    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.

    Contractor’s claim submittals and expert reports are often deficient in proving causation, i.e., the cause-effect linkage. These claims generally outline the owner-caused impacts and separately calculate quantum; however, the two are often not linked in any meaningful way. Most claims are settled prior to a decision by a panel, court, or board, and therefore these deficiencies are not made apparent. Yet, a well-prepared claim document which includes a persuasive and accurate causeeffect analysis can greatly improve the contractor’s chances of a successful recovery, either through negotiations or in arbitration/litigation. This analysis is difficult and often costly to prepare, and is therefore not performed in many disputes, which may be the reason why the claims fail.

    The leader of a corporation or project is the individual who must ultimately be willing to take responsibility for results. Within the context of an organization or team made up of individuals, it is the collective performance of the individuals, as a team, that defines the results of the whole. While it can be said that the best motivation is internal motivation as opposed to external motivation, the leader is ultimately the one responsible for creating the conditions where motivation can thrive.

    11/13/2017 · Construction
    Time is money especially on engineering and construction projects. Because delays in the completion of the project usually result in increased owner, engineer, and contractor costs, the overall time of performance is vital to the financial success of the project. The importance of time is evidenced by the significant role played by CPM schedules, completion dates, and milestones in the bidding and awarding of engineering and construction contracts. The desire to minimize costs and the time of performance often causes the occurrence of acceleration.

    10/4/2017 · Construction
    In the construction industry, it is largely agreed that overtime work adversely affects labor productivity. However, there is no universally accepted method for estimating the resulting loss of productivity, and many of the studies commonly used to estimate such losses have been subject to criticism by industry experts and the courts.

    The Collapsed As-Built Windows Schedule Analysis (AACE® International Recommended Practice 29R-03, Method Implementation Protocol 3.9) is a modeled, subtractive, multiple-base method. It is a retrospective CPM schedule analysis which is typically used to prove entitlement for compensable delay and assess concurrency of delay within a window of time. The analysis simulates the as-built conditions within a schedule window and then delays are removed from the CPM model. If the forecasted project finish date “collapses” but-for or absent compensable delays, then entitlement for compensable time-related costs can be demonstrated. This article addresses the usage of the Collapsed As-Built Windows protocol and the advantages and disadvantages of the methodology.

    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.
