Revised estimated total for ABB with options for three buildings $1,482,021
*** ABB proposed two options that were not required in the bid specification. The first is an am detection and high
speed tripping system. The purpose of this system is to detect the presence of arcing faults inside the switchgear at a
very early stage before the fault magnitude is high enough to be sensed by the other types of bus protection. The cyst
is not a replacement for the standard types of bus protection. It is a complimentary enhancement to safety. The unit c
is $25,000 for including this in the Switchgear. The second item is to substitute ABB's low maintenance circuit bmak
in place of their standard breakers. The increase in unit cost per breaker would IM 100. The lifetime ownership cost
of these breakers will offset the higher initial cost. The low maintenance design has one moving part and is lighter
wei ht. DME proposes to accept both of these options.
