PROJECT UPDATE 🚨🏗️👷🏼
Penn Presbyterian Medical Center Proton Therapy Center, Philadelphia.
Two short months ago we were just getting out of the ground. Since then, our team has been gettin’ at it! We’re at the halfway point of the proton vault, with nine of seventeen vault pours formed, poured, and stripped.
Approximately 150 feet away on the other side of the site, our second crew is hard at work on the underground tunnel that will link to the existing building. Due to tight site access, the tunnel is sheeted on both sides. We are shotcreting the tunnel walls, that vary in height from 12 to 19 feet, directly against the sheeting. Shotcrete has eliminated almost all the wall formwork - eliminating the need for a crane, formwork material, and wall ties (which would have to pe*****te the waterproofing), and reducing the number of construction joints. All these factors, along with shortening the duration of the tunnel walls, have resulted in cost and schedule savings for the project!
We here at Madison are thankful for our hard-working men and women that grind it out onsite every day, along with a top-notch team of subcontractors and suppliers!
