About Tanco Engineering Inc.
Tanco Engineering was founded in 1979 and is headquartered in Loveland, Colorado. Its core business involves the construction, repair, modification, and maintenance of aboveground storage tanks.
Although some sections of the company website still display “44+ years” of experience, a company founded in 1979 has operated for approximately 47 years as of 2026. This difference appears to be a website content update issue rather than a contradiction about the founding date.
The company highlights four central priorities:
- Safety
- Reliable execution
- Construction quality
- Clear customer communication
Tanco Engineering also emphasizes environmental responsibility, trained field personnel, technical expertise, and long-term customer relationships.
Who Owns Tanco Engineering?
LT Corporation announced its acquisition of Tanco Engineering in June 2025. LT Corporation is a parent company with businesses operating in steel fabrication, propane equipment, pressure vessels, metal manufacturing, and related industrial markets.
Tanco Engineering continues to operate under its established name and storage tank specialization. According to the acquisition announcement, joining LT Corporation was intended to support expansion while preserving Tanco’s existing leadership, workforce, customer relationships, and operating experience.
This ownership update matters because an About Us review should consider both the company’s historical identity and its current corporate structure.

Industries Served by Tanco Engineering
Tanco Engineering works across industries that depend on bulk liquid or material storage.
Energy, Petroleum and Power
Energy facilities require tanks for fuels, petroleum products, process liquids, reserve supplies, and other operational materials.
Tank failures or maintenance delays can interrupt production and create safety, financial, and environmental consequences. Tanco Engineering provides new construction and maintenance services for active energy and petroleum facilities.
Municipal Water and Wastewater

Food and beverage projects may require additional attention to material compatibility, cleaning procedures, contamination controls, coatings, and production continuity.
The Tanco Project Management Process
Tanco Engineering provides in-house project management for both new construction and repair projects.
The process is organized around four common phases:
- Initiation
- Planning
- Execution
- Closure
Customers are assigned a primary project manager who acts as a single point of contact. This person coordinates communication, schedules, project details, progress updates, safety information, and quality documentation.
Initial Project Review
The company begins by reviewing site information or project documentation.
Customers should be prepared to provide:
- Tank dimensions
- Stored product
- Tank drawings
- Inspection reports
- Required design standard
- Site location
- Desired completion date
- Operational restrictions
- Known damage or maintenance issues
- Required accessories or modifications
Incomplete documentation can lead to assumptions, exclusions, change orders, or delays. Providing accurate information at the beginning usually produces a more useful proposal.
Proposal Development
After reviewing the available information, Tanco Engineering prepares a proposal package that may include preliminary designs, scope identification, pricing, and project requirements.
A customer should confirm exactly what is included in the proposal rather than comparing contractors by total price alone.
Important areas to review include:
- Engineering responsibility
- Material specifications
- Coating or lining work
- Inspection and testing
- Site preparation
- Foundations
- Equipment access
- Waste disposal
- Permits
- Travel and mobilization
- Schedule assumptions
- Warranty terms
Reporting and Communication
Tanco Engineering states that it can provide daily, weekly, monthly, and final project reporting.
Reports may include:
- Progress tracking
- Site photographs
- Safety information
- Quality data
- Schedule status
- Completed activities
- Upcoming work
This reporting structure can be valuable for plant managers, engineers, procurement teams, and owners who cannot remain at the project site throughout construction.
Tanco Engineering’s Safety Record
Safety is one of the most prominent themes across tancoeng.com.
The company has an internal quality and safety department and says employees receive training in recognizing, preventing, and eliminating workplace hazards.
Tanco Engineering’s published safety page reports the following figures:
| Year | EMR | TRIR |
| 2021 | 0.67 | 0.00 |
| 2022 | 0.70 | 0.66 |
| 2023 | 0.69 | 0.00 |
| 2024 | 0.69 | 0.00 |
| 2025 | 0.68 | 0.00 |
The website categorizes an EMR between 0.00 and 0.75 as excellent. Its reported 2025 EMR of 0.68 falls within that published range.
Prospective customers should still request current safety documentation because performance figures, insurance records, certifications, and site-specific requirements can change.
What Makes the Tanco Experience Different?
Tanco Engineering uses the phrase “TANCO Experience” to describe its customer service and project delivery model.
The concept focuses on several practical benefits.
One Point of Contact
A dedicated project manager reduces confusion over who is responsible for answering questions, approving decisions, and communicating schedule changes.
This can be particularly valuable on projects involving engineering teams, plant operators, subcontractors, inspectors, safety personnel, and procurement departments.
In-House Engineering and Fabrication
Keeping engineering and fabrication within the same organization can improve coordination between the approved design and the components delivered to the site.
It may also help resolve design questions faster when unexpected field conditions appear.
Experienced Field Supervision
The company states that its supervisors average more than 15 years of experience. Experienced supervision is important because tank work requires careful control of welding, sequencing, tolerances, safety, lifting, inspection, and confined-space procedures.
National Capabilities
Tanco Engineering reports that its crews can travel throughout the country while remaining connected to core project management and customer locations.
LT Corporation’s acquisition announcement says Tanco’s services extend across the United States, including Alaska and Hawaii.

Questions to Ask Before Hiring Tanco Engineering
A strong company history does not replace a detailed review of the proposed project.
Ask the following questions before approving a bid:
Which Standard Will Govern the Tank?
Confirm whether the project will follow API 650, API 620, API 12D, AWWA, UL, or another applicable standard.
The selected code should match the tank’s intended service and regulatory requirements.
Who Is Responsible for Engineering?
Determine whether Tanco will provide stamped drawings, calculations, foundation design, accessory engineering, and approval support.
Also confirm which engineering responsibilities remain with the owner or another consultant.
What Is Excluded From the Proposal?
Common exclusions may include foundations, excavation, electrical work, coatings, insulation, permits, cranes, testing, piping connections, or disposal.
Every exclusion should be identified before contractors are compared.
How Will Shutdown Time Be Controlled?
For maintenance projects, ask how long the tank must remain empty and out of service.
Discuss cleaning, inspection access, repair sequencing, curing time, testing, and return-to-service procedures.
What Safety Documents Are Available?
Request current versions of:
- EMR documentation
- OSHA logs
- Insurance certificates
- Safety program information
- Training records
- Site-specific safety plans
- Confined-space procedures
- Subcontractor safety requirements
Who Will Manage Daily Communication?

A written communication plan can prevent delays and misunderstandings.
Common Mistakes to Avoid
Choosing a Contractor Based Only on Price
The lowest bid may exclude important engineering, inspection, testing, coating, access, or site work.
Compare the complete scope, not only the final number.
Failing to Provide Existing Tank Records
Missing drawings and inspection reports can make accurate pricing difficult.
Share as-built drawings, repair records, previous inspection findings, foundation details, product data, and operational history whenever available.
Ignoring Future Maintenance Access
A tank should not only work when it is new. It should also allow safe inspection, cleaning, seal replacement, coating work, and future repairs.
Discuss ladders, platforms, manways, roof access, drainage, and confined-space requirements during design.
Waiting Until a Tank Fails
Visible leaks and structural damage often begin as smaller maintenance problems.
Planned inspections and preventive repairs are usually easier to schedule than emergency shutdowns.
What the Website Could Explain More Clearly
Tancoeng.com provides extensive information about services and company values, but some details still require direct confirmation.
