Marsh Creek Road Bridge

Marsh Creek Road Bridge

Marsh Creek Road Bridge is located in the unincorporated area of east Contra Costa County between Clayton and Brentwood.  This $4.9 million project replaced an existing 29.5 ft. wide by 44.5 ft. long steel girder bridge with a new, wider, two‐stage precast/pre‐stressed wide‐flange California Bulb Tee girder bridge. Additionally, each bridge abutment had either wingwall or retaining walls constructed in each corner of the bridge.

The new bridge has two 12 ft. lanes and two 8 ft. shoulders. Furthermore, several Accelerated Bridge Construction (ABC) techniques were used in an area which had environmental restrictions. In addition, the project area had 6,000 vehicles/day traveling along Marsh Creek Road. Construction was staged in four phases.

This project was primarily funded by Federal Highway Bridge Replacement funding, Local Road funds, and SB‐1 funds. Moreover, the project was designed to Caltrans standards.

This project used high early strength concrete. In addition, concrete accelerants, and soil‐cement backfill with geogrid were used. This project further called for 22 ft temporary soil‐nail shoring walls along with a Soldier pile wall with concrete facing. Further, the project team approved two special concrete mix designs, one with higher cement content and water reducers (Delvo). The second with concrete accelerant BASF MasterSet AC 534, which was pre‐approved through Caltrans. This helped achieve over 4,200 psi concrete in 3 days.

BSK Associates

BSK acted as a subconsultant to Substrate, Inc., and under Hill International’s direction. Moreover, BSK’s role in the project was to support source inspection of six – 88’ 3” long girders at Confab LLC in Lathrop. Additionally we provided Quality Assurance materials testing/special inspection of structural backfill, and aggregate base; as well as, hot mix asphalt and structural concrete construction elements.

This project was an awardee of the American Public Works Association for Project of the Year in 2018. BSK Associates is proud to have been a part of such an amazing project!

Peterson Road Improvement Project

Peterson Road Improvement Project

peterson-road-improvement-project

The Peterson Road Improvement Project was located in Auberry, Fresno County, Ca. Following the 2020 Creek Fire, damage to the southwestern slopes adjacent to Peterson Road east of Tollhouse Road were sustained.  Furthermore, it is understood the slope had exhibited minor sloughing in the past. However, after recent fires and increased truck traffic, slopes had exhibited more significant movement.  Curbs along the road edge had moved several inches. Additionally, in three locations radial cracking patterns emanating from the slope edge were visible in the asphalt pavement. The slopes below the roadway were approximately 20 to 40 feet high.  Moreover, previous drainage along the roadway appeared to include diverting water to the shoulders and use of culverts. New retaining walls were designed and planned to be supported on shallow foundations or micro-piles.

Repair of the landslides at the site was under a tight schedule to improve the road before the community could start rebuilding following the Creek Fire. Performing geotechnical investigation, laboratory testing, and preparing the report was completed within 10 business days. BSK is proud to have worked on this project.

First Triathlon Experience

First Triathlon Experience

First Triathlon Experience By: BSK Associates, South Valley Regional Manager, On Man Lau, PE, GE.

First Triathlon Experience written by BSK, South Valley Regional Manager, On Man Lau, PE, GE. featuring Malibu Triathlon experience.

 

Conquering the Triathlon Fear

This past September 26th, 2021, I had my first triathlon experience in Malibu, CA. The race included 0.5 mile of open water swimming in the Ocean, 17 miles of cycling, and 4 miles of running. The idea of entering a triathlon has always been on my bucket list. However, I am not a strong swimmer, and had never swam in open water. As with many of my excursions, this experience was the result of a challenge from my brother.

Once I decided to enter, I knew I had to focus my training on my weakest element. My goal is to overcome my fear of swimming, and build my endurance for the other portions of the race. In order to accomplish swimming a half mile distance in open water, I needed to focus on proper technique. I was lucky to connect with several experienced swimmers at the gym, and they all gave me valuable pointers and feedback. Even though I was only able to swim a couple of laps at the time, the swimmers I met during my daily training encouraged and energized me to push through and persist. In addition, YouTube also provided me with valuable tips from professional triathletes and swimming enthusiasts. Within three months, I was able to complete thirty laps at the gym without stopping!

Gradually, I began to believe that I could complete the triathlon. This race was an opportunity to face my lifelong fear of water, and for the first time, I felt confident that I could overcome!

The Triathlon Experience

On the long awaited day of the triathlon, the excitement and overall exuberant energy at the event was palpable. The thrill and anticipation of it all was made more meaningful by the attendance of all the families and supporters of the participants. There seemed to be endless poster signs from loved ones. I would soon realize how important these shows of affections were, as I would look for, and locate my family throughout the race.

The first leg of the triathlon requires the athletes to swim past the waves before moving on to the half mile required distance. It was definitely discouraging to see many young athletic swimmers struggling to get through the waves before our turn to start. As luck would have it, just prior to my group’s start to go into the water, the DJ played the theme song from Rocky, as I had requested earlier. The lively music was just what I needed to propel myself into the task at hand.

The Triathlon Struggle

As I fought with the waves to begin swimming, the reality of the open water was a shock to my system. Due to my inexperience, I inadvertently swallowed excessive amounts of salt water, and the view of the vast ocean was overwhelming. As I began to panic, a nearby lifeguard, Joe, came to my rescue. While I took respite on his floater, Joe offered some reassurance, “On Man, you still have a long way to swim…there’s no shame in quitting this part of the race…”.

My mind absorbed Joe’s advice. for a split second, I contemplated quitting while starring at the distance still to swim. However, I envisioned the looks of support and pride in my family’s eyes as they waited with excitement for me. Just as I can always count on their support in everything I do, I knew without a doubt that they have confidence in my ability to overcome my fears and conquer the quest that awaits me.

The Triathlon Reward

In an instant, I was able to renew my determination, and pushed forward to continue on. Just as the experts predicted, swimming proved to be the most difficult portion of the triathlon. Once completed, the burst of endorphins enabled me to maintain a study pace during the cycling and running components. Each time I caught a glimpse of my cheering family throughout the race, the love I felt from them provided wind on my back to carry me through.

What did I learn from participating my first triathlon experience at the 2021 Malibu Triathlon?

I learned the importance of consistent training to prepare for physical challenges. On the other hand, mental challenges are harder to overcome. For me, the defining factor to prevail over my mental obstacles were the support of my family. This experience has provided me the life lessons of importance of unconditional love and support. It has also taught me to be courageous to face our fears for the benefit of personal growth.

What Are PFAS?

PFAS are man-made chemicals that include Perfluorooctanoic acid (PFOA), Perfluorooctanesulfonic acid (PFOS), GenX, and several additional chemicals. In fact, PFAS are made up of more than 3,000 man-made chemicals that are largely unregulated.

The U.S. began manufacturing these chemicals during the 1940’s. In 2006, the EPA launched the PFOA Stewardship Program which eliminated the use of several PFAS chemicals. Unfortunately, the U.S. still receives these PFAS compounds from imported goods from around the world.

PFAS are a concern because they do not break down and therefore bio accumulate over time. Furthermore, food, household products, animals, drinking water, and humans have all tested positive for PFAS. In fact, research has indicated that most people have detectable amounts of PFAS in their blood. Additionally, it is believed that everyone, even those who have not consumed drinking water that has been contaminated, will have some exposure to PFAS during their lifetime.

PFAS exposure can lead to many adverse health effects in humans including (but not limited to) thyroid hormone disruption, liver and kidney toxicity,  reproductive system and developmental damage, low infant birth weights, harmful effects on the immune system, and several different forms of cancer.
