Dear Bill:
1.0 Introduction
Hart & Hickman, PC (H&H) has prepared this report to document tenant upfit activities
completed at The Winston mixed-use development (formerly referred to as The Square at South
End) on the western portion of the West Boulevard Brownfields Property (Brownfields Project
No. 22076-18-060) (Site). The West Boulevard Brownfields Property is located northeast of the
intersection of S. Tryon Street and West Boulevard in Charlotte, Mecklenburg County, North
Carolina. The Site is identified as 222 West Boulevard and was redeveloped with two multi-
story buildings that are comprised of retail units and a leasing office on the ground floor and
apartment units on upper floors. The eastern part of the West Boulevard Brownfields Property is
developed with a 10-story office building and is under separate ownership. Therefore,
Brownfields-related activities performed on the eastern portion of Brownfields property will be
reported separately. A Site location map is included as Figure 1, and the redevelopment layout is
included as Figure 2 (Attachment A).

The North Carolina Department of Environmental Quality (DEQ)-approved Vapor Intrusion
Mitigation Plan (VIMP) included installation of a passive sub-slab depressurization system and
post-installation soil gas sampling in the mixed-use buildings. Vapor intrusion mitigation system
(VIMS) installation activities for the northern building were documented in H&H’s VIMS
Installation Completion Report dated February 8, 2022, and VIMS installation in the southern
building were documented in the VIMS Installation Completion Report dated March 9, 2022.
Briefly, the VIMS consists of a passive sub-slab depressurization system, which is comprised of
an interconnected system of vapor collection/conveyance piping installed in a permeable gravel
layer beneath the buildings. The sub-slab piping is connected to riser piping which extends
vertically through the building and discharges vapors through exhaust stacks installed above the
building roof. Empire Model TV04SS (stainless steel) turbine ventilator fans were installed on
the discharge end of the exhaust stacks on the roof. In addition, Vaporblock® Plus 20 (VBP20),
a vapor barrier manufactured by Viaflex, Inc. (Viaflex), formerly known as Raven Industries,
was installed between the gravel layer and the concrete slab of the buildings. The VIMS layout
in the southern building, where recent tenant upfit activities occurred, is included on Figure 3
(Attachment A).

The DEQ-approved VIMP included pre-occupancy sub-slab vapor sampling, along with three
post-occupancy sub-slab vapor sampling events. The pre-occupancy sampling was completed in
December 2021 and February 2022, which are documented in the VIMS Installation Completion
Reports. The first post-occupancy event was completed in July 2022 and was documented in the
VIMS Post-Installation Sampling Report dated October 19, 2022. The results of the pre-
occupancy sampling and the July 2022 post-occupancy sampling event indicated that the
calculated worst-case, cumulative carcinogenic and non-carcinogenic risks for residential and
non-residential exposure scenarios were below the DEQ and Environmental Protection Agency
(EPA) acceptable thresholds. Thus, the detected concentrations do not pose significant risk of
vapor intrusion above acceptable levels. The second post-occupancy sampling event was
performed in September 2023. Results of the September 2023 post-occupancy sampling event
will be reported under separate cover.

(NCBP 22076-18-060)_11-2-23.doc
The ground floor of the southern building was completed with multiple retail tenant spaces. One
retail space on the ground floor of the southern building, known as Commercial Space 01, was
designed to remain without a concrete slab for ease of future tenant upfit activities after the rest
of the building was fully constructed. Commercial Space 01 was completed with a concrete
ribbon slab along the perimeter of the retail space that surrounded exposed VBP20 vapor barrier.
In 2023, H&H was contracted to oversee the repairs and completion of the VIMS at Commercial
Space 01 during tenant upfit as a taproom and social club called Bulldog Taproom (Bulldog).
The Bulldog upfit activities began in April 2023 and were recently completed. A discussion of
the Bulldog upfit activities and associated VIMS inspections is provided in Section 2.0, an
overview of VIMS influence testing is provided in Section 3.0, and a summary and conclusions
are provided in Section 4.0.

2.0 Tenant Upfit Inspections

Tenant upfit activities were conducted at the Bulldog retail space, which is located in the western
portion of the southern building. As outlined in the VIMP and VIMS completion reports, the
VIMS in the Bulldog space includes a permeable gravel layer, sub-slab vapor collection piping, a
vapor barrier (VBP20), riser piping, and wind-driven turbine ventilators. A drawing depicting
the layout of the VIMS and the system specifications and details is provided as Figure 3
(Attachment A), and product specifications for the VIMS components are included in
Attachment B. As part of the upfit activities, the existing vapor barrier located inside the ribbon
slab was cut to allow for utility installations. Additionally, several narrow trenches were
installed within the concrete ribbon slab for installation of utilities which required temporary
removal of the vapor barrier at these locations.

