PREFACE This check-list for site supervisors is issued by the Ministry of Works and Urban Development for use by Employers, Consultants and Contractors in order to ensure a uniform system of supervision of building construction projects and as a result ensure a safe and durable construction. It is to be of use mainly when construction works are carried out by contractors and can in some ways be of use for construction carried out by direct labour. In this check-list the responsibilities, liabilities and limitations of the supervisor are briefly mentioned. The steps to be followed in checking building construction works are expressed in general terms. Details of construction are specified in the drawings, technical specifications and in the general and special provisions of the contract. The duty of the site supervisor is to ensure that the construction works are executed in accordance with the contract requirements. Therefore in the application of this check-list the details specified in the contract document always precede before the application and use of it. There are also tables and forms in this check-list that help as records of the incidences affecting the work and as references. In addition the standard technical specification is used as reference on the preparation of this checklist.
