Bridgeport Hospital Parking Garage, Bridgeport, CT
Officials at Bridgeport Hospital in Bridgeport, CT, knew they had to address parking issues before they
could address other needs for a new hospital facility they planned to build. The new building would need
space for employeesâ€™ and visitorsâ€™ cars while eliminating some of the available spaces by being built on
the site. To alleviate these concerns, designers created a four-story, 150,000-square-foot total-precast
concrete structure that was erected quickly before construction on the main building began.
â€œWe built the garage first, because the new facility was going to consume part of the available parking while
requiring more spaces itself,â€� explains Dave Carlson, project engineer at Spiegel Zamecnik & Shaw, the structural
engineer on the project. â€œUsing a total-precast concrete structure is a natural in our environment in the Northeast.
Itâ€™s cost-effective and offers good durability and longevity.â€�
Blakeslee Prestress Inc. fabricated and erected the components, providing design-assist services during the project.
â€œThe project team was familiar with precast concrete, and we brought Blakeslee in early to help us optimize the design,â€� Carlson says.
â€œWe developed our BIM design to produce the overall design, and then we compared that to Blakesleeâ€™s BIM design to develop special
component breakdowns and efficient connections.â€�
Marion Avenue Bridges, Southington, CT
A two-bridge project in Southington, CT, is taking advantage of precast concrete and Accelerated Bridge
Construction (ABC) techniques to minimize construction time and reduce user costs for detours by reducing
closure time on the bridge to less than 56 hours.
The twin east- and westbound bridges, on Interstate 84 over Marion Avenue, replace 1963 structures and will
feature 47-inch-deep precast concrete PCEF bulb-tee girders approximately 102.5 feet long. Northeast
Prestressed Products also is providing precast concrete approach slabs, which were redesigned to provide
larger slabs resulting in fewer closure joints. The project was designed by the Connecticut Department of
The precast concrete components were fabricated in the plant by Northeast Prestressed Products and delivered
to a staging area near the bridge.
University Station Parking Garage, Westwood, MA
Developers of the new 2 million-square-foot University Station multi-use project near the Route 128 MBTA commuter
rail line in Westwood, Mass., have begun construction on the first phases, which will include an apartment complex
with a total-precast concrete parking structure at its core.
When completed, the $500-million project will include 750,000 square feet of retail space, a 350,000-square-foot
Class A office building, 650 residential units, up to 160 hotel units and an assisted-living and memory-care facility
with 100 units, according to the Boston Business Journal.
The first phase, to open in the spring of 2015, will feature 550,000 square feet of retail space. That will be followed
by the Gables at University Station, a 350-unit luxury residential development planned to open that summer, BBJ reported.
Later phases will add the offices, hotel and additional residences and retail.
The residences are being designed in the â€œTexas wrapâ€� format that the developer has used on other projects. In this
design, a parking structure is constructed at the center and residential spaces are wrapped around that core, leaving
some facades of the parking structure open. The precaster on the project is Blakeslee Prestress, which has worked with
the general contractor on a total-precast concrete parking structure in the past.
Designing High Performance Parking Structures
In partnership with the International Parking Institute
Presenter : Rita Seraderian, PE, LEED AP
Description: PCI is partnering with the International Parking Institute (IPI) to bring you
this webinar regarding parking structures. Parking structures have changed a lot over the past decade.
Today's parking structures have to be built sustainably, reduce operational and maintenance costs, last
longer, and have more stringent aesthetic requirements. In many cases, they have to be high performance
structures exceeding standard expectations. This presentation will explain what a high performance parking
structure is, as well as how to design and build them utilizing high performance precast concrete. The
latest innovations and design methodologies, including connections, proper detailing and maintenance will
be discussed. Aesthetic options and versatility will also be presented.
Learning Objectives :
- Describe the primary attributes of a high performance parking structure.
- Discuss the latest innovations in parking structure design.
- Explain the differences in various structural systems for parking structures.
- Describe proper maintenance procedures for parking structures.
Using Life Cycle Assessment in Designing High-Performance Buildings
Presenter: Emily Lorenz, P.E., LEED AP BD+C
August 19 and 21
Description: Sustainability is a concept that we all strive for in our building designs.
As we move toward more-sustainable designs, high-performance buildings require consideration of
an increasing number of interdependent design choices. And not only do we need to design to
reduce environmental impact, but we need to design buildings to adapt to climate change. High
performance structures go beyond being built sustainably to include other aspects such as
resiliency and focus on long-term performance.
This presentation will describe high-performance buildings, as well as key elements to their
performance. It will explain topics related to sustainability, including life-cycle assessment,
environmental product declarations, and environmental impacts. The presenter will discuss the
importance of considering a full set of environmental impacts during design. Finally, examples of
design choices based on various life-cycles will be compared. Case studies will be used to highlight
- Define high-performance buildings and building envelopes.
- Explain what LCAs, EDPs, and PCRs are and their relevance in high performance building design.
- Discuss the importance of considering a full set of environmental impacts during design.
- Describe the pitfalls of making design choices based on a limited life cycle.
FEATURED LEARN AT LUNCH PRESENTATION
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

PCI Announces New Blast Design Manual
PCI’s Blast-Resistant Design Manual, First Edition (MNL 141-12) is now available as an ePub at www.pci.org/epubs.
This manual describes the basic process of blast-resistant structural design for precast/prestressed concrete components.
It includes calculating blast loads on the component, determining the dynamic response of the component, checking the
response against specified performance criteria, designing the component connections, and checking the component for
adequate shear capacity. The emphasis in this manual is on blast loads from exterior explosions and the dynamic analysis
of blast-loaded structural components idealized as equivalent single degree of freedom systems. These assumptions simplify
the blast-resistant design procedure discussed in this manual, but they apply to many cases of practical interest for
anti-terrorism and force protection design. For more details and purchasing information, visit www.pci.org/epubs.
Curved Precast Concrete Bridges State-of-the-Art Report
