    As discussed in my first window article titled "The View Of Your Windows Is Not Always The Same", there is great variation in the suitability of a window for a particular application. In all cases, there is a very specific need for proper detailing and attention to detail with respect to integration of the window with the building envelope and proper detailing during installation. This sequel to my first window article focuses on quality control measures for installation once your window has been selected and specified.

    In March 2013 a catastrophic sinkhole collapse swallowed a central Florida bedroom killing the occupant without notice. The home was a total loss and the event made national news making many property managers keenly aware of the costs and dangers of sinkholes. Residents of the Northeast are not immune from these occurrences. Understanding possible causes and remedies should help with decision making at all levels of property management and ownership.

    Community associations, building owners, engineers, contractors and property managers deal with the constant battle of keeping water out of the building envelope, but sometimes the water that causes stains, mold and decay actually originates from within the building envelope. The cold temperatures of the winter months combined with specific interior conditions will result in excessive condensation. The condensation may be in the attic, basement and crawl spaces or inside wall cavities. Deficiencies in the original construction or recent reconstruction of exterior wall cavities, basements, crawl spaces and/or roofs /attics can exacerbate the conditions resulting in excessive condensation conditions and potential for damage and mold development. Sometimes, the conditions may be seen but many times the condition and subsequent damages may be hidden from view and worsen with each passing winter season, escalating repair costs.

    We have been responding to homeowner's complaints of sagging ceilings in the living space of townhomes which were built in the 1980's. Beginning in 2010 and continuing through today, Falcon Engineering has observed the condition of ceilings in over 30 homes in a Lincoln Park, NJ townhome community of close to 400 homes. Our findings are that upwards of 80% of the homes investigated have deflection which exceeds design criteria and are in need of repair. Repairs are relatively simple, but costly to the Homeowners Association having responsibility for the structural components of these buildings. Because of the need for financial planning, Associations want to understand the factors which influence the failures of these aging structures. For the purposes of this discussion, we are talking about failures which occur due to mysterious origin, rather than catastrophic failures of excessive wind or snow loads, or abuse from excessive loads that the trusses were not designed to accommodate (such as water beds or heavy stone finishing materials).

    It's that time of year again. That snow that is pretty for some is scary for others. You have experienced, read or heard about ice damming. You are familiar with the damage the phenomena can cause. Perhaps your Association has even spent several hundred thousand or even over a million dollars on roofing improvements and/or replacements within the last few years. Why do we have leaks from ice damming? Was the roof replacement performed correctly or designed correctly? The answer is simple, with a properly designed and installed roof system, the possibility of damage resulting from ice damming should be significantly reduced.

    Manufactured stone is a very popular product for both the interior and exterior of homes and buildings. There are many manufacturers of this type of cladding system, Cultured Stone® and Coronado Stone® among the most recognized names. A man-made stone manufactured primarily for decorative purposes, these systems are typically comprised of cement, natural aggregates and iron pigments. In order to give manufactured stone a realistic appearance and shape it is often created by using molds of actual real natural stones. Like many building materials, the use of manufactured stone has both advantages and disadvantages, and installation is vital to its long term success.

    You have a shiny new building with a shiny new crane and everything looks great. For some reason, though, the crane won't clear the building columns, even though the contractor and the crane manufacturer are saying everything is to spec and it's not their problem.

    It is absolutely critical in the evaluation of a legal case involving cranes, to determine what type crane is involved. The word "Crane" is a generic term that covers virtually anything that lifts with a hook, but each crane type is a whole different industry with different industry associations (which compile the industry product specifications), different governing specification and different OSHA requirements. As a matter of fact, some cranes don't even have hooks!

    The largest storage rack/ retrieval system, larger than two football fields and eighty feet wide was constructed to store 108 million pounds of paper products. On July, 2002, after two months of use, the facility collapsed and sparked a fire that destroyed the entire structure and 45 million pounds of paper. Nearly 50 fire departments responded to the inferno, which burned for three weeks. The owner of the facility sued a number of companies that included the contractor that designed and built the structure, a subcontractor, and the company that supplied the 110 foot steel columns.

    Many automobile accidents are complex cases with multiple events during a single accident. The aim of forensic investigations of such (and all other) accidents is to reconstruct the sequence and the severity of events during the accident and then to establish cause and- effect relationships between the injuries (or damages) and the probable factors - vehicle design (e.g. brakes, structure, airbags); vehicle operator (e.g. distracted driver, alcohol impairment, reduced vision); and operating conditions (e.g. fog, failed traffic sign, excessive speed, icy road).

    Hybrid cars have been on US roads for many years, starting with Honda InSight (1999) and Toyota Prius(2000) in mass production.

    In crashes between two automobiles, it is generally assumed that the lighter vehicle will suffer more damage and that its occupants will suffer higher levels of injury.

    This article contains a few of the findings from our recent study of automobile safety in frontal crashes. Parts of the data analyses are presented but details such as the relationship of a particular design feature to the measured injury indicators are highly dependent on specific cases and are available only for individual discussions.

    The New Car Assessment Program (NCAP) conducted by the National Highway Traffic Safety Administration (part of the U.S Department of Transportation) underwent major changes recently. For automobiles designated as model years 2011 and later, the changes involve both what is measured and what is published.

    Over the years, there have been several product liability litigations regarding pedestrians being injured and the front structure designs of the vehicles being alleged as the significant factor.

    The structural behavior of automobile seats and seatbacks is one of the factors often examined in investigating injuries to a vehicle's occupant(s) in crashes.

    Airbags in modern automobiles have been around for many years and their record in improving occupant safety in crashes is generally well accepted. However, many questions still arise regarding their deployment and performance in crashes.

    The "discrete damages/cost variance analysis method" for quantifying construction claim damages involves the specific distribution of all costs incurred on the project rather than quantifying only certain parts of the cost or damage analysis as may be used in the other methods.

    ABSTRACT - This paper provides guidelines to commercial construction cost engineers for the development of a plan for obtaining and utilizing subcontractor cost information for use in bidding, procurement, scheduling, change order management, and claim management. The paper is based upon personal field experience gained in cost engineering, scheduling, bidding, planning, contracting, and claim analyses.

    8/13/2013 · Construction
    A component of a construction claim often relates to the cost, quantity, and quality of the materials that the contractor installed on a project. The contractor frequently purchases these materials and agrees to install the quantities of materials on a unit price basis, i.e., a unit price that includes both the cost of the materials and the cost to install them.

    12/17/2012 · Construction
    Most construction contracts, whether they are standard or customized forms, usually contain specific provisions related expressly to the process of giving "notice." The notice generally refers to an obligation on the part of the Contractor to notify the relevant party administering the contract, normally the architect, resident engineer, or owner's representative, of a claim or change event that gives rise to possible additional entitlement for time and/or cost.

    4/13/2012 · Construction
    The equitable allocation of responsibility for project delays is essential to the resolution of many construction disputes. Contractors frequently assert that they have been delayed for reasons beyond their control. Owners often remain unconvinced that the Contractor is legitimately entitled to a time extension or delay, acceleration and loss of productivity damages.

  • Hydroplaning is frequently alleged to be a cause of vehicular traffic accidents. This is because many persons, even law enforcement personnel, may not know the technical definition and criteria for hydroplaning.

    Many vehicular accidents happen because drivers are in too much of a hurry or they are distracted by any number of things. They just are not paying close enough attention to their surroundings. Traffic accidents at signalized intersections are common where both drivers claim the other driver is at fault.
