Install drywall soffits faster and easier Now there is a better way to install drywall vertical drops. The newest Armstrong Installation Systems for drywall soffits are engineered to require less time and effort, while providing improved fit and alignment. QUIKSTIX™ Knockouts at 6" and 8" centers reduce cutting time. Alignment holes make screw installation simple and form perfect 30-, 45-, 60-, 75-, and 90-degree angles. Offset flattened bulb allows true angles without interference, and bending crimp prevents misalignment. New rout holes accommodate drywall tees, allowing larger section spans. You’ll save installation time with fewer ribs to create.

FRONT BY MARK FOWLER

Good, Fast and Cheap I recently was sent an e-mail by a contractor who said he lives by a simple rule: All customers want him to be good, fast and cheap, and that is just not realistic. All contractors bid work, which is an offer to do the work for a customer. The general contractor selects a subcontractor’s offer and prepares a contract, which has the additional terms the subcontractor must abide by beyond plans and specs. Many subcontractors are roped into signing a contract with terms and conditions that bear no resemblance to what he was envisioning during the bid and preparing the bid number. The subcontractor may agree to a timeline, sequence of scheduling, production rate and pay schedule, which in no fashion resembled what he was thinking. Many times the schedule is accelerated and there is little to no lead time, little tolerance and the pay schedule is set at a glacial pace. This where my friend’s rule comes into play. While the general contractor or owner wants all three, it is not possible to get all of them. My friend’s reply is, “Pick any two but you can’t have all three.”

DO A GOOD JOB The good is inherently most desirable. Everyone wants to do a good job and it’s not likely that they will give in on the good unless they use quality only as a sales slogan and are happy to write cheap bids, knowing quality is irrelevant. I believe that most subcontractors want to do good work. Fast is relative. Is “fast” a reasonable, well-scheduled pace or accelerated with people climbing over each other? Cheap is typically why the general contractor selected your offer—you were the low bidder.

| Walls & Ceilings | December 2011

Now we must discuss the “how good” and “how fast.” Consider that there are usually some severe penalties for not adhering to quality standards and schedule. When reviewing the contract, you should consider my friend’s advice that has become his company’s motto: 1. If you want good and fast, it won’t be cheap. 2. If you want good and cheap, it won’t be fast. 3. If you want fast and cheap, it won’t be good.

YOU CAN’T HAVE EVERYTHING The problem is that when you push for all three, you typically only get one and, thanks to reality television, the myth that all three are possible is streng thened. T hese rea l it y shows have a g roup of people build a home in only a few days. That is television and certainly not reality in the construction world. I have a good friend who worked on one of these shows where the home is gutted and rebuilt in only five days. He is a craftsman and noticed that crews were constantly directed to cover up work that was anything but good. It was also not cheap work. If not for volunteers and donated products, the cost of the project would be staggering. While the television show makes it seems like good, fast and cheap are possible, by pushing hard for all three, in “reality,” they got only one—fast.

GET REAL I believe most subcontractors know they can meet only two of the big three. It is that third piece that ruins all the best laid plans. If the client wants fast, he can get that by hiring more qualified people, accelerating the schedule, putting an extra supervisor on site and you have fast. But it does cost more money to do it good at that speed, so it won’t be cheap. If the client wants cheap, crews can be told to speed up production, relax tolerances and make the work of passable quality. This is where tract homes come from. Faster production and lower quality—it is not wrong or improper as long as it meets code and is within the realm of what will sell. I did it for years. We were low cost and fast; but the quality was not what we were able to deliver on custom homes or commercial work. This is also where tract style subcontractors get hit. They produce work t hey consider passable a nd t he owner or developer comes out with a straight edge or powerful light to shine on walls and then quote standards, some from their own manual that they made up. Some general contractors have an “accelerated schedule” and require workers to stand around and wait for an area to work on. This is not cheap for the subcontractor who pays by the hour and is also why piece rate workers are preferred. In either case, the result is workers climbing over each other to get their jobs done. It is called poor scheduling and bad supervision, and the end result is the “good” vanishes as they try to stay on budget. Remember these rules when you bid work and more importantly remind the client when they send you the contract, pick any two but only two. If you push for good, fast and cheap, you will probably only get one.

EU APPROVES LAFARGE SALE Belgian building materials group Etex won European Union approval on Friday to purchase most of French cement maker Lafarge’s plaster activities in Europe and South America. Lafarge is selling assets as part of a plan to cut its debt by 2 billion Euros ($2.83 billion), as reported by Robert-Jan Bartunek of Reuters.

The European Commission said the parties were not close competitors and the transaction would not significantly alter the market structure. While there was some overlap in the production of fire resistant boards, the commission said this would not have a major impact. “The boards made and sold by Etex and Lafarge are based on different materials and display different performance levels in terms of fireresistance time and their combined

market share does not give rise to any competition concerns,” the commission said in a statement. No reports at this time indicate how this will impact Lafarge’s U.S. gypsum and plaster division. W&C

Bob Baker, founder of Baker Drywall and Triangle Plastering, passed away October 14 after a yearlong battle Buchanan with cancer. Bob began working as a hod carrier (carried plaster mud before plaster pumps) for Storbeck & Gregory Plastering Co. in 1948. It was at Storbeck & Gregor y that Bob learned Baker how to do quantity takeoffs for lath and plastering. Later, he established several partnerships across Texas before settling down in Dallas to establish BakerTriangle. Bob focused most of his energy on the plastering division, while passing the drywall branch to his oldest son Steve, now Baker and Triangle’s CEO. Bob was able to grow his plastering company to one of the largest in Texas, completing such significant projects as: Myerson Symphony Hall, Bass Performance Hall and Lone Star Park. Baker had strong passion and knowledge of the lath and plastering trade and remained involved in the business until the age of 82, serving the industry for 60 years. He was especially proud of the work done on Lone Star Park because he was able to see many of his thoroughbred race horses perform there. Bob’s wife of 58 years, Frances, preceded him in death. He is survived by three sons, six grandchildren and a great-grandchild.

