Within task three the will be an opportunity toshow Effective thinking.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 theyare 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 treatmentsmaterials Internal External historical OtherCopperPeriodic 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 pipeworkVarying diameters from 10-50mm. and a thickness of 0.5mmAlsoCalorifier, hot water cylindersElectrical and electronic cabling.Roof and cladding finishThe 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 isusually 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 pipeworkRoofingThis market still exists although limitedcladding finishhave increased with use of lightweight building systems Also used as decorative finishesCooking vesselsCopper has also been used in the past forWaterproofing of boats.Task 2a (P1.2)From the materials above create a table to identifying the following properties and provide data where relevantStrength,Elasticity,Porosity and water absorption,Thermal and moisture movement,Thermal conductivity/resistivity,Electrical conductivity/resistivity,Durability,Workability,Density,Specific heat capacity,ViscosityTask 2bRate which property are most important to material, discuss if necessary to clarify your ratingTask 3 (1.3)Outline the use of construction material in the housing industry from the 1940 to the 1960Comparing them with use of construction material 1970 to the 1990And final what changes have been made in the last fifteen yearsFor each period identify the main driving forces behind each of construction periodIncluding any legislation or social events which you may feel relevant to your report. As well as details of the standard constructionmaterials of the day (roof, walls, doors and window materials)As a guideline the following topics are suggested for inclusion in your report.ConstructionRefurbishmentMaintenanceReplacementEnergy efficiencyEnvironmental issuesUse of renewable resourcesTask 4 (3.2)Integrate building servicesWith respect to the services required to a UK commercial project, outline the utility services you would expect to find and identifyinga 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 CIBSEEnd of Assignment.
