BACKGROUND: The original contract for the Parsons Avenue Miscellaneous Improvements - Rehabilitation of Collector Wells 101, 103, 104 & 115 provided for replacing existing laterals in the wells lined with deteriorating well screen, with new laterals, lined with stainless steel well screen. Due to unforeseeable adverse subsurface conditions the Contractor was unable to complete projection of 41% of the proposed new laterals in well 104 to the specified length.
