Description/Scope of Work
The solicitation will be for a Indefinite Quantity Indefinite Delivery contract and it will be advertised as a Full and Open Competition Request for Proposal (RFP) in the $15M - $18M range (total ceiling). The expected total ordering of all task orders is in the $5M - $7M range. The work includes industrial cleaning of Clearwells, solids handling and disposal services at multiple locations in Washington, DC, NW. Specific work items include power washing the interior of concrete water storage tanks, collection, dewatering, and disposal of lime sediments, chemical application for disinfection and dechlorination of water, and the furnishing and operation of pumps and temporary generators.
The Washington Aqueduct provides potable water to approximately one million people in the District of Columbia and Northern Virginia. As part of the water treatment and supply system, the Washington Aqueduct maintains seven (07) underground storage tanks at its Water Treatment Plants and at various pressure zones within the city. The tanks are important components of the water supply system. The intent is to clean 2-3 of these tanks per year, though due to unforeseen circumstances we may clean more or less than that number, and may clean any tank at any time. The scheduling of service outages to accommodate the cleaning may be on short notice, and the duration of such outages constrained. Hence, an experienced contractor with resources and expertise to handle the following project constraints is needed:
i. The capacity of the reservoirs to be cleaned, are between 15 million gallons and 30 million gallons, with anticipated settled solids volumes of 100-1000 in-place cubic yards. The average out of service duration for
completion of the cleaning work is 8 weeks.
ii. The reservoirs are underground concrete structure with limited access, and some are equipped with baffling walls. The Contractor is responsible for all lighting, ventilation, and confined space entry procedures.
iii. The reservoir may or may not have gravity drains, and should be presumed to contain some volume of residual water due to sloping and contours of the floor and leakage through isolation gates. The Contractor shall be responsible for pumping to remove any remaining water to allow for the cleaning.
iv. The reservoirs are used to store treated and potable water so all materials used therein shall be NSF 61 approved. No equipment that uses hydraulic oil or other contaminant can be used in the reservoir.
v. The reservoirs are subsurface structures some of which are located in residential neighborhoods where there is limited space for storage and staging outside of the reservoir. Access openings into these reservoirs limited and the live load that can be placed on each reservoir roof slab is limited.
