Geoffrey Beresford Hartwell is a Chartered Engineer who practices as an Arbitrator, Adjudicator and Expert for Determination. Geoffrey is the former Senior Partner of Consulting Mechanical and Electrical Engineers BHA Cromwell House.

A one time Chairman of the Expert Witness Society, Geoffrey Hartwell has experience giving evidence in court (in both civil and criminal matters) and in International Arbitration. He sometimes is retained as a Single Joint Expert or as a Tribunal Expert. His services are offered to both Plaintiff and Defense. Even when retained on behalf of a Client he, like all Experts, has an overriding responsibility to the Court or Tribunal.

After his early career in aerospace and nuclear energy, Geoffrey entered private practice in association with the late Leslie Heap and Gerald Lewis of Heap and Digby, Consulting Engineers, in 1969. While with them he designed water and sewage equipment and also the bascule moving machinery for the Lowestoft Bridge, in Suffolk. He practiced also as Beresford Hartwell and Associates and, in 1971 established a separate office in Wallington, South London.

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. He studied Law to Intermediate level and then transferred to the examinations of the Institute of Arbitrators (now Chartered) of which he became Chairman in 1996-1997 and for whom he taught in various countries on several courses, including the prestigious Diploma in International Commercial Arbitration.

    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.

    In many places of NYS, public water supply systems are available. If your site is situated in such a location, then the lots which will result from your contemplated subdivision will be required to draw their water supply from the municipal water system

    3/5/2009 · Construction
    As you enter into a contract to buy a piece of commercial or industrial property, you should always keep in mind that your new town and county have rules which you must abide by. With regard to the exterior areas of your premises, there are rules concerning your septic system, the maintenance of your building, the addition onto your structure, etc

    12/28/2006 · Construction
    In developing a vacant piece of land, steep slopes are often an issue. And, the more prevalent the steep slopes are on a site, the greater the likelihood that retaining walls will be part of the Approved Site Plan. Let us consider three municipalities which regulate the final allowable slopes for land which is filled, cut, or graded

  • 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.

    Gordon Culp, et al
    Does your project team see you as a leader or a manager? Project teams must be led rather than just managed in order to unleash their full potential, energy and enthusiasm. This book examines what it takes to make the crucial transition from project manager to project leader. All too often project managers rely on their technical skills and computer-generated information about project status in their attempts to achieve success, thus confusing management with leadership. Rarely does a project fail due to lack of technical skills. Instead, relationship and communication difficulties play a key role in poor project results.
    Gordon Culp, et al
    Ever wonder why some project managers are consistently more successful than others? The best trained managers are not always the most effective--and this book explains why.
