2 The input of materials, labour and machinery is based on realistic assessments. DAR (Electrical) 2012 contains most of the items of Analysis of Rates (Electrical) 2007. The analysis of many items have been modified and prepared based on rates of labour and material collected during November 2012 in Delhi. In order to arrive rates of work for a specific location and at a particular time, it is desirable to analyse the rates based on prevailing rates of material and labour. The Delhi Analysis of Rates (Electrical) 2012 will help all Engineers of CPWD, other Govt. Departments, Public Undertakings and consultants who follow CPWD Schedule of Rates in their works in analysing rates of works at different locations.

3 I acknowledge the hard wok put in by Sh. Mittal, SE(E) S&S and Sh. Singh, EE(E) S&S under the guidance of Sh. Jain, ADG (NR), Sh. Singhal, CE(E) NDR and Sh. Mukesh Vij, CE(E) DR, without which it would not have been possible to prepare Analysis of Rates (Electrical) - 2012. I also acknowledge the valuable suggestions of other members of specification committee involved in the process of preparation of Analysis of Rates (Electrical) 2012. I am sure that this Analysis of Rates will be useful to all concerned. iv PREFACE The Delhi Schedule of Rates (Electrical)-2012 which is the revised edition of combined Schedule of Rates for Electrical Works (Part-I) and Schedule of Rates for Electrical Works (Part-II) has already been approved and made effective from January 02, 2012.

4 The Schedule of Rates (Electrical) 2012 has also been uploaded on CPWD official webside. Accordingly Delhi Analysis of Rates (Electrical) 2012 is being published. The Delhi Analysis of Rates (Electrical) 2012 is a detailed document based on which Delhi Schedule of Rates (Electrical) 2012 is prepared. The rates of all items have been analysed based on rates of labour and materials collected from the market in Delhi during November 2011. Coefficient of labour and materials have been adopted based on previous Analysis of Rates (Electrical) 2007. However, a few changes have been made considering technological development, use of latest tools & plants and availability of skilled labour. All efforts have been made to ensure the correctness of the Delhi Analysis of Rate (Electrical) 2012.
