We are honored and thrilled that the Q21 mixed-use project in NW Portland was a recent recipient of the Structural Engineers Association of Oregon (SEAO) 2017 Excellence in Structural Engineering Award for a New Building Over $10M. Designed by YBA Architects and constructed by Andersen Construction Company, Nishkian Dean served as the Structural Engineer of Record on the project.
SEAO is a nonprofit organization that works to educate the design industry and the community at-large on structural engineering topics, and provides a valuable forum for structural engineers to interact throughout Oregon.
“We would like to thank SEAO and the awards committee for this honor and we appreciate the continuous efforts of the organization to educate our members and strengthen our industry. We also want to thank the entire Q21 project team and especially YBA Architects for selecting us as the Structural Engineer for such a fun and challenging project.”

Located adjacent to the Conway District at NW 21st & Quimby in Portland, the 7-story, 202,200-SF project provides 162 living units, a courtyard, offices, parking, and ground-floor retail. The mixed-use project consists of two 3-story wood-framed residential buildings separated by a courtyard, all of which is situated above a two-level post-tensioned concrete parking structure that is partially below-grade.
The two buildings are connected directly to a seven-story post-tensioned concrete structure that includes residential units at the upper levels, an office floor level, and retail spaces at the ground floor. The concrete structure’s lateral force-resisting system consists of reinforced concrete shear walls, and a seismic joint was detailed to separate the wood and concrete buildings where they adjoin.
A one-story retail space extends off the north side of the structure, and 8 two-story townhomes occupy the ground level along the building’s south side. The project is highlighted by three-story double-tapered steel columns at the main entrance that form an “XXI” shape to symbolize the project name and street number location. These specialty steel columns were constructed with two tapered dodecagon (12-sided) steel sections welded together at the column midpoint to form a double-tapered member. A tapered cantilevered post-tensioned concrete beam spans the top of the steel columns to support four stories of structure above.
One of the most unique and challenging aspects of the project included preserving and modifying the 35-foot tall existing concrete tilt-up wall panels from the existing warehouse building on the site. The team incorporated the panels into the architectural and structural design as a non-structural exterior wall element to preserve the heritage of one of the early buildings that Andy Andersen, the founder of Andersen Construction, constructed and to promote the conservation of materials. This effort was significant and meaningful for Andersen Construction now that the family-owned business is being led by its third generation.
The existing concrete wall panels were cut, reinforced with steel backing and fiber reinforcement, and temporarily braced during construction. A few of the panels were lowered and transported to off-site storage to allow for site access during construction. Nishkian Dean provided full engineering support for this entire process during the initial phase of construction.
“The project afforded many opportunities for creative solutions to meet an ambitious and innovative vision. It was an honor to be a part of the cutting-edge design team on one of the first two-story podium structures in the City of Portland. We are very proud to receive such a prestigious award and grateful to SEAO for establishing a platform to recognize excellence in structural design.”

The Silicon Valley Business Journal recently announced the winners of its 2016 Structures Awards competition, and seven Nishkian Menninger projects were recognized. Our Central and Wolfe project in Sunnyvale won the Deal of the Year award. 1400 Page Mill project in Palo Alto won the Green Project of the Year. Centerra Apartments and Indigo Apartments both won in the Market-Rate Residential Project category. The Menlo Gateway project and the University Square project both won in the Speculative Project category. Splunk at 500 Santana Row won in the Office Deal category. Nishkian Menninger is proud to team up with the various project teams for these seven projects.
Engineering News Record magazine (ENR), the leading engineering industry publication released its national “Best of the Best Projects” winners for 2015, designed to identify the pinnacle of design and construction achievements in the U.S. among projects completed between June 2014 and June 2015. Nishkian Menninger’s 100 Van Ness project won the “Best of the Best” in the Residential/Hospitality category in the nation, and is one of 20 “Best of the Best” projects profiled in the March 14 issue of the magazine.
The American Concrete Institute (ACI) has just awarded the structural and construction awards for 2015 to the Centerra project in San Jose. Nishkian Menninger, and Webcor Builders were recognized for constructing approximately 615,000 square feet of concrete floors in 9 ½ months. The ACI described this achievement as a great example of what the design build process can bring to a structure of this magnitude. The 22 story apartment complex is located near the SAP Center in San Jose and is almost ready for its first residents to move in.
The Prescott Apartments placed in the top three in the outstanding Private Buildings category at the Daily Journal of Commerce’s TopProjects 2014 awards show last May 15th.
This mixed-use project is comprised of 155 apartments and six commercial spaces surrounding a beautiful courtyard. It is in a prime location in the Interstate Corridor of North Portland. Since it is adjacent to the light rail line and has easy freeway access, it’s a great building for commuters in a growing community. The impressive rows of windows were made possible in the structural design by using rigid wood frames, moving all of the plywood shearwalls into the interior of the building. Nishkian Dean is proud to be part of the team that contributed so much time and energy into making this a TopProject award winner!
Located in the Crow’s Nest development at Sugar Bowl Ski Resort in Tahoe, California this 5,600-square-foot, three-story, unique ski-in/ski-out chalet is truly a one-of-a-kind custom home. Nishkian Monks PLLC participated in the project as the structural engineer of record, working directly with San Francisco-based architectural firm Baldauf Catton Von Eckartsberg/BCV Architects, and general contractor Mt. Lincoln Construction of Truckee, California. Situated in the Sierra Nevada mountain range where maximum expected design snow depth is 16 feet – equating to 380 pounds per sq.ft. of snow weight, construction of this luxury residential building posed challenges due to the site and program constraints. Additionally, the site is located at one of Sugar Bowl’s highest reaches – higher than many of the resort’s ski lifts, and situated in a region of high seismicity. BCV Architects challenged Nishkian Monks with designing a multi-folded, double sloping plane roof with oversized overhangs out of wood framing that could support the extreme roof snow loads. Through numerous design iterations and collaboration with BCV, Nishkian Monks successfully achieved a structural design for BCV’s striking exposed wood purlin roof. The roof purlins were arranged in such a fashion so as to emanate from the center of the chalet when viewing the house from any side.
