Hospital Quiet Zone

Conversations and the cacophony emanating from telephones, alarms, televisions, carts, doors, medical, and mechanical equipment ensure noise is ever-present in U.S. hospitals. Various economic incentives, regulatory measures, and design guidelines have been developed over the past decade to encourage hospitals to address this problem.

Bearing Pad Durability in Precast Concrete Garages

garage_File Opener

Bearing pads are used widely in precast concrete parking garages. They function as buffers between the separate concrete members to prevent damage and facilitate movement (much like cartilage between bones at joints). Bearing pads should last for the design life of the structure, but need to be replaced when they are not sufficiently durable. The ‘surgery’ to replace the pads properly is a complex operation, with few published guidelines.

Minimizing Environmental Impacts with Clay Roofing

clay_Monarch-Custom Blend

Clay roof tiles offer numerous benefits to commercial and residential projects. Inherently, the material is associated with minimal environmental impact in its sourcing, extraction, as well as manufacture. As environmental awareness in building design and construction has increased, the greatest focus has been on sustainable building materials, both in manufacture and performance.

Resisting natural disasters and reducing environmental impacts are major challenges in the United States. During an average year, there are 10 tropical storms (six of which become hurricanes) and more than 1200 tornadoes touching down. In South Florida, Hurricane Andrew left a wake of destruction in 1992 that totaled more than $25 billion in property damage and resulted in 44 fatalities.

A Face-lift: Travertine cladding and paver repairs

travertine_Capital_One_Plaza_02

Built in 1982, Capital One Plaza is a 22-story structure in Houston, Texas. The building exterior wall consists of ribbon windows and 30-mm (1 1⁄8-in.) thick travertine panels connected to precast concrete spandrel panels.The cladding was fabricated by placing travertine panels face-down in formwork, installing stainless steel wire loop anchors into predrilled holes in their back surface, and casting concrete against this to encapsulate the stainless steel anchors.

Reflecting on Heat Transfer Reduction

Prodex-Renault motors

Most forms of building insulation—fiberglass, mineral fibers, cellulose, and cellular plastic—play a key role in making buildings energy-efficient and in reducing electrical peak demand. However, the amount of material that can be added to building walls or roof-ceiling assemblies is limited either by physical dimensions of the framing (ceiling frames) or adverse effects of over-insulating (weight, heat and moisture retention, and ventilation restrictions).
