MASS TIMBER EXPERTS
DCI’s engineering teams have completed over 180+ projects utilizing mass timber in the United States. We participate in regional conferences and exchange ideas with mass timber industry leaders in order to pioneer the successful adoption of mass timber through several prominent North American projects.
We draw upon our engineers’ collective knowledge of the industry and mass timber’s various products and applications to serve as a resource for the design team, contractor, and owner as we move from conceptual-level studies, through the development of construction drawings, and into construction administration. We have experience employing mass timber in many different structural assemblies to optimize either cost, performance, or enhance aesthetic qualities—often with mass timber, we are able to exceed expectations on multiple fronts.
Mass timber is best suited for a range of projects types --from office, to retail, multi-family, K-12, higher-education, and single-family—and DCI Engineers has experience working with each of those types, in addition to most others. We are well-versed in the use of CLT for floor and roof applications, lateral force resisting systems, hybrid and/or composite wood and concrete structures, and we understand the importance of properly detailed connections. Our experience includes using glulam or steel frame to support different types of mass timber floor plates including CLT, NLT, and DLT. DCI completed the first of its kind testing of mass plywood panels (MPP) and is helping lead university research for point supported analyses of MPP to increase the product’s acceptability to building officials. This testing led the way for the two tallest MPP residential towers in the world. By having projects across America using all of the latest timber technologies, DCI is able to help provide our clients with the most cost-conducive solution while the project still reaps the benefits of sustainability, biophilia and aesthetics.

LEED EXPERIENCE
ARROWHEAD PHARMACEUTICALS, Verona, Wisconsin
LEED v4.1 Silver - (3) Points for Building Life-Cycle Impact Reduction
This project is a new pharmaceutical office building consisting of approximately 129,200-GSF over 5 levels. The construction team procured low carbon concrete containing Type IL Portland Limestone Cement which demonstrated environmental impact reductions when compared to the North Central regional baseline. Global Warming Potential reduced by 12% or 587 metric tons of CO2e which equates to the GHG emissions associated with 130 gasoline-powered vehicles driven for one year.
WILMINGTON COLD STORAGE, Wilmington, North Carolina
LEED v4 Gold - (3) Points for Building Life-Cycle Impact Reduction
This development is a new two-story, 288,174-GSF cold storage and distribution center. The design team utilized insulated metal panels in lieu of traditional concrete tilt-up panels to demonstrate environmental impact reductions. Global Warming Potential reduced by 15% or 1,180 metric tons of CO2e which equates to the carbon sequestered by 1,400 acres of U.S. forests in one year.
CLACKAMAS COUNTY COURTHOUSE, Oregon City, Oregon
LEED v4.1 Gold - (3) Points for Building Life-Cycle Impact Reduction
This project is a 241,000-GSF, six-story courthouse building. Efforts to reduce environmental impacts include: rearranging the column grid to cantilever the slab along one edge to eliminate a row of columns; coordinating a simplified formwork solution to reduce slab thickness by 1" for approximately 75% of the floor plate; utilizing mass timber canopy at the main entrance of the building in lieu of concrete; implementing performance-based concrete specifications, EPD requirements & GWP limits. Global Warming Potential reduced by 24% or 2,440 metric tons of CO2e which equates to the GHG emissions associated with 540 gasoline-powered vehicles driven for one year.
JCI ENGINEERING CENTER, Glendale, Wisconsin
LEED v4.1 Gold - (5) Points for Building Life-Cycle Impact Reduction
The JCI Engineering Center is a two-story, 103,736-GSF lab facility. Instead of pursuing entirely new construction, this renovation utilized the roofing, steel framing and foundations from the existing building to meet the needs of the expanded building program. Global Warming Potential reduced by 12% or 313 metric tons of CO2e which equates to the CO2 emissions from powering 60 homes electricity for one year.

