The quickest way to guarantee an interesting day on a construction site:

Say, “This should be easy.” 😂

Every time someone turns on a faucet, there is an entire system beneath the surface making it possible.

A dependable waterline requires more than placing pipe in a trench. Proper depth, alignment, bedding, secure connections, pressure testing and careful backfill all play a part in protecting the system for years to come.

At Under The Mountain Underground, we understand that the work we install underground directly affects the homes, businesses and communities above it.

It may be buried when the job is finished—but the quality of the installation should never be forgotten.

Built underground. Trusted above ground.

📏 CLOSE ENOUGH ISN’T CLOSE ENOUGH UNDERGROUND.

The pipe may be the most visible part of an installation, but long-term performance depends on everything surrounding it.

Proper grade.
Correct alignment.
Stable bedding.
Secure connections.
Controlled backfill and compaction.

A small error at the beginning of a utility run can become a much larger problem farther down the line. That is why our crews continuously check elevations, measurements and site conditions throughout the installation—not only when the work is finished.

Measure it. Check it. Install it right.

Because once the work is buried, “close enough” gets expensive.

SEPTEMBER IS NATIONAL PREPAREDNESS MONTH

In excavation work, being prepared means much more than having the right equipment and an experienced crew. Safety must be considered long before the first bucket ever hits the ground.

At Under The Mountain Underground, our safety planning begins during the bidding process. Before committing to a project, we carefully review the plans, specifications, utility information and geotechnical reports to identify potential hazards and determine what will be required to perform the work safely.

That preparation includes evaluating:

• Existing and proposed utility conflicts
• Soil classifications and changing ground conditions
• Excavation depths and protective-system requirements
• Proper shoring, sloping or benching
• Safe access and egress
• Equipment positioning and swing-radius hazards
•Overhead crossings
• Spoil-pile placement and surcharge loads
• Traffic control and protection of the public
• Weather and groundwater conditions
• Emergency and rescue planning

Safety-related labor, equipment and protective measures must be accounted for before the job begins—not treated as an afterthought once the excavation is already open.

Once work begins, preparation continues through daily inspections, clear communication, competent-person oversight and constant awareness of changing site conditions. An excavation that was safe yesterday may require a completely different approach today.

At UTMU, we firmly believe in the construction version of the 5 Ps:

PROPER PLANNING
PREVENTS
PISS-POOR
PERFORMANCE

We also work by another simple motto:

“Fail to plan—and you had better plan to fail.”

Planning protects the project, but more importantly, it protects the people performing the work. Every member of the crew deserves to finish the day safely and return home to their family.

Plan the work.
Inspect the conditions.
Communicate clearly.
Work safely.

Most people will never see this part of the project once construction is complete.

This StormTech underground chamber system is designed to capture, temporarily store and manage stormwater beneath the finished site.

A successful installation requires careful excavation, proper foundation preparation, chamber placement, connections, geotextile and controlled stone placement. Once everything is completed and covered, the surface above can still be used—while the stormwater system quietly does its job underground.

Built correctly. Buried permanently.

🦒 WHAT’S ABOVE GROUND IS NOW OPEN—AND WE’RE PROUD OF WHAT WE HELPED BUILD UNDER IT.

The new Giraffe Center at Cheyenne Mountain Zoo is officially open to the public!

Double T Earthworks and Under The Mountain Underground LLC is proud to have partnered and performed underground utility work for this exciting Colorado Springs project.

Most visitors will never see the infrastructure beneath the new exhibit—and that means we did our job right.

Congratulations to Cheyenne Mountain Zoo and everyone involved in bringing this incredible new space to life.
