Report
Summary
This project is to equip Well 301 to put it into service to provide water during times of long-term water shortages, emergency outages, and during peak demand times. The well will provide water to customers located in the northwest part of the City. The production capacity is about 1,200 gallons per minute (gpm). The groundwater in this area contains arsenic and therefore a well-head treatment system is required. The scope of work for this project includes sizing of the well pump, installation of piping from the existing distribution system to the new well, an arsenic treatment system, and instrumentation and connections to the Water Services Department's Supervisory Control and Data Acquisition (SCADA) system.
MGC Contractors, Inc., will be responsible for means and methods relating to construction of the project, participating with the City in the local and Small Business Enterprise (SBE) goal-setting process and implementing the SBE process. MGC Contractors, Inc., will be required to solicit bids from prequalified subcontractors to perform work under the City's subcontractor selection process. MGC Contractors, Inc., may also compete to self-perform limited amounts of work for this project. MGC Contractors, Inc., will assume the risk of delivering the project through a GMP.
