C / 01Capability architecture

PURPOSE-BUILT FOR THE FIELD.

Four operating systems for tree, vegetation, storm, land, and debris missions.

C / 02System index

01SAG.TREE

Controlled arbor operations

02SAG.ROW

Vegetation & right-of-way

03SAG.STORM

Storm & access response

04SAG.LAND

Land & debris operations

SAG.TREE

Controlled arbor operations01

CONTROL THE HAZARD.

Technical tree operations planned around people, property, infrastructure, access, and consequence.

Operating principle

Planning accounts for work-zone control, equipment position, utilities, material flow, property protection, and clean handoff.

Applications

  • Hazardous & complex removals
  • Precision pruning & clearance
  • Rigging-supported operations
  • Facility & campus tree work
  • Risk and property-impact mitigation
  • Stump grinding & site closeout

SAG.ROW

Vegetation & right-of-way02

PROTECT THE CORRIDOR.

Project-based vegetation control where access, visibility, infrastructure protection, and documented completion matter.

Operating principle

Scopes are organized by corridor objective, site constraints, production method, recurring risk, and verification standard.

Applications

  • Roadside & access-area clearance
  • Utility-corridor support
  • Facility grounds & fence lines
  • Selective pruning & removals
  • Mechanical brush reduction
  • Hauling & disposal coordination

SAG.STORM

Storm & access response03

RESTORE THE ROUTE.

Priority-based response for emergency tree hazards, critical access, debris reduction, and post-event transition.

Operating principle

Initial access, hazard reduction, debris processing, hauling, and final cleanup are treated as distinct operating phases.

Applications

  • Emergency tree & limb removal
  • Critical access-route clearing
  • Storm debris reduction
  • Post-event hazard identification
  • Mobilization & staging plans
  • Production and photo records

SAG.LAND

Land & debris operations04

MOVE MATERIAL WITH PURPOSE.

Equipment, production sequence, hauling, and closeout aligned to the customer's access and end-state requirements.

Operating principle

The system considers material twice: where it is now and where it must finish, including every handling step between.

Applications

  • Land & lot clearing
  • Site preparation & access
  • Woody-debris removal
  • High-production chipping
  • Material handling & loading
  • Hauling, disposal & cleanup

C / 03Capacity layer

Capacity without fiction.

Equipment access is stated as access. Every resource is verified against the actual scope before proposal.

TREE HANDLING

Sennebogen 718

Access to 02Mechanized tree handling, controlled lifting, material positioning, and high-production support.

DEBRIS REDUCTION

Albach Chipper

Access to 01High-volume woody-debris processing where production, loading, and trucking must stay aligned.

SUPPORT FLEET

Scope-Aligned Resources

Project specificMultiple chippers, bucket trucks, material-moving equipment, professional rigging systems, hauling, and support resources.

C / 04Standards framework

Specifications built for the work.

Sentinel uses applicable ANSI A300-2023 performance standards as a framework when developing project-specific tree-care specifications, together with site conditions, contract requirements, manufacturer guidance, and qualified judgment.

ANSI A300 is a performance standard used to develop work specifications; it is not, by itself, a stand-alone specification for an individual project.

C / 05Execution controls

The work is technical. The control system is simple.

  1. 01

    Defined end state

    Everyone knows what complete, safe, and accepted means.

  2. 02

    Named responsibility

    Field, partner, and customer decisions have clear owners.

  3. 03

    Controlled change

    New hazards and scope changes are surfaced before they expand.

  4. 04

    Verified closeout

    Quality, records, cleanup, and unresolved items are visible.

We'll build the plan.
