is for the addition of blocking and framing at the roof structures.
Total: $30,254.57
Item #4: This is a structural change at the Concessions Buildings (3), serving window
openings. The construction documents show a CMU bond beam to span the
serving window openings. The contractor expressed concern about the length
of the span for a bond beam. Upon further review the structural engineer

will reimburse the City for this change. Total: $993.69
Item #7: This change added metal flashing to each of the 26 dugouts. Upon shop
drawing review the design team collectively determined that this was a better
long-term solution than what was exhibited in the plan. Total: $6,378.51
The construction contingency for this project is $590,000. The total of change order #1 and change
order #2 is $171,738.22, roughly 1% of the total construction project. With construction so far along
on the first pod of fields and concession stand the design team believes that we are well over 50% of
I1O
the exposure to future change orders. City Staff and design team believe that the changes that have
been made are a result of careful analysis to make sure the project is done correctly and avoid future
maintenance costs or lengthen the replacement timeframe. The quantities and pricing have been
discussed, analyzed and agreed upon by the contractor and the design team after several meetings.

Concessions Door Frame Depth
$993.69
This cost provided is for the reorder of door 1-101
on the concessions building to obtain doors of the
correct depth. This was due to a conflict on ETHOS’
door schedule. Since these were already on site and
purchased once, ETHOS will reimburse the City for this
change.
COR #012
Dugout Flashing
$6,378.51
Flashing within the dugout walls was not in the original
dugout design. In reviewing the shop drawings and
meeting with the Contractor and Mason on site; we
all agreed that this additional flashing would provide
a better long term solution for the owner. The cost per
dugout (26 of them) is relatively minor in comparison to
the long term benefit of the addition.
