Contractor Overcomes Challenges on Yulman Stadium
18 August 2014
Engineering News Record highlights Woodward Design+Build’s work on Tulane’s new football stadium as opening day for Yulman Stadium nears. ENR’s story draws attention to the project’s small footprint within a dense neighborhood, the tight timeline, and the obstacles and delays that Woodward has overcome in order to prepare the stadium for its September 6 opening game.

Building a collegiate football stadium for 30,000 spectators is no easy task, but doing it in a small footprint in a residential neighborhood and on a short schedule takes skill and experience. After facing hurdles and delays well before groundbreaking, a New Orleans contractor is making a mad dash to finish Tulane University’s stadium in time for the football team’s season home opener in September.
Small Footprint, Tight Timeline
The $63-million Yulman Stadium will be the university’s first on-campus stadium since historic Tulane Stadium was demolished in 1980. From 1926 to 1975, the old structure hosted the Tulane Green Wave, the New Orleans Saints and three Super Bowls.
The 30,000-seat stadium is being constructed in a tight spot on the university’s campus in Uptown New Orleans. Space is so tight that the stadium ties into existing buildings on one end and sits 20 ft from neighborhood backyards on the other end. The project is 95% complete as of early August. The entire structure is in place, the field is compacted and prepared to receive turf, and interior facilities, such as press boxes, bathrooms, concession areas and meeting areas, are being finished, says Ken Flower, vice president of general contractor Woodward Design+Build.
Yulman Stadium has a number of amenities, including the Glazer Club VIP area designated for premium donors. It will feature 1,500 chair-back seats, two giant clubrooms with direct field views, a bar and a large gathering space. The covered, open-air Westfeldt Terrace offers rail seating on the concourse edge, 3,000 seats with backs and another premium concession area. There’s also a 94-ft by 24-ft LED scoreboard and a top-of-the-line synthetic turf field.
Woodward has faced a number of unforeseen delays and is making a tight run to finish by the Sept. 6 season home-game opener, but Flower is confident they’ll get it done by then. The contractor has been working seven days a week, with extensive overtime.
“It’s a tight schedule with the challenges we’ve had, but that’s the plan, and we’re aiming for that deadline,” Flower says.
Community Concerns Add to Delays
The stadium project hit a number of delays before it even broke ground. Yvette Jones, Tulane’s executive vice president for university relations and development, says there were years of planning and research leading up to construction of the stadium. After site analysis and a land-use survey, architects came up with a 30,000-seat design that would fit on the school’s existing track and tennis facility.
Tulane brought on Woodward Design+Build as the general contractor in spring 2013 but immediately encountered pushback from the community. The city of New Orleans would not allow the team to pull permits for anything, even demolition, until they met with community groups to discuss issues such as water management, parking, trash pickup and usage.
“We got into the city process in May 2013 and didn’t get a final agreement until January 2014. It reduced the building schedule to only 18 months,” says Jones.
Flower says they’ve had to be “very sensitive” with the neighboring communities. They’ve had to route trucks and equipment down certain streets. During the demolition and pile-driving, Woodward went above and beyond its typical quality-control inspections for things like vibration and noise. Since the area was once a cypress swamp, crews had to drive more than 3,800 timber and precast concrete piles for the stadium’s foundation. Flower says they also had to remove a number of large cypress stumps and move the piles.
“It added to the delays and was a big challenge. We worked closely with the engineers to drive new piles, redesign on the fly and move pile caps,” he says.
The visitors’ side of the stadium sits only 20 ft from the property line of adjacent homes. Tulane installed a service road there as a buffer and worked with architects Gould Evans & Associates, Kansas City, Mo., and locally based Lee Ledbetter & Associates to keep a low profile.
Flower says the stadium was designed to minimize light and noise pollution during games and events. The shape and pitch of the stadium helps push noise upward instead of outward, while light placement and angles were adjusted to illuminate the stadium and minimize light overflow into the neighborhood.
Jones says Tulane and its community liaison work closely with neighborhood groups to resolve issues on the project and serve as the go-between with Woodward. The contractors and school meet biweekly to address not only construction updates but also current issues with the neighborhood.
“It has been tough [on Woodward]. There’s no secret that it’s a constrained site … and they have [had] to adjust days and hours of work,” she says.
Overtime, Prefab, Scheduling
Initial delays and the approaching football season put more pressure on the contractor to get the job done in a shorter time frame than initially planned. Woodward addressed the challenge by tightening its scheduling, using more overtime and incorporating some prefab design. Because the university was still receiving donations after the groundbreaking, there were a number of changes and additions during construction.
Delays in starting the project, including changes in design based on input from neighbors, raised the project cost by about $3 million, Jones says.
Because of space and time limitations, Woodward made a great effort to sequence the work as efficiently as possible. With little laydown space, crews utilized the field itself and built the stadium around it. They also left out a small section in the stadium wall to accommodate large machinery. Woodward had to synchronize scheduling work precisely with material arrivals to minimize clutter.
“We had to do a lot of up-front planning on how we were going to get those materials in and how we were going to be able to work three or four steel erection crews simultaneously,” he says.
Some parts of the stadium also tied into existing office buildings, requiring crews to work closely with the university to schedule closures. Stormwater drainage was another important issue. One of the first parts of the project entailed constructing a 60,000-cu-ft stormwater detention system just outside the stadium. All the drainage from the stadium and surrounding campus is piped into an underground holding area, then pumped into the city’s main system.
“We put in the stormwater detention system, then built the practice field on top. It helps drain not only the field but also this side of the campus,” says Flower.
At peak construction, up to 200 workers were on site. Woodward is using more than two dozen subcontractors on the project, including Durr Heavy Construction and MCC Group. Georgia-based UBU Sports is installing the field. UBU CEO Mark Nicholls says Tulane took an extraordinary amount of time reviewing the field layout and finding the right product and design. They ultimately selected the UBU Speed Series S5-M, a synthetic turf engineered with Harmony silt-film fiber and a 70% rubber/30% sand-infill ratio.
Nicholls says Woodward was instructed to provide the appropriate base and slope for the field. The area required enough drainage to handle a 100-year storm and meet certain specs for compactability and planarity. Turf installation, which started in mid-July, typically takes 21 days from start to finish, says Nicholls. The turf is manufactured at the firm’s facility in Dalton, Ga., trucked to the site, then rolled out in segments and sewn into place. The finished field will have 2.5 in. of grass-plate fiber with 1.75 in. of rubber infill.
“There is a significant amount of craftsmanship involved in building one of these fields. While many people can build a run-of-the-mill high-school field, this is a higher level,” he says.
