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.”

1201 Tennessee is a new mixed-use residential development located in the heart of San Francisco’s Dogpatch neighborhood. Historically industrial, the Dogpatch district has experienced extensive residential and commercial growth since the 1990’s. 1201 Tennessee sits on land that was once a 1,500-foot long building used for production of rope by the Tubbs San Francisco Cordage Company. The industrial nature of the neighborhood is represented by a silo aesthetic along Third Street while San Francisco’s residential, Victorian architecture is represented along 23rd Street.
Developed by AGI Resmark the apartment complex offers 259 mixed-income units with ample parking and retail space on the ground floor. The project also includes 34 affordable units for families earning 55% or less of the area’s median income. The complex amenities include bicycle parking, shared work spaces, a roof deck, and a protected courtyard with green space. 1201 Tennessee is adjacent to both the MUNI rail system and Caltrain, making it accessible for people working in San Francisco or Silicon Valley. The structure of this project is five stories of wood construction over one level of concrete with a mezzanine level, all supported on a pile foundation system. Concrete and wood shear walls provide the lateral force resisting system.
Fougeron Architecture has designed the apartment complex collaborating with general contractor Devcon Construction, and structural engineers Nishkian Menninger in San Francisco and Nishkian Monks in Bozeman. Our San Francisco office designed the concrete substructure while our Bozeman office designed the wood superstructure.

As spring gives way to summer, construction crews are making swift progress at Yellowstone Club Core Village’s ongoing, $312 million mixed-use base village project to add more amenities for its growing list of members. Andy Sandoval, GE Johnson Construction Company’s project superintendent, sheds light on the progress being made at the largest construction project ever to take place in the Rocky Mountain region.
“The precast erection from Stresscon had a great month by erecting 556 pieces. The total piece count now stands at 2,762 pieces erected and 62% complete for the total project. To date, 768 precast deliveries were made travelling from Colorado Springs to Big Sky, MT. That’s a round trip of 1,617 miles or a total 1.2 million total miles of trucking just to get the team to this point of the structure. The largest piece of precast concrete for the project weighing approximately 83,000 pounds was installed this past month. Our GE Johnson/Jackson and Schmueser concrete crews also eclipsed a nice milestone in the last month by placing our 10,000th cubic yard of concrete for the project. Earthworks group has also continued backfilling the foundations within the building footprint as well as the exteriors of the building right behind A+ Waterproofing installing the foundation waterproofing. Encore Electric has continued doing the in-slab rough in, overhead rough-in and underground work for the project. Thus far, Encore has installed over 30,000 feet of conduit for the project. That’s 5.7 miles of conduit! Encore Electric and Apollo Plumbing and Mechanical have expedited their work by each pre-fabricating over 3,000 man-hours worth of product at the Bozeman Hub facility during the winter months inside a controlled environment saving the project both time and money.
In Area 1, True North and Sowles completed the Area 1 steel structure and Rooftop Solutions has completed the roof dry-in for Area 1. This has allowed Advanced Fireproofing to begin spraying the steel structure on Levels 3 and 4. Safway Scaffolding is nearly complete installing the scaffold around the Area. This has allowed SCS Drywall to complete a substantial amount of exterior framing and sheathing on the levels below. Patriacca Construction is right behind them installing the exterior envelope and aluminum clad wood windows. Patriacca has also been busy in our Bozeman Hub fabricating the exterior timbers to prepare them for installation. Gallegos Corporation is busy in this area installing the steel lintel angles and will begin installing stone in the next two weeks. The first elevator should be ready for construction use by the end of the month.
In Area 2, precast erection has been completed on the East side. The West side of this area is currently getting garage walls and shafts completed with the CMU while Paradigm is continuing to place the concrete slabs on the West side through Level 3. Area 2 is nearly fully connected to Area 3 making the building perimeter of the structure easily defined visually. The conventional cranes are now setting in Area 4 and beginning to work their way out of the project. As the cranes move, the foundations in Area 4 is rapidly progressing and completion is anticipated to be as scheduled.
Area 5 and 6 are also off to a great start. In fact, the Area 6 (The CUP), is the first Area to have exterior stone installed. The CUP has also completed all the structural ramps and Superior Waterproofing has completed the hot-applied waterproofing and protection board and foam on the upper level. 4G has installed the hydronic snowmelt in the topping slab for the ramp and it will be placed next week. Inside the CUP, generators, boilers and other major infrastructure are in place and being hooked up to be the lifelines of the project by this coming fall/winter. Western States has installed the fire protection systems inside and the waterproofing and exterior backfill are in progress around the perimeter. Sime has now completed the work around the pond to allow the CUP and the project to connect to the Yellowstone Club infrastructure. Area 5 is busy getting the framing and MEP rough-in going on the interiors. Steel Erection is continuing on the North side of this area and the South side began metal decking for the roof. The Area 5 exterior scaffolding is going into place and the exterior framing and sheathing have begun and are right behind the scaffold erection.
