DRAFT CONSTRUCTION MANAGEMENT PLAN (CMP)) ON SHACKLEFORD MUSHROOMS, SHACKLEFORD ROAD, SHACKLEFORD, SURREY. 1.0 INTRODUCTION

1.1 Terms of reference

1.1.1 JNP Group was commissioned to undertake a Construction Management Plan (CMP) for the proposed redevelopment of Shackleford Mushrooms, Shackleford Road, Godalming, Surrey. This CMP has been written by the JNP Group with advice and input from the Applicant and other members of the Project Team.

1.1.2 The CMP describes the proposed programme of the construction works and the key

activities that will be undertaken. The construction activities comprises of demolition and site clearance of the existing site, alteration of existing access points onto Shackleford Road and Pepper Harrow Road, onsite infrastructure works and the construction of 18 new dwellings. It then identifies, in general terms, potential significant environmental effects associated with the activities and outlines the proposals for the mitigation of them. Detailed consideration of effects during construction and proposed mitigation measures are provided in each associated report submitted with the planning application.

1.1.3 The CMP forms part of the overall Project Management and as such, activities described

would be integrated with other Quality, Sustainability and Health and Safety management processes.

1.1.4 The Site Topographical survey is shown in Appendix A

1.1.5 The Site Layout is shown in Appendix B

1.2 Programme of Works

1.2.1 The construction programme will span approximately 20 months and the phasing

programme is outlined in Table 1.1

The programme can be divided into the following main stages:

• Enabling works; • Site preparation; • Site access and associated highway works; • Construction of the substructure; • Construction of the superstructure; and: • Fit out;

1.2.2 The Table 1.1 below summarises the main activities to be undertaken and the

approximate duration of the works.

5 months

Superstructure (phases of construction of building above ground level)

11 months

1.3 Description of the Works

1.3.1 The initial phase of the development will involve works to the highway at Shackleford

Road. Associated enabling works will involve possible relocation of services, groundworks at the site entrance, and forming the visibility splays at the site entrance.

1.3.2 Other preliminary works will involve the construction of the site attenuation facilities for

the surface water drainage, associated protection measures to the nature area and retained trees, and construction of main network of site infrastructure.

1.3.3 In the substructure construction work, excavations for foundations will be related to the

duration described in Table 1.1. It is anticipated that, due to the nature of the made ground and underground tanks, and the need to avoid damage to tree roots, that piling of some foundations may be required. The nature and extent of the piling is to be determined, but the operational procedures, hours of working and related matters are covered in the Code of Construction Practice (see below). Other foundations will be strip footings.

1.3.4 It is anticipated that within initial enabling works and site preparation it will include the

construction of a sales centre complex, with the site compounds and temporary working accommodation sited within the area to be identified for the final phase of the development.

Mitigation of Potential Effects during Construction

Procedures and Code of Construction Practice

1.4.7 The following measures will be pursued to eliminate, reduce or offset the potential adverse environmental effects identified in Table 1.3. Any detrimental or potential adverse effects will be approximately mitigated through a variety of procedures and actions that are set out in this report and in the identified mitigation measures for construction activities set out in individual reports carried out for the benefit of this site.

• Preparation of procedures which will clearly set out the methods of managing

environmental issues for all involved with the construction works, including supply chain management;

• Requirement to comply with these procedures included as part of the contract

conditions for each element of the work. All contractors tendering for work will be required to demonstrate that their proposals can comply with the procedures, and current best practice techniques;

• Establishing a dedicated point of contact and responsibility to deal with issues if

they arise. The point of contact will be a named representative from the construction manager or contractor, part of the professional team (the Construction Liaison Officer, see below);

• Production of a regular newsletter to be circulated to neighbouring occupiers, local

residents and the relevant authorities; and • Regular dialogue with Waverley Borough Council, Surrey County Council, the

Parish Council, and the local community.

1.4.8 The procedures will be set out in the Code of Construction Practice and circulated to Waverley Borough Council, the Parish Council and other relevant bodies, prior to commencement of the works. It will include the following:

• The broad plan of the phasing of the works and its context within the whole project; • Baseline levels for noise and dust and details of any monitoring protocols

that may be necessary during the works; • Housekeeping procedures and environmental control measures; Any requirement

for monitoring and record keeping; • Contact details during normal working hours and emergency details outside working

hours; • Provision for reporting, public liaison, and prior notification; • The mechanism for local residents and other members of the public to register

complaints and the procedures for responding to complaints;

Shackleford Mushroom Farm S81408 Flood Risk Assessment RevB

August 2009

• Prohibited or restricted operations (location or hours.); • Details of construction operations highlighting any operations likely to result in

disturbance and/or working hours outside the core working period, with an indication of the expected duration of key phases and dates;

The details of proposed routes for heavy goods vehicles travelling to and from the application site, and details of all works involving interference (where necessary) with a public highway, including temporary carriageway/footpath closures, realignment and diversions. 1.4.9 Further details on key issues are provided in the rest of this report.

