- Rental rates not in the ACEL booklet are taken from rental rates computation, with operated rental rates preferred over bare rental rates
- The detailed unit cost analysis must indicate the make, model, and capacity of the equipment
- Mobilization and demobilization treated as a separate pay item, computed based on equipment requirements in the project proposal and contract booklet
- Mobilization and demobilization must not exceed 1% of the Estimated Direct Cost (EDC) of the civil works items

- The order defines Indirect Cost as the sum of:
- Overhead expenses ranging from 5% to 8% of the EDC, including:
- Engineering and Administrative Supervision

- Other unforeseen events
- Miscellaneous expenses ranging from 0.5% to 1% of the EDC, including:
- Laboratory tests for quality control
- Plan preparation
- Contractor’s profit margin of 8% to 12% of the EDC, depending on project size:
- 8% for projects above P5 Million and up to P5 Million
- 12% for projects above P5 Million (as stated in the table provided)
- VAT component equal to 12% of the sum of the EDC, OCM and Profit
- Overhead expenses ranging from 5% to 8% of the EDC, including:
OCM and profit ranges by EDC bands
- The order provides a table of percentages for OCM (Overhead, Contingencies, and Miscellaneous) and profit and their corresponding totals by EDC ranges.
- For Up to P5 Million, OCM is 12% and profit is 12%, with total indirect cost percent 24%.
- For Above P5 Million up to P50M (as presented), OCM is 9% and profit is 8%, with total indirect cost percent 17%.
- For Above P50M up to P150M, OCM is 7% and profit is 8%, with total indirect cost percent 15%.
- For Above P150M, OCM is 6% and profit is 8%, with total indirect cost percent 14%.
- The order instructs that the percentage to be used for Nos. B.1, B.2, and B.3 is governed by the OCM column in the tabulation and the profit percentage.
Required format and computation rules
- The order requires use of the prescribed format for the calculation of the BAC shown in Attachment “A”.
- Columns (1) to (4) are filled based on their respective labels in the format and are treated as self-explanatory in the instructions.
- The order requires the following calculation rules for the BAC format:
- Column (5) is the EDC of the work item as calculated and reflected in the cost analysis prepared by the Estimator.
- Columns (6) and (7) are the mark-ups in percent for OCM and profit.
- Column (8) is the total mark-up percent, computed as the sum of columns (6) and (7).
- Column (9) is the Peso value of the total mark-up, computed by multiplying column (8)’s total mark-up percent by the EDC (column 5).
- Column (10) is the VAT component, computed as 12% of the sum of columns (5) and (9).
- Column (11) is the total estimated Indirect Cost, computed as the sum of columns (9) and (10).
- Column (12) is the total estimated Total Cost, computed as the sum of columns (5) and (11).
- Column (13) is the unit cost for each item of works, computed by dividing the estimated total cost in column (12) by the total quantity in column (3).
- The order requires that the BAC be based on approval Bidding Documents containing the same work items and quantities as those for contractors to use in preparing their bid.
