Title
Consider Authorizing The City Manager To Approve A Contract With 3D Paving And Contracting, LLC For The Nob Hill Addition Section 1 Street Replacement Project In An Amount Not To Exceed $4,779,864.00.
Body
BACKGROUND:
The Nob Hill reconstruction project is part of the 2013 bond program. The neighborhood poses a unique situation for design and construction because of multiple large retaining walls on private property. The project has been sequenced so that the section 1 reconstruction project does not contain areas with the larger retaining walls. The overall Nob Hill reconstruction project consists of three phases: alleys, section 1, and section 2. The alley phase has been completed with the exception of one alley that has a large retaining wall on private property.
This contract provides for the reconstruction of nine streets in the Nob Hill section 1 phase, including Spyglass Drive, Spyglass Court, Railhead Place, Reunion Circle, Haney Street, Lookout Place, Gold Rush Lane, Station Place and Indigo Court. The project consists of the reconstruction of approximately 6,180 linear feet of pavement, 5,000 linear feet of water mains and 5,300 linear feet of sanitary sewer mains.
The duration of construction is 450 calendar days. Construction will be performed such that all of the streets will not be under construction at the same time. Project signs will be placed at the entrances to the subdivision while it is under construction. All residents will be notified in writing regarding the construction schedule prior to the start of work. Also, a neighborhood meeting with the homeowners and the contractor will be held prior to construction. Additional handouts will be distributed as required during the project.
Due to the complexity of the retaining walls, staff and the design teams sequenced the reconstruction project in early 2022 so that all of the major retaining walls would be included in the section 2 phase of the project. In February 2022, City Council approved a contract amendment to provide an in-depth engineering and structural analysis of certain retaining walls. Once the review is complete, staff will determine a construction schedule for section 2.
FINANCIAL IMPLICATIONS:
Seven (7) bids were received on October 26, 2022. The low bid, in the amount of $4,779,864.00, was submitted by 3D Paving and Contracting, LLC. The engineer’s estimate for the project was $5,640,000.00. 3D Paving and Contracting has performed numerous projects in Carrollton, most recently the Northcrest Estates Sections 1 and 2 NOTICE project and the Green Ridge/Myerwood street reconstruction project. Funding is available in the Streets Consolidated account.
IMPACT ON COMMUNITY SUSTAINABILITY:
This project will support the City Council’s strategic objectives and vision of building a community that families and businesses want to call home by:
- Sustaining quality of life - Improvements in the subdivision should improve the appearance of the neighborhood and promote residents to provide ongoing maintenance of their properties.
- Sustaining day-to-day operations - The replacement of substandard street pavement, water and sewer lines should reduce the need for non-scheduled or emergency repairs.
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommends that City Council authorize award of the construction contract for the Nob Hill Addition Section 1 Street Replacement Project to 3D Paving and Contracting, LLC in an amount not to exceed $4,779,864.00.