We are now over 300 employees on site and will begin running the 6th daily bus on June 19th from Bozeman to the jobsite. This project represents employees from 38 states boasting multiple nationalities and who can collectively speak over a dozen languages. The ages of the men and women on site vary from the ages of 18 through 74 years. Our entire team here have shown through their efforts and actions thus far that construction may be the greatest team sport!”

Formerly a storage site, the 3.3-acre lot at 100 and 150 Hooper Street in San Francisco just off of 7th Street and Mission Bay Dr. is being developed into office space and manufacturing space. Zoning requirements in San Francisco’s Design District dictate that one-third of the space must remain industrial space. The ground level of each building has been designed as such. This development will be ideal for a technology company requiring production space. 100 Hooper will feature an “urban farm” and solar panels on the roof.
100 Hooper comprises the majority of the site’s area. 100 Hooper is two long buildings connected by two “skybridges” at the second and third floors. The two buildings total 427,255 square feet of leasable space. Both buildings are four stories of concrete construction, utilizing shear walls and post-tensioned slabs. The two skybridges are steel, utilizing concentric braced frames as their lateral force resisting systems. The skybridges are connected to the buildings at one end by a frictionless surface, allowing the two buildings to move independently in a seismic event.
Developer Kilroy Realty Corporation collaborated with design architect Pfau Long Architecture, and implementation architect Forge Architecture on the design of this new PDR development in the city’s Potrero Hill. The general contractor is DPR Construction, and Nishkian Menninger served as the structural engineer for 100 & 150 Hooper Street. For photos and more information about the project and development, please visit 100 Hooper.

This 7-Story, 202,200 square feet project with 162 living units located adjacent to the Conway District at NW 21st & Quimby in downtown Portland will be ready to rent out units starting next month. Nishkian Dean proudly worked with YBA Architects and Andersen Construction Company on this unique and challenging project. The project is highlighted by three-story tapered steel columns at the main entrance that form an “XXI” shape to symbolize the project name and street number location. These specialty columns were constructed with two tapered 12-sided steel sections welded together at the column midpoint to form a double-tapered member. A cantilevered post-tensioned concrete beam spans across the tops of the tapered steel columns to support four stories of structure above.
The Academy Square project is a new $300 million mixed used project being developed by Kilroy Realty Corp. and is located in the heart of Hollywood. The project has a 150,000+ square-foot footprint, the size of an entire city block, and over one million square-feet of office space. It is being designed with House & Robertson Architects, Inc. serving as the Executive Architect for the commercial portion, GBD Architects serving as the architect for the residential portion and Shimoda Design Group serving as the design and landscape architect.
The Rowan, located at 346 Potrero in San Francisco in the Potrero Hill neighborhood will complete construction by the end of 2016. Designed by Handel Architects for Trumark Urban, and constructed by Build Group, the Rowan includes a mid-rise residential building that will house parking, retail areas and residential units. The building stands 9 stories above grade with one level of both storage and utility space. The building will open with 70 residential condominium units, 5,000 square feet of open space and 41 parking spaces, with a basement level for parking, storage, and utility space. The total building area is approximately 88,000 square feet. There are also two outdoor common areas, one on the second floor and one on the ninth floor.
The Pierce is a new landmark structure bringing 232 luxury apartment and 8,730 square feet of retail space to San Jose’s South of First Area (SoFA) district. Project owner, Sares Regis, together with Steinberg Architects envision that this project will help to revitalize the area and become the gateway to downtown San Jose. In 2014, The Silicon Valley Business Journal awarded The Pierce “Best Mixed-Use Project.”
Standing seven stories tall – five stories of wood framing over a two-story concrete podium – The Pierce is an exceptional project from an engineering standpoint, as well. In order to maximize exterior window openings and allow for offset exterior walls, the wood frame portion of the building was designed using rigid diaphragm analysis. Traditional wood frame design uses flexible diaphragm analysis where lateral forces are distributed evenly between the short exterior shear walls and the long interior corridor walls. Using a rigid diaphragm approach, however, Nishkian Menninger was able to eliminate the need for exterior shear walls, instead distributing the lateral forces to the longer and more effective corridor and unit separation walls. Having been approved by the San Jose building department, the Nishkian offices are now applying this technique to other multi-unit residential buildings throughout the Bay Area.
During the past 18 years, Buckling-Restrained Braced Frames (BRBFs) have been used extensively in the United States as part of the seismic force-resisting system for buildings in regions of high seismicity. One of the first new construction projects in Montana that employed BRBFs was the Mill Street Lofts building located in north of downtown Bozeman. The Mill Street Lofts building construction was the first phase of a multi-phase urban renewal projects to revitalize an older, industrial sector of the city. The vision that the owner/developer, Mill District Partners, LLC had for the greater project was a main street lined with buildings, which paid tribute to the industrial sector while creating the look and feel of a downtown main street. Comma-Q Architecture, Inc. took on the role as lead designers and project managers for this project. Nishkian Monks served as the structural design consultant providing development and design of the structural system, construction administration, and special inspection of the building design collaborating with general contractor Martel Construction, Inc.