SCREWS FOR LIGHT GAUGE STEEL

KNOCKDOWN TEXTURE REPAIR TOOL

GRABBER CONSTRUCTION PRODUCTS

TEMPLATE LLC

The company’s Spectrum screw was specifically designed to produce exceptionally high pull-out values in light gauge steel without sacrificing fastener drilling speed in these new materials. Spectrum’s 7 gauge shank diameter, buttress threads and reduced drill point all combine to offer superior drilling performance. Additionally, the fastener is ideal for attaching high density sheathing products to the new materials being used in the market today. For all 16 through 20 gauge applications, the screw is specially designed to work with the next generation of steel framing.

The Drywall Repair Tool is a flexible plastic template with a random knockdown pattern that enables the user to replicate the knockdown texture on the rest of the wall after a drywall repair has been made. The process is clean and fast because there is no overspray and no need to tape off the area to protect the surrounding surfaces. The benefit to drywall professionals is that they can make multiple repairs more quickly after contractors have completed their work. The tool can be re-used on multiple projects, making it extremely cost-effective for those who perform frequent drywall repairs.

The highly engineered paper tape ensures excellent adhesion of joint compound, textures and paints for a strong, smooth finish for flawless corners. No screws, nails or other fasteners are required with the tape-on styles, making installation and precision corner alignment efficient while eliminating nail pops. The durable plastic also provides greater impact and abuse resistance, helping to reduce damage during transit and at the job site. The plastic bead is also 25 percent lighter than metal bead, making it easier to handle and more flexible to maneuver, especially in tight places like hallways and stairwells. Its light weight makes it easier to transport and helps save freight costs.

After multiple bid revisions and months of scope reviews, PCI was awarded the drywall/plastering bid package which included the following scopes of work: metal framing, insulation, drywall, finish, metal lath, traditional plaster, two-coat veneer plaster, EIFS, fire resistant joint systems, fire/ acoustical sealant, access doors, 3-D modeling of the Muriel and Helzberg ceilings and layout. The 1.93 million pounds of plaster was comprised of traditional plaster in the two halls and nearly 50,000 square feet of veneer plaster in the four-story glass lobby. A majority of the traditional plaster was on the 11,500 square foot Muriel Theater Ceiling and the

10,800 square foot Helzberg Ceiling. These ceilings have complex curves with a 2½-inch-thick cross section of plaster which equates to a 25 to 30 psf density rating. The remainder of the plaster was comprised of acoustical wall bumps which were designed to dissipate and divert sound waves to specific locations. With up to nine different psf density requirements throughout the halls, the plaster work had to be precise to say the least. T he complex radius and densit y of t he Mu r iel C ei l i ng a nd t he H el zb erg C ei l i ng were not only designed to be aesthetically pleasing but also were critical for peak acoustical performance. To achieve design criteria, both ceilings were 3 -D modeled and the stud locations were pre-determined to avoid clashes with critical light placement and other penetrations. T h roug h t he modeli ng process, PCI was able to engineer and have the 16 gauge, 4-inch ceiling members pre-bent to the designed radii. This allowed PCI to frame these two ceilings with a three-man crew over five months with very minimal modifications due to clashes with other trades. In addition, the Total Station (described below) was used to lay out support straps and radius studs in the Muriel and Helzberg Ceiling. The construction of the wall systems were also a challenging pro-

cess throughout the duration of this project. The layout of the walls was based on three different grid systems, one for each hall and one for the rest of the project. To add to the complexity, the majority of the gridlines were splayed, non-parallel and radiused. To help with the layout process, PCI elected to use a robotic Total Station by first plotting points using Auto Cad and then implementing them in the field using the Total Station equipment. Upon completion of layout, PCI had to decipher and process the staggering amount of variables associated with the wall types on the project. Having 68 wall types with each having three head of wall deflection criteria (0, 1 inch, 2 inch), PCI quickly had hundreds of variations in wall types. Combined with the addition of fire track, slotted track, double studded walls and up to six layers of drywall, one can only imagine the skill required to process and accurately execute the construction of the walls.

Specialty items included multiple custom made-precast caps and sills, and limestone plaster coating over drywall to simulate stone in the interior public spaces. Fort Collins Precast provided the precast materials. This was a challenging project due to the complexity of details, the multiple scopes performed, and the “fast-track” schedule. The large scale of the project, combined with the scaffold erection and weather protection during the winter months, and over 68,000 man hours in the field, made this dynamic project a consistent management challenge. This project demanded the cooperation of multiple scopes and tradesmen, all working together to produce a quality and functional building that has significantly changed the landscape of the area and provides St. Anthony’s Hospital with a stateof-the-art facility to help them continue to provide the exemplary medical treatment they are known for and

He proposed using the handapplied and formed product because it gives his workers the ability to create the same look as the Barbados stone at a cost and time savings. Another benefit of using the hawkand-trowel product is that Ford’s workers are able to make corrections to imperfections in the substrate that would have been much harder with the less-forgiving stone. The ArcusStone product was also good for making the molds and architectural profiles the job called for by hand. The bowed ceilings and arches were much easier to do compared to stone, Ford says. There were other benefits to working with an American-made product, he says. There was no dealing with import/export officials, a far lighter product to handle and transport, and the benefit of getting a 12-year warranty from the manufacturer that might not have been available with the stone. In all, Ford estimates his company saved several months and between $600,000 and $700,000 for the client. At the same time, the more than 40,000-square-foot project gave him and his workers a great deal of practice in turning out artistic finishes in the field. Allied Building Products supplied materials for the project.

