Happy New Year 2024!

Professional Engineers can determine the cause of a parking lot slip, trip, and fall accident. A Professional Engineer can also determine which codes and standards are violated, whether the hazard was created by the owner, whether a pedestrian injury is foreseeable, etc..

Many accidents and resulting injuries occur because of parking lot defects. Among the services provided are investigations and reports on slip, trip, and fall and other accidents caused by parking lot defects. Harold Krongelb PE has investigated many parking lot slip, trip, and fall incidents at a wide variety of sites including restaurants, parks, museums, office buildings, homes, apartment buildings, outside steps, sidewalks, playgrounds, and more. These locations are prone to defects such irregular stairs, improper handrails, unsafe curbs, poor or improper maintenance, improper design, improper construction, unsafe equipment, and improper repairs.

Misleading Coefficient of Friction

Building codes are designed to protect the public. In addition, there are numerous standards published covering virtually all aspects of modern life. These standards also serve to protect the public.

In many cases, City of New York Codes or State of New York Building Codes are applicable. By including code references in the reports, it becomes obvious how the code violation contributed to the injury, and how following the applicable codes would have helped prevent the injury.

When performing parking lot slip, trip, and fall investigations, Harold Krongelb PE analyzes the site and determines the cause of the slip, trip, and fall accident. If appropriate, photographic images and measurements are taken to document the conditions at the site. It is then determined which codes and standards are applicable, and how conditions at the site violated the codes and standards.

After the research, a report is prepared describing the conditions at the site, the cause of the slip, trip, and fall and the code and reference standard violated. The reports are clearly written and help all parties understand how the hazard caused the accident and subsequent injury.

Building Code Resource Information

Proximate or Substantial Cause

Proximate cause is often defined as the immediate or closest cause. Substantial cause can be defined as being a significant factor or contributing significantly to an incident. When examining a site or building where a personal injury occurred, it is important to determine the proximate or substantial cause of the incident. Some Engineers cite irrelevant deficiencies as the cause of an incident. For example, if a client falls at the top of a set of steps, hazards near the bottom of the steps are irrelevant.

There are many experts who look to find any defect or hazard and never determine if it is the proximate or substantial cause of the accident. It is important that only relevant defects, hazards, and codes are included in reports. Engineering reports that include irrelevant information may look good at first, but these reports can be defeated in summary judgment.

The Laws of Physics
Do Not Change

A Professional Engineer's report or affidavit needs to reflect the Engineer's professional opinion based on well-accepted scientific, engineering, and mathematical principles. Common sense is also an important component in an Engineer's analysis. If your case is based on "facts" that do not obey to the laws of physics, revisit the case. The laws of physics do not change because of your client's testimony. This is a critical point when writing a report or an affidavit.

Conditions Changed?
No Problem

About 40% of the personal injury consultations are regarding hazards and defects that no longer exist. Another 45% of the personal injury consultations are regarding conditions that are either transient or have had some changes even though the hazard or defect has not been corrected. In only 15% of the personal injury consultations are the conditions unchanged.

For some personal injury consultations, access to the premises is denied without multiple court orders, is provided with restricted access to hinder the site examination, or the defendant delays the site access to the point where a report needs to be issued without a site examination.

Many personal injury consultations must rely (at least in part) on photographic images. As long as the photographic images fairly and accurately represent the site as it existed at the time of the incident, a Professional Engineer's report detailing hazards and code violations can be created.

Professional Fees

You will be quoted a fixed fee based on the information provided. There is no extra fee for answering your questions on the phone. If you request an increase in the scope of the consultation, additional fees are always discussed before any Engineering work is performed. You know the expected fee for the professional services when work is started.

Professional Engineers are prohibited from working on a contingency basis. Professional Engineers are prohibited from engaging in fee-splitting, which means no referral fees are ever paid.

Trivial Defects

De minimis means too trivial or unimportant to be considered. A de minimis defect is a defect that a defendant is arguing is too small to be considered as the cause of the accident and injury.

