Chen Moore and Associates' utilities engineering services include providing stormwater master planning and design, water and wastewater treatment, transmission, collection and distribution systems design. Some sample projects are highlighted below.
Pompano Beach Lift Station Rehabilitation Program
Chen Moore and Associates is responsible for managing the planning and design of the city's Lift Station Rehabilitation Program. The previous lift station improvement projects for the city of Pompano Beach include the following:
LS 2, 3, 4, 11, 24, 102, 110 & 44 Rehab or Replacement.
Chen Moore and Associates is the prime consultant responsible for the design, permitting, and construction administration for the rehabilitation of these existing lift stations. These rehabilitation/replacement projects include the construction of new force mains which will connect each lift station into the sanitary pressure network for the city of Pompano Beach, upgrading and replacing the existing pump and control panel components as necessary, as well as verifying whether the existing generator will continue to operate under the proposed pumps. Under the Lift Station 24 contract, Chen Moore and Associates also developed a computer model of the city's force main network using the SewerCAD software to allow analysis of the pressures within the network.
Lift Station 21- Chen Moore and Associates was responsible for the design, permitting and construction administration for the relocation of the existing LS 21 (master pump station) serving a majority of the city's barrier island. After completing the Basis of Design Report, Chen Moore and Associates proposed a variety of options to handle the approximately 3,500 GPM (Gallons Per Minute) existing flow and conducted follow-up odor studies for specific design purposes. The design options included in-line booster and submersible pumps with variable frequency drives and liquid and vapor phase treatments. Additional concerns included odor control, dewatering contamination and electrical supply and generation. The final design involved a submersible lift station coupled with biological vapor phase odor control and strategic chemical liquid phase odor control.
Turnpike 48" Forcemain Replacement
Chen Moore and Associates was the prime consultant of a design-build team tasked to design, permit and construct the relocation of a 48-inch force main in the Florida Turnpike Right-of-Way (ROW). This project involved the open cut installation of approximately 5,400 LF (Linear Feet) of 48" DIP (Ductile Iron Pipe) followed by the removal of the existing PCCP (Prestressed Concrete Cylinder Pipe). Coordination activities included Florida's Turnpike Enterprise of the Florida Department of Transportation (FDOT), South Florida Water Management District, the Florida Department of Environmental Protection and Broward County Water and Wastewater Services. The project schedule was an aggressive 112 days from Notice to Proceed to completion.
This project involved extensive permitting and coordination with the FDOT Turnpike as the entirety of the pipeline project fell with the Turnpike's Limited Access ROW. MOT (Maintenance of Traffic) and utility plans were permitted through the turnpike including staging areas for pipe stringing and lay-down yards. Additionally, extensive coordination with the Turnpike Construction Office was required as this project immediately proceeded a turnpike widening project and several restoration efforts were as-built and communicated. Finally, coordination with the turnpike environmental coordinator and their subconsultant Handex was required as the dewatering permitting operations discovered contamination at the FDOT Rest Area adjacent to the project site and monitoring was required throughout the dewatering operations.
Broward County Aviation Department Stormwater Master Plan
Under Phase 1 of this project, the Broward County Aviation Department (BCAD) retained Chen Moore and Associates to update the Fort Lauderdale/Hollywood Stormwater Master Plan (SWMP), which was completed by a previous consultant in 2001. CMA reviewed the data and analysis from all prior reports, converted the existing stormwater model from Stormwater Management Model (SWMM) to ICPR, and updated the ICPR model with any new system data and new projects provided by BCAD. Chen Moore and Associates updated the existing conditions stormwater model and created the future conditions stormwater model to assess alternative drainage improvements needed to achieve required and desired Levels of Service (LOS) for various storm events. The stormwater model was used to run rainfall scenarios for the comparison of pre-development (existing) conditions versus post-development (future) conditions from a water quantity (runoff) and water quality (storage) perspective. The stormwater model was used to analyze the performance of the existing Primary Stormwater Management System (PSMS).
The purpose of Phase 2 is to provide routine updates to the stormwater model(s) based on progress design drawings of the South Runway Expansion Project and the associated future development, including but not limited to, terminal and gate area improvements. The existing stormwater model created during Phase 1 includes design assumptions based on preliminary planning documents for the South Runway Expansion Project. The updates to the stormwater model during Phase 2 will be based on progress design submittals for the South Runway Expansion Project and approved design plans for other new development at Fort Lauderdale, which will enhance the accuracy of the stormwater model.
Miami Beach – Southpointe Phase III/IV/V ROW Improvement Project
Chen Moore and Associates is the prime consultant responsible for providing surveying, planning, geotechnical investigation, design, permitting, preparation of construction documents, bid and award and construction engineering and inspection services for infrastructure improvements within the public right of way areas of the South Pointe III/IV/V neighborhood of Miami Beach. The project encompasses approximately 19,000 LF of ROW infrastructure improvements including water main replacements, stormwater drainage improvements, paving & grading, streetscaping enhancements, landscaping improvements, lighting improvements, and roadway reconstruction.
Due to the existing mixed residential and commercial environment of this neighborhood, special design efforts were made to incorporate walkable community elements including meeting all ADA requirements, providing street furniture, providing bicycle paths, upgrading sidewalks, incorporating specialty treatments at crosswalks, landscaping improvements with specialized tree wells to provide a walkable surface and bulb outs to increase pedestrian friendliness and safety. This project requires extensive coordination with the public, adjacent community redevelopment associations, historic districts and various regulatory agencies in the form of community design workshops and special outreach meetings to individual special interest groups.
Cudjoe Regional WW Collection Project
Chen Moore and Associates is the engineering consultant for the final design and permitting of installation of wastewater collection systems within Monroe County. Recognizing that the economic health of Monroe County and its municipalities relies largely on the environmental health of a unique marine ecosystem, the county's Year 2010 Comprehensive Plan mandated that nutrient loading levels be reduced in the marine ecosystem of the Florida Keys. In June of 2000, the Sanitary Wastewater Master Plan (Master Plan) was finalized with the goal of eliminating approximately 23,000 private on-site wastewater systems by July 2010. Through interlocal agreement, Monroe County has requested that the Florida Keys Aqueduct Authority (FKAA) design, build, and operate county-owned infrastructure on behalf of the citizens in the master-plan prescribed service areas.
The service areas for the proposed wastewater collection systems under this project include Big Pine Key, Little Torch Key, Ramrod Key, Noname Key and Lower Sugarloaf Keys. Chen Moore and Associates is responsible for the final planning, design and permitting services to cover the non-central service areas of the regional system. The final product will be a permitted conveyance system that will combine various wastewater collection system technologies in order to connect as many on-site wastewater systems as possible for the lowest overall cost. The combined strategic utilization of proper planning and technology, extending to the greatest number of connections for the best value, is an approach developed by the FKAA through its years of experience in the water and wastewater utility business.
