Quality Management and Coordination Flashcards
What does the architect have to do with regards to the geotechnical report?
Verify that the required investigations have been made and that the construction documents incorporate the technical engineers findings.
What is Total Quality Management (TQM)? How is it different than quality control and quality assurance?
Quality control and assurance for enhanced CUSTOMER satisfaction.
Quality control: checking a dwg b4 distributing
Quality assurance: supplements quality control by requiring checks throughout the design process
Basic considerations for lateral structural stability an architect should take into account:
- No extreme variations on strength or stiffness (they tend to create torsion)
- Don’t place a stiff core asymmetrically in a building
- Avoid notches and reentrant corners
- Don’t create a “soft story” by elevating upper stories on pilotis (they need to be stiffened or braced)
Basic structural considerations an architect should take into account regarding vertical structure:
- Potential differential settlement caused by non uniform soil conditions
- Expansive soils, frost action, or high water table, all of which create upward pressure
- Wind forces creating uplift on roofs
5 more specific actions to address seismic and lateral loads…
- Reinforce underground walls to resist soil pressures
- Provide drains to alleviate/eliminate hydrostatic soil pressure.
- Detail windows and opening to resist wind pressures
- Provide mechanical connections or weight on roof membrane to resist uplift
- Shape buildings uniformly with uniform stiffness and strength to resist seismic
4 ways to floodproof a building
- Locate out of 100 year floodplain - BEST
- Lift above anticipated levels
- Dry floodproof: using water resistant materials and sealants to prevent water from entering
- Wet floodproof: allow water to enter and once it starts to recede, pump out standoff water
Main advantage of wet floodproofing and main advantage of dry floodproofing
Dry: interior surfaces don’t get wet
Wet: structure doesn’t have to be designed to resist the water pressure
Both types require firmly tied down structures however
Slope your roof at what pitch or higher to avoid most roof drainage problems
4:12
Sometimes a roofing system warranty depends on the ability of the company to:
- Pre-approve the contractor
- Inspect the installation
- Disclaim other elements such as flashing
Why shouldn’t you save money when specifying exterior joints and sealants?
Because the cost of failure is great but the cost of the material is small
Where do moisture problems usually start in an exterior wall surface? What should you do?
Where wall materials meet and between walls and doors, etch
Overlap or flash
Why use a backer rod beneath joint sealant?
Use if the depth of the joint is greater/deeper than the sealant depth required
Basic considerations for moisture control:
- Floodproof with your methods
- Provide flashing dtls @ all necessary roof joints
- Sealants or backing materials or overlaps at vertical wall junctions and openings
- Appropriate sealants with proper depth-to-width ratios
- Slope ground surfaces away from building
- Waterproof membranes, subsurface drains, sometimes even under floor slabs
- Vapor barrier on the warm side
3 decay resistant materials
Redwood cedar and concrete
Electrolysis is also known as ____ and occurs when …
Galvanic action…. When when 2 reactive surfaces come into contact (touching or through water transfer) and one corrodes the other
