Lawsuit has been filed against a general contractor for negligence, breach of contract, fraud, etc. Defense expert (hired by general contractor’s attorney) has been given access to photograph, & walk around homeowner’s entire residence; and all area where claims have been made in the lawsuit were pointed out to the expert. Part of the construction must be torn down and rebuilt. Homeowner has hired a new contractor is now ready to tear down and rebuild. Defense expert wants to be present during the entire demo process, which seems completely unnecessary. Plaintiff wants to allow their expert to come by at a time when the construction workers are not there. What is the Industry norm for how much access opposing side’s expert is given?
