Just heardon radio on RTE that their is a directive between the govt. of Ireland and the National Road Authority under the town council that construction or developement of road should be employed an archeologist to scan the landusing method like geographical survey or other method for the preservation of site if they found one or new find. Is this kind of thing also practice in GB? Is private and public contractor also have a guide on what they will going to do when they found a site,well some project amount alot of money a delay by archeological excavation is a lost to them and the other thing is if the site is important they have to find a new one. Project contractor as I saw on TV on one of your documentary in BBC that local contractor have a knowleged of find on the area and sometimes ask by other expert for info on what find they encounter on several sites to compare and study thier recent finds is this the case that other that are working in this kind of job was no guide especially on contruction industries on what they are going to do when they find a site or they just keep thier eye blind if that is the case at least they should record or plot thier find and go on with the project. Their are cases that expert are given time to excavate a site for future consruction of a building that is a good thing but sometimes they all dont finnish their dig on time,on emplyoying a archeologist expert on a goverment or developer is a big help but for me it is much better that other in this line of work are being given a crash courses from that start and expand later for thier are some documentary that expert on the 50s or 60s employ consruction worker not all student or expert when they are digging a site for me it is much better if most on the construction thing have a course, just a man power of them it may help some thing even on small info they will input. Saw some construction worker here have a metal detector maybe looking for a pipe or electrical cable because they are using a backhoe maybe for safety or because it is a directive. Any additional info.
