I did my undergraduate degree at UC Berkeley and am now in my second year at Stanford pursuing my master’s.

How did you find out about Degenkolb?
I found out about Degenkolb from word of mouth from people at Stanford.

What have you been working on this summer?
This summer I did ATC work where I designed a concrete moment frame building according to the 1994 UBC. The goal of this project is to then evaluate this design to current standards to inform us how older buildings should be retrofitted. I also worked on building Revit tools using the Py Revit API as well as some forensic work.

What memory stands out to you from your internship?
The most impactful memory from my time here was completing my ATC project which took me eight weeks to complete.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
I would recommend being vocal about your goals and seeking and meeting the people that are doing the work which you want to do in the future.

Describe your ideal day off.
My ideal day off starts with getting up relatively early say 9am. I would then head to the gym and get a good workout and shower in there, before heading to a lovely breakfast spot and enjoy a quality meal with a nice coffee. I would then take a book to a park with some friends and either just hangout; play some games; or read. Following this would be dinner with friends followed by a fun night out.

What school are you attending?
I attended UC Davis for undergrad and I’m currently a graduate student at Stanford University. I’m heading into my second year in the fall and plan to complete my master’s degree by the spring!

How did you find out about Degenkolb?
One of my classmates at Stanford was an intern last year and he spoke well of his experience. I also had a chance to meet a few engineers from Degenkolb at my school’s career fair last fall.

What have you been working on this summer?
I designed equipment anchorage for a confidential client in the science & tech industry. I’m working on a research project that involves designing a concrete moment frame building according to different codes to see how codes have changed over time. I’ve also had the chance to develop tools for Revit using Python.

What memory stands out to you from your internship?
The difference between school and the industry has been eye-opening. I get to apply what I’ve learned from school on a real project while also gaining more practical skills that I could only get in the industry. Overall, I feel like my conceptual knowledge has been solidified through my time at Degenkolb.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
If you have a specific interest that you want to explore, reach out to the people involved! For example, I’m interested in programming, so I let my manager know and I was invited to work on a programming project. Also, the social events are a great way to get to know your coworkers and make connections.

Describe your ideal day off.
My ideal day off starts with getting up relatively early say 9am. I would then head to the gym and get a good workout and shower in there, before heading to a lovely breakfast spot and enjoy a quality meal with a nice coffee. I would then take a book to a park with some friends and either just hangout; play some games; or read. Following this would be dinner with friends followed by a fun night out.

Good food and exploring a new place with someone I love.

What school are you attending?
I attended UC Davis for my undergraduate degree (just graduated!) and I’ll be attending Cal Poly for my master’s degree after my internship ends.

How did you find out about Degenkolb?
I found out about Degenkolb through my Steel Design professor at UC Davis who was asked by a Degenkolb engineer to share information about a summer internship opportunity with his students. It just so happened that this Degenkolb engineer was a former UC Davis PhD student (now graduated) who taught my Structural Analysis class!

What have you been working on this summer?
This summer, I’ve been able to see a wide range of projects. I started off the summer visiting reconstruction sites and designing temporary construction shoring for one RCN project. Then, I was able to get into the structural modeling side of things, using software like RAM, ETABS, and EnerCalc—none of which I had seen before—for projects ranging from early-stage planning for a community center, to vibration analysis for mass-timber structures, to footing design for a hospital building.

What memory stands out to you from your internship?
Beyond learning a lot about structural engineering practice itself, I think some of the most meaningful memories I’ve made while at Degenkolb are from my interactions with the rest of the office. Chatting (or just listening) to the staff around the office or at lunch and joining social outings with them after work, like painting pottery with the Women’s Group, helped me get to know everyone a little better and feel like a part of the team in Oakland.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
Though this will probably make me sound like a broken record, asking questions is the most important thing you can do to make your time at Degenkolb valuable to yourself and those you work with. Asking questions may not come naturally to everyone (it certainly doesn’t with me), but I’ve always felt encouraged to ask questions and ask them sooner rather than later. If you’re just finishing your undergraduate degree, you might be feeling entirely out of your depth. That’s something that people at Degenkolb understand, and everyone I’ve worked with has been so helpful at explaining concepts or projects to me that I hadn’t seen before or guiding me toward resources to learn about them on my own.

Describe your ideal day off.
My ideal day off would probably consist of attending another Taylor Swift concert with friends, but while that’s not possible, I enjoy playing The Legend of Zelda and spending time with my cat Louie at home!

What school are you attending?
I graduated Cal Poly, San Luis Obispo this past spring quarter with a degree in Civil Engineering and will be attending UC San Diego to pursue my Masters in Structural Engineering in the fall.

How did you find out about Degenkolb?
Degenkolb did a presentation about mass timber structures in one of my undergrad design classes. Afterwards, I was very interested in getting involved with the company’s diverse and complex projects.

