    Most forensic investigation projects include a scope to determine the cause of some damage or condition. Project scopes often request determining the cause and origin of the damage. Since insurance policies contain descriptions of covered and non-covered situations, clearly specifying causes and origins is crucial for clients' coverage decisions. This article discusses the differences between and significance of these two important terms.

    Brick masonry chimneys have been prevalent for centuries, but it wasnt until recent decades that brick-clad, wood-framed chimneys became common in residential construction. This trend resulted from the increasing popularity of metal insert fireplaces. While they may appear similar from the exterior, the structure and weather-resistant envelope of wood-framed chimneys are very different than masonry-built chimneys. Prior to studying damage, it is important to understand critical elements in the structural support and weather-resistant envelope of wood-framed chimneys and the types of damage that can result from improper construction.[1]

    Fires can be caused by devices that fail due to a manufacturer's defect. Quality assurance procedures have gone a long way to eliminate out-of-box failures but manufacturers sometimes bypass quality checks on consumer products for competitive reasons. Even the most ethical companies are susceptible to human error that can cause an almost imperceptible change in an otherwise flawless manufacturing procedure.

    As the days get shorter and temperatures turn milder, most HVAC systems are taking a well-earned vacation. For a short while, a cool breeze through open windows will be enough to keep us comfortable in our homes. But soon, homeowners will switch their thermostats from cooling mode to heating mode, and some of them will unfortunately discover their HVAC system does not heat. It's time to pull out those extra blankets and make the call to a service professional sooner than expected.

    Wood bowstring trusses were used extensively in commercial buildings from the 1920s to the 1960s. Wood bowstring roof trusses provided long clear spans necessary in warehouse and industrial buildings. Many roofs supported by bowstring trusses are still in service today. Compared with other structural timber-truss types, bowstring trusses have exhibited more frequent structural problems. The structural deficiencies encountered are attributable to deficiencies in the original design of the trusses combined with damage due to exposure and age.

    The National Fire Protection Association (NFPA) has released a 2015 edition of NFPA 70E: Standard for Electrical Safety in the Workplace. It covers and assists in complying with the Occupational Safety and Health Association's requirements, including changes to requirements since the last edition. For personal safety in forensic studies it is important to stay informed of these updates. NFPA 70E covers arc flash risk assessment, establishment of arc flash boundaries, requirements of Personal Protective Equipment (PPE), use of PPE within the arc flash boundary, and equipment labeling requirements regarding arc flash hazards. The following examples illustrate the importance of staying abreast of the latest standards.

    History shows us that building codes have been around for a long time - in fact, the earliest known was around in 2000BC[1]. Penalties were also much harsher for construction defects. If a builder constructed a house that collapsed and killed the owner, the builder was not fined, but was put to death. The United States has been a country with diverse codes - as many as 5,000 at one time. More recently, however, various states and municipalities have adopted "model" codes such as the International Building Code or International Residential Code. These provide a "base" and may be used as written or an Authority Having Jurisdiction (AHJ) may amend certain parts of the model code, making it more stringent and/or specific for a certain area.

    There are many types, manufacturers, and sizes of commercial HVAC systems which can make it difficult to create general guidelines for repair procedures and estimates for hail-damaged units. This guide uses the most common "light commercial" rooftop units (RTUs), which are 5-tons, 7.5-tons, and 10-tons in capacity, for estimating time to repair or replace.

    Imagine for a moment that you are sitting in your home, listening to the rain while reading your favorite novel. Then suddenly you hear a roar of thunder and your home becomes dark. What just happened? You may have just experienced a power surge. Although lightning is not the most common cause of this phenomenon, it is excellent for illustrating what a power surge is and how it can affect your home. A power surge is a term used to describe a condition where the voltage and or current increases beyond its normal levels. Power surges, when due to the elevation of the voltage being supplied by the electrical utility company, have the potential to change data streams, interrupt electrical control circuits, burn out components, cause arcs, create shorts between conductors, overload systems, and cause system failures. The most common causes of power surges are indicated as follows:

    Concrete is a desirable construction material due to its inherent strength and durability, which make it well-suited for many applications in residential and commercial construction, especially foundations, floor slabs, driveways, sidewalks, and roads, among other things. In these applications, concrete that is properly designed, mixed, placed, and maintained will perform exceptionally well for many years. However, poor design or mix, improper placement, finishing techniques, or inadequate maintenance may result in concrete that does not perform as intended. Aside from cracking, which is probably the most common form of distress to concrete, since virtually all concrete will crack as it cures, surface distress due to scaling, spalling, and popouts are the most common forms of damage.

