Financial Stewardship: construction speed
Aesthetics: architecturally complex structure with exposed concrete finish
This center played a prominent role in the 2010 Olympic Games in Vancouver as a training venue for Olympians and volunteers, as well as a central location for all recruitment and logistics. The project got off to a late start, so shortening construction time as much as possible was critical. The structure was architecturally intense, with curved top walls up to 40 ft (12 m) high and extensive reveals, recesses, and block-outs. The specified finish was a light sandblast and two coats of clear sealer, so quality finish was essential.
Resource Stewardship in Use: thermal performance
Safety and Stability: integrated fire safety
Financial Stewardship: accelerated construction schedule solution gained floor space and reduced costs
Aesthetics: neighborhood visual integration, additional detail allowed by precast strategy
This eight-story residential complex in Philadelphia, PA, incorporates 414,000 ft2 (38,500 m2) of premium residential and retail space in addition to 108,000 ft2 (10,000 m2) of parking. Domus covers a large city block, and its vast exterior surfaces were initially designed for masonry, including a wealth of visual details to harmonize with the brick façades of the adjacent University of Pennsylvania. When construction documents were 65% completed, the Houston, TX-based developer accelerated construction.
Resource Stewardship in Supply Chain: reduced materials in placement using shotcrete
Financial Stewardship: speed of construction
This large, mixed-use development project had an extremely tight construction schedule—the contractor had to place walls very quickly. As shown in Fig.1, shotcrete provided the solution: walls used one-sided formwork, shotcrete was applied, and then the free surface was finished by hand. Forms were then moved to the next wall and reused. With a trailer pump on site twice a week, between 80 and 130 yd3 (61 and 99 m3) of concrete could be shot in an average 8- to 10-hour day.
Financial Stewardship: low long term maintenance for taxpayer
Resource Stewardship in Use: stormwater management
Safety & Stability: public open space which promotes international understanding
When the City of Leawood, Kansas, implemented new regulations requiring developers to address stormwater runoff for the health of the community, local officials knew that their own construction practices would reflect the expected and required policies in the community.
Aesthetics: cottage units with fiber cement siding, thick windowsills
Financial Stewardship: affordable housing and utilities, reduced insurance
Resource Stewardship in Use: energy performance
Safety & Stability: durability, fire protection, noise attenuation
Although the number of sustainable construction projects has grown significantly across the United States during the past several years, unfortunately it remains uncommon to hear the word “affordable” associated with sustainable development. The Marion County Housing Authority (MCHA) of Oregon is challenging the myth that sustainable construction can't be affordable. In early 2006, MCHA broke ground on Hazelwood Estates, a cozy, 32-unit, senior community built on a former hazelnut orchard in Woodburn, Ore.
