Analysis of Issues
. Change order specifics
The two largest change orders are the soil corrections in lot 500 ($30,674.75)
and additional gravel required due to not reclaiming the asphalt from lot 500
($23,114.00). Regarding the soil corrections, the two soil borings from lot 500
did not reveal the extent of poor soils encountered. The additional excavation
and gravel prices did not exceed the bid prices. In fact, the contractor agreed to
a $3,000 reduction in these costs due to the increased quantity of work. The
additional cost incurred by not reclaiming the lot 500 asphalt was necessary to
maintain adequate open parking areas during construction and to maintain a
reasonable construction schedule. An explanation of each change order item is
included with the attached change order form.

Description: Additional Cost Required for Soil Corrections in Lot 500 & 600, Cost
Associated to Abandoned Oil Tank in Lot 500, Additional Costs Required for Stonn
Sewer Installation, Reduction in Mobilization Due to Constructing Lot 600 in One Phase,
Additional Gravel Required Due to Removing Pavement Instead of Reclaiming (Due to
Scheduling Issues), Additional Excavation Due to Moving Storm Sewer Location North
of Alley and Changing Grade of Parking Lot, High Early Concrete Additive to Provide
Access for Driskill's, Mulch Piaced in Tree Boxes and Around Two Large Trees West of
Lot 600, Compensation for Grading 10th Ave., Business Access Signs, Grate
Replacement in Pedramp Located on 11th Ave., Reduction in Payment for Damage to
Kurt Rolf's Garage Floor, Traffic Control Conduit Replacement, Cutting Tree Grates,
Sidewalk Removal in front of Center Drug, and Additional Electrical Improvements.
. Reasons for Change Order:
The Additional Cost Required for Soil Corrections in Lot 500 & 600: During
excavation efforts in Lot 500 & 600 unsuitable" soil containing organic material was
discovered. In order to insure a solid subbase the undesirable soil was excavated and
replaced with gravel. The result of the soil corrections is a more solid, longer lasting
parking lot surface.
Cost Associated to Abandoned Oil Tank in Lot 500: During the excavation of Lot 500
an abandoned oil tank containing service drain oil was discovered. The tanl<. was
considered a hazardous material and was removed according to Minnesota State
regulations. Mimlesota Petrolewn Services removed the hazardous materials and the
tank.
Additional Costs Required for Storm Sewer Installation: The storm sewer system was
modified during the course of the project. The changes resulted in an overrun in the
original pipe lengths and storm structures quantities. The changes resulted in a better
more efficient storm sewer system.
.
. Reduction in Mobilization Due to Constructing Lot 600 in One Phase: The phasing
schedule for Lot 600 changed during the course of construction. Originally Lot 600 was
going to be constructed in two phased in order to increase parking in the area during the
project. After discussing the phasing schedule with local businesses and considering the
additional time required to reconstruct the lot in two phases a decision was made to
construct the lot in one phase. This decision saved DMJ (contractor) time and money,
which resulted in a reduction in mobilization costs.
Additional Gravel Required Due to Removing Pavement Instead of Reclaiming (Due
to Scheduling Issues): The scope of the proj ect changed during the course of
construction increasing the required gravel quantity. Originally Lots 500 & 600 were
going to be reclaimed, meaning that the existing asphalt would be reused as gravel.
During the course of the project the decision was made to remove the asphalt in both
parking lots and use gravel from an outside source. The reason for this decision was
based on the thickness of the asphalt in the parking lot, scheduling issues, and quality of
finished product. The asphalt in the parking lots was very thin in several places making it
unfeasible to reclaim. The scheduling for the reclaiming would have held up the project.
Replacing the gravel versus using reclaim provides a better-finished product.
Additional Excavation Due to Moving Storm Sewer Location North of Alley and
Changing Grade of Parking Lot: The location of the storm sewer in lot 500 was moved
from the curb along the south end of lot 500 to 30 feet north of the curb. The change in
. sewer location resulted in a grade change in lot 500 that increased the amount of required
common excavation. The result of this decision eliminated the risk of \vater pooling in
front of the buildings facing Lot 500 on the south side during a heavy rainfall.
High Early Concrete Additive Required to Provide Access fo.' Driskill's: The use of
high early additive reduced the required curing time of the concrete poured for Driskill's
truck access apron from 7 to 3 days. Driskill's food receives deliveries on a daily basis
and could not wait 7 days between shipments.
I
J\1ulch Placed in Tree Boxes and Around two Large Trees \Vest of Lot 600: The
scope of the landscape plan changed due to the hvo tree boxes placed on 11 th Ave and the
removal of tree grates around the hvo Imge trees west of Lot 600. Additional mulch was
required along "vith compensation for the additional work.
Compensation for Grading 10th Ave: During the construction of 10th Ave a decision
was made to keep the existing gravel in place versus excavating the street to sub grade
and hauling in new gravel. This decision was made after consulting a geotechnical
engineer in an eff0l1 to reduce the cost of the project. The overhead expense for grading
the street was included in the price of the gravel. Additional compensation was required
for grading 1 otll Ave due to the reduction in gravel required to reconstruct lOth Ave.
.
. Business Access Signs: At the start of the project many business owners in the area
where concerned of the impacts to their business due to the construction. A major
concern was that people would not Imow how to access their businesses. In order to
reduce confusion and increase business, signs were made that directed traffic to the street
that provided access during each phase of the project.
Grate Replacement in Pedramp Located on 11111 Ave: TIle grate located in the
pedramp located on 11 th Ave. was replaced at the request of the city in order to provide
better drainage and reduce maintenance.
Reduction in Payment for Damage to Kurt Rolf's Garage Floor: The drive apron in
front of Km1 Rolf s garage was replaced as part of the project. Dming the process of
removing the existing drive apron and pouring new concrete several new cracks were
formed in the garage floor slab. DMJ and their concrete sub-contractor both refused to
look into the mater leaving the city responsible for repairing the damage caused during
the construction efforts. A decision was made after access tbe damage to retain moneys
in order to have an outside contractor repair the cracks.
Traffic Control Conduit Replacement: During tbe asphalt removal of 10111 Ave the
conduit for the traffic control was damaged resulting in the traffic signal to be inoperable
for approximately thTee weeks. The conduit was replaced according to the requests of the
. city. A decision was made to pay half of the price of replacing the conduit under the bid
prices set by the contract. The compromise in price was made because the existing
conduit was working and did not need to be replaced, but the new conduit system is
installed to code while the existing conduit system was not.
Cutting Tree Grates: The new tree grates installed around two existing trees in Lot 600
had to be cut in order to fit around tile trees. DMJ requested additional payment to
compensate for their time spent cutting the tree grates.
Sidewalk Removal in front of Center Drug: TIle existing sidewalk in front of Center
Drug was 13 inches thick and required additional work in order to be removed.
Additional payment \vas made to compensate for the additional time required to remove
the sidevvalk.
Additional Electrical Improvements: During the course of the construction project
additional electrical work \vas warranted to improve the street light electrical wiring.
