Most candidates were able to describe non-load bearing internal wall and the load bearing internal wall. 
However, many candidates failed to state correctly, the stages involved in fixing a door frame during the construction of a sandcrete blockwall.

The expected response to question 1 is as given below:
(a) Stages involved in fixing a door frame during the construction of a sandcrete blockwall are:
      (i) select the frame and check for squareness;
      (ii) fix galvanized metal fastenings or fixing lugs or large size nail to the back of the frame to match the block             courses;
      (iii) set the frame in position, plumb, level and brace it with struts;
      (iv) build the fastenings into the block joints;
      (v) check the alignment of the frame on the wall;
      (vi) lay courses of blockwork around the frame

(b) (i)    Non-load bearing internal wall:  This wall divides the internal
              space of the building and it supports it self-weight.
      (ii)   Load Bearing Internal Wall:  This wall acts as a vertical divider offloor space of a building and in doing so               accepts and transmit structural loads to its foundation.
