Redclay Excavating provides mass grading services Colorado developers, builders, and contractors rely on. We handle large-scale earthmoving, cutting high areas, filling low areas, and compacting soil, to prepare any site for residential, commercial, or industrial construction across the Colorado Front Range and beyond.

From rough grading and cut and fill operations to over-excavation and soil stabilization, our team delivers precise, compliant results on time and within budget. Updated for 2026, our processes meet current CDOT and local permitting requirements throughout Colorado.

Redclay Excavating offers Mass Over-lot Grading and Excavation. Any sized over-excavation, soil stabilization. bank cut and fill.

Excavation Perfection

Mass Grading

Redclay Excavating specializes in mass grading operations for industrial, commercial, and residential projects. Our team delivers precision-driven excavation solutions supported by extensive experience and advanced technology.

Our capabilities extend beyond mass grading and over-excavation to include underground storage tank excavation, settling pond excavation, land clearing, pond excavation, over-excavation and soil stabilization, excavation shoring, road excavation and construction, underground utility excavation, and oil and gas pipeline excavation.

We leverage advanced GPS-equipped machinery, rover and data collection technology, and in-house 3D project modeling to execute excavation work with exceptional accuracy and efficiency.

Why This Matters

Our technology-driven approach significantly reduces the need for continuous surveying throughout the excavation process. With as few as three survey control points, our team can manage the remainder of the work independently — saving clients thousands of dollars in survey costs while improving productivity, minimizing delays, and keeping projects on schedule.

Building Relationships

A Mass Grading Contractor Colorado Trusts

Redclay Excavating has the crew, the equipment, and the track record. Our project managers, superintendents, and operators deliver mass grading services Colorado clients count on — safely, on time, and within budget.

We've completed commercial grading Colorado projects ranging from large residential subdivisions to industrial pads and DOT roadway sections. Every project gets the same commitment: clear communication, documented results, and work that holds up.

Service 01

  • Evaluation and removal of unsuitable, soft, or unstable subgrade materials
  • Excavation to specified depths below finished subgrade or foundation elevation
  • Placement and compaction of approved select or engineered fill materials
  • Moisture conditioning to achieve optimum moisture content
  • Compaction to specified density requirements per ASTM and DOT standards
  • Lime, cement, or fly ash soil stabilization (as specified)
  • Proof rolling and coordination with geotechnical testing agencies
  • Fine grading to plan lines, grades, and tolerances
  • Clearing, grubbing, and stripping of vegetation and topsoil
  • Bulk earthwork excavation and embankment construction
  • Cut-and-fill operations in accordance with approved grading plans
  • Placement of fill in controlled lifts per geotechnical recommendations
  • Balancing of on-site cut and fill materials, import/export as required
  • Rough grading for building pads, roadways, and site infrastructure
  • Erosion and sediment control implementation during grading operations
  • Coordination with surveying and geotechnical testing agencies

Service 02

Mass Grading Operations

DOT and geotechnical-compliant bulk earthwork — reshaping an entire site to design subgrade elevations with balanced cut-and-fill and full compliance documentation.

The Basics

What Is Mass Grading?

Mass grading is the large-scale reshaping of land before construction begins. It involves moving significant volumes of soil to establish a stable, level foundation across an entire site, not just a small area.

Unlike standard excavation, which focuses on digging specific trenches or footings, mass grading and site preparation reshape the entire terrain. Crews cut down high spots and use that material to fill low spots — a process called cut and fill grading Colorado contractors must plan carefully to balance earthwork volumes and reduce hauling costs.

A mass grading plan, prepared by a civil engineer, sets the target elevations, slope ratios, and drainage patterns the grading team must achieve. Redclay Excavating works directly from these engineered plans to deliver accurate, DOT-compliant results on every project.

01

Site Survey & Grading Plan Review

Our team reviews the engineered grading plan and establishes GPS control points across the site. This sets the baseline for all cut and fill operations that follow.

02

Clearing, Grubbing & Topsoil Stripping

We remove vegetation, roots, and unsuitable surface materials before any earthwork begins. Topsoil is stockpiled for reuse during finish grading operations at the end of the project.

03

Bulk Earthwork & Cut and Fill Operations

Bulldozers, motor graders, and scrapers move large volumes of soil to match the design elevations. We balance on-site cut and fill materials wherever possible to reduce import and export costs.

04

Soil Compaction & Moisture Conditioning

Fill is placed in controlled lifts and compacted to ASTM and DOT density standards. Moisture conditioning ensures the soil reaches optimum compaction before the next lift is placed.

05

Drainage & Erosion Control

Stormwater management and erosion control measures are installed throughout the grading process, as required by Colorado state and local regulations.

Local Expertise

Why Proper Mass Grading Matters in Colorado

Colorado's climate and geology create unique challenges for any earthwork contractor. Expansive clay soils, high-altitude freeze-thaw cycles, and variable moisture levels all affect how a site behaves after grading, and how long a finished pad will hold up under a structure.

Our mass grading projects include specific soil testing and moisture conditioning steps designed for Front Range conditions. We account for seasonal ground movement, drainage requirements, and CDOT permitting standards so your site is ready for construction, not callbacks.

Proper commercial grading projects require thorough stormwater management planning. We implement erosion control measures from day one and coordinate with geotechnical testing agencies to document compaction results throughout the project.

Questions

Mass Grading FAQ

Mass grading follows a sequence of clearing, surveying, bulk earthmoving, compaction, and finish work. Our teams start with an engineered grading plan, then use GPS-guided equipment to cut and fill the site to precise elevations before final compaction and drainage work is completed.
No, though they are related. Excavation typically refers to digging specific areas like trenches or footings. Mass grading and earthwork covers reshaping an entire site's surface elevation. Both may be needed on the same project, and Redclay Excavating provides both as part of our site preparation services.
A mass grading plan is an engineered document prepared by a licensed civil engineer. It specifies target elevations, cut and fill volumes, slope ratios, and drainage patterns for the site. Our grading teams work directly from these plans to ensure every project meets design and regulatory requirements.
In Colorado, construction defect claims related to earthwork and grading are generally subject to a two-year discovery period and a six-year statute of repose under Colorado Revised Statutes. We carry full contractor liability coverage and document all compaction testing and inspection records to protect both our clients and our work.
