Design, Build, and Engineering

GDI Ainsworth’s multi-disciplined engineers take a cutting-edge approach to design, build, installation, and upgrades. Our team’s broad base of knowledge and advanced technology allows us to offer exceptional services to handle engineering challenges.
No matter the scope and budget of your design-build project, our technicians have the expertise and resources to help accomplish your goals.

Build Better From Concept to Completion

In design-build, the risk is in the hand-offs. You need a partner who can engineer for performance, coordinate trades without friction, and hit schedule and budget without compromising safety or compliance.
GDI Ainsworth brings licensed engineering, a CSA-certified panel shop, BIM-driven coordination, and 24/7 national operations support under one roof. We design, fabricate, install, commission, and hand you a building that performs on day one and keeps performing year after year.

Engineered for Performance, Safety, and Compliance

Every decision starts with outcomes: comfort, reliability, energy, and code compliance. Our multi-discipline engineers design to stringent QA/QC standards and validate results throughout delivery.

  • BIM/VDC & digital coordination for clash-free routing, accurate quantities, and clean shop drawings.
  • Documented QA/QC—ITPs, FAT/SAT, and conformance records aligned to ISO 9001 quality management.
  • Regulatory alignment with local codes and industry guidance (e.g., ASHRAE, CSA, NEC/NFPA) and sector-specific protocols for healthcare, Life Sciences, food plant, and mission-critical spaces.
Engineered for Performance, Safety, and Compliance
Faster Delivery With Prefabrication and Digital Delivery

We move work offsite to control cost, quality, and schedule and then install with surgical precision onsite.

  • Prefabricated assemblies (riser systems, pump skids, duct sections, valve packages) are produced in controlled environments to reduce rework and onsite congestion.
  • CSA-certified panel fabrication for BAS and power/control, complete with labeling, testing, and documentation.
  • Model-to-manufacture workflows tie BIM directly to shop output for exact fit-up and repeatability across campuses.
  • Lean installation sequencing shortens critical paths and improves safety by minimizing field hours.
  • Digital turnover as-builts, O&M data, and asset registers delivered in open formats for your CMMS/BMS.
Faster Delivery With Prefabrication and Digital Delivery
Open, Future-Proof Building Automation

Lock-in kills flexibility and cost control. As a Master Systems Integrator, we design open building automation systems that you control long-term, not the other way around.

We standardize tagging, use open protocols (e.g., BACnet), and integrate with enterprise systems and occupant apps via REST APIs, so you can scale, swap, and upgrade on your terms.

Open, Future Proof Building Automation
One Program, Zero Hand-Offs

With GDI Ainsworth, your design-build can transition seamlessly into operations. Our Integrated Facility Services framework combines technical expertise, facility maintenance, and janitorial cleaning and disinfection programs under a single agreement. Backed by our 24/7 National Operations Centre, you get one agreement, one set of KPIs and a single accountable partner.

Our Specialized Services

HVAC Systems Designed for Comfort and Efficiency

Our experienced team has what it takes to design and build mechanical and HVAC systems. We’ll partner with you to take your next large-scale, industrial HVAC construction plan to the next level. 

We follow strict safety protocols to prevent onsite incidents and reduce the risk of airborne transmission, and we’ll guide you in selecting the right equipment for your facility. Whether it’s a new installation, an expansion, or a system replacement, we deliver HVAC solutions that keep your environment comfortable and efficient from day one.

Ready for installation, ready for value

GDI Ainsworth offers pre-fabrication solutions for our building automation controls and provides customized panel solutions for our clients’ facilities and campuses. Our dedicated and fully certified CSA panel shop can build turn-key solutions for clients across North America.

In fast-paced design-build projects, it’s critical to shorten build time, lower life cycle costs, and deliver consistent, factory-built quality on every job. From schematic design concepts through completion, we provide 100% customizable options for each individual application. Our modular solutions allow for every architectural component of the room or corridor to be pre-manufactured, while coordinating with mechanical and electrical service experts to provide completely seamless installations.

Plumbing Systems That Work, Period

Plumbing is one of the hidden systems that defines the daily experience in your facility. When it’s designed right, everything runs smoothly, but when it fails, costs and disruptions escalate fast.
GDI Ainsworth’s engineers design and integrate plumbing systems that are built to perform reliably from day one. By involving our team early in the design phase, you gain systems tailored to your building’s needs, reduce the risk of costly retrofits, and ensure long-term efficiency and occupant satisfaction.

The Perfect Environment for Your Specialized Needs

From production labs to museums to climate-controlled warehouses, specialized facilities demand absolute precision. Our teams design and build systems that protect your assets, research, and operations while staying on budget.
Once installation is complete, our service teams, trained in the exact technologies and parameters of your environment, provide the ongoing expertise needed to maintain performance and compliance long term.
Industries We Serve

Design, build and engineering services set the stage for how every facility performs over its lifetime. From healthcare facilities and industrial spaces to commercial offices and education campuses, we adapt our expertise to create environments that are efficient, compliant, and built to last.

Design, Build & Engineering FAQs

What makes GDI Ainsworth different from other design-build firms?

Unlike niche contractors, we integrate multiple disciplines under one accountable program. With ISO-certified processes, prefabrication capabilities, and a CSA-certified panel shop, you get predictable outcomes and fewer hand-offs.
No. While we have the resources and scale to manage major industrial and institutional projects across North America, we also deliver tailored solutions for smaller facilities that require the same level of precision and compliance.
We use BIM/VDC coordination, prefabrication, and Lean sequencing to eliminate rework and keep schedules tight. Paired with transparent reporting and 24/7 oversight from our National Operations Centre, clients have real-time visibility into cost and progress.
Yes. Our Integrated Facility Services framework allows us to extend support beyond commissioning—covering facility maintenance, cleaning and disinfection, and technical operations—under a single agreement and set of KPIs.
