Beginning mid-June, two large cranes will be brought onto the construction site. The largest will be a crawler crane with an attached drill rig.
The largest crane will stand approximately 205 feet tall and be used to install the new hospital’s foundation, consisting of Auger Pressure Grouted (APG) drilled piers. Once assembled at the bottom of the excavation area, the crane will extend approximately 130 feet above the existing hospital’s helipad atop the Fainer Building.
Since drilling is being used to install the piers, rather than pile driving, the process is not expected to produce any significant noise or vibrations.
Installation of approximately ten test piers will be performed on or about June 17 through 19 and full scale installation is scheduled to begin on or about July 9 and continue through the end of August.
For a brief time during the testing program and for approximately 4-6 weeks, starting July 9, during the installation period, alternate arrangements will need to be made to accommodate emergency helicopter operations. This is necessary because the height of the crane will encroach into the helipad flight path atop the Fainer Building. During those periods, the alternate landing site, located in the upper parking lot near Foothill Road, will be used for emergency helicopter operations. The approach and departure flight path for the alternate landing site is from the southwest, over the Medical Examiner’s building.
The use of the alternate landing site will be limited to Monday through Friday from 7 AM to 7 PM. Night time and weekend landings will continue to be on the Fainer helipad. Historically, helicopter landings occur, on average, 2-3 times a week with the majority occurring on weekends.
Beginning on or about June 2, there will be construction activity on County property to further develop the temporary contractor parking and staging area in support of the Hospital Replacement Wing project.
There will be some construction related noise from earth moving equipment for the installation of drainage swales, gravel, saw-cutting for removal of concrete, striping and fence modifications. All work will be done within the Work Zone shown in the graphic below. Dust control measures, such as wetting of materials, will be implemented during all earth moving activities. No additional fill material will be delivered to the site. Additionally, office trailers will be moved into the lot for use by construction staff. Staff use of the trailers will be limited to the work day. No lights from the trailers will be visible at night.
The working hours for this construction work are between the hours of 8am and 5pm and only Monday through Friday, with no weekend work, and is expected to last for approximately three weeks.
Beginning the first week of June, two large cranes will be brought onto the construction site. One will be a large crawler crane with an attached drill rig. The second crane will be to support the drill operation.
The equipment will stand 220 feet tall and be used to install the new hospital’s foundation consisting of Auger Pressure Grouted (APG) Piles. Once assembled at the bottom of the excavation area, the crane’s boom will rise approximately 140 feet above the existing hospital’s helipad.
Because this is an auger pile drilling operation and not a pile driving one, the process will not produce any significant noise or vibrations.
Preparations will start in June, with production piles beginning in early July and continuing through the end of August.
