Methods of Construction
At Bentley Residences, that work culminated in the largest residential concrete pour in Florida and the secondlargest foundation pour in the United States. Over 36 continuous hours, approximately 20,000 cubic yards of concrete were placed using ten pumps and more than 2100 truck deliveries, supported by roughly 2400 tons of reinforcing steel.
The scale of the pour demanded precise sequencing. Concrete had to arrive continuously, crews had to rotate without interrupting the operation, and testing had to take place throughout to ensure the material met the project’ s specifications.
With a project of this scale, the foundation sets the standard for everything that follows. There is no room to improvise once the pour is underway, so the sequencing, logistics and quality controls all have to be resolved in advance.
Reaching new heights
With the foundation complete, construction has shifted into the vertical phase. As the tower rises, the structure, building systems and residential layouts must progress in a carefully managed sequence so that work on one level does not create conflicts several floors later.
Digital modeling and construction technology make that process more exact. Teams can identify clashes between structural, mechanical and architectural elements before they reach the field, reducing rework and helping the building advance more efficiently.
Going vertical is where years of design and engineering begin to take physical form. At Bentley Residences, every floor carries features that are unusual for a residential tower, so the structure has to be built around the experience being created rather than the other way around.
