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 the multi-hazard protection of precast concrete focusing on earthquake and blast design specifically. It will provide an overview of seismic and blast design with precast concrete, and will also address Anti-Terrorism Force Protection (ATFP), code changes, and how precast concrete can be used to meet them. 

Learning Objectives:
1. Discuss seismic and blast design methodologies using precast concrete.
2. Explain how precast concrete can be used to meet performance needs in seismic regions.
3. Discuss the United Facilities Criteria and recent changes related to ATFP.
4. Explain how precast concrete can be used to meet performance needs related to ATFP.

Description: 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:
1. Describe the primary attributes of a high performance parking structure
2. Discuss the latest innovations in parking structure design
3. Explain the differences in various structural systems for parking structures
4. Describe proper maintenance procedures for parking structures

Description: A structure’s envelope has considerable impact on its overall performance, as highlighted by recent code changes. The envelope not only serves as a barrier between the outside environment and conditioned space, but also as a part of the aesthetic expression for the structure. It must also serve as a protective shield against environmental forces. High-performance building envelopes can help reduce the overall energy consumption of a structure throughout the structure’s life, and maintain and protect its interior environment and occupants. 

This presentation will address what high performance building envelopes are, as well as key elements to their performance. It will discuss how to use precast concrete wall systems to meet the latest code requirements such as continuous insulation and air barriers, and include topics such as moisture management, thermal mass effect and how to calculate effective R-values, integration with other building systems, and more. This session will also touch on the idea of resilience. A structure must be able to resist environmental forces, such as high winds and earthquakes in order to protect life and fulfill its intended purpose. Case studies will be used to highlight information presented.

Learning Objectives:
Describe the three basic types of  precast concrete envelope systems
Describe new envelope code requirements
Explain thermal mass and how to use it to create more energy efficient buildings
Discuss moisture management methodologies

Description: Fire safety codes have changed over the years. The International Building Code now allows for substantial building areas and heights to be built with Type V construction (i.e. wood or light-gage steel framing) where an approved sprinkler system is provided. This shift toward active fire protection systems as the primary life safety component, and the decrease in containment and passive fire-resistant construction, has resulted in less resilient construction. Buildings relying solely on code-approved sprinklers leave themselves vulnerable to damage to the water supply and other defects. Precast concrete provides significantly enhanced passive fire protection due to its inherent inorganic composition. Containment by compartmentalizing the design with a precast concrete structural system limits damage and allows occupants more time to evacuate the premises. PCI recently published its updated fire manual including an International Code Council Evaluation Service (ICC-ES) report that allows its use as an alternate to code provisions. This presentation will provide an overview of fire safety design using the updated manual.

Learning Objectives:
1. Discuss the basics of a balanced approach to fire safety design
2. Describe the ASTM E 119 fire test procedure
3. Describe how to meet fire code requirements with precast concrete
4. Explain how to treat joints between precast elements for fire resistance

Description: The aesthetics of a structure are very important, as it is what most people identify with. High performance materials should provide aesthetic versatility in order to efficiently meet a structure’s architectural requirements. Precast concrete provides incredible aesthetic versatility from providing multiple colors and textures, to developing shapes, forms and very ornate details. Precast can also simulate or be veneered with natural materials providing all of their beauty, but with the added speed, durability, many other benefits of precast.  This presentation will provide an overview of the many finishes available with precast concrete, along with methodologies for achieving them. We will also discuss combining multiple finishes into single panels, veneers and embedded materials, selection of mix designs, approaches to achieving colors, proper specification, and procedures to ensure expectations are aligned.     

Learning Objectives:
1. Explain the finish options of precast concrete
2. Describe methods to achieve color, form and texture
3. Explain how clay products and natural stones can be veneered to precast concrete to speed construction and reduce costs
4. Discuss the latest innovations in aesthetics and finishes

Description: Part of a quality indoor environment is to ensure that sounds are clearly heard by intended listeners, and that unwanted sounds (noise) are isolated or absorbed. This is the art of architectural acoustics. This presentation will address basic acoustic design, including the sound insulating properties of precast concrete.  It will include topics such as sound transmission loss, absorption of sound, acceptable sound criteria, composite wall sections, and more. Sample problems and case studies will be used to highlight the concepts being discussed.    

Learning Objectives:
1. Describe the basic terms and concepts to acoustic design
2. Discuss the differences between sound absorption and sound insulation
3. Explain what a sound transmission coefficient is
4. Describe the benefits and approaches  of acoustic design with precast concrete