Management of Sub-Contractors

1.4.10 Individual contracts (for example for groundworks and site preparation) will

incorporate relevant requirements in respect of environmental control, based largely on the standard of 'good working practice' as well as Statutory Requirements. Potential sub-contractors will be required to demonstrate how they will achieve best practice, how targets will be met and how potential effects will be minimised.

1.4.11 The following will be put in place to assist the management of sub-contractors:

• a Health and Safety Management Plan (HASMP), setting out the construction methodology and relevant legislation, guidelines and best practice;

• a Code of Construction Practice (CCP), which is intended to establish a framework

for the environmental aspects of the HASMP. This document will apply to all construction work, building site activities, cleaning and maintenance, transportation of materials and spoil, landscaping activities, and includes both preventative and mitigation measures;

• a Construction Management form of procurement for the construction of all new

buildings.

Management of Construction Works

1.4.12 There will be a designated liaison officer (the 'Construction Liaison Officer') who will be in regular contact with the public, will keep residents informed of progress and will deal with complaints and enquiries. This nominated individual will be named at the application site entrance, with a contact number, and will be identified to Waverley Borough Council, the Parish Council and to Surrey County Council and local resident/community groups, prior to the start of site activities, and whenever a change of responsibility occurs.

Response to Complaints

1.4.13 Any complaints will be logged on site and, where necessary, reported to the relevant

individual within the Local Planning Authority (and vice versa) as soon as practicable. 1.4.14 The procedures will specify the roles and responsibilities of the Construction Liaison

Officer and the Local Planning Authority in respect of breaches and complaints from the

Shackleford Mushroom Farm S81408 Flood Risk Assessment RevB

August 2009

public. The required actions will be different in each specific case, depending on the operation, equipment or location or applying additional controls (for example screening).

Prior Notice of specific activities or operations

1.4.15 In the event of unusual or specific activities and operations that can be anticipated,

(e.g. special large scale delivery of materials outside normal working hours) such events will be notified to Waverley Borough Council, the Parish Council, Surrey County Council, and to the relevant property owners or occupiers wherever possible and neighbours, in advance of the activity. The relevant ‘notifiable’ activities will be determined by agreement with the Local Planning Authority once the detailed programme of construction is defined and will include:

• Commencement of construction in certain areas; • Necessary night time, weekend or evening working (outside core areas) of a type

which may affect properties; • Road or footpath closures/diversions and movements of wide loads; and • Work on roads affecting land used by others.

Traffic Management (other than specific proposals for Access Roads)

1.4.16 Closures and Diversions - whilst no long-term road closures are envisaged, short term

closures may be required in order to deliver large items of building plant or equipment, or for works to the highway. If this is required then consent will be obtained from the Borough Council and County Council as highway authority.

1.4.17 Notice regarding possible short term closure or diversion of public rights of

way within and/or adjacent to the application site shall be given by the Contractor/Construction Manager to the relevant local authorities and to the emergency services in advance of the required closure or diversion dates.

1.4.18 HGV access will be from the Eastern end of the site on Shackleford Road, where the

main site access is to be located. There will be specific areas for construction compounds, designated off loading points, access gates, and security barriers.

1.4.19 All construction traffic entering and leaving the application site will be closely

controlled. Vehicles making deliveries to the application site or removing spoil or other material, will travel via designated routes. All HGV movements to and from the site are proposed to be routed along Shackleford Road to the A3 road. Signs will be placed at the site, and on surrounding roads, to inform drivers that other routes are not available to construction traffic. The proposed designated route will be subject to the agreement of the Borough Council and the County Council as Highway Authority.

1.4.20 Deliveries will be phased and controlled on a 'just in time' basis, all being clearly

marked to show their destination. This will minimise travel time around the application site and any associated noise. All transportation to and from the application site will be on rubber tyred vehicles. Tracked vehicles will only operate within the site. The timing of deliveries will seek to avoid the periods of peak traffic flows on the local road network.

Shackleford Mushroom Farm S81408 Flood Risk Assessment RevB

August 2009

1.4.21 It is anticipated that a workforce of approximately 50-60 people will be employed, working for the main contractor, sub contractors, suppliers and other organisations. Cars and other vehicles used by workers will be parked within the site. Restrictions on parking on neighbouring roads will be strictly enforced. The Code of Construction Practice will identify the location of the site compound, temporary accommodation, parking areas for site workers, areas for the loading/unloading of delivery vehicles and haul routes within the site.

1.4.22 Traffic movements for construction vehicles are estimated as follows:- Workers cars, Vans, etc. Up to 100 movements per day HGV deliveries Up to 10 movements per day Monitoring and environmental management of the works

1.4.23 An assessment of the potential effects of the construction activities on perceived noise

levels and on air quality is set out in Noise and Vibration Report, and Air Quality Report.

