Quality Management and Coordination Lecture 4

American University in Cairo School of Sciences and Engineering Department of Architectural Engineering AENG441 – Professional Practice, Design Management and Codes 1

Topics

2

Quality Management • Careful coordination of documents and work with consultants • Checklist for developing and coordinating working drawings

3

Quality Management General Concepts • Unacceptable number of errors in building design, documentation and professional practice.

4

Quality Management General Concepts • Quality Control procedures: Checking the work before it is distributed to the user. • Quality Control identifies error late in the process, when they are costly to correct.

5

Quality Management General Concepts • Quality Assurance • Prevent errors before they are made.

• Designing, documenting and constructing requires that proper resources and scrutiny are applied.

• Correct errors early before they are compounded.

• Limitation: Segmented not holistic!

Quality Management General Concepts • Total Quality Management TQM = QC + QA • Customer satisfaction (client, user, public, profession, …)

Quality Management Structural Integrity • Vertical Forces: Gravity - Load Soil characteristics - Bearing capacity Water in the soil - Upward pressure Differential settlement problems structural damage • Wet soil expansion • Frost - Frost line • Wind - Uplift forces on roofs - eaves overhangs and porch roofs • • • •

Quality Management Structural Integrity • Vertical Forces:

10

Quality Management Structural Integrity • Lateral Forces: • Horizontal forces • Below the surface of the ground: • Soil - subsurface walls - vertical slabs • Water in soil or expansive soil - subsurface drainage

11

Quality Management Structural Integrity • Lateral Forces: • Horizontal forces • Above the surface of the ground: • Wind: Location, surrounded, open, height, overturning moments. Inward and Outward pressures - resist racking and twisting forces.

Windows and openings, glazing - suction on roof surfaces - Mechanical anchoring and heavy ballast. Window frames - suction forces inward and outward.

12

Quality Management Structural Integrity • Lateral Forces: • Horizontal forces • Above the surface of the ground: • Earthquakes - direction, intensity and duration.

• Lightweight buildings of regular geometric shapes and stiffness tend to perform well.

• No extreme variations in strength or stiffness variations create torsion that alleviated by adding shear walls • A stiff core is not located asymmetrically in a building.

• No notches or reentrant corners to concentrate stresses.

• No soft story created by elevating structures on pilotis at the first story.