Between April 2023 and August 2023, H&H conducted inspections under direction of a North
Carolina (NC) Professional Engineer (PE) during various phases of construction to verify that
the VIMS in Commercial Space 01 was installed in accordance with the DEQ-approved VIMP.
During the upfit activities, minor modifications to the VIMS vent piping were made during the
tenant upfit activities to accommodate shallow footings and utilities present in the upfit design.

(NCBP 22076-18-060)_11-2-23.doc
The modifications were limited to shifting a small section of the sub-slab horizontal VIMS
piping in the subgrade gravel to accommodate the building layout. No modifications were made
to the pipe size or vertical piping. H&H completed the following VIMS inspections during the
Bulldog upfit:

 visual inspection of the base gravel and VIMS vent piping prior to installation of the
vapor barrier;
 visual inspection of the vapor barrier prior to the concrete pour; and
 visual inspection of the sealant at the joints between the original and repaired concrete.

After installation of the sub-grade utilities and before the concrete slab was poured, the sub-
grade VIMS components were repaired and restored in accordance with the DEQ-approved
VIMP. After installation and inspection of the gravel (washed #57 stone) and verification that
the vent pipes remained in good condition, VBP20 was replaced above the gravel layer and
sealed to the existing vapor barrier or concrete along the ribbon slab, when necessary, in
accordance with manufacturer installation instructions. Vertical utilities which penetrate the
vapor barrier were also sealed in accordance with VBP20 manufacturer installation instructions.
The concrete was then poured to complete the slabs in the retail space. Based on observations
made during the VIMS inspections, the VIMS was installed in general accordance with the
VIMP. Representative photographs from the upfit inspections are included as Attachment C.

When the building was first completed, the pour-back area of Commercial Space 01 contained a
total of three monitoring points, two temporary monitoring points (TMP-3 and TMP-4) located
in the footprint of the pourback area and a permanent monitoring point (MP-4). Access to the
MP-4 location is located in the adjacent hallway/lobby to the southeast of Bulldog. The
monitoring points were constructed with 2-inch diameter SCH 40 PVC to conduct effectiveness
testing including vacuum influence measurements and for collection of sub-slab vapor samples
for laboratory analysis. During upfit activities, H&H discovered an additional monitoring point
was installed along the ribbon slab of the pour-back space and was incorrectly identified as MP-4
during initial VIMS influence testing (Section 3.0). H&H observed both monitoring points to be

(NCBP 22076-18-060)_11-2-23.doc
in good condition and both are connected directly to the sub-slab gravel based on the results of
an influence test (Section 3.0). Due to its proximity to MP-4, this monitoring point is hereon
referred to as MP-4A, and both locations are depicted in Figure 3 (Attachment A).

3.0 VIMS Influence Testing

On August 4 and October 17, 2023, H&H completed influence testing in the Bulldog upfit space
to evaluate system sub-slab communication and to confirm that adequate vacuum can be
obtained should an active depressurization system be needed in the future. DEQ considers
4 Pascals (Pa), or 0.016 inches of water column (in-WC) differential pressure the minimum
vacuum needed for an active depressurization system to effectively treat potential vapor
intrusion.

To perform the influence testing, H&H connected electric fans with variable vacuum settings to
the vertical riser piping to model an active depressurization system. Differential pressure
measurements were collected at the vacuum monitoring points using a Dwyer series 475 Mark
III Digital manometer (capable of measuring to 0.001 in-WC or 0.25 Pa) to establish baseline
conditions prior to use of the electric fans. The electric fans were then turned on and differential
pressure measurements were collected at each monitoring point over varied time intervals. The
locations of the monitoring points are shown in Figure 3 (Attachment A), and the influence test
data table is included in Attachment D. Results of the influence tests indicated sufficient
differential pressure (ranging from -0.810 to -0.944 in-WC) in each of the temporary and
permanent monitoring points.

As discussed in Section 3.0, the construction of the pour-back space included two temporary
monitoring points. After the completion of the effectiveness testing on August 4, 2023, and prior
to completion of the upfit, the temporary monitoring points were abandoned with concrete and
finished in a similar fashion to surrounding floors. The monitoring point MP-4A (Section 2.0) is
located in a bathroom and therefore did not need to be abandoned. Therefore, both MP-4 and
MP-4A are both considered permanent monitoring points that represent the sub-slab space of the
Bulldog retail space.

