Check out our top 12 construction time-lapse videos

Today, we’re taking a step back (and up) to offer a unique perspective on some of our most complex projects. Building anything new often takes several years, but nothing accelerates the construction process like a time-lapse video to transform a project before your eyes. The videos below highlight the conversion of an empty space or hole in the ground into something meaningful and impressive.

The World Trade Center Transportation Hub and Oculus

In 2016, the World Trade Center Transportation Hub opened in downtown Manhattan, the culmination of our 15-year journey in restoring and enhancing transportation access to Lower Manhattan. Our team fabricated and erected the hub’s “Oculus” – a Santiago Calatrava-designed structure comprised of approximately 11,500 tons of structural steel consisting of portals, arches and rafters that combined give the structure a unique shape similar to a bird in flight. To erect the Oculus, we used two highly specialized tower cranes manufactured explicitly for this unique project. The Oculus is the centerpiece of the new hub and will serve more than 250,000 pedestrians per day as the primary link for access to New Jersey PATH trains and 11 New York City subway lines. More than a national symbol, the Oculus is a global icon that symbolizes the successful rebirth of Downtown Manhattan.

99M Street, SE

In Washington, D.C., our team is developing and building 99M Street, SE, an 11-story, 234,000-square-foot Class A office building in Washington’s Capitol Riverfront neighborhood just steps from the Washington Nationals Ballpark. Located at the corner of 1st and M Streets, this prime office space will include a green roof and rooftop terrace, a club-grade fitness facility, secure bicycle storage and four levels of underground parking. The complex excavation for 99M began in November 2015 and nearly 500 construction workers have dedicated approximately 51,200 work hours to complete the excavation and foundation work this month. As part of the excavation process 34,000 cubic yards of soil and rock were removed from the site, enough to fill more than 10 Olympic-size pools.

The New York Wheel

In Staten Island, we completed the foundation for the New York Wheel, a 630-foot observation wheel that will rise over the southern end of New York Harbor and provide unique views of the Manhattan skyline. Our team executed two massive concrete placements for the observation wheel pile caps. Each placement saw nearly 4,000 cubic yards of 10,000 psi, self-consolidating concrete that was placed continuously over 14 hours.

Fore River Bridge

In Quincy, Massachusetts, our team transported a custom-built span from a shipyard down the Weymouth Fore River on a custom-built barge to the Fore River Bridge. Then, the nearly three million pounds of steel was lifted approximately 60 feet and installed between the two existing towers as the outgoing tide lowered it into place. A crucial factor was timing the ride of the river, which moves up and down as much as eight feet. The moving tide was necessary for floating in and properly placing the new span.

Philadelphia International Airport

After six months of detailed planning and coordination, we erected a 91,000-pound, 100-foot-long pre-assembled baggage conveyor bridge over the main airport departure road in less than eight hours. The work took place in the middle of the night to minimize any potential disruption to airport operations.

Capitol Tower

In Houston, our 35-story Capitol Tower office project – which is currently under development – started with a 19-hour, 20-minute concrete pour to create a mat foundation that varies between seven and nine-and-a-half feet thick. Our planning and execution of this 9,020 cubic-yard continuous pour was so precise that the actual duration was within three minutes of what we originally planned.

Philip and Patricia Frost Museum of Science

In Miami, we are building the state-of-the-art, 280,000-SF, multi-use science and technology museum, planetarium and aquarium being constructed in Museum Park in the Greater Miami Downtown area. The 500,000-gallon aquarium required a continuous concrete pour that took 24 hours and 49 minutes. This pour sets the foundation for the Gulf Stream Tank that will be home to a number of deep-sea species viewable from both top and bottom.

Recently, we installed a 31-foot, 13-inch thick, 60,000-pound viewing oculus in a complex crane operation that required five years of planning.

Second Avenue Subway

In New York City, our crews dug two-and-a-half miles of tunnels and caverns, set the tracks and installed the communications network for the Second Avenue Subway, which will move an estimated 200,000 people a day. The new line runs from East 63rd Street to East 96th Street connecting with midtown Manhattan and beyond. Excavations for the 86th Street station required the removal of 450,000 tons of material in order to create a subterranean “launch box” or starting point where the tunnel boring machine (TBM) could be assembled and begin its work.

