=27.2.01 MODULE UNIT DESCRIPTION= This module unit involves construction of buildings and related building works form foundations, walls, roofs, finishes and demolitions works.

PURPOSE
The module is designed to equip the trainee with knowledge, skills and attitudes necessary to enable the trainee to work in a workshop or in a construction site.

SPECIAL REQUIREMENTS
The trainee should have basic knowledge in Technical/building drawing and skills in use of tools and equipment used in building trades as well as building materials.
