About this file

This document is a Façade Condition Assessment Report prepared by Raymond Engineering-Georgia, Inc. for the Volusia County Facility Management, focusing on the S. James Foxman Justice Center located at 251 N Ridgewood Ave in Daytona Beach, Florida. The report, dated March 12, 2025, provides a comprehensive evaluation of the building's exterior brick façade and window systems, which were originally constructed in 1989. The assessment involved a limited visual inspection conducted on October 3, 2024, and a destructive observation of 9 probe locations on February 4, 2025, revealing significant deterioration in the building's exterior components.

The report identifies critical issues including severely corroded brick ties, improper drainage systems, saturated moisture behind the brick façade, and widespread deficiencies in window frames and sealants. Raymond Engineering recommends priority actions, including full replacement of approximately 28,813 square feet of brick façade, installation of proper weep holes and drainage systems, and complete replacement of the aluminum window systems. The estimated repairs involve ensuring compliance with current building codes, addressing air barriers, wall sheathing, expansion joints, shelf angles, and other critical building envelope components. The assessment suggests that these extensive repairs are necessary to prevent further structural deterioration and potential water intrusion issues.

S. JAMES FOXMAN JUSTICE CENTER

FACADE CONDITION ASSESSMENT REPORT

INTRODUCTION

At the request of Volusia County Facilities, Raymond Engineering-Georgia, Inc. (Raymond) performed a limited building façade condition assessment of the S. James Foxman Justice Center. The assessment was conducted on October 3rd, 2024. Raymond performed limited visual condition assessments of the façade/exterior cladding, and fenestration.

In addition, on February 4, 2025, a destructive observation of 9 probes locations was conducted, and the deficiencies found appear to be similar in nature.

Our overall findings are summarized below. Refer to the Appendices for the individual reports of the assessed building envelope components.

INVESTIGATIVE PROCEDURE

LIMITED VISUAL ASSESSMENT:

The scope of Raymond’s limited visual assessment and the destructive observation of probes work included, but was not limited to, performing a non-invasive visual condition assessment of the exterior façade. The limited visual assessment included an interior walkthrough of the building and visual observations at grade level to document the condition of the building’s exterior walls. Additionally, Raymond had discussions with facility personnel to obtain information regarding the building. The limited visual assessments involved the review of existing limited construction documents, industry standards, and manufacturer’s requirements. Magnification equipment, including telephoto camera lenses and drone, were utilized.

Conditions not subject to visual review (e.g., structural framing, concealed clips, etc.) are beyond the scope of this report.

EXECUTIVE SUMMARY

Record drawings provided by Volusia County Facilities indicate the building was constructed in 1989 and has an approximate total area of 59,586 SF. The three-story building is constructed of structural steel columns and girders, concrete floor system and steel and wood frame walls with a brick façade.

Selected windows on accessible elevations were assessed for evaluation of framing assembly, general installed condition, compliance with original design documents and details, operation performance.

13 Probes locations where brick was removed to observe conditions of installation of brick ties, wall sheathing, shelf angles, flashing and brick weep and drainage system.

FAÇADE CONDITION ASSESSMENT:

Limited Visual Assessment

Raymond observed the following:

1) Exterior Brick Wall System

In general, the brick façade appeared to be in poor condition and the deficiencies observed are typical around the entire building brick façade. The deficiencies on all façades are due to missing a proper drainage system, saturated moisture behind the

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 4 brick, and, in multiple cases, missing rope weep holes above and below windows and at the wall base. The missing weep holes do not allow drainage of moisture that accumulates in the wall cavity; this has resulted in wet brick mortar, algae stains, surface corrosion on window header supporting angles, and chalking and oxidation in the windows’ aluminum frame.

The probes indicated corrugated brick ties were installed. Per the Brick Institute of America (BIA) Technical Note # 44B, corrugated ties are typically used in low-rise, residential veneer over wood frame construction and are not recommended for construction incorporating brick veneer over steel studs, masonry-backed cavity walls, multi-wythe walls or grouted masonry walls.

Other masonry deficiencies observed were the fractured and missing brick face, bed mortar, and expansion joints on the miter corners of the building, where medium to wide size cracks, in addition to the lack of drainage or weep hole tubes throughout the building. At the miter corner, the sheathing has gaps allowing air to escape from the interior space (suggesting breach in air barrier) into the wall cavity.

The 30# asphalt-based air and weather barrier was installed with randomly spaced stapples, where detached vertical and horizontal laps allowed air and moisture to reach the gypsum-based wall sheathing. The staples show signs of corrosion.

Since the date of this field observation visit, the recent hurricanes (Helene and Milton) impacted the brick façade.

On the debris removed from the area impacted by recent hurricanes the brick ties showed severe corrosion, the ties did not form a 90-degree angle and did not appear to have the minimal embedment into the brick.

