On February 5, 1973, Hubbard Construction Company, contractor for the
"J" Street storm drain and sewer project between East Park Lane and
Church Avenue, submitted a letter requesting an extension of time of
11 working days on his contract due to delays caused by inclement
weather. Under the contract, the work is to be completed by February
19, 1973.
In addition to the time requested by the contractor, this department
is requesting an extension of an additional 12 working days because
of trenching difficulties encountered as a result of sandy soil
conditions existing within the storm drain trench. This sand lens
~~ ~~
has resulted in numerous cave-ins which has limited the progress
of placing the 54 inch storm drain to an average of 44 lineal feet
per day. The excavation is 14 feet in depth with the sand lens varying
in thickness between 4 and 6 feet, 6 to 8 feet below the street surface.
The existence or extent of the sand lens could not be determined prior
to award of the contract unless the City took numerous test borings
during the design of the storm drain.
The contractor's request for the 11 day extension has been verified by the
Division of Engineering as being reasonable. The additional 12 days
extension requested by this department seems justified. The 23 day
extension, if granted will extend the completion date of the contract
to March 23, 1973.
