Responsibilities

Develop and maintain P&IDs (Piping & Instrumentation Diagrams) in accordance with ISA 5.1 standards for all SCADA-integrated process areas including primary, secondary, and tertiary treatment.
Produce electrical one-line diagrams, panel layouts, and conduit/cable routing drawings for SCADA panels, field instrumentation, and communication infrastructure.
Create and update instrument loop drawings, junction box schedules, and field device location plans.
Draft control room layout drawings, operator workstation configurations, and server room/network room equipment arrangements.
Manage and maintain the drawing register and CAD standards in compliance with NYC DEP BWT documentation requirements.
Perform drawing markups, revision control, and as-built updates throughout construction and commissioning phases.
Coordinate with civil/structural, mechanical, and electrical engineering teams to integrate CAD deliverables into overall project drawing sets.
Develop detailed SCADA network architecture diagrams including OT/IT network topology, firewall zones, DMZ layouts, and communication pathways using Microsoft Visio.
Create HMI screen layout wireframes and navigation flow diagrams to support SCADA system design and client review sessions.
Produce functional block diagrams for PLC/RTU I/O, control loops, and inter-system communications (OPC-UA, DNP3, Modbus, Ethernet/IP).
Develop system integration diagrams showing interfaces between SCADA, historian, MES, asset management, and laboratory information systems.
Maintain and update Visio deliverables through all project phases from Preliminary Design through Commissioning and Closeout.
