[Hiring] BMS Estimator @Hunt St

Role Description

This is a hands-on BMS Estimator role for an experienced Building Management Systems and HVAC controls professional who can turn complex project documentation into accurate, commercially sound estimates. You’ll review mechanical, electrical and BMS drawings, specifications and equipment schedules, interpret control strategies and sequences, develop points schedules and controller selections, and assess BMS networks, field devices and third-party integrations including BACnet and Modbus.

Working closely with the estimating, engineering and project delivery teams, you’ll build detailed tender submissions covering materials, labour, engineering, commissioning and project management. You’ll also identify scope gaps, risks, exclusions and qualifications, review supplier quotations and prepare clear handover documentation for the Australian project team. Strong knowledge of HVAC plant and BMS architecture is essential, while experience with Reliable Controls and BidTracer or similar estimating software will be highly regarded.

Key Responsibilities

• Review mechanical, electrical and BMS drawings, specifications and equipment schedules.
• Interpret mechanical plant, HVAC systems and control requirements.
• Develop detailed BMS points schedules and controller selections.
• Estimate BMS network architecture, including BACnet/IP and BACnet MS/TP.
• Identify requirements for sensors, actuators, valves, dampers, VSDs, meters and other field devices.
• Identify third-party interfaces and integration requirements, including BACnet, Modbus and other common protocols.
• Interpret control strategies, sequences of operation and functional descriptions.
• Prepare detailed allowances for materials, labour, engineering, commissioning and project management.
• Review switchboard/MSSB requirements and BMS electrical interfaces.
• Obtain, assess and compare supplier quotations.
• Identify scope gaps, exclusions, qualifications, assumptions and project risks.
• Prepare detailed tender breakdowns and supporting documentation.
• Prepare clear handover documentation for the Australian project team.
• Work collaboratively with estimating, engineering and project delivery teams throughout the tender process.