During the third site visit additional bricks were removed to observe flashing, sheathing conditions, and attachments of the brick supporting steel angles. In this case we observed that a WT steel beam was in place and a self-adhered membrane was installed as the flashing over the WT beam and approximately 3 brick courses over the wall sheathing and behind the #15 felt paper. Moisture was felt at touch on the wall sheathing. No corrosion on the steel studs, insulation in the wall cavity was dry

As a (Priority), Raymond recommends full replacement of the current brick façade with a new brick façade. Remove and replace all brick façades (approx. 28,813 SF), ensuring air barrier, wall sheathing, expansion joints, ties, shelf angles, through-wall flashings, sealants, backer rods, mortar dams, weeps, and accessories are installed to current building codes.

2) Aluminum Window System

In general, Raymond observed these assemblies to be deficient (functionally and aesthetically). The window frame does not have a drainage system, shrinking of the exterior neoprene gaskets has occurred creating voids in the corners and moisture penetrating between the frame joints is causing oxidation in the aluminum frame from inside out producing pitting and paint delamination.

The windows have sealants all around between the frame and brick wall; in many cases the sealant is fractured, allowing moisture and air leakage which could cause condensation in the interior with temperature differential.

Raymond recommends as (Priority) removal of all deteriorated windows and installation of a new window system per current building and energy codes. This new design will need to incorporate a new flashing system above window headers and windowsills. The design will need to be completed in conjunction with structural

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 5 calculations, brick supporting ledge angles, new brick ties replacement of sheathing and air and moisture barrier. Section of steel studs might need to be replace and any insulation found to be wed will need to be replaced.

3) Cement plaster stucco on East and West elevations and soffits.

The cement plaster stucco appeared to be in good condition. Raymond observed the paint was fading and chalking on the exterior. Raymond recommends as (Routine) cleaning and acrylic painting of the stucco surface.

OBSERVATIONS AND FINDINGS

Conditions were photo-documented and recorded using standard field assessment forms and elevation drawings developed for the facility. Our assessment procedures sought to capture the necessary information to develop a scope of work for the restoration of the exterior walls of the building.

(Refer to Elevations and Legends on Appendix A for location of deficiencies found on brick veneer wall and windows assemblies).

Exterior Brick Wall System Defects:

Refer to sketches on the following pages for defects found on brick masonry cavity wall.

Refer to Appendixes B and C for photographs.

Brick Ties:

Per building code and industry standards the masonry veneer shall be anchored to the supporting wall studs with corrosion-resistant metal ties embedded in mortar or grout and extending into the veneer a minimum of 11/2 inches, with not less than 5/8-inch mortar or grout cover to outside face. Per Brick Institute of America (BIA) Technical Note # 44B corrugated ties are typically used in low-rise, residential veneer over wood frame construction and are not recommended for construction incorporating brick veneer over steel studs, masonry-backed cavity walls, multi-wythe walls or grouted masonry walls.

Corrugated sheet metal ties shall be not less than No. 22 U.S. gage by 7/8 inch with end bent to form a 90-degree angle to form a hook. Each tie shall support not more than 2.67 square feet of wall area and shall be spaced not more than 32 inches on center horizontally and 24 inches on center vertically.

Observations:

Corrugated brick ties show severe corrosion. Corrugated brick ties are not installed in an “L” shape 90 degrees angle to allow for proper bearing of the brick and embedment into the brick mortar.

Obstructed Cavities:

Dark and wet brick mortar, algae stains, surface corrosion on window header supporting angles and in multiple locations efflorescence on brick surface. Dark horizontal mortar joints often indicate the cavity is not draining properly. Cavities are typically prevented from draining because of mortar droppings which occur when excessive mortar was allowed to drop behind the brick during construction.

Observations:

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 6

The deficiencies around the building all façades are due to missing a flashing system below or above the windows and at the wall base that do not allow drainage of moisture that accumulates in the wall cavity. Corrosion was observed on the steel angles supporting the brick header.

Weep Holes Missing:

A weep hole is a narrow tube or rope that runs through the vertical joint between bricks of the face wythe and connects the cavity with the exterior. Weeps can be vertical head joint typically spaced at 16” O.C. for tubes or wicks to 24” O.C. for open head joints. Weeps are part of the secondary line of defense in a masonry cavity wall system. Water which manages to infiltrate the face of the wythe is channeled through the cavity and drained away via the system of regularly spaced weep holes. Non-functioning weep holes or the lack of weep holes permit an unrelieved accumulation of water within the cavity, with potentially adverse consequences to the adjacent masonry construction, including cracking, bulging of brick, and corrosion of underlying steel structure.

