Facilities EPCM for Energy Operators in Calgary & Houston

30+ years of full-service EPCM, Calgary and Houston. Achieving your small-to-medium infrastructure goals. Earning your trust.

No Project Too Small — Up to $100MM Facilities, $200MM Pipelines

Tundra’s fit-for-purpose EPCM approach works from the small MOC project up to the $100MM gas plant. We publish our project-size range so you know before you call whether you’re too small to matter — the answer is no.

Calgary and Houston, One Engineering Team

Projects on both sides of the border run through the same team, the same standards, and the same fit-for-purpose, client focused approach — no handoff to an unfamiliar partner firm when a client crosses the border.

Engineering Costs Published Before You Call

Our pricing page shows engineering as a percentage of total project cost — 3–4% for multi-pipeline programs, 9–10% for greenfield projects, and up to 13%+ for complex brownfield projects and turnarounds with minimal downtime. Budget your project before you’ve had a single meeting.

Every Discipline In-House — Process to PLC

Process, mechanical, electrical, automation (PLC, SCADA, RTU), laser-scan field verification, environmental and regulatory all sit under one roof. Nobody on your project is waiting on a subcontractor’s schedule.

Every Service, Grouped by Engineering Discipline

Every service Tundra Engineering offers, grouped by the discipline that owns it. Each entry links to the full service page. Most brownfield work should start with field data — laser scanning, field verification and a complete as-built drawing package — because you cannot design against drawings that no longer match the plant. Common questions about scope, schedule and cost are answered in They Ask, We Answer.

Engineering Consultant

Most projects go sideways in the space between disciplines — a change gets made in the field but never makes it back to the drawings, or a scope decision gets made without anyone owning the schedule. Tundra acts as EPCM contractor or owner’s engineer on projects from a single MOC up to a $100MM facility, carrying one accountable team from early definition through commissioning. The same team keeps the change records, documentation and production data honest long after startup.

• EPCM Project Delivery / Owner’s Engineer — Engineering, procurement and construction management under one accountable team, from early definition through commissioning.
• Management of Change (MOC) — Controlled evaluation and documentation of facility changes so modifications are engineered, approved and recorded rather than improvised.
• Complete As-Built Site Drawing Package — Field-verified drawing sets that replace outdated documentation with a record matching what is actually installed.
• Artificial Intelligence in Production Operations and Facilities — Applied AI for production data, giving operations teams earlier warning of performance and reliability problems.

Gas Engineer

Gas plants running below nameplate capacity, or tripping during winter peak demand, are usually a process or controls problem, not an equipment problem. Our Calgary-based gas engineering team designs and debottlenecks treating, compression, and dehydration systems so throughput matches what the reservoir can actually deliver. From new gas processing facilities to fixing an underperforming plant, we handle the full scope in-house.

• Gas Processing and Treating Plant Engineering — Design and expansion of gas plants, from single-stage recovery through sour processing with amine treating.
• Gas Refrigeration — Refrigeration and dewpoint control systems sized to the liquids recovery the reservoir can actually support.
• Fugitive Emissions Studies — Measurement-based leak detection and quantification programs built for regulatory reporting, not checklists.

Design Engineer

A design that looks complete on paper but stalls at construction usually means procurement and fabrication weren’t considered early enough. Tundra’s design engineers in Calgary and Houston build constructability and cost control into FEED and detailed design from day one, not after the first change order. That’s how small-to-medium capital projects stay on budget and on schedule.

• Wellsites and Multi-Well Pads — Surface facility design for single wells through multi-well pads, with layouts that suit how the site is operated.
• Suspended Well Programs — Engineering and documentation for suspension obligations carrying regulatory deadlines.
• Plant Debottlenecking — Finding the real constraint in an existing facility and removing it before anyone commits to new equipment.
• 3D Laser Scanning — Point-cloud capture of existing plants so design starts from measured reality instead of drawings that no longer match.

Chemical Engineering Service

Off-spec product, unplanned downtime, or a process that never quite hit design rates all trace back to the chemical and process engineering behind the facility. Our Calgary and Houston process engineers rework mass and heat balances and fix the root cause instead of the symptom. It’s the same rigor whether the project is a single skid or a full gas plant.

• Chemical and Process Engineering — Heat and material balances, equipment sizing, hydraulic and thermal checks and relief and flare verification that set what a facility can actually do.
• Plant HAZOPs — Facilitated hazard and operability reviews led by engineers who understand the process, not just the methodology.
• Process Reviews and Capacity Studies — Mass and heat balance work that answers how much more an existing facility can absorb before the next unit is needed.
• Hydrocarbon Gas Treating and Conditioning — Treating and conditioning systems that bring off-spec gas back to sales quality.
• Gas Sweetening — Amine and related sweetening systems for sour service, including H2S handling and sulphur management.