The transformation of a former pea cannery in Bozeman’s Cannery District on the northeast end of town into a four-story office/mixed-use facility is almost complete. Construction crews are hard at work throughout the site, finishing details and completing those areas not yet ready for public access. The developers, Cannery District Partners LLC, with Comma-Q Architecture, Langlas & Associates, and Nishkian Monks, hope to provide a new mixed-use and commercial/retail space to an up and coming live-work neighborhood.
Koreatown, a neighborhood in Central Los Angeles centered near Eighth Street and Western Avenue, is the most densely populated and diverse district by population in Los Angeles County, with some 120,000 residents in 2.7 square miles. The neighborhood lies near mass transit hubs including the Red Line and new Purple Line, 3 miles west of downtown Los Angeles, 4 miles south-east of Hollywood, 12 miles from Santa Monica Beach and 16 miles from Los Angeles International Airport. The boundary for Koreatown is approximately from Beverly Boulevard to the north to Olympic Boulevard to the south and S. Wilton Place from the west to S. Virgil Avenue to the east. And development is booming!
The surrounding areas are also actively growing; there is a resurgence of activity in residential, retail, and office in Downtown LA, the Westside is as strong as ever, and Miracle Mile is realizing huge growth in entertainment clients. Koreatown is the hub of all of these areas and begs new development as urbanization moves people from the suburbs closer to where they actually work. The population is looking to cut down their commuting time and carbon footprint and live somewhere with more infrastructure and amenities.
The Nishkian Chamberlain group of Consulting and Structural Engineers are currently collaborating with developers and architects on several new Multi-Family and Mixed-Use development projects. Here is a sample of a few projects we are currently working on:
Bryant Street Development in San Francisco, CA
The Bryant Street development, currently under design, is a collaboration with the owner, Nick Podell Company and the architect, BDE Architecture. The development consists of razing the majority of an entire Mission District block and constructing nearly 300,000 square feet of Mixed-Use development. The new building consists of a six-stories with two distinct architectural styles, 274 apartments, 4,300 square foot ground floor retail space and underground parking for 160 cars and 145 bikes all fronting Bryant, 18th, and Florida Streets. Special structural considerations include: a creative analysis approach of the structures lateral force resisting system to reduce the cost of construction by eliminating the need for exterior shearwalls; a post–tensioned concrete podium first floor slab – supporting first floor park- like landscaped setting with large trees and planted areas; a “Mat Foundation” system to eliminate the use of extremely large spread footings and minimize differential settlement due to varied soil conditions across the site; the design of an accessible roof top dining lounge area, BBQs, large wood arbors and trellises, and planting areas. The project is currently in design with construction slated to begin in 2015.
Nishkian Chamberlain is proud to be working with Kollin Altomare Architects on a new mixed-use development along the Valley Boulevard Corridor in San Gabriel, California.
Crossing 900 is the largest office project planned for Redwood City’s downtown area. The 300,000 square foot development boasts a planned LEED Gold rating, views of the bay and peninsula hillside, parking for over 900, and 5,000 square feet of retail or restaurant space. All will be located a short walk away from the Redwood City Caltrain Station, on a 2.3-acre site formerly occupied by a parking lot. The project developers, Kilroy Realty and Hunter/Storm Properties anticipate the office space for over 1,000 employees will be desirable and fill up fast when construction is completed in 2015.
Redwood City officials hope to bring new businesses and employees to the downtown area, and to be as environmentally friendly as possibly when doing it. With over 1,000 new residential units also planned for the downtown Redwood City area, the hope is for people to live and work in the growing area.
Five years ago in the morning of March 5, 2009, a gas main explosion and fire rocked the snow-covered Downtown Bozeman, destroyed five historic buildings and businesses on the north side of the 200 block of East Main Street, and killed one young woman. City building officials immediately worked with Nishkian Monks engineers to set up two-person evaluation teams to assess over 50 buildings in the six blocks affected by the blast, and cleared most of them for limited occupancy allowing the people whose homes and livelihoods were affected to start cleaning up and moving forward. Five years later, a lot has been accomplished in reconstructing the area and Nishkian Monks continues to work with the revitalization efforts.
Portland, OR – As part of the North Interstate Corridor Plan adopted by the Portland City Council in 2008, The Prescott is one of the five major developments meant to contribute to the urban “boom” in North Portland, and to set the precedent for future growth in the area. Sitting regally on the corner of Interstate Avenue and Skidmore Street, The Prescott mixed-use offers not only 9,500 sf. of ground floor retail space, but 155 market-rate apartments, and an underground garage with 111 parking stalls. Many of the apartment patios look out over the Willamette River toward downtown Portland and the West Hills with scenic views of Mt. Hood and Mt. Rainer in the background. The Prescott is meant to be the focal point of this gateway station, and Myhre Group Architects can be thanked for the creative design that truly embraces the future theme of the Interstate Corridor.
