INTRODUCTION

Surface Penetrating Radar (SPR) investigations were carried out by Atkinson-Noland & Associates (ANA) at the Pershing Barracks at the U.S. Military Academy at West Point.

Personnel involved in the site work included Carlo Citto and Zach Adkison of ANA. Field work was done during the period from July 21 to July 24, 2014. The objective of the nondestructive testing using SPR was to locate floor framing members and determine typical cross sections at each floor. Additional SPR investigations were carried out by Carlo Citto on November 20, 2014 during the thermal imaging investigation. The purpose of the additional radar work was to confirm previous observations at selected locations and investigate typical construction of selected walls.

This report describes the investigation methods, locations evaluated, and the results of the investigations.

SPR Investigation 2 Atkinson-Noland & Associates, Inc. August 18, 2014 (Rev. December 23, 2014)

SURFACE PENETRATING RADAR INVESTIGATION

SPR was used at Pershing Barracks to investigate floor framing and typical cross sections at each floor. The equipment used was a Geophysical Survey Systems Incorporated (GSSI) SIR-3000 ground penetrating radar unit with 1600 MHz antenna. The SPR method involves the transmission of high frequency electromagnetic radio (radar) pulses into the object of interest and measuring the time elapsed between transmission, reflection off a buried discontinuity, and reception back at a surface radar antenna. A pulse of radar energy is generated on a dipole transmitting antenna that is placed on the surface of the floor or wall. The resulting wave of electromagnetic energy propagates into the material where portions of it are reflected back to the surface at discontinuities. The discontinuities where reflections occur are usually created by changes in electrical properties of the underlying material. Void spaces, which may be encountered, will also generate significant radar reflections due to a significant change in radar wave velocity at the interface.

Calibration Calibration of the radar antenna to determine approximate depth was performed at destructive probe locations that were performed by others under the direction of Robert Silman Associates (RSA). Information from probes done at room 442, 443A, 346A, 238A and basement room 01 were used for the calibration. ANA observed only the probe opening at room 442. Observations at the other locations were provided by RSA.

Once the radar antenna is properly calibrated, SPR investigations can provide accurate information about the location and depth of embedded elements. Because materials typically encountered in construction have distinct reflections, SPR is also a reliable method to locate concealed elements. However, reconstructing a typical floor section is a complex process and requires a detailed interpretation of the radar traces. Typical floor construction at Pershing Barracks includes multiple layers of different materials with different dieletric constants and moisture content and this may affect the accuracy of the radar investigation. While the SPR survey provided detailed information about the floor construction, the estimated location (i.e.

depth) and typology of the elements comprising the structural floors may deviate from existing conditions.

Documentation Methodology and Observations At Pershing Barracks, 155 radar traces were collected by ANA. At each floor, SPR investigations were conducted at corridors, cadet rooms, and latrines. Locations were selected with the assistance of RSA. Radar traces collected along two orthogonal directions provided information about the framing direction of the floor beams. Using SPR, typical floor cross sections at each floor were reconstructed. Examples of radar profiles recorded during the field work are shown in Figure 1 through Figure 5. From these profiles, the distinctive elements of the floor system are clearly visible. A brief description of each floor section is provided below.

Appendix A provides detailed information about areas investigated and typical floor sections.

• North and south wings corridors o 2nd to 4th floor (except 3rd floor at north wing): terrazzo topping, setting bed with wire mesh, concrete filling, terra cotta flat arch between steel beams.

SPR Investigation 3 Atkinson-Noland & Associates, Inc. August 18, 2014 (Rev. December 23, 2014) o 3rd floor at north wing: terrazzo topping, setting bed with wire mesh, concrete fill between steel beams.

o 1st floor: terrazzo topping, setting bed with wire mesh, filling, masonry arch between steel beams.

• Main hall corridors o 3rd and 4th floors: terrazzo topping, setting bed with wire mesh, concrete filling, terra cotta flat arch between steel beams.

o 1st and 2nd floors: terrazzo topping, setting bed with wire mesh, filling, masonry arch between steel beams.

• North and south wings cadet rooms o 2nd to 4th floor: wood floor, concrete filling, terra cotta flat arch between steel beams.

o 3rd floor, rooms 345, 346, 348, and 350: the floor construction at these location was not investigated and may differ from typical construction.

o 1st floor: wood floor, filling, masonry arch between steel beams.

