASHRAE 90.1-2010 has been

published and initial changes for the 2013 version are

now being considered. Addenda have been proposed

that can impact the requirements and prescriptive

assemblies for metal buildings. In addition to the ASHRAE

updates, MBMA participated in the revisions to the 2013

California Title 24 Code by reviewing and commenting

on several items. We expect more changes in daylighting

requirements, lighting controls, fenestration, and cool

roofs for California and less attention to building envelope

insulation requirements.

COMMITTEE ACHIEVEMENTS

updating. The committee will

lead the effort for this task in the

coming year.

The Energy Code Compliance

for Metal Building Systems

Webinar program has been in

place since 2011. In 2012, there

were 10 well-attended webinars

offered throughout the year.

The Energy Committee will

continue to run these webinars

in 2013, updating and revising them to offer continuous

improvements.

A seminar entitled Energy Code Compliance Toolkit for

Metal Building Systems was held on January 16-17, 2012.

This program offered an introduction to various code

compliance paths with emphasis on using ComCheck

software, a free program provided by DOE that can

be used in 45 states for energy code compliance. This

seminar was designed to also “train the trainer” to enable

member companies to begin providing training to their

builders and contractors. Comprehensive materials were

provided to participants for their use as trainers. Energy

code training was subsequently initiated throughout

MBMA Building System Member companies.

Energy Committee Research and Innovation

There are two specic research projects on which the

committee is focused:

1. The Flexible Research Platform being developed at the

Oak Ridge National Laboratory (ORNL) and Assembly Air

Inltration Testing. ORNL’s Flexible Research Platform is

a multi-year project started in 2011 that uses a 40 ft. x 60

ft. metal building as the exible platform. The building was

recently completed, and a test plan has been formulated.

The project goal is to evaluate the actual performance

of the building and establish cost-effective building

designs that have a signicant impact on the total energy

consumption. Testing will begin in 2013.

2. The Air Inltration Task Group was established to

evaluate the air-inltration performance of metal buildings

and explore ways to make improvements. Continuing its

successful work from 2011, the task group tested several

discontinuities in metal buildings, including corners,

eaves, ridges, and gable ends. The base tests were

constructed of details typically used in these elements,

and alternate designs were tested to evaluate the impact

of modifying certain details. The tests indicate that there

are reasonable and cost-effective opportunities to improve

the performance of these details. We are analyzing the

results and will provide a written report in 2013.

Sustainability Committee Mission:

The MBMA Sustainability Committee was formed in 2009 to

represent the metal building industry in the many facets of green

and sustainable construction and to ensure fair and equitable

treatment for metal buildings by the many groups which publish

standards relating to green construction.

2012 Overview

The MBMA Sustainability Committee has focused on very specic

undertakings through its two task groups in 2012, while being

guided by its broader mission and objectives. The overarching

goals include:

• Positioning metal buildings as a premier green

construction alternative;

• Educating the MBMA membership in sustainability;

• Leveraging the metal building industry through AISI’s

sustainability efforts; and

• Working with other industry groups.

The High Performance Green Building Task Group concentrated

its efforts on inuencing and interpreting new sustainable codes,

while the Life Cycle Inventory/Life Cycle Assessment (LCI/LCA)

Task Group has been collecting and reviewing the data used in

Athena life cycle assessment tools.

High Performance Green Building Task Group

The High Performance Green Building Task Group oversees and

seeks to inuence the development of green and sustainable

codes and standards. Over the course of the year, this group

commented on LEED v4, the International Green Construction

Code (IgCC), ASTM Standard Practices, and ASHRAE 189.1.

There were a number of important developments in these codes

that could affect metal buildings in the future. As it now stands,

LEED v4, which is due out in June, 2013 would permit initial

values of SRI (Solar Reectance Index) in addition to 3 year

aged values. Since steel far out-performs other roong materials

as they age, this could potentially penalize buildings that use

metal roofs. The task force also addressed inequities for steel in

several areas and commented on improving clarity in LCA results

and Environmental Product Declarations (EPDs). Eventually, the

goal is to see industry-wide EPDs for metal buildings.

