Design of Lift Station #60 Rehab & Upgrade

<p>The Central Florida Tourism Oversight District (“District”) is seeking professional engineering services to design and develop plans and technical specifications for the rehabilitation and upgrade of Lift Station #60 (LS-60) located on the western side of Disney's Animal Kingdom adjacent to a stormwater pond.</p><p>The general scope includes addition of a permanent, independently powered surface-mounted backup pump capable of pumping full design flow, removal of the existing backup generator, along with full rehabilitation to all electrical and mechanical components. Including, but not limited to:</p><p>A. Preliminary engineering report, comprehensive design, permitting, and construction services.<br>B. Design a bypass pumping system to maintain continuous station operations during rehabilitation activities.<br>C. Assess and replace electrical control panel with alternative for adding conditioned electrical structure onsite.<br>D. Assess the need and placement of conditioning pumps (including but not limited to grinder/chopper, flush pumps, etc.) one for each of the two cells, and a mixer pump in the common influent channel.<br>E. Assess condition of influent gravity main (30”) and provide recommendation if lining is needed.<br>F. Install pump soft starters.<br>G. Install fall protection devices.<br>H. Install new diesel-powered emergency pump, controls, and piping and the removal of existing generator and controls.<br>I. Provide condition assessment and recommended repair and replacements for the above-ground crane system existing onsite.<br>J. Provide condition and performance assessment of all four (4) pumps.<br>a. Analyze current performance and runtimes versus original design points.<br>b. Provide recommendations for purchasing replacements or stock spares.<br>K. Replace lift station risers and bases.<br>L. Recoat wet well (two compartments totaling 21’) and upstream manhole.<br>M. Replace inoperable wet well isolation gates to restore intended use.<br>N. Replace existing isolation valves and discharge piping with an above-grade assembly to eliminate confined space entry requirements in the vault.<br>O. Replace various controls and appurtenances including floats, flow meter, wet well liquid level measurement device, air release valves, etc.<br>P. Replace and/or modify the supervisory control and data acquisition (SCADA) equipment.<br>Q. SCADA and controls coding shall support 24/7 monitoring of station operations, with real-time data communicated to the RCES control room using existing onsite radio and fiber systems.</p>
