    3/12/2018 · Construction
    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.

    8/2/2017 · Construction
    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.

    9/27/2013 · Construction
    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.

    On December 3, 1984, at a pesticide ingredient manufacturing facility owned by Union Carbide, a leak occurred in the Methyl Isocyanate (MIC) plant. Due to the toxic nature of the gases released and the plant's proximity to local residences, the death toll was in the thousands; both plant workers and nearby residents. The first recorded public meeting in response to this incident was on December 9th, in Institute, WV, the site of Union Carbide's only US MIC production unit. Full disclosure: my father was a research & development chemist for Union Carbide and Institute is about 10 miles down the Kanawha River from my hometown of Charleston, WV.

    Welcome to the second part in our multipart blog series examining a young boy's fall and injury at a public playground. If you missed the first part in this series, click www.warrenforensics.com/2017/10/11/children-will-fall-at-playgrounds-what-shall-we-do-to-protect-them-a-multipart-blog-series-part-i/ to read it. In this post, we will highlight some resources that designers of public playgrounds can use to help ensure their designs are reasonably safe.

    Many people just take for granted that something is just going to work, and in many cases assume that it will work forever. One such device that does not get enough attention is the Ground Fault Circuit Interrupter (GFCI). Simply put, a GFCI is a protective device that compares the current flowing on the hot and neutral wires of the circuit and will "trip" to disconnect power to the circuit if a small imbalance of current is detected. The imbalance of current is an indication of a dangerous alternate path for the current to flow from a damaged line cord or a fault inside an appliance and constitutes a shock hazard to a person.

    In 2011, a 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman's pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy.

    Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.

    When thinking about the safe operation of boilers (and don't we all?), several systems can readily be named; flame control, fuel/air ratio; steam pressure control, levels in the vessel, etc. What about the water? It seems so passive, as long as there is enough for level control, what's the big deal? Well, it turns out, that as the steam produced by a boiler is used in the process, the condensate from that steam is returned to the boiler as feedwater. However, since 100% of the condensate is not returned, whatever solids had been in that water before it evaporated to form steam are left in the remaining water. Fresh feedwater is added to maintain levels, but even fresh water contains some dissolved solids. So over time, the water in the boiler system gets saturated with all sorts of dissolved minerals.
