MCS502

Unit Description and General Aims

The unit looks at Advanced Engineering Materials, covering Concrete Practice, Steel Practice and Wood, including areas on Concrete Durability and Deterioration and Steel Coatings and Corrosion Protection.

It is important to highlight that the section does not include other specialist Materials, as these materials, whilst critically important in the field of Structural Engineering, are beyond the scope of this course.

The unit explores the important role that the Structural Engineer undertakes in the understanding of the impact of different natural materials on the codes, the design and the project. It further highlights the critical decision making that is required in ascertaining the suitability of the materials for the project, the importance of defining the specific material requirements from the Codes of Good Practice, and providing clear specifications to ensure that all the materials used on the project are in accordance with the requirements of the relevant codes, and the design, and that the works are fit for purpose.

Further, the unit covers the key aspects of Durability and Corrosion protection that need to be considered to ensure that the design life of the works is assured.

The unit provides a focussed approach in considering natural materials, in evaluating all materials that are to be used on a project, whether they are included in this unit or not.

A review of a landmark failure is included to enable students to reflect on the implications of inadequate consideration of the project requirements, the codes, the specifications and the material selection, which all contributed to a devastating and costly failure, both in in terms of loss of life and reputation.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

      1. Make judgements on the role of the Structural Engineer in ensuring the successful evaluation of the relevant codes and the definition of the project specifications, design and material requirements.

         Bloom’s Level 5

      2. Judge and critique the key areas of expertise and techniques that are needed to evaluate and interrogate the Specifications required for the materials to be incorporated in a project.

         Bloom’s Level 5

      3. Evaluate the key variables associated with natural materials and be able to interpret their effect  on the construction materials, such as concrete, that are to be incorporated into the project.

         Bloom’s Level 5

      4. Determine the methods of communicating the key requirements for the materials, to be incorporated into the project with all the project role players.

         Bloom’s Level 5

      5. Synthesise the methodology that will be employed on the project to ensure that the project specifications are controlled and adequately documented.

         Bloom’s Level 6

       6.Construct the key Design deliverable of the project, and the design requirements to ensure that the works are fit for purpose and meet the required design life.

          Bloom’s Level 6
