Transmitted herewith please find a copy of Archer Westerri s contract modification request
(CMR) to adjust clarifier 2, 3, 4, 5, and 7 weirs to accommodate the brush assembly and scum
beach conflicts. The pricing includes additional labor and material cost for making the weir
adjustrnents. The cost associated with this work is $40,747.42. No change to Contract Time

CDM Smith has reviewed this price proposal and is of the opinion that it is a fair and
equitable price. CDM Smith recommends the City accept this cost and issue a Change Order
in the amount of $40,747.42. Please advise if the Water Department desires this CMR be
incorporated in a Change Order.
Very truly yours,