What have you been working on this summer?
I’ve worked on a structural non-performance component study for a local hospital, performed equipment anchorage calculations for a new hospital construction, and I’ve also created an ETABS seismic evaluation model of a six-story reinforced masonry hotel structure.

What memory stands out to you from your internship?
I had the opportunity to conduct one of Degenkolb’s first hospital survey walks using a new lidar scanner that maps out equipment noncompliance areas of the building. While I did have the great privilege of waking up at 4am to do this survey, I also got to interact with many of the patrons and essential workers onsite who were curious as to what our team was doing. I took pride in knowing that the work I do contributes to ensuring the safety of every patient and hospital worker affiliated with that hospital.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
I would recommend that every Degenkolb intern be prepared to ask a lot of questions. Ask any question that pops into your head, be it big or small, because chances are your co-workers will give you an answer and then some! Everyone in the office, from designer to principal, is very approachable and will go out of their way to help you out with any questions you have! The feedback I received helped me learn more about structural engineering than I could have on my own, so definitely stay curious and ask questions throughout your internship!

Describe your ideal day off.
My ideal day off would start with a morning hike on one of San Diego’s many open space trails, followed by some authentic fish tacos for lunch, then a necessary afternoon nap, and an evening Padres game to wrap it up!

What school are you attending?
I completed my bachelor’s degree at the California State University, Sacramento and now planning on pursuing my master’s degree there.

How did you find out about Degenkolb?
I heard about Degenkolb at Sac State University during a career fair.

What have you been working on this summer?
I have worked on RCN/IEG, the reconstruction and investigative engineering projects as well as NPC, the nonstructural seismic bracing design. My work included several site visits as part of the forensics and healthcare areas of work.

What memory stands out to you from your internship?
My most impactful memory was a site visit I did to Lake Tahoe as part of the IEG, investigative engineering project. I felt like a detective on this site visit while enjoying beautiful views.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
I would advise to get involved with different projects to get a feel for various fields of work. This will give you a complete picture of a possible career path at Degenkolb. Also simply enjoy your stay and have fun while learning!

Describe your ideal day off.
I enjoy hiking and nature. My ideal day off would be to go on a hike and explore nature especially somewhere in the mountains during winter.

What school are you attending?
I just completed undergrad at the University of Washington. I will be returning to UW for a master’s degree this fall.

How did you find out about Degenkolb?
I found out about Degenkolb through the UW engineering career fair where I enjoyed talking to Clare Terpstra and Brett Cates. Clare came back to the university for an information session during the graduate school perspective student visit day, and I got to hear more about the work and culture at Degenkolb.

What have you been working on this summer?
I’ve been thrilled to work on a wide variety of projects. I had the opportunity to work on two different hospital projects including designing penthouse structures and windscreens and helping model a first-floor slab. I’ve also contributed to several smaller forensic and construction engineering projects, and a large ongoing non-structural seismic assessment. It’s been fantastic working with so many excellent professionals.

What memory stands out to you from your internship?
Adding the first things I designed to plan sets. I have worked in construction, and being on the other side of the process was exactly why I decided to go back to school and become an engineer. It was really exciting, and I felt like my decision to change career paths was validated.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
Ask lots of questions. Every time I asked one question, I felt like I got my answer plus two bits of bonus knowledge. Ask different people. While it’s great to have a go-to mentor, it’s also worthwhile to meet different engineers and gather different perspectives. No one ever seems too busy to help the intern.

Describe your ideal day off.
My ideal day off is waking up very early and going backcountry skiing in the North Cascades, hopefully watching the sun rise in the mountains then skiing all day. A second day off to sleep in afterwards is helpful.

What school are you attending?
I’m starting my first year as a grad student at UC San Diego.

How did you find out about Degenkolb?
I heard about Degenkolb from other students and professors at UCSD.

What have you been working on this summer?
I have mostly been working on FEA modeling of a prototype shear wall side plate connection that would result in a thinner wall with lighter reinforcement.

What memory stands out to you from your internship?
Getting to meet and spend time with colleagues through the social events.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
Make sure to ask questions whenever you don’t understand something.

Describe your ideal day off.
My ideal day off includes spending time with my family, eating my mom’s home cooking, and reading a book or watching a movie.

What school are you attending?
I just completed my undergraduate degree from UC San Diego and will be returning there for my master’s degree after the internship.

How did you find out about Degenkolb?
I first heard of Degenkolb through the EERI SDC as I was competing for my school’s team for 2 years and Degenkolb has always been the sponsor for the competition. That left me with a good impression about the company. Later, I got to talk with the representatives at an engineering career fair and listen to great experiences my colleagues have had working at Degenkolb. That made me really want to be a part of Degenkolb. And I am certainly glad I got this opportunity!

