Project Planning Flashcards
How are concrete structure quantities estimated?
Volume (CY)
How are concrete formwork quantities estimated?
SF or SFCA
How are Structural Frames & Reinforcement quantities estimated?
Weight (quantity x length x unit wt). Unit is in tons or pounds
What is the zero position and how do you account for it?
Initial position of a quantity. Ex. a post is to be placed every 5 ft along 25 ft. 25/5 = 5. But must add 1 for zero position = 6 posts
How are roof panel quantities estimated?
SF of roof or # of panels needed
Masonry Structures - how to add mortar length
Only need to add mortar thickness on one length and one width side
What is Free Float?
days a particular activity may be delayed before impacting critical path schedule
What is Total Float?
days between the finish of the last critical activity and project completion date
3 types of cost estimating?
Analogous - using historical information to estimate for current project and duration (least accurate method)
Parametric: use a base unit cost to estimate project cost and duration
Three-point = combination of cost extremes to get idea of avg cost
What is a dummy activity?
Activity that does not consume any resource (time, labor) Typically shown as dashed line. Allows for activities to have multiple successors
Who should be contacted to discuss federal aid?
FHWA (Federal Highway Administration)
Types of Billing Methods
Lump sum/Fixed price
-single cost for entire project based on detailed estimated
-useful for jobs with clearly defined scopes and no price fluctuations
Cost-Plus
-total project cost plus fee for project
-Contractors apply a fee/charge either as fixed or percentage (if job costs rise)
-useful for projects with more undefined scope or if project needs to be completed quickly
Unit Price
-bill a customer at fixed price per unit. Job is divided into segments
-common for highway and utility companies taking on projects with repetitive work
-provides leeway for tacking on additional work/materials
Definitive Estimate
forecast of project cost based on conceptual and detailed information
What is crash cost?
New cost - old cost
