Per your request, Schrickel, Rollins and Associates (SRA) has reviewed eight
separate letters sent to the City from Infrastructure Services Inc. (ISI) dated August 14,
2002. In these letters, ISI requests additional compensation for extra work performed for
the referenced project. We have numbered the letters herein for reference purposes.
The first five letters request additional time and money for issues related to
construction phasing:
Letter No. 1:
Temporary Roads
$14,286.53
Letter No. 2:
General Conditions
$52 9 620.37
Letter No. 3:
Barricade Maintenance
$9
Letter No. 4:
Concrete Labor Inefficiency
$30,081.23
Letter No. 5:
Extra Mobilization
$23,332.84
In our opinion, no construction phasing work was required by the City beyond the
scope as defined in the Bid Documents. The description for Traffic Control (Bid Item No.
127) states that, "Unless otherwise approved by the owner, two -way traffic shall be
maintained on all roadways under construction at all times. No special, extra, unit or
otherwise separate payment shall be made for this purpose regardless of the number,
duration or other variations for the Contractor's barricades and sequencing unless the
contract scope is changed following the receipt of bids." It is our understanding that the
Contractor was not instructed by the Owner to phase the project in any way.

Letter No. 6: Extra Excavations $18,041.01
This letter states that: "ISI was required to relocate the stockpile, previously
relocated, and cut out the existing berms to install the corrected sidewalk." There are two
separate issues involved in this request. The first issue is the stockpile. The Contractor
was required per Addendum No. 1 to relocate, "Only the portion of the stockpile that is
located within the Creekview Drive project limits ". The stockpile was relocated during
initial excavation, but only to the north right -of -way line, not the north limits of the
project. The project limits include the sidewalk which is shown on the bid documents at
approximately 40f feet north of the right -of -way line. The redesign of the sidewalk
moved the sidewalk to within l0± feet of the right -of -way. The second issue concerns
additional excavation required at the two berms between Sta. 22 +00 and Sta. 26 +00
( Creekview Drive) for the sidewalk construction. Chris Schnitger (SRA) and Philip
Bennett (ISI) discussed this work and it was agreed to be paid at the unit price bid for
Unclassified Roadway Excavation (Bid Item No. 102). It was our understanding that the
additional excavation was to be utilized on -site as backfill for the parkway and
construction of the 6 -foot sidewalk. hi our opinion, no additional work was required on
the stockpile beyond the project scope as bid. In regards to the second issue, we do
recommend payment for the additional excavation (333 CY) at the unit price bid (Item
No. 102) per discussion with ISI personnel.
Letter No. 7: Excess Dirt Haul Off -site $68,121.98
This letter claims that ISI was told by SRA that disposal of materials would be
allowed on site. Addendum No. 1 clearly states: "Excess material will need to be
disposed of off -site unless otherwise specified by the Owner ". At no time did SRA
indicate that Addendum # 1 did not apply.
In our opinion, no additional work was performed beyond the scope as specified
in the Bid Documents.
Letter No. 8: Stock Pond Work $17,894.95
This letter requests money and time for the removal of trees and the placement of
fill dirt. According to the construction plans approximately half of the stock pond
required fill material and tree removal in order to construct Freeport Parkway and the
required grading. It is our understanding that the remainder of the stock pond was filled
(with Owner permission) by the Contractor for his convenience to reduce material to be
removed from the site. The additional tree removal was caused by the Contractors use of
the property to dispose of excess excavation.
In our opinion, no compensation is due for the additional work performed beyond
the scope as specified in the Bid Documents.
