Quantity take-off options inside the software

Quantity take –off

1. Determine the work activities = WBS2. Determine activities duration (Quantities +

Rawlinsons)3. Determine activities relationships =

dependencies & lags Finish to Start Start to Start Start to Finish

4. Review and analyse the programme5. Cost/resource allocation6. Resource levelling7. Implement the programme8. Monitor and control the programme9. Revise the database and record feedback

Programming steps

(adapted from Mubarak 2010)Taija Puolitaival, Department of Construction, Unitec 2014

WBS / Programme Distinction

WBS Comprehensive

classification of project scope

Contains no activity duration

No resource assignments

No dependencies

Programme Actual work to be

done (only the activities on the last level of the WBS)

Contains activity durations

Contains assignment of resources to activities

Contains dependencies Taija Puolitaival, Department of Construction, Unitec 2014

Quantity Take-off

Construction manager’s point of view - order of the activities- right size activities

how to build the building

vs.

Quantity surveyor’s point of view- what is the total amount of quantities

how much does it cost to build the building

1. Nature of the work/homogeneity2. Location/floor3. Size/duration4. Timing/chronology5. Responsibility6. Others

= programmer’s mentality in breaking down the project

(Mubarak 2010)