4.0 Summary and Conclusions

In accordance with the DEQ-approved VIMP, H&H has completed upfit inspection of the pour-
back space in Commercial Space 01 (Bulldog) in the southern building of The Winston mixed-
use development on the western part of the West Boulevard Brownfields Property (Brownfields
Project No. 22076-18-060) located in Charlotte, Mecklenburg County.

The VIMS installation in the retail pour-back upfit consists of a passive sub-slab
depressurization system with vertical extraction piping to the roof connected to wind-driven
turbine ventilators. During upfit of the pour-back area, the vapor barrier was cut to allow for
utility installations below the VIMS. After installation of the utilities and before the concrete
slab was poured, the VIMS components were repaired and restored in accordance with the DEQ-
approved VIMP. H&H personnel, under the direction of a North Carolina-licensed Professional
Engineer, conducted inspections during each stage of repair. Results of the upfit inspections
indicate that the VIMS was installed in general accordance with the DEQ-approved VIMP.
Upon completion of the concrete slab in the retail space, VIMS influence testing confirmed
sufficient communication of the sub-slab system and that adequate vacuum can be obtained from
active depressurization in the Bulldog space.

Following Bulldog upfit activities, the second post-occupancy sampling event was performed in
September 2023. Results of the September 2023 post-occupancy sampling event will be reported
under separate cover.

VAPORBLOCK® PLUS™ PLACEMENT
1.1. Level and tamp or roll granular base as specified. A base for a gas-reduction system may require a 4” to 6” gas permeable layer of clean coarse aggregate as specified by your architectural or structural drawings after installation of the recommended gas collection system. In this situation, a cushion layer consisting of a non-woven geotextile fabric placed directly under VaporBlock® Plus™ will help protect the barrier from damage due to possible sharp coarse aggregate.
1.2. Unroll VaporBlock® Plus™ running the longest dimension parallel with the direction of the pour and pull open all folds to full width. (Fig. 1)
1.3. Lap VaporBlock® Plus™ over the footings and seal with Raven Butyl Seal tape at the footing-wall connection. Prime concrete surfaces, when necessary, and assure they are dry and clean prior to applying Raven Butyl Seal Tape. Apply even and firm pressure with a rubber roller. Overlap joints a minimum of 6” and seal overlap with 4” VaporSeal™ Tape. When used as a gas barrier, overlap joints a minimum of 12” and seal in-between overlap with an optional 2-sided Raven Butyl Seal Tape. Then seal with 4” VaporSeal™ Tape centered on the overlap seam.

1.4. Seal around all plumbing, conduit, support columns or other penetrations that come through the VaporBlock® Plus™ membrane.
1.4a. Method 1: Pipes four inches or smaller can be sealed with Raven VaporBoot Plus preformed pipe boots. VaporBoot Plus preformed pipe boots are formed in steps for 1”, 2”, 3” and 4” PVC pipe or IPS size and are sold in units of 12 per box (Fig. 3 & 5).
Pipe boots may also be fabricated from excess VaporBlock® Plus™ membrane (Fig. 4 & 6) and sealed with VaporBoot Tape or VaporSeal™ Tape (sold separately).
1.4b. Method 2: To fabricate pipe boots from VaporBlock® Plus™ excess material (see Fig. 4 & 6 for A-F):
A) Cut a square large enough to overlap 12” in all directions.
B) Mark where to cut opening on the center of the square and cut four to eight slices about 3/8” less than the diameter of the pipe.
C) Force the square over the pipe leaving the tightly stretched cut area around the bottom of the pipe with approximately a 1/2” of the boot material running vertically up the pipe. (no more than a 1/2” of stretched boot material is recommended)
D) Once boot is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in between the two layers. Secure boot down firmly over the membrane taking care not to have any large folds or creases.
E) Use VaporBoot Tape or VaporSeal™ Tape to secure the boot to the
pipe.
VaporBoot Tape (option) – fold tape in half lengthwise, remove half of the release liner and wrap around the pipe allowing 1” extra for overlap sealing. Peel off the second half of the release liner and work the tape outward gradually forming a complete seal.
VaporSeal™ Tape (option) - Tape completely around pipe overlapping the VaporBlock® Plus™ square to create a tight seal against the pipe.
F) Complete the process by taping over the boot perimeter edge with VaporSeal™ Tape to create a monolithic membrane between the surface of the slab and gas/moisture sources below and at the slab perimeter. (Fig. 4 & 6)

