Through: Michael P. Martinez, City Manager
Prepared By: Greg Labrie, Director of Public Works
Date Prepared: March 10, 2026
PURPOSE
Requesting City Council’s approval for the amendment of Denver Street Sidewalk and Drainage Improvements by amending the contract to D2C Architects, and approving the resolution giving the City Manager, or designee, authority to sign the contract amendment. Per City Code Section 3-8-170, “All change orders or amendments shall be processed through the Finance Department. Department directors shall have authority to approve individual amendments or change orders up to the department director’s aggregate signing authority for the total contract price. The City Manager shall have the authority to approve individual amendments or change orders, in the aggregate, up to the City Manager’s signing authority or up to ten percent (10%) of the original contract amount, whichever is higher. All other amendments or change orders shall be approved by the City Council, as appropriate, based on the signing authority established in this Article.”
BACKGROUND / HISTORY
The original Denver Street improvement project did not include certain components east of the existing railroad tracks. To address this, the project has been divided into two phases:
• Base Bid: Includes all improvements east of the railroad tracks, such as new sidewalk (matching original width), storm inlet and pipe connection, new curb and gutter, and additional asphalt patching.
• Alternate 1: Includes sidewalk west of the railroad tracks (matching original width). This work is contingent upon relocation of existing power poles.
The purpose of this amendment is to authorize extended design and construction administrative services for improvements along Denver Street, east of the rail spur, and to establish an allowance for additional work. This amendment ensures completion of project elements that were not constructed during the original phase.
FINANCIAL IMPACT
The basis of payment will be monthly billings based on the percentage of lump sum completed to date, including standard reimbursable expenses (mileage, travel, printing). Permitting fees are excluded. The amendment includes the following costs:
• Base Bid
o Construction Documents: $5,500
o Municipal Review Submittals: $4,500
o Bid and Construction Services: $2,500
o Project Closeout: $1,000
o Total Lump Sum Fee: $13,500
• Alternate 1
o Topset: $4,500 (Time and Materials; subject to prior approval)
The total potential financial impact is $18,000, with Alternate 1 contingent upon power pole relocation. This amount will not be exceeded without written authorization from the client.
STAFF RECOMMENDATION
Staff recommends that the City approves this amendment.
