Construction and built environment

    Scenario An old mill store/warehouse is to be converted into a rural community centre which includes workshops, meeting hall shower facilities and kitchen areas. The overall size of the building is shown on the plan attached including window sizes, the door measures 2400mm x 1900mm, and is a standard timber construction. The second task will develop from the initial task 1, you are to prepare a report with detailed discussion on how material choice may be influenced by environmental and sustainability factors. Your report should clearly: a) Explain material environmental profiling and lifecycle assessment. Use a relevant material that can be used to improve the old mill store/ warehouse (e.g. concrete, steel, timber, glass etc.) to exemplify your explanation (P2).b) Discuss the benefits of product declaration and environmental certification with relevant examples (P3). c) Produce a waste management plan for the old mill store/warehouse project, taking into account a typical range of relevant waste materials. Please refer to The Clean Neighbourhoods and Environment Act 2005 (Section 54 of Part 5) which is the enabling legislation for the introduction of regulation requiring a Site Waste Management Plan (SWMP) on projects worth more than £250, 000 effective from April, 2008 (M2). d) For the foundation of the building, Concrete has been identified as one of the best materials of choice. Present the results of relevant concrete testing procedures to identify performance characteristics of the selected construction materials (P4). e) Discuss the results of the concrete tests in terms of the material properties and regulatory requirements, highlighting any unexpected results and why these may occur. (P5). f) Select the best construction materials for the old mill store/warehouse project based upon their performance properties in use (P6). g) Assess the effects of loading structural materials and compare the behaviours andperformance of materials which could be used for the same function.  (M3)   TASK 2.2 LO4 (P7, P8, M4, D2 and D3) As part of the conversion of the old mill store/warehouse into a rural community centre which is a standard timber construction. The walls are constructed of standard brick and block (to be designed) with a solid plaster coating on the internal leaf, the insulation is to be designed. The windows are currently single glazed steel frame construction, U-Value to be determined. The floor is a concrete slab and insulation, which is to have a screed finish. The roof is to be designed, but must conform to a warm roof scenario, in its construction, and the roof covering is to be designed as well as additional materials to conform to standards. You are the lead designers of the construction work with a clear focus on a sustainable build. Additional requirements include, maintaining the humidity of the building space at a set constant value of 50%, assume that there are 1.5 air changes per hour to the building, and there is a need to ensure that sound reverberation and background ambient sound levels are maintained at appropriate levels. The building will need to be brought up to modern standards and efficiencies whilst maintaining the character of the property. All work must conform to building regulations/legislative standards. The brief for the conversion is to upgrade it to meet all current regulations and should include:• A kitchen space• A large meeting room/multi-purpose space• Storage• A small meeting room• Two workshops• Toilet facilities to mobility requirements. As part of the building design for thermal comfort you are required to perform various calculations involving heat flow to determine the energy requirements for the structure. The initial phase will be to calculate the heat lost (or gained) through the external walls. The external walls of the structure comprise of the following construction:
