I. INTRODUCTION:

On November 30th, 2023, we were present at the above referenced facility to perform a review of the existing building enclosure:

In general, our scope of work was as follows:

A. Perform a visual review of the in-place exterior wall assembly;

B. Obtain photographs to substantiate our findings;

C. Based on the information obtained, develop a report as to the condition of the exterior wall assembly with conclusions and recommendations for repair and/or replacement.

Our work was requested and authorized by Tim Grundtner of RSP Architects, and authorized on site by Dan Nickols of Fort Snelling’s Facility Operations.

II. BACKGROUND INFORMATION:

Building 505 was constructed in 1977 (with as-built drawings dated 1983) at the North-East corner of the Minneapolis-St. Paul International Airport on what is now part of the Minneapolis-

St. Paul Joint Air Reserve Station of Fort Snelling. A small entry addition was added (date unknown) to the building after the initial construction. An enclosed connecting walkway was added at the time of construction for the adjacent building (506) for secure access between the two buildings.

The existing exterior wall assembly consists of exterior brick veneer, 1.5” expanded polystyrene insulation, and a CMU backup wall. There is flashing material present at the head and sill of each window (assumption based on test openings at 2 window conditions), but the wall assembly does not include a vapor barrier or coating of any kind.

IV. CONCLUSIONS & RECOMMENDATIONS:

HEAD CONDITIONS:

Significant damage was found on and around the steel lintels at all window locations throughout the building. After a series of test openings, it was determined that the window heads are not properly flashed to accommodate the moisture infiltrating the wall assembly. Though no water appears to be entering the building any more after replacing the window assemblies throughout the building (verified by water testing done on 12/07/23), water is still entering the wall assembly.

Because the steel lintel bottom plate is exposed and ends flush with the brick, water is able to either get back into the wall assembly under the head flashing, or it is lead to the underside of the steel lintel bottom plate through capillary action. Under the head condition in the window opening, without direct sunlight, the assembly isn’t able to dry properly and the water sits for long periods of time on the steel lintel plate. During freeze/thaw cycles, water expands within the assembly and causes the steel lintel plate to deflect away from the brick, delaminating it from the mortar joint. This would also cause small cracks to form in the exterior coating, allowing the moisture to penetrate directly to the steel, causing the steel to rust over time. We recommend removing and replacing a minimum of 4 courses of brick above each head, repairing and applying a corrosion resistant coating to the steel lintel bottom plates as necessary, and installing through-wall flashing (with termination bar, stainless steel drip edge, end dams of 2” minimum, weep vents, and a thermal break) at the head of every exterior wall opening.

SILL CONDITIONS:

Deterioration and evidence of water infiltration is found at every window sill location with varying severity. The sills consist of horizontal bricks with mortar joints, and have sealant joints at either side of the window opening that are failing, delaminating and cracking. After a series of test openings, it was determined that the window sills are not properly flashed to accommodate the moisture infiltrating the wall assembly. Though no water appears to be entering the building any more after replacing the window assemblies throughout the building (verified by water testing done on 12/07/23) and replacement of the roof in 2021, water is still entering the wall assembly.

Water enters the system through the mortar joints in the sill, and either sits on top of the brick directly under them, or makes its way backwards into the cavity wall assembly. Because of the small overhang of the sill, the mortar joint directly beneath it doesn’t get direct sunlight and doesn’t dry properly. Efflorescence in the masonry is an indication of this; it is a buildup of salts from water infiltration and gradual evaporation. We recommend removing the brick-and-mortar sill, installing through-wall flashing (with termination bar, stainless steel drip edge, end dams of

2” minimum, and a thermal break) at the sill, and replacing with a cast-stone sill (with a sloped top and a drip edge) at every window and louver location throughout the entire building. We also recommend cleaning the efflorescence and discoloration off of the brick, and repointing all discolored or deteriorated mortar throughout the entire building.

JAMB CONDITIONS:

The brick return at the jambs causes a thermal bridge in the wall assembly and can lead to excess moisture in the wall system in the form of condensation. We recommend removing the brick at each jamb, adding a thermal break between the brick veneer and the CMU back-up wall, installing a flashing membrane at the jamb, and reinstalling the face brick as necessary at all jamb locations throughout the entire building.

Date: February 6th, 2024 RSI Project #: 23-13945-07 Page 11

All information is submitted as the confidential property of our clients. Any copies or extractions are reserved pending our written approval.

EXISTING WALL ANCHORS:

At the locations where metal anchors are rusting and causing discoloration of the brick, we recommend removing the masonry anchors, cleaning the brick, and repointing the mortar joints as necessary. Where anchors appear to have damaged the brick, we recommend replacing bricks and repointing impacted mortar joints as necessary.

EXISTING MASONRY JOINTS:

All masonry sealant joints throughout the entire building are failing. This includes expansion joints, control joints, and joints around the existing brick sills (excluding the black sealant around the new window assemblies). We recommend replacing all sealant joints throughout the entire building.

EXISTING ROOF CAP:

At the location where the coping cap has detached from its keeper strip, we recommend reattachment as soon as possible to prevent water infiltration into the roof and wall assemblies.

WATER TESTING:

The water test (referenced above) consisted of a series of 3 two-hour tests conducted at a window opening. The interior wall is tested with a pin-point moisture meter to determine a baseline moisture level for the wall (average measurement of 6.6 baseline). Water is then directed at the exterior wall by an apparatus that simulates wind driven rain. After 2 hours, the interior wall is visually inspected for signs of water infiltration and tested again with the pin-point moisture meter to determine if the moisture level of the wall has increased from the baseline measurement.

This test was performed 3 times; below the window sill, on and around the window opening, and above the window head; each location was tested for 2 hours, for a total of 6 hours of water testing. No substantial increase of moisture or water infiltration was found on the interior wall

(average measurement of 7.7 after water testing).

The existing interior face of the CMU back-up wall shows signs of past water infiltration

(bubbling paint). Since the wall doesn’t have a high moisture level, we believe the paint bubbling was caused by past water intrusion via the original windows (recently replaced) and/or the old parapet cap condition (recently replaced). The recommended repairs should reduce the risk of further moisture issues in the CMU back-up wall.

Executive Summary

Pinyon Environmental, Inc., (Pinyon) presents the following report detailing the Hazardous Building

Material (HBM) and Radon Surveys conducted as part of the planning and design for the update/renovation of Building 505, US Army Reserve Center, located at 506 Roeder Circle, Fort Snelling, Minnesota 55111

(Figure 1, the Site). The mechanical room in Building 509 was also included in the HBM survey as this is the location where utility connections will be made for a new wash rack that is also part of the Building

505 renovation project.

The HBM and radon surveys were conducted the week of October 30, 2023. The HBM survey was conducted by Ms. Rachel Hernandez of Pinyon and Mr. Brett Brumbaugh of Castle Hill Associates on

October 30 and 31, 2023; and the radon survey was conducted by Mr. Brad Nyberg, Great River Radon

(GRR), under Minnesota License #MN00054 on October 30 through November 2, 2023. Castle Hill

Associates (asbestos and LBP) and GRR (radon) were subcontracted by Pinyon due to the specialized certification and licensing requirements for the surveys.

The two surveys indicated:

• Radon. Forty-six (46) radon samples were collected throughout Building 505 (Figures 2 and 3).

Analytical results indicated that one sample, collected from Room 113C (Figure 2), contained radon activity levels in excess of the Environmental Protection Agency (EPA) screening level of 4.0 picocuries per liter (pCi/L). The measured radon level in Room 113C was measured at 4.3 pCi/L. The radon survey is further detailed below in Section 1. Due to the Room 113C test results, Mr. Nyberg recommends re-testing Room 113C and all adjacent rooms that share a wall. The re-testing would be performed using Continuous Radon Monitors (CRM) to establish the most appropriate path forward to protect occupants. The 4 rooms that are recommended for re-testing using CRMs are 113C, 113, 113B, and 111 (Figure 2).

