This document discusses quality management in construction. It covers general concepts like quality control, quality assurance, and total quality management. It also discusses ensuring structural integrity by properly managing vertical forces like gravity, soil characteristics, and differential settlement, as well as lateral forces like wind, earthquakes, and soil movement. Additionally, it addresses managing water and moisture, durability and maintenance needs, environmental considerations, thermal and acoustic control, aesthetics, and following relevant codes and regulations. The overall goal is to carefully coordinate all building documentation and work to prevent errors and ensure customer satisfaction.

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

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

5. 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.

6. 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!

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

9. 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

Structural Integrity
• Vertical Forces:

11. 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

12. 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.

13. 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.
