About this book

Written for the owners or managers of small construction businesses, the ROMAR handbook and workbook provide both the management and technical advice needed in order to make a success of routine maintenance and regravelling as a business activity. The handbook and workbook can be used together by reading the chapter in the handbook and then working through the examples in the workbook. The first part of the books deals with the principles and include the following: a summary of technical considerations and engineering standards for earth and gravel roads, and introduction to choosing appropriate road construction and maintenance technology, soil mechanics, equipment and the major operations in a typical labour-based road project using a case study of one of the most successful labour-based road programmes in Africa. The second part looks at putting those principles into practice - how roads deterioate and how to manage maintenance contracts, how to carry out regravelling projects, pricing and bidding for road maintenance contracts and how to build up detailed prices for a bill of quantities. With particular reference to labour-based projects, advice is included on how to manage people, covering team building, communication, training, motivation, incentives and how to ensure good discipline and morale.
