Change Order #2 Summary
Date: 05/09/2025
Change Order#2 to the contract with Muniz Construction includes changes to the current phase of
construction.These changes include:
Revise North and South Bridge Abutments: This item is associated with resurveying work associated
with moving the bridge abutment slightly.
Cost: $1,820.00
Remove Revegetation from contract: The City made the decision to revegetate the site post-
construction outside of the contract. This price was exponentially higher than if the City was to contract
directly with a vendor. Removing this scope resulted in an overall credit to the project.
Cost: $-103,216.50
Landscape Revisions—Centennial Plaza: Due to changes in the abutment in Centennial Plaza, slight
changes to the landscaping was necessary and resulted in a credit to the project.
Cost: $-833.00
Differing Site Conditions: While drilling the pier for the bridge abutment,the contractor encountered
site conditions that were outside of what was shown in the geotechnical report. The geotechnical
report showed native ground with an appropriate bearing capacity. Upon drilling,the contractor found
junk fill that sluffed off the bank and was not appropriate for bearing the bridge pier unassisted. This
required the contractor to stabilize the bank to continue.
Cost: $14,240.00
Drainage Issues between Stations 25+80 and 30+00: This area of the project was identified as a
potential erosion issue during flood events. This section of trail is within the floodway, but bearing on
rock. After consulting with the engineer and contractor, it was decided to dowel into the rock to anchor
the trail section.
Cost: $15,170.00
Demobilization/Remobilization: Due to the conflict with the wastewater line,the contractor was
required to demobilize. In order to do this, they had to remove all equipment, in addition to make the
site safe. This item also includes the manhours and equipment deliveries to remobilize and start the
work after the utility conflict was resolved.
Cost: $36,419.00
Topographic surveys pre-and post-utility work construction: The contractor performed a survey after
before the utility contractor began work on the encasement of the wastewater line. They then
performed a survey after the work was complete to ensure that the site was left in the same condition
as when they left.
Cost: $3,781.00
Delivery of bridge and additional labor: Because of the timing delay,the contractor delivered the
pedestrian bridge to the site. This required an extra crane rental to remove form the delivery truck.
The number the contractor included in their bid for crane rental was a one-time event(taking it from the
delivery truck and installation same day). Therefore,this was an added expense they did not plan for.
Additionally, PARD requested that the bridge be staged in a specific area of the parking lot to not
interfere with large events in Centennial Plaza, like Diwali, Dia de los Muertos, and Pride. This requires
the contractor to set the crane up to relocate the bridge to the back of a truck,then move to the area of
the installation and set the crane up again. This was an added cost to the project.
Cost: $13,706.00
Modifications of Quarry Block Wall after Utility Work: After the utility work was completed,the wall
details needed to be modified. Additionally,the trail was relocated in an effort to limit the amount of
impact on the waterline as much as possible,thus limiting the amount of steel encasement required by
their contractor. As such, quantities change,depths of footers changed, wall heights changed, etc. This
item includes credits for the bid items that would have encompassed this scope of work and
recalculated the new quantities using updated unit prices (including material increases over the time
during the stoppage of work).
Cost: $542,635.00
Rail (guardrail): This is a credit to the project. This amount was included in Change Order#1, but is
credited back because it is now incorporated in the change order item above due to modified quantities.
Cost: $-28,750.00
Trail Realignment: This is a credit to the project. This amount was included in Change Order#1, but is
credited back because it is now incorporated in the change order item above due to modified quantities
associated with realignment of the trail a second time.
Cost: $-14,617.27
Contractor expenses during utility work: This item compensates the contractor for expenses during the
utility work while the work was stopped. These expenses include, security cameras, erosion control
replacement, and contractor hours spent checking on the site. Additionally,this includes the Project
Manager hours associated with assisting in pricing exercises,organizing site surveys, organizing
remobilization, etc.
Cost: $52,198.00
TOTAL:$524,998.23
