No. | Cost composition | Cost calculation |
|---|---|---|
(1) | Sub-engineering fee | =∑[(a) × (b)] |
 (a) | Unit cost | = (i) + (ii) + (iii) + (iv) |
  (i) | Labor cost | = Amount of labor × unit labor cost |
  (ii) | Material cost | = Amount of material × unit material cost |
  (iii) | Machine cost | = Amount of machine × unit machine cost |
  (iv) | Management cost | =[(i) + (iii)] × rate of management fee |
  (v) | Profit | Determined by manufacturers |
  (vi) | VAT | Determined by manufacturers |
 (b) | Sub-engineering quantity |  |
(2) | Cost of taking measures | =(c) + (d) |
 (c) | Cost for taking measures (countable) | =∑((b) × rate) |
 (d) | Cost for taking measures (uncountable) | = (vii) + (viii) |
  (vii) | Safety construction | = Base amount × rate of safe construction |
  (viii) | Other measures | = Base amount × rate of other measures as determined by management authority |
(3) | Other project cost | Provisional sums, cost of daywork, contracting management fee |
(4) | Pollution discharge cost | According to actual cost |
| Â | Cost of onsite assembly | = (1) + (2) + (3) + (4) |