1510 WEBSTER STREET, Oakland, CA
This 19 story mixed-use high-rise building in Oakland consists of 182 apartments, retail, commercial spaces, and a covered public plaza. 1510 Webster Street became the first high-rise in the United States to utilize point-supported mass timber and mass plywood panels (MPP). Early involvement in the conceptual design phase allowed DCI to advocate for mass timber over traditional concrete framing which not only resulted in embodied carbon savings but provided cost and scheduling savings that helped the owners achieve affordable housing goals. The mass timber building’s structure & enclosure demonstrated 5% less embodied carbon than the all-concrete scenario and 49% less embodied carbon when considering anticipated biogenic carbon storage during the lifetime of the building.
THE ARTISE, Bellevue, WA
The Artise will be a 25-story office tower in Bellevue’s central business district appealing to high-tech businesses and professionals. The 1,040,000-sf tower will consist of a steel framed gravity and lateral structure with buckling restrained mega braces and steel moment frames.
By utilizing an innovative lateral system along the perimeter, DCI saved an estimated 25% of steel tonnage in the structural frame. Additionally, because there were no traditional concrete cores or interior braced frames, the parking plans were optimized to eliminate an entire belowgrade level. By eliminating approximately a quarter of the steel framing required for a traditional steel-framed office layout, the project reduced its embodied carbon by an estimated 11% as well as substantial cost savings.
PROJECT EXPERIENCE
1510 WEBSTER STREET
Oakland, California
1510 Webster Street is the tallest, masstimber building in California. The timely construction of 1510 Webster Street aligns with the updated California Building Code, allowing for taller mass timber than ever before. The 19-story multi-family residential building provides 182 units and 15,000-sf of office and retail space on the ground floor. A landscaped garden is situated on Level 7, while the high-rise rooftop provides a trendy rooftop lounge and amenity space.
1510 Webster Street is also the first high-rise in the United States to utilize point-supported mass timber and mass plywood panels (MPP). This unique system required custom, laboratory testing of the MPP to determine the punching shear capacity at the point supports, as well as validate the deflection and vibration performance. The MPP is less expensive than typical cross-laminated timber (CLT) and also provides greater strength and stiffness per equivalent thickness. In addition to designing the first ever mass timber high-rise in California, DCI Engineers also helped the team save significant cost on the foundation and temporary shoring system by repurposing the basement walls from the existing structure that was located on the site.

1 DE HARO
San Francisco, California
This 170,000-sf office building is the first of its kind in San Francisco. With three levels of Type IV framing over two stories of Type I framing, the building features approximately 100,000-sf of Type IV heavy timber framing, including cross laminated timber (CLT), glulam beams and columns and a timber concrete composite floor. The building utilizes a mixed construction method (Type IV over Type I) in order for the client to maximize the assembly area at the roof for tenants.
The project went through an extensive pricing exercise that spanned almost a year where DCI worked closely alongside the contractor to price concrete, steel and mass timber options. In the end, the mass timber option was agreed upon by the design team for its savings in both schedule and structure, along with its sustainability aspects. By selecting a mass timber building, the design team was able to save 40% in the number of piles required at the foundations for the project.
CHANNEL HOUSE
Oakland, California
Part of Oakland’s Jack London Square waterfront, Channel House is an eight-story, mixed-use, multi-family complex with 333 living units, 2,400-sf of ground level retail space, landscaped courtyards, communal gathering areas, outdoor terraces, and fitness center. The development includes five stories of Type III wood-framing over three stories of Type 1 concrete with posttensioned concrete slabs supported by a combination of concrete columns and shear walls. DCI’s use of a straight wall system for the Type 1 portion minimized construction costs while accommodating architectural layout, specifically for the 10-inch thick walls in the living units, which limits projections and maximizes floor area.
One of the architectural features of the project is a double height lounge area space located on the southwest corner of Level 4. In order to economically achieve this design feature, DCI evaluated mass timber, steel, and concrete options. Through coordination with the architects, the team determined a steel framed option combined with a CLT floor plate above the amenity areas provided a cost effective solution.

