School Construction in Calgary and Alberta

School construction in Alberta follows rules that most commercial work does not. New public schools and major modernizations are funded by the province, and the school division or Alberta Infrastructure runs the procurement. Contractors are usually prequalified before they can bid, the design follows the division's own standards, and the opening date is the first day of school. Independent and charter schools have more freedom, but the building code treats the building the same way.

How public school projects are procured

For a provincially funded school, the owner is either the school division or Alberta Infrastructure, depending on how the project is delivered. Either way, the work is publicly tendered, and the owner usually prequalifies proponents first. Prequalification looks at safety certification such as COR, WCB-Alberta standing, bonding capacity, insurance, financial strength and relevant past projects.

That means a school board cannot simply hire a contractor it likes. If you are a public owner, the procurement rules decide the process. If you are an independent or charter school, a society or a private operator, you can choose a delivery model, including design-build, and engage a contractor before the design is complete.

Division design standards

Calgary's school divisions and other Alberta divisions keep their own design and technical standards. They cover room sizes, finishes that survive decades of use, mechanical and electrical systems that the division's maintenance staff already know, security hardware and network infrastructure. The province also sets space standards for how large each type of school should be for its enrolment.

Building to those standards is not optional, and it is the reason a school costs more per square foot than an office of the same size. The finishes are chosen to last thirty years of daily use, not ten.

Gymnasiums and long spans

The gym is the largest single room in most schools and the one that drives the structure. Long-span steel joists or trusses, tall block walls, a sprung sports floor, high-bay lighting, ventilation sized for a full room and acoustic treatment so a game does not sound like a train station. The gym is also often used by the community after hours, which affects how it is separated and secured from the rest of the school.

Controlled entry and security

Modern schools are designed so visitors enter one way, through a secure vestibule, and are seen by the office before they reach the classrooms. The outer doors open to a vestibule. The inner doors stay locked until staff release them. Classroom doors lock from inside. Card access, cameras and a public address system tie it together.

Retrofitting a controlled entry into an older school is a common smaller project. It usually means moving the office to the front door, adding a vestibule and new doors, and running access control and camera cabling through a building full of asbestos-era materials that need testing first.

Modernizations and additions

Many Alberta schools are being modernized rather than replaced: new mechanical systems, accessibility upgrades, new washrooms, modular classroom additions, and hazardous materials abatement in buildings from the 1960s and 70s. The constraint is the school year. Major work happens in the summer, and anything that runs into September has to be safely separated from students and staff.

We plan school work backwards from the first day of classes and the end of June, with the abatement, the noisy demolition and the work that affects building systems packed into July and August.

What school construction costs

Middle and high schools usually sit higher because of science labs, career and technology studies shops and larger gyms. Modernizations vary widely with the condition of the building, the amount of abatement and how much of the mechanical and electrical system is replaced.

Independent, charter and private schools

Independent and private schools are often built in existing buildings: an office, a church or a former retail plaza converted to a school. That is a change of use, and in Calgary it needs a Change of Use development permit and a building permit. A school is an assembly occupancy under the building code, so the conversion usually triggers upgrades to exits, fire alarm, sprinklers and washrooms. Check those before you buy or lease, because they can cost more than the interior work.

Science labs, shops and specialist rooms

Middle and high schools include rooms that act like small industrial or laboratory spaces. Science labs need gas, water, drainage, fume hoods and emergency eyewash stations. Career and technology studies spaces can include woodshops with dust collection, metal shops with welding exhaust, foods rooms with commercial-grade kitchens and cosmetology rooms with salon plumbing. Each has its own ventilation, power and safety needs, and they push the cost of secondary schools above elementary schools.

Modular classrooms

Alberta school divisions use modular classrooms to add capacity quickly. Modules are built in a factory and connected to the school by a link corridor, with foundations, utilities, fire alarm and access control extended from the main building. The site work, the connection to the school and the code review of the combined building are where a contractor's work lies.

Modules are usually installed in the summer, so the site work, foundations and service connections have to be ready before the modules arrive.

Energy and indoor air

Schools are occupied by many people for long hours, so ventilation and indoor air quality matter. Current division standards typically call for ventilation with heat recovery, good daylight, and controls the maintenance staff can operate. Energy performance targets are common in new public schools, which affects the envelope, glazing and mechanical design.

Working with the school year

For modernizations, the calendar is fixed. Summer is short, and abatement, demolition, mechanical shutdowns and floor finishing all compete for those weeks. We plan the work so materials with long lead times are on site before school ends, and crews can start the day after the last class.
