1 CROSS LAMINATED TECHNOLOGIES - USA CLT 3xW The What, Why and When success story of CLT Technology Presented by MDS10 pllc, Architects and CLT USA, LLC C. Crawford Murphy, Architect & President Michael J. DeVere, Architect & CEO

2 Company History Organized in Brought CLT to the attention of universities, builders, and architectural firms in North America. Secured grant funding for academic research in the use of Southern Yellow Pine for CLT manufacturing. White Paper from NC Department of Insurance, acknowledging CLT as an approved building material. Designed, engineered, procured, and erected first commercial CLT structure in USA. Helped draft the APA / ANSI Standards for manufacturing of CLT in North America. Initiated a process with Patrick County, Virginia, for financing of our initial start-up and future plants. Identified initial plant site with municipal support, potential key corporate personnel and strategic partners. Gained endorsement of US Army Corps of Engineers and Department of the Army.

3 What is Cross Laminated Timber? Cross-Laminated Timber (CLT) panel consists of a series of milled timber planks that are stacked, glued and laminated in perpendicular layers. The gluing takes place using ecologically friendly adhesives that are both solvent-free and formaldehyde-free. The glue is applied automatically over the whole surface and then subjected to approximately 120 pounds per square inch of pressure that provides a very high-quality level of adhesion. Material used in the fabrication of CLT Panels are factory dried to achieve a very low moisture content (12%). Resulting panels are strong and have favorable acoustic, thermal, fire resistant and seismic resistant characteristics. Environmentally preferable substitute for concrete, steel, and oriented strand board Use to build energy-efficient structures Extensively used in Canada, Europe, Japan and now in Australia.

9 Qualities of Cross Laminated Timber CLT Energy Savings Concept Solid wall panel vs. open framing Minimum clearances for openings Low Thermal Transfer Less insulation needed Accommodates Rain Shield façade technology Durability

10 Qualities of Cross Laminated Timber Sustainability Certified Timber Application High CO2 sequestration Acceleration of CO2 sequestration by volume Application offsets energy consumption Application offsets CO2 off gas from steel, glass, concrete, plastics, etc. Re-Use / Second Life / Recycle / Bio-Mass

11 Advantages of Using Cross Laminated Timber COST EFFECTIVE Use of Southern Yellow Pine more economical than present use of Spruce and Fir. Southern Yellow Pine grows up to 3x faster than other species currently being used in the production of CLT. Use of relatively low value sideboards of a log having quality grades of #2 and #3 can be used in production. Rapid on-site erection and fewer construction delays due to prefabricated elements. Fast and dry installation, immediate durability. Reductions in on-site waste as wall, floor, and roof elements are pre-cut. Reduction of on-site construction noise by eliminating the use of most saws and hammers. Easier on-site installation of plumbing, electrical, and HVAC duct systems.

12 Advantages of Using Cross Laminated Timber SUPERIOR BUILDING PERFORMANCE Sound Insulation due to the inherent acoustic protection of solid mass elements. Fire Protection due to the resistance to spread and the structural stability of solid wood having significant thickness. Load-Bearing and seismic strength. Successful testing and research has been conducted in Japan. Dimensional Stability. Multi-layer slab effect, shrinking and swelling negligible. Air Tightness and Thermal Benefits. Ambient room temperature is maintained with approximately one third the heating and cooling energy. Visible Quality Opportunities. CLT can be sanded or planed and left exposed. Living Space Comfort. Insulation properties moderate temperature and humidity.

13 Advantages of Using Cross Laminated Timber LOW ENVIRONMENTAL IMPACT Low Carbon Footprint because wood products store carbon and take little energy to produce. Carbon Neutral Buildings wood contributes to overall neutrality because more carbon is removed from the atmosphere by the growing tree than is emitted during the process of transforming it into a product. This means wood products carry a carbon credit which helps offset the carbon Debt imposed by other building materials. Safe and Healthy Environment. Use of wood adhesives that are free of toxins assures there is virtually no off-gassing of pollutants into the atmosphere or indoor environment. The use of CLT construction will provide a cleaner, greener, faster, and financially beneficial alternative to standard concrete construction used today. CLT building shells are 10-50% cheaper than their concrete alternatives for the market segments considered.

14 Advantages of Using Cross Laminated Timber PANEL CONFIGURATION The basis for the cutting is formed by the cutting plans of the client (AKA: Formatting). Factory cutting of panels takes place using state-of-the-art CNC technology. Upon request, and with appropriate equipment, the panels can also be cut by the relevant construction company. The size and thickness specific to the need of the project. A typical panel is 8 feet wide and 12 feet long. But, are available in widths up to 14 feet and lengths of 50 feet with depth ranging from 3 to 12 inches. Window openings and routing of electrical runs are pre-cut to precise dimensions.

15 Advantages of Using Cross Laminated Timber PANEL ASSEMBLY Panels arrive at the site pre-cut, equipped with a lifting harness, and ready for immediate installation. Panels arrive in the sequence of construction.

16 Advantages of Using Cross Laminated Timber PANEL ASSEMBLY Easy assembly of CLT components with minimal skilled labor and equipment.

17 Advantages of Using Cross Laminated Timber PANEL ASSEMBLY Depending upon the scale and time schedule, most projects require a crane operator, a Master Carpenter, and two to three framers.

18 Advantages of Using Cross Laminated Timber PANEL ASSEMBLY Precision cut in the factory, CLT panels are used for elevator shafts. Panels can be set plumb and true so that elevator rails do not need shims or spacers.

19 Advantages of Using Cross Laminated Timber PANEL ASSEMBLY Several options for the installation of electrical and plumbing are available. Aside from providing conventional framed walls, conduits and piping can be pre-cut into the panels, cut or core drilled in the field, or concealed in panel connection joints.

21 Advantages of Using Cross Laminated Timber FIRE RESISTANCE In a fire, a solid wall of timber will benefit from protection of a charred layer and therefore does not deteriorate in the same way as a stud or joist. Depending on the thickness of the panel, fire protection classification of ½ to 1 hour are available without the use of any fire resistant covering. Through layered construction using fire treated gypsum wall board, greater fire resistance can be achieved. Being CLT panels are solid, there are no openings for fire to transverse once the finish material resistance fails. The burn rate of a bare timber panel is less than 7 mm per minute. A timber beam will retain structural integrity longer than a steel beam, which loses strength above certain temperature and buckles.

22 Advantages of Using Cross Laminated Timber SEISMIC RESISTANCE: A seven story mock-up building has been erected and tested in a Japanese laboratory, subjecting it to a simulated 7.2 magnitude earthquake. Only minor damage occurred. To see a video of this test, go to YouTube.com and search for Kobe Earthquake Test. SPECIAL CONSIDERATION: After the seismic test, this building was dismantled, shipped back to the owner, and reassembled for use as student housing. Just another example of a practical Sustainable Building System.

61 A Case Study using Cross Laminated Timber Waugh Thistleton Architects & Techniker Engineers The Stadthaus 24 Murray Grove, London Comprising both private and affordable housing, The Stadthaus provides twenty nine apartments, ten of them being affordable units. The entire nine storey panel structure was assembled in 27 working days by a four man crew using powered hand tools and a mobile crane. Timber absorbs carbon throughout its natural life and continues to store that carbon when cut. The fabric of The Stadthaus tower stores over 300 tons of carbon. The total vertical settlement for entire eight floors of timber panel framing was only ¾ of one inch. The exterior façade consists of over 5,000 painted wood fiber panels, and are referred to as a rain shield. Photography by Will Pryce
