he Gerald Desmond Bridge has been the main gateway to the Port of Long Beach, downtown Long Beach and surrounding communities since its construction in 1968. Referred to as, ‘America’s gateway to the Pacific Rim’, the bridge has served the nation well, with nearly 15 percent of all waterborne cargo passing across its deck annually. After almost a half a century, the Gerald Desmond Bridge had reached its intended life span, and with signs of deterioration and low inspection ratings, the decision was made to replace it with the first ever cablestayed bridge in California that will be among the tallest of its kind in the country. The existing bridge has remained in use during construction and will eventually be demolished once the new bridge is completed.

The Gerald Desmond Bridge project is being constructed as a joint effort between Caltrans and the Port of Long Beach, with funding support from the U.S. Department of Transportation and the Los Angeles County Metropolitan Transportation Authority (Metro). The project is being led by joint venture, SFI, which is comprised of Shimmick Construction Inc., FCC Construction, and Impregilo S.p.A. Oakland based Shimmick Construction is a veteran of large infrastructure projects, working on some of the most noted landmarks in and around California for 23 years. Among their credits are jobs like the retrofit of the Golden Gate Bridge, and the extension of the Los Angeles Metro East Side light rail system. FCC Construction is headquartered in Spain, and they have built a reputation for using the latest technology

to engineer and build large and complex infrastructure projects. They have built more than 3,280,840 square feet of bridges in the past 15 years, including everything from stationary and drawbridges made of steel, to concrete and mixed material bridges. Impregilo S.p.A. has been one of Italy’s premier builders since 1906, with a worldwide portfolio that includes dams, hydroelectric power plants, railways, subways, tunnels, bridges, viaducts, highways, roads, ports, and airports. Some of the key subcontractors on this mammoth project include Arup (lead designer), CMS Rebar and Rebar of Santa Fe Springs, Stinger out of Arizona (structural steel fabrication and steel erection), and A&A Concrete. With an approximately $1.5 billion price tag, the Gerald Desmond Bridge is one of the largest infrastructure

The current 1.5-mile-long Gerald Desmond Bridge spans the Back Channel in the Port of Long Beach (pictured right), and the bridge under construction circa 1967 (pictured left). Named after a former city attorney and councilman of the city of Long Beach, the bridge was completed in 1968.

Workers monitor “the Big Pour,� where more than 3,200 cubic yards of concrete were poured into the pile cap for Tower 17, one of two 515-foot-high columns that will support the main span of the new bridge. It took more than 300 truckloads of concrete to get the job done.

Continued from page 6 projects currently underway in California. When completed in 2018, the new bridge will have a 205-foot vertical clearance to accommodate even the largest and newest generation ships. The new bridge will also be wider with three lanes in each direction, as well as emergency lanes on both the inner and outer shoulders to reduce traffic delays. There will even be bicycle and pedestrian paths, complete with three scenic overlooks. The manpower, equipment, materials, and supplies needed to accomplish this mammoth task are

staggering, to say the least. More than 300 construction workers can be found working on the bridge on any given day, and by jobs end, they will have erected more than 90 million pounds of steel and 300,000 cubic feet of concrete. In September 2015, the first pile cap was poured, enabling crews to begin constructing the first of two 515-foot towers needed to connect the cables to the road deck below. According to reports, around 2,240 square feet of rebar was utilized in the construction of the first pile cap, an elaborate and carefully designed structure that took more than six weeks to build.

The pile cap is around two stories high and it serves as the base for one of the 515-foot towers. It is essentially a thick concrete pad that connects to and sits upon around a dozen foundation piles, giving it the strength needed to support the bridge column. This particular pour began on a Monday at 8 p.m. and did not finish until the following morning at 8 a.m. More than 300 truckloads from two separate plants poured 3,200 cubic yards of concrete into the initial pile cap, a procedure that required a bit of timing and logistical skill. When completed, more than 350 reinforced concrete foundation

