Prior to finalizing contract terms, it is strongly recommended that the Owner and General Contractor have a candid discussion to formulate a strategy for dealing with such circumstances when they arise. The process and procures should be in place prior to excavation. Allowances and contingencies can address the cost implications, but additional measures are required to deal with scheduling and factors impacting sequence of work. The Architect, Engineer(s), and Construction Surveyor should be made aware of the protocol for dealing with such unknown subsurface conditions prior to starting work.
