PLACE OF PERFORMANCE

Mount Rushmore National Memorial

HWY 244 Building 13000 Suite 1, Keystone, SD. 57751

3.

PERFORMANCE HISTORY

A. Photogrammetry was performed on the Sculpture in 1998. The image of the sculpture was analyzed revealing 144 inconsistencies (Attachment A), and 22 separate rock blocks within the sculpture (Attachment B). Rock Block analysis revealed 2 “Potential Key” blocks (R16 and L17), and one block of Interest (W4), in addition to one block that has been previously measured (W1) as defined in Goodman and Shi [1985] (Attachment C).

B. A Rock Block Monitoring System was installed in 1998 to monitor these 4 blocks. This system used electric diodes to continuously monitor the fluctuations in crack width. During the period 2009 to 2011, the diode system was replaced with Strain Gauges as the measurement component. The componentry of this data collection system is listed below in section 4.

C. Rudimentary monitoring of rock block W-1 began with the initial analysis of the sculpture in 1970 with 6 stainless steel buttons mounted behind Washington’s head providing measurement points. All four rock blocks; W1, W4, R16 and L17 have been monitored from 1998 - 2008 utilizing the diode system and 2014 - 2024 using a fiber optic system. Data exists for these monitoring periods.

4.

CURRENT COMPONENTRY

A. 12 monitoring locations consisting of: 2 Type 304 stainless steel support cylindrical rods anchored into the granite perpendicular to the rock face; standard laboratory swivel clamps mounted to the stainless steel rods, supporting Type 36 invar cylindrical rods mounted into the swivel clamps paralleling the surface of the granite. The invar rods support invar tabs and machined blocks, the strain gauges are attached to the invar tabs, suspended and flexed across to a machined block. Camouflaged PVC protective enclosures on all stations.

B. 12 Micron Optic’s os3110 weld-able optic strain gauges and 4 Micron Optic’s os4310 non-metallic temperature gauge.

C. Approximately 100 meters of multimode fiber optic line extend into 3 junction boxes. Approximately 80 meters of single strand fiber leads from the junction boxes to the 12 Micron Optic’s gauges and 4 temperature gauges in succession.

D. Modem and Nuc computer E. 1, Micron Optic’s si155-EV-04-1500-1600-0010-NO optical Sensing Interrogator

F. Micron Optic’s sensing analysis software “Enlight”
