Twisted and distored main beam
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 12/23/2023
A twisted main beam in the basement could be the result of various factors, and it's essential to have a professional structural engineer assess the situation to determine the exact cause and recommend appropriate solutions. Potential reasons for a twisted main beam in a basement include:
Foundation Issues: Uneven settling or shifting of the foundation can lead to changes in the alignment of structural elements, including the main beam.
Poor Construction: If the basement was not constructed properly or if there were errors in the installation of structural components, it could result in twisting or misalignment over time.
Moisture Damage: Excessive moisture in the basement can lead to wood rot or deterioration of materials, compromising the structural integrity of the main beam.
Inadequate Support: If the main beam lacks proper support or if there are issues with supporting columns or piers, it could contribute to twisting or sagging.
Material Defects: Low-quality or defective materials used in the construction of the main beam could result in structural issues over time.
Given the potential safety concerns associated with structural problems, it's crucial to consult with a qualified structural engineer or a professional contractor to assess the situation, identify the root cause, and recommend appropriate remediation measures. Structural issues should be addressed promptly to ensure the safety and stability of the building.

Is the crack on my foundation wall serious ? When should I consult with a Structual Engineer.
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 12/1/2023
Assessing a crack in a foundation wall is important to determine its severity and whether it requires attention or repairs. Here are steps you can take to assess a crack in a foundation wall:
Examine the Size and Location:
Measure the length and width of the crack. Note its location on the foundation wall.
Generally, smaller, vertical cracks may be less concerning than larger, horizontal, or diagonal cracks.
Check for Movement:
Determine if the crack is active or stable. Measure the crack at different times and mark the ends with a pencil. If there is noticeable movement, it may indicate an ongoing issue.
Evaluate Crack Orientation:
Vertical cracks are often less problematic than horizontal or diagonal cracks, which may indicate structural issues.
Diagonal cracks that form a stair-step pattern could be a sign of settling or movement.
Inspect for Water Leakage:
Check for signs of water leakage through the crack. Water entry can lead to further deterioration and may contribute to mold growth.
If the crack is wet or has efflorescence (white, powdery residue), it suggests water infiltration.
Monitor for Additional Cracks:
Inspect the entire foundation for other cracks or signs of distress. Multiple cracks or widespread issues may indicate a more significant problem.
Examine Interior Walls and Floors:
Check for cracks or shifts in interior walls and floors, as these can be indicators of foundation movement.
Assess Severity of Movement:
Minor cracks without noticeable movement may be cosmetic, while significant movement or multiple cracks could signal structural issues.
Horizontal cracks are generally more concerning than vertical cracks and may indicate pressure from soil or water against the foundation.
Take Note of Surrounding Conditions:
Consider factors such as soil type, drainage patterns, and the presence of trees near the foundation. These can contribute to foundation issues.
Document and Photograph:
Document the crack with photographs and notes. This documentation can be useful for discussions with professionals and for future reference.
Consult with a Professional:
If you have concerns about the crack or if it meets specific criteria (e.g., significant size, horizontal orientation), it's advisable to consult with a structural engineer.
Review Home Inspection Reports:
If you have a recent home inspection report, review it for any mention of foundation issues. The inspector may have provided insights or recommendations.
Remember, foundation issues can vary, and professional expertise is often necessary to accurately assess and address the problem. Early detection and prompt action can help prevent more severe damage to your home.

Cracked sheetrock/walls! Should I be concerned?
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 7/7/2023
Noticing a cracked sheetrock can be concerning and determining the cause of the issue is critical. An experienced structural engineer can often diagnose the problem by assessing the nature of the crack and its relation to the house framing system.
Vertical and horizontal sheetrock cracks on the interior walls, can be due to the broken tape and usually not structurally concerning.
Diagonal cracks are the most concerning ones which require a careful assessment. Depending on the location of the cracks (interior wall, exterior wall, nature and orientation of the crack, etc) the cracks can be due to the main beam related issue (insufficient support, size, crack, termite, rot, etc), foundation issues (settlement, deterioration, etc) or other issues.
Here are a few examples when you need to engage a professional engineer for structural assessment
Progressive cracks on the exterior walls
Progressive cracks on the interior walls
New progressive diagonal crack at the corner of openings (door frames, windows, etc)

Can I remove a structural wall between my kitchen and dining room?
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 2/26/2023
I often get that question from home owners, landlords/investors, and potential buyers who are considering remodeling. Identifying the load bearing status of a wall requires an extensive knowledge about the structural framing system and comprehensive review of the existing structure. A Professional Engineer needs to perform a site visit and inspect the subject wall. He/She may need to access other floor areas and expose the ceiling/floor joists to determine the load bearing status of the wall. Professional Engineer can then design the safe and code-required beam and its support system.
In many cases, several additions have been added to the house over time with non-uniform structural system. Removal of a load bearing element without a proper substitute/alternative system can significantly impact the structural integrity of the house.

The money you spend on structural assessment of your house is probably your best savings!
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 3/6/2022
Regardless of the type of structure (residential, commercial, condominium, etc), your house/building is the most valuable asset that your safety and quality of life directly relies on. Structural repairs can be expensive, disruptive, and time consuming. Routine assessment of the building allows for early diagnosis of the structural issues which can significantly reduce the cost of repair. Most of the times, structural defective signs develop at the later stages of the process. Don't wait until you notice a concerning issue!
The frequency of the structural assessment depends on the age and condition, location (e.g., urban or coastal), type of the structure (e.g., wood, brick, etc), dwelling type (e.g., single-family, multifamily, condominiums, etc).
When should you reach out to a professional engineer for structural assessments?
Here are a few examples when you need to engage a professional engineer for structural assessment
Developing cracks (foundation walls, beams, joists, etc)
Rotting or boring insect damage
Progressive floor sagging
Framing separation
Unusual shifting

Healthy Foundation - Healthy structure!
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 5/8/2022
Different foundation types (fieldstone, reinforced concrete, cinder block) shows different signs under gravity and lateral loads. Foundation cracks (horizontal, diagonal, vertical, step-like, etc), foundation bulge or bow, and uneven settlement, should carefully assessed by a professional engineer to determine the cause and recommend proper course of action. The common reasons for foundation cracks are as follow:
Horizontal - outside hydrostatic pressure
Vertical (differential settlement) - insufficient footing specifications, lack of load bearing capacity of the soil, longterm water exposure
Diagonal - Non uniform soil profile, longterm water exposure
Depending on the foundation/crack condition, repair can be simple or complex.

Wait! My house is swaying during high wind - What should I do?
By: Dr. Farzam Maleki, PE - SurfZone Engineering Consultants - 5/19/2022
Roof framing system should be designed to support the structure for gravity (snow) , lateral (wind), and uplift loads (mainly). Additionally, it would secure the exterior walls from outward/inward movement. Roof structural members can be rafters, trusses, ceiling joists, ridge board/beam, or collar ties. Often, improper roof framing members (size, number, or location) can cause significant deflections.
If you feel your house sways during high wind - depending on your roof type,/span/specifications- you may need to have your roof framing system assessed by a Professional Engineer.