piles that have been excavated and placed as far down as 190 feet will support the new bridge. Rising from these piles is two towers and more than 90 columns, all needed to support the road deck. The technique used here is different from traditional pile driving, where the piles are constructed and then driven into the ground. These are “cast-in-drilled-hole� (CIDH) piles where grout and concrete are injected into the borehole under high pressure. The new Gerald Desmond Bridge will be the tallest structure in the Long Beach skyline and it will serve as an icon of quality and achievement for the port authorities, the City of Long Beach and surrounding communities. Its twin towers will soar 50 stories high, with a 1.5-mile roadway that will serve and support motorists more than 200 feet above the water. There is still work to be done, however, before the new bridge opens in 2018, and then

there is still the demolition of the existing bridge to contend with. The new Gerald Desmond Bridge is only one part of a more than $4 billion improvement plan designed to further modernize the Port of Long Beach. The long-term strategic plan includes designs to bring the most automated container terminal in North America to the Port of Long Beach, as well as a $1 billion plan to expand on-dock rail capacity and supply-chain optimization. What began as a single railroad track built upon a wooden trestle back in the late 1800s is now a $1.5 billion beacon of hope and prosperity that will serve motorists and industry into the next century. The bridge is also one of several design-build projects currently underway in the State of California. The Gerald Desmond Bridge has been designated as a National Highway System Intermodal Connector Route and a part of the Federal

Strategic Highway Network. It is a critical structure that will serve California and the nation for many years to come. The project has not been without its challenges, however, the positive impacts far outweigh any of these temporary setbacks that have occurred along the way. Work on the new bridge has generated an estimated 3,000 jobs each year and the

change from four driving lanes to six will certainly make the estimated 68,000 vehicle trips a day and 18 million trips a year easier and more enjoyable.

I-210 Freeway Pavement and Slab Replacement Project Heading For the Home Stretch By Brian Hoover, CMS, Senior Editor

Above L to R: Miguel Posada, Noah Ornstein, John Stich and George Warren, Completely Concrete Structures, Inc.

Above: Map of I-210 Freeway and Pavement Slab Replacement Project. The effort will improve nearly 10 miles or 90 lane miles on the I-210 Freeway.

California Interstate 210, also known as the Foothill Freeway, was planned clear back in the 1940s, commissioned in the 1950s and then constructed in stages primarily from the 1960s to the 1980s. The state route section known as California 210 was completed in 2007, allowing for the combination of Interstate 210, California 210 and California 30 to provide a continuous freeway link from Los Angeles (San Fernando Valley) to Redlands. California

State Assembly Bill AB 2388 eliminated SR 30 in 1998, however signage references were not completely eliminated from all freeway segments until 2009. The Interstate 210 portion (Foothill Freeway) now runs between Interstate 5 in Sylmar and California 57 in Glendora via Pasadena. At this point, the name changes to California 210 and continues east to San Bernardino, ending at Interstate 10 in Redlands. It is not clear when and if Caltrans plans to

2017 Concrete Construction ISSUE CALCONTRACTOR

designate the entire freeway system to the Interstate 210 freeway any time soon. Certain sections of concrete pavement on the I-210 Freeway have been deteriorating since they were first paved in the 70s and required replacement. In an effort to improve nearly 10 miles (90 lane miles) of the I-210 Freeway, Caltrans awarded a $148.5-million project to Chino Hills-based Flatiron West, Inc. The multi-million dollar project will specifically improve freeway sections spanning from La Crescenta to Pasadena. The job began in the spring of 2015 and is scheduled for completion in the spring of 2018, however the current pace of work could bring about an earlier completion date. The job was broken into four phases, the first of which involved the replacement of freeway median barriers and guardrails. This work began in April 2015 and continued into the beginning of 2016. Phase 2 and 3 involved the removal and resurfacing of concrete lanes in 1 ½-mile segments. Additionally, LED lighting and high-friction surface treatments were made to the tunnel near the Foothill Freeway and 134 Freeway. Phase 4 will reportedly involve the replacement of signs and striping throughout the nearly 10-mile section. The finished project replaces lanes 3 and

