How does the information in your drawing set compare to what you observed at site last week?

The drawing set effectively showed the structural systems of the building, and the different angles/ elevations/sections showed the building in multiple dimensions and settings. The drawing sets also gave a good indication of how the building would Mit into it’s immediate surroundings. However, it didn’t really show how the building would look in the greater surroundings, and in context with the existing large structures in the area.

The drawing set also does not show how the materials would work together, and what the Minal aesthetic of the pavilion would be. Something that I observed on site that did not really translate in the drawing set, was the use of colour on the Minal building.

How does the scale of the building compare to the scale of the drawings?

The drawings, especially the different elevations and sections do a good job of showing the scale of the building. It is interesting to see the building in real life though, and see how different sized elements work together on site. The picture above is a good example of this, as it shows how different structural components with different heights and forms work together, and how their scale affects the overall aesthetic of the building.

Something that you don’t get in the drawings also, is the speciMic sizes of elements that exist on site. For example, the changing size of steps that lead to the main deck, or the size of the timber pieces used in the canopy at the front of the building.

How do the architectural and structural drawings differ?

The architectural drawings in the drawing set focus on design and function of the building and the rooms within the building. It shows names of rooms, area of rooms, pathways, plants, seating and footpaths. The architectural drawings provide readers with a a basic image of layout and form. The architectural drawings include small scale drawings of the building and its surroundings.

The structural drawings are much more speciMic and detailed. They show materials, joints, structural elements and systems as well as some service systems. The structural elements focus more on the building/construction of the building. As opposed to the architectural drawings, structural drawings are often large scale, as to show details about speciMic construction systems.

WK4 – Learning Loop Span – distance measured between 2 structural supports (vertical/horizontal)

Spacing – repeating distance between series of similar elements. Associated with supporting elements, and measured from center line to center line of supporting elements.

Beam – horizontal structural element.

Carries loads along length of beams to the vertical supports. Can be supported at both ends, at numerous points along beam, at points away from beam and at one end of the beam.

Cantilever – created when structural element is only supported at one end.

Carries loads along length of member to the supports.

Floor systems > Concrete slab Various types used to span between structural supports. > Steel Mlooring Various forms with some utilizing heavy gauge structural steel and others using light gauge steel framing. Sometimes is combined with concrete slab systems. > Timber Mloorboards Uses combination of bearers(primary beams) and joists (secondary beams).

Joints Construction joints – panel/elemental nature of precast mean that joints naturally occur where one precast element meets another.

Structural joints – type/performance join precast to other parts of building.

Joints greatly depend on desired aesthetic outcome.

Concrete is artiMicial stone. Made of cement mixed with water. Sand + gravel forms hard solid material. à 1 part cement : 2 parts Mine aggregate : 4 parts coarse aggregates : 0.4-­‐0.5 parts water.

Concrete is Mluid before it hardens and can be shaped. à Formwork – temporary support/mold used to hold liquid concrete until it hardens.

Concrete can be laid in situ or pre cast.

Concrete is strong in compressions but weak in tension (steel reinforcement i m p r o v e s s t r u c t u r a l p e r f o r m a n c e = reinforced concrete).

In Situ Concrete that has been poured into formwork and cured on a building site.

Generally used for structural purposes. à footings, retaining walls and non standard structural elements.

Shotcrete – concrete that is sprayed rather than poured.

Pre Cast Concrete element that has been fabricated in controlled environment and then transported for installation on site.

Many applications, often associated with structure. à Rarely used in footings. Common in retaining walls, walls and columns.

WK4 GLOSSARY

Joints – Used to divide construction into manageable sections of work. Joints connect these sections and are potential weak points.

Control joints – required to absorb expansions/contractions due to variation.

Steel decking – An element of some Mloor and roof systems. A sheet of proMiled steel decking which is laid down and then covered with a concrete slab or covered with timber decking. Provides Mlexibility in concrete slabs.

Bearer – Primary beams of a construction system. Usually supports joists which are laid across the bearer. (Timber construction) Girder – A large iron/steel beam used for building bridges and building frameworks. Similar to bearer.

Concrete Plank – Sheet of concrete that when laid together creates a solid base/roof structure.

Spacing – Repeating distance between a series of similar elements. Associated with supporting elements.
