The PTI Awards Program is intended to recognize excellence in post-tensioning applications. Any structure that has been construct-
ed or rehabilitated in the last 5 years which utilizes post-tensioning as a structural component is eligible. Entries may be submitted
by the owner, architect, engineer, contractor, or post-tensioning supplier. Entries may also be submitted by students in a new cate-
gory. The student submissions must be a structure built by a student or group of students. Built projects must incorporate post-ten-
sioning strands that prestress a building component, and may be in the form of a sculpture or other scale model.
Winners were selected by a jury of distinguished professionals and were judged based on creativity, innovation, ingenuity, cost effec-
tiveness,functionality, constructability and aesthetics. The 2008 Jury included:

4. The New Guthrie Theater Center
Project of the Year / Award of Excellence: Buildings - Mixed Use
Location: Minneapolis, Minnesota
Submitted by: AMSYSCO, Inc.
Owner: The Guthrie Theater
Architect(s): Jean Nouvel, Paris France; Architectural Alliance,
Minneapolis, Minnesota
Engineer(s): Erickson Roed & Associates
Contractor: McGough Construction Company
P/T Supplier: AMSYSCO, Inc.
Overview:
The New Guthrie Theater Center is a 250,000-square-foot performing
arts complex situated on the banks of the Mississippi River in downtown
Minneapolis, Minnesota. The $125-million development includes three
theaters: a thrust-stage theater with 1,100 seats, a 700-seat proscenium stage theater and a black-box studio featuring flexible seating.
A 178-foot, cantilevered bridge to the Mississippi River is open to visitors during box office hours. Illuminated panels, visible at night,
cover the building’s exteriors and display large mural photographs of past plays. The theater also has facilities for national productions,
large common areas, studios, classrooms, administrative offices, and a 1,000-space parking garage. French architect Jean Nouvel, in
local partnership with Architectural Alliance of Minneapolis, designed the project.
Early in the planning phases, the structural engineer and contractor determined that a post-tensioned concrete framing system would
provide the most effective solution for the main theater and parking structure. The framing system for the main theater consists of an
eight-inch-thick sloping slab supported by a radial/circular network of beams and cantilevered girders on five tiers. This unusual design
required a high degree of technical expertise in post-tensioning to accommodate the heavy live loads and large, column-free areas. For
the traditional six-level parking structure, the post-tensioning firm designed and supplied an encapsulated post-tensioning system to pro-
vide maximum corrosion protection and longevity. According to the post-tensioning supplier, the Guthrie Theater is a unique application
of post-tensioning and a good example of its ability to solve complex structural problems. The construction company chose the post-ten-
sioning supplier based on referrals citing the company’s technical strength and reliability and was pleased with the outcome.
Jury Comment: “Exceptional integration of striking architectural design with structural innovation. Unique appli-
cation of post-tensioning and a good example of its ability to solve complex structural problems.”