4 entirely, repairs lanes 1 and 2 as needed and replaces the median barrier. The upgrades to the overhead signage will reportedly allow for higher wind loads and more sign reflection, requiring less additional lighting. There will also be upgrades made to the current drainage system, allowing for more capacity and improved flow, as well as the installation of loop detectors and upgrade of curbs a various locations to meet all ADA requirements. In order to increase efficiency and minimize crew’s exposure to traffic, Caltrans specified the use of precast concrete pavement slabs in certain areas of the I-210 Freeway. Flatiron West, Inc. contracted with Oldcastle Precast of Fontana to supply several thousand precast slabs for use on the $148 million project. Specifically, the contract called for 6,500 precast concrete pavement slabs in 12.5-foot-wide by 11.33-foot-

16

long by 12-inch-thick sections for areas throughout the 9.7mile segment of Interstate 210. In an effort to avoid the heaviest traffic cycles, the highway areas in question were closed at approximately 9 p.m. and reopened by 5 a.m. the following morning. During the overnight construction, crews began by cutting out the deteriorated sections, followed by the addition of a lean concrete base into the excavated segment. The lean concrete then requires approximately 1-hour to achieve required strength, before the precast concrete pavement slabs are installed. Reportedly, around 280 slabs have been set each week, with approximately 630-linear-feet going in each night of construction. In total, approximately 200,000 cubic yards of precast and cast in place concrete will be utilized on the overall 9.7-mile section of the I-210 Freeway.

2017 Concrete Construction ISSUE CALCONTRACTOR

Precast concrete highway pavement slabs are currently being used by several state departments of transportation throughout the United States. The efficiency of these pavement slabs has been proven through the implementation of successful demonstrations on Freeways throughout California. Although precast panels are said to be initially more expensive than cast-in-place, they are also reported to be more durable. Another reported benefit to using these precast pavement slabs is the fact that they can be installed in any weather scenario, with an estimated life expectancy of 50 years. So, in the long run, its use may require less time and fewer maintenance closures, making them less expensive and easier to work with. According to experts, installing a precast concrete panel can be trickier than it may appear. There are

many factors such as grinding and leveling that can make the process more of a challenge. To make the entire process easier, a Caltrans maintenance supervisor developed a leveling lift designed to install the panels faster and without the need for extensive grinding. Evidently, a screw-like mechanism allows the panel to be raised and

www.calcontractor.com

lowered, while grout is used to achieve the necessary depth. The use of this seemingly simple leveling lift has allowed Caltrans to improve from a typical nightly installation distance of 124 feet to an astounding 500 feet of repairs per night. It should be noted that the leveling lift is not yet being widely used by Caltrans,

however with every successful demonstration, the device could soon be used on a regular basis. When the project is completed in 2018, the new concrete surface will not only provide a smoother drive for motorists, but it will also reduce the need for further maintenance and minimize dreaded lane closures in the future.

Largo Concrete, Inc. Is On A Run With More Than 800 Structural Concrete Projects Completed Since 1989 By Brian Hoover, CMS, Senior Editor

Above & Left: Largo Concrete, Inc. will pour 33,043 cubic yards of concrete before completing the 8th & Spring Tower Project in Downtown LA in Nov. 2018.

Largo Concrete, Inc. (Largo) has completed more than 800 structural concrete projects over the past 28 years. Founded in 1989, as a privately held, full service structural concrete contractor, Largo has over 1,450 employees, and has made a name for themselves on a variety of projects, including parking structures, high-rise residential/mixed use structures, hotels, podiums, commercial buildings, hospitals and schools all throughout Northern and Southern California. Mark Carnathan, Northern California President and Ken Long, President, head the Northern and Southern California divisions, respectively. Co-founder Mark Carnathan has 37 years of concrete construction experience and Ken Long has been with the firm for 23 years. Largo averages over $300 million a year in volume and the past few years have been full of growth and promise. Here are just a few of the jobs that Largo is currently on or recently completed.

