Whole-life value tool

GRP whole-life cost calculator

GRP can cost more at purchase but less across the asset life when installation time, corrosion maintenance, access disruption and replacement cycles are included.

Quick comparison calculator

Use this as an early conversation tool, not a formal cost plan. Enter an estimated purchase, installation, annual maintenance and replacement cycle for two options.

Enter values to compare a 20-year cost.

Costs that are often missed

  • Painting, coating inspection, touch-up and corrosion repair.
  • Scaffold, possession, permit, isolation or shutdown time.
  • Manual handling and plant time for heavier materials.
  • Replacement disruption where a cheaper material fails earlier.
  • Safety risk from wet, degraded, corroded or slippery routes.
  • Admin cost of repeated small repairs instead of planned replacement.

Expanded practical guidance

Use whole-life cost as a structured comparison

A useful whole-life comparison includes purchase, preparation, installation, access, inspections, coatings, corrosion repair, disruption, replacement and disposal. The calculator is an estimating aid rather than a guaranteed project cost.

Set the same scope

Compare materials performing the same duty over the same study period, including supports, fixings, surface treatment and access requirements.

Record assumptions

State labour rates, inspection frequency, coating cycles, outage costs, replacement timing and discounting assumptions so the result can be challenged.

Test uncertainty

Run more than one scenario. A base, optimistic and cautious case shows which assumptions drive the result.

Information to confirm

  • Equivalent product duty and design life
  • Installation and access costs
  • Inspection, maintenance and interruption
  • Replacement, disposal and residual risk

Practical questions

Does the calculator prove GRP is always cheaper?

No. It structures a comparison. The outcome depends on the project inputs and should be checked against real quotations and asset requirements.

Which assumptions matter most?

Corrosion exposure, access difficulty, maintenance frequency, labour, outages and replacement timing often have a strong effect.