For the IgCC, the task force collected comments from committee

members as well as both the AISI and the CMRC and is now

coordinating comments with the AISI. The ICC delayed the new

version by a year and the commenting process will continue

in 2013, with code change proposals due in January, 2014.

ASHRAE 189.1 will update in 2014 and new proposals are

expected. The task group is working with the entire committee to

develop commentary for the whole building LCA standard in the

ASTM Standard Practices.

In 2013, the task group will disseminate information about

LEED v4 when it is released and continue to gather and review

comments and information for the upcoming versions of IgCC,

ASHRAE 189.1 and the ASTM Standard Practices.

Life Cycle Inventory/Life Cycle Assessment Task Group

The Life Cycle Inventory/Life Cycle Assessment (LCI/LCA) Task

Group has a primary objective of driving LCA data for metal

building assemblies into the appropriate tools to support member

companies in meeting the requirements of green building codes

and standards.

Two major LCA tools, Athena’s EcoCalculator and Impact

Estimator, have been developed by the Athena Sustainable

Materials Institute and its software partner, Morrison Hersheld.

Both are now available for free download, making LCA use easier

and more widespread. A number of building codes and standards

now have LCA options, including LEED 4.0, ASHRAE 189.1, and

the IgCC. Ensuring that the data for metal buildings is accurate

and up-to-date is a very important function of this group.

In the rst half of the year, the LCI/LCA Task Group accumulated

and reviewed the LCI plant data for metal building manufacturers

that was submitted to Athena. Later in the year, the group

reviewed and commented on the draft report, assisted Athena in

addressing peer reviewed comments and, in November, accepted

the nal report.

In the coming year, the task group will work with Athena and

Morrison Hersheld to develop a benchmark tool and the Metal

Building Solution for Impact Estimator. It will have an algorithm

that will accept loading and geometry data and convert the

impacts from a per-ton basis to a per-square-foot-of-assembly

basis. This tool is pivotal to completing the inclusion of metal

building systems into the Impact Estimator and ecoCalculator. The

committee will conduct special member educational programs

once the program tools are nalized.

SUSTAINABILITY COMMITTEE

Brad Robeson,

Committee Chairman

Committee on Fire Protection & Related Insurance Matters’

Mission:

To promote the use of metal building systems in the non-

residential construction industry by encouraging fair and

equitable treatment of metal building systems by regulators, re

and building codes, insurance and insurance regulating and

rating organizations, underwriters, and re-insurance rms.

2012 Overview

The Fire Protection & Related Insurance Matters Committee once

again had a busy year as it continues to address re prevention

and insurance issues while educating MBMA members and the

public-at-large about these areas. The committee oversaw the

re protection webinar programs, the MBMA Insurance Study,

and completion of a new 2-hour, re-resistive wall assembly.

Fire Protection Webinars

Fire Protection webinars were introduced in 2011 and they

continued in 2012. The committee will carry forward the webinars

into 2013, while revising them with appropriate updates and

improvements. Paid attendance in the webinar entitles the buyer

to a copy of the Fire Resistance Design Guide for Metal Building

Systems, a valuable resource for anyone involved with metal

buildings. In addition to the two public webinars, a presentation

was made to a member rm’s builder group.

MBMA Insurance Study

The MBMA Insurance Study is a multi-year, multi-step project

that is nearing completion. The committee is also updating the

MBMA Insurance Fact Book and Insurance Bulletins. Once

these have been revised, then they will be promoted through

educational programs and news items.

1- and 2-hour Fire-Rated Wall Assemblies

The 1-hour re-rated wall assembly was completed in 2011 with

the release of UL Listing W404. The information on this assembly

was detailed in Fire Resistance Bulletin #5 and is available

for free download at www.mbma.com. In 2012, the committee

focused its efforts on a 2-hour re-rated wall assembly. This

assembly was tested at Underwriters Laboratories in June, 2012

and was a success, resulting in a new listing, UL W413.

Both the 1- and 2-hour re-rated assemblies are metal building

friendly and have the following features:

• Can be installed after metal building erection

• Can be used for retro-t

• Ratings achieved from both sides of the wall

• Uses conventional drywall assembly

• Energy compliant with plenty of insulation in the walls

The 2-hour re-rated wall assembly has some additional

features and allows market penetration where 2-hour re ratings

are required for factory, mercantile, and storage areas with 5

feet or less of separation. It also provides potential for market

penetration for buildings that are classied as Type H Hazard

Occupancies.

