Attachment 1, 12639525R0014 TITLE: Upgrade/Replace Lift Station and Sump Pit Pumping Systems

LOCATION: U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS), Plant Protection Quarantine (PPQ), National Center for Applied Plant Protection (NCAPP), 9901 Powder Mill Rd, Laurel, MD 20708.

PROJECT BACKGROUND: The NCAPP opened in 1979 to safeguard agricultural resources from the risks associated with the entry, establishment or spread of exotic plant diseases from foreign germplasm introduced into the United States. Over the years, expansion projects have added other Programs to the facility.

The 128,000 square foot facility is comprised of 10 connected buildings on 127 acres of property situated in a mostly wooded area. The campus includes greenhouses, screenhouses, offices, labs, and warehouse space.

Due to the multiple maintenance issues, antiquated equipment, and operational criticality for the facility, the current lift station pump system and downstream sump pump systems are obsolete and need replacing. The current system uses six Zoeller Model G294-E pumps—two pumps in three locations— installed in lead/lag configurations for redundancy. Several key components on the system are either deteriorating or inoperable, including deteriorating guide rails and supports needed for repair and/or replacement of the pumps. The effluent discharge piping has been reworked several times due to clogging with silt and other materials and is undersized for its application, resulting in numerous clogs requiring labor-intensive maintenance. Additionally, the discharge piping is not supported properly and routed improperly to facilitate proper function. The piping also blocks access to the adjacent pump control panels, creating an additional hazard for personnel maintaining the system.

The effluent lift station collection and pump system is connected to the Secret Service, then the USDA BARC sanitary sewer collection system. Currently, the facility transfers 3,000 plus gallons/day of liquid slurry/material. Operational and control voltages are 480 volts and 120 volts, respectively.

PROJECT DESCRIPTION: The purpose of this Statement of Work (SOW) is to procure construction services to install three new silt and solid handling pump systems within the lift station and downstream sump pump systems, including all required guiderails, supports, controls, valves, and piping modifications. The pumping systems shall be fully automated, high efficiency, and equipped with redundant features. These features will ensure the system is effective and lead to consistent results without making the process cumbersome or inconvenient. Contractor shall connect the new pump systems to the existing site/building infrastructure and computer system. Likewise, the pumps shall be a “stock unit” for ease of acquiring service and repair.

Project Phasing: Provide a phasing plan or implementation plan for approval by the AFM or authorized representative prior to proceeding, inclusive of processes/procedures to maintain pumping of waste during the construction phase.

Provide a Safety Plan and Quality Assurance/Quality Control (QA/QC) Plan for Government review and acceptance. QA/QC plan should address how project phasing is implemented to minimize impact to facility operations and preventative measures to mitigate fugitive dust, noise pollution and cross contamination during demolition and construction. Safety plan should address control of hazardous energies and confined space work practices.

Develop a Waste Management Plan: Plan should address where and how construction and hazardous wastes are diverted. Include estimated percentages for salvage, recycle, landfill, etc. Maintain records of disposal for submission to the Government at project closeout.

Facility will remain fully operational during the construction period. Coordinate construction with the AFM to minimize conflicts and downtime.

Remove and dispose of the existing pump systems, including all appurtenances, complete at coordinated low flow periods, up to and including off-hours work.
