New San Francisco 49ers Stadium Scores Big with BioMod® Infrastructure Management System

New San Francisco 49ers Stadium Scores Big with BioMod® Infrastructure Management System

A large construction project such as a major-league sports stadium can include significant expanses of runoff-generating hardscape. A venue capable of seating nearly 70,000 people requires large parking areas and other impervious grounds. If rainwater can turn a football field into a muddy swamp, it can also turn a parking lot into a floodplain. Draining that area effectively and treating the runoff is a basic necessity that should be provided from the very beginning of the project, but it can present challenges.

The new San Francisco 49ers stadium in Santa Clara, Calif., is a good case in point. The new stadium moved the team out of Candlestick Park into a location with about double the square footage, better freeway access and about twice the parking spaces. Parking lot runoff typically includes petrochemical pollutants that drip or leak from vehicles as well as litter and other debris. The new stadium sits adjacent to San Tomas Aquino Creek, which flows into San Francisco Bay less than six miles away. The site is on land with a high water table, and existing storm-drain lines are not very far below the surface. As such, a stormwater infiltration system would not work.

Biofiltration Systems

To handle stormwater runoff from the parking lots, access roads and other hardscapes surrounding the stadium, project manager GHD Engineering selected the BioMod® biofiltration system, a stormwater collection and natural treatment system manufactured by industry leader Oldcastle® Precast. Today, the stadium has six biofiltration systems to naturally treat and manage stormwater runoff from the parking lots and grounds immediately adjoining the site.

In total, about 2,500 linear feet of BioMod cells, or approximately 14,000 square feet of bioretention area, currently treat stormwater runoff from the complex. Although the standard bioretention modules used in most of the 49ers project are three feet wide, two systems in the second phase featured tapered plans: one three feet wide at one end and 14 feet at the other, an irregular wedge more than 300 feet long. The other is 230 feet long and rectangular over most of its length, with a subtle taper at the south end. The unusual shapes were designed by the architect with specific visual goals in mind.

The main parking lot has two biofiltration systems. The one on the north side featuring the rounded modules was manufactured and installed first. The main run is nearly three feet wide and just more than 600 feet long, mostly basic curb-cut units without pre-filtration. The modules that lie perpendicular to the main run are seven feet wide. They divide the parking lot into six Drainage Management Areas (DMAs), each about 100 feet long for managing about 10,000 square feet of surface runoff.

Containing Runoff

Water is one of nature’s most powerful forces. Hardscaping can turn that force destructive, both in terms of erosion and pollution. A properly designed stormwater management system has three essential functions:

1. Remove rainwater from the hardscape and other impervious surfaces.
2. Channel runoff so it does not erode the surrounding landscape.
3. Treat runoff so it does not pollute the landscape or downstream waters.

Biofiltration is one of the simplest, most natural and cost-effective ways to collect runoff and treat it onsite, and it’s considered a best practice under U.S. Environmental Protection Agency (EPA) guidelines for Low-Impact Development (LID).

During storm events, rainwater runs into the modules and ponds and then slowly percolates into the media where it’s naturally filtered along the way. The treated water is collected in a perforated pipe that runs along the bottom of the biofiltration system and ultimately links into the storm drain system.

Filtered pollutants are naturally broken down by microbes, providing nutrients for the plants that are irrigated by the rainwater. In locations where rainfall may not be frequent or consistent enough to sustain them, such as the new 49ers stadium, integral drip lines can be built into the modules to deliver supplemental irrigation.

BioMod systems can include basic units with small ornamental plantings, tree modules, pre-filtration units, light-pole modules and custom designs. Pre-filtration modules have an upper chamber designed to collect litter and other solid debris, and detain it so it does not interfere with drainage. Pre-filtration units must be periodically cleaned to dispose of the collected debris.

Overflow drains can be added to handle extremely heavy rains. During unusually high flows, when the ponding depth can’t be drained fast enough through the filtration media to keep up with the rainfall, excess water is diverted into the overflow drains and then into the storm-drain system. The stadium system was designed to handle a 10-year rain event. Having an integrated overflow bypass built into the biofiltration system eliminates the need to design and install a separate peak conveyance system, as is often necessary with other biofiltration setups.

Custom Solutions

The drainage rate is determined by the surface area of the bioretention system and by the composition of the filtration media. The BioMod system doesn’t require proprietary biofiltration media. For the 49ers stadium, engineers selected a blend that yields up to 10 inches per hour of drainage in accordance with Contra Costa County requirements. Other media blends are capable of treating as much as 100 inches of rainwater per hour, as needed. Computed against the size of the impervious hardscape and the predicted rainfall, the size of the required bioretention system can quickly be calculated. However, the media must be selected not only for drainage characteristics, but also for compatibility with the intended plantings.

One of the greatest advantages of a biofiltration system is that it’s easy to maintain and essentially self-sustaining. It harnesses nature to break down petrochemical pollutants, a process that needs little help from humans. Debris must be occasionally removed from the system, and plants must be maintained like any other landscaping, but little more is necessary. The San Francisco 49ers biofiltration system will largely maintain itself, keeping the grounds looking good and safe from flooding, while protecting the San Francisco Bay and other sensitive areas surrounding it from stormwater pollutants.

Oldcastle Infrastructure Mansfield Participates in Longhorn Boy Scouts of America Fundraiser

Oldcastle Infrastructure Mansfield Participates in Longhorn Boy Scouts of America Fundraiser

On May 18th, members of Oldcastle Infrastructure’s Mansfield, Texas facility participated in a sporting clays competition fundraiser, benefiting the Longhorn Council, Boy Scouts of America, based in Fort Worth, Texas.

