You can send the plans and the wording you have received. We will confirm what information is needed before you instruct.

What this service is for

Professional attendance at the construction stages that matter

Supervision is used where the approved method needs an arboriculturist to inspect, brief, witness or record particular operations. The aim is to keep the agreed tree-protection strategy intact when real site conditions are encountered.

Supervision is used when the tree-protection strategy depends on certain construction stages being inspected or witnessed by an arboriculturist. It is normally focused on specific hold points, not continuous presence on site.

The consultant can brief the site team, inspect protective measures, attend sensitive excavation or service work and record what happened. This gives the client an auditable trail and helps the contractor deal with unexpected site conditions without improvising around retained trees.

The best time to arrange supervision is before the relevant work is programmed. If we receive the condition, AMS, TPP and site programme, we can identify the attendance points and make sure the project team knows when to call.

What you receive

The exact output depends on the site and project stage, but the work should always be clear, coordinated and usable by the people making the next decision.

Pre-start arboricultural site briefing
Inspection of fencing and ground protection
Supervision of specified works within or close to RPAs
Photographic and written site records
Liaison notes where tree officer involvement is required
Completion or condition-discharge evidence where within scope

The finished information should be easy for the client and design team to understand, technically defensible for the Local Planning Authority and practical enough to carry forward into the next project stage.

What matters technically

The details that make the document useful.

The strongest arboricultural documents are not generic. They connect the tree information to the live drawings, explain the points that matter and leave as little room as possible for contradictory interpretation.

Pre-start briefing

A short site briefing can make the approved tree-protection requirements much clearer to the people actually carrying out the work.

Protection inspection

Fencing and ground protection can be checked before sensitive operations begin.

Supervised operations

Excavation, surfacing, service installation or other work close to roots can be attended where the approved method requires it.

Records

Dated notes and photographs provide an auditable record of the tree-related compliance activity.

How it fits into the wider BS5837 process

Supervision is where the approved tree strategy meets the reality of a live site.

The AMS and TPP should identify the operations and areas that need control. Supervision then checks or witnesses the relevant stages while the work is happening.

If unexpected conditions arise, the arboricultural implications can be considered and recorded before a quick site decision creates a larger compliance issue.

Before you request a quote

Send whatever project information you already have.

You do not need to build a perfect technical brief. Start with the site address, the current drawings and the exact wording from the council, tree officer, architect, engineer or Building Control team. If a previous arboricultural report exists, include it. If the design has been revised, send the latest revision.

Send the condition, AMS, TPP and construction programme. If the contractor already knows the proposed dates for sensitive work, include them so attendance can be planned.

If there is a planning submission, condition-discharge or construction deadline, include that date as well. Programme matters because some services depend on a site visit, drawing information or an earlier BS5837 stage being complete.

We would rather tell you that a document is not needed than sell the wrong one. The aim is to identify the information that unlocks the next real project decision.

Where clients normally need this

Typical project situations

Typical triggers include excavation within or close to RPAs, service installation, specialist surfacing, removal of existing hardstanding and planning conditions requiring an arboricultural watching brief.

Pre-start tree-protection inspection

The planning condition requires fencing or ground protection to be checked before commencement.

Excavation near roots

The method requires hand digging, root inspection or arboricultural attendance at a sensitive stage.

Specialist installation

Surfacing, foundations or services close to retained trees require a controlled method and recorded attendance.

Condition compliance record

The client needs evidence that the approved arboricultural measures were implemented.

After instruction

What happens once you go ahead.

The exact sequence changes by service, but the working principle is the same: review the live project, complete the technical work, keep the drawings coordinated and issue information that has a clear purpose.

Project review

We check the current drawings, authority wording and any previous arboricultural information. This establishes what is already known and prevents the new work being prepared in isolation.

Site work where required

Survey-based services include the relevant site inspection and measurements. Later-stage documents may rely primarily on approved information, current construction detail and targeted site context.

Technical coordination

The Arboricultural Supervision is prepared against the project information that actually matters to the decision. Drawing references and tree numbers should remain clear throughout.

