I opened up my business in Texas on July 4, 1987 and have been in continuous operation since then. When I came to Texas about 65 to 70% of the leak issues I dealt with were roof related, now the vast majority of building envelope leaks that I handle are related to the walls and windows. There are a variety of reasons for these problems:
​

1. A very thin workforce and not always well-trained installation crew; most flashing installs are unintentionally done incorrectly.
2. Folks not realizing the absolute long-term cost of improper product selection (chemical incompatibility) or installation.
3. The failure of all involved to not recognize the changing chemical mixtures in today’s wall design.

We all need to realize that today’s walls are being designed for a 40+ year life span and we must adjust our thinking accordingly. Product warranties could be a good indicator of how long the product is anticipated to last. We must also realize that the total installed cost of a flashing system should be taken into serious consideration, and not just the cost of materials. The Brick Institute Association (BIA) has excellent Tech Notes 7 & 7A (Click for link) on this topic at www.gobrick.com/Technical-Notes. This is one of the reference resources I use.

Please remember that for through wall flashing to work properly, the flashing material/assembly must extend beyond the face of the mortar.

Today’s cavity walls are a chemical soup of ingredients:

1. Continuous Insulations: extruded and expanded polystyrene, foil faced polyisocyanurates, spray polyurethane foams and mineral wool.  Some of these materials require a wider cavity wall space to achieve the design effective R-value.
2. Air Barriers: acrylic, silicone, neoprene, polymer sheet goods, polymer modified asphalts and several others.
3. Windows: metal, PVC-coated metal, Kynar-coated (Wikipedia definition: Polyvinylidene fluoride, or polyvinylidene difluoride, (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride), and others
4. Exterior Sheathing materials: plywood, OSB, foil faced board, gypsum boards
5. The chart immediately below is indicative of some of the chemical compatibility problems you could run into. The data is pulled from a variety of manufacturers web sites.
6. The question you need to ask of your suppliers is, “Is your recommended flashing compatible with XYZ cavity wall component?” and get a letter to that effect from each manufacturer that touches another? This is for the protection of both the architect and installer.

​This site wants to Fix Construction. We could debate for years if it’s even broken. But for the sake of positive momentum, let’s say everything can use improvement.
 
Problem:  Labor.

One of the bigger issues we have currently is labor. Or should I say a lack of it. Let’s work on that.  
 
First let’s examine how we got here. If you don’t know where you are at, you will never figure out how to get where you are going.
 
For decades construction has been relegated to second tier citizenship.

• Want to succeed? Go to College! 
• Can’t cut school work? Well, you are probably one of “those people” who should just go out into the “workplace” and not expect much from life. 
• Little Jimmy didn’t score high enough on his Iowa Basics Test? His parents were told the best he could hope for was a “trade’s job” and he’d get by.

So, we have an image problem. Construction work is grunt work.  Dirty, unbecoming grunt work. That’s the message we’ve heard for decades.
 
Who’s Talking?

Think about who is delivering this message. College educated guidance counselors. Our youth and their parents are being given directions to learning institutions by people who came out of, and make their living from - you guessed it - learning institutions.

I don’t blame them for the way they think. It worked for them. There are many, many good white collar professions out there, including architects and engineers. These counselors are trained to see things a certain way, rewarded by school systems who tout their graduation rates and college admission numbers. They are good at their jobs. I do blame them for not presenting both sides of the story to parents who trust and listen to them.
 
The Rest of the Story

There is a second option. Construction provides a better outlet for many who are just not interested in continued schoolwork.  Not everyone is cut out to sit at a desk. There are those who are good with their hands, good with abstract problem solving in real time. Pushing this type of young person to college and deep into college debt often hurts that individual and our economy. How many young people do you know buried in student loans working at the local retail mall?

Our school systems are good at rating the skillsets of our young people. Let’s give them a solid set of options for each type of student.

Part I: Written by Eric D. Lussier - Co-Founder - Let's Fix Construction

A year certainly goes by faster than it used to.  This past year?  Even more so.

One year ago, a spur of the moment conversation with my friend, Cherise Lakeside, spawned my squirrel brain to kick into action.  After discussing the continued ills of the construction industry for seemingly the umpteenth time, something clicked.  We could continue talking about these issues, or, better yet, we could try and correct these issues.  We knew we weren’t the only ones facing hurdles in the office or in the field.  There had to be others.  We had to do something about it.

Three hours later, I presented Cherise with www.LetsFixConstruction.com, complete with its first two blog posts, 'The Fifth C of CSI: Collaboration'  and 'Product Manufacturers: Are You Doing it Right? Construction Education for Product Reps'. In addition to the website I created a Facebook page, a Twitter and Instagram account and an official hashtag: #FixConstruction. 

The concept was simple, share your gripe, but offer positive, left of center solutions to the problem at hand.  We both recognized some of the shortcomings of the AEC industry – the aversion to technology adoption, the skilled labor shortage and communication issues among plenty of others.  It was finally time to admit the problems, engage individuals to discuss them and publish proactive solutions for all to benefit from. 

Response was immediately enthusiastic.  But we knew the voices couldn’t be just ours.  It needed to be anyone and everyone in AEC who saw an issue and had a solution.  Each person we asked were happy to contribute posts and offer their view.  In this past year we’ve gained twenty-some contributors and have stayed true to our initial mission: to better the industry by sharing our knowledge, openly communicating & encouraging collaboration, all while being an unsponsored and unbiased platform.