In 2013, the committee is focused on moving forward with all

of these projects. In addition to continuing the re protection

webinars and nishing the Insurance Study, additional work is

planned for the 2-hour re assembly. The details of UL W413

will be spelled out in a new Fire Resistance Bulletin and this

information will be brought to members and the public via the

MBMA website, trade magazines, shows, and training. The

committee also plans additional work on 2-hour assemblies with

some variations on the initial design.

COMMITTEE ON

FIRE PROTECTION &

RELATED INSURANCE

MATTERS

Bob Hodges,

Committee Chairman

Safety Committee Mission:

MBMA’s Safety Committee was put in place

to provide a mechanism to share ideas

and principles in safety which relate to the

metal building industry, build collaborative

relationships between MBMA Member

companies and Associate Members, and

establish the metal building industry as a leader

in safety.

By focusing on safety and best practices,

member companies will see specic, tangible

results including:

• Reductions in company operating costs

due to a safer working environment;

• Fewer lost work days and restricted duty

assignments;

• Less exposure in OSHA audits; and

• Reduced insurance premiums at renewal.

Additionally, companies with good safety

practices will see improvements in employee

morale and ultimately increased prots.

MBMA’s Safety Principles

• All injuries and work-related illness can be

prevented.

• Leadership is responsible for clear safety

objectives. All employees are responsible

and accountable for working safely.

• Employee engagement and training is

essential.

• Working safely is a condition of

employment.

• Excellence in safety and health drives

excellent business results.

• Safety and health is integrated into all

business management processes.

2012 Safety Committee Overview

The MBMA Safety Committee held its annual

meeting in Salt Lake City, Utah in August. This

event was well attended and included a series

of roundtable discussions on best practices in

safety, practical presentations on a variety of

safety subjects, and testimonials from people

who have been affected by safety-related

incidents. Specic presentations included:

• Incident Reporting

• OSHA’s Voluntary Protection Program

• Safety Resource Sites

• Welding PPE

• Electrical Arc Flash

• Summer Safety initiatives for new hires

• The New Global Harmonization System,

or GHS, Hazard Communication

Program

In addition to its annual meeting, the Safety

Committee developed a Safety Leadership

team to share committee initiatives and to

provide future committee leadership. It also

increased utilization of the MBMA Safety

website by MBMA member companies and put

in place a series of free safety webinars for

member rms.

Lunch and Learn Webinars

In 2012, the committee also established a

series of Lunch and Learn Safety webinars.

Three webinars were conducted in the fall of

2012 on Fall Protection, Safety Leadership,

and Vehicle Safety. A large number of MBMA

members and others participated in each

of these webinars. The committee plans to

continue these valuable, free learning sessions

with additional topics planned for 2013.

MBMA Safety Awards

Safety performance awards were presented

in May of 2012 at MBMA’s Spring Meeting.

Forty-six manufacturing facilities submitted

data for the safety awards. A total of 53 safety

awards were presented with some facilities

winning multiple awards. Seventeen individual

plants won Superior Overall Safety Record

awards, 33 plants won Improved Safety awards

for lowering injury frequency rates by at least

20%, and three plant locations received Safety

awards for No Recordable Cases in 2011.

2013 Initiatives

The annual Safety Committee Meeting will

take place in Atlanta, GA in May of 2013.

The committee is encouraging each MBMA

member company to send designated safety

representatives, front line management, and

plant safety personnel.

• The committee’s leadership is

developing an agenda which is

compact, allows for team building

and interaction, and will be cost-

effective so companies will see value in

sending multiple representatives.

• If representatives cannot attend, we are

encouraging participation via

GoToMeetings, web casts, and

conference calls.

• In addition to Metal Building System

Members, we are working with Associate

Members to send safety representatives

to the annual meeting so that we can

continue to get different views and ideas

on safety related issues.

The committee is also focused on several

specic tools and areas for safety. The

Global Harmonization System, or GHS, was

introduced at the 2012 Safety Meeting and

will transition in over the next three years. The

rst deadline is December 1, 2013 and the

remaining steps need to be complete by June,

2016. Additionally, welding shop air quality will

continue to be examined and we will be looking

into options for safety improvement where

needed.

