Task 1 (P1.1)
The use of materials in construction has changed over the years, look the list below and prepare a table indicating where and how they

are used in building industry example below:
Metals and alloys eg iron, steel, zinc, copper, brass, aluminium, lead;
Timber and timber products;
Clay products eg bricks, tiles;
Cements and concretes;
Plastics and other artificial materials;
Coatings and finishes eg paints, clear finishes, wood treatments

materials Internal External historical Other

Periodic symbol: Cu.
Density: 8930kg/m3 . Melting point: 1083˚C.
Thermal expansion: 0.0168mm/m/˚C (20-100˚).
Tensile strength: 210 – 240 N/mm2 (soft – half hard).
Hot and cold water pipework
Varying diameters from 10-50mm. and a thickness of 0.5mm

Calorifier, hot water cylinders

Electrical and electronic cabling.

Roof and cladding finish
The copper is rolled to thicknesses ranging between 0.5 and 1.0mm (1.5 – 3.0mm for curtain walling) but a 0.6 – 0.7mm thickness is

usually used for roofing. Allowing for seaming, 1m2 of copper roof weighs approximately 6.5kg.
Use of copper pipe in the Domestic housing market has been replaced plastic pipework

This market still exists although limited

cladding finish
have increased with use of lightweight building systems Also used as decorative finishes
Cooking vessels

Copper has also been used in the past for
Waterproofing of boats.

Task 2a (P1.2)
From the materials above create a table to identifying the following properties and provide data where relevant

Porosity and water absorption,
Thermal and moisture movement,
Thermal conductivity/resistivity,
Electrical conductivity/resistivity,
Specific heat capacity,

Task 2b
Rate which property are most important to material, discuss if necessary to clarify your rating
Task 3 (1.3)

Outline the use of construction material in the housing industry from the 1940 to the 1960
Comparing them with use of construction material 1970 to the 1990
And final what changes have been made in the last fifteen years

For each period identify the main driving forces behind each of construction period
Including any legislation or social events which you may feel relevant to your report. As well as details of the standard construction

materials of the day (roof, walls, doors and window materials)

As a guideline the following topics are suggested for inclusion in your report.
Energy efficiency
Environmental issues
Use of renewable resources
Task 4 (3.2)
Integrate building services

With respect to the services required to a UK commercial project, outline the utility services you would expect to find and identifying

a rule of thumb as to capacity/sizes for the attached three story office block.
Reference should be made to the building regulations were appropriate others sources of information such as the BSRIA and CIBSE