8th & Spring Tower Construction Holland Partner Group, a developer out of Vancouver, broke ground on a 24-story tower on South Spring Street in spring 2016. In October 2014, the developer purchased a 39,000 square foot parking lot for $12.5 million on the northwest corner of 8th and Spring Street with intentions of building a 244-foot tall mixed use structure. The new building is currently under construction and sits between the Historic Core and the Fashion District, just about three blocks from Skid Row. Holland Partner Group’s residential division (Holland) is building the 283,251 square foot structure, dubbed 8th and Spring, at 755 South Spring Street. The project is one of several buildings that Holland is developing in this particular area, but this site will house a 320-unit apartment complex, designed by Irvine’s MVE & Partners. The complex will also include 8,900 square feet of retail

2017 Concrete Construction ISSUE CALCONTRACTOR

space, as well as a rooftop deck and pool. The project sits on 0.89 acres and is expected to have 18,500 square feet of first floor commercial space, along with some of the retail space also encompassing the second floor with the remainder built out for vehicle parking. The sixth floor is where the fun and social activities will be, with 21,790 square feet of common space. This area will include a pool, spa, barbecues, outdoor lounges, a fitness room, and a club room. The roof level will also offer 5,575 feet of open space and a beautiful view of the City of Los Angeles. The project is scheduled for completion sometime in 2018. Mike Daniel is a project executive for Largo Concrete, Inc. On the front end of this particular project, Daniel is focused on the contracting, preplanning, and formwork systems, while working closely with the field teams. “I track our progress throughout the project, keeping our goals in mind and doing everything I can do to assure that our teams have what

they need for a successful project, while also focusing on our client’s continued satisfaction,” says Daniel. “It is amazing to see what our crews can do on a daily basis on a project like this. This job is so very well organized and planned and that effort translates to success on safety, schedule, cost and client satisfaction. I couldn’t be more proud of our team and would like to thank all of them for their extraordinary efforts, with special thanks and recognition going to field supervisors, who have done such a great job leading the crew.” Mass excavation on this project began in April 2016, and Largo began their work May 25, 2016, with completion set for the end of November 2018. During this time, Largo will pour approximately 33,042 cubic yards of concrete provided by Associated Ready Mixed Concrete. There were three mat foundation pours that took place overnight, and on weekends that ranged in size from 1,460 cubic yards to 2,880 cubic yards. “In the tight historic core of Downtown LA, it was just not practical to place these foundations during the busy weekdays on the crowded downtown streets,” says Daniel. Largo and its subcontractors peaked out with a crew of 65 skilled tradesmen, as they

20

finished up the podium and pool deck area. According to Daniel, schedule and logistics presented a big challenge as Largo moved through the below grade parking structure. “Constantly sloping decks, shotcrete perimeter walls, and the amount of specialized wall and column formwork on this project took up a lot of room within the building footprint, which became a constant,” says Daniel. “Column forming, which is usually straight forward on a high-rise, was particularly challenging on this project because the columns were odd dimensions and completely changed shape and dimensions frequently requiring us to swap out.” Daniel also points out that this is the first project where Largo used 3D scanning technology to create “as built” data for the entire structure and to monitor building movements throughout construction.

732 Spring Street The second of these high-rise towers to be erected is a 250-foot building at 732 S. Spring Street. The $164-million project consists of a 24-story tower, which will feature 300 apartments, 7,500 square feet of ground-floor retail space, and numerous other amenities. It follows the sister project across the street at 755

S. Spring Street (8th & Spring), which broke ground in late 2015. Both towers are located on the border of the Fashion District and Historic Core, and feature designs that take inspiration from the characteristics of both neighborhoods. Both towers were designed by MVE + Partners, and are notable for featuring above-grade parking structures masked by usable space. Future residents will have access to amenities at both properties, including an outdoor swimming pool, a pocket park, a fitness center and a rooftop deck with sweeping views of the city. Mike Daniel was also the project manager for Largo on the 732 S. Spring Street project. Mass excavation began May 27, 2016, and Largo started their portion of work Aug.19, 2016. They are scheduled to be finished in December 2017, with the entire project buttoning up on Jan. 18, 2019. When completed, Largo will have placed 29,878 cubic yards of concrete (provided by Holliday Rock), with the 3,640 mat pour being the largest single installation. “Hoisting time on a project like this is always a challenge,” says Daniel. “Once the building structure is moving along, the added activities of installation of the

pre-cast concrete skin start. At that point, there are competing critical activities that need to use the tower crane.” Daniel also points out that because of the pressures on the hoisting, they chose to use self-climbing wall formwork that can operate without the assistance of the tower crane. “The crews have done a phenomenal job on this project. There were a lot of challenges and unique geometry to getting out of the ground and into the residential tower portion of the project,” says Daniel. “Throughout these challenges, the crews were able to track ahead of schedule. The attention to safety and the safety attitude of every worker on this project is one of the best I have witnessed.”

