Designing High Performance Transportation Structures with Precast

Risk

September 23 and 25

Description: The concept of ‘high-performance’ encompasses sustainability, and goes beyond a single criteria approach by requiring optimization of all relevant attributes for a project on a life cycle basis.

This presentation will introduce how high performance is being applied to special purpose and routine highway structures in the transportation industry. It will provide an overview of how precast/prestressed concrete is being used to meet long lasting, low maintenance, accelerated constructed and low cost requirements for bridges and pavements. The presenter will briefly discuss where engineers can learn more about the basic concepts and detailed methodologies related to design and preservation of these ever changing transportation facilities. It will also introduce some of the newest innovative systems and designs being used throughout the United States for simple and complex structures.

Learning Objectives:

  • Define what high performance concrete transportation structures are.
  • Discuss the advantages and long-term benefits of high performance design as they relate to concrete transportation structures.
  • Describe how precast concrete contributes to design versatility, efficiency, and long-term performance of transportation structures.
  • Discuss some of the newest technologies in the transportation industry.

AvalonBay Apartments, Boston, MA

AvalonBay Apartments, Boston, MA

Designers on the 29-story high-rise residential building being developed at 45 Stuart Street in Boston’s theater district want to give the L-shaped complex a classic appearance that complements existing, smaller buildings on the street while emphasizing its dramatic height in line with other tall buildings nearby. To that end, they specified precast concrete architectural panels, many erected in a vertical fashion on upper floors, with tall, three-story windows punched out.

Precast concrete panels also clad the parking structure at the base, which will provide space for 198 cars. The 384,000-square-foot project wraps around existing buildings on the site, fitting in with smaller buildings on one street and taller structures on the others. The project, owned by AvalonBay Communities, is being designed by Childs Bertman Tseckares Inc., with John Moriarty & Associates serving as construction manager.

The precast concrete components were fabricated by Strescon Ltd.

MBTA Salem Station Parking Structure, Salem, MA

MBTA Salem Station Parking Structure, Salem, MA

To provide a cost-efficient structure that could be built quickly and fit into the neighborhood’s architectural style, designers specified a total-precast concrete structure for the new five-story, 690-car parking structure at the MBTA train station in Salem, Massachusetts.

“Besides using precast because of its added value economically and in construction-time reduction, we also saw its value as a durable system that could blend in with the surrounding historic buildings in Salem,� explains Deborah Fennick, principal at Fennick McCredie Architecture, the architectural firm on the project.

The precast concrete components were fabricated by Unistress Corp.

Avalon at Assembly Row Parking Structures, Somerville, MA

Avalon at Assembly Row Parking Structures, Somerville, MA

Designers for the new mixed-use facilities at Avalon at Assembly Row in Somerville, Massachusetts, needed to ensure parking amenities were in place when the adjacent mixed-use buildings were complete. To achieve this, they created two total-precast concrete parking structures that connect to the mixed-use properties via expansion joints. The poor soil conditions in the area created additional challenges due to the weight of the multi-story precast parking structures and the heavy crane required to erect the structures.

The parking structures, consisting of a five-story, 110,472-square-foot facility and a six-story, 126,649-square foot building, were designed as total precast concrete structures consisting of double tees, columns, beams, and spandrels, with shear walls, litewalls and stairways providing lateral stability. The spandrels were finished with embedded thin brick to complement the mixed-use buildings.

The precast concrete components were fabricated by Unistress Corp.

Sand Hill Bridge, Middlebury, VT

Sand Hill Bridge, Middlebury, VT

Designers of the new Sand Hill Bridge in Middlebury, Vermont, needed to create an arched design to replicate the look of the original 1924 design to meet the desires of local historical groups and town officials. But the new bridge’s configuration wouldn’t create the proper arch shape. To resolve this challenge, designers used a total-precast concrete design featuring NEXT (New England Extreme Tee) beams that span above a precast concrete arch that supports only its own dead load.

The arch was created from 12 precast concrete components that were set onto cast-in-place concrete footings on the gorge walls. Precast concrete footings, abutment walls, wing walls, approach slabs, fascia panels and four NEXT D beams were then used to construct the bridge.

The precast components were manufactured by J.P. Carrara & Sons, Inc.

Padelford Street Bridge, Berkley, MA

Padelford Street Bridge, Berkley, MA

Citizens in Berkley, Massachusetts, couldn’t abide a two-year closure for the replacement of the Padelford Street Bridge, a key overpass. To alleviate that impact, the Massachusetts Department of Transportation reviewed its plan and decided to find an accelerated bridge construction (ABC) solution. The solution resulted from a base technical concept that proposed using prefabricated/precast concrete elements as much as possible. MassDOT also used performance-based specifications with a design-build delivery method as part of the objective to limit the bridge closure to six weeks. The result is a new bridge that features 46 precast concrete substructure units.

The most challenging aspect was setting and connecting the center pier, which was designed with a continuous footing in three sections, each connected with a closure pour. “Aligning all the pieces was a key issue, so tolerances were absolutely critical,� he says. The advance work paid off. “Once the precast components arrived at the site, they were 90% ready to be put in place immediately,� explains Andy Benkert, project engineer at design firm WSP Group.

The precast components were manufactured by The Fort Miller Company, Inc.

FEATURED LEARN AT LUNCH PRESENTATION

Precast Hollowcore Floors and Walls for Housing

Lunch & Learn-Hollowcore

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 other designers.