Active participation and utilization of the

MBMA Safety website is another focus. We

encourage member companies to submit

safety information for the MBMA website

that can be shared by all MBMA

member rms.

SAFETY COMMITTEE

Stanley Reid,

Committee Chairman

TECHNICAL COMMITTEE

The MBMA Technical Committee serves a vital role

within MBMA and also serves the industry as a whole.

It keeps MBMA and its members at the forefront of

technological challenges within the industry. The

committee continues to engage in research projects

in coordination with national research universities

and oversees the publication of MBMA manuals and

guides.

In 2012, the committee oversaw the release of two

updated technical guides: the second edition of

The Metal Roong Systems Design Manual and the

2012 Metal Building Systems Manual. In addition to

these manuals and the projects detailed below, the

committee also worked to improve and update several

codes, including the wind load provisions in ASCE 7.

2013 RESEARCH PROJECTS

Seismic Behavior of Metal Buildings

The goal of this project is to update the building codes with more appropriate

seismic-design methods for tapered-member rigid frames. This will make metal

buildings more adaptable in high seismic areas as well as ensure the continued

excellent performance associated with earthquake loads. Dr. Chia-Ming Uang

has led this effort that has included full scale shake table testing and cyclic testing

of rafter/column component assemblies. He is now developing the appropriate

seismic performance design factors based on a FEMA method required by the new

seismic codes. The work will be wrapped up in 2013 and MBMA will continue to

work to have the results of this study incorporated into the latest building codes and

standards.

Snow Loads on Roofs with Solar Panels

There has been very little research performed on the effect that solar panels have

on roof snow loads. Our objective is to develop an ASCE 7-consistent guideline for

snow loads atop solar-paneled roofs. The research will investigate:

• The inuence of solar collectors on roof exposure;

• Thermal and slope factors; and

• Drainage and eave ice dam considerations.

This research is being carried out by Dr. Michael O’Rourke of Rensselaer

Polytechnic Institute (RPI).

Wind Loads on Overhead Doors

Work on improving the high wind performance of overhead doors has been under

way for several years in coordination with DASMA, the Door and Access Systems

Manufacturers Association. The objective is to establish recognized design limits

and procedures for metal building jambs supporting roll-up sheet doors (drum

doors). Researchers at Virginia Tech have developed a model to predict door

Gerald Hatch, P.E.,

Committee Chairman

deection given wind pressure, initial wind lock gap, and

jamb exibility. In 2013, the committee expects to nalize

a general procedure that will allow each manufacturer to

address jambs in an economical way.

Limit State Design of Through-Fastened Purlins/Girts

The project goal is to validate and implement an analysis-

based prediction method for through-fastened cold-formed

steel girts and purlins as an alternative to the current

R-factor approach in AISI-S100-07 Section D6.1. Existing

strength-prediction methods are simple but constrained

to empirical bounds. As new energy-efciency rules come

on line and new building materials are developed, the

empirical methods may no longer be valid. Providing a

direct strength method, a member-based supplement to

the current prescriptive methods will give designers a less

restrictive methodology. Dr. Cris Moen at Virginia Tech is

the lead investigator for this project.

Shear Strength of Tapered Members

The method that is commonly used to determine shear

strength of tapered members has been around for

decades, based on Omer Blodgett’s book on the design

of welds. The committee’s recent work, carried out by

Dr. Brad Davis at the University of Kentucky, is focused

on testing 12 specimens of varying geometry to obtain

objective test evidence to corroborate the approach.

Testing that was completed in 2011 conrmed that the

modied shear approach is conservative and requires an

updated approach. Work will continue in 2013 to extend

the concept to prismatic as well as tapered members.

Flange Brace Research

The objective of this research is to determine ange-brace

strength and stiffness requirements that preclude stability

buckling of tapered member frames. Researchers at

Georgia Tech have been studying ange-brace strength

and stiffness requirements for several years and have

demonstrated that the strength and stiffness requirements

for ange braces used in metal building systems are

different than those developed for conventional steel

construction. Dr. Donald White is now developing

a ange-brace tool that will allow metal building

manufacturers to generate rules for the strength and

stiffness requirements of ange braces, and ultimately be

able to interface with production design programs.

