LOGBOOK ENTRY Week 1! Luke Adamson!
CLASSROOM ACTIVITY SITE VISIT! This week, instead of participating in a class tutorial, we had a site visit to the new extension of the Royal Melbourne Hospital. This is a unique construction as it is being completed on top of an existing structure, while the areas below are still being used by patients.! Below are some notes taken after a tour of the site by Don from Grocon PCL.!

The build started 2 years ago and is expected to be a 4 year project with an overall budget of 120 million dollars.! The crane loses a lot of operation time. This is because the hospital is still operational so the helicopter pad needs to be accessed. While that is happening the crane must be shut down.!
! ! The operating theatres had to be kept going through construction.! ! ! -
-
A new lift core had to be constructed through 3 floors and into the basement. There was 26 piles driven into the ground for foundation.!
! ! There was still a live plant area servicing the hospital! ! ! -

The build would be shorter if it was a new build rather than an extension.!
The tower crane is anchored down 2 floors below.!

! -
They only fire sprayed the primary steel members to give it a 2 hour fire rating. The secondary members aren't sprayed to save money.!
!
! -
Beams on levels 4 were put in above the right level. They are going to be moved down once the area is water tight so they can removed the existing roof structure. Moving the beams will be done with a pulley system.!
! ! Connection between different levels.! ! ! -

Level 6 will consist of office space and an ICU ward. The significance of this floor is that it is the first flooring that could be poured as one slab.!
This area will have hi tech switch glass walls, which means they can be translucent or clouded depending on what is needed. !
! ! All the patient rooms must have natural lighting.! ! ! -
-
! ! -
!
The hallways have lower heights because they have to contain all the wire and cables above.!
The ICU area was much more expensive to build due to its unique glass walls.!
! -
! -
This floor also has a terrace area to promote health and wellbeing and filter natural light.! The facade will be comprised of panels made off site in a factory.!

There are some holes cut through steel beams for pipes and services. These can not be cut anywhere, so an engineer must determine where they can be put and at what size.!
This structure used steel columns 2 stories high rather than 1, for efficiency reasons.!
! ! This construction must pass earthquake ratings! ! ! The top story is the plant area, where all the ducts and services will be kept.! ! ! ! ! ! ! ! -

These are images of a site visited on the way to the Grocon Site. Recent works were the creation of the capping beams on top of the soldier pier support walls. We were also advised that some of the walls had just been sprayed with shotcrete.

E-LEARNING & READINGS ! For water or heat to penetrate there must be the following 3 things:! - An opening.! - Water or heat.! - A force that will move the heat or water.! To stop the movement of either of these, only of the 3 items above needs be removed!
! Openings can be planned or unplanned! ! Ways to conserve heat! - thermal insulation! - thermal breaks (like double gazing)! - air leakage!
!
Rubber comes in natural or synthetic and are commonly used for seals, flooring, insulation and hosing.!
!
Plastics come in thermoplastics (mouldable when heated) thermosetting plastics (only able to be moulded once) and elastomers (like silicone).!
!
Paints can be oil or water based.! ! THIS WEEKS KEY TERMS GLOSSARY! Down pipe- a pipe to carry rainwater from a roof to a drain or to ground level.! Flashing- a strip of metal used to stop water penetrating the junction of a roof with another surface.! Insulation- material used to insulate something.! Sealant- material used for sealing something so as to make it airtight or watertight.! Vapour Barrier- any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture! Gutter- a shallow trough fixed beneath the edge of a roof for carrying off rainwater.! Parapet- a low protective wall along the edge of a roof, bridge, or balcony.