• Main wing cadet rooms o 3rd and 4th floors: wood floor, concrete filling, terra cotta flat arch between steel beams.

o 1st and 2nd floors: wood floor, filling, masonry arch between steel beams.

• North and south wings latrines o 2nd to 4th floor (except 3rd floor at north wing): floor tile, mortar bed with wire mesh (rebar mesh at showers), concrete filling, terra cotta flat arch between steel beams.

o 3rd floor at north wing: floor tile, mortar bed with wire mesh (rebar mesh at showers), concrete fill between steel beams.

o 1st floor: floor tile, mortar bed with wire mesh (rebar mesh at showers), filling, masonry arch between steel beams.

During the additional SPR work carried out on November 20, 2014, ANA investigated typical construction of selected partition walls along the main hall corridors on the 3rd and 4th floors. A limited investigation of the 1st floor exterior walls was also attempted from room 105. This investigation was not successful due to the metal lath in the plaster that covers the interior face of the wall. The presence of the metal lath prevented obtaining any information, with SPR, on the materials beyond the metal lath. The following partition walls were investigated:

• 4th floor o Wall between doors to rooms 433 and 435.

o Wall between doors to rooms 421 and 423.

o Wall between door to room 430 and adjacent column.

• 3rd floor o Wall between doors to rooms 333 and 335.

o Wall between doors to rooms 322 and 324.

o Wall between door to rooms 332 and 334.

Based on the investigation results, the partition walls appear to be 6” CMU walls with empty cells. An example of radar profile recorded at one of the corridor walls is shown in Figure 6.

Attention: Mr. Michael Chiodo, P.E.

Subject: WELDABILITY AND MECHANICAL PROPERTY DETERMINATIONS

OF STEEL COUPONS WEST POINT PERSHING BARRACKS RSA

PROJECT NO. NO. 16034

1.0 INTRODUCTION

LPI was requested by Robert Silman Associates to provide engineering services in determining the weldability of two steel coupons removed from structural members from the Pershing Barracks on the campus of the West Point Military Academy, in West Point, NY. A third coupon from the Pershing Barracks was submitted for a determination of mechanical properties. We were advised that the Pershing Barracks were built in the 1890’s. In this regard, if should be noted that there were no universal governing standards for steel composition for this vintage material.

2.0 WORK SCOPE

To this end, LPI performed visual examination, chemical analysis, metallography, and weldability determination on the submitted steel coupons.

3.0 PROCEDURES AND OBSERVATIONS

3.1 Visual Examination

The submitted coupons, shown in the as-received condition in Fig. 1, were identified as Room No.16, Room No. 20, and Steam Room. Arrows on the wrapping materials identified the longitudinal direction of the structural members from which the coupons were removed, as show in Fig. 1. The coupons from

PERSHING BARRACKS FIELD INVESTIGATION REPORT ║ FOUOJ-4

Robert Silman Associates September 9, 2014 Attention: Mr. Michael Chiodo, P.E. Report No. F14359-Rev 1

Room Nos. 16 and 20 consisted of saw cut square sections, as shown in Fig. 2.

The coupon identified as Room No. 16 measured 1.5 in. long x 1.8 in. wide and varied in thickness from 0.60 to 0.80 in. The coupon identified as Room No. 20 measured 1.9 in. long x 2.1 in. wide and varied in thickness from 0.45 to 0.75 in.

The coupon identified as Steam Room measured 6.25 in. long x 1.60 in. wide and varied in thickness from 0.60 to 0.80 in.

3.2 Chemical Analysis

Compositions of the coupons were determined by direct reading atomic emissions spectroscopy. Results of the analysis, given in Table 1, revealed that both coupons did not conform to the compositional limits of ASTM A36, “Standard Specification for Carbon Structural Steel” with phosphorous and sulfur in excess of that specified.

3.3 Tensile Testing

One 0.505 in. round tensile specimen was machined from the sample identified as the Steam Room and tested in accordance with ASTM A370, “Standard Test Methods and Definitions for Mechanical Testing of Steel Products”. For the sake of comparison, the results of the testing, presented in Table 1, revealed that the sample from the Steam Room conformed to the mechanical properties specified for ASTM A36 grade structural steel.