Base Plate Wizard

Recent lateral drift measurement of a metal building and

seismic behavior testing have shown that frame base

stiffness has a larger-than-anticipated impact on design.

Dr. Finley Charney at Virginia Tech has developed a

prototype base plate wizard that can be used to determine

the stiffness of frame base plates in metal building

systems. This input can then be used in the analysis

and design of rigid frames to achieve a more accurate

assessment of the lateral drift. A nal version of the base

plate wizard is expected in 2013.

Resources

The committee is reviewing and revising several

publications in 2013 in coordination with other MBMA

committees. Supplements are planned for the Energy

Design Guide, Fire Resistance Design Guide, and the

Seismic Design Guide. A new compilation is planned for

the ASTM Standards. The committee is also working on

an Inspection Handbook and is advising an independent

expert who is authoring a Foundation Design Manual.

ACCREDITATION COMMITTEE

MBMA’s Accreditation Committee, chaired

by Chuck Haslebacher, serves as the

expert accreditation advocate for the

industry and works with IAS to achieve

solutions that meet the needs of IAS

and the metal building systems industry.

In 2012, the committee established an

MBMA Technical Advisory Council that will

meet with IAS and accredited inspection

agencies to review the AC472 program

and recommend improvements. The

council conducted a survey of all board

members to receive comments, questions,

issues, and ideas related to the AC472

program. Several new programs and

changes are being considered by the

council and IAS, including an international

metal building accreditation program and

the proposed AC473 Component Accreditation Program.

All MBMA Building System Member

companies are accredited in accordance

with the International Accreditation

Service (IAS) AC 472, the IAS

Accreditation Criteria for Inspection

Programs for Manufacturers of Metal

Building Systems. AC472 is the most

comprehensive quality-assurance

accreditation program of its kind and is

designed specically for manufacturers of

metal building systems.

AC472 addresses quality management

system elements such as:

• Personnel requirements;

• Product traceability;

• Process control; and

• Various administrative and technical requirements that are essential

for code ofcials to deem IAS-accredited entities as approved

fabricators.

This comprehensive accreditation program for the inspection of metal

building facilities is based on the requirements of Chapter 17 of the

International Building Code® and provides code ofcials with a means

to approve the inspection programs of manufacturers involved in the

fabrication of metal building systems.

Systems Manual in November of 2012. Since

the manual’s rst publication in 1959, this

nationally recognized reference manual has

been the primary resource for the metal

building industry. It is used by building

owners, manufacturers, general contractors,

erectors, engineers, architects, speciers, inspectors, and

other building professionals.

The 2012 Metal Building Systems Manual provides a practical and

comprehensive resource that helps engineers, building ofcials, and

plan checkers meet the metal building requirements of the 2012

International Building Code

The 2012 edition reects changes in the 2012 IBC and its referenced

ASCE 7-10 standard. The manual also incorporates the results of

research undertaken by MBMA, its member companies, and other

industry groups. Signicant additions and updates include, but are not

limited to, the following:

• The 2010 Supplement to the 2006 Metal Building Systems

Manual has been merged into the body of the 2012 Metal

Building Systems Manual and its appendices.

• Considerable updates were provided in the Design Practice and

Load Application chapter, which provides guidance on the

applications of loads to metal buildings from the 2012

International Building Code and ASCE 7-10 standard.

• The updated Climatological Data by County chapter provides

tabulated wind, seismic, rain, and snow-load data by United

States county based on the 2012 IBC, ASCE 7-10 standard, and

rainfall-intensity loads from the National Oceanic and

Atmospheric Administration (NOAA).

• The Fire Protection chapter includes additional re-rated wall

assemblies recently tested at Underwriters Laboratories, Inc.

(UL) that will provide 1- and 2-hour re-resistance rating of metal

building exterior walls, along with ve new 1-hour, head-of-wall

and continuity joint assemblies.

The 2012 Metal Building System Manual is 724 pages and comes with

a complimentary CD-ROM. The CD includes an electronic version of

the manual along with 58 metal roof AutoCAD details.
