Orange Line – Swift Bus Rapid Transit

As part of Washington State’s first bus rapid transit (BRT) line, the 11-mile Orange Line route connects potions of Snohomish County along with the cities of Lynnwood and Mill Creek. Otak led the design and permitting while also providing construction engineering support for this transit-oriented development.

Expanding Bus Rapid Transit Corridors and Facilities for Improved Public Transportation

The design of this corridor connects service to Edmonds College, Lynnwood city center, Alderwood Mall, Mill Creek, including four park-and-rides and three future Sound Transit Link light rail stations. Project elements include a new transit center for the western terminus at the Edmonds College, construction of 17 BRT stations along the new Orange Line corridor and one additional BRT station along the Blue Line Swift Bus route, retrofitting five Green Line stations to also function as Orange Line stations, reconstruction of the existing transit center at the McCollum Park Park-and-Ride, and roadway and signal improvements at approximately 14 intersections to improve transit speed and reliability. Otak team efforts include alternatives analysis, preliminary and final design, environmental permitting, PS&E preparation, and jurisdictional coordination and permitting for the proposed BRT stations and termini including all associated roadway, signal, and pedestrian improvements.

Tolt Avenue/SR 203 Central Business District Improvements

In revitalizing the central business district of Carnation, Washington, the reconstruction of four blocks was designed to improve a variety of areas from stormwater and utilities to traffic signage and pedestrian wayfinding. As the prime consultant completing these extensive streetscape improvements, Otak led the design, community engagement, and development of a comprehensive construction sequencing plan to minimize disruption to existing downtown businesses.

A Revitalized Streetscape Emphasizing Pedestrian Connectivity and Low Impact Development

This federally funded project applies a community-character design theme that draws on the area’s history to deliver new streetscape amenities as well as a host of functional streetscape improvements. Unique metal cut-out panels used as banners on street light poles and incorporated into street furniture highlight this theme. The design for core blocks downtown focused on pedestrian connectivity and gathering spaces while underground stormwater quality treatment vaults placed beneath sidewalks function as root-storage, allowing for street trees to be placed within the dense business-district environment. Integrated adjacent to the planter areas are stormwater bioretention facilities creating natural balance with landscape plantings. Use of a depressed-curb intersection design at Bird Street opens the cross-street pedestrian corridor for future festivals and other street events.

Lake Washington Loop Trail

To complete a gap in the more than 50-mile Lake Washington Loop Trail system, this segment also provides improved connections to downtown Renton and Boeing. Beginning with a preliminary design study, the Otak design ultimately adds 2,500 feet of an 11-foot-wide cycle track for bicyclists while updating existing sidewalks for pedestrian access.

Connecting a Bike Trail System and Multimodal Access to a Community Business Hub

After a preliminary design study recommended walkway and bicycle facility concepts for 7,000 feet of regional trail near the Renton airport and Boeing plant, this project moved forward in phases beginning with this 2,500-foot segment. In the resulting design, a cycle track and sidewalk were installed along the north side of Airport Way, and over the Cedar River. Due to limitations in right-of-way along Airport Way, traffic lanes were reconfigured to allow for the new cycle track. The project also included utility improvements, bridge handrail modifications, landscape and urban design, improved pedestrian connections, pedestrian lighting, signal updates, and signage. Otak provided surveying, preliminary engineering, final design, right-of-way plans, and construction engineering support.

How Engineering Impacts More Than the Built Environment

The science of engineering is the backbone of the environment we construct around us, and many people perceive engineering in its most common ways. For example, both civil and structural applications are when engineers are most in the spotlight and is arguably the first thing people think about when considering what “engineering” means. These practice areas are often the most visible because they are physical and affect our daily lives as both participators in the built environment and also as members of society.

“I love being able to see a project come to life. It is quite a spectacular feeling to know I have helped bring someone’s idea into reality.”

Hailey Sibert – Otak Civil Designer

However, engineering can be much more varied than meets the eye, and the practice area is defined by the broader applications that a multidisciplinary approach can have on not only the built environment, but also on the communities that call that environment home.

In this post, we’ll explore the ways in which engineering affects multiple facets of society, and show just how important the intersectional practice is to fully functioning communities.

View of transportation design

Getting People Around, In Multiple Ways

Transportation engineering immediately comes to mind when thinking about the lesser thought applications of the profession. Options for transportation in the built environment don’t just spring up out of nowhere, and the impact that high functioning transportation infrastructure on communities is hard to overstate.

Quality transportation engineering improves how community members get from place to place and serves as a great socioeconomic equalizer. By increasing access to jobs, opportunities, and services through breaking down transportation barriers, engineering directly uplifts disadvantaged groups within municipalities by ensuring everyone gets an equal shot at getting there.

