Form Prepared by (full name) : Francine Coloma Date Prepared : 2018-08-15 Report Type : UPDATED If Update : Previous Site Log : inhc_20170213.log Modified/Added Sections : 3.2, 3.3, 4.1, 4.2 1. Site Identification of the GNSS Monument Site Name : HENDRICKS COUNTY Four Character ID : INHC Monument Inscription : IERS DOMES Number : (A9) CDP Number : (A4) Monument Description : STEEL MAST Height of the Monument : 3.15 m Monument Foundation : BRICK WALL ON ROOF OF 3 STORY COUNTY BUILDING, : CONSTRUCTED IN 1924 Foundation Depth : 2.13 m Marker Description : (CHISELLED CROSS/DIVOT/BRASS NAIL/etc) Date Installed : 2007-11-06T16:00Z Geologic Characteristic : CONGLOMERATE Bedrock Type : (IGNEOUS/METAMORPHIC/SEDIMENTARY) Bedrock Condition : (FRESH/JOINTED/WEATHERED) Fracture Spacing : (1-10 cm/11-50 cm/51-200 cm/over 200 cm) Fault zones nearby : (YES/NO/Name of the zone) Distance/activity : (multiple lines) Additional Information : The antenna is attached to the mast with a : 5/8"-11 x 2" stainless steel stud. This stud is : screwed into a tapped hole in a 1/2" thick : aluminum plate that is welded to the top of the : mast. The tapped hole is of course collinear : with the axis of the mast. The mast is an 80" : long piece of 3" (nominal) Schedule 40 aluminum : tube. The aluminum tube is 6061-T6 aluminum : alloy. The actual o.d. of the tube is 3.5". : The mast is attached to two horizontal strut : channels with conventional tube clamps. The two : strut channels are 1-5/8" x 1-5/8", 12 gage, : galvanized, slotted strut channels,each 2' long. : These are commonly referred to by the trade name : "Unistrut" or "Superstrut" although there are : several different brands of the same thing out : there. Each strut channel is attached to the : wall with two 1/2"-13 x 2" zinc plated bolts. : The struts are spaced about 30" vertically from : each other. The bolts are secured into the wall : with "hollow set" anchors that consist of a : split shell and a conical nut. As the bolt is : tightened, it draws the conical nut into the : shell and expands the shell against the 3/4" : diameter hole that is drilled into the wall with : a hammer-drill. Between the two struts, a 1/2"- : 11 x 7" passes through clearance holes in the : mast, a 4" long piece of strut for a spacer and : into another anchor in the wall. 2.
