Letter of Recommendation PREPARED BY:Beth Richardson REVIEWED BY:Sara Kappos SKK PUBLIC NOTICE INFORMATION – NAME OF PUBLICATION: DATE OF PUBLICATION: I1G3 ENGINEERS | ARCHITECTS | SURVEYORS | SCIENTISTS 14225 University Avenue, Suite 110 Waukee, Iowa 50263 p 515.225.3469 www.f-w.com July 17, 2023 City of Waukee 805 University Avenue Waukee, Iowa 50263 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. City of Waukee July 17, 2023 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. Sincerely, FARNSWORTH GROUP, INC. Kristofer J.
