What are the concerns with the hydraulic option? (Option C)

2017-09-15T13:57:07-05:00

We know that it is feasible to create a hydraulic solution that has a single point failure system or in other words, has redundancies that prevent the lifting system from failing.  The hydraulics solution requires more engineering studies to resolve these details, especially at the connection between the lower and upper decks as they will [...]

How do you prevent the trusses from failing, if hit by debris, and if they are perpendicular to the floodwater? (Option C)

The current of the Fox River in this location does not move quickly, but moving debris is a significant concern. Debris containment on the outside of the pit walls is being studied. Additionally, the trusses will have to be braced in the other direction.

How about a floodwall or other barrier systems?

2017-09-14T10:11:10-05:00

Many different systems were evaluated. A barrier dam solution needs vertical elements (visual disturbance) or they could be hydraulically lifted, but it is difficult to create a water-tight seal. Also, the pressure of holding back water above three feet becomes difficult. Even if barriers are erected around the house, once the water rises above 4-5 [...]

Is the glass susceptible to damage during the lifting process? (Option C)

2017-09-14T10:11:10-05:00

The unified jacking system synchronizes equal pressure across the structure during the extend/retract process to prevent damage to the glass regardless of differential loads. This system would be employed for the house lifting and the hydraulic lift option. The lift cycle for the hydraulic system is designed to elevate the building less than 1” per [...]