Materials: Quad-Lock, Fry Reglet, Pella Windows, Rubio, Monocoat, Gris Belge, Buechel Stone Planned as a 100 year-plus home, this Quad-Lock ICF project was designed with many generations in mind and has been designated in the estate plan. The project’s 4,000 square foot size is large enough for extended family accommodations with small bedrooms on the basement floor, ADA accessibility for two regular inhabitants on the first floor with their place of business located on the second floor. Experienced with LEED commercial projects, the architect and builder designed the live/work home space with LEED guidelines in mind. Thus interior air quality, energy and water conservation, waste reduction and lower operating costs were primary goals of the project. The Quad-Lock ICF system was chosen to help achieve those goals. Built into a rugged and hilly 35-acre site, the project juts into the horizon with large cantilevering rooflines whose forms appear to hover over the extensive glazing that allows expansive 20-mile panoramic views to the east, south and west over the historic Wisconsin River Valley and six neighboring towns. In addition to creating the sensation of being in a cave overlooking the vista; the overhanging, dark stained cedar and pine roof/ceiling forms temper the summer heat while holding back winter’s chill.

This juxtaposition sets the stage for the underlying story of the home that is seen in the interplay between the form and the material palate. Themes of dark and light, heavy and delicate, solid and void, expansion and contraction, rustic and refinement can be seen throughout the home. This project is exemplary in its well thought-out planning and execution of details. High performance building systems, such as in-floor radiant heat and high velocity air handling coupled to a vertical geothermal field are deftly integrated and are barely noticed while allowing the home to function at energy costs lower than a project half the size.

The Cosmopolitan Resort and Casino project was originally budgeted at $2 billion (KHS&S scope approximately $75.3 million) when KHS&S began work on the project in October 2007. The scope originally included all the metal framing and drywall for the interior of the podium and recreation deck, exterior EIFS at the podium and recreation deck and thematic items throughout the podium. KHS&S was contracted to provide design-assist services for all new venues. The opportunity to be a part of the design-assist process made it possible to work side-byside with the project designers, architects, Perini’s project and field management as well as the new owners. This allowed KHS&S to streamline pricing and design and offered an opportunity to improve the contractor’s relationship with all parties. The redesign of the Cosmopolitan also created an opportunity for KHS&S to nearly double its contract value to approximately $146 million by completing the metal framing and drywall for the 1.85 million square feet of podium space. The owner never stopped changing the design, but they also did not spare any expense to create the final product they envisioned. The project was successful; it was delivered on time and within budget. Constructing the interiors and exteriors of the Cosmopolitan indeed had its fair share of challenges. Most of the exterior walls were designed with faceted and undulating geometry and not the typical vertical wall as seen on most buildings. Combine this with wall spans of 100feet plus and a still-under development building design all made for rather unique obstacles to overcome. For the north and south exterior walls of the podium, as well as the night club, KSH&S used a light gauge metal truss system manufactured by M-Truss normally used to frame roofs. The design is similar in nature but in this application the roof would be tilted vertically and attached with metal clips back to the building structure. Throughout the course of construction, the interior walls, ceilings and soffits were under constant design and redesign. In the end, what was initially scheduled for six months of preconstruction design turned into almost three years. Due to delays caused by the redesign of the schematic layout of the podium levels, the construction means and methods had to be altered. The “attic” space, what would become the finished ceiling, was being filled in with MEP

lines and equipment, and the building structure above was many times no longer accessible. Most of the Level 1 casino ceiling required the installation of a 4-foot-by-4-foot tube steel grid that was suspended from the concrete deck above. This gave a flat level surface for which to suspend the light gauge metal soffits from. So somewhere between schedule, cost, design, ownership change and designer change, KHS&S managed to draw, review, build, redraw, tear down and rebuild the interior walls, ceilings and soffits twice.

WHAT HAPPENED?

drywall vs.

plaster A

not so long time ago and in our own galaxy, interior plaster was king and drywall was considered a second rate product, but that changed in a big way fast. In the 1950s, you could hear terms like “button” board and “hardwall” on virtually every project. Drywall was not taken seriously. But, after the span of a single decade, plasterers stopped laughing when drywall became the dominant finish. Did interior plasterers just give up without a fight? No, they fought and spent money on marketing plans to regain market share. If you think that failure was inevitable, consider that today interior plaster is still more popular in Europe than drywall.

ILL-PLANNED MARKETING The post-World War II era created a housing boom like this country had never seen before. Builders wanted

26

| Walls & Ceilings | December 2011

When drywall appeared on the market, plasterers mounted a campaign to discredit its use. How did that fail? By Mark Fowler less costly, faster construction, the tract home was the revolution and drywall was a natural fit. Plastering contractors had to do something to prevent erosion of their market share. In California, a marketing firm conducted research to devise a s t rate g y to pre s er ve m a rke t share against the drywall invasion. Through interviews and surveys, they learned homeowners did not seem to appreciate the benefit of lath and plaster. A marketing plan was established based on some very basic assumptions about the difference between plaster and drywall. 1) Plaster was harder and more durable than drywall.

