The City of Austin, Texas awarded J.F.White's Diving Group
the contract to remove dislodged Schlegel liner (plastic tunnel liner)
which threatened to completely block the Onion Creek wastewater
tunnel. City officials declared this liner removal to be an emergency
project and established an independent review committee to evaluate
proposals submitted by the three lowest bidders.
J.F.White did not offer the lowest bid price but developed the
most comprehensive safety program and most effective procedures
for this tunnel work. The liner removal was completed without
incident and achieved an early completion date.
This project included design, fabrication, and installation of a
forty-foot high bulkhead for the sewage bypass pumping system. A
unique Geographic Information System (GIS) was used with fiber
optic transmission to monitor underground personnel, equipment
and to insure safety.
J.F.White's design, safety and project performance provided
the client an effective solution for extreme Confined Space
penetrations.