What have you been working on this summer?
I have been working on a concept study on lateral force resisting systems for a new hospital building. The focus of my study is to design and analyze the implementation of special moment frame (SMF), buckling restrained braced frame (BRBF), and cross-laminated timber (CLT) on the building. I also worked on smaller projects such as some detailing for UCI medical buildings, PIN 75, and UCSB SAP program.

What memory stands out to you from your internship?
The social events like the picnic for the LA and OC offices, and after work dinner/happy hours have really strengthened the bonds between everyone in my office and me. Another cool memory for me is the UCI Topping Ceremony. Not only that I have a great site visit, but it was also a valuable experience to see all the hard work that went into it.

If you could give future interns any advice on how to get the most out of their internship, what would it be?
Be curious, don’t be afraid to take on more challenging opportunities, and make friends/talk to people. There will be tons of new things to learn and the people you know are your greatest resources. The people are the ones that make your experience much more enjoyable.

Describe your ideal day off.
It would be a day where I can spend time by myself or with my friends to relax and do some fun activities like hiking, exploring new food places, enjoying nature, etc. Then I would come home to a delicious homecooked meal with my family and play some games or watch a movie with them.

What school are you attending?
I’m currently pursuing my PhD in structural engineering at the University of California, San Diego, and I’m excited to be entering my third year of studies.

Degenkolb Dispatches Two Earthquake Reconnaissance Teams to Turkey

Degenkolb Engineers assembled two reconnaissance teams to survey the damage of the recent Turkey-Syria earthquake and its subsequent seismic events. On February 6, 2023, a 7.8-magnitude earthquake struck southern and central Turkey and the northern and western parts of Syria. The surrounding region sustained widespread damage and significant loss of life. Our engineers embarked on these trips to search for clues around why certain structures succumbed to ground motion versus others and to help advance the field’s knowledge of structural performance.

David Sommer—an Associate Principal in Seattle—led Team 1 who landed in Turkey on February 27^th.  Other team members included Jose Flores Ruiz (Associate Principal, Mexico), Jerry Luong (Design Engineer, Orange County), Kim Bocanegra (Designer, Sacramento), and Rafael Alaluf—Founder of EQRM International and former Degenkolb engineer based in Turkey.

Jen Gross—an Associate Principal in Oakland— led Team 2 who arrived in Turkey a week later on March 6^th. Other members included Adam Hugo-Holman (Principal, San Francisco), Justin Tan (Project Engineer, Los Angeles), Anthony Ambrosio-Meir (Project Engineer, San Francisco), Rafael Alaluf from Team 1, and Baris Lostuvali—a Project Executive with The Boldt Company and Turkish national. Team 2 convened with Team 1 upon arrival.

During the trip, the teams were in close communication with the Earthquake Engineering Research Institute and shared data via EERI Clearinghouse. Additionally, each team collaborated with non-profit organization, Build Change, to assess ways to support the local disaster relief and recovery efforts.

Both teams’ findings will be published throughout this week at https://degenkolb.com/ideas/

We are happy to share our findings with you. If you’re interested in having our engineers give a presentation about their conclusions, please contact Laurie Lumish at llumish@degenkolb.com.

Waters in the storm…into the house they’re borne

Chapter 1:  Waters from the Storm

The first sign of trouble at the condominium building appeared in late October 2021. Residents in the third and fourth floor units noticed water leaking from their living room ceilings. More leaks appeared in the common areas below a fifth-floor balcony.

The condo building was relatively new, finished in 2018, and there had been no reports of previous leaks into the building. The property manager had a contractor come out to investigate and repair the damage. As the contractor began to remove damaged finishes, more moisture was discovered in the walls and ceilings. Repairs were made, but several months later, in December, more leaks appeared.

A few miles away at a large single-family home, a family of four had recently returned from an extended trip out of the country. It was just before Christmas and, during a storm, the family noticed water dripping from the ceilings in the living room and kitchen. Additional leaks would be discovered in the guest room, recreation room, and garage. The family reported no prior leaks in the home. The custom two-story home was built in 1982 and had stone walls, Mediterranean-inspired architectural elements, arched windows, curved ceilings, hardwood floors, and decorative paintings over Venetian plaster walls.

Across the Bay in an iconic three-story Victorian home, the homeowners noticed a sudden water leak in their garage after a storm in late December. The water flowed openly across their garage floor and out towards the street. When a reconstruction contractor came to the home to repair it, extensive rot damage was found behind the finished walls and ceiling.  It was clear that water had been getting into the walls for a long time, but had only recently leaked into the garage.

Chapter 2:  A Closer Look

Water leaks had appeared at all three properties around the same time—during the rainstorms that blew through the Bay Area in late 2021. But each home was so different—the first, a relatively new condo building; the second, a large 40-year-old home in a suburban setting; the third, an historic Victorian home built in 1900. All three homes had damages that required extensive repairs.

