Scope of Work

The project scope of work entailed lowering the field by 3 feet, installing a new drainage system and irrigation system, replacing the field heating system and installing a new synthetic-covered concrete running track around the perimeter of the field. The field was re-sodded with a Bluegrass blend, and then reinforced with synthetic fibers installed by DD GrassMaster.

Lambeau Field

Location: Green Bay, Wisconsin

Owner: Green Bay Packers, Inc.

Landscape Architect: D.A. Hogan

Completed: June 2007


The project had significant challenges, first of which was building a field with very critical tolerances in the middle of a Wisconsin winter. When we were chosen to perform the total reconstruction of Lambeau Field, our team had to overcome more than the sub-zero Wisconsin winter to reconstruct a whole new field while preserving the historic stadium. The ONLY access to the field was through a tunnel, which traveled through heated space and was adjacent to meetings rooms used daily by the team and outside visitors. This made it necessary to find an alternative plan for export and import of all material needed for the construction. It was decided that the best way to complete the construction was to engineer and build a conveyor system that could handle most of the material. The conveyor moved material back and forth through the stands inside an entry portal and the vomitory, and delivered it to the parking lot where it was either trucked offsite or loaded for the trip inside the stadium.

 

On both the north and south ends of the stadium, there was an existing hump in the field against the stadium wall. These humps were left during past stadium renovations. Rather than lowering them during previous renovations, former renovations maintained the existing conditions.

 

It was decided in this renovation to remove the humps and lower the visiting team’s tunnel by 32 inches. After exposing the conditions on each end, it was determined that the stadium wall needed to be underpinned and reinforced to ensure no lateral movement from the existing structure. A new footing was poured and the wall was stabilized with reinforced 4000-PSI concrete.

 

The excavation and export of the field included 17,000 cubic yards of soil. The demolition included 18,000 square feet of 4-inch-thick concrete, 200,000 linear feet of Pex tubing that heated the field and 2,000 feet of HDPE pipe.

 

It was also discovered that drain systems still existed from two previous renovations and over 15,000 linear feet of corrugated plastic and aluminum pipe was removed. The import material included 5,000 cubic yards of specially blended sand/peat rootzone material, 10,000 tons of various crushed drainage and base stone, and 400 cubic yards of concrete for the track surrounding the field.

 

The hydronic heating system installation included a new HDPE supply and return lines. Pex Type A tubing was included on the field, along the trench drain, in the concrete track, in the visiting player’s tunnel and along the stadium wall to keep the footings free from frost. New high-efficiency boilers were installed to replace the 10-year-old boilers, as well as new pumps to replace the old pumps.

 

The system was designed to keep the field at 55°F on a day when the ambient temperature is 0°F with a 15-mile-per-hour wind. The entire system is monitored with temperature sensors in the field and concrete track. They are tied to a central control system where the stadium maintenance team can make adjustments as necessary.

 

The next component of the construction included installing the irrigation system. The system uses Hunter heads and valves. The system also required a booster pump. The final elements in the construction included painting the stadium wall, installing 1,200 linear feet of 12-inch-wide fiberglass trench drain with ADA-compliant grates, installing 200 feet of 12-inch cable tray with solid tops, and constructing the concrete track encircling the field complete with a 13MM Mondo synthetic surface. We installed Rootzone Mix 12 inches deep and laid a Kentucky Bluegrass blend sod to complete the field.

 

The new Lambeau Field was completed in July 2007. The Packers went all the way to the playoffs during the next season. Coincidence? We don’t think so.
