At Van Matre Construction, we’ve spent more than 20 years guiding homeowners, property managers, and fellow contractors through the maze of local building codes, ensuring every project is safe, compliant, and built to last.
Ready to take the guesswork out of your next project? Contact Van Matre Construction today for a code-compliant, stress-free excavation or shoring solution.
Why Local Building Codes and Permitting Matter for Excavation & Shoring
Let’s be honest: no one loves paperwork or red tape. But when it comes to excavation and shoring, building codes are your project’s best friend, not a hurdle. Local codes are there to keep you, your neighbors, and your investment safe.
As our founder often says,
“We believe in doing things right the first time. It’s not just about passing inspections, it’s about protecting families and properties for decades to come.”
That philosophy guides everything we do.
Ignoring or misunderstanding local regulations can mean costly delays, fines, or even putting your property and safety at risk. We know many clients feel overwhelmed by all the requirements, especially when every city seems to have its own rules. That’s why we’re here: to demystify the process, shoulder the burden, and make sure there are no surprises along the way.
Understanding the Regulatory Landscape in Colorado
How Building Codes Work in Denver and Surrounding Areas
Colorado isn’t a one-size-fits-all state when it comes to building codes. Each city and county, Denver, Boulder, Lafayette, Broomfield, Arvada, Louisville, and Westminster, has its own approach, amendments, and permitting quirks.
- Denver: Follows the 2025 Denver Building and Fire Codes, which are based on the latest international I-codes with local amendments. The National Electrical Code (NEC) is adopted statewide, but Denver applies its own updates.
- Neighboring Cities: While most follow similar I-code frameworks, the specifics (like required documentation, timelines, and inspection processes) can differ. For example, some municipalities require permits for any excavation over 10 cubic yards, while others use surface area or depth as the trigger.
If you’re not sure which rules apply, don't worry. We've navigated every one of these jurisdictions and can help you get it right the first time.
Key Agencies and Authorities
For most projects, you’ll be dealing with the city’s Community Planning and Development (CPD) department (or its equivalent). In Denver, that’s the main hub for permits, code updates, and inspections. Other municipalities have their own planning or building departments.
On the safety side, the Occupational Safety and Health Administration (OSHA) governs shoring and trenching practices. We stay current on all OSHA regulations and local amendments, so you don’t have to.

Step-by-Step: How to Secure Excavation Permits in Colorado
Navigating the permit process can feel like a marathon, but it doesn’t have to be. Here’s how we help clients get it done right, every time.
The General Process
- Determine Jurisdiction: Is your project in Denver, Boulder, or another city? Each has its own process.
- Prepare Documentation: This typically includes a site plan, scope of work, proof of insurance, and sometimes a traffic control or erosion plan.
- Complete the Application: Submit through the local portal or in person.
- Pay Fees and Secure Bonding: Fees and bond requirements vary by city and project size.
- Call 811 Before Digging: It’s the law; utility location services must mark underground lines at least three business days before you dig.
- Schedule Inspections: Some permits require pre-approval inspections or ongoing site visits.
Van Matre Tip:
“We always double-check every document before submission, because missing paperwork is the #1 reason for delays. Our clients appreciate that we sweat the small stuff, so they don’t have to.”
Common Pitfalls and How to Avoid Them
- Incomplete Applications: Missing a single signature or insurance certificate can set you back days or weeks.
- Not Calling 811: Failing to mark utilities can result in hefty fines and serious safety risks.
- Misunderstanding Permit Triggers: Some cities require permits for surprisingly small projects; always check before you dig.
- Delaying Inspections: Waiting until the last minute to schedule can put your whole project on hold.
Our Promise:
We’ve seen it all, and we’re here to make sure your project moves forward smoothly, no surprises, no headaches.
Shoring Regulations and Safe Excavation Practices
When and Why Shoring Is Required
Shoring isn’t just a best practice, it’s the law for many projects. In Colorado (and per OSHA), any trench or excavation 5 feet deep or more requires a protective system, unless the excavation is made entirely in stable rock.
But it’s not just about depth. We always assess:
- Soil Type: Some soils are more prone to collapse.
- Proximity to Structures: Adjacent buildings or roads can affect stability.
- Weather Conditions: Rain, snow, and freeze-thaw cycles change everything.
“Our approach is simple: safety first, always. If there’s any doubt, we err on the side of more protection, not less.”
Types of Shoring Systems Used in Colorado
We use a variety of shoring systems, each chosen for the specific site conditions and project requirements:
- Hydraulic Shoring: Our preferred system for most projects, fast, safe, and minimizes the need for workers to enter the trench.
- Pneumatic Shoring: Similar to hydraulic, but uses air pressure.
- Timber Shoring: Still a good option for certain situations, though less common.
- Shielding (Trench Boxes): Ideal for linear utility work.
“We invest in the best equipment and technology because our clients deserve peace of mind. It’s not just about passing inspection, it’s about sending everyone home safe at the end of the day.”
Inspection, Maintenance, and Documentation
Safety doesn’t stop once the shoring is in place. We:
- Inspect Daily: Every shoring system is checked at least once per shift, and always after rain or site changes.
- Keep Detailed Logs: Our team documents every inspection, so there’s a clear record for you and the city.
- Assign a Competent Person: Every project has a trained expert responsible for site safety and compliance.
“We handle all the documentation and inspections so our clients can focus on what matters: their project, their property, and their peace of mind.”
