Exhibit 1 - Agenda Information Sheet - Change Order 4City of Denton _____________________________________________________________________________________ AGENDA INFORMATION SHEET DEPARTMENT: Procurement & Compliance ACM: David Gaines DATE: August 10, 2021 SUBJECT Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation, authorizing the approval of Change Order No. 4 to the contract between the City of Denton and Quality Excavation LTD, for construction of the McKinney Street sidewalk segment for the Downtown Storm Sewer Trunk Line PH I Project; providing for the expenditure of funds therefor; and providing an effective date (IFB 7086 – Change Order No. 4 in the not-to-exceed amount of $102,451.25, for a total contract award aggregated to $1,218,908.25). INFORMATION/BACKGROUND The Downtown Storm Sewer Trunk Line improvements project was created to address flooding in the downtown Denton area. Specific areas of concern are near the intersections of the Union Pacific Railroad and McKinney, Oak, Hickory, Mulberry and Sycamore streets. Phase I of the project consists of the improvements from McKinney to Hickory along the UPRR ROW plus the improvements on Oak Street. The original project total cost of $1,141,102.20 for Downtown Storm Sewer Trunk Line PH I construction consists of: $1,086,764.00 total base bid; and a $54,388.20 contingency. Change Order #1 was a negative change in the amount of -$4,710.00 due to the removal of split-casing intended to protect an existing sanitary sewer and the addition of three (3) junction boxes that were missed on the bid quantity tabulation. Change Order #2 depleted the full contingency amount of $59,048.20, plus an additional $19,121.80 to cover changing the 5” parking lot paving to 7” thick to match the existing conditions. Also, additional sidewalk was removed/replaced along McKinney and additional connections were required to the 6’x6’ box to ensure that all drainage was connected. Change Order #1 was executed adding the negative amount back into the original contingency in error resulting in an higher contingency amount for Change Order #2. Change Order #3 was another negative change order in the amount of $43,767.00 for the reduction in parking lot paving due to difference of survey and estimated quantities, and removal of unnecessary items due to a change in the project plans and field conditions. Additional items included a TxDOT inlet due to conflict with existing utilities and a change in water line lowering from 6” to 8” sanitary sewer pipe. This is the fourth change order for this project. This change order is the result of adding a segment of the 2018 Sidewalks Improvement Project along McKinney due to overlap in both the scope and work area. Adding the sidewalk to this project resulted in a savings of approximately $22,548.75 as compared to City Hall 215 E. McKinney Street Denton, Texas www.cityofdenton.com performing the sidewalk improvements as a separate project. Having a single contractor perform the work will also result in less congestion along McKinney Street.
