If you need formulas or detailed cost calculations, please specify the item or chapter.

Lead Details (MORTH Standard Data Book 1)

• Lead refers to the one-way distance (in km) materials are transported on site.
• Typical leads include:
  • L1: Mixing Plant to working site
  • L2: Earthwork borrow area to site
  • L3: Moorum/Natural granular material borrow area to site
  • L4: Fly ash source to site
  • L5: Sand source to site
  • L6: Sand source to Plant
  • L7: Aggregate quarry to working site
  • L8: Aggregate quarry to Plant
  • L9: Bitumen source to Plant
  • L10: HT Strands source to Plant

Usage:

• Leads are essential for calculating haulage costs and contractor profit.
• Used to estimate transportation cost in earthwork, aggregates, bitumen, etc.

Example Table: Lead Representation

Key Formula for Haulage Cost (Typical):

[ \text{Haulage Cost} = \text{Quantity} \times \text{Lead (km)} \times \text{Rate per km} ]

Super-Structure Cost Estimation Key Points (MORTH Standard Data Book 1, Clause 14.01):

Cost Components:

• a+b+c: Basic Cost of Labour, Material & Machinery for 120 cum concrete.
• d: Formwork and staging (% of a+b+c, varies with height and type).
• e: Overhead charges (applied on a+b+c+d).
• f: Contractor's profit (applied on a+b+c+d+e).

Formwork & Staging Percentage by Height and Type:

Cost Calculation Formula:

[ \text{Total Cost for 120 cum} = a + b + c + d + e + f ]

[ \text{Rate per cum} = \frac{a + b + c + d + e + f}{120} ]

Where:

• (d = \text{Formwork %} \times (a+b+c))
• (e = \text{Overhead %} \times (a+b+c+d))
• (f = \text{Profit %} \times (a+b+c+d+e))

Additional Notes:

• Cement, coarse and fine aggregates quantities are for estimation; actual as per mix design.
• Minor tools like vibrators are included in overhead charges.
• Water for curing and machinery costs (transit mixers, water tankers) depend on lead distance (L_1) and capacity.

Example: Formwork & Staging Cost for Height 5m to 10m (Solid Slab)

[ d = 23% \times (a+b+c) ]

Key Points:

• Hourly owning & operating cost includes:
  • Ownership Cost: Interest, insurance, depreciation, taxes.
  • Operational Cost: Fuel, lubricants, crew wages, repairs, supplies.

Sample Rates for Tippers (Transportation of Soil, GSB, WMM, Hot Mix):

Other Machinery Examples:

Notes:

• Output considered approx. 75% of rated capacity due to operational factors (Clause 6.2).
• Rates vary by machine size, power, and working conditions (e.g., road surface type).
