Site Identification of the GNSS Monument Site Name : Dauphin Island Four Character ID : ALDI Monument Inscription : IERS DOMES Number : 49396M001 CDP Number : Monument Description : STEEL MAST Height of the Monument : Monument Foundation : The main building was constructed in 1954 as : military barracks with double wide and thick : concrete block. The addition was made in 1972 : using standard concrete blocks. The foundation : is a 3' spread footing approximately 36" below : the ground with reinforced concrete slab floors Foundation Depth : Marker Description : Date Installed : 2008-01-09T00:00Z Geologic Characteristic : Bedrock Type : Bedrock Condition : Fracture Spacing : Fault zones nearby : Distance/activity : Additional Information : The antenna is mounted on a 4" X 4" X 3/8" : stainless steel(ss) plate welded to a 2" X 2' - : 316 sch. 40 ss pipe. The pipe is welded to a : 3" to 2" - 316 ss coupling. The coupling is : welded to a 316 ss machine cap welded to a 2" X : 6' - 316 ss sch. 80 pipe. Spaced 2'3" from wall : by 6 - 3/8" X 1-1/2" 316 ss flat bar legs at 45 : degree angles with one diagonally welded piece : between the three legs either side. The 6 legs : are bloted through the wall with 5/8" ss : carriage blots. The blots are locked into place : in the interior of building with 3'4" X 4" X : 3/8" ss 316 flat bar. The antenna is mounted : on a two story building (24' tall) - Dauphin : Island Sea Lab (The State of Alabama Marine : Science Instittution) - with approximately 3'8" : above the roof line. 2.
