Aim
Science and material performance are intrinsically linked through the need to create structures and spaces that perform in both mechanical operation and in providing human comfort.
This unit aims to support students in making material choices to achieve the desired outcomes of a brief. This is approached from the perspective of materials being fit for purpose; as defined by testing standards and properties but also by consideration of the environmental impact and sustainability. Students will consider health and safety alongside the need to meet legislative requirements.
The topics covered in this unit include: health and safety; storage and use of materials; handling and problems associated with misuse and unprotected use; environmental and sustainable consideration in material choices; human comfort performance parameters. Material choice is developed through the understanding of testing procedures to establish conformity to standards and define performance properties. The performance of materials to satisfy regulations and provide appropriate comfort levels is addressed through design and calculations.
On successful completion of this unit, students will be able to make informed decisions regarding material choices, based on understanding the structural behaviour of materials established through recognised testing methods, sustainability, context of build and health and safety. Students will be able to perform the calculations necessary to establish anticipated performance of the materials in use and therefore determine their compliance with regulations and suitability.
Learning Outcomes
By the end of this unit, students will be able to:
LO1 Review health and safety regulations and legislation associated with the storage, handling and use of materials on a construction site
LO2 Discuss the environmental and sustainability factors that inform the material choices for a given construction project
LO3 Present material choices for a given project using performance properties, experimental data, sustainability and environmental consideration
LO4 Evaluate the performance of a given project in respect of its human comfort requirements.
