Potential construction constrains: Limited space for

constructing, Different height, materials and structural

system of the existing buildings

Links to other buildings: Connected the Eastern

Resource Centre (ERC) and Dong McConnell and build

as the space for science student centre

Construction type: TypeⅠ—the major building

elements are non-combustible materials, such as steel,

concrete, with the other combustible materials for the

ancillary in the primary structure

Structural System(s): the steel beams to support the

roof structure; timber plate with the steel frame inside

the roof

Materials: steel, concrete, timber, glass, marble

Other relevant comments: the use of acoustic linings

can absorb the sound, which can provide a quiet and

comfortable environment

Week 3 CASE STUDY SITE VISIT

Potential construction constrains: Similar to the first site

which includes limited space, Different height, materials of

the existing buildings, and long-history existing structure

for the two old brick buildings

Links to other buildings: build an infill building to fill the

gap and provide a connected entry between two old

existing buildings

Construction type: TypeⅠ—the major building elements

are non-combustible materials---steel and concrete

Structural System(s): steel beams melting to the bricks;

steel beams on a concrete slab which is the main

structure;

Materials: steel, concrete, timber, plywood, glass

Other relevant comments: the infill building mostly

choose the steel frame, which is more convenient for the

construction and save the constructing time.

Potential construction constrains limited

constructed area and working space, long-history

existing structure of the old building

Links to other buildings: the links between the

existing Queen's College Nicholas Laboratories, the

extension space and other colleges

Construction type: type Ⅳ: Using masonry built for

the exterior wall, which is non-combustible and the

interior elements of laminated wood

Structural System(s): masonry built the exterior wall

and using mortar paint the surface, which looks like

concrete; timber frame built the interior wall

structure, plywood for the door and enclosure

system

Materials: steel, concrete, timber, plywood, glass

Other relevant comments: using the cantilever slab

for awning

Potential construction constrains: the constraints and

consideration from the existing structure for the

reception

Links to other buildings: the extension reception area

from the end Dalton McCaughey Library

Construction type: type Ⅳ: Using concrete and steel

built for the exterior wall and structure, which is non-

combustible, and the interior elements of timber,

plywood

Structural System(s): aluminium alloy for the doors

and windows frame （lightweight structure）; steel

beams and trusses, columns built the roof system;

concrete force-slabs for the floor system; the normal

sheet glasses built the windows for the enclosure

system

Materials: steel, concrete, timber, glass, aluminium

alloy

Other relevant comments: as from the staff work in

this reception, the temperature in the reception is not

very suitable in summer due to the direction of the

building; the timber martials used for the interior

structure which provided a quite comfortable

environment for the staffs working inside.

Dig the hole for

the foundationo

Materials: steels,

concrete, plywood,

timbers

Stage: build for the

foundation

Casting foundation: Dig for a

foundation pit

Using the plywood as the

formwork, which used for

pouring the concrete

Materials: sand,

cement, macadam

Protect and repair this

small building as the

value of heritage site

Use of Strip footing: dig a

foundation ditch; bind the

reinforcing steel bar, then pouring

the concrete
