The makers of this video have called it “Bucket Cam,” to acknowledge the sophisticated technology utilized for the filming. (Some of us here at Annenberg Public Policy Center have given it another name: Boys and their Toys.)

With erection of the main building steel nearly complete, it’s almost time to say goodbye to the big crane – and with it the ironworkers. But not before a few final touches. Next crew to arrive will be the concrete workers. Still to come: the topping-off ceremony for the new building, set for later this month.

Ironworkers are wasting no time in assembling the skeleton of the new Annenberg Public Policy Center building. The steel beams are rising quickly above the concrete foundation and the silhouette of the building is now taking shape amid the Penn campus skyline.

For further updates on the building, as well as photo galleries documenting the progress of construction, please visit the APPC Building blog.

It takes brawn and brains (and a little ingenuity) to construct a $41.5-million building in the midst of Penn's urban campus. Need to move this truck? No problem.

Excavation for the new APPC building has been completed and the final pier poured to support the original footings of the existing Annenberg School for Communication on the west side of the construction site. Work on the outer foundation walls is proceeding and internal support columns are being installed.

By early next year, the steel beams framing the new Annenberg Public Policy Center building will begin to rise along the 36th Street walk on the University of Pennsylvania campus. Occupancy of the building, designed by noted Tokyo architect Fumihiko Maki, is now set for late summer 2009.

The building is a gift of the Annenberg Foundation and the Annenberg Foundation Trust at Sunnylands, which have contributed a total of $41.5 million to the project, including $6 million earmarked for perpetual maintenance.

But before the innovative four-story glass and wood structure takes shape above ground, a complex underground construction project is required. When completed later this summer, infrastructure improvements – undertaken to coincide with the APPC construction – will ultimately service the new building plus13 adjacent structures on campus. Upgrades of electrical and telecommunications systems as well as gas and cooling supply lines will be made. Steam lines were improved last year.

This summer the 36^th Street walkway between Walnut Street and Locust Walk will be closed and a boardwalk erected to route pedestrians away from the building site, occupied by the former Hillel House at 202 S. 36^th Street, which will be demolished. The boardwalk will remain in place for about two years.

What passersby will see initially will be a large trench that will contain two newred concrete duct banks and a gas line. The duct banks will carry power and telecommunications lines. A separate line for chiller water will be laid from Steinberg-Dietrich Hall. The Annenberg Public Policy Center basement will house a 13,200-volt transformer and circuitry that will step down power for the new building and the 13 nearby buildings. That power is coming via underground lines from the substation next to Pottruck, two blocks away on Walnut Street.

Although the logistics are complicated, the infrastructure update is simplified by one fact: “I only had to dig one hole,” said Mike Swiszcz of Penn’s Facilities and Real Estate Services, who is overseeing the APPC project. But it will be a long one.

Because the cost of underground construction is high – especially in an old and densely built location like the Penn campus, one excavation is a real cost-saver. (The cost of the project will be spread among all the beneficiaries.)

The location itself may generate some surprises.

“Who knows what we’ll hit underground,” said Swiszcz, sitting in front of a detailed blueprint of above-ground landmarks and underground utilities. “There’s a subway down there. We know exactly where that is,” he said smiling. He’s not sure what he’ll find along Locust Walk, however. Most of it is underlain with trolley tracks paved over when it became a pedestrian avenue through campus.

The project will require crossing Walnut Street at 36^th. “Walnut is a nasty crossing,” said Swiszcz. The excavation will be very deep and will have to avoid a tangle of utilities already in place.

Swiszcz wants to mount a camera directed toward the new APPC building to record its progress by snapping a picture every three minutes over the course of construction. By September, Hillel House will be down; in October, a foundation will be underway; by December, the footings poured, and at the start of 2008, steel beams begin pointing skyward.