• Hazardous Building Materials (HBMs). Several building components associated with future construction or demolition were identified that have the potential to meet the definition of “hazardous waste” or regulated waste material if removed. This includes fluorescent bulbs, light ballasts, mercury switches, exit signs, emergency lights, smoke detectors, and fire extinguishers. A detailed list of the potential HBMs identified in Building 505 and the mechanical room of Building 509 is presented in

Section 2.

505 Roeder Circle, Fort Snelling, Minnesota 55111 Page 2

1. Radon Survey

Great River Radon (GRR) completed the Building 505 radon survey by collecting 46 samples at the locations identified on Figures 2 (1st Floor) and Figure 3 (2nd Floor). The purpose of the sampling was to evaluate indoor air radon levels of frequently occupied rooms, which include, but are not limited to, offices, work rooms, and common rooms. The building has two floors with no accessible areas below ground level. The sampling was conducted by GRR’s Minnesota licensed radon measurement and mitigation professional, Mr. Brad Nyberg (#MN00054).

1.1 Testing Procedures

The radon testing was initiated on October 30, 2023, by placing radon test kits (activated charcoal) at select locations throughout the building. The test kits were retrieved on November 2, 2023. The sampling was performed in accordance with the American National Standards Institute (ANSI) and American

Association of Radon Scientists and Technologists (AARST) procedures for radon testing. The sample locations were selected because facility personnel are likely to be present in these areas. The approved test kits were produced by Air Chek, Inc. of Mills River, North Carolina, and are approved by AARST.

The tests were conducted under ANSI/AARST protocol which requires:

• A test length of at least 48 hours.

• Tests to be located in breathing zones (between 20 inches and 96 inches from the floor).

• Ingress and egress activities be minimized.

• Indoor air temperatures above 65°F before and during sampling.

An overview of the radon sampling at the Property includes:

• On October 30, 2023, GRR placed 46 test kits throughout the building. The test kits were placed near the entrances in rooms identified on Figure 2 (1st floor) and Figure 3 (2nd floor). The sampling included 4 duplicate samples, and 5 blank samples and 37 primary samples.

• The test kits were left in place for over 48 hours, with retrieval of the kits on November 2, 2023.

• The HVAC system was operational when the test kits were placed, and when the test kits were retrieved.

• Upon collection of each sample, the test kits were sealed, and the date/time was documented. After the test kits were collected, sealed, and labeled, they were shipped to Air Chek, Inc. for analysis.

• The test kits were analyzed by Air Chek using a scintillation detector to count the gamma decay absorbed by the charcoal. The radon concentration for each sample was calculated using instrument calibration information.

505 Roeder Circle, Fort Snelling, Minnesota 55111 Page 3

• No test kits appeared to have been tampered with or moved in the time-period between deployment and retrieval.

Sample blanks were stored with the other testing devices. Upon deployment, the blanks were opened and then sealed immediately. The blanks were placed in Rooms 101, 116, 115, 127, and 209 (Figure 2 and

Figure 3). The blank sample cartridges were retrieved at the same time as all other testing devices and followed the same shipping to the laboratory. All blank sample results are expected to be under 0.3 picocuries per liter pCi/L.

1.2 Testing Results

The indoor radon sample laboratory report is presented in Appendix A. Radon levels in the samples collected at the Property ranged from <0.3 picocuries per liter (pCi/L) to 4.3 pCi/L. Blank sample results were less than 0.3 pCi/L. An overall summary of sample results is presented below in Table 1-1.

1.3 Conclusions

Based on laboratory analysis results of collected radon samples, one sample (Room 113C) exceeded EPA’s action level of 4.0 pCi/L (Figure 2).

To further evaluate this exceedance, it is recommended that Room 113C be retested and that all adjacent offices that share a wall also be tested. The recommended testing would use Continuous Radon Monitors

(CRM) to further evaluate risks and understand the extent of the potential impact. The four rooms recommended for CRM testing include 113C, 113, 113B, and 111.

