You're right, SCADA integration definitely falls into the realm of "computer stuff," but it's specialized "computer stuff" that requires specific expertise. Here's a breakdown of the types of companies that work with, modify, and install SCADA systems

1. SCADA System Integrators:
What they do

These are the primary companies you'll encounter. They specialize in the design, implementation, configuration, and maintenance of SCADA systems. They act as the bridge between your physical processes (like water treatment, pipelines, manufacturing) and the software that controls and monitors them.

Key skills

Understanding of industrial control systems (ICS), PLCs (Programmable Logic Controllers), HMIs (Human-Machine Interfaces), communication protocols (Modbus, DNP3, OPC), database management, networking, cybersecurity, and specific SCADA software platforms.

Who they work for

End-users (like the companies operating the plants/facilities using SCADA), OEMs (Original Equipment Manufacturers) who build SCADA systems, and engineering firms involved in large infrastructure projects.

Example Services

SCADA system design & architecture PLC programming HMI development Communication network setup (wired and wireless) Data acquisition and logging Alarm management Reporting and analytics Cybersecurity hardening Integration with existing systems (like ERP, CMMS, other databases) Training Maintenance and support

2. Automation Companies/Industrial Automation Specialists



What they do

These companies provide a broader range of automation solutions, including SCADA, but also encompassing robotics, process control, and other automation technologies.

Key skills

Similar to SCADA system integrators, but with a wider breadth of knowledge across different automation disciplines.

Relationship to SCADA

They might handle the overall automation project, with SCADA being a key component. Or, they might subcontract the SCADA portion to a specialist.

3. PLC (Programmable Logic Controller) Specialists/Vendors



What they do

PLCs are the "brains" of many SCADA systems. These companies specialize in programming, installing, and maintaining PLCs.

Relationship to SCADA

While they don't directly build the entire SCADA system, they are crucial because they program the PLCs that interface with the sensors and actuators in the field and communicate with the SCADA server. The PLCs bring the data and execute commands in the field.

4. HMI (Human-Machine Interface) Developers



What they do

HMIs are the graphical interfaces that operators use to interact with the SCADA system. These companies specialize in designing and developing intuitive and effective HMIs.

Relationship to SCADA

HMI development is a critical part of SCADA, ensuring operators can easily understand the status of the system and control it effectively.

5. Network and Cybersecurity Specialists



What they do

SCADA systems rely heavily on networks for communication. These companies specialize in designing, implementing, and securing industrial networks. Cybersecurity is a huge concern in SCADA, as these systems are critical infrastructure and potential targets for attacks.

Relationship to SCADA

They ensure the SCADA network is reliable, secure, and meets the performance requirements of the application.

6. SCADA Software Vendors



What they do

These companies develop and sell the SCADA software platforms themselves (e.g., Wonderware, Ignition, Siemens WinCC).

Relationship to SCADA

System integrators will typically work with one or more SCADA software platforms, and often have certifications or partnerships with these vendors. Vendors might also offer training and support to integrators.

7. Engineering Firms (E&C Companies)



What they do

Engineering, Procurement, and Construction companies that oversee large infrastructure projects.

Relationship to SCADA

They may subcontract SCADA integration to specialist firms. They will often be the project managers and hold overall responsibility for the project.

How This Relates to Your Bidding



Subcontracting

The easiest option for you is to subcontract the SCADA portion to a qualified system integrator. Get quotes from a few different integrators before bidding. Include their quote as a line item in your bid.

Partnerships

If you frequently encounter SCADA requirements, consider forming a partnership with a reliable SCADA integrator.

Scope Clarification

In your bid, clearly define the scope of work you are responsible for and explicitly state that SCADA integration is a separate line item. This protects you from being held responsible for tasks you're not qualified to perform.

Due Diligence

If you're asked about SCADA, even if you're subcontracting, it's helpful to have a basic understanding of what it is and who you're planning to use. This shows the client you're taking the project seriously.

Example of a Better Response:

Instead of "Dunno, looks like computer stuff to me," try something like:"SCADA integration is a specialized area involving industrial control systems and software. I typically partner with a qualified SCADA system integrator for this portion of the work. I can get a quote from one of my trusted partners and include that as a separate line item in the bid, or, if you have a preferred integrator, I'm happy to work with them."By acknowledging the expertise required and explaining your approach to handling it, you'll build confidence with the client.Good luck with your bidding!
