Our Services
Site Development
Overview
Full-scope site preparation, start to finish
Every successful build starts below grade. Our crews handle the full sequence, clearing and demolition, mass excavation, cut-and-fill grading, subgrade preparation, and stormwater management, so your vertical contractor arrives to a clean, compacted, code-ready pad. Because we self-perform the majority of scope, quality control and schedule stay in our hands, not a chain of subcontractors.
Full scope
Everything a site needs, under one contract
Site development isn’t one task. It’s a coordinated program. Kolb self-performs and manages the entire scope, so nothing falls between subcontractors.
Planning & Preconstruction
Before a machine moves, we engineer the plan, the budget, and the schedule.
- Project requirements & specifications
- Concept & design planning
- Budget preparation & management
- Risk identification & mitigation
Site Preparation & Earthwork
Clearing, grading, and building the pad your project stands on.
- Site establishment & staging
- Clearing, stripping & mass grading
- Cut-and-fill to design elevation
- Subgrade prep & engineered compaction
Utilities & Stormwater
Underground infrastructure installed in step with grading.
- Storm, sanitary & water line installation
- Drainage & detention
- Erosion control (SWPPP)
- Stormwater management
Quality, Safety & Compliance
The oversight that keeps a job inspection-ready and on schedule.
- Quality control
- Crew assembly & management
- Inspection coordination
- Compliance reporting
- Crew safety training
- Subcontractor coordination & reporting
Capabilities
What our site development crews deliver
Clearing & Grubbing
Site clearing, tree and stump removal, and demolition that open the site for work.
Mass Grading & Earthwork
GPS machine-controlled cut-and-fill and engineered compaction to exact design elevations.
Underground Utilities
Storm, sanitary, and water installed in step with grading: one efficient mobilization.
Erosion & Stormwater
SWPPP-compliant erosion control, detention, and drainage that keep the site permit-ready.
How we work
A sequenced approach, takeoff to handoff.
One team owns the site from the first plan review to the final inspection-ready pad.

Problems we solve
Hard sites are where we do our best work
01
Poor or unstable soils
Wet, soft, or unsuitable soils get engineered out, undercut, moisture-conditioned, and compacted, or stabilized in place, so you build on ground that holds.
02
Water & drainage
We manage stormwater, detention, and grading so the site drains correctly and stays permit-compliant from first storm to final inspection.
03
Tight, phased schedules
Self-performing grading and utilities in one mobilization means fewer handoffs, fewer delays, and a pad ready when your vertical crew is.
04
Environmental & regulatory compliance
Erosion control, SWPPP adherence, and documented reporting keep the job clean, compliant, and inspection-ready throughout.
Stable ground is the foundation of every build. We deliver it.
Safety
Safety is a culture, not a number.
For us, safety is more than an EMR figure. It’s how every crew shows up, every day. From daily planning and hazard analysis to ongoing crew training, we build safety into the work so our people go home safe and your project stays on track.
Daily hazard analysis
Every crew plans the work and the risks before it starts.
Ongoing safety training
Continuous training keeps our people sharp and certified.
Documented compliance
Full reporting and inspection coordination on every job.
