Estimating calculators project basis

Build cable quantity, reel count, containment takeoff, labour-hours, quote and material-markup worksheets for Australian estimating. These calculators support Australian design, estimating, installation and verification preparation. Keep the circuit, equipment, route, supply arrangement and source data with the result before it is used in a project record.

Confirm the nominal 230/400 V a.c. or project-specific voltage basis, 50 Hz context where applicable, phase arrangement, metric units, manufacturer information, DNSP or authority conditions and current project documents before applying a result.

Check entered values, supply arrangement, cable or equipment data, product limits, DNSP or authority conditions and review limits before using the result.

Records covered

  • Cable cost and quantityEstimate cable quantity and material cost from entered route lengths. Inputs: Cable runs, length, waste factor and unit cost. Output: Estimating worksheet for local project records and manual review.
  • Cable reel countEstimate how many cable reels are needed from entered run lengths and reel length. Inputs: Cable description, run lengths, waste allowance and supplier reel length. Output: Reel count, order length, leftover length and utilisation for procurement review.
  • Cable tray quantityEstimate tray order length and unit count from entered containment route segments. Inputs: Tray description, route segments, waste allowance and supplied tray unit length. Output: Tray unit count, order length and surplus length for takeoff review.
  • Conduit quantityEstimate conduit order length and unit count from entered route, bend and waste values. Inputs: Conduit description, route segments, bend allowance, waste allowance and supplied unit length. Output: Conduit unit count, order length and surplus length for takeoff review.
  • Labour hoursEstimate task labour hours and crew-days from entered quantities and productivity assumptions. Inputs: Task rows, hours per unit, adjustment factors, crew size and working hours per day. Output: Total labour hours, crew-days and largest task contribution for estimate review.
  • Quote worksheetCombine entered material, labour, other cost, margin and GST values into a worksheet total. Inputs: Quote reference, material cost, labour hours, labour rate, other cost, margin and GST. Output: Subtotal, margin amount, GST and total inc GST for estimate review.

Review before applying

Estimating calculator results are preparation records. Keep entered values beside current Australian requirements, DNSP or authority conditions, manufacturer information and project documents before applying a result.

Recheck the selected calculator whenever the supply arrangement, equipment data, route length, tariff basis, measurement method or project document set changes.
