AZ Cardinals to Hoist Roof Assembly


Recommended Posts

Rumors have it that the Cardinals' construction crew is getting ready to hoist the entire roof assembly onto the super-columns at the stadium site. Here's how the AZ-STA website describes the process:

The Brunel trusses will be hoisted using ?strand jacks? ? special hoisting systems capable of raising tremendous weights. All four corners of the roof assembly will be raised at a synchronized rate until they are slightly above the tops of the super columns where they will rest. Then the trusses will be secured to the top of the columns with a saddle beam.

They've been building the entire roof structure in the main "floor" area of the stadium, and will be lifting the whole thing up for what we believe is sometime on Saturday (02/19/2005).

The Cardinals have had a webcam in place for a while now, so you can watch the whole thing (hopefully the camera won't go down on Saturday!):

Here are some facts about the lift - this came from RobbleRobble on the ASFN message board:

2/18/2005 - Ironworkers disconnect the trusses from their support posts on which they have been resting during construction. Support cables are disconnected and the lift team raises the roof an initial 18? to 24?. The roof assembly settles overnight.

2/19/2005 - Engineers begin the carefully controlled ascent of the roof at approximately 9 a.m. There are frequent stopping points during the day as inspection teams review the progress. The entire process may take seven to nine hours.

2/20/2005 - Ironworkers install the transfer girders in the notches at the top of the Super columns. The roof is lowered 18? to 24? coming to rest on the transfer girders.

2/21/2005 - Lift Contingency Day

March 2005 - Work begins to complete closure of the roof. The Brunel trusses support the retractable roof panels and a mix of structural steel, decking, rubberized roofing and a waterproof fabric surrounds the retractable panels.

July 2005 - Roof construction completes.

Roof Facts

- Commencing Friday, February 18, 2005, the center portion of the Arizona Cardinals Stadium roof with two retractable panels will be lifted into place.

- The roof portion being lifted covers a total of 100,000 SF with two retractable panels which when parted in the center create a 240? X 360? opening. The total lift will weigh approximately 5,500 TONS. That is 11 MILLION POUNDS or roughly the weight of 14 Boeing 747 airplanes. This is the heaviest lift of a stadium roof at one time in North America.

- The firm contracted to perform the lift is Mammoet, an international company specializing in heavy lifting and transport. The lift is accomplished with eight strand-lifting units capable of hoisting 990 tons each. The total capacity of the lifting system is 7,920 tons. These lifting units use hydraulic pressure to grip and lift cables in a maximum of 18? strokes. During each stroke, the hydraulic pressure and the position of the wedges which grip the cables are constantly monitored by computers and indicators mounted throughout the system. The roof will be lifted about 120? to a final bearing of about 156? above the stadium floor.

- The roof is set on two giant Brunel trusses, each 87? tall and 700? long. The corner of each Brunel truss is set into a channel on each of four Super Columns specifically engineered and designed to perform this lift. Each Super Column is 173? tall, 17 ½? wide and 12? deep.

Oh - and a side-note: apparently, the seats will be Cardinal Red (what else?), but the railing in the stadium will be Yellow. As in the Yellow in the new logo's beak. Furthering speculation to the rumor that Yellow will play a part as an accent color in the new uniforms.

Here's NFLMedia.com's take:


Cardinals Raise Roof on New Stadium

Footage from this weekend?s roof lift at the new Arizona Cardinals Stadium will be available via satellite this Sunday (Feb. 20) from 4:30-5:00 p.m. M.S.T. (6:30-7:00 p.m. E.S.T.).

This weekend, the 5,500-ton center portion of the roof will be lifted to the top of the stadium 156 feet above the ground in what will be the heaviest roof lift ever in North America. Raising the 11-million pound steel roof section is like lifting 14 Boeing 747 airplanes or approximately 34,000 NFL linemen. It is a three-to-four day process but the majority of lifting is scheduled for Saturday. The roof is raised via a strand-jack lifting system that has the capacity to lift the Eiffel Tower.

Construction is more than halfway completed on the stadium, which will feature a retractable roof as well as a completely retractable natural grass playing surface, the first of its kind in North America. It is on schedule to open in time for the 2006 season and will not only be the home of the Arizona Cardinals and the Fiesta Bowl but the stadium will also host the Super Bowl in February of 2008.

The feed will contain video footage from the event as well as interviews with key individuals involved. It will also include time-lapse video footage that shows the roof lift from start to finish.

The relevant information on the satellite feed is as follows:

Date: Sunday, February 20, 2005

Time: 4:30-5:00 p.m. (M.S.T) / 6:30-7:00 PM (E.S.T.)

Location: SBS-6, K2, Uplink Frequency 14049.5 Horizontal/

Downlink frequency 11749.5 Vertical

PLEASE NOTE: Inclement weather could affect the schedule for the lift and as a result, this satellite feed. If there any changes a follow-up advisory will be sent.

It looks nice, I just hope you can actually walk from place to place, much like a downtown area. If it's nothing more than an overglorified power centre where the car is the dominant mode of transportation, then I won't be impressed.

I saw picture of the roof raising, and I must say, the stadium is looking more impressive by the day. :)

I saw, I came, I left.

Is that the Glendale Arena next door?

Yes it is...and, they are building a whole entertainment/retail complex in the surrounding area around Glendale Arena. It should be really nice once it's all done.

Here's a link to the Westgate City Center:

That's if Steve Ellman or however you spell his name can get off his ass and start building it. We should of had the movie theater up and running by this summer

...and here's a new aerial shot - although this was taken last month:


just went by the new stadium on the loop 101, which is a freeway right next to the new stadium and it looks to be one of the best stadiums since the BOB
