Bristol Recreation Center, Bristol, CT

Bristol Recreation Center, Bristol, CT

The new Recreation Center in Bristol, Connecticut, features a hybrid steel and precast concrete design that takes advantage of precast concrete's structural and architectural benefits. The new 40,000 square-foot center features a variety of amenities, including a gymnasium and embedded designs for the Boys and Girls Club.

A unique feature was the casting of various panels with the Boys and Girls Club logo and a preamble, which were erected at the entrance lobby welcoming visitors.

The precast concrete load-bearing walls were installed and braced, with the steel roof trusses bearing on a continuous shelf provided at the notched backside of the panels. The panels’ insulation extends to the roof insulation, creating a completely thermally efficient envelope. The trusses span 95 feet.

The precast concrete components were fabricated by Coreslab Structures (CONN), Inc.

Kent Hospital Ambulatory Service Pavilion, Warwick, RI

Kent Hospital Ambulatory Service Pavilion

Officials at Kent Hospital in Warwick, Rhode Island, needed to expand their facility to provide better services while offering easy access to existing services. The hospital partnered with Seavest Healthcare Properties to develop (and lease to the hospital) a two-story medical office building that includes basement-level support services. The new 66,503-square-foot, two-story building features architectural precast concrete wall panels that provide the required fast and aesthetically pleasing appearance.

The building’s exterior skin of full-height precast concrete panels feature four pigments and colored aggregates that create the illusion of several shades of red, providing a dynamic, contrasting appearance, Harris explains. A variety of reveals divide the façade into rectangular sections, each with a different texture, creating visual interest. Punched windows appear regularly along the façade and were cast into the panels along with several finishes on each of the panels.

Precaster Coreslab Structures (CONN) Inc. worked closely with Steffian Bradley Architects and general contractor Dimeo Construction to cast the 78 panels to exact specifications. The panels were delivered in a horizontal format on a flatbed trailer and then were maneuvered into a vertical position for erection, making efficient use of the two-story design and multiple window penetrations.

The precast concrete components were fabricated by Coreslab Structures (CONN), Inc.

Chain Bridge Road Pedestrian Bridge, Fairfax, VA

Chain Bridge Road Pedestrian Bridge Chain Bridge Road Pedestrian Bridge

Construction began earlier this year on a new bridge to replace the 87-year old existing structure on Chain Bridge Road at Kenmore Drive, near downtown Fairfax Virginia. According to the City’s project overview, the goals of the project are to replace the aging bridge over Accotink Creek, install new sidewalks and multipurpose trails, and a new pedestrian bridge.

Fairfax is cited as one of the “Top 25 Places to Live Well� by Forbes magazine. One of the reasons Fairfax is deemed so livable is its focus on recreational facilities and pedestrian and bike friendly trails. In keeping with this tradition, the new 52-foot pedestrian bridge, located in the historical district of Fairfax, was designed to match “the architectural style of historic downtown.�

The double tees used for this project are NEXT Beam double tees. The NEXT Beam (New England Extreme Tee) was developed as a more efficient cross section for bridges that are 30-90 feet long. The beam for this bridge features NEXT Beams with curved legs that form an arch in keeping with the historical character of the design. To form the arch, Hamilton Form provided a curved stem filler for use in the NEXT Beam form previously made by Hamilton Form. Additional details included spandrel panels with a stone veneer, concrete railings and precast deck slabs.

Northeast Prestressed Products (NPP) in Cressona, Pennsylvania supplied the prestressed concrete products for the project.

Using Life Cycle Assessment in Designing High-Performance Buildings

Risk

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 information presented.

Learning Objectives:

  • 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

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.

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.

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 document was written and intended to provide bridge owners, designers, fabricators and engineers an up-to-date reference in developing precast concrete bridge solutions for curved geometric situations. The topics include: Straight Girders chorded from Pier to Pier, Straight Girders Segments with Splices within the Spans, and Curved Precast Girders.  Each case study reviews project specific information, the structural system selected, construction techniques used and the lessons learned.