MetLife Stadium

In East Rutherford, New Jersey, we built MetLife Stadium, one of the most sustainable and technologically advanced open-air stadiums with seats for close to 85,000 spectators. The stadium is home for the New York Giants and the New York Jets, which makes it the first facility built specifically to accommodate two U.S. National Football League (NFL) teams. Incorporating innovative methods both in the construction of the facility and in its design, our team worked in collaboration with both franchises to cater to the needs of two different teams.

Tampa International Airport (TIA)

In Tampa, Florida, our team is currently at work on our $130 million portion of the $1 billion Tampa International Airport (TIA) redevelopment plan, which includes the main terminal building expansion, construction of a new car rental facility and the new automated people mover. Last summer, our team unveiled the east side of the expansion, including two new restaurants, glass curtain walls and new, more modern finishes.

LaGuardia Airport

In New York, we are leading the design and construction of LaGuardia Airport through an innovative public-private partnership (PPP), which is the largest in the United States. With our partners, we will design, build, operate and maintain the Central Terminal B facility. Right now, multiple phases of work are being performed on site. The P-2 parking garage demolition has been completed, clearing the way for pile driving and foundation work on the new airport terminal building.

The ultimate sustainability award at I-4: Envision® Platinum

Our I-4 Ultimate Improvement Project has won the prestigious Envision® Platinum award from the Institute for Sustainable Infrastructure (ISI). I-4 Ultimate, the reconstruction of 21 miles of roadway in Central Florida, stands to be the largest project certified by Envision to date. I-4 Ultimate is one of Skanska’s three public-private partnerships (PPPs) in the United States in addition to LaGuardia Airport Central Terminal B in New York and the Elizabeth River Tunnels in Virginia. At Skanska, we are advocates for PPPs because they set the stage for successful sustainability planning by involving all parties – from the architects to the future operators – from day one.

“The entire I-4 Ultimate team is thrilled to receive this recognition for our efforts to protect the environment while creating a signature corridor for the entire region,” said Loreen Bobo, P.E. who is the I-4 Ultimate Construction Program Manager for the Florida Department of Transportation. “This award shows that sustainability goals are achievable alongside other primary missions of our agency to enhance the economic prosperity and preserve the quality of our environment and communities.”

Proposed rendering of the future SR 436 Interchange, which is currently one of the most congested intersections in Florida with more than 100,000 motorists traveling on it per day.

Our PPP team at I-4 Mobility Partners (I4MP) is doing more than building new infrastructure, it is also relocating protected wildlife such as tortoises and osprey, planting native trees such as elms and maples, and recycling 99 percent of the concrete and steel removed from roads and bridges.

Public spaces are being created to connect and engage the community through group sport activities, farmer’s markets, art fairs and parks. Residents will also be able to enjoy enhanced walkability, biking and public transportation options with connections to the SunRail commuter rail system and LYNX, Orlando’s local bus service. All in all, we are fully invested in improving the places where we work and live.

The proposed project design includes accent lighting, illuminated fountains, enhanced bridge architecture and architectural cladding.

“Since day one, our entire team has been committed to achieving the highest standards under Envision,” said Sal Taddeo, Chief Operating Officer East, Skanska USA Civil. “Our goal is to deliver one of the country’s most complex roadway projects while reaching a top level of sustainable infrastructure performance that can serve as a role model for other projects of its kind.”

The road to sustainable infrastructure

Created in 2012, Envision provides a framework for evaluating infrastructure projects similar to how the LEED® evaluation system works for building projects. The ranking consists of a broad range of criteria that address a project’s impact on the surrounding community and environment, technical considerations regarding materials and processes, and other critical choices spanning the project’s lifecycle. There are five categories measured: Quality of Life, Leadership, Natural World, Resource Allocation, and Climate and Risk.

I-4 Ultimate received high scores in three key categories:

Quality of Life: Central Florida’s local history and unique community character are being reflected in the design because there are hundreds of nearby buildings, districts and sites listed on the National Register of Historic Places. Several of these places are within the project limits, including the town of Eatonville, Griffin Park and the Holden-Parramore Historic District.

Founded in 1887, the town of Eatonville was the first incorporated African-American town in the US. The main road — Kennedy Boulevard which passes under the new I-4 project — once served as a wagon trail. Key landscape and historic features will be integrated into the bridge design at Kennedy Boulevard to honor the city’s history.

