Orange County West Campus Office Building -HVAC PDC Project 23020 BAS DIRECT DIGITAL CONTROL SYSTEM 23 09 02 - 1 SECTION 23 09 02 BAS DIRECT DIGITAL CONTROL SYSTEM PART 1 GENERAL 1.01 WORK INCLUDED: A.Integrating equipment in the project scope into the existing Siemens Building Automation System (BAS),incorporating direct digital control (DDC)for energy management,equipment monitoring and control,and subsystems with open communications capabilities as herein specified. B.Furnish all labor,materials,equipment and service necessary for a complete and operating Building Automation System (BAS),utilizing Direct Digital Controls. C.The system will integrate and communicate to the existing BMS server (by Siemens)flawlessly so that all information and points can be viewed from the existing automation software and BMS server.The Owner shall be able to log onto the existing automation server and navigate to the controlled components being installed as part of this project.Information from other sites shall be able to be transmitted and shared in its entirety. D.The equipment installed under this project must be connected to the existing Siemens building automation server. E.The installation of the control system shall be performed under the direct supervision of the controls manufacturer representative with the shop drawings,flow diagrams,bill of materials, component designation or identification number and sequence of operation all bearing the name of the manufacturer.The installing contractor shall certify in writing,that the shop drawings have been prepared by the equipment manufacturer representative and that the equipment manufacturer representative has supervised their installation.In addition,the equipment manufacturer representative shall certify,in writing,that the shop drawings were prepared by their company and that all temperature control equipment was installed under their direct supervision. F.Provide system graphics for each controlled device and/or integrated systems as required by the Owner.Origin of information shall be transparent to the operator and shall be controlled,displayed, trended,etc.as if the points were hardwired to the BMS. 1.02 GENERAL PRODUCT DESCRIPTION A.All materials and equipment used shall be standard components,regularly manufactured for this and/or other systems and not custom designed especially for this project.All systems and components shall have been thoroughly tested and proven in actual use for at least two years. B.The system shall be scalable in nature and shall permit expansion of both capacity and functionality through the addition of sensors,actuators,DDC Controllers,and operator devices. C.System architectural design shall eliminate dependence upon any single device for alarm reporting and control execution.Each DDC Controller shall operate independently by performing its own specified control,alarm management,operator I/O,and data collection.The failure of any single component or network connection shall not interrupt the execution of any control strategy, reporting,alarming and trending function,or any function at any operator interface device. D.DDC Controllers shall be able to access any data from,or send control commands and alarm reports directly to,any other DDC Controller or combination of controllers on the network without dependence upon a central or intermediate processing device.DDC Controllers shall also be able to send alarm reports to multiple operator workstations without dependence upon a central or intermediate processing device. E.All DDC controllers shall be installed with 10%spare points (of each type)and 10%spare memory capacity for connection of floor work. 1.03 APPROVED CONTROL SYSTEM CONTRACTORS AND MANUFACTURERS A.The following are the approved Control System Contractors and Manufacturers: 1.Siemens Industry,Inc.,APOGEE System 1.04 QUALITY ASSURANCE Docusign Envelope ID: 8DED1454-68D2-4E36-9FC6-E56FF2124E5D
