BS5837 vs BS3998 Part 2: How They Work Together on Real Sites

In Part 1 we covered what each standard is for. Part 2 is the practical bit: how they interact on real sites, and where projects go wrong.

A simple way to think about it

• BS5837 sets the construction context: surveys, constraints, protection, and what work is required.
• BS3998 sets the tree work quality: how pruning and removals should be specified and carried out.

Typical workflow on a construction project

1. Survey and categorisation: trees are assessed, constraints are mapped, and retention decisions are made.
2. Design and planning: root protection areas, construction exclusion zones, and protection measures are agreed.
3. Method statements and sequencing: what happens first, what must be protected, and what tree work is needed before breaking ground.
4. Delivery: any specified pruning or removals are carried out to BS3998; protection measures are installed and maintained.
5. Monitoring: checks during the works to prevent damage and keep the plan live.

Where projects usually go wrong

• Out of date surveys: desktop data that is years old, then everyone is surprised when the site does not match.
• Protection plans that never make it to site: good paperwork, poor delivery.
• Tree work specified vaguely: no clear specification, then quality and safety vary wildly.
• Programme pressure: tree work and protection get squeezed, then you pay for it later.

What good looks like

Good projects treat the standards as a joined up system: surveys are current, protection is installed properly, and tree work is specified and delivered to BS3998.