3.4 Metallographic Examination

One longitudinal microspecimen was prepared from the coupons identified as Room Nos. 16 and 20 in accordance with standard metallographic procedures. As shown in Fig. 3, suitable etching revealed the general microstructures of coupons from Rooms No. 16 and 20 consisted of pearlite in a ferrite matrix. Both microstructures were considered typical of plain carbon structural steel.

3.5 Weldability Determination

The weldability of each coupon was determined by the carbon equivalent (CE) method according to the following equation:

CE = C + (Mn)/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15 (1)

The CE’s of the coupons from Room Nos. 16 and 20 were 0.198 and 0.212, respectively. With CEs between 0.2 and 0.3 and actual carbon content (wt%) on the order of 0.1, the hydrogen control method is recommended. By this method, the estimated preheat necessary to allow enough hydrogen to diffuse out of the joint and prohibit cracking is determined using the compositional parameter (PCM) as follows:

PCM = C + Si/30 + Mn/20 + Cu/20 + Ni/60 + Cr/20 + Mo/15 + V/10 + 5B (2)

The PCM’s of the coupons from Room Nos. 16 and 20 were 0.135 and 0.153, respectively. The PCM’s and thicknesses of the coupons were used to determine the minimum preheat and interpass temperatures. Taking into consideration that it is an existing structure being modified and assuming E70XX low hydrogen welding electrodes will be utilized, the recommended minimum preheat and interpass temperatures were determined to be 65°F.

Attention: Mr. Michael Chiodo, P.E. Report No. F14359-Rev 1

4.0 CONCLUSIONS AND RECOMMENDATIONS

Results of this analysis revealed that the coupons from coupons from Room Nos. 16 and 20 did not conform to the compositional requirements of ASTM A36 structural steel due to the presence of phosphorous and sulfur contents in excess of that specified. The mechanical properties of the coupon from the Steam Room conformed to those specified for A36 structural steel.

The microstructures of the coupon materials consisted of grains of ferrite and pearlite, consistent with plain carbon steel. Based upon carbon equivalent calculations, the coupons were determined to be readily weldable using E7018 low hydrogen electrodes with minimum preheat and interpass temperatures of 65°F. That the phosphorous and sulfur likely exceed that specified for ASTM A36, strict compliance to preheat and interpass temperatures must be assured to preclude hot cracking during welding.

INTRODUCTION

Thermal imaging, also referred to as infrared thermography (IRT), was carried out by Atkinson- Noland & Associates (ANA) at the Pershing Barracks at the U.S. Military Academy at West Point. Carlo Citto of ANA was on site November 20, 2014 to conduct the field work.

The objective of the thermal imaging was to detect moisture variations in the façade, the presence of thermal bridging or air exfiltration, or possibly detect previous alterations if they impacted the exterior wall cross section. This report describes the investigation methods, locations evaluated, and the results of the investigations.

THERMAL IMAGING INVESTIGATION

A FLIR T420 thermal imaging camera was used to evaluate the exterior building envelop at the Pershing Barracks. An infrared camera measures and images the emitted infrared radiation from an object. Among others parameters, the emitted radiation is function of the object surface temperature. Thermal imaging was used to detect moisture variations in the exterior walls, the presence of thermal bridging or air infiltration, or possibly detect previous structural alterations

PERSHING BARRACKS FIELD INVESTIGATION REPORT ║ FOUO L-3

IRT Investigation 2 Atkinson-Noland & Associates, Inc. December 23, 2014 to the exterior walls. These events, if present, are likely to produce differences in temperature distribution at the surface of the wall that are captured by an infrared camera.

Documentation Methodology and Observations The thermal imaging of each building elevation was conducted primarily from ground level.

Portions of the north and west elevations were also surveyed from the roof of the adjacent buildings. The back surface of most parapets and the west and south walls of the clock tower were surveyed from the building roof. Most of the thermal images were taken at an angle with respect to the wall surface due to the vicinity of the adjacent buildings.

Temperatures below freezing were recorded at the Stewart International Airport in Newburgh, NY the night before the investigation.
