Plant control
PLC programming for retrofit and modernization projects, with Siemens and Rockwell experience. We assess what can safely remain before specifying what needs to change.
Hot Mix Asphalt · PLC · HMI · SCADA · Cloud
Controls Engineering for the Hot Mix Asphalt Industry.
PLC, HMI, SCADA, database, and cloud services for hot mix asphalt plants. We help operators and plant owners scope, build, and refine plant control systems.
A boutique consultancy focused on hot mix asphalt plant automation.

Three areas of focus.
Scoped to the project. We're happy to say no if it isn't the right fit.
Operator HMI
HMI screens aligned with ISA-101 guidelines. Mix and recipe screens, totals, calibration, alarm banner. Designed with operators in mind.
Data & reporting
SQL Server historian and reporting. Optional cloud-based dashboard integration for KPIs like tons, fuel, and downtime, scoped to what's useful for your operation.
Why focus on asphalt
It's the industry we know.
Our principal's background includes time at Astec Industries and, since then, control system integration in the hot mix asphalt space for decades. Working in one industry means we can spend more time on the details that matter.
- P.Eng-led — Registered with Engineers and Geoscientists of British Columbia (EGBC)
- IEC 61131-3 conventions for PLC code structure
- ISA-101 guidelines applied to HMI design
- ISA-18.2 as a reference for alarm management
- Vendor experience with Siemens and Rockwell platforms

What's next
Exploring AI & ML for asphalt plant efficiency.
Alongside our delivery work, GA Engineering Inc. is a Canadian SME engaged in applied R&D. We're exploring how modern data tooling and machine-learning techniques can help hot mix asphalt plants run more efficiently — without taking the operator out of the loop.
- Burner control — data-driven setpoint suggestions to reduce fuel per ton even as the NOX emissions are minimized
- Mix recipe queue & planning — sequencing the day's jobs to cut mix-change losses and interfacing with client's logistics structure
- Maintenance signals — forecasts based on data already collected
Canadian SME · Applied R&D
Aligned with Canadian innovation.
We are actively exploring collaborative partnerships and strategic funding mechanisms to support applied industrial research within Canada, leveraging both federal and provincial innovation frameworks.
If you are a producer, OEM, researcher, or program officer focused on advancing industrial AI/ML applications within heavy industry, we would welcome the opportunity to connect and discuss potential synergies.
How an engagement typically goes
A simple, scoped approach.
An illustrative outline — every project is unique
From an initial conversation to a working system.
Our process begins with an in-depth consultation to understand your plant's operational challenges. When beneficial, we conduct an on-site technical assessment to map existing I/O, identify what can be responsibly reused, and document system requirements. We always deliver a detailed, written scope of work before any programming begins. To minimize operational disruptions, we strategically schedule deployments around your off-season windows, ensuring final cutovers land safely outside the busy paving schedule.
What we won't do is over-promise. If a project isn't a fit — for scope, schedule, or specialty — we'll say so and, where we can, point you to someone who's a better match.

Built to outlast the engagement.
Long-lived plant systems deserve long-lived support arrangements — and a backstop for when the unexpected happens.
Source-code escrow
Independent third-party escrow available on qualifying engagements. The deposit is verified by the agent, not just archived.
How it worksDocumented handover
Every project ends with the tag maps, drawings, and runbooks a competent controls team would need to keep the system running.
Long-term support
Support arrangements are scoped up front, not bolted on. We're honest about what a small team can and can't cover.
