AGENDA INFORMATION SHEET

DATE: May 3, 2022
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the approval of Change Order No. 3 to the contract between the City of Denton and Quality
Excavation, LTD, for additional work on the 2019 Intersection Improvements Project; providing for the
expenditure of funds therefor; and providing an effective date (IFB 7413 – Change Order No. 3, in the not-
to-exceed amount of $309,521.05, for a total contract award aggregated to $2,119,091.68).
INFORMATION/BACKGROUND
The 2019 Intersection Improvements project was created to address traffic safety concerns at the following
intersections: Nottingham Drive and US 380, McKinney Street and Loop 288, Locust Street and Hercules
Lane, McKinney Street and Woodrow Lane, and Sherman Drive at Loop 288. This project includes signal
installation and turn lane additions with pavement repairs to increase traffic safety needs at the locations
listed above. The City entered into a contract with Quality Excavation, LTD on December 1, 2020, to
complete the 2019 Intersection Improvements Project.
Change Order No. 1 totaled $25,531.54 and was approved administratively on July 12, 2021. This change
order covered additional quantities due to utility conflicts, new items required by conflicts encountered in
the field, modifications associated with existing pavement conditions at the connection points, and added
21 days to the schedule.
Change Order No. 2 totaled $60,590.36 and was approved administratively on October 04, 2021. This
change order covered additional quantities at Sherman/Loop 288 for flex base, barricades and signs, new
ADA ramp items, and added 55 days to the schedule.
Change Order No. 3 (Final Change Order) in the amount of $309,521.05, with $48.13 of contingency funds
being held. The change order addresses safety concerns at Sherman Drive at Loop 288 that arose after the
construction was completed. The safety concerns are due to utility conflicts found in the field that resulted
in design changes that had to be made that were not in the original scope of work. These changes and safety
concerns had to be evaluated between City staff and TxDOT in order to be resolved. The original scope of
the project was completed in October of 2021. Due to these concerns and material delays the project has
been delayed, the remaining items that address the safety concerns can be completed in 30 days upon
approval of the change order. This is the reason for the extension of the days to the project. The original
contract time has to be extended to allow the safety concerns to be addressed. The following items are
included as part of Change Order #3:
City Hall
215 E. McKinney Street
Denton, Texas

Changes to existing and new items include:
• Additional roadway excavation on multiple sites
• Extended use of traffic control devices
• Additional quantities associated with Single Slope Traffic Rail (SSTR)
