LOGBOOK ENTRY Week 4! Luke Adamson!
!
Band beams go against the conventional beam as band beams are wide and shallow. The main reasoning behind this is to save space, especially in multi-storey developments where there could be potential to create extra floors with the space saved.!
!
Hot rolled steel is steel in a semi molten state that is put through rollers and transformed into various shapes.! ! In construction there is primary, secondary and tertiary systems.!
!
It is easier to put the primary supports so that they span the shortest distance because that is the part taking the most weight and doing the most work.!
!
It is quicker to have secondary members perpendicular to primary members, these tend to be cold formed.!
!
Cold-formed steel goods are created by the working of sheet steel using stamping, rolling, or presses to deform the sheet into a usable product.!
! Since cold-formed steel members are formed at room temperature, the material becomes harder and stronger. Its lightweight makes it easier and more economical to mass-produce, transport and install.

CLASSROOM ACTIVITY ! OVAL PAVILION CASE STUDY TEST! Title Block! List the types of information found in the title block on the floor plan page.! Consultants, Key Plan, Client, Project, Description, Title, Drawing Number, North direction.! Why might this information be important?! In order to let everyone know the contents of the drawing and keep people accountable.!
Drawing Content- Plans! What type of information is shown in this floor plan?! Scale, Rooms, Materials, Dimensions, Key materials.! Provide an example of the dimensions as they appear on this floor plan? What units are used for the dimensions?!
! ! ! !
Is there a grid? What system is used for identifying the grid lines?! Yes. North South lines have numbers, East West lines have letters.! What is the purpose of the legend?! To be able to identify the key components of the drawing.! Why are some parts of the drawing annotated? Illustrate how the annotations are associated with the relevant part of the drawing.! Some parts of the drawings are annotated to clarify specific details.!
! !
Illustrate how references to other drawings are shown on the plan. What do these symbols mean?!
!
These symbols show the drawing number and the direction that the drawing is showing.!
! !
2
How are windows and doors identified? Provide an example of each. Is there a rationale to their numbering? What do these numbers mean? Can you find the answer somewhere in the drawings?! Doors and windows are identified by their room numbers and door and window respectively. These numbers refer to their number and the room they are leaving.!
!
Illustrate how floor levels are noted on the plan! Are some areas of the drawing clouded? Why?! Yes. This is so you can identify changes.!
! !
Drawing Content- Elevations! What type of information is shown in this elevation? How does it differ from the information show on the plan?! Height and Materials, the Design of the building, the Facade, Floor Levels.! Are dimensions shown? If so, how do they differ from the dimensions on the plan? Provide an example of the dimensions as they relate to the elevation.! Yes. They are less complex and only relate to key areas, but are referenced the same in both drawings.! What types of levels are shown on the elevations? Illustrate how levels are shown in relation to the elevation.! The floor, ceiling and reduced level are all shown.!
! ! !
Is there a gird? If so, how/ where is it shown?! There is no grid.! What type of information on the elevations are expressed using words? Illustrate how this is done.! Only annotation about material is shown (i.e ‘frameless glass’, ‘double glazed doors’).!
! ! ! !
Illustrate how the doors and windows are identified on the elevations.!
!

! Drawing Content- Sections! What type of information is shown in this section? How does it differ from the information shown on the plan and elevation?! The sections show different rooms, above and below ground, internal materials and some of the structure, including wall thickness.! Illustrate how the section drawing differentiates between building elements that are cut through and those that are shown in elevation.! Elements cut through are show with heavier lines.!
!
Provide examples of how different materials are shown on the sections.!
! ! ! ! !
! ! Drawing Content- Details!
What sort of things are detailed?! Joints, Foundations, Smaller details like fall on a surface.! Are the details compressed using break lines? Why?! Yes. Break lines are used to indicate that a portion of the drawing isn't show.! Provide examples of how different materials are shown on drawings at this scale.!

E-LEARNING & READINGS ! Concrete is strong in compression, weak in tension, so steel is added for reinforcement in tension.! Hardness- high! Fragility- low! Ductility- very low! Flexibility- low!
! It is cost effective, has high embodied energy but lasts a long time! !
In Situ Concrete is any concrete poured and cured on site. It is very labour intensive and gives time constraints.!
!
Shotcrete is a sticky concrete applied to walls like retaining walls with a high pressure hose.!
!
Pre Cast Concrete is fabricated in a controlled environment and is common in walls, retaining walls and columns. It is useful to use because it saves time needed to be on site, is cheaper and can be better controlled quality wise.!
!
Foundations are the lowest division of a building, partly or fully underground.!

THIS WEEKS KEY TERMS GLOSSARY! Joist- a length of timber or steel supporting part of the structure of a building, typically arranged in parallel series to support a floor or ceiling.! Girder- a large iron or steel beam or compound structure used for building bridges and the framework of large buildings.! Concrete Plank- a plank made out of concrete! Bearer- a member that supports some of the load of a structure.! Spacing- the distance between like members