Multi-modal transportation also plays a role here. Communities don’t solely consist of cars, trains, and busses. Designing pedestrian-friendly areas allow neighborhoods to flourish and encourages healthier, more walkable lifestyles among citizens. Greater still, access between point A to point B is improved for those who do opt for public transport, which decreases reliance on cars. This means everything from sustainability perspective, and it’s all made possible through quality engineering that’s designed to move people, not just vehicles.

Using The Natural Flow of Things

The environmental intersections of engineering with purpose are also huge components of quality design. When we envision communities, we design with natural surroundings and not despite them. By doing this, we place an emphasis on low impact development (LID) which gives way to developing green stormwater infrastructure.

The best part about being a civil engineer is building connections. We building infrastructures and improve transportation networks that connect people and communities.

Eva Ho – Otak Civil Engineer

Without a multidisciplinary approach to this type of engineering, the greener aspects of project work may go unnoticed, or natural systems in place may be harmed or interrupted. Instead, engineers can design around habitats by understanding water flow and hydraulics of the site. In this way , water and natural resources engineers play a critical role in making communities not only sustainable for humans, but also more habitable for other forms of wildlife that may exist alongside something out of the built environment.

Helping the Rain Go Away

Quality water resources engineering also helps us answer unique questions about planning and design, including ones in relation to stormwater and surface water management. One might ask themselves, “When the rain falls, where does it go?”

The answer? It’s been engineered to flow through the community in helpful ways. For one, understanding water detention and retention prevents flooding for neighborhoods already in place. Second, it ensures quality of water for communities and natural habitats impacted by the local watershed and stormwater runoff — engineering for the community of life, not just for people.

“My [engineering] work has given me the opportunity to wear many different (hard) hats. I’ve designed cable stay bridges, a variety of buildings, sculptures… every day is an adventure!”

Greg Mines – Otak Structures Engineer

This ultimately helps prevent more vulnerable communities and areas from experiencing the effects of increased or harmful precipitation by injecting climate resiliency into the existing system, something a traditionally structural engineer might not consider. When multifaceted engineers are tasked with a project, they come up with a multi-pronged way of looking at a project that does more than just house, shelter, or get people to work on time.

Finding the Perfect Place for a Project

Engineering helps us answer even more pertinent questions about the built environment and our relationship with it, even before construction begins. So, just what happens on a site before we start building on it? Choosing the right spot to begin work involves a lot more than one would think.

Scrupulous engineering considers all the possibilities in order to find the right place for a project based on a goals and initial design, giving way to the practice of site development. Coming up with creative, practical, buildable, and permittable solutions is the work of engineers as well, and good ones are context sensitive (to cultural and natural resources that exist around a site) before building starts. Design efficiency has everything to do with pre-construction, from choice of materials to making sure things go smoothly from both a budget and site complications perspective. Engineering opens doors to deeper understanding of a project, not just the calculus to get it done, to ensure timely project delivery.

Enjoying Outdoor Spaces

As much impact as good engineering can have, sometimes the work is about leaving that impact with a minimal footprint. This can not only benefit clients, but members of the community that the project might impact. So much of engineering is about enhancing our open spaces and natural landscapes with low-profile infrastructure that allows for greater access and enjoyment from the populace, which can be as simple as a well-placed jungle gym or as complex as designing administrative facilities for parks and natural attractions.

Bike paths, multi-use paths, all of these are often not thought of as a crucial bit of engineering, however they double down on active transportation of the area while continuing to encourage a healthy lifestyle.

Trails and trailheads play a similar role — allowing people to access and connect with nature while preserving the spaces in which they exist and generating interest in the natural environment while in an effort to preserve it.

The thing I like most about working at Otak is the awesome, interdisciplinary team that I get to work with.

Chris Romeyn – Otak Sr. Water Resources Engineeer

And again, even before construction or the start of a project, feasibility studies in these environments also fall into the wheelhouse of engineering, ensuring the safety, sustainability, and resiliency of the site so people can enjoy it, catching problems in advance that might hinder project completion.

Multiple Engineering Disciplines, One Team

The work of engineers at Otak is multi-faceted and interdisciplinary, and we’re proud that our work goes toward the betterment of the communities we serve. The voices, experience and expertise of the engineering teams within our ranks reflects what their work means to them. Take a closer look at the depth and breadth of project work from one of our most esteemed and recognizable practice areas.

Vancouver Waterfront Gateway

Vancouver Waterfront Gateway is a mixed used development in the city of Vancouver, Washington. The project includes an 8-story mass-timber office, 6-story mixed use market rate apartment building, 6-story affordable apartment building, 7-level free standing parking garage, and extensive open space development between the buildings.

