- Draw, to a scale of 1 : 100, the:
(i) floor plan;
(ii)front elevation.
(iii)Draw to a scale of 1:50, a sectional view on X – X. Indicate any 4 specifications on the section.
[Assume suitable dimensions where necessary]
Observation
Candidates were asked to draw the floor plan, front elevation and sectional view on plane X – X. Most of the candidates attempted this question and their performance was okay. However, some of the candidates could not draw correctly the specified roof in both the front elevation and the sectional view.
Candidates were expected to do the following:v
FLOOR PLAN
(i) draw to scale 1:100 (18,000 x 13,500 ± 10);
(ii) draw the walls;
(iii) draw the cutting plane X – X;
(iv) draw the windows (20 in number);
(v) draw the doors (18 in number);
(vi) draw the beams (6 in number);
(vii) draw the columns (2 in number);
(viii) label the partitions (16 in number);
(ix) write floor plan and scale;
(x) draw neatly.
FRONT ELEVATION
(i) draw to scale 1:100 (18,000 x 13,500 ± 10);
(ii) draw the ground;
(iii) draw the finished line;
(iv) draw the living room floor line;
(v) draw the four vertical lines;
(vi) draw the beams (horizontal line);
(vii) draw the columns with circular base and top;
(viii) draw six conventional windows;
(ix) draw the double door;
(x) draw the concrete roof;
(xi) draw the eaves projection;
(xii) write front elevation and scale;
(xiii) draw neatly.
SECTIONAL VIEW ON X – X
(i) draw to scale 1:100 (18,000 x 13,500 ± 10);
(ii) draw two foundation footings;
(iii) draw earth filling, hardcore, concrete slab and the screed;
(iv) draw the ground line from the base of the foundation;
(v) draw the cut edge;
(vi) draw two walls in section;
(vii) draw two walls in elevation;
(viii) draw the finished floor in dining area;
(ix) draw beams (two in number);
(x) draw one door in section;
(xi) draw one lintel;
- draw one column with circular base and top;
- draw two windows in elevation;
- draw reinforced concrete;
- draw roof cover (bituminous felt);
- indicate four specifications;
(xvii) write section x – x and scale;
- draw neatly.
