Project consists of lining 556 LF of 42 inch CMP and 131 LF of 15 inch RCP with CIPP.  Eight existing drainage structures will be removed and replaced and two additional structures will be added. 221 LF of 15″ RCP will be removed and replaced. Chemical grouting joint repair will also be installed at approx. 15 locations throughout the 42″ CMP.

The purpose and need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality. The project area is located in the overall Sunnyvale Storm Drainage Improvement Project (SDIP) area. The scope of work for the Tyndale Avenue project includes replacing a corrugated metal pipe between Tyndale Avenue and Chandworth Road. Replacement of the system is needed to address reported house flooding in the immediate area. The upgrade to the system also allows for the construction of the upstream improvements currently in design from the Storm Water’s queue that will address seven requests for service of failing infrastructure and flooding requests. Approximately 500 linear feet of 48-inch to 66-inch corrugated pipe will need to be replaced to address the undersized and deteriorating system in the Severn Avenue project area.

This project consists of two culverts in series under Cedarbrook Drive and Denbur Drive. Both culvert crossings consist of triple barrel corrugated metal pipe systems. This is a project that was identified by the asset management team and both culvert crossings are actively failing, and preliminary calculations show that the culverts are also undersized.

Collective Storm Drainage Improvement Projects Series AG will involve 2 projects throughout the City of Charlotte, 1845 Pinewood Cr and 6009 Rexwood Pl.  1845 Pinewood Cr will consist of reinforced concrete pipe replacement and realignment, CIPP liner, storm drainage structure replacement, full depth asphalt, curb and gutter, concrete driveway, new sanitary sewer pipe and sanitary sewer structures, and new watermain.  6009 Rexwood Pl will consist of reinforced concrete pipe replacement and realignment, CIPP liner, storm drainage structure replacement, full depth asphalt, curb and gutter, and concrete driveway.

The project is located at Robert L. Smith Park which can be accessed by Little Rock Road and Starnes Road. An existing pond has a breached dam embankment. Project improvements include dam embankment, forebay, outlet structure, and spillway upgrades.

The purpose and need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality.  This project is under review.  Location and project details will be provided after the review is complete.

Work performed under this contract will consist of storm water infrastructure repair and improvement projects within the city limits of Charlotte, NC.  Work will involve mobilization, earthwork, drainage structures, storm drain pipe systems, and channels. Work could also include working over, under, near, and around existing private utilities, asphalt paving, concrete flatwork, landscaping and any associated work required by the Engineer.  Other work may include structural foundation protection, storm water pipe lining, storm water pipe joint and structure repair, water and sewer (relocations, installations and adjustments).  Storm Water maintenance work may be located entirely within the street right-of-way or within storm drainage easements.

The Gleneagles Project is primarily focused on replacing an existing CMP culvert near 3810 Gleneagles Road.  The existing culvert is 8.7’ high by 7.8’ wide and is being replaced with a 10’ wide and 7’ tall RCBC.  The culvert replacement is occurring to address aging infrastructure and to improve the reliability of infrastructure for the traveling public.  In support of this culvert replacement, we are dredging the downstream pond which is located on the Quail Hollow Country Club near the 15^th hole.  The dredging will remove sediment that has built up near the downstream end of the existing culvert and prevent sediment transport downstream which would negatively impact existing ponds and habitats.  In addition, we will be adding inlets and upgrading roadside drainage on Out-Of-Bounds Drive which has significant spread in larger storm events from road drainage.  The work on Out-Of-Bounds Drive will increase the safety of the traveling public using that roadway during rain events.

This contract is for guardrail installation and repairs on various roads within the City of Charlotte, as needed and upon request. The Engineer and or designee will identify locations requiring guardrail maintenance and repair throughout the city. The extent of maintenance and repair will vary based on the amount of existing or damaged guardrail along each route, and bidders should consider this when submitting a bid.

During maintenance and/or repair of damaged sections of guardrail, the contractor shall replace all needed components of guardrail as directed by the Engineer and stabilize existing guardrail and appurtenances at the site.

All work and materials shall be in accordance with the provisions of the General Guidelines of this contract, the Project Special Provisions, the North Carolina Department of Transportation Standard Specifications for Roads and Structures, January 2024, the North Carolina Department of Transportation Roadway Standard Drawings, January 2024, and the current edition of the Manual of Uniform Traffic Control Devices (MUTCD).
