Building Up Ballpark Village




Ballpark Village is comprised of a 37-story mixed-use tower, which will provide housing and retail space near San Diego’s Petco Park.

Morley is using a combination of placing booms and truck-mounted concrete boom pumps to place concrete at Ballpark Village.

Nearby Petco Park, home of the San Diego Padres, can be seen in the background.

Approximately 60,000 cubic yards of concrete will be placed for the project.

Morley is utilizing two MX 34/38Z placing booms; one set up on a climbing core and the other hopscotched between three RS 750 Pin towers.

Building Up Ballpark Village

In 1996, Major League Baseball team the San Diego Padres was sharing a park with the National Football League’s San Diego Chargers—the baseball team was in desperate need of a new ballpark. JMI Realty (JMI) was appointed by the City of San Diego and the San Diego Padres to act as the Master Developer of the Ballpark District, a comprehensive plan to revitalize San Diego’s aging downtown, particularly the East Village area that would include the new park. The first phase of the project, which opened in 2004, was the Padres’ $450 million Petco Park, located across Harbor Drive from the San Diego Convention Center.

Part of the redevelopment plan for this prime downtown real estate also included a now $250 million, 634-unit residential project, 51,000 square feet of retail space, and a 37-story tower, which was first approved in 2005. However, due to varying political and economic views, the Ballpark Village Parcel C (Ballpark Village) project had been put on hold until Fall 2015. With the high-rise project finally moving forward, its general contractor, Turner Construction Company, sought out the expertise of Morley Construction Company (Morley) to place the 82,490 cubic yards (63,068m3) of concrete needed for the project using multiple pieces of Putzmeister equipment.

When JMI was originally contracted to draft a redevelopment plan for the neighborhood, it was tasked with bringing city leaders and community groups together. The final plan is a three-block development that creates a great pedestrian experience, interconnecting them and bringing in the urban core with a neighborhood feel.

Ballpark Village plays a large role in creating that welcoming, community atmosphere. The multi-family asset will offer views of the Pacific Ocean, San Diego Bay, Coronado Island and bridge, and the downtown skyline. Community amenities include a rooftop pool, clubhouse, spa, fire pit and barbecue area. The property will also feature a three-level parking garage and 24,000 square feet of retail space.

Strategic Set up
To place concrete for the massive project, Morley used several pieces of Putzmeister equipment at various locations on site. Two MX 34/38Z placing booms are being utilized; one set up on a climbing core and the other hopscotched between three RS 750 pin towers. The crew is using 36Z-Meter, 38Z-Meter, and 47Z-Meter Truck-Mounted Concrete Boom Pumps, and one BSA 14000 Trailer-Mounted Concrete Pump to pump concrete through the placing booms.

Although the jobsite is 180,000 square feet (16,723m2), only one-third of it is accessible by pumps from the street, making placing booms essential; the entire east and half of the south side of the project was supplied entirely by the booms.

“The freestanding pin tower allowed us to use placing booms early in the project,” said Jason Sperry, Concrete General Superintendent for Morley. “So early that placing booms were used to place three of the five foundation mat pours.”

The cruciform base and placing boom on top of the wall climber enables the crew to place all of the decks and vertical concrete for the tower from the single access point on the job. Several times, to pour columns, walls and decks on the north side of the project, Morley pumped to the placing booms through five-inch line (13cm) approximately 650 feet (198m) horizontally using its trailer pump.

“With significant horizontal and vertical slick line distances, we needed pumps that could perform reliably and deliver the desired volumes at a high pour rate,” said Sperry. “Putzmeister’s concrete pumps have proven to be that reliable source for our company.”

The developer’s construction manager, Tom Delaney of Springline Associates, added, “Morley has placed an enormous amount of concrete on a tight schedule and under the challenging conditions of an urban jobsite. From my perspective, Morley’s crews and equipment have performed flawlessly.”  

Busy Location
Since Ballpark Village is located right in the heart of San Diego’s downtown, vehicle and pedestrian traffic alike are extremely heavy. Without a special permit, the crew was only able to close one traffic lane at a time, causing the job site to become crowded at times. Thus, it was essential that concrete pumping equipment be compact and efficient.

Morley utilized the 38Z-Meter’s One-Sided Support (OSS) outrigger system on numerous occasions. The system allows the boom pump operator to reduce the outrigger span on the non-working side of the unit. Through a series of sensors, OSS achieves set up in confined areas without full outrigger deployment and maintains a defined working envelope, preventing the operator from positioning the boom outside of a safe operational range.

“The OSS system made it possible to fit inside a single traffic lane anytime of the day to place concrete,” said Sperry. “It was critical in helping us operate in such a confined space.”

At Last
Concrete work for Ballpark Village is anticipated for completion in mid-2017. In the works for nearly 17 years, upon opening in 2018 the development will not only facilitate a community atmosphere, but will also offer new options for living and entertaining in downtown San Diego.