Leadership: To meet FDOT’s sustainability goals, an agenda was created early in the program to provide the project’s foundation. This includes social priorities such as health and safety, community involvement and business ethics; environmental priorities, including energy, carbon, materials, water and local impacts; and economic priorities such as project selection criteria, supply chain management and value added to society.

Natural World: A comprehensive Contamination Management Plan and Spill Prevention, Control and Countermeasure Plan was developed to prevent pollutants from contaminating soils, surface water and groundwater. Four underground storage tanks and 145 tons of petroleum that impacted soils and debris have been removed from the project site.

Invasive species are being controlled by removing existing Brazilian Pepper trees and Tropical Soda Apple shrubs along the project’s right-of-way while including non-invasive plants for landscaping and maintaining wetland functions.

The native landscaping proposed for this project includes up to 14,225 trees, 9,825 palms and 65,900 native shrubs and grasses.

Setting new sustainability records

In the fall of 2016, our Expo Line 2 Light Rail transit project in Los Angeles received Envision Platinum certification, making it the first transit project to receive the certification. Skanska has been involved in Envision since its inception and we are proud to see that momentum continues to grow. We are a charter member of ISI and we have supported more than 60 employees in achieving the Envision Sustainability Professional designation.

Moving forward, all of our PPPs in the U.S. must be either Envision or LEED certified, and by 2020 all of our U.S. civil infrastructure projects will seek Envision certification.

This marks the first time a Florida project has been honored by the ISI and the second time a Skanska project has been honored.

Thank you to our teammates at I-4 Mobility Partners

Our I-4 Mobility Partners team is designing, building, financing, and operating the project through a 40-year P3 concession agreement with a total design and construction cost of $2.323 billion dollars. We have two roles: one as an equity member through our Infrastructure Development group and a second as part of the SGL Constructors (SGL), which is the Skanska-led joint venture with Granite Construction Company and the Lane Construction Company.

Other members of the I4MP team include John Laing Invesments Limited; Design Joint Venture – HDR Engineering and Jacobs Engineering Group; and Infrastructure Corporation of America.

This week, celebrate the infrastructure on which we all depend

May 12-16 is Infrastructure Week, celebrating the emerging solutions, innovative approaches and best practices in modernizing our nation’s infrastructure, on which the U.S. economy depends. Infrastructure is at the core of what Skanska does,  with projects ranging from public-private partnerships like Elizabeth River Tunnels in Hampton Roads, Va., to transit projects like the Expo Line Phase 2 in Los Angeles. Here’s a look at some of the key numbers associated with these and other infrastructure projects completed or underway by Skanska and our partners:

3CAT210G -Aerial-6 March 2011

The Catskill/Delaware Ultraviolet Light Disinfection Facility uses 56 massive UV units to neutralize waterborne pathogens in New York City’s drinking water supply.

2 billion gallons: Amount of water that can be treated daily at the Catskill/Delaware Ultraviolet Light Disinfection Facility in Mount Pleasant, N.Y. The facility, which was completed last year, is the largest of its kind in the world.

1.5 miles: Length of the 7 Line subway extension in New York City, between Times Square and the rapidly growing Hudson Yards section.

46 minutes: Time it will take to travel between Los Angeles and Santa Monica – even during rush hour – on the Expo Line Phase 2 light rail. When the full line opens, estimated ridership is expected to reach 64,000 daily riders by 2030.

14,600 tons: Amount of blacktop needed to repair 14 miles of Colorado’s Highway 7 after a 1,000-year flood destroyed portions of it in September 2013. Our team repaired the stretch of highway over six-and-a-half weeks, with crews working 12 to 14 hours a day, seven days a week to finish the road ahead of schedule.

442 feet: Length of the tunnel boring machine – nicknamed Lady Bird – that our team is using to bore a 13-mile tunnel 100 feet under Washington, D.C., to hold sewage awaiting processing at the Blue Plains Advanced Wastewater Treatment Plant.

21 miles: Length of the stretch of Interstate 4  in Orlando, Fla., for which the I-4 Mobility Partners team  – of which Skanska is a part – has been selected to design, build, finance, operate and maintain improvements through a P3 agreement. This P3 approach will enable the Florida Department of Transportation to deliver these essential highway improvements – including reconstruction of 15 major interchanges and replacement of more than 75 bridges – 20 years sooner.