1.4.24 The following summarises the mitigation measures to be adopted in relation to noise, vibration and air quality issues:

• Designated and supervised areas and compounds for storage of materials, storage

of plant and equipment, site huts and parking of vehicles, storage of building materials, and locations for loading and unloading of vehicles.

• Agreed construction methodology to minimise generation of noise, vibration and

dust;

• Use of hoardings, where appropriate, to assist acoustic screening;

• Requirement for engines to be switched off on-site when not in use, use of quieter plant, noise suppression equipment, regular plant maintenance, screening of plant (if appropriate);

• Spraying of spoil heaps, excavated material and other areas with water when

conditions dictate;

• Effective wheel/body washing facilities to be provided and used as necessary;

• A road sweeper will be used as and when the need for road cleaning arises;

• Vehicles carrying waste material off-site to be sheeted;

• Restriction on the use of fires on site.

Waste Management, Recycling and Disposal 1.4.25 Wates Group is committed to promoting waste minimisation and encouraging

beneficial reuse and recycling. Strategic targets have been set for waste reductions across Wates, leading to zero non-hazardous waste being sent to landfill by 2010. The strategic statement ‘Target:Zero’ as well as the Group Waste Management Policy is included in the Site Waste Management Plan. Additional strategic statements; Timber Procurement Policy, Environmental Purchasing Policy, Group Environmental Policy and Group Energy Management and Carbon Policy are also included in the Site Waste Management Plan.

1.4.26 Waste will be generated during all stages of the construction works. Major

sources of waste within the construction process are:

• Packaging – plastics, pallets, expanded foams etc; • Waste materials generated from inaccurate ordering, poor usage, badly stored

materials, poor handling, spillage etc; and • Dirty water, for example from silt.

1.4.27 All relevant contractors will be required to investigate opportunities to minimise waste

arisings at source and, where such waste generation is unavoidable, to maximise the recycling and reuse potential of construction materials. Wherever feasible, such arisings will be dealt with in a manner that reduces environmental impact and maximises potential re-use of materials. Recycling of materials will largely take place off-site where noise and dust are less likely to have an effect on the surrounding area to the application site.

1.4.28 The destination of all waste or other materials removed from site will be

notified by the Contractor/Construction Manager for approval (via consultation with the Authorities). Loads will only be deposited at authorised waste treatment and disposal sites. Deposition will be in accordance with the requirements of the Environment Agency, the Environmental Protection Act 1990, Controlled Waste Regulations 1992, Controlled Waste (Amendment) Regulations 1993, the Special Waste Regulations 1996 and Special Waste (Amendment) Regulations 1996 and 1997, the Duty of Care Regulations 1991, the Landfill Regulations 2002 and the Landfill (Amendment) Regulations 2004, Hazardous Waste Regulations 2005 and List of Waste Regulations 2005.

1.4.29 To prove the correct depositing of excavated material and to prevent the

occurrence of fly-tipping, a docket system will be used. The Contractor/Sub-contractor will operate a sequentially numbered docket system, to confirm that each load is received at the approved disposal site. Copies of the dockets are to be provided to the nominated manager, and available for inspection at the application site. In addition, direct routes via main roads to designated tips will be agreed with the sub contractors. No burning of construction waste will be undertaken on the application site.

1.4.30 The assessment of potential effects of the proposed development on water resources

is presented in the Flood Risk and Drainage Strategy and Hydrogeology/Geology respectively. The protection of trees, vegetation and ecological resources are set out in Landscape and Visualisation study, Arboriculture and tree survey report and the Ecology reports.

1.5 Summary

1.5.1 The construction programme will span approximately 18 months, and it is envisaged that the development will be completed in two main phases.

1.5.2 The initial phase of development will involve works to the accesses. Associated

enabling and infrastructure works will be followed by the construction of the 25 dwellings. The sequence of development will be from the Shackleford Road.

1.5.3 Plant and equipment to be used during construction has been identified, and it is likely

that there may be piling of some of the foundations due to depth of made ground and underground obstructions. The noise and vibration and air quality implications of plant and construction activities have been assessed in the Noise and Vibration Reports and in the Air Quality Report.

1.5.4 Potential effects arising from construction activities have been identified and mitigation

measures are identified in this CMP report and in other relevant reports submitted to support the planning application. A Code of Construction Practice will be prepared and submitted, and circulated to the Borough Council, Parish Council and other relevant organisations to set out the agreed procedures and ‘best practice’ on construction operations, and in accordance with relevant legislative requirements. Likely significant adverse effects will be appropriately mitigated.

1.5.5 Management of subcontractors will be through procurement procedures and an

agreed commitment to the Code of Construction Practice. A designated liaison officer will be in regular contact with the public, will keep residents informed of all relevant matters, and will deal with complaints and inquiries. Monitoring of construction activities will be reported back to the local authority on a regular basis.

1.5.6 The comments stated above are based on information received from other consultees,

and this report is based upon the recommendations stated within these reports. This report is intended for the use of the developer of the site in support of their planning application for the site only.