Circa Project Work began on the $500 million mixed-use Circa project back in August 2015 and residents should begin moving into their new luxury digs sometime in early 2018. The new development located at 1200 S. Figueroa St. in Los Angeles will include the construction of two high-rise buildings that combined will offer 648 luxury condominiums that will sit on top of a 100 foot tall, seven-story retail podium with 48,000 square feet of space for restaurants and shops,

22

along with 1,770 parking spaces. The residential offerings include one- and two-bedroom units and penthouses, from 700 to 4,000 square feet, with rents ranging from $3,000 to $25,000 per month. A two-acre amenity deck is said to include a round lounge pool with private cabanas, two dog parks, a fitness building equipped with a lap pool and indoor/outdoor Pilates/yoga facilities. Other amentities include a clubhouse, complete with an indoor bar, a dozen event screens, private chef’s kitchen and dining room, business center and library-wine bar. There will also be a 17,000 square foot ribbon of LED signage along Figueroa Street. The twin 35-story tower, known as Circa, is located across from the Los Angeles Convention Center and is being developed by Hankey Investment Company, Jamison Services, Falcon California Investments and Highlands Capital. LendLease is the construction manager on this project, with Cary Kopczynski & Company (CKC) serving as the structural engineer and Wilshire Construction as the general contractor. The curved tower design comes from the architectural firm, Harley Ellis Devereaux, and it features elliptical floor plates and swooping

2017 Concrete Construction ISSUE CALCONTRACTOR

rooflines inspired by the adjacent Staples Center. Each tower will stand 420 feet high and although each building will appear identical from the outside, the lobbies have been designed with contrasting themes based on natural elements. The north tower will reportedly feature marble forms, modeled after icebergs, while the south tower features softer, undulating shapes inspired by sand dunes. Largo began putting down the first of a half dozen mat pours in July 2015, the largest of which was approximately 5,000 cubic yards. When Largo was finished with their work in June 2017, they had poured more than 110,000 cubic yards on what, Largo project executive, Donald Kahn, describes as one of the more challenging projects in recent history for the company. “There are so many mega projects going on in Downtown LA right now and logistically this job was quite a challenge with tight quarters and even tighter deadlines,” says Kahn. “Between two 35-story towers and an 8-story garage, we had crews working 14 to 16 hour days, pouring concrete around the clock and putting forth a very well orchestrated effort.” According to Kahn, the two towers were being built within a time separation of five days, and they were turning

over around 35,000 square feet every nine days. “Follow-along trades were five to seven floors behind us, chasing us from one floor to the next,” says Kahn. “We take a lot of pride in the fact that we placed so much yardage under such extreme conditions. It was really quite an achievement, a high profile project in the middle of all of the LA construction going on right now. I am very proud of our crews and all of the trades that we worked with along the way.” Kahn also points out that the project was made a little easier through the professionalism, knowledge and experience they received from their concrete supplier, Holliday Rock. “We were dealing with Modulus of Elasticity (MOE) requirements, and Holliday Rock did a great job with all of the thermal and high strength mix designs and requirements on this project. The job called for high strength mix designs in excess of 9,000 psi and Holliday was very helpful in getting us through the entire process.”

