PROJECT INFORMATION

The Old Bay County Juvenile Courthouse building project site is located at 533 East 11th Street in Panama City, Florida. The structure was believed to have been constructed between 2008-2010 and consists of a multi-story facility encompassing approximately 25,000 square feet. The building underwent major repairs as a result of Hurricane Michael that impacted the area in 2018. The contract for storm repairs was believed to have been approved on April 16, 2019.

The main building’s primary structural system appeared to consist of a steel framed building structure supported by concrete slab on grade. The exterior wall assembly appeared to be comprised of concrete masonry unit (CMU) block walls with a combination of brick masonry veneer and EIFS finishes. EIFS were observed at the main entrance, and along the 2nd story upper-level wall sections located on the north, east and west elevations. Approximately three-foot by ten-foot precast wall panels are located on the 1st level along the north, south, east and west elevations supporting the masonry brick veneer walls.

Fenestrations consisted primarily of storefront window assemblies that were installed on the 2nd level along the north, east and west elevations with a curtain wall system and storefront doors installed at the south elevation main entrance. Two overhead garage door units were located at that sally port's east and west entrance, and the remaining fenestration openings appeared to be hollow metal frames and doors which were located on the first level of mechanical, electrical and entry/exit doors of the main building.

The primary roof system consists of a standing seam metal roof assembly. The roof assembly is set at two elevation heights. The higher elevation section is located in the center of the building covering the 2nd level offices and the two lower roof elevations are located on the east and west side of the building. Roof parapet walls are part of the lower roof sections and are located on the southeast and southwest elevations.

The information presented herein is intended to document general prevailing conditions rather than provide an as-built description. The building had been reportedly experiencing moisture intrusion since the repairs that took place post hurricane Michael, and NOVA was unaware of any remediation efforts that had been made to resolve the reported moisture intrusion issues.

Property access was provided by Bay County facilities/engineering group.

SCOPE OF SERVICES

NOVA performed a site visit to visually assess the roof conditions. A large percentage of the interior walls and acoustical ceiling tiles were removed to allow for observation and scanning.

No destructive investigation was performed as part of this scope.

The intent of this assessment was to review and evaluate the roof systems for possible moisture intrusion. Our observations will not include any other building components.

NOVA proposes to provide the following services:

▪ Review and evaluate documents and information provided by client and facility personnel.

▪ Interviews with key client and site personnel to obtain information regarding the exterior facade and roof system construction and performance.

▪ Visual observation of readily accessible components of the subject and associated interiors and roof systems. Where appropriate, observations and notes will be made concerning:

◦ General appearance and surface conditions regarding moisture resistance capabilities.

◦ Component characteristics and conditions. General drainage characteristics. Roof components including flashings, counter flashing, seams, ridges, valleys and copings.

In addition to the visual observations, we performed the forensic field testing as described below:

NOVA performed forensic water infiltration testing at isolated areas identified as suspect determined by our field staff or identified by the client as well as staff/building personnel of suspected or known sources of moisture intrusion in general accordance with a modified version ASTM E 2128-12, “Standard Guide for Evaluating Water Leakage of Building Envelopes”.

The test method consists of and references various water infiltration test methods including AAMA 501.2. This modified testing was conducted utilizing a Type B-25,#6.030 brass nozzle with a ½” FPT designated as the “Rain Wand” manufactured by RM Group, or similar. The test method consists of spraying water onto the test area at a regulated nozzle pressure and at a controlled distance from the test specimen. The nozzle in conjunction with a control valve and pressure gauge regulates the pressure between 30-35 psi. The stream of water from the nozzle is directed at an angle perpendicular to the test area while being moved back and forth in a parallel direction with the nozzle approximately one foot (1’) away from the test area specimen.

The designated test area shall be divided and evaluated in sections as needed to assess is moisture intrusion is occurring. Each section of the test areas shall be evaluated by slowly moving the nozzle back and forth over the test specimen. Working from the exterior, the test specimen shall be selectively wetted, progressing from the lowest horizontal component, then

Test areas include NOVA selected components, as determined by NOVA field personnel. Test areas may include roof transitions, flashing, counter flashing, seams, ridges, valleys and copings.

NOVA performed spot Infrared Thermography at select building interior roof deck areas to assist in discovering possible moisture intrusion.