Skanska’s bridges by the numbers

Bridges are some of our most eye-catching projects. We build and rehabilitate bridges of all types, from landmarks like the Bridge of Lions in St. Augustine, Fla., to interstate thoroughfares like Interstate Highway 10 over Florida’s Escambia Bay. We’ve overseen the seismic retrofitting of the Richmond-San Rafael Bridge in California, construction of the Cooper River Bridge (also known as Arthur J. Ravenel Bridge) in South Carolina, as well as worked on the iconic East River bridges in New York: the Brooklyn Bridge, Williamsburg Bridge, Manhattan Bridge and Robert F. Kennedy Bridge (formerly the Triborough Bridge).

In celebration of these feats of engineering, here is a look at some of Skanska’s bridge projects, by the numbers.

155 miles per hour: The speed of Hurricane Ivan’s winds that ruined sections of the Interstate Highway 10 twin bridges between Florida’s Escambia and Santa Rosa counties in 2004. Skanska designed and constructed two replacement bridges to stand 25 feet above water, more than twice the height of the original bridges.

215 feet: The height of the Bayonne Bridge after a Skanska joint venture raises the roadway by 64 feet. The bridge’s current 151-foot clearance cannot accommodate the next generation of new Panamax container ships, which will begin service from Asia by about 2015, following the widening of the Panama Canal.

1883: Year the Brooklyn Bridge, one of the oldest suspension bridges in the United States, was completed. We’re currently reconstructing the approaches and ramps in both Manhattan and Brooklyn.

35,000 tons: The amount of waste concrete and asphalt, together with 5,400 tons of recovered steel, that the Skanska team recycled at our 11th Street Bridge replacement project in Washington D.C. Our design-build team performed 70 percent of construction without affecting existing traffic flows.

78,000 vehicles: The number of cars, trucks and motorcycles that cross the Manhattan Bridge each day. The 5,800-foot-long bridge, which spans the East River between the boroughs of Brooklyn and Manhattan, was built in 1909. Years of use caused rapid deterioration to this historical and architectural monument, forcing the New York City Department of Transportation to initiate a massive reconstruction program. Skanska rehabilitated the bridge’s north spans.

2.5 miles: The length of the Cooper River Bridge. Skanska completed this design-build project in Charleston one year ahead of schedule. The 1,546-foot main span, which is 186 feet above the river, is one of the longest cable-stayed spans in North America.

17.6 miles of bridge/tunnel: The length of over-and-under water Chesapeake Bay Bridge Tunnel, one of the Seven Engineering Wonders of the Modern World. We built the bridge-tunnel over three-and-a-half years through a joint venture with four other contractors.

25 feet: The height of Los Angeles’ Gold Line Bridge’s basket-like concrete columns that pay tribute to the indigenous people of the San Gabriel Valley and the oversize iconic roadside traditions of nearby Route 66. Skanska completed the 600-foot-long bridge in 2013.

3.3 million lbs: The weight of the steel Skanska used to strengthen the 350-foot tall main towers of the Williamsburg Bridge, during its rehabilitation and seismic retrofitting. Intermediate towers were strengthened with 1.8 million pounds of steel.

31 million lbs: the weight of extensive structural steel retrofit added to the Richmond-San Rafael Seismic Retrofit Project in California, which included the strengthening of the four-mile long bridge’s truss components and tower legs, the installation of special moment resisting pier frames, installation of seismic isolation bearings, viscous dampers, and seismic restrainers.

Building California’s Gold Line Bridge: Spanning cultures, a fault line and a freeway

Our recently completed Gold Line Bridge northeast of Los Angeles invokes that region’s heritage, making a strong case that cost-effective infrastructure doesn’t have to carry a utilitarian look. The nearly 600-foot-long concrete span, to carry a light rail line, is anchored by two, 25-foot-tall basket-like concrete columns that pay tribute to the indigenous people of the San Gabriel Valley and the oversize iconic roadside traditions of nearby Route 66. The $19.8 million bridge’s aerial guideway features intricately cast grooves and ribbing that mimic the patterns found on the Western Diamondback snake.

“We were always emphasizing to the craft workers how important it was to get the details right,” said Lawrence Damore, Skanska’s project executive. “The quality of work these crews produced exceeded everyone’s expectations.”

