Westco Construction

What Westco Construction does

Westco Construction Ltd. is a private design-build construction firm founded in 1991 and headquartered in Lethbridge, Alberta, serving agricultural, commercial, and industrial clients across Western Canada. The company operates on a single-contract design-build model that integrates architects, engineers, estimators, and builders under one accountable team, offering design-build, construction management, and general contracting services. Its portfolio is anchored in Southern Alberta's agricultural economy — including potato storage and loadout facilities for Quattro Farms (85,200 sq ft), Grassy Lake Potato Company (79,343 sq ft), Chin Coulee Spud Farms (22,500 sq ft), and a high-bay freezer for Cavendish Farms (38,295 sq ft) — alongside commercial dealership builds for Toyota Canada and Hyundai Canada, and a separate Westco Rentals equipment rental division (rent.westco-rentals.ca) providing daily, weekly, and monthly rentals of construction, industrial, and agricultural equipment.

The firm is founder-owned and operated by Derek O'Connor (President, co-founder) and Theo Van Ee (Principal/Sales, co-founder), with second-generation family members in operating roles (Jason Van Ee as General Manager, Marty Van Ee as Operations Manager, Darren Slomp as Construction Manager, both promoted December 2024). Revenue is generated primarily through one-time project fees (quote-based, not publicly disclosed) for individual construction projects, supplemented by usage-based equipment rental revenue from Westco Rentals. The go-to-market motion is sales-led and direct, with free estimates, a website inquiry flow, and a secondary rental portal as lower-funnel lead sources. The customer base is concentrated in agricultural enterprise accounts in Southern Alberta and a small set of branded commercial clients, with 100+ completed projects and 90+ referenced customers over 35 years.

The company added a Fort MacLeod branch office in 2025 and created its first Director of Business Development role in March 2025, signals consistent with a controlled, organic expansion stance. The firm holds no external funding, has no parent company, and operates as a private limited company domiciled in Alberta, with 51-100 employees including estimators, drafters, project managers, foremen, site supervisors, and trade-certified field personnel (Journeyman Red Seal Carpenters, Ironworkers, Metal Building Systems Erectors). No AI, software, or technology-platform capabilities are disclosed; the technology stack is conventional design-build methodology with specialization in steel structures and insulated metal panel building envelopes.
