Lockerbie & Hole

What Lockerbie & Hole does

Lockerbie & Hole is a privately held mechanical construction contractor headquartered in Calgary, Canada. According to its company-registered description, it is the largest mechanical construction contractor in Canada. The firm was founded in 1898, placing it in continuous operation for over 125 years, and maintains a corporate web presence at https://www.lockerbiehole.com. The "mechanical construction" designation situates the company in the trade scope that typically encompasses HVAC, plumbing, piping, fire protection, and industrial mechanical systems for commercial, institutional, and industrial facilities, though the specific service mix, project verticals, and customer roster are not detailed in the input data supplied for this analysis.

No financial disclosure (revenue, headcount, backlog, project count), no management-team roster, no customer-logo list, and no product/service catalogue were available for Lockerbie & Hole within the provided input. The aggregated corpus does include a substantial block on Aecon Group Inc., a separately incorporated Canadian construction and infrastructure firm (TSX:ARE, founded 1877), but those facts belong to a distinct legal entity and have not been used to characterize Lockerbie & Hole's operations, revenue model, or strategic positioning. The available evidence therefore supports a narrow description limited to corporate identity, sector classification, geography, longevity, and scale claim, while deeper operational, financial, and customer details remain unsupported by the input.
