PROPOSALS are invited for the items and scope of work as follows: Water Treatment Plant Electrical: - Connection of two existing 2MW diesel electric generators, automatic transfer switches, paralleling controls, and appurtenances. - Refurbishment and upgrades to existing switchgear. - Construction of concrete foundation for the utility transformers. Constructionof a shade roof over electrical equipment. Dies Booster Station Electrical: - Installation of a 1200A automatic transfer switch and generator docking station at Building 2. 1075 Standpipe Electrical: - Demolition of existing solar photovoltaic panels, batteries, and charge controllers. - Provision of new solar photovoltaic panels, batteries, charge controllers, and enclosures. SCADA System: - Replacement of existing Wonderware HMI with Inductive Automation Ignition HMI at the Water Treatment Plant and the Dies Booster Station. - Upgrade and augmentation of PLC and RTU equipment throughout the water distribution system. - Replacement of radio communications and networking equipment. - Installation of underground fiber communications in select locations. The deadline to ask questions is 12/12/2022 5:00 PM CST The City's estimated total construction budget for this project is $2,336,000 Water Treatment Plant Electrical: The City of Cedar Park has pre purchased two, 2MW, 480V, diesel electric generators and associated transfer switches, paralleling controls, and switchgear modifications. This equipment and services are provided by LJ Power under Buy-Board #657-21, LJ Power Quote Number 220911- 011-DL. Additionally, LJ Power is providing early construction services for the generator foundation, runway, and partial duct bank construction including transportation and rigging of the generators. This scope of work is referenced under Buy-Board #657-21, LJ Power Quote Number 22111-004-DL. The contractor is responsible for providing the balance of materials and labor for completion of the electrical installation as described in the contract documents. This includes extension of the duct banks, concrete foundations for electrical equipment, construction of a shade roof over the new equipment, stairs, platforms, lighting, conductors, conduits, electrical testing, demolition of existing electrical service, relocation of electrical services, and fabrication of utility transformer platforms. Contractor will be responsible for coordination of installation activities with Pedernales Electric Cooperative (PEC), LJ Power, and the City to meet the installation sequence and schedule requirements. Dies Booster Station Electrical: The city of Cedar Park will pre purchase one 1200A, 3P, automatic transfer switch and one 1200A generator docking station for installation. This will be provided by LJ Power under Buy-Board #657-21, LJ Power Quote Number 220911-010-DL. The contractor will be responsible for installation of the transfer switch and docking station including a housekeeping pad, extension of existing conduits, conductors, and provision of a temporary generator for continuance of power in Building 2 during scheduled electrical outages. 1075 Standpipe Electrical: Utility electrical service is not available at the standpipe and all power is provided by solar photovoltaic panels and battery systems. The existing systems will be demolished and replaced. There are presently three separate systems, one for Cedar Park traffic control, one for Cedar Park SCADA, and one for Brushy Creek Regional Utility Authority (BCRUA) SCADA. These will all be removed and communication equipment consolidated into a single enclosure with solar photovoltaic panels, charge controller, batteries, voltage converters, and provisions for external, emergency generator power. Existing antenna feedlines and instrumentation cables will be extended to the new enclosure via conduit and junction boxes. This site is accessible only by unimproved roads. SCADA System: The City of Cedar Park is presently using Wonderware for their SCADA HMI. There are two core installations, one at the Water Treatment Plant, and one at the Dies Booster Station. These software installations will be replaced with Ignition by Inductive Automation. SCADA communication is presently realized with a mixture of unlicensed serial and Ethernet radios. All radios will be replaced with new unlicensed Ethernet radios, network switches, routers, and cellular modems form a redundant, fault tolerant network. Existing PLC's at most of the City's water sites are Siemens LC3000. These will be replaced with a mixture of Schneider M580 and M340 components. Sites with less extensive I/O and control requirements will be upgraded with Opto 22 Groov Rio units. New Ignition servers, workstations, historians, MQTT Brokers, network attached storage, and equipment racks will be provided at the Water Treatment Plant and at Public Works. The contractor will provide equipment, installation, and testing services. All development and programming services for Ignition, communications equipment, OIT screen development, and PLC programming will be provided by McKim & Creed. The contractor will include the fixed price line item in their proposal for McKim & Creed programming services as shown in the bid tabulation.