FIRST UNITED BANK
Sherman, Texas
The First United Bank in Sherman, Texas is a newly constructed two-story commercial building totaling 37,000-sf. The bank includes drive-thru teller features, a vault, offices, and a reclaim water system for irrigation purposes. The mass timber, steel, and concrete framing system provides an open floor plan, natural lighting, and exposed wood architectural elements.
DCI was the primary structural engineer of record and designed the prefabricated roof panel system supported by long-span glulam beams and columns; CLT shear walls and supplemental wood sheathed shear walls to resist lateral loads, cold-form steel framing for non-load bearing walls; and coordinated concealed connections via pre-engineered timber hangars and connector products. Extra attention was devoted for the exposed connections and column splices throughout the design and construction.
CEDAR SPEEDSTER
Seattle, Washington
Cedar Speedster is a newly constructed, mixed-use commercial building comprised of mass timber material. The timber structure honors the neighborhood’s historic industrial and lumber business influence once rife in Fremont. The three-story building includes 5,000-sf of retail, 10,000-sf of below-grade parking, and above-grade office levels. Prefabricated glulam columns and steel knife-plate connections were installed to accommodate uninterrupted columns from the ground floor to the roof level. This configuration of continuous columns minimizes timber shrinkage. DCI Engineers designed the custom beam and column connections for timber, concrete, steel, masonry, and foundation details.
DCI and the architect determined the strategic positioning of glulam girders for HVAC systems and utility piping to run tightly along the ceiling to preserve views and daylighting below the structures, which enhance the tenant’s overhead space. The engineers opted for a concrete shear wall core that allowed the architect to open up the perimeter of the storefront area.

KEY FEATURES
LEED® Gold status
DCI provided structural design services for 38 Davis, a six-story, mixed-use building located in Portland’s Old Town Historic District. The L-shaped, wood-framed building is comprised of heavy timber construction over onestory concrete podium slab, which is a post-tensioned flat slab supported on concrete columns with concrete shear walls. Commercial retail/office spaces are located on the ground floor.
Levels two through four, which are dedicated to commercial/office space, are framed with glulam beams and columns, and offer an open office design. The upper two levels of residential units, which include affordable housing options, are framed with TJIs over glulam beams and columns. Concrete topping over levels two through six act as a diaphragm and mass to achieve the acoustic rating.
The building’s design was approved by the Historic Landmarks Commission in December 2014 and has earned LEED® Gold status. One of its most notable features includes gray water reclamation, which uses shower water runoff from the apartments to flush toilets in the office spaces.

NEW URBAN HIGH SCHOOL
Oak Grove, Oregon
North Clackamas School District built a new two-story facility with 23 classrooms for the New Urban High School and renovated a separate, existing gymnasium. The new two-story building has a light-filled commons area, media center, art room, and technical education classroom. The building features ADA accessibility, a missing component in the original school constructed during the 1950s.
DCI Engineers provided both structural and civil engineering services for the project. The structural team proposed seismic improvements for the main building and gymnasium. For the new building, they designed the foundation, framing, stud and shear wall configuration, and structural details. For the gym, the team designed new shear walls; strengthened the trusses with post tension cable; and added fasteners to interconnect the roof walls and foundation.
The civil team evaluated the existing site conditions and developed the site demolition, erosion control, grading, stormwater, and utility plans. They coordinated documents to relocate parking; to replace the gravity storm line with new vegetated water quality and detention facilities; and to devise on-site and off-site improvements.

NORTHLAKE COMMONS
Seattle, Washington
Northlake Commons is a two-tower, five-story life science-ready office building with connecting floor spaces. The mass timber office building is supported on three levels of below-grade parking; 9,500-sf of retail space; 27,000-sf of warehouse space; and 64,500-sf of outdoor space.
DCI designed the concrete parking levels and the timber framing to support future office and life science requirements; configuring column and girder layouts to optimize the balance of future requirements and market needs with current construction variables. The lower two levels are currently lab-ready and have been designed to meet anticipated floor load and vibration requirements. The upper floors are designed for office floor loading and can be upgraded during tenant improvement work for higher load and vibration requirements where needed.
BELLINGHAM PUBLIC SCHOOLS ADMINISTRATION BUILDING
Bellingham, Washington
Situated on a sloping site, the new Bellingham Public School Administration Building provides upgraded administrative, conference room and support facilities within a beautiful mass timber structure. The project capitalized on Type V-B construction, using light-frame exterior walls and shear walls with a glulam post and beam interior framing system that allows for maximum future flexibility, along with an exposed CLT floor plate and roof plate system. One end of the building is also designed as non-load bearing in its entirety for a possible future expansion of the structure.
DCI pursued a “use the materials where they make sense” approach. For example, the long span conference spaces use steel beams as a more efficient use of material. The team also utilized concrete shear walls to limit the length of shear walls needed to maximize the future flexibility of the spaces.
The building is oriented around the Community Space, the heart of the new development. A grand ‘feature stair’ encourages movement and provides a welcoming pathway to staff and visitors alike. This central space is bordered by various public program elements, including a cafe, informal meeting areas and an Early Learning Center.
