Solid Waste Authority Transfer Station Floor (Palm Beach Gardens, FL)

Highlights

Resource Stewardship in Use: durable surface for high use infrastructure
Resource Stewardship in Supply Chain: reclaimed waste ingredients
Financial Stewardship: savings in construction cost and downtime

Although the floors are made with specialty components such as iron aggregates, impact from garbage trucks unloading and abrasion from heavy equipment moving trash can shorten the average transfer floor life to only 1 to 3 years. For the Solid Waste Authority, the downtime of any plant and the logistics of diverting continually accumulating trash are paramount. Floor rehabilitation typically averages 2 months of construction time before the floor goes back into operation.

University of North Florida Social Sciences Building, Jacksonville, FL

Highlights

Resource Stewardship in Use: energy efficiency, white cement to reduce heat island effect
Resource Stewardship in Supply Chain: recycled content in brick and insulation, reduced site disturbance
Financial Stewardship: lowered operating costs
Aesthetics: set in nature preserve, architecturally interesting façade integrated at factory to reduce site impacts

The University of North Florida (UNF) is set in a nature preserve, and administrators felt that the new Social Sciences building should blend with its green environment while also being sustainable. The building is three stories tall, and is 70,600 ft2 (6600 m2). The building has many environmentally friendly features, including waterless urinals, an emphasis on natural light, energy-efficient heating and mechanical systems, and an irrigation system that uses recycled water.

Four Seasons Hotel and Tower (Miami, FL)

Highlights:

Resource Stewardship in Use: mixed use urban development
Resource Stewardship in Supply Chain: reclaimed waste ingredients enabled use of local aggregate
Safety and Stability: very tall building designed to withstand hurricane force winds
Financial Stewardship: savings in construction
Aesthetics: tall tower graces urban skyline

At 750 ft (229 m), the Four Seasons Hotel and Tower is the tallest building in Florida, designed with concrete strengths up to fc′ = 10,000 psi (69 MPa). Modulus of elasticity requirements ranged from 4 to 6 million psi (28 to 42 GPa). The dense reinforcement configurations, particularly in the core of the building, required that the concrete maintain high workability even with temperatures close to 100°F (38°C) for up to 2 hours from the time of batching.

Cecil C. Humphreys School of Law, University of Memphis, Memphis, TN

Highlights:

Resource Stewardship in Use: restoration of historical building for new use
Safety and Stability: retrofits to meet seismic codes
Aesthetics: grand historical building enters new life as law school

The Cecil C. Humphreys School of Law is housed in the historic structure that once housed Memphis Customs, the Federal Court House, and the Post Office. The 140,000 ft2 (13,006 m2) building was originally built in the early 1880s, and had several additions during the early 1900s. The granite, marble, and limestone used in the building had held up well, but the building needed to be retrofit to meet earthquake building codes. The building sits near the New Madrid Fault Line, known for a series of major earthquakes in the early 1800s.
