General Building Projects
Controlling settlement and ensuring proper floor performance for any structure
Henley on the Hudson
The Roseland Property Company planned to build multi-million dollar waterfront condominiums, penthouses and townhouses along the banks of the Hudson River as a part of an urban redevelopment project- but first they had to improve some very poor soil conditions.
The soil profile consisted of an upper fill layer with large obstructions overlaying a very soft organic clay layer and a dense sand bearing layer. The initial ground improvement solution consisted of driven steel piles with large pile-caps along with pile-supported structural concrete relieving platforms and overlapping fill.
Menard’s ground improvement solutions can meet demanding schedules and strict budgets.
Menard proposed a design-build alternative that would save both time and money. With Controlled Modulus Column (CMC) rigid inclusions in mind, special load tests were conducted to calibrate and verify the finite-element modeling assumptions. The actual installation of the CMC rigid inclusions was done at approximately 92 feet—the deepest in the world at this time.

“This was a challenging project in terms of both technical complexity and field equipment demands. The compressibility of the soft soil coupled with the high building loads resulted in the need for extensive, detailed design efforts. A fun fact about this site—after being attacked by a flock of geese, Captain “Sully” Sullenberger safely landed US Airways Flight 1549 in the middle of the Hudson River approximately 300 yards from the jobsite!”
