MINISTRY OF WORKS AND TRANSPORT

STANDARD SPECIFICATIONS

December 2012

FOREWORD

The mission of the Ministry of Works and Transport (MoWT) is to promote an adequate, safe and well maintained works and transport infrastructure and services so as to effectively contribute to the socio-economic development of the country.

In exercising this mission and in discharging its responsibilities, the Ministry is issuing a series of Design Manuals, Guidelines, Codes and Standards, of which the “Standard Specifications for Building Works” is one part thereof.

The Standard Specifications for Building Works will be a nationally recognized document which will serve as a standard reference for the preparation of specifications for works to be undertaken on building construction projects.

The major benefits to be gained in applying this document are the harmonization of professional practice in the building construction in Uganda and curtailment of informal developments so as to ensure well-planned, well-maintained, safe, cost effective and decent building developments and human settlements throughout the country.

The Standard Specifications will be periodically updated and new editions issued to cater for the dynamic technological developments in the construction industry.
