What Gs Construction does
GS Construction is a privately held, family-owned underground infrastructure contractor founded in 1974 and headquartered in Acheson, Alberta. The company specialises in the construction and rehabilitation of water, wastewater, stormwater, and drainage systems for municipal, utility, and private developer clients across Western Canada. Its service portfolio comprises six integrated offerings: drainage services, infrastructure rehabilitation, land development, general contracting, water services, and maintenance and emergency repairs. GS operates 15 main underground crews and a fleet of 100+ trucks and heavy equipment, deploying specialised techniques including trench shoring systems (slide rail, tunnel plate liners), horizontal directional drilling, and auger boring for trenchless installations under obstacles such as rail tracks and waterways.
The company operates a sales-led, project-based business model, generating revenue primarily through competitive bidding on public RFPs and tenders and through long-term Master Service Agreements with anchor clients. EPCOR Water Services is its largest and most important customer under a Master Service Agreement established in 2018. Other significant clients include the City of Fort Saskatchewan, City of Spruce Grove, Municipality of Jasper, City of Wetaskiwin, Strathcona County, Alberta Capital Region Wastewater Commission, MacEwan University, and Amazon. The company also serves as a subcontractor on tier-one projects including the Valley Line West LRT (with Marigold Infrastructure Partners) and EPCOR's Outfall Control Gates flood mitigation program (with PCL Construction). Leadership is concentrated within the founding Sandwith family, with founder Glen Sandwith's son Terran serving as CEO and long-tenured operators like Mike Durdle (President) and Ryan Thompson (SVP) holding key executive roles. The company employs 200+ permanent and seasonal staff and has completed over 500 projects across its 50-year operating history.

Gs Construction competitors and assessment
Company assessmentRegional players
- North American Construction Group: Alberta-headquartered heavy construction and industrial services provider. Comparable regional presence and heavy-equipment-intensive model, though more focused on oil sands and industrial site work than municipal underground.
Broad incumbents
- Ledcor Group: Western Canada-rooted, employee-owned construction company with civil infrastructure and utilities divisions. Comparable scale and regional focus with overlapping municipal water/sewer bid pool.
- PCL Construction: One of Canada's largest general contractors with a major Edmonton infrastructure presence. PCL is already a GS partner (EPCOR Outfall Control Gates), but competes for the same large municipal and utility underground work at a national scale.
- Aecon Group: Major Canadian construction and infrastructure company active in civil, utility, and transit work. Comparable as a broad incumbent pursuing municipal water/wastewater and LRT projects overlapping with GS's core markets.
- Graham Construction: Western Canada-headquartered construction firm with significant civil infrastructure and water/wastewater capabilities. Comparable geographic concentration and pursuit of municipal infrastructure work in Alberta and BC.
- EllisDon Corporation: Major Canadian construction services firm with civil infrastructure capabilities. Comparable as a broad incumbent pursuing municipal and transit work; competes in similar bid pools for public sector contracts.
Direct peers
- Michels Corporation: US-based specialty contractor focused on underground infrastructure including HDD, tunneling, and pipeline construction. Comparable specialty technical capabilities (trenchless, deep excavation) that overlap with GS's most differentiated offerings.
- Maple Reinders: Canadian construction company with significant civil, environmental, and water/wastewater infrastructure expertise. Comparable mid-sized specialty contractor model focused on municipal and industrial underground work.
- Sure-Line Construction: Alberta-based underground utility and earthworks contractor serving Edmonton-area municipalities and developers. Direct regional peer competing in the same shallow/deep utility bid pool and EPCOR subcontractor ecosystem.
- Whissell Contracting: Calgary-based heavy civil and underground infrastructure contractor serving Alberta municipalities and developers. Directly comparable to GS in size, geography, and service mix (water, sewer, drainage, land development) with similar project-based bidding model.