    The relationship between wind, hailstone velocity, and impact energy is based on an understanding of fundamental physics. Over a half century of laboratory research and field studies have determined that the severity of hail damage to a roofing material is contingent on the kinetic energy at the point of impact and the roofing material's resistance to that impact energy. These studies have found that a hailstone must be of a certain mass (i.e., size), and it must be traveling at a certain speed (velocity) to result in functional damage to the roofing material. The kinetic energy is a composition of mass and velocity, defined by the following equation:

    Chances are, it's happened to you. An unexpected period of cold weather occurs and temperatures drop well below freezing for an extended period of time. One morning you attempt to turn the water on in the kitchen sink and...nothing. Hot water? Nope. Cold water? Nope. What happened? Did you forget to pay the water bill...again? Chances are, your pipes are frozen. "How can that happen? They are inside the house!", you may say; however, just because your water lines are inside the building envelope, does not mean they are adequately protected from freezing.

    If hail impacts a roof covering and the effects of this impact result in some loss in the material's overall integrity or functionality, this material is classified as "hail damaged." More specifically for cedar shakes and shingles, valid hail damage is typically a new fracture of the cedar corresponding to a clean spot or scuff mark from the hailstone impact.

    Although sags along roof ridgelines can be discovered at any time, in northern climates they are often attributed to the effects of a past snow load. To make an educated analysis of the actual cause of this phenomenon, one must have a basic understanding of the structure and the loads to which it has been subjected.

    Heating, ventilating, and air conditioning (HVAC) systems consist of many components that work in unison to create the desired comfort level for our homes and offices. A well maintained system is designed to last around 15 years, but the life can be dramatically reduced when proper installation procedures and routine maintenance are not performed.

    Washing machine failures can create significant damage, exposing insurers and their clients to property damage. These failures often involve a high volume of water and can occur without warning. Through the examination of several hundred washing machines, the DONAN Component Testing Laboratory has identified a statistically significant failure trend in General Electric (GE) washing machines. The amount of water supplied to the tub of the washing machine is controlled by a water valve (solenoid-controlled valve) and pneumatic controls. The washing machine's load selector is a pneumatic pressure switch, which activates and deactivates the water valve.

    Shallow foundations are the most commonly designed and constructed structural foundation system. As opposed to deep foundations where structural loads are transferred to subsurface layers or multiple depth ranges, shallow foundations transfer loads to the earth (soil) relatively near to the ground surface. Some examples of shallow foundations include building components often seen in residential construction such as spread footings, continuous foundation walls and footings, slab-on-grade foundations, and mat-slab foundations.

    In urban and suburban areas, stormwater systems are found everywhere. From surface waterways, such as rivers, streams, and ditches, to subsurface drainage systems, such as storm sewers and culverts, stormwater systems are as ubiquitous as concrete, which is one of the reasons they are so important (Figure 1). Impervious surfaces like concrete, pavement, and roofs prevent stormwater from naturally absorbing into the ground, and the resulting runoff can cause flooding, erosion, and subsequent structural damage.

    For many years, the fire investigation industry has seen numerous fires involving livestock buildings. These fires are often high profile, especially when masses of animals are lost or injured. Many times these losses are in older structures with neglected electrical and/or heating systems.

    Large losses present a unique set of challenges from the perspective of managing an expert or team of experts. For the purposes of this column, let's assume that a large loss is one that exceeds $250,000. These might include heavy civil construction, infrastructure, transportation, or a catastrophic event affecting a large building.

    2/17/2015 · Construction
    Roof collapses can be sudden, catastrophic events caused by a particular loading condition or combination of loads. Roof collapses often happen with little or no warning, making this a particularly dangerous event. When investigating a roof collapse, the obvious perpetrators are examined: how much snow was on the roof, were the drains plugged up, were the winds in excess of the design wind speed and many others. Occasionally, the roof can be doomed to collapse months or years before an event due to design or construction related deficiencies allowing for a subrogation opportunity to recover cost of repairs.

    12/9/2014 · Construction
    Often after an event like a tornado, windstorm, water surge, or fire, the damage sustained to some property structures exceeds the value of it. In these cases, an engineer might be asked to determine if the remaining foundation system is suitable for reconstruction. The motivation for this is fairly straightforward: the property may have been underinsured and saving the foundation represents an effort to reduce the reconstruction cost, or there is a desire to get the structure rebuilt as quickly as possible. In the interest of time and money, an evaluation of the suitability of the foundation for reuse can be performed. There are three main questions for the engineer to answer: Is the slab damaged by the event? Are there any other factors, such as differential foundation movement, that would prevent the slab being reutilized? Are there any code considerations that prevent the slab from being reutilized?