The question to be answered: Were the two big storms in October and December the cause of damage to all three properties? Or were there pre-existing conditions that the storms suddenly exposed? Degenkolb was hired to find out, and sent out forensic engineer Steve Moore.

At the condo building, repairs were already underway after the storms. The contractor had removed some of the wall finishes, covered up the fifth-floor balcony with temporary plastic tarps, and sealed open exterior joints with caulk and backer rod. There were no obvious openings where the water could have entered, but the leaks continued during subsequent storms. Inside the walls, Degenkolb’s Steve Moore probed the stained wall framing where he found solid and firm wood and lightly rusted fasteners with no evidence of long-term moisture exposure. With the plastic installed over the balcony and all exterior joints sealed, how did water continue to leak into the units below?

Down the road at the large single-family home, the evidence told a different story. French doors in the bedrooms and playrooms open to balconies and walkways on the second floor. Floor drains were supposed to have captured rainwater before it entered the residence. We noticed, however, that the wood at the threshold of each door was warped, separated, and split. We also noticed that the floor drains were filled with leaves and other debris. Plants had started to grow up through the drain covers, effectively blocking them. But did this translate to water in the living room ceiling? If so, how?

Across the Bay at the 120-year-old Victorian home, the challenge was following the evidence of water damage to its source. Inside the garage, behind the removed wall finishes, the damage was evident— stained and rotted framing members in the corner around a rainwater drainage pipe. We followed the damage to a second-floor balcony above the garage. Upon examining the balcony floor above, we noticed intact conditions with no obvious voids or cracks in the floor tile around the roof drainpipe. How was the water getting through the balcony floor?

At each residence, it initially seemed the storms were responsible for the damage, since there hadn’t been leaks before or significant rainfall due to the ongoing California drought. But by peeling back the layers and examining the evidence, a few clues were revealed that pointed to other reasons.

Chapter 3:  The Culprits

The exterior wall finishes on the condominium are comprised of stucco, which is designed to allow rainwater to penetrate through the cement plaster and then drain out the bottom. On a balcony, the bottom of the stucco drains onto flashing at the wall-to-balcony intersection. The flashing directs water to a drain system in the balcony floor assembly. The cause of the water intrusion was missing or improperly installed flashing at the wall-to-balcony intersection, likely the result of an original construction defect. The condition hadn’t been noticed earlier because not enough rain had fallen since the condo had been built to become a problem.

At the large single-family home, we determined that when it rained sufficiently, water from the balcony overwhelmed the blocked drain, pooled on the balcony, and then overflowed the thresholds into the floor assemblies. We observed that the wood at the door thresholds was warped and there were deep cracks in the grain. When wood is damaged by water, the cycle of wetting and drying become exacerbated each time. Cracks in the wood become deeper, the cellulose breaks down, and it becomes easier for water to penetrate the next time it rains, causing further damage. It was clear that the wood had become wetted and dried several times before the storms in late 2021. The cause of the water intrusion was a lack of maintenance of the exterior drainage, which resulted in significant water penetration during the large storms of 2021.

At the Victorian, it was clear that the moisture damage to the framing had been occurring for many years, but the water had not previously flowed into the garage. Upon closer examination of the balcony, we identified a failed joint at the guardrail intersection with the exterior wall. The failed joint was the result of dried and cracked sealants and paint, which allowed rainwater to penetrate the wall cavity. The failed joint had been allowing water intrusion for many years, but it was not until the excessive flow in December 2021 that the long-term deterioration was revealed.

Falling rain enters the balcony area and is able to penetrate under the drain due to incorrect lapping of waterproofing materials between the substrates. From there, it travels through the interstitials space in the floor before dripping down through the ceiling and into the condo below.

Rainwater accumulates on the surface of weathered wood, then soaks into the pre-existing splits and gapped joints. Via wicking and capillary action, the water then travels through the splits and gapped joints to the interior of the home, bypassing exterior weatherproofing systems. Standing water from clogged balcony drains contributes to the deteriorated condition of the wood.

Rain penetrates behind siding via cracked paint and deteriorated weatherproofing materials. Once behind the siding, it can migrate down through the wall cavities, causing damage to framing, insulation, and finishes.

Epilogue

Each building had first noticed water intrusion during significant storm events in late 2021. Without any history of prior leaks, it was initially believed that the storms had caused the leaks. But after careful forensic assessments of each location, the physical evidence revealed the actual causes: different pre-existing issues that had manifested well before the rains fell—an initial defect in construction, a lack of routine maintenance, and dried and cracked sealants and paints, respectively. These three examples of sudden rainwater intrusion illustrate the importance of taking the time to closely examine and follow the evidence path and to not just blame the damage on the water in the storm.

