  • Work planning 1 Revision03
  • Describe methods of undertaking electrical installations systems and components. Work planning Aims and objectives of this session To be able to know how to plan jobs. • To know why planning is important
  •  Before starting any installation an assessment of the site needs to be done. Risk assessment, safe storage, access to PPE and suitable access equipment for the installation needs to be taken into account before starting work. It is important to be able to communicate and have good working relationships with many different people. Tools and equipment needs to be checked and stored safely and securely. Isolation procedures and equipment is a key component to working safely.
  • Work Planning Creating a work plan may seem to be a waste of time. A little thinking ahead at the beginning of an installation could save time, trouble, man- hours and cost later on.Any plan must have a purpose.Putting down a statement of purpose or the aim, is always a good start.The design of the system is a good idea to tackle next.This may be your own design or given to you from the office.From this you can deal with the specifications. This will enable you to calculate the quantitiesof materials, time etc.Don’t forget to leave time for site clearance and waste disposal.Commissioning should be considered.Once the drawings and plans are ready the plan can be implemented.Efficient use of resources of labour and equipment is vital.
  • Plan detailDesign of the systems.This is done in consultation with the client and carried out in the office.Calculations are performed with appropriate able sizes and types chosen along with wiringsystems and accessories. Ideally, consultations will take place with the architect and otherparties who affect the choice of wiring system and positioning of accessories and equipment.From these designs a specification is created detailing with cable types, accessories, ratings ofprotective devices etc.This specification is then allied to the drawings to ensure that positions are correct and don’tconflict with other trades.We can’t have a socket behind a radiator for example
  • Plan implementationThere are a number of elements here. Adequate plant and equipment to be on site when work is to start with an appropriate lockup. Appropriate PPE is ready for use from the start. Specifications and drawings are available for use.Once the drawings and specification are ready then the efficient use of resources of labour andequipment becomes the dominant factor.We cannot have people stood around waiting for cables simply because we weren’t able to getthings ready.To this end a chart may become useful. Good planning will also enable the sub-contractor to maximise profits and minimise time lost due to wasted productivity.
  • Bar ChartA chart such as a Gantt chart helps visualise who and what should be where and when.
  • Bar Chart
  • ToolsWhen work is about to start we also must ensure that a list of necessary power tools ismadeThe plant required may be short or long list but will include at least the following:power drills conduit bending machine and vicetransformers cable tray machinehand lamps circular sawdrill bits and cutters stocks and diessteps. cutting greasescaffolding. water levelladders These lists are in addition to the initial assessment of the cables, clips, plugs, fixings, conduit, tray etc. that will also be needed.
  • PPEWhen we come to dealing with Personal Protective Equipment (PPE) the plan will need to detailthe equipment necessary for the work involved as we did with the plant and equipment. ThePPE list will cover the requirements of at least the following: boots overalls hard hats goggles.There may be additional needs for: face masks knee covers – in case of having to kneel raincoats reflective over covers gloves.
  • PlanningMonitoringAll plans are subject to alteration .Things may have to be altered as deliveries are delayed or people get sick etc.So plans change and monitoring is the process whereby we ensure that the overall aim is kept inview.CommissioningThe final element of the plan is the commissioning of the installation.The testing process is set out in Guidance Note 31, and covers all the inspection and testingrequirements for an electrical installation.We must ensure that when the work is finished it is safe for the client to use and some detailshould be provided about the nature of the tests and how the results are to be recorded.This may simply be set out as:‘All inspection and testing shall be carried out in accordance with the guidance provided by theIEE and recorded on the test sheets provided’.
