INTRODUCTION This Construction Method Statement covers all civil works including construction of an Intake structure, Powerhouse, Pipeline, installation of Screens, Turbine and Tracks.  The proposed scheme will consist of an intake weir on the Connachie Burn at OS grid reference NH 37117 05327. A secondary weir will be located on the small tributary at approximately NH 37266 05220 which will divert additional flow through twin-walled gravity penstock and discharge behind the main weir. From the Intake Chamber the flow will be transported through pressurised penstock to the powerhouse approximately 1940m downstream (in terms of pipe-flow) at NH 37841 06826. Once the flow has passed through the turbine it will discharge into an un-named ephemeral drainage channel that flows directly into the River Tarff. The Scheme is a run-of-river type and the layout is illustrated in Drawing 3431-11-01 which includes the major project components. The electricity generated will be exported to the nearby 11kV grid that extends from Fort Augustus and currently supplies the Culachy Estate with mains electricity. The Scheme generally comprises the following, but not necessarily sequential, stages: ã   Construct site compounds and lay-down areas and other initial preparatory works; ã   Bring equipment onto site; ã   Initial construction works – construct access tracks; ã   Main construction works – construction of intake weir, pipeline, turbine house and tailrace; and ã   Reinstatement. The construction process will normally run over a period of 6-7 months, though much of the main construction operations would be achieved in a shorter period of approximately 4 months. 2. ROLES AND RESPONSIBILITIES  All parties will operate within the environmental constraints identified in the Environmental Report (ER), the Planning Conditions, CAR Licence Regulations and such other instructions as may be issued by any statutory body and approved by the Project Manager. The following outlines the roles and responsibilities of all persons involved in the project. 2.1. Project Manager  Responsibilities include liaison with client & designers during the design stage to ensure that all planning conditions are met. During construction, site visits will be scheduled according to specific project duties. The Project Manager will have overall responsibility for ensuring that the action of each party accords with their responsibilities and for implementing such corrective measures as may be needed. The Project Manager will ensure that any pollution incident is promptly reported to SEPA and other parties as agreed 2.2. CDM Co-ordinator The CDM Coordinator is appointed under Construction (Design and Management) Regulations 2007. He is responsible for preparation of pre-construction Information and the Health & Safety File. He gives advice on suitability of the contractors construction phase Plan. He delivers the Health & Safety File to client. The CDM Coordinator is not responsible for any aspect of design.