____________________________________________________

Dominique Hayet, San Diego

Where do you go to school and what year are you in?
I just completed my undergrad at UC San Diego and will be starting at UC Berkeley for my master’s degree in the fall.

How did you find out about Degenkolb?
Outside of seeing the name at our school’s career fair, I was put in touch with the company by a close professor at UCSD who wanted to help me out in my internship search. Could not have been more grateful for how things turned out!

What is your most vivid memory of your time so far at Degenkolb?
The happy hours are hard to beat! Getting to assist in the design of a parking canopy was a very cool experience, and the Wellness Challenge team walk through downtown San Diego’s first day of Comic-Con was also a great time. And I will not forget coming into the office on my first day in-person to be greeted by a beautiful view of the Coronado Bay Bridge.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
Realize going in that you will be challenged and use that to push yourself forward and seek out help from others. There are plenty new things to learn in the office that school may not fully prepare you for, and the internship program provides an excellent opportunity for exposure and growth in this environment. You may take longer to figure things out than you expect and that is okay, but don’t try doing it all on your own. The office is full of insightful engineers and reaching out for help will always provide you with a new opportunity to learn. Take notes when you need to and get a good night’s rest to make it through the day! And although the work is serious – give yourself time for interacting and getting to know your coworkers.

Describe your ideal day off.
Depending on the season, a drive with friends either to the beach or the mountains. Soak up the sun, grab some dinner and ice cream (or Julian apple pie), and come back home to chill with music, games, and/or a movie or a nice long sleep followed by a morning workout and just relaxing at home.

Judy Guan, San Francisco

Where do you go to school and what year are you in?
I graduated from San Francisco State University with my bachelor’s degree and will be returning in the fall for the 2^nd year of my master’s degree.

How did you find out about Degenkolb?
I found out about Degenkolb through a SEAONC career fair.

What is your most vivid memory of your time so far at Degenkolb?
The most vivid memory so far for me is completing my first Issue for Permit set and having my name on the drawings. It is surreal to think the things I helped design as an intern are going to be built.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
My advice for future interns is to get to know the other engineers in the office and don’t be afraid to ask questions. Everyone is willing to help so do not feel like you need to struggle to figure out the problem on your own. Interns are expected to make mistakes and need help to figure things out. Get the most out of this experience by asking questions whenever something is unclear. This internship is a great opportunity to learn and grow.

Describe your ideal day off.
My ideal day off would be waking up naturally and not to the sound of an alarm. I would take my time cooking food as well as trying out new recipes. Then I would spend my day at home watching TV shows.

I completed my undergraduate degree at the University of Cape Town in South Africa. Currently, I am attending North Carolina State University and will begin my final year of my master’s degree in structural engineer this coming fall.

How did you find out about Degenkolb?
While I was researching internships, I reached out to a friend in the construction industry for networking ties. He mentioned working with Degenkolb on a few projects and was very impressed by the company. I decided to do further research into the matter and luckily came across this opportunity.

What is your most vivid memory of your time so far at Degenkolb?
Aside from the all the social events and the amazing projects I worked on, my most vivid memory must be winning a table tennis game against the highest ranked player in the LA office.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
I would advise future interns to enjoy their time, get involved, be open to learning and lastly don’t be afraid to ask questions.

Describe your ideal day off.
My ideal day would entail a morning round of golf, followed up by an afternoon of watching sports (soccer, rugby or cricket) and finally an evening “braai” with friends and family.

Jimmy Yang, San Francisco

Where do you go to school and what year are you in?
I went to undergrad at the University of British Columbia in Vancouver, Canada. After graduating, I did one year of full-time work as an EIT and decided to pursue further education at Stanford for structural engineering! I will be finishing up my last quarter at Stanford this fall and will graduate December 2022.

How did you find out about Degenkolb?
I first heard about Degenkolb during a “seismic tour” of Stanford Campus and heard Professor Deierlein mention the company’s involvement on campus. Since then, Jim has come to speak to our class in a guest lecturer series. I also had the pleasure of speaking to many current employees at school career fairs.

What is your most vivid memory of your time so far at Degenkolb?
Going on a guided tour with the entire San Francisco office to the Transamerica Pyramid is up there (pun intended) as one of the most memorable experiences I have ever had. The view at the top floor was incredible! I would recommend putting in an escalator to the top floor, even if climbing to the 60^th floor was great for the Wellness Challenge.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
Be vocal about what you want to learn and do. The management at Degenkolb is very open to helping put you on projects that you want to do. Since they aren’t psychics and can’t read your mind, you have to put yourself out there and tell your project managers what kinds of projects and sectors you are interested in working in.

Describe your ideal day off.
I love going out with a small group of friends and exploring places I have never been before. I don’t mind if it’s in the city or in the back country if it’s with the right group of people!

