Ballpark Village plays a large role in creating that welcoming, community atmosphere.

Some 82,490 yd³ (63,068 m³) of concrete was needed for the project using multiple pieces of Putzmeister equipment.

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 were utilized; one set up on a climbing core and the other hopscotched between three RS 750 pin towers.

The crew used 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 ft² (16,723 m²), 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.

Jason Sperry, Concrete General Superintendent for Morley said:

The freestanding pin tower allowed us to use placing booms early in the project. So early that placing booms were used to place three of the five foundation mat pours.

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 (13 cm) a distance of approximately 650 ft (198 m) horizontally using its trailer pump.The cruciform base and placing boom on top of the wall climber enabled the crew to place all of the decks and vertical concrete for the tower from the single access point on the job.

Busy Location

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.

Concrete work for Ballpark Village was completed mid-2017. 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.