Observations:

Except for a small section on the North and South façades weep holes were not observed throughout the building. The absence of weep holes above and below windows did not allow drainage of moisture that accumulates in the wall cavity creating water stains on mortar joints in multiple locations. Through-wall flashing was not found at wall base on all façades.

Cement plaster stucco on Walls soffits:

The cement plaster stucco failure is the state or condition in which the stucco system cannot meet its intended objective. Stucco failure processes often start with minor cracking leading to water intrusion and ultimately microbial growth and or damage to structural elements of the building.

Observations:

Raymond observed the paint fading out and light corrosion on exterior soffit edge below the brick wall. Raymond recommends repairing the soffit exterior joints and recoating the stucco wall/soffit. Verify a drainage plane is provided below the brick wall at stucco interface.

Efflorescence:

Efflorescence occurs when water containing dissolved salts is brought to the surface of masonry, the water evaporates, and the salts are left on the surface. The salt solutions may migrate across surfaces of masonry units, between the mortar and brick units, or through the pores of the mortar or brick units.

Observations:

At areas all around the building, efflorescence is occurring at spotted locations mainly below the windows cast stone sills. This indicates that moisture is infiltrating into the joints or transitions and dissolving the salts in the transition. Upon evaporation, the salt is deposited on the surface. In several cases, the efflorescence is running down the face of the brick. In these cases, water from outside makes its way through transitions such as open joints, openings in sealant, and openings in transition areas.

Windows – Exterior Sills and Header:

Most of the windows have precast concrete sills, except for the curtain wall windows. The window headers have a supporting steel angle that in many cases appears to have a ¾” gap at center point. At the West Elevation (main entrance) the curtain wall has a rowlock brick projected out approximately 1 3/8” from supporting WT steel member.

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 7

Observations:

Windows with sealed flashing above at supporting steel members and missing weep holes, wide cracks and horizontal expansion joints, other windows showed water and color stains window frame, surface and moderate corrosion on window frames and surface corrosion on supporting steel angles.

Routine - Recommended Repairs

Based on Raymond’s limited visual assessment, replacement, repairs and maintenance are recommended. The Owner should retain a professional to develop and oversee an appropriate design, repair and maintenance scope of work to address all items listed in this report.

Raymond recommends repairs under Immediate Action and Priority Action.

Raymond recommends the Owner take Priority Action to address the following deficiencies:

1. Brick Façade Replacement:

a. Remove and replace all brick façades (approx. 28,813 SF), ensuring air barrier, expansion joints, ties, shelf angles, through-wall flashings, sealants, backer rods, mortar dams, weeps, etc. are installed to current building codes.

Raymond recommends the Owner take Priority Action to address the following deficiencies:

2. Brick façade Repairs:

a. Most of the brick façade deficiencies observed could be attributed to lack of moisture draining out of cavity wall system. It is evident through improper flashing system installed without weep holes. In all locations where existing weep holes are missing/blocked, Raymond recommends installing new weep holes and cell vents within vertical joints at 24" O.C. This installation will permit water to drain out of the wall cavity and will promote free circulation of air within the cavity.

Remove three to four courses of brick masonry above window header angle/ ledge supporting the brick.

Clean cavity of all cement droppings.

Clean exposed steel surface and apply rust inhibiting coating to spandrel beam.

Install continuous shelf angle to support bricks at locations where shelf angle is not continuous.

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 9

Provide new flashing membrane.

Replace face bricks, installing weep holes at 24" O.C.

Remove two or three courses of brick below the shelf angle. Install compressible filler below shelf angle.

Provide weep system at brick/cast stone interface and at rowlock brick sills.

Install one vertical expansion joint down the full height of the brick façade on the South side of the building within two feet of the southwest corner.

Note: With this approach of spot repairs, periodic assessment of brick façade is recommended every six months to see any new deficiencies and repair deficient conditions. Spot repair of brick façade option may be an aesthetic concern. New brick color matching with existing adjacent brick will be challenging.

3. Signs of water infiltration:

a. Control and expansion joints on brick walls

Remove and replace as required.

b. Soffit edge and storefront aluminum window system on West and East façades

Repair or replace as required.

Spot crack required repairs for areas lower than 144 SF.

Rout out cracks to 1/4" – 1/2" depth and width.

Repair cracks with polymer modified, cementitious, low modulus, and non-sag repair mortar and paint to match existing.

c. Area required repairs larger than 144 SF. In addition to the Option A repairs, Raymond recommends the following be implemented to provide a full remediation of the stucco soffit areas:

Remove and replace entire area where cracks exceed areas larger than 144 SF.

Replace stucco, weather barrier and lath per ASTM 1063.

Where required, install a control joint at a maximum spacing in soffits or walls of 18 ft O.C. both horizontally and vertically enclosing an area no more than 144 SF. and paint to match existing.

