Boom Pumps in Action at Reliance Industries, Jamnagar
Jamnagar district is in the state of Gujarat. The city lies to the south of Gulf of Kutch and is 337 km west of the state capital, Gandhinagar. Recently, Jamnagar shot to prominence as Reliance Industries, India’s largest private company, established the world’s largest oil refinery near the village of Moti Khavdi in Jamnagar and the city consequently has been nicknamed as the ‘Oil City of India’.
Reliance Industries has started the Phase-3 of expansion of its petrochemical plant, called J-3. The project will take almost 3 years to complete with a total concrete pour of 24,00,000m3. At present, 20 Putzmeister boom pumps, including sixteen BSF 36.09 and four BSF 32.09, are working on the site. As and when the project accelerates, more machines will be brought in to complete the pour. Putzmeister takes great pride in being associated with India’s leading private sector corporate industry.

Putzmeister continues to provide the best innovations and quality in its concrete equipments, and the world and our global partners know that Putzmeister is the one who sets standards ‘every single time we pour’. At the same time, on the other side of the globe, Putzmeister was all set to create a new world record in Los Angeles, USA.
Putzmeister Sets New Guinness World Record
After a great successful concrete pour in India, the next day Putzmeister set a world record in Los Angeles, USA. The massive pour took place with 12 Putzmeister truck-mounted concrete boom pumps ranging from 32 to 47 Metres, two Putzmeister placing boom towers, and two Putzmeister trailer-mounted pumps. These concrete pumps were strategically placed both inside and above the excavation. Total 19 pumps were utilized for this enormous 16,200 cubic metre concrete pouring. It took 18.5 hours to complete the pour, which steered Putzmeister towards setting a new Guinness World Record for the largest continuous concrete pour on 15th February 2014 in Los Angeles.
The pour was to lay the foundation of the Wilshire Grand project, which will be the tallest structure west of the Mississippi when finished at 73 stories and 335 m in height. Turner and Conco, the general contractor of the project, devised a plan for the concrete pour, which was located 24-29 m below street level. For the past several months, crews have prepared the site by digging a 6 m deep pit and lining it with 3700 tons of reinforcing steel.
“We utilized Putzmeister equipment due to its durability and reliability,” said Michael Marchesano, Turner’s general superintendent. “With a continuous pour of this magnitude, you need to be able to count on your equipment to keep doing its job, even under demanding conditions.”
The pour included 227 ready mix trucks making more than 2,100 trips and pouring almost 39 million tons of concrete during an 18 ½-hour period.
“Each truck made 10 to 14 concrete drops, traveling through the night between eight different concrete plants within a 30 kilometre radius,” said Marchesano. “The first batch of concrete poured onto the site came from a plant in Vernon that poured the first concrete in Southern California ever.”
“We were extremely happy with how all of the Putzmeister equipment performed,” said Marchesano. “A pour this size requires extensive planning, precision, and dependable equipment. Everything went more smoothly than we could have imagined.”
The concrete pour qualified as the largest continuous concrete pour in history and officially claimed a Guinness World Record.
Given that Los Angeles is the second most populous city in the United States, the construction team anticipated logistical challenges when planning the large mat pour at the project’s downtown location. To minimize the impact on businesses and residents, they began the pour on a Saturday evening and concluded around noon the next day.

“Because the concrete must be poured within 90 minutes of being mixed, trucks had to arrive on time,” Marchesano explained. “In case of freeway jams, alternate routes were mapped.” Putzmeister Concrete Machines Pvt. Ltd.
Not only was outside traffic a concern, but job site congestion also was a challenge. Equipment had to be carefully chosen to accommodate the site’s needs.

“Through its durability and diverse selection of pumps, Putzmeister helped us overcome the challenge of having a large amount of material that needed to be poured continuously in a dense urban area,” said Marchesano. “Each piece of equipment had its role and was orchestrated to help make the pour run as smoothly and efficiently as possible.”
Building Up
Now that the foundation is in place, the crew will begin working on the attached parking structure and 73-story building that will make up the Wilshire Grand project. Both of the existing Putzmeister MX 34-4 Placing Boom Towers that were used for the concrete pour will remain in place while the crew builds up. Two additional Putzmeister placing booms will be constructed to help place concrete for the underground parking structure.
The two Putzmeister trailer pumps used on the concrete pour will also be used to pump the concrete to the placing towers. The crew will be pumping more than 60,000 m3 of concrete vertically, including lightweight concrete and C55 mixes. With such well-planned and organised preparations, Putzmeister is assertive of providing precise solutions to its clients in India.
