The project includes rehabilitation of the one manhole and new construction of four manholes. Demolition and abandonment includes removal of 200 feet of 54 inch reinforced concrete pipe at the Boggy Bayou crossings, and abandoning in place one manhole and the remaining 1,172 feet of existing pipe.

North Pierre Lift Station Roof Repair

The project scope for the North Pierre Lift Station Roof Repair will be to selectively demolish existing electrical, HVAC and plumbing work on the roof, and remove all existing roof and plywood decking. Water damaged roof framing will also be removed. After removal of all damaged material new roof sheathing, standing seam metal roof panels, and new
lighting fixtures will be installed.

Stoner Lift Station

The Stoner Lift Station Emergency Repair Project requires the contractor to make necessary repairs to the collapsed pipe upstream of the existing lift station as shown in the construction documents. The work includes removal and replacement of existing 48 inch gravity sewer main, dewatering, trench, shoring system, helical support piles, structural concrete pile caps, bypass pumping and miscellaneous items.

North Regional WWTP Levee Repair #1

The North Regional Wastewater Treatment Plant (WWTP) Levee Repair Project encompasses the repair of approximately 15,000 square feet of levee slope on both the exterior and interior of the levee. The project also includes drainage ditch grading, the raising of a water valve vault lid, and a sanitary sewer manhole rim.

North Regional WWTP Levee Repair #2

The Levee Repair #2 project at the North Regional Wastewater Treatment Plant encompasses the repair of approximately 2,700 square feet of levee slope on the bayou side of the levee to address erosion issues that have occurred.

Lucas & North Regional WWTP UV Disinfection Improvement

The project involves the replacement of the existing UV disinfection equipment at both the Lucas and North Regional wastewater treatment plants to address and enable the facilities to continue maintenance issues properly disinfecting the wastewater.

Exposed Sewer Mains in Bayou Pierre Sewer Main

 The project involves protection of two exposed sewer mains in Bayou Pierre by removing and replacing the existing failed concrete encasement or lowering the mains beneath the ditch line.

Sludge Farm Facility Improvements

The Sludge Farm Facility Improvements Project includes the installation of a new 800,000 gallon wastewater storage tank on a concrete foundation along with the associated valves, piping, pumps, and electrical. The project also includes the rehabilitation of
the existing wastewater tank.

Southern Trace Lift Station

The Southern Trace Lift Station Improvements Project requires the contractor to make necessary repairs to the existing lift station. The work includes removal and replacement of existing piping and valves, bypass tee, concrete pavement, bypass pumping, wet well cleaning and grout patching, rebuilding existing self priming pumps, painting and miscellaneous needs.

Lift Station Improvements

Existing Lift Stations are on temporary bypass due to maintenance issues, and are not performing as needed to properly pump wastewater. The following lift stations are included in the project scope: Augurs, Cherokee, Forbing Glen, Glen Avenue, Lakeside Boat, Long Timbers, Pinecrest, Spring Lake, Woolworth Road, Land O’ Trees, and Maywood.

Amiss Water Treatment Plant Ozone Improvements

Modifications to the three existing treatment plants and processes. Work will include modifications to the Ozone Equipment and Chemical Filter Equipment, and Chemical Feed Systems along with installation of High Service Pumps and CO2 System as well as miscellaneous structural work throughout the plant.

Golf Links Boulevard Sewer Improvement Project

 The Golf Links Boulevard Sewer Improvements Project will require the
abandonment of 866 feet of existing 8 inch sewer main with flowable fill and 1 sewer manhole, and the installation of 838 feet of new 8 inch PVC sewer main and 2 sewer manholes. The proposed work will include clearing and grubbing, reestablishing 11 service laterals, installing 3
stainless steel manhole inflow preventers, concrete pavement replacement, bypass pumping, abandoning of the existing sewer main and manhole, and all other incidentals for temporary erosion and sediment control.

Cedar Creek Lift Station

The Cedar Creek Lift Station Project consists of the furnishing of all labor, materials, equipment, and incidents required for the rehabilitation of the Cedar Creek Lift Station.

City Wide Sewer Repair

The City Wide Sewer Repair contract has significantly enhanced the City’s ability to address emergency issues in a timely and efficient manner. Over 200 work orders have been completed to-date at a total cost of over $5 million. The City is considering expanding the
capacity of the current contract and implementing additional contracts to expand its ability to respond to emergency issues.

Edwards Sewer Improvement

Existing 6″ and 10″ gravity sewer mains have numerous defects contributing to a recurring SSO in the alley between Edwards and Milam.

Caddo Bossier Port Sewer Repair

The Caddo Bossier Port Sewer Repair Project includes repair of gravity sewer main that caused a sinkhole under existing Caddo Bossier Fuel Facility.

Manhole Rehabilitation and I/I Reduction

The Manhole Rehabilitation and I/I Reduction Project includes rehabilitation of manholes to address structural condition and infiltration and inflow (I/I) issues.

Feasibility & Development

During the Feasibility and Development Stage, the City uses various methods to inspect and analyze its system. Physical inspection is performed using cameras and other technologies. Data analysis is completed using engineering tools and processes. Master plans, hydraulic modeling, planning, assessments, and detailed engineering studies are often completed during this Stage. Based on an in-depth understanding of the system, the City can identify which areas are most in need of improvement. This allows projects to be prioritized, selected, and planned for capital expenditures. Design alternatives and concepts are often defined and selected during this Stage. This phase can take several months to several years depending on the complexity of the assessment.

After projects have been selected, engineering consultants are typically selected to develop designs for the projects. Securing engineering services, which includes defining the detailed scope of work, negotiating cost, preparing the required forms, contract and legal review, and City approval, typically takes between four and eight months.

Design

During the Design Stage, the engineer (either City staff or a contractor) prepares detailed plans and specifications for the project. Any needed servitude (easement) plats and permit applications are also prepared by the engineer. Completing detailed design documents for a typical project usually takes between 9 and 18 months. A complex design, permit approvals, or land (servitude/easement) acquisitions can extend the time required to complete this Stage.

Bid & Award

During the Bid and Award Stage, the City solicits proposals from bidders to complete construction of the project. Bids are advertised, received, and evaluated. Contracts are then executed with the selected bidder. This process typically takes 3 to 6 months to complete. 

Construction

Construction is when elements of the project are physically completed. The selected contractor is responsible for completing the project in accordance with the contract documents. The City and its consultants oversee, inspect, and document the contractor’s activities. Equipment installed during the project is commissioned to validate it is operating properly. Construction typically takes 6 months to 30 months to complete depending on the size and complexity of the project.

Post-Construction

During the Post-Construction Stage, the City operates and maintains the system. The City may also perform inspections of completed work during the correction period (warranty). Maintenance includes routine inspections, cleaning, and emergency repairs and replacements.