2) Plaster had better sound attenuation than drywall. The marketing strategy became obvious: a two point attack on the builder and the home buyer was launched with the message that plaster walls are better walls. It was believed that if the home buyer knew the difference between drywall and plaster, they would demand plaster every time. The easy test method that anyone could try was to “knock on the wall.” T he hom e bu i ld er promot e d quality, as per his advertisements, and the plasterers would help with promotional items like signs and

as concerned about drywall. They came up with a solution, skim coat or veneer plaster. It could be put up faster than drywall and would save time and money com-

brochures to display at the model homes to demonstrate that they used lath and plaster, not drywall. T he campaign went so far as to include radio and newspaper advertisements. The catch phrase “ K n o c k o n t he Wa l l” i s s t i l l remembered by many in the trades and it was pushed hard for a few years during sporting events like professional baseball.

THE FACTS Home buyers walking through a tract home are not going to demand plaster or pay extra for it. Did anyone really believe that potential buyers would walk out on a home sale because it did not have lath and plaster or buy a home because it did? While builders promote quality, at the end of the day, they demand cheaper and faster turnover. Drywall was cheaper and faster to install. The home builders also learned quickly that buyers only paid more for upgraded appliances and fixtures, not plaster walls. Plasterers had exteriors (stucco) to work on and the housing market was booming, so the loss of interior plaster work was not really critical—they still had a lot of work. Builders claimed plaster was too expensive and took too much time. Plastering is still bigger in Europe than America? How could that be? One main reason was masonry walls were, and still are, a main building material there and plastering over masonry involves no great loss of time. In addition, the extra cost of furring out masonry, hanging drywall and taping is not cheaper than just plastering a masonry

wall. The reason why America lost interior plastering runs even deeper than this. The American plasterer could have saved interior plastering back in the ’60s, but he refused to adapt or change.

drywall vs.

plaster pared to traditional lath and plaster. It must have seemed to manufacturers that interior plaster was about to be saved. Alas no. Was it a lack of skilled workers with trowels? No, we had thousands of trained and skilled plasterers. So why did it fail to capture the market in America? I found the primary cause for the new skim coat plaster failure from the 1960s when I was remodeling my home a few years back. I used a veneer skim coat plaster on my home and my father offered

to come over and help. He and my uncle, old time plasterers, were in the heart of the transition from genuine lath and plaster to drywall. They often talked about “cheap dry wall” and how it ruined the industry. As we started to spread the veneer plaster, my father asked, “What is this stuff?” He had a sudden recollection and exclaimed “this is the stuff they created to compete with drywall back in the ’60s,” in an irritated voice. He went on to explain that this was an

imitation for real lath and plaster and, in his day, they refused to use it. He also noted how the material did not work like the real finish or putty coats of his day. It was not as friendly to work with. What would have happened if they had embraced the skim coat plaster? Would history be different? I love plastering and have nothing but the utmost respect for the trade and the great plasterers out there, but cutting off our noses to spite our faces is just not smart business.

The fallout from this transitional era may have had longer lasting repercussions that many of us are not fully aware of. Is it possible a cultural change occurred back then and the effects are still being felt today? The wall and ceiling industry prior to the 1960s was more contractor-driven. Standards, codes and even products were all centered around the contractor’s needs. Consider that the manufacturers developed a new plaster to “save” interior plastering and it was rejected. The innovative skim coat plaster system was developed to be competitive in cost, faster in application and to provide an abuse resistant wall. The system was dubbed as a sell-out or second cousin to real or genuine lath and plaster. The plastering contractors made the unfortunate stance of “all or nothing” and that’s what sunk lath and plaster. W&C If you read this article, please circle number 141.

With seven units now completed and sold, and seven more under construction, Powell believes his determination to feature only high-performance, low-maintenance products in the homes has led to the project’s success. “We will have 58 homes and a clubhouse in this Jack Nicholas Signature Golf Course community on the Paw Paw River when it’s completed,” says Powell, owner of Powell Construction Services, LLC out of St. Joseph, Mich. “Every one of those homes will feature high-performance Simonton ProFinish Brickmould 600 windows and patio doors. Many of the entry doors are Energy Star qualified fiberglass door systems from Therma-Tru. And, the home foundations feature energyefficient Superior Walls pre-cast concrete wall panels reinforced with steel and insulated with Dow Styrofoam to create a permanent barrier against sidewall water penetration. “I’ve selected the products I would want in my own personal home to assure that the residents here have the ultimate living experience,” Powell says.

GREEN BUILDING STANDARDS Every home in the Cottages at Harbor Shores Hideaway community is being constructed to the NAHB Green Building Standard. The homes are third-party certified Green Built Homes with a Gold Rating, which exceeds the Energy Star Five-Star

Using only materials he’d use on his own home, Greg Powell is constructing a golf course community on Lake Michigan that will be Gold-rated green and easy to maintain By Kathy Ziprik Plus certification. Powell Construction homes are certified through Green Built Michigan and follow the national Model Green Home Building Guidelines. The NAHB Green Approved Superior Walls foundations used in the homes are the only foundations approved to contribute points toward certification of a structure under the National Green Building Standard. “Creating an energy-efficient, high-performance home is all about the products you select for the home and the construction practices you employ,” says Powell. “These homes are constructed to be just as comfortable during our rough Michigan winters as they are during our perfect summer weather. “As much as performance is a key goal of ours, aesthetics is also critical when designing and constructing these cottage-style homes. Using the Simonton products with the integral brick mould created as part of each window frame gives us a consistent, stylized look throughout the entire community. Then, complementing those windows with shutters and entry doors that are architecturally appealing with unique accent colors helps us make these cottages stand-out. The glass and color options we selected in the Therma-Tru doors also add to the curb appeal of the home while providing interior accent designs.”

