275 Albany Street, Boston, MA
Construction is underway on Troy Boston, a residential apartment community in the South End of Boston. The
$185-million project, designed as a sustainable, mixed-use complex, features precast hollowcore slabs for
the ceiling/flooring units, which will speed up construction and provide other benefits.
The development consists of two residential towers and approximately 6,000 square feet of retail
space, according to Gerding Edlen and Normandy Real Estate Partners, the co-developers. The towers
contain 378 apartment units, including 38 affordable-housing units, and ground-floor retail space
for shopping, restaurants and cafes. A 180-car above-ground parking structure also is part of the
development. A fitness center, pool deck and lounges are among the amenities offered.
A total of 1,539 precast hollowcore planks (944 for the North building and 595 for the South building),
covering 238,193 square feet, are being fabricated for the project, which is expected to achieve LEED
Gold certification. The precast hollowcore planks were fabricated by J.P. Carrara & Sons, Inc.
Sand Hill Bridge, Middlebury, VT
Designers of the new Sand Hill Bridge in Middlebury, VT, 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 beams that span above a
precast concrete arch that supports only its own dead load.
“We looked at a lot of options, and the NEXT beams provided the ideal solution,” says
Greg Goodrich, assistant project manager at VHB Engineering. The use of all precast concrete components
accelerated construction, which was critical. “Due to these being archaeologically sensitive areas,
there was no space for a temporary bridge, and the roadway was too narrow to maintain traffic during
construction,” Goodrich says. “And the detour was 30 miles, so the closure time had
to be minimized.”
The schedule allowed only 45 days for closure, and the prefabricated components aided the
contractor’s efforts to meet that tight timetable. 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 (New England Extreme Tee) D beams were then used to construct the bridge. The precast
concrete components were fabricated by J.P. Carrara & Sons, Inc. (Link)
Gillette Stadium Office Addition, Foxborough, MA
To expand administrative space at Gillette Stadium, home to the NFL New England Patriots, owners
are creating a two-story, 25,000-square-foot addition to the east side of the stadium. In an effort
to match the existing façade and fast-track the project, designers chose precast concrete
architectural wall panels and other decorative elements for the façade.
The construction timetable was shortened when the city’s planning board agreed the addition
qualified as a minor renovation that did not require a long site-plan review. That created a fast-track
design that was easily met by precast concrete’s ability to cast components while the site was
prepared and steel structural framing was erected. “The precast panels were being cast as the
footings were being poured, so they were ready when the site was ready,” says Gerald K. Grassby,
sales associate at Strescon Limited, the precaster.
The precast concrete components were fabricated by Strescon, Ltd.
Blakeslee Hosts ACE High-School Program
Blakeslee Prestress Inc. in Branford, Connecticut, recently hosted local high-school students who participate in a school
program that exposes them to various professions and activities within the construction industry.
The ACE (Architecture-Construction-Engineering) Mentor program, founded nationwide in 1994, coordinates programs for
high-school students interested in construction fields. It teams them with mentors who are professionals in those
industries to provide presentations and tours. The New Haven Chapter consists of students from 17 area high schools
who are taking courses in engineering or drafting or have summer construction experience.

Resiliency - Surviving the Storm
Presenter: Steve Szoke, PE
May 27 and 29
Description: The construction industry has come a long way in building more sustainable
structures, but we must also design and build for resiliency. Resiliency is the ability
of a structure to resist natural and manmade hazards such as earthquakes, severe storms
and even terrorists attacks. High performance precast concrete building systems
inherently provide resiliency and can extend a structure’s service life
significantly. This presentation will discuss multi-hazard protection primarily
related to storm design. It will provide an overview of storm design including
addressing high winds, impact resistance, and discuss some ways high performance
precast concrete can be used to protect structures. Other topics include FEMA 361
shelters, reinforced home design, and infrastructure.
- Define resiliency
- Discuss storm design methodologies using precast concrete
- Identify key factors that need to be addressed to design and build storm resistant structures
- Explain FEMA 361 and how precast concrete can be used to meet its requirements
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
This publication details the application of curved precast concrete bridge design, fabrication, construction techniques, and
considerations through the study of twelve related projects and constitutes a state of the art report on this topic. The
