Özet:

 


Duration and cost of a
construction project is estimated based on the construction schedule and cost
analysis which are arranged according to the quantity take-off data prepared
before the commencement of the construction. Construction schedule and budget
may deviate because of the unforeseeable factors which might happen during
construction. This situation would also affect cash-flow. Omission of updating the cash-flow because of the
heavy workload during the construction would prevent the foreknowledge of
balance of income and expenditure which may jeopardize financial situation of
the construction. In this study, a model is developed which construct a
relation between construction schedule and progress payments in order to obtain
most accurate and update cash-flow and prevent the aforementioned problems. To
accomplish this, all of the operation steps of quantity take-off are formulated
and the formulae are defined to spreadsheet application. Man-hour and durations
of activities are estimated by considering the quantity take-off data. Start
and finish dates of the activities are obtained by work planed which is
prepared by linear schedule. Costs of activities are determined by unit price
analysis and daily performed construction items and daily expenditures are
computed. Possible revisions
on the durations of the activities are updated together with the construction
schedule and the progress payments are recomputed without any human
intervention. Computations are executed and demonstrated on spreadsheet
application in order to make sure that all of the contractors can implement the
proposed method. The contractors would be able to update the cash-flow
immediately and foresee any adverse condition beforehand and may take
precautions.