LIVE LIKE YOU WANT The Hideaway Cottages neighborhood developed by Harbor Shores and being exclusively built by Powell Construction is located along the north shore of the Paw Paw River and close to Lake Michigan. Spanning 530 acres and located in Benton Harbor, St. Joseph and Benton Township, the Harbor Shores development is the first beach and signature golf resort community in southwest Michigan. Cottages in the development (which include the lots) range in price from $350,000 to $600,000. “Maintenance-free living is a key feature of this community,” says Powell. “The homeowner association fees cover community maintenance along with landscaping and snow removal. There’s so much to do here during every season that homeowners don’t want to spend time on the mundane chore of maintaining their home exteriors. On any given day, residents can play golf, enjoy the neighborhood clubhouse, swimming pool, fire pit, or canoe and kayak on the river. We’ve created a ‘community for life’ that truly enhances the lives of its residents.” W&C Public relations expert Kathy Ziprik has worked exclusively in the building products industry for nearly 20 years offering support to a variety of manufacturers.

FINISH LINE BY ROBERT THOMAS

Know Your EIFS When EIFS was first introduced to the North American market, there were a lot of questions about its strength. This particularly revolved around the use of EIFS on lightweight stud walls with gypsum board sheathing substrates. This concern proved to be unfounded and since then EIFS has been used on some very large buildings, including in areas where strength is an issue (windy areas like the Gulf of Mexico).

NONSTRUCTURAL CLADDING VS. SUPPORTING WALL EIFS is a nonstructural material. It does not support the wall. This makes it more like a curtain than strong materials like concrete block that can be used to support the building. The wall that supports the EIFS may be structural, including having load bearing structural studs.

BUILDING SITE LOCATION The physical location of an EIFS application has a bearing on the amount of strength it should have. Hurricane areas, for instance, require stronger attachment than areas that are not windy. The building codes have maps that indicate the minimum wind forces to which walls must be designed. Wind forces act in two directions: they push the cladding into the wall (positive force) and they also try to pull the EIFS off the wall (negative or suction force). The latter mode is more of a concern than the former, as the cladding can become loose. Wind forces are higher at the corners of buildings than in the center of large wall areas. The suction forces are highest on the backside (away from the wind direction) than on the front side. Wind forces increase with the height of the building and the area that gets the most wind action is often the downwind parapet area at the corners. This is why you often see flashings torn off the edge of roofs during storms.

32

FOAM THICKNESS Thicker applications of EIFS foam insulation make the EIFS stiffer and stronger. This is due to the reinforced composition of the EIFS coatings and substrate. However, this strength increase due to the use of thicker foam is not taken into account when designing EIFS cladding to resist wind.

COATINGS VS. FOAM VS. ATTACHMENT The foam insulation is the weakest material in EIFS. Attachment by using adhesives, which spreads out the wind forces over the entire foam layer, are much stronger than a small number of mechanical fasteners (washers and screws). Adhesive patterns, such as closely spaced notched trowel stripes, are stronger than the traditional ribbon and dab pattern.

ADJACENT BUILDINGS Buildings adjacent to each other affect the movements of wind over each other. This is due to the channeling effect of the wind moving between buildings, such as on streets and alleys. On tall buildings in built-up areas, wind tunnel tests and computer models are used to predict what the wind forces will actually be. This force is factored into the plans for the building, no matter what the minimum tolerances required by the building codes are.

SOLID SUBSTRATES VS. SHEATHING Heavy, stiff, solid walls—such as concrete and block—make the best substrate for EIFS. They do not move much and provide a rigid surface onto which to attach the EIFS using adhesives. The use of lightweight stud/ sheathing substrates for EIFS is not as common outside North America.

MOISTURE ON SHEATHING The presence of moisture can affect the performance of sheathing. It can weaken the ability of the sheathing to resist wind pull-off forces. This damage can occur before the EIFS is installed and can be due to water leaks in the sheathing. This is especially true of older paper-faced gypsum sheathing and moisture sensitive wood-based sheathings, such as oriented strand board. Thus, it is important to protect the sheathing during the initial construction process and to do regular maintenance so that water does not get into the wall.

FRAMING AND DEFLECTION The stiffness of framing is important. This stiffness is a measure of a property known as deflection. Deflection is the in/out movement in the plane of the wall due to wind. Deflection is usually expressed as a percentage of the distance between the attachment points for the framing—known as the span. EIFS is a fairly flexible material and for most EIFS the maximum allowable deflection is 1/240th of the span. The stiffness of the framing is related to the depth of the framing, its shape and the thickness of the metal. A 6-inch stud is much more than 50 percent stiffer than a 4-inch stud.

FASTENING PATTERNS If mechanical fasteners are used to attach the foam to a structural substrate like plywood, you can locate the fasteners where you want and use as many as you need. With nonstructural substrates like gypsum board, the fasteners need to go into the studs. This limits their number and spacing. Since plywood and other woodbased sheathings are combustible, they can’t be used on large commercial buildings where building codes call for noncombustible materials. To remedy this, adhesives are used on commercial buildings.