Who decides if a defect is de minimis?  Is it decided by Attorneys, the law, or the Engineer?  Engineers need toconsidert whether a defect is trivial in determining the proximate cause or substantial cause of the incident and subsequent injury. It a Professional Engineer determines that a defect is the proximate cause of an incident, then the defect is not trivial.

Foreseeable Incidents and
Reasonable Care

The cause of injury is often the defendant's failure to use reasonable care in the maintenance or repair of a building. Engineers need to look at the site conditions, and determine if the owners created a defect or hazard by failing to use reasonable care. It is also important to determine if it is foreseeable that the condition could cause an injury.

Engineers and Medicine

Professional Engineers are not Physicians and cannot provide a medical diagnosis or medical advice. However, it is important for Professional Engineers performing personal injury consultations to have a basic understanding of the mechanism of injury, how a human responds in different situations, how different medical conditions are treated, etc. Often it is necessary to read documents written by first responders, nurses, and doctors to understand the connection between an injury and a hazardous condition.

Professional Engineers are not Medical Doctors, and are not providing medical opinions on the treatment of an injury.; However, a Professional Engineer should obtain all relevant information, including medical information, to provide a professional opinion as to the cause of a personal injury.

Engineer Experts or Hired Guns?

Some Professional Engineers are "hired guns". These expert witnesses provide a report in favor of their client regardless of the facts, the laws of physics, or reality. It hurts to exaggerate or embellish findings. If there is no defect, that is what the Professional Engineer must tell you. There are Attorneys who will never use my services because I do not embellish the reports in favor of their clients.

Embellishing a report or relying on code references that are not applicable may work if an insurance company settles based on an inaccurate report. In other cases, the expert's statements in the inaccurate report cannot stand up to summary judgment or under cross-examination in a Court of Law. Harold Krongelb, P.E. provides a professional opinion based on the reality that should hold up to summary judgment or under cross-examination.

Words are Important

It is important to know what to say, what not to say, and how to phrase findings. Judges typically do not accept medical, psychological, legal, financial, etc. professional opinions from Engineers. Yet some Engineers routinely provide these opinions in their reports. These non-Engineering opinions often do not hold up under summary judgment.

It is important not to make statements that might be misinterpreted as being beyond the scope of a Professional Engineer's expertise. Even an otherwise well-written report can be thrown out in summary judgment if an otherwise accurate statement is misinterpreted.

Everything in the reports is designed to stand up to summary judgment and under cross-examination during trial. This has been tested during many court trials and summary judgment decisions.

"Old School" Engineers

After World War II, Engineering moved from war-related work to developing products for consumers and of national interest (such as the space program). There were few universally accepted standards other than building codes and mechanical standards such as standard screw and wire sizes. Many Engineers who graduated before the mid-1970s created their own standards, often changing these standards from project to project.

Although organizations such as the American National Standards Institute (ANSI) began developing standards after World War I, many of these standards did not acquire the force of law or become well accepted practices until the 1960s. In addition, organizations such as the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) set and enforced standards. Organizations such as ANSI and the Consumer Product Safety Commission (CPSC) set standards that may not have the force of law, but are universally followed.

Some "Old School" Engineers retired from full-time employment to become consulting Engineers. These "Old School" Engineers approached accident investigations like they had worked their whole life. The result was reports that reflected the "Old School" Engineer's standards or the Engineer's interpretation of Building Codes without regard to the realities of how the Department of Buildings interprets codes or good and accepted practices.

An example of the difference between old self-created standards and newer standards can be seen in the change in automobile safety in the last 50 years. In the late 1950s, automobile manufacturers advertised how safe their cars were. The standards for safety were set by automobile manufacturers. In the late 1950s, General Motors stated their cars had a "safety X-frame" in advertising.

The Insurance Institute for Highway Safety released a video in 2009 that showed a frontal offset collision between a 1959 Chevrolet Impala and a 2009 Chevrolet Malibu. Analysis after the collision showed that the driver of the 1959 Impala would have died instantly, and the driver of the 2009 Chevrolet Malibu might have sustained a knee injury. Video of a 1959 and a 2009 Chevrolet Impala Collision

This video illustrates the difference between self-created standards based on a few theories and well-developed, well-tested, and well-accepted standards. By the self-created standards of 1959, the Impala was "safe". By today's standards, the 1959 Impala offers little passenger protection.

