Note:
1. To calculate the project duration when the cost falls between the values in the above table, the following formula shall be used.
Calendar Days = [(given reference amount x reference duration per km. of road) + estimated amount per km. of road] + [duration of mob./demob. on the given reference amount]
2. Assumptions:
a. Duration includes MobilizationlDemobilization: Up to P5 Million - 10 c.d.; Above P5 Million up to P20 Million - 15 c.d.; Above P20 Million up to P50 Million - 20 c.d.; Above P50
Million up to P100 Million - 25 c.d. & Above P100 Million up to P150 Million - 30 c.d.;
b. Duration excludes Sundays, Holidays and Pre-determined Unworkable Days.
( 3. No standard duration was established for projects costing more than P150 Million. Computation shall be based on the PERT/CPM schedule, considering the use of optimum

additional resources.
