This book covers methods adopted for undertaking the design and construction of civil engineering projects. The options for separate design and construction are compared with design and build projects, construction management, and man­ agement contracting. The salient differences are shown between the various con­ ditions of contract used. The roles of the engineer, employer's project manager or his representative under different forms of contract are compared. Requirements for the production of contract documents, specifications, tendering procedures and choice of contractor are set out. The engineer's powers and the duties of his resident engineer on the site of con­ struction are considered in detail. Records, filing systems, programme and progress charts used by the resident engineer are illustrated, and advice is given on the handling of safety problems and difficult situations on site. Problems of measurement and billing of quantities according to the civil engi­ neering standard method are described. Correct procedures for setting rates for varied work, payment for method-related items, and handling claims for unfore­ seen conditions under ICE Clause 12 are given. Difficulties with delay claims and situations where the contractor submits quotations before undertaking varied work are discussed. The approach is essentially practical throughout and covers many actual prob­ lems met on site, including measures that are advisable in relation to site surveys and investigations, construction of earthworks and pipelines, and the production and placing of concrete.
