1. Assistance in obtaining a building permit from Ada County for the addition to the existing
pump house. I am requesting a design fee increase of $900 for this i[cmt. Any fees charged
by Ada County will be paid by the City of Meridian.
2. Redesign oP the pumping equipment to include valuing and piping to automatically by-pass
flow from the well on start-up Cor water quality purposes. There is currently no location to
discharge the by-pass flows. The plans will terminate the piping at the north wall of the
building addition for future connection to either a gravity pipeline or pressure pipeline. 1 am

existing booster pump building afrer the original plans were developed. We will show the
reiocated position of the fire sprinkler controls, backfiow prevention equipment, and building
connections on the plans. We will include a bid item for relocation of this equipment, and
design of modifications required for the well room addition to the building by a licensed fire
sprinkler contractor. 1 am requesting a design fee increase of $1,300 for this item.

requesting a design fee increase of $4,200 for this item.

2. W'e need to nut the new plans through the Ada County building department to get a building
permit for the addition. Add any time necessary to acatmplish this task.
3. Afire sprinkler system has been installed in the building. We need to relocate ilte service and
control panels from the west wall of the existing pump mom to the west wall of the new pttmp
room and add sprinklers to the new pump room. My thought is w require [he contractor to hire
a fire sprinkler tympany to do all of this work. [s tttc fire sprinkler relocation something your
mcx hanical staff can design?
The following is a list of plan changes 1 have made that affect your design:
I . :Moved the ViT) to south wall.

3. Moved water level monitor to the west side of the pump.

7. Added a sokmoid controlled valve at northwest comer ofthe pump room.
8. "I'he conduits on the outside of the existing building at the southwest comer now have
