SUBJECT:
Amendment to the Agreement for Design of a Digester Mixing System at
the Encina Water Pollution Control Facility.
Statement of the Matter
At their December 6, 1978 meeting, the Carlsbad City Council approved an agreement with C M
Engineering for design of a mixing system for Digester No. 2 at a cost not to exceed $4,600.
The project was advertised for bids twice resulting in no bids at the first opening and un-
acceptably high bids at the second opening. Finally, the project was accomplished through
the Carlsbad open market procedure. The various components of the project were separated
and subcontracted. The mixing system was redesigned by the Engineers to accommodate a new
support system and different pumps than those specified. During the procurement, fabrica-
tion and installation of the components of the system, the Engineers assisted in developing
installation methods, requesting quotations on pipe, fasteners, and equipment and in the
actual intallation of the tube.
Accordingly, the total expenses incurred under the original design contract were $5,973.33,
or $1,373.33 in excess of the original fee.
At the October 25, 1978 JAC meeting, the Advisory Committee unanimously approved a recommen-
dation that the Agreement be amended to reflect the increased scope of work. Adequate funds
are available in the Encina budget.