Where do you go to school and what year are you in?
I attend San Francisco State University and am in the final semester of master’s program for Structural/Earthquake ENGR!

How did you find out about Degenkolb?
This internship and company were recommended to me by my academic advisor and my steel design instructor.

What is your most vivid memory of your time so far at Degenkolb?
Designing and building my first (2) 3D models based on structural/architectural plans and ASCE 7-16 chapter 13. This was a very interesting experience because I got to see how influential the different load combinations (especially the drift+gravity combos) are in determining design. It was also a good learning experience to look at a model once it is finally working from the perspective of the contractor and see if each of the chosen members make sense, or whether there is a simpler/more economical solution.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
Spend as much time around all the other engineers as possible, both in and out of the office and ask them questions. Everyone is extremely helpful and willing to share their knowledge and experience in order to give you the best intern experience possible.

Describe your ideal day off.
Playing music and eating good food with friends, going to the beach with my family, cooking a nice dinner for my partner, snowboarding with friends…how can there be only one ideal day off?

My advisor connected me with an alumnus who he had also advised during their undergrad. We met up and had a two-hour long conversation and I determined that from her description of the workplace and what Degenkolb does as a company, that I could be a great fit and vice versa.

What is your most vivid memory of your time so far at Degenkolb?
Every site visit with the forensics team have always been exciting to me, not only because I get to investigate damaged buildings, but because we often meet with the property owners. It really helps to know the face of the people who we are helping and motivates me to put my best self forward to satisfy their needs.

If you could give any future interns advice on how to get the most out of interning with Degenkolb what would it be?
My advice is to not be afraid to ask questions! It is always best to keep in mind that as an intern, I am not expected to know everything, but to be enthusiastic to make connections and learn from my coworkers.

Describe your ideal day off.
My ideal day would be going out for a meal with my loved ones and making arts and crafts together. I love painting, embroidering, and making friendship bracelets!

Please enjoy parts one and two below.

Stanford University’s Lorry I. Lokey Laboratory Studies Chemical Reactions that Provide Solutions to Science’s Biggest Questions

Since 2003, researchers at Stanford University’s Lorry I. Lokey Laboratory for Chemistry and Biological Sciences have sought to find answers to science’s biggest questions by focusing on the smallest of things: molecules, cells, and their chemical compounds. Chemical elements—much like a building’s concrete, steel, or timber—are the building blocks of everything around us. The Lorry I. Lokey Laboratory has united the brightest scientific minds studying these components, witnessing the advancement of knowledge and biochemical investigation for all.

The Lorry I. Lokey Laboratory was built to serve as the most research-intensive structure on the world-renowned Stanford University campus—and it certainly has held up to that vision. Home to research for the Chemistry and Biological Sciences departments, the $42-million, 85,000-square-foot building features state-of-the-art modular laboratories for nine principal investigators as well as 180 students and postdoctoral fellows. Their work in molecular and cell biology and advanced organic synthesis chemistry spans nearly two decades within the laboratory’s walls. Despite much of their research existing on a microscopic level, the scope of their findings is global.

One example is the Wender Group housed on Lokey’s second floor. Studying the intersection of chemistry, biology, medicine, and materials science, the group’s work emphasizes the use of synthesis “to address problems of significance in biology and medicine including eradication of HIV/AIDS, overcoming resistant cancer, and treating cognitive disorders like Alzheimer’s disease (source).” The researchers also focus on the development of new strategies to treat disease as well as new therapeutic strategies to address unsolved medical problems.

Another group is the Burns Lab which explores the “boundaries of modern organic synthesis to enable the more rapid creation of the highest molecular complexity in a predictable and controllable fashion (source).” For the non-chemist, their research seeks to answer a variety of chemical, medicinal, biological, and biophysical questions that can translate to insights, discoveries, and more for human health and the fight against illness and disease.

Chemistry surrounds us: from what we eat and wear to even think and feel. Lokey’s brilliant chemists and biologists continue to research chemical reactions that will give us solutions, benefitting science, human health, and beyond. Degenkolb Engineers was proud to have worked on the design of the laboratory along with architect, DGA.

Reflections on Katrina: Supporting Others in Difficult Times

A pair of children’s shoes hang from a telephone wire. Broken picture frames filled with water-damaged photos of major life events litter the ground. Gemstones that used to hang from a chandelier that had been in the family for four generations glint feebly from underneath piles of debris. Katrina’s storm clouds had dissipated three months earlier, but the devastation remained scattered across the communities and land that had the misfortune of being in her path.

Degenkolb* staff was on-site to conduct an investigation on a homeowner’s claim. This time, the homeowner met the engineers and their Claims Coordinator at the site. Mounds of rubble lay in a heap on top of the slab where his house used to stand. As the engineers did their work, the homeowner sifted through what was left. Much of it was unrecognizable — items damaged during the storm had then sat outside, exposed to sun, humidity, and more rain for weeks and months. Many sentimental items were now beyond salvageable. The homeowner was looking for anything that had even remotely survived.

