Assignment title Assignment 3
Understand the properties and use of construction materials and how integrate building services into the overall building design
Purpose of this assignment
Develop an understanding of concrete and the effects of poor quality control also to evaluate the use of different materials used as a structural member.

In addition to the above PASS criteria, this assignment gives you the opportunity to submit evidence in order to achieve the following MERIT and DISTINCTION grades
Merit grade

M2
select/design and apply appropriate methods/techniques a range of sources of information has been used Within task 1 and 2 of this assignment there is an opportunity to show a range of different public and professional organisational data
? complex information/data has been synthesised and processed Within task 3 of this assignment there is an opportunity to show how you have processed complex information and data in order to provide your report

M3 present and
communicate
appropriate findings ? the appropriate structure and approach has been used There is an opportunity throughout this assignment to show how an appropriate structure and approach has been used your reports
? a range of methods of presentation have been used and technical language has been accurately used
When responding to task 3 it will be important to ensure that any rule of thumb is associated with an iso standard measurement

Distinction grade

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
Copper

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

Also
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

Roofing
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

Strength,
Elasticity,
Porosity and water absorption,
Thermal and moisture movement,
Thermal conductivity/resistivity,
Electrical conductivity/resistivity,
Durability,
Workability,
Density,
Specific heat capacity,
Viscosity

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.
Construction
Refurbishment
Maintenance
Replacement
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
