Project planning for a road building project involves defining tasks, estimating resource needs and activity durations. Resource requirements are calculated based on activity duration, number of crews assigned, and resources used per crew. Estimating activity durations also considers work productivity levels. A hierarchical framework is then used to estimate durations for specific construction tasks like masonry work.

Where,
Rk
ij are the resources of type k required by activity ij,
Dij is the duration of activity ij, Nij is the number of standard crews allocated to activity ij,
Uk
ij is the amount of resource type k used per standard crew.
For example, if an activity required eight hours with two crews assigned and each crew
required three workers, the effort would be R = 8*2*3 = 48 labour-hours.
Resources such as labour requirements will vary in proportion to the work
