Constructability Flashcards
(20 cards)
What is constructability in architecture?
The consideration of construction challenges in the design to ensure the project can be realistically built.
Why is constructability important?
It helps avoid design issues that lead to costly delays, RFIs, or rework during construction.
Give an example of a constructible detail versus a less constructible one.
Baseboard molding (constructible) hides floor/wall material edges. A reveal detail (less constructible) exposes edges, requiring perfect cuts.
How does constructability differ from means and methods?
Constructability relates to design feasibility. Means and methods are construction procedures decided by the contractor.
What type of knowledge is required for a constructability review?
Construction knowledge, design experience, procurement, and field operations.
When should constructability be evaluated?
During the design phase, as part of QA/QC procedures.
How can constructability reduce project costs?
By avoiding complex or impractical details that are expensive or time-consuming to build.
How can construction managers help with constructability?
By advising on methods, procurement, logistics, labor availability, and scheduling constraints.
What kind of insight can a CM provide regarding building materials?
They can advise on availability, shipping distances, and installation timelines.
How can constructability affect the project schedule?
Complex details or long lead times can delay construction. Constructable designs align with schedule constraints.
What is the role of a mock-up in constructability?
Mock-ups allow performance testing and visual evaluation to catch issues before full-scale construction.
What’s the difference between in-place and external mock-ups?
In-place are built in final location. External are standalone samples used for early evaluation.
How can constructability be evaluated without a CM?
Through peer reviews, consultant input, and possibly jurisdictional reviews.
What should an architect do if a detail is not constructible?
Consult with the contractor or expert to revise the detail to maintain design intent and buildability.
How do RFIs relate to constructability?
RFIs may be issued when a design detail cannot be built as shown or lacks clarity.
How does constructability relate to warranty issues?
Inappropriate material selection may void warranties, impacting long-term performance and cost.
Why should critical info be located logically in the drawing set?
So that contractors can find and implement it correctly, reducing construction errors.
What is an example of a site constraint affecting constructability?
Urban sites with limited access may require alternate materials or building sequences.
Why might a CM suggest metal studs instead of CMUs?
To accelerate enclosure and meet tight construction deadlines.
What can mock-ups test aside from aesthetics?
Air/water infiltration, material compatibility, and system performance.
