Utah DOTâ€™s Experience with Ultra-High Performance Concrete
Sponsored by the Federal Highway Association
Carmen Swanwick P.E., Chief Structural Engineer, Utah DOT
Cheryl Hersh Simmons P.E., Structures Design Manager, Utah DOT
Eric Wells , Area Manager, Granite Construction Company
Date and Time:
Thursday, March 26, 2015 (1:00 - 2:00 pm Eastern Time)
Utah is the first state in the U.S. to make ABC a common practice. Continuing its implementation of promising ABC technologies, UDOT recently completed its first project utilizing UHPC with full-depth precast concrete deck panels on a three-span continuous steel girder bridge. UHPC was used for the closure joints, haunch, and blockouts. The presentation will provide a project overview and describe the owner and contractor perspectives as well as discuss design and construction details and lessons learned.

Recent code changes, increasing sustainability requirements, and a challenging economy are just some of the factors increasing demand for high performance structures. However, high performance is not business-as-usual. The concept of 'high performance' encompasses sustainability; however, it goes beyond a 'this-or-that' approach by requiring optimization of all relevant attributes for a project on a life cycle basis. This presentation will explain what high performance structures are, and how precast concrete can help you achieve your high performance project goals. The presentation also covers the basics of precast concrete, its applications, finishes, etc.

Middlebury College Field House, Middlebury, VT
The field house at Middlebury College in Middlebury, Vermont, incorporates a variety of flexible spaces, including an indoor practice space, competition track, expanded recreation space, and spectator accommodations. A rigorous master planning and programming effort determined the size and location of the facility, carefully considering the buildingâ€™s relationship to the existing athletic center and outdoor fields. To help achieve these goals, the designers used a variety of precast concrete components, including bleachers and spandrels.
The project included lowering the event floor 12 feet below grade to mitigate the facilityâ€™s significant height and mass, â€œcreating a complementary relationship with surrounding facilities and outdoor fields,â€� says a spokesperson for Sasaki Associates Inc. An expanded entry lobby provides a single point of access for each of the major venues housed in the sports complex. These include the new 120,000-square-foot field house, ice arena, natatorium, basketball arena, squash center, and recreation facility. A hardscape plaza and tree-lined pedestrian promenade connects the facility to the main campus.
The structure features precast concrete bleachers and stairs, along with a variety of ancillary components, including slabs, benches, base pieces, plat slabs, and benches. Precast concrete spandrels and column wraps complement the aesthetic design.
The precast concrete components were fabricated by J.P. Carrara & Sons Inc., in Middlebury, VT.
Prospect Plaza, Brooklyn, NY
A total-precast concrete structural system will help kick off a threeâ€“phase construction program for the Prospect Plaza in the Oceanhill-Brownsville community of Brooklyn. The project, owned by the New York City Housing Authority (NYCHA), is being developed under the cityâ€™s New Housing Marketplace Plan, a multibillion-dollar initiative to finance 165,000 units of affordable housing for 500,000 New Yorkers.
The structures will comprise hollowcore prestressed concrete slabs and precast concrete slabs, beams, interior and exterior wall panels, solid slabs, and stairs and landing. Many of the exterior panels will feature embedded thin brick to add visual appeal and texture.
In all, Oldcastle is producing 125,220 square feet of components. â€œOldcastle has been a reliable partner supplying high-quality products to Blue Sea Development for many years,â€� says Les Bluestone, co-owner of Blue Sea Development. â€œWe look forward to working with them on Phase 1 of the project.â€�
The precast concrete components were fabricated by Oldcastle Precast Building Systems, Albany, NY .
Rhode Island School of Design Students Visit Blakeslee Prestress
Students from the Rhode Island School of Design Precast Concrete studio visited Blakeslee Prestress on Friday March 13 to see production of precast/prestressed concrete products. The tour included an educational program by PCI Northeast executive director Rita Seradarian.
The studio will focus on the design and execution of 1:1 architectural objects using the material of precast concrete. The students will progress from research on the technical methods of fabrication, to castings in scale models typical in plaster, and full size castings with concrete. The course is lead by Brett Schneider.
Through the support of the PCI Foundation precast concrete elements and later as a location for pouring of the full scale components comprising the studentsâ€™ design projects. Additional technical workshops with students working as group will also be included to introduce general methods working with concrete and formwork hands on.

Precast Hollowcore Floors and Walls for Housing
In this program, participants will understand the basics of hollowcore plank flooring systems. Hollowcore is a
common method of building multi-family and student housing, condominiums, and many other building applications.
Fabrication and installation procedures will be discussed, along with proper detailing requirements.
Building envelope considerations for energy efficiency, including fire resistance and acoustical benefits, will
be reviewed. Several case studies will be presented. After viewing this program, participants will be able to
identify the hollowcore plank systems and explain the benefits of using hollowcore plank systems with owners and
