12. Arden has substantially completed the rough-in for the under-seat displacement ventilation at the auditorium, and
the stub ups have been sealed to keep water out (see photo).
13. Building earthwork: Robert B. Our is continuing to backfill underslab utilities. RBO has started to lay crushed
stone for the slab installation at area B.
DISCREPANCIES, SPECIAL INSTRUCTIONS
22301. Misc envelope issues: PE met with Beacon, CB and PMA to discuss the following:
REPORT BY: ABH Page 2 of 4
(a) Termination of sheathing to foundation. Given unavailability of foil-faced polyiso, per PE detail, it was
agreed to bridge the horizontal gap behind the PCC base (where the rigid insulation edge is visible)
with an added layer of AVB-wrapped sheathing, and to strip that in at the upper and lower edges in
order to completely seal the wall base and the gap. PE to mark up on Beacon shop drawings.
(b) Membrane sill pan detail at windows. It was agreed to seal the windows as per the mockup, with a
secondary sealant joint all around the window on the interior side, in lieu of the membrane sill pan
and the turned up angle. Beacon has already installed the membrane sill pan at some windows, and
those will be left. PE to issue detail revision in Bulletin 25.
(c) Thru-wall Metal flashing at PCC sills. It was jointly agreed to omit the metal sill flashing under the
PCC sills at the typical windows in brick and to instead strip the bent plate into the AVB and leave it at
that. RJK signed off on this change per per email from Matt Carleton to A. Hazelton of 12/23. PE will
mark up on Beacon’s shop drawings.
21601. (from the 12-16 site report). ACM to brick joint (at gym): CB pointed out to PE that the face of the ACM on
the mockup is going to align with the back of the brick, which does not allow for a proper caulk seal. (on the
building itself this condition occurs twice at each of the corners on the east side of the gymnasium.) Update:
in an email to CB dated 12-17, PE issued a detail that modifies the trim on the ACM so that it can be properly
caulked-see below. CB to coordinate with Lymo—This item is being closed out.
21602. (from the 12-16 site report) Termination bar question: Beacon questioned the “roofing style” term bar that
was submitted and approved for fastening the thru-wall metal flashing to the face of the back up wall. It was
agreed to go with a flat term bar instead (Lighthouse to resubmit term bar). Update: Lighthouse resubmitted a
flat term bar and PE approved it. This item is being closed out.
21603. (From the 12-16 site report) OF scuppers: Harold bros has installed the originally-specified ‘lamb’s tounge’
scuppers at the overflow outlets high on the building, in spite of revised (Bulletin 14) detail, which called for
changing to a square one. Update: scuppers have not been changed out
12401. (From 11-24 site report): Sunshade outrigger discrepancies: Update: It was observed that in at least one
case there is an outrigger that is fully in the RO (NE corner, building C, level 2-- see photo). PE advised
Commodore that this needs to be moved so that the window can be installed and sealed properly.

Work Observed/Procedure
• Air and Vapor Barrier Membrane (AVB) Installation
• Roofing Installation - Area Designated as Part C
Observations
• Georgia Pacific DensGlass sheathing is being installed to steel stud infill framing on the first floor areas of
the building designated as Part D. (Figure 1)
• At Part D, south and north elevations, Gridlines D1-D6, GCP Perm-A-Barrier Aluminum AVB was installed
by Beacon Waterproofing and Restoration Inc. (Beacon). Primer/adhesive was applied to the DensGlass
Sheathing prior to RJK’s arrival on site. The membrane was installed in a water shedding fashion, with a
minimum 2-inch side lap and 10-inch lap around outside corners. Beacon rolled in the membrane utilizing a
silicone roller, per the manufacturer’s requirements. The membrane was extended onto the underside of the
wood nailer on the parapet wall. Strips were installed along the parapet nailer for proper roof to AVB
integration. (Figures 2 - 6)
• Sealant was applied at multiple wall penetrations following installation of AVB membrane per the
manufacturer’s requirements. Sealant is also applied to end sheet laps. (Figures 7, 8)
• At window rough openings a strip of AVB was installed extending 3-inches past the jamb and 3-inches onto
the exterior sheathing. The horizontal field sheets were run into the jambs in water shedding fashion. A
head strip was then installed lapping over the jamb strips, as required. (Figure 9 - 12)
• Sika Sarnafil Vapor Retarder SA 31 was installed onto the steel roof deck prior to RJK’s arrival on site. The
membrane was rolled in utilizing a 100-pound roller, per the manufacturer’s requirements. (Figure 13, 14)
• Sika Sarnafil Sarnatherm CG polyisocyanurate insulation was installed, loose laid over the vapor retarder in
two layers with offsets between rows and layers, as required. (Figure 15)

