Design work in a city laid out on a grid

Calgary is one of the few large cities in Canada that a stranger can navigate on arithmetic alone. The street grid is split into four quadrants around Centre Street and the Bow River, avenues run east to west and streets north to south, and an address tells you almost exactly where you are standing. It is a very engineered arrangement for a place that started as a fur and cattle stop, and it says something about the local temperament: this is a city that prefers a system you can reason about to a picturesque muddle. Our design engineering group works the same way. Wellsites, pads, plant modifications and scan-based models are all exercises in imposing a legible order on something that will be built, operated and modified by people who were not in the room when it was drawn.

The skyline gives you the other half of the picture. The Calgary Tower, finished for the country’s centennial in 1967, was the tallest structure in the city for a quarter century and is now comfortably outgrown by the towers around it. The Saddledome’s hyperbolic paraboloid roof, built for the 1988 Winter Olympics, is still one of the most elegant pieces of structural design in the country, and the ski jumps at Canada Olympic Park are visible from the west end of the Trans-Canada like a pair of exclamation marks. Calgary likes ambitious geometry. It also expects it to be finished on schedule and on budget, because the money came from somewhere specific and somebody has to answer for it.

Wellsites and multi-well pads

Modern Alberta development is a pad business. Instead of scattering single wells across a section, operators drill six, twelve or twenty horizontals from one surface location, which concentrates the equipment, the traffic, the noise and the risk into a single well-designed footprint. That concentration is the whole point — less surface disturbance, fewer lease roads, one set of utilities — but it makes the layout decisions much less forgiving. Spacing between wellheads, separator and treater placement, tank farm containment, flare and vent radiation, truck turning circles, electrical classification boundaries and the prevailing wind all interact, and a compromise made early to save a few metres will be paid for every day of the pad’s life.

Tundra designs wellsites and multi-well pads from the plot plan outward: process and mechanical layout, piping and hydraulics, measurement, electrical and instrumentation, and the drawing package the construction contractor actually needs. We design for the operator who has to walk the site at minus thirty in the dark, not for the render. Alberta’s setback and spacing requirements set the floor; the useful design work happens above it, in the decisions about maintenance access, future tie-in provisions and what happens on the day a workover rig has to get in beside live equipment.

Suspended well programs

Alberta has a large inventory of wells that are neither producing nor abandoned, and the regulator has steadily tightened what is expected of operators who leave them in that state. A suspended well is not a dormant one; it carries obligations for downhole and surface condition, testing, signage, security, site maintenance and periodic inspection, and the Alberta Energy Regulator’s Directive 013 and the associated licensee liability framework have made the consequences of neglect concrete.

Our suspended well work is largely about turning a scattered inventory into a defensible plan: assessing the condition and risk of each well, sequencing the suspension, reclamation or abandonment work so that the crews and equipment are used efficiently across a field rather than one lease at a time, and producing documentation that will survive an audit or a change of ownership. It is not glamorous, but in a province where liability management ratings determine whether a company can transact at all, it is often the most valuable engineering a small operator buys in a given year.

Plant debottlenecking

Calgary rebuilds rather than expands wherever it can. The Beltline and Inglewood have absorbed enormous growth without pushing the city outward, the East Village went from a written-off district to a neighbourhood with a landmark library, and the Central Library itself was threaded over a working LRT line rather than moved somewhere easier. Debottlenecking is the industrial version of that instinct: find the constraint, fix the constraint, and get more out of the asset you already own instead of building a new one.

The discipline is in the diagnosis. Operators usually know their plant is limited, and they are usually wrong about where. The constraint that shows up in the control room as a compressor limit turns out to be a cooler, a control valve, a relief scenario or a liquid handling problem three units upstream. Tundra approaches debottlenecking with a rate-based process model, field data that has been reconciled rather than assumed, and a hydraulic review of the whole system, then tests the candidate fixes against capital cost, shutdown duration and the change in the relief and flare load. Frequently the answer is unromantic — a control philosophy change, a different pump internal, an extra exchanger pass — and worth several times what a new unit would have returned.

3D laser scanning

Scanning has quietly become the most cost-effective hour in brownfield design. A scan crew walks a congested unit, and what comes back is a point cloud accurate to a few millimetres that can be measured, modelled against and shared. Every clash caught in the model is a field rework avoided, and in a province where a winter tie-in window may be measured in days, avoided rework is the whole game.

We use scanning to build as-built models of existing facilities, to check fabricated spools before they leave the shop, to verify structural and foundation conditions, and to give a design team a plant they can walk through from a desk in Calgary rather than a description assembled from photographs and memory. It also solves an argument. When the pipe rack is fifty millimetres from where the drawing says it is, the point cloud settles it before anyone has bought steel.

The local advantage

Designing from Calgary means designing close to the people who will build. Fabrication shops in the Foothills Industrial Park, module yards north of the city and the contractors who staff a shutdown are all inside an hour, and the difference between a design that is buildable and one that is merely correct usually comes from a shop visit rather than a specification. It also means designing for Alberta weather, where the construction window is short, the ground moves, and everything on a pad has to be operable in mitts.

The city itself makes the case for the trade. Between Fish Creek Provincial Park in the south, Nose Hill in the north and the Rockies an hour west, Calgary keeps hold of engineers who could earn more somewhere flatter and duller. That retention is why a design team here can carry twenty years of Alberta-specific judgement, and why the drawings that leave this office tend to look like they were produced by people who have stood in the mud.

Whether it is a new pad, an inventory of suspended wells that has become a liability problem, a plant that has quietly run out of room, or a facility nobody has an accurate model of, the design group in Calgary would rather start with the site than the spreadsheet.

Drawings people can build from

The measure of a design package is not how it looks in a review meeting. It is how many questions the construction crew has to ask. We aim for packages that a competent contractor can price accurately and build without inventing details, which means complete bills of material, dimensions that actually locate things, tie-in details drawn rather than described, and a discipline check that happens before issue instead of in the field.

Calgary has strong opinions about built quality because it can see the results from anywhere. The skyline is compact and legible — Bankers Hall, the curve of The Bow, the fractured glass of Telus Sky and Jaume Plensa’s enormous wire-mesh head sculpture at its base, all visible from the top of the hill on Crowchild. When something is done well here, the whole city looks at it for the next forty years. When it is done badly, the same applies.

We take the same view of a plot plan. A pad or a plant modification will be operated, maintained and eventually decommissioned by people who were not consulted about the layout, and the decisions made in an afternoon at a desk will inconvenience or assist them every day for decades. Designing for that person — the operator in the dark at minus thirty, the millwright who needs to pull a bundle, the crew who will tie in the next well — is the difference between a drawing that is correct and a design that is good.
