A modular office building is an office built as finished sections inside a factory, then delivered to its site and set in days on a permanent foundation or a steel skid. It is built to the same code as a site-built office: Herauf's offices meet or exceed CSA A277 and the National Building Code, with electric heat standard and solar optional.
For Regina and southern Saskatchewan, the page to read is commercial modular buildings in Regina, since those offices are built at the 35,000 sq ft Zehner plant about twenty minutes northeast of the city. The full commercial range, and every delivered commercial project, is on the commercial modular buildings page. This article covers the office sizes and how to choose between them.
What sizes does a modular office come in?
The commercial catalogue has three office buildings, smallest to largest:
- Safety office, 30' × 14'. The smallest office in the catalogue.
- Site office, 40' × 18'. The standard office for a lease, a camp or a project site.
- Office, 55' × 18'. Five offices, a boardroom and a kitchenette in one building.
For remote sites there is also on-site quarters at 42' × 14', which puts a bedroom, an office and two washrooms in one unit with self-contained water and waste. Every configuration starts from a proven layout and is changed to suit; the full list is in the commercial catalogue.
Skid or foundation: which does an office need?
It depends on whether the office has to move. Site offices and safety offices are usually built on a steel skid with self-contained plumbing, electrical and HVAC, so the building can be lifted and relocated when the project moves. An office meant to stay where it is sets on a permanent foundation instead. Decide this at the start: a unit is relocatable when it is specified that way from the beginning, because the skid is welded in Herauf's own shop and travels under the building from the plant floor.
How long does a modular office take?
About 16 weeks from order to delivery for most builds, up to 50% faster than conventional construction. The time comes back because the two jobs run at once: your ground work happens while the office is framed, wired and finished indoors. When it arrives, the crew is on your site for days rather than months. The week-by-week version is in how fast modular construction is.
What code is a modular office built to?
Each unit meets or exceeds CSA A277 and the National Building Code for climate zones 6 through 8, and is inspected at every stage of production through to installation. Building indoors also removes weather delays from the schedule. What CSA A277 covers is explained separately.
Which offices has Herauf delivered?
Four of the commercial projects on the site are offices:
- Surge Energy site office, Wainwright, Alberta: a durable, accessible modular site office built off-site and delivered ready to operate for an oil and gas operation.
- Suncrest College agricultural office, Yorkton, Saskatchewan: built off-site and delivered ready to occupy.
- Federated Co-op agro centre office, Neepawa, Manitoba: precision-built indoors and finished before it left the plant.
- St. Theresa Point child and family services office, Winnipeg, Manitoba: manufactured off-site and delivered complete.
Site offices for oil, gas and industrial work are grouped on the industrial section of the commercial page.

Common questions
What is a modular office building?
An office built as finished sections inside a factory, inspected at every stage of production, then delivered to its site and set in days on a permanent foundation or a steel skid. Herauf's offices meet or exceed CSA A277 and the National Building Code for climate zones 6 through 8.
What sizes do modular offices come in?
Herauf's published commercial catalogue runs from a 30' × 14' safety office and a 40' × 18' site office to a 55' × 18' office building with five offices, a boardroom and a kitchenette. On-site quarters at 42' × 14' combine a bedroom, an office and two washrooms with self-contained water and waste.
How long does a modular office building take?
Most Herauf builds are manufactured and delivered in about 16 weeks, up to 50% faster than conventional construction, because site work runs in parallel with production. Once the finished building arrives, installation is measured in days.
Can a modular office be moved later?
Yes, when it is specified that way. A steel-skid portable foundation with self-contained plumbing, electrical and HVAC lets the unit be lifted and relocated, which is why site offices and safety offices are usually built on skids.
