Construction Materials UNIT 1

What is the purpose of quality control in project implementation?

• To ensure the highest quality of work and extend the service life of any structure

• To check and regulate the use of construction materials and to economize on the cost of construction

• To measure the quality of materials by sight or other means

• To regulate the weight, population, or prices of materials

What is the importance of materials testing?

• To check and regulate the use of construction materials and to economize on the cost of construction

• To ensure the highest quality of work and extend the service life of any structure

• To measure the quality of materials by sight or other means

• To complement quality control in engineering works

What is the role of the Project Engineer?

• To supervise continuously the Contractor’s technicians/foremen in carrying out specified sampling, testing, and reporting works

• To prepare design mixes for concrete and asphalt mixtures

• To produce a complete, accurate, and cost-efficient building in accordance to the approved set of plans of the project

• To verify/audit and evaluate that the work is done in accordance with specifications
