Dalecarlia Backwash Tanks Improvements

This is a Pre-Solicitation Notice This project will be announced as W912DR19B0008. Project: Dalecarlia Backwash Tanks Improvements The proposed procurement is unrestricted, NAICS 237110 with a magnitude of construction between $1,000,000.00 and $5,000,000.00. The main focus of the project is to modify both the supply and waste backwash facilities to restore their infrastructure, improve reliability and address sanitary deficiencies. At the Dalecarlia WTP, there are two wash water storage tanks known as the Underground Tank and the Elevated Tank, respectively. Wash water is supplied to the wash water storage reservoirs through an altitude valve, located in the Dalecarlia Pumping Station, which simultaneously supplies water to each of the tanks through 24" and 30" cast iron water mains. Waste water from the backwash process is recycled to the Dalecarlia Forebay via a subsurface Backwash Recovery Pumping Station (BWPRS). The BWPRS operates two centrifugal pumps, which are critical to the Dalecarlia WTP environmental permitting compliance. Major features of the project consist of the construction of a drain outlet structure, the installation of a subsurface waterproofing membrane, the replacement of tank corrosion protection system, the installation of new electrical switchgears, variable speed drives, transfer switches, etc., the rehabilitation of altitude valves and the replacement of valves, actuators and actuator control systems. Hence, an experienced contractor with resources and expertise to handle the following project constraints is needed: i. The BWRPS shall remain operational and service disruptions shall be minimized. Therefore, the installation of the existing electrical equipment shall be performed in phases. ii. Active de-chlorination of leakage and backwash water will be required to handle all water that by-passes the BWRPS prior to discharge to the river. iii. Access into the backwash tanks is limited and all work therein is considered confined space work. iv. Programming work needed to tie process control systems into the SCADA system shall only be performed by contractors that have been security cleared. v. Access control for security to the site shall be maintained, to include security screening of personnel, control of access keys, and temporary fencing and locks as necessary. The solicitation will be provided in an electronic format, free of charge on or about 23 August 2019, to all authenticated account holders registered with the Federal Business Opportunities (FBO) System.
