Original in concept, size and complexity, this 1.5-acre rain forest ecosystem demanded two years of intensive research by Alvine
Engineering's team. Visits to several zoo facilities brought ideas for just a portion of the rain forest exhibit
which was completed in 1992.
Simulating a rain forest was a test of both man's knowledge of his environment, and the reliability of proven engineering
designs, techniques and principles. From the use of engineering concepts to selection of components, inventive solutions were
required for problems not previously faced in MEP systems design.
Survival of the Jungle's rare plant and animal residents directly depends on the efficient and reliable operation of the
facility's mechanical and electrical systems. Water temperatures need to be maintained at 75° F to 80° F, and air temperatures
need to be kept between the high of 85° F and a winter low of 65° F, with relative humidity requirements of 80-85%. Fogging
systems within jungle trees utilize deionized water and provide "misting" to increase humidity levels and promote plant
growth.
An award-winning project...
In 1993, Alvine Engineering received an Engineering Excellence Grand Award by the American Consulting Engineers Council of
Nebraska and an Outstanding Engineering Achievement Award by the National Society of Professional Engineers.