We've received two best of construction blog nominations and in the process Mark Buckshon of ConstructionMarketingIdeas.com said 'This blog is one of the most solid interdisciplinary resources for architects, engineers, contractors and specifiers I’ve seen in the business.'  Not too bad for a side project that launched over Twitter direct messaging.

​The recent growth of programs advocating sustainable design is numerous:  LEED, Living Building Challenge, mindful MATERIALS, etc.  Through all of these, though, there seems to be a disconnect between specified products and installed items.  The owner is paying for something he didn’t receive, the architect is delivering a product they didn’t envision, the contractor is building a project that is not as described, and the manufacturer missed out on a sale of a product designed for the task.     

The Boss noticed a continuing pattern of building projects where there is a difference in collaboration and specification language of sustainable design between architects, engineers, and contractors and he wants me to look into it. Something’s not right in these specs and I can’t quite figure it out, but, I’m on it. My name is Specman; I carry a bunch of technical sheets.

8:15 AM.  The sun is bright, the coffee burnt, and my head is splitting.  I have been at this since 5 am this morning.  I reach into the desk drawer, shake the last two aspirin out of the bottle, and knock them back with the lousy coffee.   It’s going to be one of those days.   Thank God for the pharmaceutical guys; they’re my helpers. The 010000 General Conditions and 018113 Sustainable Design specifications are pretty clear.  Why didn’t this project get built with the appropriate materials as specified?  I don’t quite get it. 
                              
9:02 AM.  I phone the architectural specifier.  “Specifier”, she barks into the phone.  “What do you want?”  She’s a hard driven cookie; smart, but tough. Billable hours are important, there’s no time for small talk.   I called her Honey when I first met her; she made it quite clear she wasn’t an ex-wife or current girlfriend. Just because she was female didn’t mean she didn’t know her stuff and I would be well served to address her appropriately.  She was right then and right now.  She doesn’t know, however, that I call her Toots behind her back.    “Look, I need some answers and I know you can give them to me”.

“Yeah?”

“Yeah. What’s the deal with the intent of sustainable design that only encompasses half of the project?” I ask.

“What are you talking about, Specman?” she answers. “A sustainable project is sustainable throughout.  We just finished issuing the documents on that LEED Plutonium Level building. You know, the one intended to be loved and cherished by the community for time immortal. We covered all the bases:  Fasteners are made solely of recycled horseshoes; Ventilation is air movement generated by the wings of 100,000 Monarch butterflies and the Finishes are comprised of the most ecologically responsible building materials with a minimum 20% recycled rainbow content verified by an independent third party. What more is there?” I increasingly get the feeling I might be grabbing a tiger by the tail.    

“Well”, I answered, “someone else didn’t get the memo.  The engineer hired by you to design the parts of the building no one sees in this same project advocated Electrical Wiring as “throughout” and Piping as “leak free.”  Will that meet your sustainable design criteria?”

As a consulting specifier, my clients come to me for my expertise, and to bolster my knowledge I frequently find myself in conversations with product reps, talking about the nitty-gritty technical aspects of their products.  These conversations delve into a far deeper level of detail than I would previously get when I was a ‘normal’ design architect and project manager. Over the course of those conversations, I am occasionally surprised that things I thought I knew a lot about were based on misconceptions.  In fact, even things that I considered “common knowledge” have been shown to be wrong, or at least over-simplifications.  Armed with accurate information, I can pass correct technical advice on to my clients, hopefully dispelling those misconceptions one person at a time, one project at a time. 
 
Which leads me to the idea for this series of posts.  Misconceptions can be found across the spectrum, in every product category and in every MasterFormat number.  I thought it would be fun and enlightening to ask my go-to reps in a wide variety of product categories to tell me the biggest and most common misconceptions they hear as they work with designers and architects, and present their responses here.  In each post I’ll relate my discussion with reps in one category or one MasterFormat header.  So without any further ado, today’s Misconceptions.
 
The reps I chose to approach for this post, Andy Vegter from USG and Thad Goodman from National Gypsum, are both active and involved CSI members that I’ve come to know well over my career.  I consider them my trusted advisors when it comes to questions about their companies’ lines of gypsum-based products.  I’m not promoting their products over their competitors’ - it’s far more about the individual reps than the companies that they work for.
 
Without any further ado, today’s Misconceptions.
 
09 29 00 - Gypsum Board
 
I asked Andy and Thad this question:
 
“When you think about the questions and comments you hear from design professionals across all levels of experience, what misconceptions about gypsum products do you find that you most commonly have to dispel?”
 
First, this brief introduction - What is gypsum/gypsum board, anyway?”
​
Gypsum is a natural mineral, chemically made up of calcium and sulfur bound to oxygen and water.  It is found naturally in sedimentary rock formations, with some of the world’s largest natural reserves in North America. A synthetic version, which is a byproduct of coal burning electric power plants, is chemically identical to natural gypsum.  Some gypsum board manufacturing plants are fed with mostly synthetic gypsums and others are built over a mine where the gypsum is coming out of the ground.  Synthetic gypsum is considered a recycled material by sustainability rating systems, so projects seeking certification can specify that gypsum panels be made up of 90% recycled content.  It’s important to remember that not all products are available from plants that use synthetic gypsum. 
 
Gypsum board is manufactured when gypsum is mixed with water and additives to form a slurry which is then fed between continuous layers of paper or another type of facer.  Through a chemical process, the slurry hardens to its original rock state, and the facer becomes bonded to the gypsum core.  The boards are then cut to size and dried.
 
What follows are some of the most frequent misconceptions and misunderstandings that the reps related, followed by the correct information.
