Attn: Rudy Koester, Public Works Director
Re: Change Order #004
Waukee Public Works Site Expansion Phase 1
Dear Mr. Koester:
Attached please find a detailed Change Order for City Council approval on July 24, 2023.
Change Description:
1. COR-014:
Sheet M2.1 – WEST WING FLOOR PLAN – MECHANICAL
a. Re-fabricate metal weatherhood for EF-1 to alleviate exhaust fan conflict with roof joist.
Sheet M2.2 – NORTH WING FLOOR PLAN - MECHANICAL
a. Re-fabricate metal weatherhood for EF-3 to alleviate exhaust fan conflict with roof joist.
Farnsworth Group’s Third Amendment reduces their contract by $2,610, which offsets the
additional $2,609.25 incurred by the City of Waukee.
2. COR-015:
Sheet C101 – SITE PLAN
a. Per the request of City Staff, contractors pumped the concrete pavement, so concrete
trucks did not rut and deteriorate the stability of the subgrade. Additional cost of
$18,355.80 was negotiated by City Staff.
3. COR-016:
Sheet C101 – SITE PLAN
a. Construction documents required the contractors to raise existing vault to grade.
Construction activities damaged the existing vault. City staff installed a casting ring in
lieu of re-installing the non-traffic rated vault in the concrete pavement. Core agreed to
provide a deduct of -$1,634.28 for not being required to replace the damaged vault.
4. COR-017:
Sheet C201 – GRADING PLAN
a. Grading revisions were required in the far northwest corner of the property where no
new grading was indicated to prevent ponding or diverting water onto neighboring
properties. The additional cost was $2,524.05 for additional labor and equipment costs.

Page 2 of 2
5. COR-018:
Sheet A1.4 – NORTH WING FLOOR PALN
a. City staff determined they will not be storing the MDPE gas pipe in the building as
originally planned. Therefore, the 4” paint stripping was omitted from the project. This
resulted in a deduct of $-$1,881.40.
6. COR-019:
Sheet C101 – SITE PLAN
a. City staff identified a 16 SY area of existing concrete damaged during construction by
City staff. Core agreed to replace pavement for an additional cost of $613.44.
7. MidAmerican Energy Billing Reimbursement:
a. The permanent power was energized, and the billing was changed to the City of Waukee
while still providing power during construction. Core agreed to reimburse the City of
Waukee for the June bill. Since the July bill has not been sent, City staff recommended
doubling the June bill to cover the anticipated cost for July. This results in a deduct to
the contract of -$442.00.
We have reviewed the submitted Change Order Requests (CORs) from Core Construction, and the
Design Team considers them to be in line with current industry pricing. If City Staff concurs with these
proposed additional costs, then we recommend the City of Waukee Increase the contract price in the
amount of $20,144.86 to complete the additional work associated with Change Order Number 004. If
you have any questions, please contact me.

Jeremy,
The wall openings for EF1 & 3 are at the same elevation as the roof joists. Inside the wall there is very little clearance
between the wall and roof joists.
The exhaust fans will have to be mounted further thru the wall to the outside. The weather hoods will not cover the
fans.
Deeper weather hoods can be built to cover these fans.
The additional cost is $2450
Thanks, Gayle

Question Question from Jeremy Roush Core Construction on Monday, Apr 3, 2023 at 03:05 PM CDT
Drawings indicate to raise one existing vault to grade with paving/utilities
There are actually two Vaults and one was damaged over the winter by construction traffic.
We will replace with similar box however the existing Vault is only rated for 15,000 #’s
Should we replace both vaults with 24’000 vaults as they are in a high traffic location?
