1 HOW YOU NEED TO PLAN AND PREPARE FOR A SUCCESSFUL DEMOLITION PROJECT GUIDANCE BRIEF FOR CLIENTS & ADMINSTRATORS CONSTRUCTION (DESIGN & MANAGEMENT) REGULATIONS 2007 This document has been produced to guide and assist with you with the important aspects of planning, managing or administering a demolition activity in conformance with the statutory requirements of the Construction (Design & Management) Regulations 2007 (CDM). The primary goal is to provide a summary of the key activities to aid in avoiding common project oversights and errors that ultimately lead to cost variations and / or project delays. The key aim of CDM 2007 is to integrate health and safety into the management of the project and to encourage everyone involved to work together to: (a) Improve the planning and management of projects from the very start (b) Identify hazards early on so that they can be eliminated or reduced (c) Target effort where it can do most good in terms of health and safety This useful high level document has been structured to proactively highlight the specific stages of the operational process as the project unfolds in an effort to aid clients and administrators to successfully plan and prepare. It is expected that sitespecific needs not addressed within this guide will be administered at suitably identified stages within the overall process. March 2011 Special Note: This is a guidance document only; it is important that you take your own independent advice with respect to any contract into which you propose to enter.

2 THE RIGHT INFORMATION FOR THE RIGHT PEOPLE AT THE RIGHT TIME INTRODUCTION The Dorton Group has compiled this brief planning and preparations considerations document based on our comprehensive and extensive industry experience which has shown on many occasions that clients, when faced with a demolition project, could potentially improve the eventual outcome. It has been structured in a way as to aid clients, whether managing the project directly or indirectly through an appointed subcontractor, as it covers the key areas in a logical order to aid better coordination of the various logistical needs and provide a more detailed understanding of the wider aspects and impacts associated with this type of operation in line with some of the legal requirements under CDM regulations. The Dorton Group takes a strategic view towards the way that is approaches deconstruction projects as it considers demolition to be a profession not just a process. The concept being that through careful planning and preparation projects can be executed right first time every time by reducing delays, enabling more reliable costing s and completion dates and by improving communications between key parties. The contents of this guide represent the collective views of the highly experienced team at the Dorton Group which also include Institute of Demolition Engineers 2010 President Terry Quarmby. ESTABLISHING RESPONSIBILITES, DUTIES AND ROLES INITIAL STAGES 1. PLANNING OF PROJECT - CLIENT The following is a list of key activities that we would advise clients consider during the initial planning phase of the project with a view to minimising and negating potential projects delay risks: Carry out feasibility study taking into account key areas such as cost effectiveness, potential disruptions to existing operations, logistics etc. Implement detailed surveys, i.e. Asbestos (We would recommend you appoint a UKAS accredited person for the analysis of samples) Structural / dilapidations etc. Ground conditions Services Local environment aspect/impact Access & egress constraints Provision of adequate resources and time in terms of coordination and communication with prospective contractors. Notification/planning consents, for example F10 and section 80 Note: These stages will invariably be repeated by the appointed Principal Contractor

3 At this stage we believe it is important to advise that the decisions that you will ultimately make regarding providing project information and the selection and appointment of competent project advisers, designers and contractors will be key to not only achieving a safe and successful project but also to manage the required legal duties and criminal liabilities. 2. APPOINTMENT OF KEY STAKEHOLDERS There are three key stakeholders appointed by the Client in a CDM regulated project. The following detail highlights what Dorton Group considers being the key responsibilities and requirements from each and should be used for guidance purposes only: CDM Coordinator Knowledge, training and industry experience. Production of adequate and suitable information specific to the project etc. Identification of significant hazards Liaison with consulting/informative contacts. Early appointment Initial notifications Production of Health & Safety File Principal Contractor Provision of adequate resources Knowledge, training and industry experience Production of Health & Safety Plan COSHH assessments Liaison with authorities Compilation of relevant information & documents Control of sub-contractors Notifications/applications Creation of project teams Designer Product knowledge Knowledge training and industry experience PROJECT STAGES 1. Management of the Project These are the high level responsibilities that Dorton Group suggest be carried out in a logical sequence from the inception of the project to successful completion. Decide on scope of works Surveys asbestos, services, contamination and structural Appointment of CDM Coordinator, Designer and Contractor Develop plan Implementation of plan Site set up Progress meetings Project safety meetings

4 Audits & inspections Corrective actions Waste management Recycling, reclamation Liaison with authorities Meet client expectations Meet contract conditions Hand over 2. Management of Subcontractors If you appoint subcontractors to operate on your site these are some of the key points to discuss and plan: Service diversions etc Health & Safety & Environmental implications Personnel management Subcontractor methodology to consider Audit & inspection Scaffolding & plant 3. Liaison with others Prior to and during the project here is a list of potential bodies that both you and or your appointed contractor will need to liaise with regard to arrangements, permits etc. to ensure that you avoid project delays and conform to required regulations and responsibilities: The local authority Health & Safety Executive Environment agency Police The public Emergency services British Waterways Rail network Service providers Waste management Consultative bodies PROJECT PLANNING & IMPLEMENTATION STAGES Throughout all stages of the demolition process there are actions, which must be implemented and clearly defined. The timing of these actions is often dictated by the pace of the works or the safety, environment and contract conditions that exist. Formulating a checklist of possible needs or requirements will help to plan such actions and eliminate or reduce reactive fire fighting processes that make the management of projects stressful and difficult. Legally under CDM there is a requirement for competent persons to plan all demolition works and to produce a written method statement and risk assessment.

