Re:
Change Order #9 for Asia, Project #MZ-0044
Location:
Oklahoma City Zoological Park
Purpose:
This change order covers the changes made from:
P.R. #55 Provides below grade roof drain collection to storm
sewer as requested by zoo staff following the bid. This should
prevent erosion below the elephant barn and allow the vegetation
to grow in quicker
P.R .#56 Rev. #2. Installs a fire truck turnaround near the haybarn
as requested by the fire marshall to obtain the occupancy permit.
The fire truck turnaround around was not included in the bid set
because during two meetings with the City prior to bidding, the fire
marshall reviewed the plans and found no objections at the time.
P.R. #56 is value engineered from a grass pave drive, to the
concrete drive as shown.
P.R. #58 Changes the elephant hot wire detail from a copper
stanchion to fiberglass stanchions, and provides a third energizer
requested by the staff following bidding to run each paddock
independently. These changes are recommended by Gallagher
the hot wire MFG, and results in a credit back to the zoo.
P.R. #60 Reroutes fire protection piping out of the elephant
community stall, where they would have been within reach.
P.R. #62 Rev. Provides Elephant House roof flashing, gutters,
downspouts and associated wood theme work furouts as
requested by zoo staff following the bid. This should prevent
erosion below and allow the vegetation to grow in more quickly.
P.R. #67 Provides natural cut stone rock retaining walls at the
switchback to prevent erosion and increase the ease of planting
as requested by horticultural staff following the bid set. This
proposal request is value engineered from rockwork retaining
walls.
P.R. #68 Roughs in PVC and EMT conduit for a future
communications system. Was originally going to be owner
provided, but considering work in the area was taking place, it
makes sense to do it now.
P.R. #70 Provides electrical service from the Thai Demonstration
Pavilion to the electric gate operators on the northwest side of the
museum.
P.R. #71 Provides access doors in the utility rocks for the hose
bibbs located in the elephant exhibit areas. The hose bibbs are
inset into the rockwork, the access doors are for the vacuum
breakers which are required by code.
P.R. #72 runs gas piping to the emergency generator and split
system furnace unit at the mezzanine office, which was left out of
the bid set.
