A&P CONSULTING TRANSPORTATION ENGINEERS, CORP. GOLDEN SHORES PUMP STATION REHABILITATION (CCNA) RFQ 18-11-01 8 METHOD OF APPROACH TO THE PROJECT Rehabilitation of Existing Pump Station The goal of the APCTE Team is to provide a stormwater pump station that is both easily operated and maintained and consistent with the City’s quality standards. For this work, we have taken into consideration site and hydraulic constraints, and all key technical issues that apply to this particular pump station. Knowing that the hydraulic conditions define the flow and total dynamic head (TDH) conditions that will be required, if the decision is made to replace the pumps, then selecting the right pump will be critical. Noise levels will be measured to verify background noise during day and nighttime conditions. Acoustical features will be incorporated into the facility design to manage noise levels to the maximum extent possible. Another component of a successfully designed project is visually blending the infrastructure with the surrounding area. In a way this is more art than science, and involves the use of appropriate architectural and landscaping features to screen a facility from view and make it aesthetically pleasing. Equally important aspect is to consider maintenance and equipment removal. Our design approach to maintenance of equipment is to provide an adequate clearance between adjacent equipment, provide lifting capability for each piece of equipment that will need to be removed, establish a clear path to remove a given piece of equipment from the facility and provide easy access to frequent maintenance items such as lubrication points. Also, our team will recommend the City’s staff to establish a secure facility consistent with the City’s requirements. This can be accomplished by providing security cameras, fire detection and alarm systems. Lastly, we will take into consideration the effects of Sea Level Rise. The City of Sunny Isles Beach is considered one of the most vulnerable areas to climate change and especially susceptible to impacts such as rising sea levels. To mitigate these effects, we will design the mechanical and electrical components of this pump station taking into consideration the potential of sea level rise to ensure that this facility will function properly for the estimated design life of the project. The work to be performed includes site preparation, earthwork, storm drainage infrastructure cleaning and inspection, and refurbishing of the existing pump station. In addition to the construction related services, the project will require engineering design, permitting, surveying services, utility locations, landscape architecture, and potentially geotechnical services. The project needs to be substantially completed before the next rainy season. All required performance testing, training, installation certification, and acceptance by the City shall be performed prior to substantial completion. The storm water pump station design will follow federal, state and local laws to be in full compliance with the City’s RFQ, governmental ordinances and regulations. To prevent flooding, the lowest elevation of the control panels will be evaluated and reset 2 feet above of the base flood elevation (BFE). These panels will include an emergency generator receptacle of sufficient amperage to allow operation of the pump station in the event of a power failure, and in addition it will include adequate space and connections to warrant the installation and integration of future SCADA equipment to be installed by others. Prior to installation, our team will coordinate the integration of the SCADA system with the City of Sunny Isles. The control panels will be screened, and the areas surrounding the control equipment will be beautified with a suitable landscape buffer. The control panels will have an enclosure that is being currently being designed by the City and it is expected to be complete during construction. We will coordinate the enclosure completion and installation with the City. Our proposed design will include a new pump controller with local override capability. Normal pump station operation will be based on new transducer levels while float switches will be provided for back-up operation. We will propose a SCADA RTU enclosure, antenna and required devices to allow for remote monitoring and control of the pump station. RTU selection will be coordinated with the city to deliver real-time alarms via phone, text message, email, etc. Communication of the RTU with the SCADA computer system will be wireless via cellular radio unless the city has any copper or fiber optic network available in the area
