Body
Issue/Request:
An Ordinance approving Change Order No. 2 to the agreement for the construction of Project No. 718 Sidewalk Gap Phase 2 with Phoenix Concrete, LLC for an increase in the contract price of $90,135.00, for a revised agreement amount of $666,617.48 and authorizing the City Manager to execute an agreement for the same.
Key Issues:
• Pursuant to Ordinance 10238, the City and Phoenix Concrete, LLC (hereinafter "Contractor") entered into an Agreement for the construction of the Sidewalk Gap Phase 2, Project No.718, ("Base Agreement").
• The City and Contractor modified the Base Agreement, as amended, per Change Order No. 1 administratively in accordance with the City's Procurement Policy.
• The City desires to further modify the Base Agreement, as amended, due to added sections of sidewalk and additional costs associated with added work on Change Order No. 2 in order to complete the work.
Proposed City Council Motion:
FIRST MOTION: I move for adoption of Change Order No. 2 to the agreement for the construction of Project No. 718 Sidewalk Gap Phase 2 with Phoenix Concrete, LLC for an increase in the contract price of $90,135.00, for a revised agreement amount of $666,617.48 and authorizing the City Manager to execute an agreement for the same.
SECOND MOTION: I move for adoption of Change Order No. 2 to the agreement for the construction of Project No. 718 Sidewalk Gap Phase 2 with Phoenix Concrete, LLC for an increase in the contract price of $90,135.00, for a revised agreement amount of $666,617.48 and authorizing the City Manager to execute an agreement for the same.
Background:
The quantity (square feet) of driveways needed to properly tie-in driveways with the new sidewalks exceeded the original contract quantities. Adjustments were made based on the actual field conditions observed by the Inspectors, Contractor, and City project manager. Constructing new sidewalks across existing driveways almost always increases the slopes of driveways because a flat area of sidewalk that complies with ADA standards is inserted in the driveway that otherwise had a continuous slope extending from the back of curb. The extent of those driveway impacts is usually uncertain at the time plans are prepared and bid considering the limited level of design effort for this project. Sidewalk projects like this program are generally not surveyed and engineered for each and every driveway impacted.
During new sidewalk construction, the City tries to minimize driveway changes so that the property owner’s new driveway slopes are not significantly steeper after sidewalks are installed. To accomplish this, driveways are often reconstructed a reasonable distance beyond the sidewalk limits and the quantities to complete the driveway work are adjusted accordingly as a change order at the competitively bid price per unit of measure.
Sidewalk curb ramps are included in the scope of work as required for compliance with the Americans with Disabilities Act (ADA). Ramps require replacing curb adjacent to the new ramps, so this change order includes the increased quantities to replace curb and gutter quantities as those improvements were accommodated based on actual field conditions.
The amount of sidewalk with integral curb increased in exchange for reducing the amount of sidewalks with retaining walls where site conditions allowed. The shorter curb sections along the sidewalk were sufficient to match existing ground surfaces instead of the 1- to 3-foot-tall retaining walls shown in the plans. This project was able to add additional sections of sidewalk in areas of the Dalton's Ridge subdivision as a result of contract prices being well under the estimated budget. Added sidewalk sections to the contract resulted in increased quantity included in the change order.
These changes were owner-directed.
Impact/Analysis:
This project is expected to close remnant sidewalk gaps and will help to increase non-motorized mobility and pedestrian safety within neighborhoods throughout the City. After this change order, the two Sidewalk Gap projects will have spent about $3.2 million out of $5.0 million currently budgeted for new sidewalk construction (gaps). Future construction phases are planned to spend the remaining balances. The project is delivered on a design bid build process.