The Missing Link Between Downtown Vancouver and Its Waterfront

Vancouver City Hall and Esther Short Park are immediately to the north and the Burlington Northern rail line borders the south side of the site. On the block west of Esther Street, the development includes an 8-story mass-timber office, 6-story mixed use market rate apartment building, 6-story affordable apartment building, 7-level free standing parking garage, and extensive open space development between the buildings. Development on the block east of Esther Street includes a 6-story mixed use, market rate apartment building. That building features 2-level parking with a retail podium, as well as a large public plaza to the north and ‘makers alley’ along the east side. The total project building area is roughly 570,000 square-feet enclosed building area plus 210,000 square-feet of structured parking area, including approximately 375 residential units, 140,000 square-feet of office space and 40,000 square-feet in retail space.

Sustainability In Action: See How One Bridge Engineer Puts a New Spin on Biking to Work

Sustainability is now a top priority for firms across the globe. According to a recent Mckinsey poll, a larger share of executives now say that sustainability programs make a positive contribution to their companies’ value both in the short and long term. 

Greater still, over a third of global consumers are now willing to pay more for sustainability-integrated services and products. Now more than ever, individuals are both looking for more environmentally sensitive alternatives and looking to firms to champion resilient initiatives. 

“When you’re going and inspecting pedestrian bridges, being a pedestrian just feels right.”

David Graff – Otak Bridge Engineer

Given the information, the time has never been better for people and firms to truly live their sustainable values—not only to internal stakeholders but also to external partners and communities.  

Otak is excited to highlight a Bridge Project Engineer in Colorado who is truly living those values especially on the jobsite. 

We would like to introduce you to David Graff, who biked 22.7 miles over three days through the City of Aurora for a single project—both to reduce his carbon footprint and get a leg up on his competitors in the art of pedestrian bridge inspection. 

A Sustainable Approach to Pedestrian Bridge Inspection

Who is David? 

David Graff, P.E. is a leading voice in our firm for bridge engineering in the Rocky Mountain West. Serving as project manager for bridge inspections and replacements throughout the region, his career is one of excellence at the highest standard. As a member of our structural engineering practice, David is also a certified bridge inspector for the National Highway Institute (NHI).  

He also happens to be one of Otak’s best cyclists, and calls the back roads and pedestrian areas of Colorado his backyard. A bike commuter and environmentalist through and through, David had long awaited a chance to merge his love of cycling and the love of his work—what he calls “Two of my favorite things.” It took one RFP dropping from the City of Aurora to give David that chance. 

What’s the Project? 

The City of Aurora PROS 2022 Bridge Inspections project is one uniquely fit for David and his talents. In addition to being a certified NHI bridge inspector, David has also been running inspections on pedestrian bridges for years in other cities like Vail and Aspen—a niche market in the Colorado region. He specializes in full scale inspection, or the art of inspecting every bridge within a given municipality for deficiencies, structural soundness, and overall ability to serve the community where the bridge lies. 

The problem in Aurora? A notable pedestrian bridge suffering from erosion and a washed away backfill underneath the approach lapse. David and his team were able to win an initial contract for the bridge in question, and later sold the city on inspections and service for every pedestrian bridge in Aurora.  

Thanks to perseverance and long-standing relationships in Colorado, David was tapped to lead this charge behind this renewed effort to fortify and inspect pedestrian bridges across the community.

Why Bike to Each Site? 

In David’s own words, “When you’re going and inspecting pedestrian bridges, being a pedestrian just feels right.” To truly experience the bridges in their full capacity, David felt that he needed to “be a pedestrian” to do his best work. Besides making the work more enjoyable, he also found that riding his bike would be more efficient from both a time and sustainability standpoint. 

Parking is limited in many of these spaces where pedestrian bridges exist, like the ones on the Highline Canal Trail and Sand Creek Park. Armed with just a bike, David was able to saddle right up to each bridge and perform a full inspection as an active user. Saving time walking between a car and the site, while also saving emissions by biking seemed immediately like a no brainer. 

What Did David Find? 

There are three categories of deficiencies that every bridge inspector looks out for on a trip to a site: 

  • Maintenance – Basic upkeep. Things like trimming trees that are growing underneath bridge, clean debris.
  • Preventative – Things that aren’t problems yet, but if not addressed could become a problem. 
  • Repair – Deficiencies that could threaten structural integrity or safety of bridge. Should be address before next inspection or immediately. 

While he’s only a third of the way through the full-scale inspection cycle, those he’s visited look to be in good shape out of the 26 he’s biked to this year. 

More Than Just Bridge Inspectors 

Of course, pedestrian bridges differ from vehicular bridges.  

Vehicular bridges tend to be bigger and have traffic moving faster making deficiencies more difficult to notice in passing and potentially more hazardous. And when it comes to pedestrian bridges, there also isn’t a governing body that ensures certain standards are met, which can lead to the maintenance of pedestrian bridges being more likely to fall by the wayside. Still, in either case, it’s ultimately the same expertise and principles come into play for inspection. 