When choosing a Professional Engineer, be careful of Engineers who define their own standards. While they may sound good, their testimony will hold up no better under cross-examination based on today's standards than the 1959 Chevrolet Impala held up against the 2009 Chevrolet Malibu.

Accident or Incident

Accident has no clear meaning. An accident could be an injury caused by a property owner's negligence. An accident could be a mistake by the injured party. An accident could be caused by a contractor's negligence.

A Professional Engineer evaluates incidents. Someone is injured, which is the incident. It is only after the incident is evaluated that the cause of the incident and negligence can be established.

When an incident is evaluated, there should be no preconceived notion of who is responsiblle, why they are responsible, or how the defect or hazard was created. An incident should be evaluated in a methodical and unbiased way, including the application of well-accepted scientific, engineering, and mathematical principles. Only after all the facts related to the incident are determined can negligence and blame be determined. It is noteworthy that this approach often finds a much more significant defect and yields a much better case for your client.

Sidewalks, Stairways, Paths,
and Means of Egress

A trip and fall on a public sidewalk is different than a trip and fall on a stairway, ramp, or other required means of egress. The standards and applicable codes are often different. Sidewalks by their nature have irregularities and pedestrians need to exercise reasonable care. A concrete path that is part of a required means of egress may be held to a higher standard than a sidewalk along a street. A Professional Engineer needs to determine which codes and standards are applicable.

Building Codes and
Engineering Standards

It is important to determine which codes, regulations, and standards are applicable to a specific incident. When a building is constructed, it is constructed under the codes, regulations, and standards that are in force at the time of construction. Harold Krongelb PE has an extensive searchable library of historical codes is available and includes:

• 1877, 1892, 1899, 1901, 1906, 1916, 1938, 1968, 2008, 2014, and 2022 City of New York Building Code (including amendments).

• 1951, 1954, 1959, 1964, 1972, 1978, 1984, 2004, 2010, 2015, and 2020 State of New York Building Code (including amendments and construction manuals)

• 1938 FHA Construction Standards
• 1907, 1909, 1915, 1922, and 1934 Fire Underwriters Model Code
• State of New York Multiple Dwelling Law
• State of New York Tenement Law
• City of New York sidewalk regulations
• Electrical Codes

In addition, there are numerous standards that have been published by many different organizations. These standards can help, but a Professional Engineer must be cautious when applying them. For example, a national standard for the measurement of slip resistance of a surface was withdrawn when it became apparent that the standard was nothing more than a sales promotion for one manufacturer's testing device.

Most important is knowing which codes and standards apply to which locations. If irrelevant codes are cited, the Professional Engineer's report is of little use.

Codes, regulations, and standards change over time and modifications are made to existing buildings and sites. It is important to examine the available history of the building to determine what codes, regulations, and standards are applicable.

The term grandfathered is often applied to existing construction. Saying a building is grandfathered is often inaccurate. Grandfathered only applies to original unaltered construction. Grandfathering requires that no changes were made without required permits and approvals. Once a change is made to a building, newer building codes, standards, and municipal regulations become applicable. For example, making a change to the interior of a building might require that exterior steps be brought up to modern codes. Just because a building complied with the applicable codes at the time it was constructed does not mean that hazardous defects are permitted.

Even if the building or site is unaltered, it may not have complied with the codes, standards, and regulations in effect at the time the building was constructed. Many older codes, regulations, and standards are not as clearly written as their more modern counterparts.

The Engineer needs to consider both the wording and the correct application of the code, regulation, and standard. In addition, the injury may have been caused by faulty maintenance, which may be a violation of current codes.

Just because a building complied with the applicable codes at the time it was constructed does not mean hazardous defects are permitted. Failing to maintain a building or site in a safe condition is never grandfathered.