ROOF MOISTURE INTRUSION ASSESSMENT

Standing Seam Metal Roof

The Standing Seam Metal roof consists of a steep-sloped metal roof assemblies listed as a 3:12 pitch on the field drawings. The roof system appeared to consist of metal decking over steel building roof framing (I-Beams and steel purlins). There was one-layer polyisocyanurate insulation board (approximately 2.20 inch), and 1/2 to 5/8 inch cover board with a asphalt type underlayment membrane. The insulation and cover board appeared to have been mechanically fastened with typical roofing insulation fasteners. Typical standing seam components were observed (Ridge/Hip caps, Z-closures, Edge flashings/Dip edge metal, Valley metal, and metal roofing style penetration boots. NOVA was not able to observe any of the metal roofing standing seam fastening clips or lay-out, as they were hidden.

The roof assembly has a gutter system installed on the high roof along the west and east roof edge with downspouts discharging water to the lower roof sections. The lower roof sections also have gutter system installed located on the east and west roof edge. The gutter downspouts drained into an internal drainage system possible connected to the city sanitary drainage system.

CONCLUSIONS

ROOF

Standing Seam Roof (low roof area) East Elevation

The parapet wall has a brick veneer facade on the outside and the inner side of the parapet wall is comprised of standing seam metal wall panels. The top of the parapet wall has a brick masonry cap course, and a gravel stop style metal flashing. The metal flashing extends unto the top of brick approximately 4 to 5 inches and also terminates approximately 8-10 inches over metal wall panels located on the roof side (inside) of the parapet wall. The sealant detail along the metal flashing leg that terminates on the top of the brick cap course was deteriorated and multiple voids were observed in the sealant joint. Mortar joints at the top of the brick cap course also were deteriorated and missing mortar was observed. While performing the moisture intrusion testing, at the top of the parapet wall, leaks were observed in the women's restroom and moisture intrusion occurred. When testing was performed along the (inside) portion of the parapet wall at its base along the south elevation and also along the east elevation at the roof termination (headwall flashing) at EIFS wall, leaks also occurred. The moisture intrusion that was observed in both the women's and men's restroom at head of wall along the south elevation, and moisture intrusion was observed at Vestibule 117 and Courtroom 1.

The typical Z-closure metal that was installed at the top of the metal roofing panels is a typical detail where metal roofing panels terminate at walls and along ridges and rakes. Also, above the Z-closure detail is a headwall flashing detail that is installed and it also is a standard detail.

Based on the various leaks that were reported and also observed while performing the moisture intrusion testing, it appears that there could be multiple conditions that allowed the moisture intrusion.

1. The first condition is related to the top of the parapet wall, where deteriorated sealant at flashing and open voids in mortar joints was observed and tested. While testing this condition moisture enters into the wall cavity, and the moisture migrates into the interior of the building possible due to a deficient vapor barrier installation at top of wall.

2. The second condition that could be allowing moisture intrusion appears to be related to deficient Z-closures and deficient headwall flashing. The Z-closure's butyl tape is disbonded at multiple Z-closures and there is no a secondary sealant bead applied up the metal panel rib at the notched Z-closure metal. The secondary sealant bead may also be missing behind the Z-closure. Proper sealant details may have not been performed at roof headwall flashing at seams and lap slices along with other metal flashing terminations that appeared to have poor sealant details and deteriorated sealants.

3. The third condition is that the roofing underlayment may have not been properly terminated up wall substrate and could have open voids in the membrane at overlaps and seams. Being that this roof assembly is not considered a steep slope roof due to the pitch of 1:12 as shown in the drawings and being that this area is a high wind zone region its required that proper underlayment details must be followed per NRCA and the Florida Building code.

Standing Seam Roof (low roof area) West Elevation

The west elevation low roof area is very similar to the east elevation low roof area. This roof area has a similar parapet wall make up and flashing details. However the parapet wall flashing did not extend on to the top of the brick cap instead it terminated approximately 4" below the top of brick on the inside face above the metal panels. An L-style flashing capped the top of the metal wall panels at the parapet wall. Head of wall flashing with Z-closures were typical as observed on the east low roof and appeared to have been installed in similar fashion. Leaks were observed while testing the Z-closures and head of wall flashing details along the west elevation at the roof to wall transition starting at the sally port and continuing along the west wall. Moisture intrusion occurred and was observed in the prisoner containment area and other spaces like the corridor and chase as listed in the floor plan drawings. it appears as previously observed that the moisture intrusion is occurring as listed.

1. Deficient Z-closures and deficient head of wall flashing. The Z-closure's butyl tape is disbonded at multiple Z-closures and there is no a secondary sealant bead applied up the metal panel rib at the notched Z-closure metal. The secondary sealant bead may also be missing behind the Z-closure. Proper sealant details may have not been performed at roof head of wall flashing at seams and lap slices along with metal flashing terminations that appeared to have poor sealant details and deteriorated sealants.

