Report
Summary
This project is to equip Well 301 to put it into service so that it can 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). Groundwater in this area contains arsenic and therefore a well-head treatment system is required. Design services will include design and sizing of the well pump, design of the 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 begin in an agency support role for the design phase service and then hold the construction contract with the City for construction of the project. Services rendered during the CMAR design phase include providing detailed cost estimating and knowledge of marketplace conditions; project planning and scheduling; construction phasing and scheduling that will minimize interruption to the City; alternate systems evaluation and constructability studies; advise the City on ways to gain efficiencies in project delivery; long-lead procurement studies and initiate procurement of long-lead items; assist in the permitting processes; protect the owner’s sensitivity to quality, safety, and environmental factors; and advise City on choosing green building materials.
