FOREWORD

The Proclamation to define the powers and duties of the Federal and Regional Executive

organs of the Federal Democratic republic of Ethiopia No. 4/1995 empowers the Ministry of

Works & Urban Development to prepare the Country's Building Code, issue Standards and

Guidelines for design and construction works, registration of professionals and consultants and

follow up and supervise the implementation of same.

In exercising these powers and in discharging of its responsibilities, the Ministry is issuing a

series of Building Code Standards, Manuals and Guidelines of general application.

The purpose of these documents is to serve as nationally recognized documents, the application

of which is deemed to ensure compliance of constructions with the minimum requirements for

design, procurement procedures, construction and quality of materials set down by the

Ministry.

The major benefits to be gained in applying these documents are the harmonization of

professional practice and the ensuring of appropriate levels of safety, health and economy with

due consideration of the objective conditions and needs of the country.

As the documents are technical documents which, by their very nature, require periodic

updating, revised editions will be issued by the Ministry from time to time as appropriate.

The Ministry welcomes comments and suggestions on all aspect of the documents. All

feedback received will be carefully reviewed by professional experts in the field with a view to

possible incorporation of amendments in the future editions.

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 check-

list.
