We have a project which is located in a historic district and it is required by the local authority that before the start of construction, archaeological works have to be undertaken together with removal of a few trees. Archaeologists will have to do some small excavations to verify if there isn't anything of archealogical value that should be preserved. This has to be done by an independent company not related to the general contractor before the start of any construction works. Moreover, these archeological works have to be organized by a company from which the Investor bought the site - it means that this is not a responsibility of the Investor. Does anybody know if this phase - archealogical research and removal of some trees should be included in this prerequisite and the Erosion and Sedimentation Control Plan?
