Central Mass. Dauphinais Large-scale poured concrete at UMass Chan medical school


WORCESTER – A concrete pour for the foundation of a new building at UMass Chan Medical School on Saturday will be one of the largest pourings in the history of a family-owned concrete company in central Massachusetts.

Dauphinais Concrete, Inc. has been pouring concrete in central Massachusetts since 1937.

Chris Dauphinais, president of the Sutton company, said the company has played a key role in several Worcester projects throughout its history.

“We have been very involved in the construction of much of the city of Worcester, whether it is Interstate 290 through town, the Centrum (now the DCU Center) – all of the skyscrapers that are currently in the city, ”said Dauphinais.

Dauphinais Béton was sold by the family in 1987, and the family bought the business in 2008. The business is currently run by the fourth generation of the Dauphinais family.

On Saturday, Dauphinais Concrete will pour one of two large concrete placements at UMass Chan Medical School. The throw will be 2,500 yards per field goal, Dauphinais said.

“For the city of Worcester it’s huge. Outside of Worcester, in Boston and so on, it’s not uncommon,” said Dauphinais. “For this time in the city of Worcester, this is a very large concrete placement.”

The pouring will be the largest Dauphinais Concrete has done since at least the 1940s and 1950s, when the team poured for the town’s Wyman-Gordon building. Dauphinais said he did not have the documentation to compare the size of the two projects.

State-of-the-art building

The casting will lay the foundation for the 350,000-square-foot medical school’s nine-story research and education building that will accelerate the search for new therapies for some of the most difficult diseases facing people. humans. The building will also include a geothermal heating and cooling system to reduce greenhouse gas emissions.

The $ 325 million building will be located between the Lazare Research Building and the Albert Sherman Center. It will include program space for 77 planned principal investigators, in addition to animal medicine and an FDA-compliant manufacturing facility for clinical therapeutic trials.

Josiah Herbert of Shawmut Design and Construction of Boston is the construction manager for the project.

Herbert, a native of Uxbridge, said the foundation for the building must be designed to reflect that 15 feet below the construction site is water.

The team had to dig about 30 to 40 feet to reach the bottom of the excavation to build the lower foundation, which means the site will be in the water table by about 15 feet. Herbert said the team needed to build an underground device to prevent water from entering the building and a waterproof membrane on top of the boat.

The building will rest on a 4-foot-thick concrete slab that will support its weight, Herbert said.

The foundation cannot use more traditional footings and columns as a support because water could penetrate them.

Lots of concrete

The pouring will consist of 250 loads of concrete serving three concrete pumps at three concrete batching plants with around 55 trucks delivering the concrete, Dauphinais said.

The trucks will come from Dauphinais Béton’s main plant on Lackey Dam Road in Douglas, as well as three other companies to meet the needs. He added that the casting is expected to last eight hours.

“In the first six hours of pouring, it will be non-stop. As fast as you can get a truck through a concrete pump, they will empty the truck and drive off and recharge,” said Dauphinais. Chris Dauphinais, president of the Sutton company

Putting the pieces together for the installment can be a bit nerve-racking, Dauphinais said.

“We’re excited. It’s a challenge, but it’s a challenge we anticipate,” said Dauphinais. “There is a lot of planning to do. You need to have a good flow of raw materials entering factories at specific times to meet the work schedule and have all mixer jobs lined up. ”

In order to prepare, Dauphinais said his company was working on aligning equipment, drivers and trucks. Portland cement has been more difficult to come by with supply shortages and freight transportation issues.

According to the Worcester Building Inspection Office, UMass Chan Medical School is a state-run entity and foundation inspections are the responsibility of state inspectors.

The Bureau of Public Security and State Inspections did not return a request for comment on the regulation of the project.