New $1.3 Billion Wilshire Grand Center Open For Business as Tallest Building in Los Angeles and World Record Holder For Largest Continuous Concrete Pour

From foundation to spire, the Wilshire Grand Center sets records By Brian Hoover, CMS, Senior Editor – and standards – for construction. The Wilshire Grand Center in downtown Los Angeles now stands as the tallest building west of the Mississippi river. It also holds another grand honor in the Guinness Book of World Records as the project with the largest continuous concrete pour. The new tower stands 1,100 feet tall with 73 magnificent stories that pushed the US Bank Tower next door to the number two spot. The new skyscraper is more than 80 feet taller, thanks to the iconic 295-foot steel spire that sits atop of the 1,100-foot structure. As of June 23, the new $1.3 billion

mixed-use development opened for business after more than three years of construction. The 73-story structure stands on the former site of the historic Wilshire Grand hotel that closed back in 2011 and was developed by Korean Hanjin Group, which owns Korean Air Lines. The general building contractor was Turner Construction Company, with Brandow & Johnston serving as the structural engineer of record and A.C. Martin in charge of design services. Some of the specifics include 400,000 square feet of office space, 900

luxury hotel rooms and more than 45,000 square feet of retail space. Other amenities include restaurants, bars, ballrooms, observatory and sky pool decks, a 70th-floor sky lobby, and an underground parking garage that can accommodate 1,250 vehicles. According to the contractor, more than 2,200 individuals worked over 257 weeks placing more than 22,000 tons of steel, over 55,000 cubic yards of concrete, and 500,000 square feet of glass. In February 2014 the project recorded a recordbreaking continuous concrete

mat pour that took more than 20 hours to complete. An official adjudicator from Guinness World Records was on the scene to confirm the record that beat the previous record of 14,000 m3 (494,400 ft3), set in 2006 at the Federation Tower in Moscow. The three-day pour began Feb. 15, 2014, at 5 p.m. as Turner Construction Company utilized 400 workers, eight batch plants, 19 concrete pumps, and 208 mixers to place more than 2,000 truckloads. The 18-foot thick mat foundation consumed and amazing 21,600 cubic yards of concrete that weighed more than 82 million pounds. Other interesting aspects of the Wilshire Grand Center construction project include the use of hybrid technology where a combination of structural steel, reinforced concrete and Buckling Restraint Braces (BRB’s) were used together to resist lateral forces, similar to those created during an earthquake. Additionally, 700 prefabricated bathroom pods were trucked in and hoisted and bolted down all in the same day of construction. The project team also earned Golden Gate recognition from Cal/OSHA for their site safety program, as well as several other awards from the state and local level.

CALTRANS RELEASES PLAN FOR THE REOPENING OF HIGHWAY 1 AT MUD CREEK

Above: Highway 1 at Mud Creek after massive landslide. Caltrans recently released plans detailing strategy to rebuild and reopen Highway 1.

BIG SUR, MONTEREY COUNTY – Caltrans recently released plans detailing its initial strategy to expedite the rebuilding and reopening of Highway 1 at Mud Creek. Department officials announced that a new roadway will traverse over the site of the massive Mud Creek slide. The new roadway will be realigned across the landslide and will be buttressed with a series of embankments,

26

berms, rocks, netting, culverts and other stabilizing material according to department engineers and geologists." Our staff has been working hard to tackle the weatherrelated challenges faced by Highway 1,”said Malcolm Dougherty. “We have made tremendous progress on Pfeiffer Canyon, have opened Paul’s Slide and now we have good news on the slide at Mud

2017 Concrete Construction ISSUE CALCONTRACTOR

Creek. Our goal is to reconnect the areas impacted by the winter storms as quickly and safely as possible.” This strategy will allow Caltrans to rebuild the roadway more quickly and at a lower cost than other alternatives such as structures, a tunnel or major earthwork that places additional fill into the ocean. “This plan is a win-win for the hard-hit Big Sur community and this pristine coastal environment,” added Caltrans District 5 Director Tim Gubbins. “Our emergency contractor continues working dawn to dusk every day and will continue until we can safely reopen the highway.” Caltrans sent its initial roadway rebuilding plan to various state, local and federal resource agencies last week and will continue to work closely with them and the Big Sur community until the highway is reopened. The landslide occurred on May 20, dumping more than 5 million cubic yards of material onto the roadway and into the ocean, making it the largest slide ever along the Big Sur coast. Caltrans’ expects having a timeline for reopening and anticipated cost details by the end of August. A news media opportunity will take place Thursday, Aug. 3. All interested media meet at Ragged Point Inn on State Route 1 at 10 am sharp. Media is required to bring/wear safety gear:hard hat, vest, boots and safety glasses. RSVP is recommended. Cc
