Assignment Brief and Guidance
Scenario

You are employed by a large general contractor, as a Design & Build Engineering Assistant in Sri Lanka. The company has recently appointed a new Managing Director who has decided to shift the company’s focus towards greater use of sustainable practices. To achieve this, the Managing Director has asked a number of staff to prepare a report on the materials for a construction project, with an idea to improve sustainability through material selection.’ You may take an already completed building project by your company as exemplary to do below tasks and express how better it could have been done in terms of science and materials.
Provide an Introduction to this report and background & layouts of the exemplary project and perform below tasks by referring assessment criteria.

Task 01: Review health and safety regulations and legislation associated with the storage, handling and use of materials on a construction site
Explain how to organizing a site regarding health and safety. You able to consider pre-construction phase and construction phase. Explain impact of regulations on the use, storage and handling of construction materials (P1)
Do a risk assessment of any critical construction work and assess how it can be used to address hazards. (M1)
Discuss some of safety arrangements of following activities. (D1)
Working at heights ( Guard rail, ladder, Roof, Platform, Scaffolding etc)
Moving, Lifting and handling loads
Site vehicle and Moving plants
Chemicals
PPE
Emergency Procedures

Task 2: Discuss the environmental and sustainability factors which impact on and influence the material choices for a construction project
Explain material environmental profiling and lifecycle assessment. Use a relevant material to exemplify your explanation. (P2)
Discuss the benefits of product declaration and environmental certification.(P3)
Produce a waste management plan for your exemplary project to explain the importance of using it in future projects. (M2)
Illustrate how the use of sustainable practices and considerations for material choice can improve the environmental rating of the completed building. (D2)

Task 03: Present material choice for your exemplary building using performance properties, experimental data, sustainability and environmental consideration.
3.1 Present the results of relevant testing procedures to identify performance characteristics of selected construction materials. (P4)
Discuss the results in terms of the material properties and regulatory requirements, highlighting any unexpected results and why these may occur. (P5)
Above criteria included in following Laboratory test.
Describe the purpose and procedure for following experiments associated with properties of construction material
cube test for concrete
slump test for concrete
ACV or AIV test for aggregates (Only purpose and procedure for AIV/ACV Test)
Analyze the observations & calculations, get the results & conclude.

3.2 Propose better construction materials for your exemplary project based upon their performance properties (P6)
Define the physical, mechanical, thermal and chemical properties such as density, specific gravity, porosity, strength, elasticity, plasticity, hardness, ductility, brittleness, creep, stiffness, fatigue, impact strength, toughness, thermal conductivity, corrosion resistance and electrical conductivity of construction materials with proper examples
Evaluate the properties and uses of following construction materials.
Concrete
Steel
Timber
Bricks and blocks
Choose a structural material and consider the effects of loading. Compare the behaviour and performance of other alternative materials. (M3)

Task 04: Evaluate the performance of your exemplary building in respect of its human comfort requirements.
Define a material selection strategy with regard to human comfort requirements. (P7)
Identify materials for a selected area within the building and explain how these contribute to a balanced indoor environment. (P8)
Perform calculations which relate to a selected area which has more than 1 layer of materials in wall. (lux levels, u-values, acoustic and ventilation). State the assumptions clearly. (M4)
Evaluate how the use of passive or active strategies can minimize energy, materials, water, and land use (D3)