4. Curtainwall and aluminum window system:

a. Remove and replace all windows, sealant all around including glazing perimeter per MFR.

Monitor the conditions annually under the guidance of a professional as time and exposure to the elements may cause change and deterioration.

Clean and seal to prevent water intrusion.

Raymond recommends the Owner take Routine Action to address the following deficiencies:

5. Corrosion repairs on access panels at exterior soffits, louvers and vents:

a. Corrosion repairs on access panels at exterior soffits, louvers and vents

Raymond recommends analyzing and repairing the localized areas of corrosion. If the steel is sound, sand to remove the corrosion and apply a protective coating. If corrosion is severe, remove and replace section of components as required to match existing.

APPENDIX D – GLOSSARY OF TERMS AND DEFINITIONS

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 45

A. Definition of Investigation Types

Hands-on Investigation: Close-up inspection from no further away than an arm’s length where the member or condition can be physically touched.

Visual Investigation: The investigation from a reasonable distance of a member or element where the initial determination of the condition can be made.

Invasive Investigations: Investigations where walls or elements are opened to allow for hands-on inspections to be made. Repairs are necessary to restore the wall or element.

B. Definition of Recommendations

Immediate:

3-6 Months Requires immediate action to repair the leak sites to prevent future and ongoing deterioration to the system or components and structural system. Replacement of a portion or all the system and damaged sheathing or decking and structural members is a priority.

Priority:

6-12 Months Conditions for which no immediate action may be required or for which immediate action has been completed, but further investigations, design, and implementation of interim or long-term repairs or replacement of the system should be undertaken on a priority basis, i.e., taking precedence over all other scheduled work.

Routine:

12-36 Months Conditions requiring further investigation or remedial work, which can be undertaken as part of a scheduled maintenance program, other scheduled project, or routine facility maintenance, depending on the action required.

C. Rating Criteria

Terms used to describe the condition of a building’s system or components are listed and defined below. When the term is applied to a system, this does not indicate that all elements of the system are in the same condition.

Excellent: As New Condition

Good: The system or components are sound and performs its function, although it shows signs of wear and may require some minor repairs, mostly routine.

Fair: The system or components are still performing adequately currently but needs priority and/or routine repair to prevent future deterioration and to restore it to good condition.

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 46

Poor: The system or components cannot be relied upon to continue to perform its original function without immediate and/or priority repair or replacement.

D. Investigation Terminology

The following terms may be used during investigations to describe the condition of structural members.

1. Steel Members

Corrosion: Minor; light surface rust.

Moderate Rust; that is loose and flaking with some pitting.

This scaling, or exfoliation, can be removed with some effort by use of a scraper or chipping hammer. Element exhibits measurable but not significant loss of area.

Severe-Heavy; stratified rust or rust scales with extensive pitting. Removal requires exerted effort and may require mechanical means. Significant loss of area.

Impacted Rust: Rust collected between two interfacing surfaces, usually two steel plates. Impacted rust can be minor, moderate, or severe as described above. Impacted rust can severely deform the steel members due to the expansive nature of rust.

Pitting: Formation of cavities due to corrosion. Minor, moderate, and severe pitting categories are used based upon depth and density of cavities.

Minor; Typically less than 1/4 inch diameter and 1/32 inch deep.

Moderate; 1/4 inch to 1/2 inch diameter and up to 1/8 inch deep.

Severe; Greater than 1/2 inch diameter and over 1/8 inch deep.

2. Concrete Members

Cracking: A separation into two or more parts with a space between the fractured concrete surfaces.

Hairline; Crack width less than 1/32 inch.

Fine; Crack width between 1/32 inch and 1/16 inch.

Medium; Crack width between 1/16 inch and 1/8 inch.

Wide; Crack width greater than 1/8 inch.

The above definitions for cracks can be modified, depending on the type of structural element. Other terminology, such as

CONYERS | CHARLESTON | CHRISTIANSBURG | GREER | ORLANDO | RALEIGH | RICHMOND | SAVANNAH | 47 map cracking, pattern cracking, etc., may be used as appropriate.

Efflorescence: A white deposit caused by crystallization of soluble salts brought to the surface by moisture leaching through concrete.

Delamination: A layered separation of the concrete. When a delaminated area of concrete is struck (sounded) with a hammer; a hollow sound will be emitted.

Leaching: The dissolution and washing away of the calcium hydroxide in concrete. The moisture enters the concrete through exposed cracks in the surface.

Spall: A roughly circular, oval, or elongated depression in the surface of a concrete element caused by separation of a portion of the surface concrete.

Small: (Pop-out) Less than 6 inches in diameter and 1 inch deep.

Medium: Between 6 inches and 12 inches in diameter and up to 2 inches deep.

Large: Over 12 inches in diameter and any depth.

Scaling:…
