Special Inspection/Materials Testing
NTI provided special inspection and materials testing in support of the new Asian Elephant habitat.  Construction of the $53 million project started in early June of 2013.  The 6.25-acre Elephant Lands is expected to provide the lively animals with more choice and freedom to stay active and socialize.  The habitat will involve construction of a new management building, an indoor viewing hall, and a life support facility.  Also included is the relocation of the Zoo’s train tracks, two new train trestles, and a new service road.  Duties include reinforced concrete, structural steel, ultrasonic weld evaluation, proprietary anchors, cold-formed steel framing, curtain wall, suspended ceiling, shotcrete, and soils special inspections.  
NTI  also designed and fabricated a 1,400 lb. 4’ x 4’ load test apparatus installed into the existing elephant habitat to measure elephant push and pull loads.  Elephant handlers coached the elephants to exert force on the apparatus which was recorded through a data acquisition system. The structural engineer utilized this data to confirm his cable fencing and bollard design.
