While with them he designed water and sewage equipment and also the bascule moving machinery for the Lowestoft Bridge, in Suffolk.

In parallel with his design career, Geoffrey was first appointed as arbitrator in 1972 and his first foreign arbitration, an ICC appointment in Switzerland, took place later that year.

    12/4/2013 · Mediation
    International Commercial Arbitration, the chosen basis of the annual Willem Vis Moot, is arguably not au fond a process at law. It is quite simply the performance of an agreement between two parties to have a chosen third party hear and determine some difference between them.

    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.

    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.

    Electricity is a vital source of energy in our daily lives. It powers tools, provides light and heat. Our working lives are much improved and efficiency greatly increased thanks to electricity. But what about those situations where power from the grid is unavailable. Well, portable generators are an excellent tool for such a scenario.

    Safety culture is a term frequently bandied about in today's business world and sounds as trendy as "mission statements" were years ago. (Let's not forget "best in class". First time I heard this at a company meeting I looked around to make sure I hadn't mistakenly wandered into a dog show. Really?)

    Use fall protection; Use trench boxes when excavating; Lock out Tag Out any time repair or maintenance of equipment involving stored energy is performed; Slips, Trips and Falls are one of the most expensive types of injury. For my sixteen years in safety these safety hazards were always in the forefront of safety concerns for businesses and safety professionals. Guess what? Work related road way crashes is the number one serious/fatal injury cause for U.S. workers. OSHA recognizes this. CDC/NIOSH has generated a white paper studying this fact. Who knew? So here is some info on this number one safety hazard in the US work place.

    In the safety world hazard recognition plays a vital role in keeping your people safe from unsafe behaviors and/or conditions. Some hazards are easily recognized, for example an employee climbing up a 20 foot ladder with tools held in both hands. (This is a fall hazard by the way.) Common sense right? The safety guy who taught me safety had a great response to this attitude, "Few people have any sense (read knowledge) in common (read shared alike)". So while some safety hazards are immediately recognizable others require training to spot and avoid. Training is a key method in avoiding the "Ostrich Zone". One such hazard is Hydrogen Sulfide. You don't want to bury your head facing this hazard. (Won't do much good anyway, Hydrogen Sulfide is heavier then air!)

    "If you don't know where you are going, you will probably end up somewhere else.", so said Laurence J. Peter, a professor at the University of Southern California whose works touched the business world. (He is well known for the "Peter Principal".) Peter's above quote essentially points out that action lacking a clear objective will likely lead to unwanted or unintended consequences.

    When personal injury events occur legal negligence actions may arise. Common law negligence is established by plaintiff showing defendant owed plaintiff a legal duty, to conform to a standard of care, defendant breached that duty, plaintiff suffered injury and there is a causal relationship between the breach and injury. FN 1 But what sources of standard of care proofs are available? How does a litigant go about proving standard of care?