5 Listed below are examples of such actions, and although they are not to be regarded as exhaustive they show interdependence on each other and good practice. Access & Egress Security Emergency Procedures Please be aware that the following points should be considered to ensure that you are able to meet the requirements of CDM.. Clearly defined site boundaries, preferably by utilizations of existing walls and fencing and or by secondary use of solid or anti-climb heras fencing or hoarding etc. Out of normal working hour s security. Lockable gateways of sufficient width to allow ease of access and egress by large vehicles or plant Alternative traffic and pedestrian routes to retained areas of the site other than access from shared routes, wherever practical and possible. Re-routing of emergency access or escape routes where traditional routes have crossed the demolition areas. (In extreme cases this can mean the erection of covered walkways, fixing of temporary stairwells, arrangements with adjacent property holders etc) Asbestos-Other Survey Information - Contaminated Materials-Waste It is also important to note the following legal requirements which will ultimately help you to reduce the potential for additional cost and minimise possible time delays. A fully intrusive Refurbishment and Demolition asbestos survey should be undertaken in all demolition areas. HSE strongly suggest the use of a UKAS accredited survey organisation. If access is not possible or restricted then this should be drawn to the attention of all parties. Please note that Pre Demolition Asbestos Surveys are now a statutory requirement under CDM where demolition and major refurbishment projects are to be carried out (Please refer to HSG264) Please Note: no waiver against the 14-day notice can be granted where further asbestos is discovered during the demolition phase due to the absence of the correct survey. Asbestos registers and details of previous asbestos removal etc. will need to be made available prior to present occupier decamping Contact details of works engineers familiar with all aspects and locations of asbestos, contaminated materials, oils, fuels, waste areas etc. Structural surveys and if necessary intrusive investigation will need to be carried out by the Client if there are any doubts as to the method of the existing construction

6 You will need to provide Registers, drawings and or details of all contaminated areas, vessels, pipes and containers etc. Provide details of types and hazards arising from such contaminated areas, products or materials. Provide details of any previous or intended decommissioning, purging, cleaning, testing and certification of safety etc. or par thereof Provide details of any heavy, light or partial contamination of site areas below and above ground Provide details of statutory or commercial implications concerning the removal, handling and disposal of any such contaminated products and or materials either stored for use or as a by-product of the works. Any projects with a value above 300,000 are required to have a Site Waste Management Plan which will detail waste segregation methods and how much waste is produced, recycled and sent to landfill. Services-Utilities-Waterways Should any of the following be part of the project site then appropriate considerations would need to be made during the planning and implementation stages to ensure the necessary arrangements and resources are scheduled to prevent project delays. Details to include locations of all services, data cables etc., entering, leaving or crossing the site. Services to mean, Electricity, Gas, Water, Sewerage, Telecommunications (it would also be of productive assistance to provide details of all works engineers etc. having concern or responsibility for services, maintenance and repair to the above elements and to implement internal or external re-directions or cut offs to the site particularly where there appears to be a sharing of supplies to adjacent areas, cost and time being of paramount concern). Details of all services sub-stations within the site boundary and whether they are to be retained and protected or decommissioned and demolished. Details of any services directly feeding retained area from within or crossing the demolition site boundary (where such conditions exist it is strongly recommended that re-direction of such supplies is sought prior to demolition). Details of or intention of notice to Gas. Electricity, Water, vendor/shipper/meter owner etc. of termination/disconnection of services at the boundary of the site. Note: electricity and gas can take 8 weeks from initial notification to cut off. Details of any way leaves or other arrangements to maintain and retain service supplies to adjacent or opposite areas. Locations of utility service runs below and above ground, depth of services and whether they are to be removed as part of the demolition site clearance works, re-directed and or re-laid elsewhere.

7 Utility services to mean Mains Water, Foul Water, Storm Water, Electricity, Gas Data Services, heating Systems, fuel Lines, Internal Communications Etc. Details of requirements or arrangements with the Environment Agency, British Waterways or other interest bodies for works near to or abutting rivers or canals, i.e. discharge points and water take off points concerning the removal of any pipes, pumps or other structural impediments. Also public access. Statutory and Public Notices Local Environment Once again as part of the planning and implementation stages please ensure that you consider the implications of any of the following as by overlooking them during the early stages could lead to considerable delays once the project is underway. The details and timing of statutory notices, e.g. asbestos removal ASB5 to be submitted a minimum of 14 days notice to the Health and Safety Executive prior to the commencement of removal works. Section 80 notice of demolition of a structure, to local authority building control department, (many councils invoke a 6 week rule). Registering of site with the environment agency for removal of hazardous materials, (it should be noted that many hazardous waste landfill sites require at least 72 hours notice; prior to delivery of waste from site) Utility services notice (beware of possible 12 week delay in implementing request). Any party wall agreements, if any, with retained sections of the structure adjacent to occupied areas. Note: (the finalisation and agreement with party wall surveyors etc. can be a prolonged and frustrating exercise. It is strongly recommended that where such agreements are required that the necessary matters are initiated at the earliest opportunity). Details of any current or expected objections to the proposed development where delay to the commencement of the demolition works may affect the programme. The requirements for the demolition contractor to address public concerns over the proposed demolition works. Note: most demolition contractors should be able to allay any public fears regarding demolition activities, by attending public meetings to explain how issues such as noise, dust and damage etc. can be addressed and reduced to the lowest possible expectations through careful and deliberate planning prior to execution. In the past this has proved to be an invaluable tool for developers. Many Brownfield sites, particularly those that may have lain idle for some time, have been adopted for habitat by wildlife. Where such wildlife are protected, i.e. in the case of bats, badgers, newts and birds etc., projected start dates may need to be revised and all parties advised of any constraints. GUIDANCE The detail contained within this guidance is varied with many of the topics seemingly intertwined or running concurrently with others.
