- TYPE II-A--Protected Non-

Combustible – roof, floor

- In between two buildings ERC& Doug McDonell

- The price of the material, and the

transport method of the material <-

size is bigger than the main entrance,

so the other ways of transporting

materials are needed.

- spanning

2_MSLE BUILDING (LINK BETWEEN BUILDINGS)

Potential construction constraints_ The price of the material, and the transport method of the material,

time commitment

Links to other buildings_ Sharing wall with the neighbouring building

Construction type_ type 1 building, steel, concrete…Type 3 building, non combustible exterior wall, low

fire separation system, no spacing between building/ Refurbishment?

Structural System(s)_ structural system, exterior closure: doors and windows, superstructure: floor

construction

Materials_

Other relevant comments_

Cantilevered beam support at only one end. A series of cantilivers forms a long span system. Long span steel +

pre-stressed concrete to form a storey. Floor system, wall system

Zinc used in the exterior wall, brick wall rubber floor and rubber coating on the bottom

side of the wall <- protect the wall, stainless steel -> holding glass,

3_QUEENS COLLEGE EXTENTION

Potential construction constraints_ The price of the material, and the transport method of the material

into the site, time

Construction type_ type 1 building

Structural System(s)_ structural system, wall system, services(plumbing)

Materials_ Pre-casst Concrete, steel framing, brass, steel, box gutter, glass window and door, plastic

4_ORMOND THEOLOGY CENTRE RECEPTION

Potential construction constraints_ The price of the material, and the transport method of the material

Links to other buildings_ near zoology building

Construction type_ type 5 buildings- interior wall

Structural System(s)_ exterior closure- wall & door system, mechanical- plumbing system’ interior

finishes

Materials_ PVC pipe, Bluestone floor, glass wall, aluminium door frame, glass for sliding door, concrete

wall (by moulding), copper exterior wall

Other relevant comments_ glass wall <- penetrate too much light to the information desk, & too hot

Historic reason, keeping part

*Reinforced Concrete,

structural wall element,

(pouring concrete- moulding,

can shape in any way)

-Base, Slab, (foundation &

footings- )

Concrete- water, sand,

aggregate

*Steel bar for reinforced

concrete

Drain- plastic tube,

collect moisture

Traditional timber wall frame

(Wall system)

- Refurbishment of this site

Cladding -

Aluminium

tented roof

*Steel bar for reinforced concrete

-(For foundation and footings)

* Bar Guards

- end caps act as protective device Site preparation-

Gravel- mix of

small rock

Acrylic coating

on the gravel

maybe used for

protection -flat

roof.

Finish Nail vs Brad Nail- Finish

nails are for fastening larger crown

and baseboard trim, brad nails are

used to install smaller trim to help

prevent splitting and to promote a

cleaner looking job with less touch-up

work after the nailing is done.

5_DESCRIPTION/DEFINITION OF THE FOLLOWING KEY

CONCEPTS

Span_ is the distance between vertical supports. Cross Section_ is a surface which is shown by a cut through of an object, usually right angel to an axis.

Bending occurs quickly when

concentrated load applies on the

bridge

Deflection and crush occur when keep

adding the force, (loaded to heavy) on

it. <- Tensile force exceeds its

allowable loading capacity.

-The screw weaken the strength of

the timber, so the crack is formed

surrounding the screw.

The middle pinewood is the only load

bearing wood, which means the other

two and the plywood have no

function in this case. Thus, load is only

carried and concentrated on the

middle pinewood

Strength_ is the power of an object to resist stress/ force, or a capacity of bearing load. Compression_ is a force that push the particles of the object compact together and resulting in the shortening of the object. Tension_ is an external loads that pull on an object and elongate the material. Flexion_ The condition of being flexed or bent. Shear_ is an effect that is developed from action of opposite forces which results in shifting of horizontal and vertical parallel planes of an object. -> Cause deformation. Deflection_ Horizontal deflection is a form of bending in horizontal spanning members, and shortening of vertical load bearing members. Buckling_ is formed when the high compressive force exceeds the allowable loading capacity of a member and leads to failure.

6_EXTRA NOTES AND COMMENTS

I-Beam: high strength

& increase its stiffness

Bracing can stabilise the

structure, and transfer the

load more effectively.
