Expert Witness and Construction Litigation Support

Jack Green Associates is provides expert witness services, construction litigation support and forensic engineering investigations to legal, insurance and real estate firms. By providing named witnesses in numerous mediation, arbitration, and litigation processes, we have developed an intrinsic sensibility and respect for the process itself. Our approach has earned us praise for objectiveness and capability to grasp core issues. This has made us particularly qualified in helping our clients identify their chances in a litigation process and servicing their needs as they engage in it. We have experience in minimizing developers’ exposure in building condominium projects. This comprises of plan review, regular follow-up in the field and close-out procedures. We focus on the items that are likely to become issues during the Turnover Process and later during the warranty period. Regular observations conducted in the field help identify and document potential issues. A comprehensive follow-up program endeavors to enforce attention to those very issues, and gives clear guidelines in mode and timing to resolve them. Finally, as the construction nears completion, the close-out procedure offer guidelines and specific services, such as review of as-built drawings, or warranty lists, for preparing the building for Turnover. JGA also offers services in assisting new Condominium Boards in identifying construction defects.
