General

This Arboricultural Method Statement (AMS) is prepared on behalf of Mr and Mrs N Conway

for the proposed two-storey side extension, rear single-storey extension to link the garage to

dwelling and replacement of rear flat roof area to pitched roof at Eccles Barn Whitehough,

Chinley. The AMS is required by Section 7.1.3 BS 5837:2012 Trees In Relation To Design,

Demolition and Construction – Recommendations, as construction activities are occurring in

the Construction Exclusion Zone and therefore cannot be addressed by a Heads of Terms

document. The Planning Permission HPK/2014/0030 has two arboricultural planning

conditions:

3. (a) No development or other operations shall commence on site until a scheme (herein after

called the approved protection scheme) which provides for the retention and protection of

trees, shrubs and hedges growing on or adjacent to the site, including trees which are the

subject of any Tree Preservation Order currently in force, has been submitted to and approved

in writing by the Local Planning Authority. No development or other operations shall take place

except in complete accordance with the approved protection scheme.

(b) No operations shall commence on site in connection with the development hereby

approved (including demolition works, soil moving, temporary access construction and / or

widening or any operations involving the use of motorised vehicles or construction machinery)

until the protection works required by the approved protection scheme are in place.

(c) No excavations for services, storage of materials or machinery, parking of vehicles, deposit

or excavation of soil or rubble, lighting of fires or disposal of liquids shall take place within any

area designated as being fenced off or otherwise protected in the approved protection scheme.

(d) Protective fencing shall be retained intact for the full duration of the development hereby

approved and shall not be removed or repositioned without the prior written approval of the

Local Planning Authority.[sic]

4. No trees, shrubs or hedges within the site which are shown as being retained on the

approved plans shall be felled, uprooted, wilfully damaged or destroyed, cut back in any way or

removed without the prior written consent of the Local Planning Authority. Any trees, shrubs or

hedges removed without such consent, or which die or become severely damaged or seriously

diseased with five years from the completion of the development hereby permitted shall be

replaced with trees, shrubs or hedge plants of similar size and species unless the Local

Planning Authority gives written consent to any variation.[sic]

Eccles Barn Arboricultural Method Statement

4 This document is intended to demonstrate the degree of protection to be undertaken and

demonstrate the fact that, in arboricultural terms, the development is sustainable.

This AMS sets out proposed measures to minimise and mitigate construction impact on the

trees and targets for the management of the site during the construction phase. It is

intended that the AMS remains under review during the construction of the project.

Sequencing of tree protection measures has been programmed with the contractors

construction programme. The following text contains a series of considerations that Mr and

Mrs Conway and their appointed developer will follow whilst working on the project to

completion.

1. Timing of Works

The timing of the primary works involved for the construction of the two-storey side

extension, rear single-storey extension to link the garage to dwelling and replacement

of rear flat roof area to pitched roof, which will have an impact on trees, are listed

below. These timings are approximate and are influenced by a number of factors.

All the tree works and fencing requirements will be undertaken prior to ground works.

The critical Arboricultural Operations in relation to the Construction Programme are

outlined below.

Date Job Description

Week 1 Erect of Type A Construction Exclusion Zone Fencing – commence

excavations.

TBA Re-locate fencing for scaffolding, install temporary working area

Targets

• Tree work to be undertaken by qualified contractors only to BS 3998:2010.

• The stumps of trees to be removed by grinding.

• Type A Fencing to be installed as detailed prior to all other works.

• Fencing to be re-located under supervision.

• Appointment of an Arboricultural Clerk of Works to liaise with the Arboricultural

Consultant (AC).

2. Construction Exclusion Zone Fencing

Adequate protection of trees requires the installation of the correct fencing type at

the locations shown on the Tree Retention and Protection Layout Drawing – 3024_102.

Targets

• Type A Heras fencing erected on a metal framework as indicated on the Plan

3024_102.

• Fencing installed at locations shown on the plan.

• Location and adequacy signed off by Arboricultural Clerk of Works and LPA

and advised AC.

• Tool Box Talk – make construction staff aware of the importance of areas.

• Signs to be erected advising of the areas importance.

3. Site Offices/Welfare Facilities/Compound

Site offices, welfare facilities and a small compound will be required at the site due to

the length of the contract period. Site offices can be used in place of Construction

Exclusion Zone fencing to protect trees. Contamination of the Construction Exclusion

Zone is considered unlikely. However, the following issues should be considered.

Targets

• Site offices/welfare facilities, if used as tree protection, to be placed on pads.

• No discharge of effluent into Construction Exclusion Zone.

• Compound to be outside of Construction Exclusion Zone.

4. Temporary Working Area

It is proposed to adjust the location of the fencing to allow the erection of scaffolding

due to the pinch-point being created by the approved structure. The ground is to be

covered with ArborRaft and then the scaffold.

Targets

• The existing ground to be brought to level with sharp sand/geotextile base.

