OVERVIEW
Critical Façade Examination for Existing Buildings
Exterior walls and building façades are exposed to weather, moisture, temperature changes and long-term deterioration that can affect both appearance and structural performance.
Anax Engineering provides critical façade examinations and condition assessments for Chicago buildings subject to ongoing exterior-wall inspection requirements.
Our work combines close-up visual examination, documentation of observed conditions and structural engineering judgment to identify areas of deterioration, distress or unsafe conditions and to support appropriate repair and maintenance decisions.
Evaluating Façade Conditions in the Field
Façade examination requires understanding both the visible exterior condition and the structural systems supporting the enclosure.
Close-Up Examination — Review accessible façade areas from swing stages, lifts or other means of access to document deterioration, cracking, displacement and other visible conditions.
Structural Components — Evaluate exposed or accessible masonry, steel, concrete, lintels, shelf angles, anchorage and other façade-support components where relevant.
Condition Documentation — Record representative observations, photographs and locations of distress to support the engineering assessment and final report.
Repair Priorities — Identify conditions requiring immediate attention, maintenance or longer-term repair planning based on observed severity and potential risk.
Typical Façade Examination Scope
Critical Examination
Close-up examination of representative exterior-wall areas and façade components.
Masonry Conditions
Review of brick, stone, terra cotta, mortar joints and other masonry materials for deterioration or distress.
Lintels & Support Steel
Evaluation of visible corrosion, displacement, cracking and deterioration associated with steel support elements.
Concrete & Other Exterior Materials
Review of cracking, spalling, delamination and other visible deterioration where applicable.
Unsafe or Deteriorated Conditions
Identification and documentation of conditions requiring repair, stabilization or further evaluation.
Engineering Report
Preparation of a condition report documenting findings, conclusions and recommended actions.
OUR APPROACH
From Field Examination to Clear Repair Priorities
Critical façade examination begins with understanding the building enclosure, the materials and structural components that support it, and the patterns of deterioration that may have developed over time.
Anax Engineering reviews available building information, performs close-up visual examination of representative façade areas and documents observed conditions using photographs, notes and location references.
Observed deterioration is evaluated in the context of material condition, extent, location and potential consequence. Where necessary, conditions can be identified for immediate stabilization, repair, additional investigation or ongoing monitoring.
The goal is to provide building owners with a clear engineering assessment of the façade condition and practical priorities for maintaining the exterior wall system.
01
Review Building Information
Review available drawings, previous reports, repair records and other building information to understand the façade construction and identify areas requiring particular attention.
02
Plan the Examination
Establish representative examination areas and coordinate access so that critical elevations, materials and façade conditions can be observed at close range.
03
Perform Close-Up Examination
Observe accessible façade materials and components, document deterioration and distress, and record representative conditions using photographs, notes and location references.
04
Evaluate the Findings
Assess the significance of observed cracking, corrosion, displacement, deterioration and other conditions and determine where repair, stabilization or further evaluation may be required.
05
Document & Prioritize
Prepare the engineering report, summarize observed conditions and establish practical priorities for required repairs, maintenance and follow-up action.
COMMON FAÇADE CONDITIONS
Understanding the Sources and Patterns of Façade Deterioration
Exterior wall deterioration often develops gradually and may result from long-term exposure to moisture, temperature changes, corrosion, material movement, aging sealants or previous repairs.
Anax Engineering evaluates observed conditions in relation to the façade construction and supporting structural components so that distress is not viewed in isolation. Patterns of cracking, displacement, staining, corrosion or material loss can provide important information about how the exterior wall system is performing.
The objective is to distinguish localized maintenance issues from conditions that may indicate broader deterioration, loss of support or increased risk to the building exterior.
Conditions Commonly Evaluated
Masonry Cracking & Displacement
Cracking, bulging, movement and localized displacement in brick, stone, terra cotta and other masonry elements.
Mortar & Joint Deterioration
Open joints, weathering, erosion and other conditions that may allow water intrusion or reduce masonry integrity.
Corrosion of Support Steel
Visible or suspected corrosion of lintels, shelf angles, anchors and other embedded or exposed steel components.
Spalling & Material Loss
Deterioration, delamination, cracking and loss of concrete, masonry or other exterior materials.
Sealants & Water Entry
Failed or deteriorated joints and conditions associated with moisture intrusion where visible during the examination.
REPAIR PRIORITIES & FOLLOW-UP
Turning Observed Conditions Into Practical Next Steps
The value of a façade examination is not limited to documenting deterioration. Building owners also need a clear understanding of which conditions require immediate attention, which should be repaired as part of planned maintenance and which can continue to be monitored.
Anax Engineering organizes observed conditions by severity, location and potential consequence so that repair priorities can be established in a practical way.
Where appropriate, recommendations may include temporary stabilization, localized repair, broader rehabilitation, additional investigation or future monitoring depending on the nature and extent of the observed conditions.
The goal is to give ownership a clear basis for planning repairs while addressing conditions that may affect public safety, façade performance or long-term durability.
Typical Follow-Up Actions
Immediate Stabilization
Temporary protection or stabilization where observed conditions require prompt action.
Localized Repairs
Targeted repair of isolated masonry, concrete, steel or other façade components.
Façade Rehabilitation
Broader repair programs where deterioration affects multiple areas or components of the exterior wall system.
Additional Investigation
Selective openings, probing, testing or further engineering review where concealed conditions require additional evaluation.
Monitoring & Maintenance
Ongoing observation and maintenance planning for conditions that do not require immediate repair but should continue to be tracked.
REPORTING & OWNER COORDINATION
Clear Documentation for Repair Planning and Ongoing Building Maintenance
A façade examination should provide more than a record of observed defects. The final documentation should clearly communicate the conditions identified during the examination, their significance and the actions recommended for the building.
Anax Engineering prepares reports that organize representative observations, photographs, condition descriptions and engineering conclusions in a format that supports repair planning, maintenance decisions and coordination with contractors and ownership.
Where repairs are required, the findings can also help define the areas that should receive further investigation, temporary protection or more detailed repair design before construction proceeds.
Our objective is to give building owners a clear and practical understanding of the exterior wall condition so that maintenance and repair decisions can be made with appropriate priorities and supporting engineering information.