IMPACT DAMAGE When initially introduced to the North American market, there was concern about the resistance of the thin EIFS coatings to being damaged

from being struck by hard objects. At that time, only lightweight reinforcing mesh was available. This problem had been addressed in Europe, where EIFS was initially developed, by the use of heavy mesh. The heavy mesh was imported to North America and solved the problem for most buildings. However, the heavy mesh did not completely solve the problem—especially on lightweight walls using studs and sheathing where breaches in the wall could cause problems. In cases of buildings such as banks, the penetration resistance comes from the supporting wall, which is usually masonry or concrete. Thicker EIFS basecoats improve the impact damage resistance as does the use of the more flexible, cementless basecoat adhesives. Higher density foam also helps but can contribute to the tendency of the EIFS lamina to crack. This is why low-density, springy EPS foam is used.

is where stud framing abuts a more rigid substrate like concrete. The difference in springiness of where the two substrates meet can cause the EIFS to crack. This is why EIFS producers require an expansion joint where the types of substrates change.

PUBLISHED STRENGTH DATA EIFS producers publish strength data on their products with tolerances given various attachment methods, substrates and stud spacing. This information is in their catalogs as well in product approval documents issued by code agencies such as the International Code Council. W&C Robert Thomas is a nationally recognized EIFS consultant, based in Jacksonville, Fla. He was the manager of technical services for a major EIFS producer, is the author of

RACKING This is the movement of a wall going out of square along its own length. It is caused by forces pushing against the wall along its face, such as high wind or earthquakes. Glass reinforcing adds substantial resistance to racking but this is not taken into account when using EIFS. Instead, the sheathing, straps or other forms of bracing on the studs are used.

SAFE SIDE BY MICHAEL RICH

First Aid Regardless of the amount of safety training and precautions you take as a company, at some point in time an accident will happen. When that accident does occur, do your employees know the proper way to react? This article will focus on the treatment and identification of cuts and lacerations that are constantly ranked as the most common workplace injuries. Typical causes of these lacerations include improper training, lack of established safety procedures, employees in a hurry, taking short cuts or not following safety procedures, failure to wear cut-resistant gloves or wearing improper gloves for a job, missing or improperly adjusted guarding, poor housekeeping, poor lighting and more.

IDENTIFYING THE TYPE OF WOUND A bleeding wound is typically one of the four varieties: 1. Abrasion: An abrasion is a wound that is caused by friction. Signs of a friction wound are typically missing skin and minimal bleeding. These wounds are typically of a minor nature. 2. Cut: A cut refers to a wound in which there is separation of the tissue. Unlike an abrasion, none of the skin is missing. A cut is a wound caused by a sharp object. T hese wounds can vary from minor to serious. 3. Laceration: A laceration is a torn or jagged wound. The typical cause of a laceration includes a blunt trauma (such as a blow, fall or collision). Cuts and lacerations can be grouped in the same category and the terms are often interchanged. 4. Avulsion: An avulsion is wound where tissue is not just separated but torn away from the body. These wounds are typically serious in nature.

34

| Walls & Ceilings | December 2011

DETERMING TYPE OF BLEEDING Capillary bleeding: This type of bleeding is caused typically by abrasion wounds. The wound opens tiny capillaries just below the skin’s surface. Capillary bleeding usually slows or stops before any serious blood loss can occur. Ve n o u s bl e e d i ng : T h is for m of bleeding is caused from deeper wounds to the tissue puncture veins. It is characterized by blood that is dark red in color and slowly exits the body. This type of bleeding is typically not life-threatening. Arterial bleeding: This type of bleeding is caused by the laceration of an artery. It is characterized by spurting blood that is bright red in color. Arterial bleeding is the most difficult type of blood loss to control. Even a small, but deep, arterial puncture wound can cause the loss of life. Seek medical help immediately if this type of bleeding is suspected.

TREATMENT When an employee suffers a cut, it is important to treat the wound immediately. The first part of treatment is to stop the bleeding. To stop bleeding, put pressure directly on the wound with sterile gauze or other bandages. This, coupled with elevating the wound above heart level, should stop the bleeding within 15 minutes. If the bleeding won’t stop after 15 minutes, try to use the pressure point nearest the wound and call for emergency medical help immediately. (Common pressure points: Arm between shoulder and elbow—the brachial artery; groin area along bikini line—femoral artery; behind the knee—popliteal artery.)

CLEAN THE WOUND Once bleeding has stopped, clean the wound by washing the adjacent skin with soap and water, and removing crusted blood with diluted hydrogen peroxide. Next, irrigate the wound by squirting a saline solution into the wound. This is a highly effective way to reduce the potential for bacterial infection. If bleeding starts during the treatment, reapply pressure.

REPAIR/BANDAGING A fter cleaning the wound, it is important to properly bandage it to prevent infection. To do this, apply an antibiotic cream to the inside of the material being used as the dressing. Next, cover the wound with the dressing. The dressing should extend beyond the wound by about 1/2 inch so that it covers the wound completely and allows room to affix the dressing to uninjured skin. Once the dressing is on the wound, cut four strips of athletic tape and use them to attach the dressing to the skin. If there is a risk that the wound will be exposed to water, cover the bandage with waterproof material, such as waterproof tape or plastic.

A VISIT TO THE ER? Use these questions to evaluate if you need to send an injured employee to the emergency room: • Can you stop the bleeding? • Are the wound edges separated? • Can you adequately clean the wound? • Is it possible that serious underlying damage was done (such as a cut nerve or tendon)? • Has the employee had a tetanus shot in the past 10 years?