• Packaged and installed polyisocyanurate insulation was tested for moisture content utilizing a Delmhorst
BD-2100 Moisture Meter on the Reference Scale. Multiple tests were taken resulting in “0” on the reference
scale for all that were not visibly wetted. (Figure 17)
• Sika Sarnafil Sarnatherm High Density cover board was installed over insulation with the following field
fastening pattern: 16 plates and fasteners per 4 foot by 8 foot board, perimeter fastening pattern 24 plates
and fasteners per 4 foot by 8 foot board, and corner fastening pattern 32 plates and fasteners per 4 foot by 8
foot board, as required in the Sika assembly letter. (Figure 22 - 24)
• Sika Sarnacol-2170 VC Adhesive was roller applied to the cover board and allowed to flash off prior to
adhesion of the membrane, as required. (Figure 25)
• The Sika Sarnafil G 410-80 EnergySmart PVC Roof Membrane was cut to size and was allowed time to
relax prior to adhesion. Sika Sarnacol-2170 VC Adhesive was then roller applied to the back of the
membrane, and, immediately, the membrane was rolled onto the coverboard and rolled in utilizing a 100-
pound roller, per the manufacturer’s requirements. (Figure 26 - 28)
• Polyvinyl chloride (PVC) base flashing was installed at the parapet walls, set in Sika Sarnacol-2170 VC
Adhesive and rolled in utilizing silicone rollers per the manufacturer’s requirements. (Figure 29 - 31)
• The PVC roof membrane is lapped over the top of the parapet and affixed to the exterior face of the parapet
wall, as required. (Figure 32)
Discussions
AVB Installation
2.1 Rough Opening Detailing - Part D North and South Elevations - Installed AVB at rough openings does not
match the manufacturer’s details. Per GCP, the sill strip is to extend 3-inches up the jamb on the interior of
the rough opening and 3-inches past the jamb on the vertical wall. Likewise, the jamb strips are to extend 3-
inches past the head and sill on the vertical wall 3 -inches and extend 3-inches onto the sill and head at the
interior planes of the rough opening. The head strip should then lap 3-inches past the jamb on the vertical
wall and 3-inches down the jamb on the interior plane of the rough opening. (Figures 9 - 12)
Roofing Installation
2.2 Insulation Offset - Part D Roof - Polyisocyanurate insulation is staggered 8-inches to 10-inches between
layers. Sika Sarnafil requires a minimum offset of 12-inches between layers. (Figure 16)
2.3 Wetted Polyisocyanurate Insulation - Part D Roof - Multiple insulation boards were observed with wet areas.
The boards were tested for moisture content utilizing a Delmhorst BD-2100 Moisture Meter on the
Reference Scale resulting in elevated readings above “85”. (Figures 18 - 20)
2.4 Upside Down Insulation - Part D Roof - Multiple insulation boards were laid out with the bottom facing up.
Text on the board depicts “This Side Down”. Per discussion with Craig Nichols (Sika Sarnafil) on the
phone, it is preferred installation to follow the text though it should not affect the performance. (Figure 15,
21)

Yarmouth, MA
On Thursday, December 23, 2021, our office visited the job site to observe the construction progress for
the Dennis Yarmouth Intermediate Middle School. The Construction trades working this day included
concrete, masonry, cold-form, plumbing, electrical, and site contractors. During the visit, I spoke with
representatives from Commodore Builders and walked the site with Andy Hazelton.
Building earthwork continues with the installation of stone and backfilling of under slab utilities in areas
A, with stone being placed in area B.
Steel erection is substantially complete. The cold-form metal framing in areas D and C is in progress.
Miscellaneous steel is ongoing with the installation of stairs and railings.
The concrete slab-on-grade in the Gym is placed, and the under-slab insulation is being installed in area
B. The elevated concrete slab is placed in area B, and the auditorium stage decking is now installed.
Spray applied fireproofing has been installed on the columns and beams in the exterior walls. It was
noted that only the structural columns and beams require protection. The diagonal bracing and exterior
wind frames around the windows do not require protection. The scope was reviewed with the site
superintendent, Paul Genereux.
Detailing of the masonry work at the Gym was reviewed with Paul Genereux and Lighthouse Masonry
field superintendent Mike Cabral. Masonry work is progressing at the elevator shafts. Winter protection
methods are employed with temporary enclosures.
In general, the work observed appears in conformance with standard industry practice. Other than the
items noted above, there were no apparent deficiencies noted. However, there are open items on the
inspection log for deficiencies or incomplete items, and some of these items require our review. We
have reviewed the open items and recommend the following.
There are several low break results for the concrete tests. Non-Compliance Result (NCR) numbers 1
through 15 have been reviewed, and the results are acceptable for the design. The results of NCR ID#-17
are acceptable. The concrete tested in NCR ID#-17 was supplied at a higher design mix strength to allow
the design strength of 3,500 psi to be met sooner for setting steel.

The Floor Flatness criteria were not met on the suspended slab in Area D as noted in NCR ID#-16. The
overall value as measured is acceptable. The measured local value is lower than the specified value; this
may require repair before installing the floor finishes. It is my understanding that Commodore is aware
of this condition and is taking appropriate measures to meet the required level of finish for the flooring.
The steel inspection report from 12/16/21 notes incomplete compliance with certification and welding
procedures. These documents shall be provided to the testing lab for a complete review and record.
The inspection of the cold-formed metal framing has noted incomplete items and non-compliance with
screw connections. The deligated design engineer for the cold-formed metal framing will need to review
the non-compliance items.
The concrete testing report, lab log # 17282, indicates a low break for the concrete placed in the metal
pan stairs in area D. There appears to be nothing unusual in the testing report data, but the 28-day
break is well short of the supplied compressive strength of 4,000 psi. We would recommend a response
from the installing contractor and concrete supplier to verify the concrete proportions. The 56-day
break will be performed on 1/13/22, and we will review the stairs during our next site visit.
Respectfully,
