Mine owners have to update their closure study on the cycle the regulator sets. Perfect Contracting supplies the demolition and decommissioning part of it: what is on the site, how it comes down, what it will cost and how long it takes.

The study itself is written by your project managers or consultants. We give them contractor numbers to put in it instead of desktop estimates, and when the plant does come down we do the demolition, decommissioning and remediation works.

What Are Closure Studies?

A closure study that carries a real demolition method and a real price holds up better with the regulator and with the board. Desktop estimates for taking down a processing plant are usually wrong in both directions: they miss the hazardous materials and the sequencing, and they ignore the steel credit.

We have priced and pulled down the plant. That is the input we bring.

What we put into your closure study

Plant and structure inventory

Walk the site with your team and list every structure, vessel, conveyor and building that the study has to account for.
Flag the items that drive cost: refractory linings, insulated pipework, transformers, tanks with residue, structures over 15 metres.

Demolition and decommissioning method

Sequence for making the plant safe, isolating services and taking it down.
Plant list and crew, high reach, remote demolition and crane lifts where they are needed.
What can be done while the site is still operating and what has to wait for closure.

Hazardous materials assumptions

Asbestos, lead paint, SMF, PCB and process residue assumptions stated openly so the study can carry them as risks.
What a destructive survey would need to confirm before the price firms up.

Waste, salvage and steel credit

Tonnages by stream, recycling routes and licensed receiving facilities.
Scrap steel and equipment resale credited back against the cost, with the timing spelt out.

Indicative cost and programme

A contractor's price range and duration for the demolition scope, with the exclusions listed.
Updated at the next study cycle as the plant and the scrap market change.

We do not write the closure study, the rehabilitation plan or the ecology. Final landform, revegetation and monitoring belong to your environmental consultant.

Why get the contractor in at study stage

The number is real. It comes from a company that has priced and demolished processing plants, not from a rate table.
Fewer surprises later. Hazardous materials and sequencing get named in the study rather than found on the first day of demolition.
Steel credit counted. Most desktop closure estimates leave the scrap value out. It can change the provision materially.
One conversation. The people who price the study input are the people who run the job when closure comes.