    8/8/2014 · Construction
    In the wake of a Hurricane the monumental task of beginning to assess the losses and respond to the thousands of claims inevitably includes a number of claims concerning the functional assessment of commercial roofing systems. The design and construction of a roof system requires input from several disciplines including thermal considerations (Mechanical), fire resistance (Architect/Municipality), equipment carrying capacity (Structural), ability to drain and/or to store water (Architect/Civil), aesthetics, and the ability to resist any number of transient loads (Structural). The assessment of the damage sustained by a roof system during a storm event is an equally broad endeavor requiring the expert to call on a number of disciplines.

    3/20/2014 · Construction
    Building envelope assessments for storm-related damage is a normal part of job for the property adjuster and forensic consultant. The assessment of storm-related damage inevitably becomes a question of whether the observed condition pre-dates the storm or is the result of sudden and recent event. In fact, the question may very well be, "Did the observed condition exist during or even before the building was constructed; is the condition the result of a construction or design related defect?"

    Both large-scale catastrophe-induced losses and small-scale single event losses have the potential to impact employees, individuals, insurance personnel, general contracting restoration firms and associated property loss. In addition to the actual water-loss event, secondary losses can become equally as devastating depending on pre-existing and/or event-related building conditions, and the role the insured's take as part of required catastrophe restoration activities. During the water loss event, all project related information and environmental data generated is an integral part of the decision making process that may be disclosed at various stages to inform all the various "parties" involved with the project. All in all, a well-executed restoration project can minimize common delays and expenses of an ill-conceived and managed project.

    Sectors of the construction industry are reporting resurgence and growth in 2013. Single and multi-family housing, commercial, institutional and public works construction is predicted to increase up to 28% in some areas. This is good news for the industry and the economy but the increase in construction activity has historically led to an increase in construction accidents.

    In the course of an arson investigation one of the standard procedures is, when possible, to collect the clothing of arson suspects and have them tested for ignitable liquids. The hypothesis being that if the clothing tests positive for the same ignitable liquids that are found in the fire debris, it is good circumstantial evidence to place the suspect at the scene with an ignitable liquid.

    A growing concern in the insurance sector is soot and smoke damage claims due to wildfires. Some of these fires can affect properties hund reds of miles downwind, causing the potential number of claims to be astronomical. Besides the known risks for respiratory and other health problems, smoke, soot, and char can cause physical damage ranging from settled ash to property damage.

    3/24/2015 · OSHA
    Every year, approximately 3,600 workers are permanently disabled, and on average, one worker per day is killed, as a result of electrical incidents in the workplace.* To prevent these types of electrical injuries and deaths, building owners and managers should apply the safeguards included in NFPA 70E, the standard utilized by the Occupational Safety & Health Administration (OSHA) for building electrical assessments. OSHA utilizes the National Fire Protection Association's (NFPA) 70E Standard for Electrical Safety in the Workplace to provide improved safety procedures for workers through proper warning labels, restricted access notification, personnel training and personal protective equipment (PPE). OSHA compliance will minimize workplace injuries, accidents, illnesses, equipment damage, production losses, and legal costs, which are all avoidable and unnecessary factors in any business.

    Historically, fires and automobile accidents have been the primary types of property and casualty claims that presented a potential avenues of for subrogation. However, with the increased costs of mitigating the extent of water damage and reducing the potential for mold growth, claims involving large water losses have become another important area with subrogation potential.

    Mechanical ventilation systems have evolved from passive gravity vents (circa 1900) by adding modifications to improve comfort, occupant health, and energy efficiency. Early on, the maintenance of the system basically related to making sure the furnace was on and the windows would open. If you were lucky the school might have draft deflectors on the windows so the wind would not blow directly on your head.

    Following a hurricane, damages to a residential structure can range from structural distress, to small areas of mold growth to a total loss of the structure. Storm damage can affect multiple components of a structure including the roof, windows, siding, foundation and interior finishes. Wind or water is often the most common cause of damage to residential properties; however, there are many factors to consider when assessing the various causes of damage. Some of the factors include material use, age, condition and construction methods as well as type, location and extent of the damage. It is essential that a professional with hurricane damage assessment experience evaluate these factors to accurately define the cause.

    One sunny spring morning, on a rural road just outside of Houston, Texas, Molly Jackson, a vibrant 16-year-old girl with a bright future and a new driver's license, was behind the wheel of her father's brand new Chevrolet C2500 crew cab pickup truck. At the same time, just seven seconds before she would draw her last breath, Rhonda Simmons, a 46-year old divorced mother of two teenagers, was approaching from the opposite direction in her sleek and sporty Pontiac Trans Am.

    Editor's note: A trend to require more fire safety equipment in residences and nursing homes will reduce deaths and injuries, both among firefighters and the general public, says E.