Hydraulic Engineer

Pipeline systems that lose pressure, cavitate, or can’t hit contracted delivery rates need hydraulic engineering, not just bigger pumps. We model pipeline and facility hydraulics across our Calgary and Houston projects to find the real bottleneck before anyone spends money on equipment. It’s the same modeling discipline behind every pipeline program we design.

• Pipelines — Gas, Liquid and Multi-Phase — Gathering and sales pipeline design with rigorous hydraulic modelling across steel, polyethylene, fiberglass and composite systems.

Electrical Engineer

Unreliable power distribution, aging switchgear, or a plant that’s outgrown its electrical infrastructure all slow down production. Tundra’s electrical engineers handle everything from power distribution to PLC and SCADA integration, in-house, across Calgary and Houston. One team designs it, so nothing gets lost between disciplines.

• Electrical Engineering — Power distribution, switchgear and electrical infrastructure designed in-house alongside the rest of the project team.
• Automation and Control Systems — Control system architecture and integration that connects field instrumentation to the way the plant is actually run.
• PLC System Design and Programming — Control logic, panel and I/O design, interlocks and shutdown philosophy developed in the platforms already installed at your sites.
• SCADA & Remote Operations Engineering — SCADA architecture, operator screens, historians and alarm rationalization, including platform upgrades on assets that have to stay visible throughout.
• RTU System Design and Programming — Remote terminal unit specification, register mapping and secure telemetry back to the control room over cellular, radio or satellite links.
• Field Programming, Automation & eCommissioning Services — On-site loop checks, point-to-point verification, cause-and-effect testing and loop tuning through startup and the first weeks of operation.

Industrial Engineer

Facilities that were never designed to run at their current throughput end up with layouts and utility systems working against the people operating them. Our industrial engineering work in Calgary and Houston focuses on how a plant is actually operated and maintained, not just how it’s built. That’s the difference between a facility that runs and one that merely gets commissioned.

• OH&S — Safe Operating Procedures — Operating procedures written for the people running the plant, tied to the equipment as installed.
• Plant Turnarounds and Planned Shutdowns — Turnaround scoping, planning and execution support that keeps the outage window realistic.

Mechanical Engineer

Rotating equipment failures, piping stress issues, and skid packages that don’t fit the site are mechanical problems that surface long after startup if they’re not caught early. Our mechanical engineers in Calgary and Houston cover piping, equipment selection, and pressure systems for projects from a single MOC to a full plant expansion. Every mechanical discipline sits under the same roof as the rest of the project team.

• Gas Compression and Compressor Stations — Compression design and station engineering, from a single unit to a full station rebuild.
• Pumps and Rotating Equipment — Pump selection, rotating equipment specification and the piping and stress work that keeps them running.
• Flare Mitigation — Engineering to cut routine flaring and vent volumes while keeping the facility operable.
• EPAP Programs — Enhanced Production Audit Program support covering measurement accuracy, volumetric validation and production accountability for regulatory reporting.
• Maintenance Management — Maintenance strategy and program development built around how the equipment actually fails.
• Integrity Management — Integrity programs for pressure equipment and pipelines, covering inspection planning through records.

Environmental Engineer

Flaring, fugitive emissions, and regulatory reporting are getting harder to manage without a real environmental strategy, not just a compliance checklist. Tundra’s environmental engineers work alongside our regulatory team in Calgary and Houston to handle emissions management and AER submissions as part of the same project, not a separate consultant. That keeps one team accountable for the whole outcome.

• Environmental Consulting — Environmental strategy delivered inside the project rather than bolted on by a separate consultant.
• Asset Retirement — Suspension, abandonment and reclamation engineering for licence obligations with dates attached.
• Regulatory Submissions — Application and submission preparation for AER and equivalent regulators, handled by the same team doing the engineering.

Petrochemical Engineering Service

Petrochemical facilities carry tighter process margins and higher consequence-of-failure than typical energy infrastructure, which calls for engineers who’ve worked in both worlds. Tundra brings the same EPCM discipline we apply to gas plants and pipelines to petrochemical-adjacent projects across Calgary and Houston. No project is too specialized for our in-house, full-discipline team.

• Oil Batteries and Oil Treating — Battery design and treating systems that prepare upstream oil well effluent for transport and sale.
