What Landmark Structures does

Landmark Structures is a North American engineering, procurement, and construction (EPC) firm specializing in large-scale water storage tanks, industrial pressure vessels, and specialty infrastructure. Founded in the 1970s and operated as Landmark Structures I, LP, the company self-reports as the '#1 Elevated Tank Provider' and has delivered more than 1.2 billion gallons of elevated water storage capacity across completed projects. It invented the Composite Elevated Tank (CET) and has built more CETs than all competitors combined while leading the development of national standards that support the product. The core product portfolio spans CET, Bolted Elevated Tanks (via partnership with CST Industries), Spheroid Elevated Tanks, Ground Storage Tanks, industrial API/ASME vessels, and special application tanks including thermal energy storage and surge protection.

The company operates an integrated project-delivery model, self-performing planning, engineering and design, procurement, fabrication (Decatur, Texas and Burlington, Ontario facilities), construction, and commissioning under multiple contracting methods — Progressive Design Build, Design Build, Construction Manager at Risk, Design Bid Build, and turnkey EPC. Post-construction, Landmark offers long-term recurring revenue through inspections, maintenance, protective coating systems, and a Tank Asset Management Program (TAMP) with 3–20+ year terms. Technical capabilities include in-house advanced finite element analysis, non-linear buckling modeling, soil-structure interaction, computational fluid dynamics, and proprietary construction equipment refined across more than 15,000 concrete wall segment placements.

Landmark serves four verticals: Water & Wastewater Utilities (primary — municipal storage, water hammer mitigation, reclaimed water), Oil & Gas (API/ASME vessels for hydrocarbon processing), Petrochemical (specialty vessels meeting stringent code), and Energy & Power (surge tanks, thermal energy storage, hydroelectric infrastructure). Notable customers include the Regional Municipality of York, Ontario Power Generation, Canadian Natural Resources Limited, the City of New Orleans, and Austin Water. Go-to-market is direct enterprise field sales with long, project-based sales cycles; the company is privately held under Landmark Structures I, LP and received investment from Graycliff Partners in April 2022.

Revenue model

1. Engineering, Procurement, and Construction (EPC) Services: Landmark Structures generates revenue primarily through large, custom engineering and construction projects. Services span the full project lifecycle: project planning, engineering and design, procurement, fabrication, construction, and commissioning. Revenue is project-based and can involve multi-year contracting methods including Progressive Design Build (PDB), Design Build (DB), Construction Manager at Risk (CMAR), Design Bid Build (DBB), and fully turnkey EPC.
2. Asset Management and Maintenance Services: Post-construction, Landmark offers ongoing asset management programs including inspections, condition assessments, turnkey maintenance and repair, protective coating systems, and Tank Asset Management Programs (TAMP). These services provide recurring revenue from existing client infrastructure over multi-year program periods (3–20+ years).
3. Custom Tank and Vessel Fabrication: Fabrication of tank and pressure vessel components, piping systems, structural assemblies, and large modules for external clients across the water, energy, and petrochemical industries. Certified under ASME, API, and AWS standards. Fabrication facilities supply both internal project needs and external customer orders.
