Why use Scale? To represent a larger object on a small and practical size. To show proportions of a design in relevant size to each other (Eg.1:1 Screw, Bolts, Handles; 1:5 Structural Joist; 1:10 Walls; 1:100 The whole building).
• Symbolic Representations: Metal:
Brickwork:
Concrete Block:
Plywood:
Timber:

Floor and Framing Systems: Before scaffolding, it is to construct a next layer when slab is completed. Sheet steel goes in place for above the layer and reinforcement is ready to go in place once is set. Then concrete is poured in and vibrated to remove of any air bubbles.
•
Steel framing systems: have various forms with some using the heavy gauge structural steel members and others using the light members. The most common using forms are the combinations of both the heavy structural steel framing and the light structural steel framing members. Sometimes, the steel framing also combined with the concrete slab depends on the structural functions.
•
Timber Floor Framing Systems: uses a combination of bearers and joists which the bearers are the primary beams and the joists are the secondary beams. The spacing of the piers or stumps is determined by the span of the bearers. The spacing of the bears is the same as the span of the joists. Normally a floorboard span is 400 or 450 mm.
•
Concrete: For water adding: 1.Too little water, the mixture will be too
stiff and cannot work. 2. Too much water, the final mixture of concrete will not be strong enough to meet the requirements. Formwork is used to support and hold the liquid concrete temporarily until it becomes hard and strong enough.
•
In Situ Concrete: fabrication and assembly of the formwork, meet any requirements such as the reinforcement, vibration, the pouring and the curing of the concrete. It is used on footings, retaining walls and other non- standard structural elements.
•
Precast Concrete: It will not affect by climate so has the time efficient and need less labours on site. Mainly manufactured in factories and need to transport to site. Most common used in retaining walls, columns and walls.
Glossary •
Spanning: Distance that is measured between two structural supports. It is not always the identical lengths. It can be measured between vertical supports when considering horizontal members or horizontal supports when considering vertical members.
•
Spacing: Repeating distance between a series of similar elements and often associated with beams. It is generally measured from the centre-line to centre-line.
• •
Cantilever: It is created when a structural element that is support at only one end. The function is to carry the loads along the lengths of the member and transfer these loads to support. It can be horizontal,vertical and angled.
