INFILL AND REDEVELOPMENT NOTE
A.Despite everyone's best efforts, it is impossible to fully display subsurface information prior to excavation. This is especially true in areas of infill and
redevelopment. Unknown subsurface conditions can have cost and schedule implications. 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.
Does not match the required format. See written comments.