2. Hazardous Building Materials Survey

Hazardous building materials include but are not limited to: asbestos (caulking, weather stripping, masonry joints); LBP; polychlorinated biphenyls (PCBs) in fluorescent light ballasts or electrical transformers;

mercury-containing fluorescent lamps, thermostats, and switches; and smoke detectors. The asbestos and

LBP survey for the Property is covered under a separate, stand-alone document prepared by Castle Hill

Associates (CHA). CHA is a subcontractor licensed and certified to conduct asbestos and LBP sampling in Minnesota. Pinyon and CHA together surveyed Building 505 and the mechanical room in Building 509, for mercury-containing devices, PCBs, and other potentially regulated equipment and/or building materials.

The non asbestos and LBP potentially hazardous building materials are covered below.

Pinyon and CHA surveyed Building 505 for PCB, mercury-containing equipment, and other potentially hazardous building materials on October 30 and November 1, 2023. The survey was conducted by experienced inspectors walking through the facility and documenting possible PCB-containing equipment, mercury-containing devices, and other potentially hazardous equipment and/or materials. No laboratory samples were collected. Two pad-mounted electrical transformers were noted outside of Building 505.

One transformer was observed northwest, and the 2nd west of Building 505. No leaks or stains were noted in the vicinity of either transformer.

Component removal or disassembly for internal inspection was not performed, except for HVAC system thermostats. The cover of approximately 10 HVAC system thermostats were removed and none contained mercury switches. Therefore, it was assumed that the Building 505 thermostats do not contain mercury.

Based solely on visual observation and prior experience, building components were identified and may require removal during construction or demolition and have the potential to meet the definition of

“hazardous waste” or other classification as a regulated waste material. Table 2-1 below provides a building component list and estimated quantities that were observed in Building 505 and the mechanical room of

Building 509.

No green markings were observed on fluorescent bulbs. Green markings suggest the bulbs may contain a small amount of mercury.

The use of PCBs was banned in 1978. Building 505 was constructed in 1979. Fluorescent light ballasts and other equipment, manufactured after 1978 likely do not contain PCBs. No markings were observed on the ballasts that would indicate the presence or non-presence of PCBs. Because of the construction date, it is possible that the building’s fluorescent lighting ballasts do not contain PCBs, but due to the lack of external markings, the actual content cannot be determined without laboratory analysis.

The building components referenced in Table 2-1 may require special handling if removal is performed.

Additional characterization may be required by receiving disposal facilities. The inspection was performed in a manner consistent with the level of care and expertise exercised by members of the hazardous building materials inspection and assessment profession. Those entities and persons involved with the inspection and generation of this report do not imply or guarantee that all potential materials on or in the structure have been identified. The inspection was intended to identify those accessible materials that were

505 Roeder Circle, Fort Snelling, Minnesota 55111 Page 6 reasonably suspect and were most likely to contain PCBs, mercury, or other potentially regulated equipment and/or materials.

BUILDINGS 505 & 509 – RENOVATION PROJECT

PROJECT SUMMARY

On October 30, 2023, Brett Brumbaugh of Castle Hill Associates performed an asbestos survey and lead (Pb) paint testing utilizing a Viken Detection Pb200i direct read X-Ray Fluorescence (XRF) analyzer prior to the planned interior renovations planned in Buildings 505 & 509 at the Ft.

Snelling USARC (United States Army Reserve Center) in Minneapolis, MN.

Building 505 was constructed in 1979 and is approximately 63,000 square feet (sf) in size. The building is on a concrete slab with no basement and has a flat roof rubber roof. The roof was recently replaced with an EDPM rubber roof and therefore not sampled due to warranty issues and conditions. Bulk samples were collected from suspect asbestos containing materials (ACM) that had not been sampled during previous asbestos surveys in the building. Thirty-eight (38) bulk samples were collected during the survey; this report summarizes the collection and laboratory analysis of the samples.

Building 509, which is a small metal maintenance shed, was tested because there is a water…
