BMS Estimator

At Hunt St, we help Australian companies hire top remote talent in the Philippines. For this role, you will be engaged directly by the client as an independent contractor. We are not an outsourcing agency. All of our roles are 100% remote so you'll be able to work from home.

The client specializes in building automation, energy management, and optimization, helping clients reduce operating costs, improve building performance, and create better environments for occupants. They combine technology, engineering expertise, and practical experience to deliver solutions that are measurable, reliable, and built for the long term.

Role Overview: 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.
• Collaborate with estimating, engineering, and project delivery teams throughout the tender process.

Systems & Technical Scope: You should be comfortable estimating BMS and HVAC control systems involving:

• AHUs, FCUs, VAVs, and ventilation systems
• Chilled water and heating hot water systems
• Chillers, boilers, and heat pumps
• Cooling towers and condenser water systems
• VRF/VRV systems
• Pumps, VSDs, valves, and dampers
• Metering and energy monitoring systems
• BMS controllers, I/O, and field devices
• BACnet and Modbus integration
• BMS networks and supervisory systems

Requirements:

• Proven experience in BMS estimating, BMS engineering, controls engineering, or a closely related role.
• Strong knowledge of HVAC systems, mechanical plant, and building controls.
• Ability to interpret mechanical, electrical, and BMS drawings and specifications.
• Strong understanding of BMS architecture, controllers, I/O, and networks.
• Working knowledge of BACnet, Modbus, and third-party system integrations.
• Ability to understand sequences of operation and functional descriptions.
• Strong commercial awareness and attention to detail.
• Experience preparing detailed tenders, quotations, or project estimates.
• Ability to identify scope gaps, risks, exclusions, and assumptions.
• Strong written and verbal communication skills.
• Ability to work collaboratively with Australian-based estimating, engineering, and project teams.

Desirable:

• Experience with Reliable Controls — highly regarded but not essential.
• Experience with BidTracer or similar estimating/tender management software.
• Experience estimating BMS projects within the Australian commercial building environment.