1.5. Sealing side-by-side multiple penetrations (option 1);
A) Cut a patch large enough to overlap 12” in all directions (Fig. 7)
of penetrations.
B) Mark where to cut openings and cut four to eight slices about
3/8” less than the diameter of the penetration for each.
C) Force patch material over penetration to achieve a tight fit and
form a lip.
D) Once patch is positioned, seal the perimeter to the membrane
by applying 2-sided Raven Butyl Seal Tape in-between the two
layers. (Fig. 8)
E) After applying Raven Butyl Seal Tape between the patch and
membrane, tape around each of the penetrations and the patch
with VaporSeal™ 4” tape. (Fig. 9) For additional protection apply
POUR-N-SEAL™ or an acceptable polyurethane elastomeric
sealant around the penetrations. (Fig. 10)

Cut a patch large enough to overlap 12” in all directions and slide over penetrations (Make openings as tight as possible.)
Once the overlay patch is positioned, seal the perimeter to the membrane by applying 2-sided Raven Butyl Seal Tape in-between the two layers.
After applying Raven Butyl Seal Tapebetween the patch and membrane, tape around the perimeter of the penetration and the patch with VaporSeal™ 4” Tape.
For additional protection apply POUR-N-SEAL™ or an acceptable polyurethane elastomeric sealant around the penetrations.

1.6. POUR-N-SEAL™ method of sealing side-by-side multiple penetrations (option 2);
A) Install the vapor barrier as closely as possible to pipe penetrations to minimize the amount of POUR-N-SEAL™ necessary to seal around all penetrations.
B) Once barrier is in place, remove soil or other particles with a dry cloth or a fine broom to allow for improved adhesion to the POUR-N-SEAL™ liquid.
C) Create a dam around the penetration area approximately 2” away from the pipe or other vertical penetrations by removing the release liner from the back of a 1” weather stripping foam and adhere to the vapor barrier. Form a complete circle to contain the POUR-N-SEAL™ materials (Fig. 11).
D) Once mixed, pour contents around the pipe penetrations. If needed, a brush or a flat wooden stick can be used to direct the sealant completely around penetrations creating a complete seal (Fig. 12-13).
E) DO NOT leave excess POUR-N-SEAL™ in plastic container for longer than the time it takes to pour sealant.

VAPORBLOCK® PLUS™ REPAIR INSTRUCTIONS
1.7. Proper installation requires all holes and openings are repaired prior
to placing concrete. When patching small holes, simply cut a 12” long
piece of 12” wide VaporSeal™ tape. Remove release liner and center
over the opening. Apply pressure to create a seal (Fig. 14-15).
1.8. When installing VaporBlock® Plus™ around pipe penetrations,
vertical columns, electrical ducts and other obstructions, you will
find it necessary to cut it to the nearest outside edge. This cut can
be easily sealed with 12” wide VaporSeal™ tape, by simply centering
it over the cut, 6” on either side. Once the tape is placed correctly,
apply pressure to assure a complete seal (Fig. 16).
Reminder Note: All holes or penetrations through the membrane will need
to be patched with 12” VaporSeal™ Tape.

2.1. When installing reinforcing steel and utilities, in addition to the
placement of concrete, take precaution to protect VaporBlock®
Plus™. Carelessness during installation can damage the most
puncture–resistant membrane. Sheets of plywood cushioned with
geotextile fabric temporarily placed on VaporBlock® Plus™ provide
for additional protection in high traffic areas including concrete
buggies.
2.2. Use only brick-type or chair-type reinforcing bar supports to protect
VaporBlock® Plus™ from puncture.
2.3. Avoid driving stakes through VaporBlock® Plus™. If this cannot be
avoided, each individual hole must be repaired per section 1.7.
2.4. To avoid penetrating VaporBlock® Plus™ when installing screed
supports, utilize non-penetrating support, such as the Mako®
Screed Support System (Fig. 17). Avoid driving stakes through
VaporBlock® Plus™. If this cannot be avoided, each individual hole
must be repaired per figures 14-15.
2.5. If a cushion or blotter layer is required in the design between
VaporBlock® Plus™ and the slab, additional care should be given if
sharp crushed rock is used. Washed rock will provide less chance of
damage during placement. Care must be taken to protect blotter layer
from precipitation before concrete is placed.
