Title
Authorize the City Manager to finalize and execute Change Order No. 2 to Bid No. 2019-038, Stream Bank Stabilization and Bridge Replacement Project South Mesquite Creek, with Coppell Construction Company for payment of contract incentives and changes in construction scope in the amount of $213,697.80.
Body
The City Council approved the original construction contract with Coppell Construction Company, Inc., on January 7, 2019. This construction project provides improvements to stabilize and improve a section of South Mesquite Creek between Town East Boulevard and Towne Centre Drive. The project will lower flooding elevations and reclaim land from the 100-year floodplain including the athletic fields at North Mesquite High School. These drainage improvements included the reconstruction of the bridge on North Mesquite Drive and relocation of a dual large diameter sanitary sewer main.
The original contract amount as initially awarded was $5,574,776.20, with 330 calendar days for completion of the project.
Change Order No. 1 was approved by the City Manager on June 4, 2019, in the amount of $22,000.00. This change order was requested by the Mesquite Independent School District (MISD) for extra grading for a planned MISD soccer field. MISD agreed to pay the full amount of this change order.
Change Order No. 2 is in the amount of $213,697.80 for the following:
• Incentives for meeting the project milestones as dictated by the project documents.
• Changes to the retaining wall structure along the creek next to the ballfield outfield.
• Changes to the relocation of two large sanitary sewer mains in the ballfield to a single larger sanitary sewer main that is largely in the creek, outside of the ball fields.
• Relocation of a 14-inch diameter North Texas Municipal Water District water main in the creek that was in conflict with the drainage channel and bridge construction.
Attached is a detailed itemized listing of the changes to the bid items and addition of new bid items to cover the change in scope of the construction project. The project has met all contract milestones with all major items of construction now completed. Minor grading, re-establishment of vegetation and cleanup are still underway and must be completed prior to final payment.
Financial Implications
Sufficient funds are available in the project budget to accommodate this change order.
