At this project the United Nations UN Womens Division was renovating the 17th-20th floors.  The concrete in this building is a very poor ashcrete from the early 1900’s.  The fire sprinkler contractor hired Atlas to do pull testing on their fire sprinkler pipe threaded rod anchors installed with Hilti HY200.  Its very important to pull test any epoxy anchor but especially overhead epoxy anchors due to the high probability of installer error or the substrate is too weak to support the epoxy system.  The ceiling contractor hired us to do pull testing on their ceiling anchors.  The anchors tested for the ceiling anchors were Ramset SPC114, Redhead Large Diameter Tapcon LDT130, and Simpson Strongtie 3/8th Stud Pin #PSLV3-125100.  The best performing anchor was the Redhead LDT.
