Constructing Environments ENVS10003 Semester 2 2014 A01-Logbook Week 9: Detailing Strategies 2 Studio Report: This week is the campus lab. Sidney Myer Asia Centre:
Softwood is used and the colour will change to grey (Cyprus). Zinc is also used in ribs in order to allow the sheets to be able to take both tension and compression. Corroding will happen if there is no coating applied on them. In Situ columns is used and faces the same challenge with the zinc standing ribs. It may corrode. These columns are made to support and hold the whole building. They hold up the loads from the ceilings to the floor and that is the reason why they are very huge.
The materials that are most commonly used in this building for construction is Zinc. Even though it is more expensive but from a design prospective, with the time pass, the colour changed but it will be in the same colour as cooper.
Slabs with decorative concrete are used but if they polish, they may crack. There are some horizontal capping beams with silicone and vertical transom. Aluminium is the material for making the glazing system and it helps to reflect the heat. Like black panels, some of the parts are separated into different tiny pieces for many different benefits such as easy to install and move. For the bricks that used in the walls, they may have some water damage to the bricks by considering there is pipe nearby. If the damage is continuing it will results in bad consequences. Stress will applied to the bricks and they will crack in the end.
Since some parts of the building will not get enough sunlight, colors will change due to this and even become mould that is color turns to green. Water damage is another reason of getting mould since there are water downpipes nearby and rainfalls. There is not enough sunshine so when the material becomes wet, it is hard to dry properly and the mould occurs. It is an important issue that need to be considered when design and construct buildings. Concrete cancer can be seen in this building as well. Main reason for the occurring of concrete cancer is poor workmanship and the only way to fix it is to paint the wall in order to cover or just move the wall away. It important to avoid any water interactions in the constructing process. Water causes the expansion of steel rods so the concrete flake off and the concrete cancer occurred. Precast concrete sunshades are also used in this building. The problem is that they look like they are going to sag. Natural forces play an important role in the sagging of the sunshades. There are forces applied to them especially the gravity force. Also, these sunshades are very long and the spanning of the length is not very effectively. It is better to use less this material in the future construction processes.
Learning Loop Construction Detailing: if the impact is not considered at detailing stage, it can be very big. Soils expanding and contracting is what construction detailing dealt with. Some examples like the expansion, contraction and movement joints etc.
Health and Safety: it is mainly about helping people in a dangerous situations such as fire. Some examples are building code limits the material selection and balustrades required to fit certain standards and heights.
Cleanable surfaces and maintenance access: It is to avoid corners that trapped dirt. For wet areas, carpet is not a good choice. In some commercial buildings, there are some suspended ceilings with hidden services.
Composite Materials: There are both monolithic material and composite materials. For Monolithic materials, they are single materials and the combined materials which the components are hard to see or indistinguishable like the metal alloys. The Composite materials are 2 or more materials that are combined but with individual material can be distinguished.
Repairable surfaces and resistance to damage: it is how easily a material is repaired. For instance, plaster board is very easy to fix. Skirting can prevent quick damage from feet and also covers caps between floor and wall. Aging gracefully: it is about to choose materials and coat them to a suitable area. It deteriorate quickly in harsh environments such as seaside and polluted area. Materials that can improve with age are cooper (goes green) and timber ( goes grey).
Glossary:
Bending: is the shaping of sheet metal by straining the metal around a straight axis. A bending operation compresses the interior side of the bend and stretches the exterior side. For example, flanging, hemming and seaming are all bending operations.
Cornice: it is an exterior ornamental trim at the meeting of the roof and wall. Cornice usually includes a bed moulding, a soffit, a fascia and a crown moulding.
Shadow Line Joint: is one of the easiest way to trick the eye is to have a shadow joint in the end of the edge where boards joined together. The shadow line is where two surfaces meet. A small gap is placed in between and is used in ease construction.
Composite Beam: is a beam combing different materials to work as single unit. Structural steel, precast concrete and cast-in-place concrete are good examples of it.