• ArborRaft to be placed over.

• Scaffold to be placed on top.

5. Services

As part of the development, services are required. These are not located in the

Construction Exclusion Zone. Therefore, there are no further issues in this respect.

6. General Precautions

The retention of trees requires a number of general precautions to be taken.

Compliance is to be maintained on site by the appointed Clerk of Works and visits by

the Arboricultural Consultant. The site visits are detailed at criterion 1 – Timing of

Works.

Targets

• Spoil from the foundation pits or other excavations shall not be placed within

the Construction Exclusion Zone. No materials, equipment, spoil or washout

water may be deposited, stored or parked within the Root Protection Area/

Construction Exclusion Zone.

• On-site inspections to be undertaken by the Arboricultural Clerk of Works with

the Arboricultural Consultant visiting during critical operations. The aim of the

Eccles Barn Arboricultural Method Statement

8 visits is to maintain on-going liaison with all personnel involved in the site

development, High Peak Borough Council and its Tree Officer.

• Any defects requiring rectification shall be notified to the Contractor/Site

Manager/Arboricultural Consultant and the client.

• A site logbook for tree protection measures is kept to record all stages of the

development from the erection of the protective fencing, right through to the

completion of the project. This will be made available to the Arboricultural

Consultant and High Peak Borough Council, if required, to show evidence of

continuous site monitoring.

Introduction

The ArborRaft has been developed by Permavoid Limited. Permavoid was successfully launched into the UK construction market in 2000 as a lightweight subbase replacement in engineered pavements.

The product has been developed over the last 14 years for various applications including stormwater attenuation and specialist drainage systems for podium decks, sports pitches and equestrian surfaces.

In 2003 the city of Amsterdam undertook a number of trial projects using Permavoid to improve the growing environment for trees in the urban realm.

the TreeBox High Performance (HP) and subsequently after the success of these trials, the ArborRaft system was tested and introduced into the tree planting and tree root protection sector.

The ArborRaft combines tree soil with a geocellular raft system to create growing space for newly planted and existing trees in hard landscapes and in areas subject to vehicle loadings.

The unique ArborRaft system spreads the load ensuring there is no compaction of the soils around the tree roots, maintaining the perfect environment for the trees to establish and mature

and cities.

Oxygen and water levels can be managed and improved within the ArborRaft system. All types of vehicle loadings can be accommodated, from cars through to Heavy goods vehicles.

The ArborRaft system prevents damage to the root structure from vertical pressures by completely absorbing all imposed loads placed upon it. This permits the root structure of new and existing trees to grow in a healthy environment.

The structural void created by the ArborRaftwith a nutrient rich soil to act as a slow release fertilizer continually feeding the root structure when combined within a porous paving construction.

The ArborRaft system can be incorporated into a development’s sustainable drainage design. The system has a 90% void ratio which may be used to store surface water

This water may be re-used if required as grey water or

environmental standards.

The ArborRaft system is a combination of specially matched and tested materials.

foundationsLightweight

The damage caused by tree roots lifting pavements and disturbing services is now eradicated by using the ArborRaft system. The root structure is provided with a healthy growing area which is left uncompacted and with access to water and constant nutrient feeding if required. Tree roots do not tend to break through pavement surfaces when their rooting environment is so similar to that of a natural

ArborRaft helps create a natural air barrier preventing roots from penetrating the surfaces.

parksEvents and

Large prestigious outdoor events require high quality, cost

temporary and permanent applications. ArborRaft is ideal for providing shallow sustainable drainage solutions for large areas that require constant use even in the most severe of weather events. This was evident during the London Olympics where 60,000m2 of Permavoid geocellular units were installed at the equestrian area and was removed and re-used after the games.

Intensive use of our green spaces and the need to provide more

parkland and trees. Areas of hard surfaces are often being laid to accommodate visitors and this can cause problems to the root systems of existing trees.

By using the ArborRaft system these footpaths can be created with minimal construction depths. The ArborRaft acts as the subbase and root protection system upon which the hard surface can be directly laid. There is no requirement for any granular materials and the geology of the soils around the trees can be left untouched.

The Permavoid system can also be used in basement construction for insulation and structure protection against the ingress of deep tree and plant rooting systems. The Permavoid creates a high strength structural air void that acts as the perfect barrier against the ingress of deep rooted tree and plant roots into below ground

By making use of the Permavoid, walls can be ventilated and underground hollow spaces are created. These also serve as a growth barrier for tree roots. As a result, cables, pipes and other underground facilities are protected.

The TreeBox HP (High Performance) system is the most successful modular system for planting new trees in hard landscapes. The system permits unlimited amounts of soil or tree sand to be planted in areas subjected to heavy and

geocellular units, pre cast concrete supports and a concrete roof to create the ultimate high strength tree planting pits for our towns and cities. For more information please refer to our Treebox HP brochure.
