(Contract No. 2022-0407-X; Modification No. 3) Approved |
| | | | | | | | PREVIOUS ACTION/PRESENTATION On April 25, 2022, City Council approved an engineering professional services agreement in the amount of $431,201 for the Intersection Improvements - 14th Street & Shiloh Road, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Project No. 7458 to Lamb-Star Engineering, LLC.
On April 10, 2023 City Council approved Modification No. 2 to amend the scope of services. Modification No. 2 increased the total amount by $371,649 for a total contract amount of $802,850. This modification also amended the contract time to 1045 Calendar Days and amended the project title to Intersection Improvements - 14th Street & Shiloh Road, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Corporate Drive at Tennyson Parkway & Legacy Drive, Legacy Drive at SH 121. |
| | | | | | | | BACKGROUND The Engineering Department recommends approval of Contract Modification No. 3 for the increase in the engineering professional services agreement with Lamb-Star Engineering, LLC, in the amount of $157,406, for the Intersection Improvements – 14th Street & Shiloh Road, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Corporate Drive at Tennyson Parkway & Legacy Drive, Legacy Drive at SH 121.
Contract Modification No. 3 includes intersection improvements at three (3) additional intersections to include the addition of turn lanes, pedestrian, and safety improvements at HAL-HARS prioritized intersections:
1. Plano Parkway & Julliard Lane - left turn lane for U-turn
2. SH 121 & JP Morgan Chase Driveway (Northbound Frontage Road) - extension of existing turn lane
3. Cheyenne Trail & Spring Creek Parkway - pedestrian ramps and pork chop island
In addition, Engineering would like to request a change in project name from "Intersection Improvements – 14th Street & Shiloh Road, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Corporate Drive at Tennyson Parkway & Legacy Drive, Legacy Drive at SH 121" to "Intersection Improvements - Cheyenne Trail & Spring Creek Parkway, Plano Parkway & Julliard Lane, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Corporate Drive & Tennyson Parkway, Corporate Drive & Legacy Drive, Legacy Drive & SH 121, SH 121 & JP Morgan Chase Driveway (Northbound Frontage Road)". The 14th Street & Shiloh Road location was incorporated into the Shiloh Widening project so that scope is not in this plan set anymore.
Engineering will be changing the Project No. from "7458" to "ENG-S-00003" due to internal software changes.
Contract Modification No. 1 was executed on February 21, 2023 to amend scope of services and was a no-cost modification.
The request for this modification amount is adjusted for rounding. The current contract amount is $802,849.50 with an increase of $157,405.65 for a total contract amount of $960,255.15.
If this contract modification is not approved, it would result in increased traffic delays and continued safety concerns with turning movements, leading to a reduction of vehicular safety and a decrease in quality of life for citizens and motorists. |
| | | | | | | | FINANCIAL SUMMARY/STRATEGIC GOALS Funding for this item is budgeted in the 2024-25 Street Improvements CIP. The third modification to the professional services agreement for the Intersection Improvements - 14th Street & Shiloh Road, 14th Street & Plano Parkway, Parker Road & Archerwood Street, Corporate Drive at Tennyson Parkway & Legacy Drive, and Legacy Drive at SH 121 project, in the total estimated amount of $157,406, will leave a current year balance of $18,828 available for future expenditures.
Approval of this item will support the City's Strategic Plan Critical Success Factors of being an Excellent, Innovative, and Accountable City Government. |
