Donald Trump’s inaugural Las Vegas construction project will match his larger than life image. Climbing past other hotels and casinos in Las Vegas for a completion height of 620 feet, Trump International Hotel & Tower— Tower 1, will be the tallest inhabitable concrete structure in Nevada.

Ready-mix trucks deliver an average of 1300 cubic yards of concrete to the trailer pump for each floor.

First announced in 2002 and started in August 2005, the luxury residential hotel and condominium tower is modeled after the Trump International Hotel & Tower on New York City’s Columbus Circle. The height of the Las Vegas project inspired the general contractor, Perini Building Co., to explore new ways of placing concrete. Perini typically uses buckets for the majority of a project, says project manager Tony Meyer. “Hauling buckets up 620 feet the way we usually do would not allow us to work as efficiently as we needed to get the job done on time.”

Perini found the ideal solution was to use a placing boom and they hired Quinn Concrete Pumping to do the job. The decision to subcontract the concrete placement was new for Perini, which has always handled its own concrete placement. Switching to the placing boom freed up the cranes to complete other tasks.

Quinn provided a Putzmeister MXR 34/38Z Series II Detach Boom and a Putzmeister BSA 14000 Trailer Pump. The high pressure and output trailer pump was able to provide maximum volume at the greatest distances. Quinn’s operations manager, Steve Heimark, says the trailer pump remains in one spot for the entirety of the job, on the ground at the base of the site, about 50 yards from the structure, allowing easy access for the ready-mix trucks.

Slickline then carries concrete up through the elevator core to a base tower and the placing boom. Since the floors of the Trump Las Vegas are too large to pour from a single location, Quinn has mounted two towers for the placing boom, one on each side of the structure. When the crew needs to pour on the other side of the structure, a crane flies the boom and its pedestal from one tower to the other for a quick pin-connect. “The ability for us to connect the boom simply with pins as opposed to bolts not only makes the transfer process faster, it helps us improve safety,” says Heimark. “We can easily move the boom and be ready to pump again in about 15 minutes.”

Perini’s crew uses the placing boom to pour one floor per week, beginning just after midnight on Thursday and continuing until Thursday afternoon, with completion of the vertical element pours on Friday.

“We are pumping Nevada’s notoriously harsh mix specified for this project” says Heimark. “This mix is very abrasive, with very coarse aggregates and manufactured sand, which makes it a very tough mix to pump. We’ve pumped a total of 42,000 cubic yards of concrete so far—1300 cubic yards for each floor.” So far the pumping has gone smoothly.

Pours for the deck and half of the vertical elements of the structure begin every Wednesday at midnight and are completed on Thursday afternoon. The crew then comes back to the jobsite to complete the remaining half of the vertical elements on Friday. Once a pour is complete, preparation for the next floor begins. Two levels of deck forms are being used on the project to allow for the necessary rotation of formwork.

When complete, Trump International Hotel & Tower—Tower 1 will have 64 floors. To date, Quinn has placed concrete up to the 45th floor. “The project will take another six months to complete,” notes Perini’s project superintendent, Guy Shuman. “The goal is to pour one floor each week. The workers have a great rhythm going. It’s not very often that you have a chance to work on the tallest concrete building in the state.”

Prices for the condos at the Trump International Hotel & Tower Las Vegas will range from the $700,000 to $7 million. And Trump-Ruffin, LLC, the building’s owner, will not be checking out of Las Vegas anytime soon. The Trump International Hotel & Tower—Tower 2 was announced in January 2005 and will be identical to the first tower. The start and completion dates for Tower 2 are not yet determined.
