RE: Change Order—Concealed Fire Damage
City of Ukiah's Electrical Service Building at 1350 Hastings Rd
Ms.Horger,
Please find our costs and justifications for providing additional structural repair design for the second story and
construction assistance for the City of Ukiah's Electrical Service Building.
Whitchurch Engineering provided a cost estimate to assess damages caused by the fire and prepare plans to correct
damages and potential causes of the damages. The contract included an assumption (Assumption #3), that
significant fire/water damage was not concealed by sheetrock during the March 281h, 2023 Site Visit. During
demolition, by Kirby Construction, fire damage was discovered, which impacted the collecting girder truss at the
building corner.Damage was such that repair or replacement was necessary. Whitchurch Engineering,as requested
by Cindy Sauers, prepared a structural design to repair the existing truss, in order to avoid further construction
delays.An issued for construction design was transmitted to the City and Contractor on July 191,2024.
In addition to the out-of-scope work identified above,Whitchurch Engineering notified City of Ukiah on August 3O'h,
2024 that the scope of the construction services contract was complete, per the assumptions agreed upon in the
contract dated September 201, 2022.Starting September V, 2024,Whitchurch Engineering proposes to continue
supporting the project on a Time and Materials basis, up to the estimate provided in this letter. An estimate has
been included, given the number of RFI's transmitted since August 3O111, 2024, the duration of the remaining
construction schedule,and an estimated number of RFI's still to be sent.
The additional cost requested is$11,884.25.A full description of services and breakdown of hours is provided on
the attached page.
Should you have any questions regarding the changes and additional fees,please don't hesitate to contact our office.
Sincerely,
Jeffrey Laikam,PE