The event was hosted by Oncor Electric Delivery, along with Delta Oil & Gas and Hillwood Properties at the Alpine Shooting Range in Ft. Worth, Texas.    Oldcastle Infrastructure Sales Manager Tina Eaton organized two teams comprised of our core customers who install Oldcastle Infrastructure structures for Oncor Electric Delivery, a long valued customer of Oldcastle Infrastructure. The two teams consisted of members from John Burns Construction Company, Larrett Inc., Mission Site Services and WillBros T&D Services.

More than 250 people from the Dallas/Ft. Worth metroplex area participated in the team‐based sporting clays competition.  Sporting clays is the closest thing to real field shooting of all shotgun sports. Rather than having clay birds thrown from standardized distances and angles as with skeet or trap, sporting clays courses are designed to simulate the hunting of ducks, pheasants, other upland birds, and even rabbits.

Furthermore, special guest Ft. Worth City Mayor Betsy Price, ready and willing, anchored a team and provided the keynote speech at the luncheon.

The event was an overwhelming success, raising more than $170,000 for the Boy Scouts of America Scoutreach program which focuses on character development for at‐risk youth in the inner city.

“The event was an enormous opportunity to make a difference in the lives of the youth within our community.  We are honored to join with our business partners to provide essential support for the Longhorn Council Scoutreach program.” said Tina Eaton, Oldcastle Infrastructure Sales Manager.

Jim Greer, Chief Operating Officer for Oncor Electric Delivery applauded the efforts of everyone attending and thanked every participant and sponsor for their support of the program.

FOLSOM, N.J. (June 6, 2017)

Large RCP Pipe Used to Reconstruct StormWater Outfalls for Post‐Hurricane Sandy Resiliency Project in New Jersey

Large RCP Pipe Used to Reconstruct StormWater Outfalls for Post‐Hurricane Sandy Resiliency Project in New Jersey

As part of the Christie Administration’s post‐ Hurricane Sandy storm resiliency effort and part of the Sandy Hook to Barnegat Inlet Beach Erosion Control Project, Oldcastle Infrastructure was contracted to supply 2,704 feet of reinforced concrete pipe (RCP) to extend several stormwater out‐falls into the ocean in the area of Loch Arbour and Deal in Monmouth County, NJ.

The overall project, pumping 1.4 million cubic yards of sand on 1.6 miles of beach in Elberon and Deal, as well as the modification to six existing stormwater outfalls and two existing groins, coastal protection structures extending from the beach into the ocean, is part of the Christie Administration’s comprehensive resiliency plan to reduce risk from storm damage on the New Jersey shore. In the aftermath of Hurricane Sandy, these coastal protection structures will provide additional beach erosion control and storm risk reduction to this coastal area.

Overall, the Christie Administration, in partnership with the U.S. Army Corps of Engineers, awarded a contract of approximately $90 million to Manson Construction Company of Seattle, WA to reconstruct beaches, storm water outfalls and implement modifications to existing groins at Loch Arbour and Deal, NJ.

As a portion of the project, Agate Construction of Oceanview, NJ was subcontracted to install extensions to the stormwater outfalls, who in turn contracted Oldcastle Infrastructure Folsom, N.J. to design and manufacture 584 feet of 58‐inch x 91‐inch HE 3 (Horizontal Elliptical‐Class 3) reinforced concrete pipe (RCP); 592 feet of 63‐inch x 98‐inch HE3 RCP; and 1,528 feet of 96‐inch diameter O‐ring gasketed RCP. Outfall 19 was designed to accommodate the 63‐inch x 98‐inch HE3 RCP. Outfall 34 was designed for the 58‐inch x 91‐inch HE3, and outfall 36 was designed for the 96‐inch diameter RCP.

Due to the marine environment, the RCP was designed to be produced with a special concrete mix and reinforced with galvanized reinforcing wire to resist corrosion.

“Working with the galvanized reinforced wire posed new challenges for the facility, but the team was successful at accomplishing this endeavor,” said Nike Domenico, Sales Manager for the Oldcastle Infrastructure Mid‐Atlantic Pipe Group.

Additionally, several RCP pipe units were produced as special length or skewed end pieces, so that the joints would lay precisely upon a saddle‐supporting system connected to 45‐foot piles driven to a depth of 40 feet. The saddle‐ supporting system was installed preceding the pipe installation.

The out‐falls, a place where the stormwater drains or discharges, generated several challenges that had to be addressed. Primarily, marine weather conditions; high waves and wind affecting the installation of the piles and work area conditions due to high tide/low tide in the work zone; constant maintenance and dewatering of the cofferdams; precision placement of the RCP pipe; and special/custom pieces of pipe manufactured to retain straps and pipe joints to center over the centerline of pile caps. In addition, Outfalls 19, 34 and 36 supplied by Oldcastle Infrastructure were under construction simultaneously.

Operations Manager for Oldcastle Infrastructure Mid‐Atlantic Pipe Group George Hand II remarked, “Using Reinforced Concrete Pipe on the project was a great selection of materials for this type of application and selecting Oldcastle Infrastructure proved to be advantageous.  The project would need custom pieces sporadically throughout the project and that is our forte.  The quality RCP pipe we supplied met all specifications and the fast turnaround time reflected our commitment to the project.  The entire project was a victory from the beginning.   Having the right people in the right place in our organization allowed us to make this project a success.  It was a great accomplishment for the team and the organization.”

The restoration and repair work is funded 100 percent through the Army Corps’ Flood Control and Coastal Emergencies program. Construction is funded entirely by the federal government through the 2013 Disaster Relief Appropriations Act (PL113‐2), commonly known as the Hurricane Sandy Relief Bill. Following the completion of initial construction, the project is eligible for continued periodic nourishment.