TROWEL talk BY WILLIAM E. ROGERS, ACP

One Good Turn He was born in a dusty little town in nowhere New Mexico, coming of age during the height of the Great Depression. To earn money as a teenager he found a solution to a local problem. Due to the demand of the war effort, local ranchers couldn’t get metal to replace their rusting water and feed troughs. He discovered that by taking a hatchet and poking a bunch of holes in the rusting containers to create a “key,” he could layer cement mortar inside and out and create a usable and durable container, extending the life for years. He earned enough to buy an old truck and a small travel trailer, packed up his wife and baby and headed to California. When they finally arrived in the Golden State, they settled in Riverside, a rural community where land was cheap and orange groves were plentiful. To find work to feed his family, he walked onto a job site, a new church being built. He watched as the plaster crew was running molds and stuccoing the exterior. He found the foreman and convinced him that he was a “plasterer” although his only experience was lining water troughs. He was told to go up on the scaffold to help run a mold around the large stained glass window. It didn’t take long for the man he met up on the wall to tell him didn’t know what he was doing. The two men had a brief and frank conversation. He was allowed to remain on the job and soon joined the union. The two men worked side by side for several years and became fast friends. When he decided to get his contractor’s license and to go into business for himself, his friend quit and came with him to become his foreman. At the height of his company’s success, he employed more than 60 union plasterers and hod-carriers. In the late-’50s he was awarded one of California’s first shopping malls, the Riverside Plaza. As the 1960s passed and he grew older, he began to reduce the number of employees and returned to working

with the tools. His work drifted away from new construction and towards remodeling and historic restoration.

GOOD AND PRODUCTIVE RULES OF LIFE In 1969, his adult son died unexpectedly and a year later he took a young 14-year-old boy into his home that had been abandoned by his family and was found living in a countysupported group home. There were only two rules to living with him and his family: 1) Attend school, and; 2) When not in school, go to work with him on the job site.

When the boy graduated high school, he took him down to the union hall and said, “Sign him up, he’ll make a good apprentice.” That was 36 years ago. A year later that young boy won the California State Plasterers Contest. He finished his apprenticeship and went on to work on some of the most elaborate plastering projects in Southern California before being elected as a business agent for the union. Today that same boy is the Executive Director of the National Plastering Industry’s Joint Apprenticeship Trust Fund. Thanks, Dad Lynn T. Rogers (1921 – 2011) William E.

GREEN BY CHRIS DIXON

The

Scientific Method It’s impossible to have a green building without paying close attention to building science. A building constructed without building science will be green in name only and begin showing its un-greenness eventually— by using more energy than predicted, exhibiting moisture problems and suffering premature failures of systems, components and materials. This point is driven home in every building science paper I have read and in every building science seminar I have attended. I was fortunate to have attended a recent building science fundamentals seminar put on by the gods of building science, Drs. Joe Lstiburek (pronounced STEE-brook) and John Straube. The seminar was done in a tag team format; Lstiburek and Straube took turns, going back and forth 45 minutes each for eight hours a day over two days. It was intense and informative. The list of subjects on the agenda included rain control, air control, heat, air and moisture movement, insulation and thermal bridges. Last on the list was green building/sustainability. Near the end of the second day a participant asked: “When were we going to talk about green buildings?” to which Dr. Straube replied: “Isn’t that what we’ve been doing?”

BUILDING SCIENCE IS BORN A long time ago, buildings were made of simple materials like timber and stone. They were durable and relatively maintenance free but not all that comfortable. As time went on, new building materials like steel, concrete and fl oat glazing became available, which allowed designers to create lighter, less massive buildings with lots of windows. Discovery of cheap, abundant fuel sources allowed buildings to be built in less hospitable climates. As the price of energy went up, aware-

| Walls & Ceilings | December 2011

ness of the importance of air control and insulation followed. The real problems began when these new buildings got tighter and better insulated without a thorough understanding among designers and builders of the relationship between light building enclosure assemblies and heat, air and moisture movement. Building science as we know it today began as a fi x for one problem which caused others to erupt. H ig her energ y cost s led to a n increase in insulation which led to rotting, corroding moldy walls (cold condensing surfaces in cavities were created) which led to the requirement for a vapor retarder which led to more rotting, corroding, moldy walls (moisture in the wall cavity no longer able to dry out) which led to the discovery that an air barrier is necessary (holes in the assembly allow a much greater transfer of moisture than a vapor retarder) which led to the discovery that ventilation is necessary (tight buildings with poor ventilation have high relative humidity, more moisture problems and poor indoor air quality) which led to more HVAC equipment to move more air which led to pressures created within the building sucking and blowing within and across the enclosure which led, you guessed it, to yet more moisture problems. Most of us are still trying to figure this stuff out, which means that many buildings are still being designed without enough attention to building science fundamentals resulting in buildings that do not perform as well as they could.

MOVING FROM REACTIVE TO PROACTIVE Building codes are an excellent example of a reactive response to problems that arise in buildings. Historically, building codes change after problems in buildings occur through requirements meant to prevent known problems from recurring—and for good reason! It would be impossible to anticipate all things that could go wrong with a building before they actually happen. Reactive responses such as building codes usually result in prescriptive requirements. An example of this is the prescriptive requirement that a vapor retarder with a perm rating of less than 1.0 installed on the warm side of the exterior enclosure, no exceptions. Those that are up to snuff in their building science knowledge will recognize that this requirement could, in fact, create more moisture problems in certain situations such as reverse vapor drive in an air conditioned building with a reservoir cladding like brick veneer. A vapor retarder on the interior can cause condensation to occur with the wall cavity when the sun heats up the wet brick and drives moisture inward. A proactive approach moves away from a prescriptive requirement to a performance-based requirement. A recent performance-based change to the International Building Code includes three classifications of vapor retarders, and provides options for using each type depending on the climate zone, the cladding and the insulation used—it only took 40 years! In addition to causing moisture problems, buildings with poor air tightness can require significantly more energy to heat and cool. A recent NIST study designed to evaluate the energy impact of improved air barriers found that buildings in hot climates use up to 16 percent less energy with a good air barrier and buildings in cold climates up to 37 percent less. The reactive energy code approach to solve this problem merely requires that the building have tight-fitting dampers at flues and vents, that they use

materials that pass an air barrier test and that they be adequately sealed. These measures do not guarantee an adequate reduction of air leakage. The current City of Seattle Energy Code offers an example of a proactive, performance-based requirement with regard to air tightness. The new code requires that construction documents show a continuous air barrier at the exterior enclosure and that the building be tested for air leakage upon completion.

