TO CONTRACTOR: American Empire Builders, Inc.
The Contract is changed as follows:
The original Contract Sum ........................................................................................$5,260,000.00
Net change by previously authorized Change Orders ................................................................ $0.00
The Contract Sum prior to this Change order was...........................................................$5,260,000.00

Additional time, labor and equipment was necessary for the contractor to construct a temporary guardrail system to
replace a concrete guardrail system that was specified in the contract documents. This work added 12 Contract
Days and an increase of$3,933.75 to the original contract.
As a result of delays of behalf of utility companies to remove and relocate their utility service lines to new poles, the
contractor needed to adjust their construction sequences resulting in an increase of 31 Contract Days at no
additional cost to the original contract.
The contractor needed to remove large concrete pads that were constructed to support the original bridge structures
and were not shown on the Contract Plans. The concrete pads were not discovered until entire lane demolition was
complete and removal was necessary to complete the sheet pile and end bent installations as a part of this contract.
This additional work added 14 Contract Days and an increase of$17,600.64 to the original contract amount.
The total amount of this change order is$21,534.39 and adds 57 days to the original contract.
This change order no. 1 revises the substantial completion date to September 4, 2024.

Subject: Change Order#001
A. Installation of Temporary Guardrail in lieu of Barrier Wall
B. Existing Utility Pole Conflict
C. End Bent#1 Unforeseen Conditions
Dear Mr. Briggs:
WSP has received American Empire Builders, Inc(AEB) request for additional compensation due to Installation of
the Temporary Guardrail in lieu of Barrier Wall, Existing Utility Pole Conflict, and End Bents 91 & 92 unforeseen
conditions.
A. AEB needed to use existing material from the previous bridge strengthening project to construct the
Temporary Guardrail for Phase 2 of the Construction Sequence. The sequence of construction events was
affected, and additional time, labor and equipment was necessary. AEB is requesting 12 Contract Days and
a$3,933.75 payment. This requested Time and Cost also includes a credit from the proposed construction in
the Bid documents and Contract.
B. AEB needed to adjust their construction sequence due to an existing Utility Pole removal date delay. This
Utility Pole conflict was initially brought up during the preconstruction meeting and removed at a later date.
AEB is requesting 31 Contract Days and a $0 payment. This amount of Time and Cost was the negotiated
and agreed upon amount of impact on the critical path witness by the Utility Pole conflict delay.
C. AEB encountered large amounts of concrete that had been placed to support the existing bridge.This concrete
impacted the contractor's ability to remove the existing foundations and drive the permanent sheet pile per
plan in the phase two construction of the bridge. AEB is requesting 14 Contract Days and a $17,600.64
payment for labor and equipment to complete this task.
The total amount of the work order is $21,534.39 and 57 Additional Contract Days. WSP concurs with this
additional compensation for the three requests as supported by provided documentation.
Should you have any questions,please contact me 305-393-2185.
Sincerely,
WSP
