How Arborists Actually Work: Tree Surveys, Risk Assessments & Sectional Dismantling Explained

Professional tree surgery is far more than cutting branches or removing trees. Every project involves a structured process built around safety, planning, technical expertise and compliance with industry standards such as BS 3998. At TD Tree & Land Services Ltd, our approach combines consultancy, risk assessment, specialist equipment, and highly trained arborists to deliver safe, efficient outcomes across domestic, commercial, and public-sector projects.

This guide explains how arborists actually work, from the initial survey through to climbing, rigging and controlled dismantling in complex environments.

Stage 1: Tree Survey & Initial Assessment

Every project begins with a detailed inspection. This ensures the correct approach is chosen based on tree condition, location and surrounding constraints.

Tree species identification and condition assessment
Structural defects such as decay, cavities or weak unions
Proximity to buildings, roads, utilities or public areas
Environmental constraints including protected species or habitats
Access requirements for machinery and equipment

Our tree surveys and consultancy services provide detailed reports for homeowners, developers and local authorities, including BS 5837 planning surveys and safety assessments.

Stage 2: Risk Assessment & RAMS Documentation

Before any physical work begins, arborists complete a full risk assessment and produce RAMS (Risk Assessment Method Statements). This ensures all hazards are identified and controlled.

Key considerations include:

Falling timber and controlled drop zones
Public safety near roads, footpaths and properties
Use of chainsaws at height
Weather conditions such as wind or ice
Emergency rescue planning

All work is carried out in line with Safe Systems in Procurement (SSiP) protocols and industry best practice, ensuring compliance across public and commercial projects.

Stage 3: Choosing the Right Removal Method

The approach to tree work depends on available space and risk level:

Straight felling – Used in open areas where a tree can safely fall in one direction
Sectional dismantling – Used in confined spaces where the tree must be removed piece by piece
Crane-assisted dismantling – Used for large or hazardous trees near structures

Stage 4: Climbing & Access Techniques

In most urban and confined environments, arborists climb trees using rope and harness systems rather than relying on machinery. This allows precise positioning and controlled work at height.

Rope access systems for safe ascent and movement
Harnesses and anchor points for stability
Secondary safety lines for redundancy
Communication between climber and ground crew

This method ensures minimal impact on surrounding structures, gardens and landscapes while maintaining full control over each stage of the work.

Stage 5: Rigging & Controlled Cutting

When removing sections of a tree in confined areas, rigging systems are used to control how branches and timber are lowered to the ground.

Rigging involves:

Attaching ropes and pulleys to secure sections before cutting
Using friction devices to control descent speed
Lowering branches safely into designated zones
Preventing damage to buildings, vehicles or landscaping

This process requires precise coordination between climbers and ground teams to ensure safe and efficient operations.

Stage 6: Sectional Dismantling Explained

Sectional dismantling is the most common method used in residential and urban environments. Instead of felling a tree in one piece, it is dismantled in controlled sections from the top down.

The process typically follows these steps:

Climber ascends and secures anchor points
Outer branches are removed first
Large limbs are cut and lowered using rigging systems
The main stem is removed in sections
The remaining stump is processed separately

This approach ensures maximum control and safety, particularly when working near buildings, roads or public areas. Our storm damage team frequently uses this method to safely remove unstable trees.

Stage 7: Ground Operations & Site Management

While the climber works at height, the ground team plays a critical role in maintaining safety and efficiency.

Managing rigging ropes and lowering systems
Processing branches into manageable sections
Feeding material into woodchippers
Maintaining clear and safe working zones
Monitoring safety throughout the operation

This coordinated approach ensures work progresses smoothly while maintaining high safety standards.

Stage 8: Stump Removal & Site Clearance

After the tree is removed, the remaining stump can be addressed depending on client requirements.

Stump grinding below ground level
Full stump removal where required
Preparation for replanting or construction

Stage 9: Waste Management & Sustainability

All material generated during tree work is processed responsibly.

Woodchip used for landscaping or biomass
Timber recycled into firewood
Habitat creation where appropriate
Minimal waste sent to landfill

Our sustainable firewood offering ensures valuable timber is repurposed efficiently.

Why Professional Arborists Follow a Structured Process

Tree work involves significant risk if carried out incorrectly. A structured approach ensures:

Safety for workers, clients and the public
Compliance with UK regulations and standards
Protection of surrounding property and infrastructure
Long-term health and management of retained trees