THE PERFECT ENCLOSURE Building science is confusing. It is a subject that is not addressed very well by university architecture programs in North America and not well understood among practitioners. To design a building enclosure properly, for any given building, in any given climate, a building designer must be able to answer the following questions: • Is a vapor retarder required? If so, at what perm rating? • What is the proper location of the vapor retarder if required? • What is an air barrier? What is the proper location of the air barrier? • What is required to make the air barrier continuous? • What is the required R value of the enclosure?

• How is the R value of the enclosure calculated? • What measures are employed to prevent thermal bridging? • What is the condensation potential with the enclosure assembly? In the summer? In the winter? • Is reverse vapor drive a potential problem? • Is the drying potential of the enclosure compromised in any way? Answering these questions for every enclosure assembly for every building in every climate would probably give most building designers a headache. L stibu rek a nd Straube have made life simpler for them, however, by developing what they call the Perfect Wall (turned up to make the perfect roof and down to make the perfect floor to complete the enclosure). The Perfect Wall keeps water from getting into the building from the outside (rain and reverse vapor drive), from the inside (vapor diffusion and air transport) and lets the water that starts out in the assembly (water saturated wood for example) escape. It locates the vapor diffusion retarder correctly for every climate while simultaneously acting as an air barrier. It addresses thermal bridging which results in a high R value. It addresses each ques-

tion above in an elegant, cost effective and efficient way and the buildings constructed under the program will last for decades.

CONCLUSION A green building must begin with an enclosure that satisfies building science fundamentals. A welldesigned enclosure ensures that heat, moisture and air are properly and effectively managed resulting in a building that is comfortable and safe for occupants, thermally efficient, dry and very durable. Building codes are getting there, but as a reactionary approach to problems, they can’t get you all the way there.

CONTRACTOR PROFILE S P O N S O R E D B Y A L L I E D B U I L D I N G P R O D U C T S C O R P O R AT I O N

Growing by building Allied Building Products’ Contractor of the Month: J&J Acoustics Inc.

L

ocated in Santa Clara, Calif., J&J Acoustics Inc. is approaching its 35th anniversary. Founded in 1977, this wall and ceiling contractor is a very competitive-and more importantly-aggressive contractor. The company, with one location, does contract work on drywall, EIFS, exterior wall panels, light gauge steel framing, metal lath/furring, plastering, acoustical ceilings and more. Most recently, the company has utilized BIM modeling software, a good niche service to offer. J&J Acoustics is a union shop affiliated with the Northern California Carpenter’s and the Bay Area Painter’s, Taper’s and Decorator’s unions. With one location serving the Bay Area and beyond, the company is still going strong. Joe Jean, now the president of J&J Acoustics, has been involved with the trades since his teens. “I have been involved in the drywall business since I was 13 years old,” Jean says. “I have a degree in Construction Management from Chico State and have been involved in the family business since 1996.” Currently, J&J Acoustics has four senior estimators/project managers, five project engineers, three superin-

tendents and more than 225 union field employees with an office staff of seven.

YES, WE DO THAT

BALANCE

The company specializes in every type of project from Office T.I.’s, healthcare, multi-unit residential, educational, hospitality, airports and more. “There is nothing we cannot do that involves metal stud framing, drywall or plaster,” Jean says. “Customer service is our number one priority.” The company does do government work. One project that the company cites being very proud of is the New San Jose Civic Center, completed in 20 05 for Devcon / Turner Joint Venture. “I have always been fascinated at the team work involved in the construction of a project! I also get a great sense of satisfaction knowing that you had a part in the successful completion of a project,” says Jean. And how does the company deal with such challenging jobs? By having a great team of employees in place, Jean says. “The employees at J&J Acoustics find a way to get the job done no matter what.”

AMS, an affiliate of Allied Building Products, is J&J Acoustics preferred supplier. AMS supplies the contractor’s metal studs, drywall, lath, plaster and acoustical T-bar material. And how does this successful wall and ceiling contractor kick back? “I enjoy spending time with my family chasing my two kids around from one sporting event to the next,” Jean say. “I think it is important to maintain a healthy lifestyle so I also enjoy staying active doing things like golfing, mountain biking, handball, skiing and hiking.” In closing, Jean says he is proud to be part of such a great team as J&J Acoustics. The majority of its employees have been with the company for more than 15 years. “Any success we have achieved as a company over the years is attributed to the dedication, loyalty and professionalism of everyone that works at J&J Acoustics,” Jean says.

• Training all employees in good safety and health practices. • Establishing communications regarding workplace safety and health. • Developing and enforcing safety and health rules and requiring employees to follow these rules as a condition of employment. • Recognizing employees for safe practices or performance and counseling employees for failure to follow safe and healthful practices. J&J Acoustics recognizes that safety is a shared responsibility. J& These responsibilities can be met only by working continuously to Th ppromote safe work practices among all employees and to maintain property and equipment to create a safe working environta ment for all employees. m