But those architectural elements were not the most challenging part of the bridge, which was our first civil infrastructure design-build project in California. Rather, the toughest aspect was erecting the structure in a small footprint over the active I-210 freeway, which is five lanes wide at the bridge’s location. An additional hurdle is that the bridge spans an active earthquake fault; the seismic requirements necessitated more reinforcing bars, more post-tensioning and higher-strength concrete.

The worlds of infrastructure and art do not often get to mix, but the Gold Line Bridge demonstrates that, when both groups agree on a vision, the utilitarian and the artistic can push each other to achieve both functional and aesthetic success.

In New Jersey, raising a bridge to bolster the national economy

On June 26, a crowd of hundreds of Skanska employees along with union workers and community members gathered with New Jersey Governor Chris Christie to celebrate the beginning of the historic Bayonne Bridge “Raise the Roadway” project.

The Skanska-Kiewit joint venture project team will raise the roadway on the Bayonne Bridge by 64 feet for a total of 215 feet of clearance. This will be essential in accommodating the next generation of container ships, called “New Panamax,” which will begin shipping from Asia following the widening of the Panama Canal by 2015. The bridge’s current 151-foot clearance would be an obstacle for allowing these larger ships to pass into the marine terminals west of the bridge.

“Not only will our project achieve a new era of greatness for our port, but a new era of greatness for this region as well,” Christie said during his address.

Bayonne 1

The Bayonne Bridge is the fifth-longest steel arch bridge in the world and connects Bayonne, N.J., with Staten Island, N.Y. It opened in 1931 and was named a National Historic Civil Engineering Landmark in 1985. Throughout this project, the bridge’s original arch will remain intact.

“The raising of the navigational clearance at the Bayonne Bridge has great historical and economic significance,” said Paul Koch, Skanska vice president. “Through this project we are preserving the historic structure while ensuring the future vitality of the of the area shipping ports by preparing for the larger, modern-era ships.”

The project will position the region to remain a leader in the shipping industry. It will secure the thousands of jobs and billions of dollars in commerce that the industry currently brings to the region.

“We are going to get this bridge done and protect the jobs of the people of the state of New Jersey,” Christie said.

The project is not only important to the Northeast region. In July 2012, it was announced that it would be included in the Obama Administration’s We Can’t Wait initiative, because it is both nationally and regionally significant.

The Bayonne Bridge will remain open throughout this project. Our team will build the raised roadway over the existing roadway, which will continue to be used until it is removed after the completion of the new, higher roadway. The project’s first milestone – the 215-foot clearance and partial opening of the new raised roadway – is expected to be reached in December 2015. The project is expected to be completed in May 2017.

Building a bridge? Here’s a checklist for maximizing its benefits

Case Study: Involving the community

Location: Cooper River Bridge, South Carolina


1) Construct the longest cable-stayed bridge in North America in a way that maximizes the benefit to surrounding communities and the local economy, while protecting and enhancing wetland environments.

2) Remove two obsolete bridges and erect a 2.5-mile, eight-lane bridge, and avoid disturbing the environmentally sensitive area.

Bridge constrcution

How do you make the most of that situation?

1. Select a design that will last a century.

2. Use models and simulations to evaluate the effects of design options on the ecosystem of the Charleston estuary.

3. Apply the lessons learned from similar projects, such as the Öresund Bridge – the 10-mile road and rail tunnel/bridge connecting Denmark and Sweden. Since the Öresund Bridge project is very similar, utilize members of its project team to draw on their experience.

4. Starting early in the process, establish close cooperation with local authorities and organizations to maximize the utility of the bridge, and quickly address social and environmental issues before they turn into difficulties. Encourage dialog with local participants, including government officials, organizations and residents. Maintain this dialog throughout the construction process.

5. Based on the dialog, select diamond-shaped towers from among several options and add a pedestrian walkway and bicycle lanes to the bridge.

6. Maximize the use of local construction workers and suppliers.

7. Create task forces across agency borders to advise on particular issues. For example, have the U.S. Army Corps of Engineers monitor the demolition of the old bridges, and ensure that the wetlands are protected and enhanced by involving the U.S. Fish and Wildlife Service and the South Carolina Office of Ocean and Coastal Resource Management.

8. Choose lighting that minimizes impact on sea turtles and migratory birds.

9. Restore wetlands. Reuse material from the demolished bridges to create new, artificial reefs along the coast.

10. To avoid erosion, reforest the construction site as soon as possible.
