Dimensions and Project Delivery Flashcards
Why is over-dimensioning a problem in construction documents?
It can lead to inconsistencies when changes occur, making drawings harder to interpret and risking construction errors.
What is a recommended practice when using dimension strings in a plan?
Leave one segment of the dimension string blank to allow flexibility and avoid discrepancies.
When should you use ‘align’ or ‘centerline’ instead of exact dimensions?
When the design intent is alignment or centering rather than fixed distances.
What does ‘VIF’ mean in dimensions?
Verify in field – it means the dimension must be checked on-site.
What should dimensions always reference?
Known elements like column lines, exterior walls, or fixed shafts (e.g., stairwells).
Where should vertical dimensions be shown?
On elevations or sections, not on plans.
What is the proper reference point for vertical dimensions?
Top of structural floor, not finished floor.
Why avoid dimensioning to finished floor?
Because finish materials can change, affecting accuracy.
What are two schools of thought for dimensioning walls?
To framing (e.g., stud edges) or to finish (e.g., drywall surface).
Why must one dimensioning method be used consistently?
To maintain accuracy and prevent confusion during construction.
What is a door schedule used for?
To organize and present detailed door information such as size, location, type, and hardware.
What is typically included in a door schedule?
Door mark, room location, size, manufacturer, type, hardware, fire rating, frame info, finishes, and remarks.
Why include a ‘remarks’ column in a schedule?
To note unique features or additional instructions not covered by other columns.
What are key stages in producing contract documents?
Design Development (DD), 50% CDs, 90% CDs, and 100% CDs for construction.
What is the focus at 50% CDs?
Coordination between architect and consultants.
What is the goal at 90% CDs?
Ensure full coordination and verify code compliance, program, and consultant alignment.
What is the purpose of the 100% CD set?
Used for bidding; must be clear and complete for accurate, comparable bids.
How does design/bid/build work?
Client hires architect → full design → competitive bidding → GC builds.
How is design/build different?
One contract for design and construction; contractor involved early.
What is unique about fast track delivery?
Construction begins before design is complete via phased packages.
What challenge does fast track present?
Increased risk of errors and rework due to evolving design.
What is the core idea of integrated project delivery (IPD)?
All parties (owner, architect, contractor) collaborate from the start as one team.
What role does a construction manager (CM) play?
Acts on owner’s behalf, offers early cost control, and influences final drawings.
When does the CM gain control of project decisions?
After design development, when pricing is locked.