David stresses here that himself and his team are not just bridge inspectors—they’re bridge engineers, meaning that they’re capable of giving reasons why deficiencies arise and structural fixes for problems, which ultimately saves money for clients as issues are caught early on.

Villebois Subdivision

An expansive 480-acres in Wilsonville, Oregon provides the spectacular site for the Villebois subdivision development. The design brings the area’s residential neighborhoods into a cohesive environment of forests, open spaces, ponds walking trails, and magnificent vistas.

Creating a Cohesive Environment of Outdoor Spaces and Residential Neighborhoods

The project was completed while working in close coordination with the master planner and the City of Wilsonville to create street and site network that encompasses 135-acres of single-family residences and open spaces while preserving the natural features of the site. Within the scope of the overall project were residential subdivision developments, engineering of public roads and private alleys, utility infrastructure design, water quality and detention ponds, and enhancement and creation of wetlands. Final design elements include greenways, trails, neighborhood and regional parks, a future community swim center, and entry monuments.

Center Commons

A catalyst for revitalized neighborhood livability, Center Commons is an urban mixed-use development of seven buildings that combine residential with retail and intimate private spaces with shared areas. Highlighted by a plaza that is part street, part pedestrian mall, and part park, the project is regarded by TriMet, Portland Development Commission, and the neighborhood as a model for transit-oriented, in-fill development.

A Model for Transit-Oriented, In-Fill Development to Revitalize a Neighborhood

Featuring preserved landmark vegetation, high-density and energy-efficient housing, the city of Portland’s goal for controlling urban sprawl while preserving green spaces is integral to the Center Commons design. With an emphasis on developing the community through accessibility, the project incorporates walkway shortcuts from public spaces to adjacent light rail and bus lines to strengthen the relationship between housing and transit. The Otak team met several times with the Center Neighborhood Association where many issues were addressed with the community to optimize project elements including the overall design parking, density, and amenities.

Oregon Dental Service: Milwaukie Plaza

With the goal of sustainably expanding their offices, Oregon Dental Service (ODS) set their sights on a 50,000 square-foot industrial facility within the Willamette River Greenway. The Otak project in Milwaukie, Oregon focuses on the adaptive reuse of the poured-in-place concrete structure – while developing the 7.55 acres of land it’s built on – to create a modern cooperate office environment.

Industrial Reuse for a Sustainable Office Environment and Community Landmark

The building – originally constructed in 1956 as an industrial facility – is surrounded by residential development and, in its prior form, presented a stark image highly visible from major arterial access. The new design softened the original structure with the use of transparent additions to the building, improving the ascetics and natural lighting in the process. Design for the ODS Milwaukie Plaza allows views into the interior, as well as light, to break down the looming mass of the building. Creation of an interior street with light wells punched into the building contributed to natural lighting as part of a modern office layout. The application of these architectural devices creates the corporate image that ODS sought while creating a more appealing visual landmark for the surrounding residential community. Daylighting, sustainably-harvested hardwood floors, and the reuse of an old factory led to this project’s recognition for several awards, including acceptance into the US Green Building Council’s LEED – Existing Building pilot project.

The Yards at Union Station

What began as an underutilized quasi-industrial site in Portland’s Pearl District neighborhood was transformed into a nationally-recognized example of successful urban redevelopment. The Yards at Union Station would mark the district’s first housing project, and it set the tone for subsequent redevelopment in the area. An existing development of four and five-story buildings would grow to include turning 7.5 acres of decommissioned rail yards into a vibrant addition to the newly minted residential community with an emphasis on affordable housing, altogether offering a total of 724 rental and for-sale units for tenants of varying income ranges.

Brownfield Site Development to Revitalize Portland’s Historic Union Station Railyards

Constructed in 1896, Portland Union Station is an established landmark for the city that’s easily recognizable for both it’s Romanesque and Queen Anne architecture as well as its 150-foot clock tower. Sitting adjacent to the Yards at Union Station project site, terra cotta and molded brick of the Union Station building – which was added to the National Register of Historic Places in 1975 – provides the basis for a cohesive motif in the neighborhood. Use of the rail yards contaminated the soil meaning The Yards at Union Station would be developed on a brownfield site. The opportunity to clean up the site for redevelopment allows for the space to be safely reinvested in the community. This sustainable design also includes stormwater planters, energy-efficient lighting and native plantings among other features. With a priority on equity the city of Portland emphasizes that its investment make sure projects address the community’s greatest unmet community needs not only in housing but in economic equity. With over 200 jobs created, this project also exceeds the City’s MWESB goals for diversity in contracting on its way to becoming a viable residential neighborhood in the heart of the city.
