The BART Berkeley Hills Tunnel runs between the Rockridge and Orinda stations. Construction began in 1965, with construction completed in 1967 after 465 work days. The tunnels are offset to the north of the Caldecott Tunnel, and provide a more direct alignment. The contract for construction was $31 million USD.
Channel Lumber has partnered with engineering and construction firms providing services and goods in BART construction since BART’s inception.
The Berkeley Hills tunnels are 3.1 miles longs and about 17.5 feet in diameter. There are emergency cross tunnels every 1,000 feet for evacuations. The east portal has roll down doors which close off the tunnel, or allow for ventilation in and out. The tunnel runs across the active Hayward Fault.
Construction of the tunnels involved over 27 million pounds of steel. The rate of advance between boring, blasting and excavation was 19 feet per day. The project was one of the earliest high profile tunnels to be built with Tunnel Boring Machines (TBMs) as opposed to hand mining.
The building of BART during a cycle of high inflation, led to many well documented budget and political problems. In many instances these problems led to political reform. In 1974 BART was nominated for Outstanding Civil Engineering Achievement of the American Society of Civil Engineers.

Concrete Forms for Level 10 Sunnyvale projects.
Level 10 is a leading construction company based in Northern California. Channel Lumber has partnered with Level 10 on numerous projects, primarily through concrete forming materials.
Level 10 recently completed several high profile award winning projects including the new Facebook Campus (MPK 20) and 181 Fremont, now the tallest skyscraper on the San Francisco skyline.
Currently, Level 10 is working with the Jay Paul Company on two sites in Sunnyvale, the Moffet Gateway and Moffet Place Campus. These projects are unique in that they are not being built for a specific company. Both of these projects were designed and developed to be put on the market for sale after completion.
The Moffet Gateway, completed in 2016, features two seven story buildings, with a parking structure, roof-top garden and lounge. The Moffet Place Campus is a 1.9 million-sq-ft. Class “A” office campus. The campus will also feature an event center, several parking structures, and other modern amenities. The project has a completion date of April 2020.
In keeping with Channel Lumbers high standards for Green Building, both the Moffet properties are targeted for LEED® Platinum sustainability, the highest level awarded.

Technology is transforming the lumber industry, and Resysta® is at the leading edge. At Channel Lumber we are pleased to distribute and represent this Green building product. Here are some facts about Resysta® that can help you decide if it is right for your next project.
1. Resysta® is made of agricultural waste. About 25% of this is rice husks, a renewable product in great supply.
2. Resysta® looks like wood, and be repaired and treated like wood. It can be drilled, painted, oiled and sawed, with the advantage that it does not splinter.
3. Resysta® is not susceptible to insect infestation. It is water (even saltwater) resistant, slip resistant, and has a lifespan longer than wood.
4. Resysta® comes in a variety of formats, including decking, siding, and facade.
5. Resysta® does not contribute to deforestation.
6. Resysta® is class A fire resistant, will not absorb moisture, and shows no evidence of fungal decay in tests.
7. There have been many synthetic wood products that have come and gone over the years. Although many had excellent structural attributes, they simply did not have the warmth and look of natural wood. This is where Resysta® shines. It looks and feels the woods that are most popular in design and construction.
Channel Lumber carries a variety of Resysta® products. Please contact us for more information.

The Carquinez Bridge which spans the Carquinez Strait between Vallejo and Crocket is actually two bridges. The eastbound span is a cantilever bridge completed in 1958. The westbound span is a suspension bridge completed in 2003, with Channel Lumber providing products and services throughout various phases of its construction.
The original Carquinez bridge was built in 1927, and provided for three lanes of traffic. This was the first major structure built for crossing the bay. Prior to the bridge, Carquinez Strait was navigated via ferry service six miles from the current bridge crossing.
After the Loma Prieta earthquake in 1989, the 1927 span of the bridge was surveyed and deemed no longer safe for passage. At that time traffic was consolidated on the 1958 cantilever span, while the original bridge was demolished.
The new Carquinez Bridge is outfitted with 33 wireless “nodes” which collect and transmit data about the structure. This allows engineers to monitor the bridge closely, and undertake any needed repairs efficiently. The bridge currently operates 8 lanes handling 100,000 cars per day.

In September 2015 Dolby Laboratories opened its new headquarters on Market Street in downtown San Francisco. The building was a consolidation of two separate buildings, one in Potrero Hill, one South of Market. The renovation of the former State Insurance building utilized a significant supply of fire treated Forest Stewardship Council® (FSC®) lumber provided by Channel Lumber.
Dolby Laboratories is known worldwide for creating the seminal circuit which removed unwanted noise and hiss from sound recordings. The circuit was patented in 1969 by inventor and founder Ray Dolby. The name Dolby since has become synonymous with industry leading sound production, and is used widely for sound recordings for movies, and popular music.
Several artists were commissioned in the design of the new facility, and the office transitions seamlessly from open, revolving work space to art installations, infusing the headquarters with creativity and innovation. The traditional cubicle format was abandoned to encourage employees to experiment and express themselves through their work environment.
In addition to sound production, Dolby Laboratories also features on site theaters, and a research facility which, among many, conducts experiments on how sound and media affect human physiology. Current popular releases using Dolby are too numerous to list and include “Ghost in the Shell”, and “King Arthur”.

For a group of employees who affectionately refer to themselves as “Nerds”, the employees of Nerdwallet have one of the hippest HQs in San Francisco. Located at 901 Market the company is housed in one of the most competitive, emerging commercial neighborhoods in San Francisco.
The new Nerdwallet digs can house up to 300 employees, though when they moved in they had roughly 150 employees. The feel of the office is light, with lots of comfortable, non traditional places for employees to meet and break away. Sun filled corners, all window conference rooms, bean bags, all add to this home away from home ambience.
In addition the facility features free yoga and boot camp classes, free catered lunches, and a fully stocked bar (JD81) with over 80 spirits that employees can mix and match. Oh, and of course there is a ping pong table.
Channel Lumber provided a variety of products and services for this visionary project. For more information on how Channel Lumber can help your next project, please contact us.

Channel Lumber provided lumber and services during the construction of the Red Rock Resort in Summerlin, NV. The project was proposed in 2003, and construction completed in 2006.
At the time of the construction, there was little development in the surrounding area of Summerlin. The local zoning was controlled by the Howard Hughes Corporation, and the initial plans were not approved due to the building height, number of condominium units, and light pollution. The plans were changed, and eventually a consensus was reached allowing the project to move forward.
The Red Rock Resort is known as the “local’s casino”, and features an impressive list of amenities and features. The design was an attempt to bring back the ‘modern elegance’ displayed by the classic Las Vegas properties of the 50’s and 60’s. Of note is a 6 million dollar collection of Swarovski Chandeliers of all shapes and sizes throughout the resort. Additionally the art collection has featured Andy Warhol, Robert Indiana, Paul McCarthy, and more. The full service spa hosts a full moon gong/yoga/meditation event for guests, and there is a nightly pool party. The Red Rock Resort has a 72 lane bowling alley and is definitely not your typical casino!