Lisa Esquivel was the team’s tireless Claims Coordinator. When Degenkolb’s investigative engineering team started getting calls to go down to Mississippi and investigate the cause of loss — a nuanced determination between the wind from the storm or flooding from surge waters — Lisa was the one who found a furnished apartment to stay in.  She and the IT manager were the ones to go out and buy the computers and tech equipment needed to operate a field office (this was well before remote work setups were common). Lisa coordinated the schedules, set up the files, made sure there was food in the fridge, and towels and bedsheets were cleaned between multi-week shifts of engineers. When the engineers went to the sites, she was the one who interacted with the homeowners. She offered a sympathetic ear when they told their stories – what they went through when they left, or the reasons for why they didn’t. She heard the way they agonized in uncertainty when they didn’t know what had happened to their home or whether their insurance carrier would cover their loss.

In the evenings, while the engineers discussed the types of damage they’d seen and the indicators of cause of loss, Lisa thought about what she’d seen, sometimes overwhelmed to tears with empathy for the kind, generous, and welcoming people who’d lost almost everything. These people’s lives — nearly everything they owned — lay scattered across neighborhoods and towns, some of it lost forever. During catastrophes like a hurricane or a wildfire, the advice is that things can be replaced but people cannot; it’s meant to encourage folks to prioritize their safety first and foremost. This saying is certainly true; a human life cannot be replaced. But losing everything around one’s life—photos, children’s’ drawings, gifts from friends and family, hobbies and collections—is still a significant loss that takes an emotional toll.

The home where the team had been that day was once used as a filming location for a major motion picture in the late ‘90s. At that time, the homeowner hadn’t accepted payment for the use of his home for filming. At the end of shooting, the crew presented him with a unique gift: A framed dollar bill signed by the crew and stars of the film, which included several major Hollywood actors. While sifting through the debris, he found the frame with the signed dollar bill intact. Excitedly, he showed it to Lisa, who shared in the man’s joy at finding at least one of his irreplaceable items. It was a small, but impactful, step forward in a long journey to recover and rebuild.

Sixteen years later (to the day), Hurricane Ida struck the Gulf Coast once more. This time the levies held, but the winds and water appear to have been no less devastating in 2021 than they were in 2005. For Ida, the post-catastrophe work hasn’t yet begun—it will be weeks to months before adjusters and engineers are able to safely visit sites and assess damage. That tireless Claims Coordinator, Lisa Esquivel – now the Forensics Operations Manager for Degenkolb Engineers —is reflecting on the valuable lessons we learned from Katrina, preparing herself and her colleagues for the journeys they may take, and hoping for small but impactful steps forward by those who were affected by Ida.

*Degenkolb Engineers acquired Barrish Pelham Consulting Engineers in 2018. Staff involved in the Hurricane Katrina recovery story were at the time employed by Barrish Pelham and are now employees of Degenkolb Engineers.

Facilitating the Design: A Case for Construction Engineering and Structural Engineering Co-Existing

Before a critical building—like a healthcare facility—can open its doors to patients, medical personnel, researchers, and others, a design team is hard at work making sure the ideas can become a reality. A crucial step between design to opening day is construction engineering. Known at Degenkolb Engineers as CE for short, construction engineering facilitates the design of a structure by—sometimes literally—providing the necessary support which brings a design to life. Although CE serves to facilitate the design, its importance to the success of the whole project cannot be overstated. Robert Graff (Principal, San Francisco) knows this reality well. “Every project is different and shaped by the site itself.” Whether it’s accounting for existing adjacent structures, the unique geography of a lot, or every stakeholder involved, CE is there to find a solution.

When building Highland Hospital’s new acute care tower in Oakland, CA, the design team encountered a challenge with the Satellite Building and a significant grade change from one end to the other. In addition, there was an existing building scheduled for demolition that partially retained this very grade change. Degenkolb was providing SEOR services for the new hospital tower as well as bridging documents for the Satellite building, but was also contracted to provide construction engineering services for the entire project. By engaging our CE team early, all involved were able to find an economical, efficient way forward. The solution: a three-story retaining wall—comprised of new shoring wall elements and existing building walls reinforced with new tie back anchors—that separates the Satellite building from the hillside. By employing this method, the building no longer had to serve as the retaining wall, which proved to be more cost-effective, improved the seismic performance of the building itself, and repurposed parts of the existing building to facilitate the new Satellite building. Additionally, this allowed the architects to have the building “be what it wanted to be,” preventing unnecessary architectural sacrifices that could affect the design’s vision.

From left to right: The original hill, the hill after excavation, and Andrew Scott (Principal, San Francisco) in front of the three-story retaining wall while it was under construction.