2. The roofing underlayment may have not been properly terminated up wall substrate and open voids in the membrane at overlaps and seams may be possible. Being that this roof assembly is not considered a steep slope roof due to the pitch of 1:12 as shown in the drawings and being that this area is a high wind zone region, it's required that proper underlayment details must be followed per NRCA and the Florida Building code.

High Area Standing Seam Roof Middle Section

Overall, the locking standing seam metal roof panels appeared to be in fairly good condition, along with the ridge caps and roof valley flashings. Moisture intrusion was not observed as water shed properly off the roof assembly. However, when Z-closures were tested at the roof peak, moisture intrusion was observed. Z-closures generally are set in butyl tape and the back side of the Z-Closure would be sealed with a compatible sealant along with Z-closure cut-outs around standing seam ribs. This detail is generally shown in most metal roofing installation

Also, the top of the metal roofing panels should have been boxed in and should have a proper 90 to 45 degree turned-up bend prior to the Z-closures properly being installed and attached. Based on the moisture intrusion that occurred while testing, it appears that the Z-closure installation is deficient and possibly the top of metal roof panels may also be deficient.

NOVA observed that sealant was installed at the roof peak, which appeared to be a type of remediation to correct the deficiency. However, this approach was unsuccessful as a result of poor installation.

Observed deficiencies were limited to minor priority items, including debris on the roof surface and localized surface coat deterioration/mineral loss. While these items do not necessarily indicate active leakage based on visual observation alone, continued mineral loss can reduce the protective surfacing over time and should be monitored and maintained to limit progressive wear and preserve long-term performance.

These conclusions are based on visual observations at the time of the site visit. The membrane type and underlying assembly components were not field-verified. Where corrective work is performed, contractor verification of existing conditions and compatibility with the existing roof system is recommended prior to repair

RECOMMENDATIONS

ROOF

Standing Seam Metal Roof

Minor condition recommendations

• Check HVAC mechanical vents and add the required fastener.

• Remove any loose debris from off roof areas.

• Clean metal panels that showed staining with roofing manufacturer approved cleaners.

Moderate condition recommendations

• Reattach gutter downspout at low roof east elevation.

• Rework or replace penetration boots and add clamping rings per manufacturer's specifications.

• Refasten and properly seal loose metal roofing components.

• Remove and reseal sealant details at metal flashing on top of the parapet wall at the low roof east and west elevation.

• Or replace parapet wall flashing with coping cap metal.

• Remediate gutter assemblies so that proper drainage is achieved.

Severe condition recommendations

• Remove and reinstall Z-closure metal and headwall flashing at areas that apply. Install per roofing manufacture details.

• Or perform sealant details at Z-closures and headwall flashing to seal all open voids in lieu of removal of the Z-closure. Manufactured recommended sealants should only be used.

• Check roofing underlayment for deficiencies. However, this could only be done by removing roofing panels.

• Remove ridge cap at roof peak (high roof) and reinstall Z-closures per manufacturer's details.

• Repair damaged metal decking at peak (high roof) and low roof east elevation (southeast corner).

LIMITATIONS

NOVA’s assessment, observations and/or tests reported herein are in no way a guarantee of deficient-free construction, nor do they indicate the only areas of potential deficient construction or failing components which may now, or in the future, contribute to moisture intrusion. NOVA did not perform a “hands-on” assessment of every portion of the building enclosure and testing was not performed on every construction component situation (i.e., joint, deficiency, or penetration or other areas) where moisture intrusion may occur. NOVA performed testing on areas identified by our staff or on-site personnel/client representative deemed as a potential avenue for moisture intrusion.

NOVA is not responsible for any damage resulting from our assessment and testing or the use of rented equipment. Being that part of our scope involved forensic moisture infiltration testing, moisture intrusion through the exterior façade affecting interior construction components was expected. NOVA’s evaluation is not a code compliance survey, nor an As-Built Drawing investigation. NOVA’s provided recommendations should not be considered a design document. Any revisions made to the findings enumerated in this report should be brought to the attention of NOVA. If deviations from notated construction or conditions are encountered during remedial applications, NOVA requires notification.

The results and observations presented in this report are time-dependent and as such conditions may have changed since the scope of services was performed. NOVA performed this Scope of Services, which is limited to the specific focus outlined. NOVA’s assessment and recommendations represent our professional opinion only and are based solely on the conditions observed from accessible areas during the site visits.

NOVA was not contracted to provide investigative services to detect the presence of mold or other biological contaminants in or around the building. Client acknowledges that these contaminants/ contamination are ubiquitous to the environment with amplification occurring when the building materials are impacted by moisture. As such, NOVA cannot and shall not be held responsible for the occurrence of contaminated amplification.
