| Present, Discuss, and Consider Action on a Resolution to Approve the Agreement for Professional Engineering Services Between the Town of Addison and Jacobs Engineering Group, Inc., for the Design of the Improvements to Keller Springs Road and Airport Parkway and Authorize the City Manager to Execute the Agreement in an Amount Not to Exceed $1,439,000.
|
This action will approve an agreement for professional engineering services with Jacobs Engineering Group, Inc., (Jacobs) for the design of the reconstruction and addition of the Master Transportation Plan elements to Keller Spring Road and Airport Parkway for an amount not to exceed $1,439,000. Keller Springs Road and Airport Parkway were included in Proposition A of the 2019 Bond Program election that the Addison voters approved on November 5, 2019.
The opinion of probable construction costs from the 2019 Addison Bond Program cost estimates as developed by Jacobs, is $8,719,650 for Keller Springs Road and $5,813,982 for Airport Parkway, totaling $14,533,632. This amount does not include the total project costs of $12.9M for Keller Springs Road and $9.4M for Airport Parkway, which includes costs for right-of-way acquisition and other soft costs, such as engineering, administrative costs, construction management, and materials testing. Jacob's design fee is $1,439,000, which equates to a fee percentage of 9.9% of the estimated construction cost. This is consistent with the percentages assumed for this service in the 2019 Bond Program analysis.
Staff recommends that the roads be designed at the same time to save the cost of remobilization for topographic surveying and sub-surface utility exploration services. Once designed, however, roads are not planned to be reconstructed at the same time.
On December 11, 2018 the Council approved a contract with Jacobs for the development of costs associated with the proposed street 2019 Bond Program. Given Jacobs familiarity of the projects, Staff recommends that they design the roadways.
The major scope items included in the design will be:
- Task A - Concept Studies and Preliminary Engineering
- Task B - Public Involvements
- Task C - Utility Coordination and Sub-Surface Utility Exploration
- Task D - Project Management
- Task E - Field Surveying
- Task F - Roadway Design
- Task G - Drainage
- Task H - Signage, Markings, and Signalization
- Task I - Miscellaneous Plan Development
- Task J - Traffic Control and Sequencing
- Task K - Illumination
- Task L - Environmental and Storm Water Pollution Prevention Plans
- Task M - Water and Wastewater Improvements
- Task N - Landscape and Aesthetic Improvements
- Task O - Quantities, Estimate and Specifications, and Bid Documents
- Task P - Bid Phase Services
- Task Q - Easement and ROW Acquisition
- Task R - Independent Design Review
Pending approval of the attached agreement, design for the roadways will begin as soon as Notice to Proceed is issued.
Funding for this work will be from the 2019 Bond Program funds. A reimbursement resolution is not required at this time but will be required before construction begins. Therefore, one will be brought to Council at the later meeting. |
