- toe board;
- guard rail.
-
(a) Sketch a section through an independent scaffold and label the following members:
(b) list five stages involved in applying pebble dash finish to sandcrete
blockwork.
(c)State two reasons for sourcing capital for the operation of a building Materials venture.
Observation
Most candidates were able to:
- list five stages involved in applying pebble dash finish to a sandcrete blockwork;
- state two reasons for sourcing capital for the operation of a building materials venture.
However, few of them were unable to state one function each of base plate, toe board and guard rail parts of a tabular scaffold.
5 (a) Functions of parts of a scaffold
(i) Base plate: To provide a firm base for the standard.
( ii) Toe-board:
- To prevent the foot of workmen from slipping off the platform.
- To prevent materials from falling off the platform
- To prevent tools from falling off the platform
(iii) Guard rail: To prevent workmen from falling off the platform.
(b) Five stages involved in applying pebble dash
- get the materials, i.e pebbles and rendering mortar ready;
- prepare the wall surface, i.e cleaning, wetting or dampening;
- apply the rendering mortar (i.e., first and second coats);
- float and trowel the mortar for even surface;
- throw and press the pebbles into the rendered wall surface.
(c) Reasons for sourcing capital:
- for the expansion of the business;
- To meet customers’ demand
- To stabilize the business
- To increase profit margin.