Highland Hospital also required the demolition of wing buildings to make the new acute care tower. The CE team planned for a selective demolition and shoring of part of the adjacent structures, which facilitated a more streamlined process before the foundations were laid. Thanks to these decisions during the excavation shoring, temporary building support, and historic building monitoring, the 315,000 square foot, nine-story, 169-bed acute care tower came to life with minimal delays.

Stories like these illustrate how costly design decisions requiring resources and effort can instead be spent in the CE world where creative solutions abound. In the case of Highland, the CE and structural design team were one of the same, run by separate project managers but under the same roof at Degenkolb Engineers. Often the design firm hires a subcontractor that then hires another subcontractor engineer to implement the shoring work, introducing them to the project far later in the design process. “The earlier CE can be in the room, the better,” Robert adds. Not only does earlier involvement prevent potential issues down the line—including making things more challenging and costly to build or even triggering a possible re-design—but can allow for ideas on alternative ways forward to bring stakeholders’ vision to life when creating the next world-class facility.

Robert adds that “the level of understanding, communication, and coordination by having it run out of the same office is happening organically rather than being forced.” This integrated approach has many benefits, especially when communication and coordination are key to CE’s success. Although the integrated CE approach is a rarity with facilities of Highland’s size, comparable projects focused on critical facilities can thrive along this path, making every stakeholder and member of the design team satisfied with the result they are delivering to the community.

How I Found Myself Upside Down in A Dumpster

A carrier adjuster contacted Degenkolb because they needed a forensic engineer to determine the cause of a failed fire sprinkler that had flooded an office area in a local commercial building. Just after 11:00 pm on the date of loss, the fire department received a notification that the sprinkler system for the building had been activated. After determining there was no fire, the fire department temporarily shut-off the fire sprinkler system. It was reported that a single fire sprinkler had failed and damaged the office area below it.

When I visited the site, I saw that all the cubicle furniture and carpet flooring had been removed from the roughly 50-foot by 50-foot square room. Additionally, the four acoustic tiles around the failed sprinkler were missing. The building manager told me that the four panels had been found on the ground the morning after the loss and were thrown in a dumpster at the back of the building.

I documented the existing conditions of the room and took a very close look at the failed sprinkler head. The mercury link for the fixture had been replaced and the fire protection system for the building had been reset and was properly functioning. I noted no evidence of distress on the surfaces of the fixture or long-term corrosion on the pipes and/or fittings. The pipe support hardware, the roof framing, and the surrounding building systems appeared intact and properly functioning. So, how did this single fire sprinkler in the middle of a conditioned office area fail? Where was my “smoking gun”?

I decided to check the dumpster at the back of the building. I needed to see the ceiling panels around the failed sprinkler head. I swallowed my pride, reflected on my desire to find the real cause of this loss, and did some dumpster diving, which is ultimately how I ended up upside down inside the dumpster. Thankfully, my efforts paid off! Under plastic sheeting and some carpet rolls, I found three of the four ceiling panels. They were tattered and damaged, but I was able to reassemble them on the ground next to the dumpster. Extending across two of the three panels, adjacent to the location of the fire sprinkler, were a series of black crescent-shaped shallow grooves in the acoustical panel surface. How and when did these Nike swoosh shaped markings get on the ceiling panels?

I returned inside where I met with the manager in his office and asked more questions about the building. Inside his office, the gadget-loving engineer in me immediately noticed a large remote-controlled helicopter sitting on the floor. The manager explained that several employees would fly the helicopter in the parking lot during lunch and, when not in use, it was normally stored in the damaged office area. The helicopter and its controls were found on the floor the morning after the sprinkler failed. I took a closer look at the helicopter and noted a white residue along the leading edges of the rotor blades.

Following this lead, I asked the manager if any employees were in the building when the fire sprinkler failed and he said no; he had been the last to leave the building earlier that evening. I then asked him if there is a cleaning service for the building and immediately his eyes popped wide open—something had clearly clicked for him. The manager accessed the security system for the building and found that around 10:30 pm on the date of loss, someone had accessed the building. The manager contacted the cleaning service company and they admitted that the employees in the office that night had been playing with the helicopter inside the office area when it flew out of their control, impacted the ceiling, and hit the fire sprinkler, which then triggered the fire suppression system.

This investigation shows that forensic engineering is about more than a single discipline; it’s about following clues, interpreting their meaning, and testing hypotheses. Whether the cause is obvious—like a tree has fallen through a roof or a car has gone through a wall—or harder to determine—like what’s causing mold growth inside a window—the first step in determining the cause is collecting evidence and making observations. With a little extra “diving” effort, asking pointed questions, and following the evidence, a forensic engineer can successfully determine the cause and origin of damage, even when it’s unexpected! This was one of those times.