Issue and next step

You receive the finished information for the project team. Where another BS5837 stage follows later, the report should make that obvious rather than leaving the client to guess what happens next.

Where the design changes materially after issue, send the revised drawing. We can check whether the document remains applicable or whether a focused amendment is required. Keeping the technical information aligned is far easier than explaining inconsistent documents after submission.

A useful report is more than a compliance exercise

It should help somebody make a decision.

A technically correct document can still be difficult to use if it is vague, disconnected from the drawings or written without the next project stage in mind. Good arboricultural work should reduce uncertainty rather than add another layer of terminology.

For the client, that means understanding what has been found and what it means for the project. For the architect, it means tree information that can be coordinated with the design. For the planning authority, it means a clear evidence trail. For the contractor, it means protection and construction requirements that can actually be followed on site.

We also distinguish between what is important now and what belongs later. There is little value in preparing construction-stage detail while the planning layout is still changing, just as there is little value in repeating feasibility discussion once a pre-commencement condition is the only thing stopping the build.

Keep the project moving

Tell us what decision is waiting.

If the application cannot be validated, send the validation request. If the tree officer has asked a question, send the full response. If a planning condition is preventing commencement, send the decision notice and approved drawings. If the engineer needs foundation-related tree data, send the Building Control request.

The fastest way to get the right answer is to show us the real blockage. From there, the Arboricultural Supervision can be considered in the context of what the project needs to achieve next.

What good looks like

Supervision should solve site questions quickly and leave a clear record behind.

The point is not to create unnecessary visits. Attendance should be tied to the real risks and the requirements of the approved documents or planning condition.

Good communication with the contractor is essential. The person carrying out the excavation needs to know the restriction before the bucket goes into the ground.

Keep the report and drawings on the same revision.

A surprisingly common problem is a technically competent report that refers to an old layout. If the footprint, access, levels, drainage, services or surfacing change, send the revision. We can then confirm whether the arboricultural information still stands or whether a targeted update is required.

That becomes even more important once the project reaches construction. The contractor needs documents that reflect what was approved and what is actually going to be built. Clear, coordinated information is easier for everybody: client, architect, planning officer, tree officer and site team.

Who we work with

Clear information for the whole project team.

Homeowners: you do not need to arrive with a technical brief. Send the council wording and drawings you have. We will explain what the request means and what information is needed next.

Architects and planning consultants: we can work directly from the live design information and keep the arboricultural documents tied to the correct revision. That is especially useful where the proposal is changing and tree constraints need to be considered as part of the design rather than after it.

Developers: consistent tree references and a clear document sequence make it easier to carry the same evidence from feasibility through planning and into construction.

Contractors: once permission is in place, the language needs to become practical. Protection zones, excavation methods, access restrictions and hold points should be obvious enough to use on site.

Tell us what you already have.

If somebody has already surveyed the trees, send the report. If the council has already accepted part of the arboricultural package, send the approved documents. If the architect has revised the scheme, send the new drawing as well as the old report.

Existing work is useful context. It helps us avoid repeating information unnecessarily and makes it easier to see where the project has genuinely changed.

If you are starting from scratch, that is fine too. An address and current plan are enough to begin the conversation, and the original council or consultant wording is the best guide where a formal request has already been made.

Questions clients ask us

Arboricultural Supervision FAQs

These are general answers. If you have project-specific wording, send it with the drawings and we can tell you how it applies to your site.

How many supervision visits are needed?

It depends on the planning condition, AMS and construction sequence. Visits are normally linked to specific hold points or higher-risk operations.

Can you brief the contractor?

Yes. Pre-start briefings can be an important part of turning the approved tree-protection strategy into practical site instructions.

Do you provide records?

Site attendance normally produces a written and/or photographic record appropriate to the condition and work undertaken.

What if unexpected roots are found?

The work can be reviewed before roots are cut or disturbed so an appropriate response can be agreed and recorded.

When should I book supervision?

Before the sensitive activity is programmed where possible, particularly if the planning condition specifies attendance or approval at a particular stage.

Ready to move it forward?

Book the arboricultural attendance before the sensitive work is programmed.

Send the approved documents and site programme so the required visits can be identified.
